Comparing Dates in SQL - Mathematics Grade 1 - Exercises with solutions

Master date comparisons in SQL: operators, functions, and comparisons through these 10 detailed exercises.

Solutions: Exercises 1 to 10
1 Basic date comparison
Exercise 1
How do I compare two dates in SQL to determine which is earlier?
Difficulty: Beginner Time: ~3 minutes Skills: Date Comparison Operators
Definition:

Date comparison: SQL uses standard comparison operators to compare dates: <, >, =, <> or !=

Note: SQL compares dates chronologically, where earlier dates are considered "less than" later dates.

Step-by-step comparison method:
  1. Represent dates in standard format (YYYY-MM-DD)
  2. Use comparison operators to evaluate relationships
  3. Understand that earlier dates are less than later dates
Original Query
SELECT '2023-01-15' < '2023-01-20'
Result
TRUE
Step 1: Understand date representation

SQL recognizes dates in formats like 'YYYY-MM-DD': '2023-01-15' represents January 15, 2023

Step 2: Apply comparison operator

'2023-01-15' < '2023-01-20' evaluates if January 15 comes before January 20

Step 3: Determine chronological order

Since January 15 occurs before January 20, the result is TRUE

SELECT '2023-01-15' < '2023-01-20' returns TRUE
Final answer:

'2023-01-15' < '2023-01-20' = TRUE

Applied rules:

• Date ordering: Earlier dates are less than later dates

• Standard format: YYYY-MM-DD ensures proper chronological comparison

• Comparison operators: Same as for numbers but applied chronologically

• Practice Tip: Think of dates as positions on a timeline: left (earlier) < right (later)

Related Examples:
  • '2023-02-01' > '2023-01-31' = TRUE - February comes after January
  • '2023-03-10' = '2023-03-10' = TRUE - Same dates are equal
  • '2022-12-31' < '2023-01-01' = TRUE - End of year before next year
Quick Tips:
  • SQL automatically handles leap years and month lengths in date comparisons
  • Always use consistent date formats to avoid errors
  • Chronological thinking: earlier dates have "smaller" values than later dates
Frequently Asked Questions:

Q: Can I compare dates in different formats?
A: No, always use consistent formats. Most SQL databases expect YYYY-MM-DD format.

Q: What happens with invalid dates?
A: SQL will generate an error. Always ensure dates are valid (e.g., no February 30).

2 Greater than operator
Exercise 2
How do I use the greater than operator to find dates that come after a specific date?
Difficulty: Beginner Time: ~4 minutes Skills: Date Comparison, Greater Than Operator
Definition:

Greater than operator: > returns TRUE when the left date occurs after the right date chronologically

Note: This operator is commonly used to filter records that occurred after a certain point in time.

Step-by-step comparison method:
  1. Identify the reference date to compare against
  2. Use the > operator to find dates occurring later
  3. Structure query to return matching records
Original Query
SELECT date_col FROM table WHERE date_col > '2023-06-01'
Result
Returns dates after June 1, 2023
Step 1: Set the reference date

Define '2023-06-01' as the cutoff date for comparison

Step 2: Apply the greater than operator

date_col > '2023-06-01' finds dates that occur after June 1, 2023

Step 3: Interpret the results

Any date after June 1, 2023 (like June 2, July 15, etc.) will satisfy the condition

WHERE date_col > '2023-06-01' returns dates after June 1, 2023
Final answer:

This query returns all dates occurring after June 1, 2023

Applied rules:

• Chronological order: Later dates are greater than earlier dates

• Filtering: Use WHERE clause to filter based on date conditions

• Practical use: Commonly used for finding recent records or future events

• Practice Tip: Remember: dates further right on timeline have greater values

Related Examples:
  • WHERE date_col > '2023-12-25' - Finds dates after Christmas 2023
  • WHERE date_col > '2023-02-28' - Finds dates after end of February
  • WHERE date_col > '2023-01-01' - Finds dates after New Year's Day
Quick Tips:
  • Use greater than for "after" conditions: birthday > '2000-01-01' means born after 2000
  • Combine with other operators for ranges: date > 'start' AND date < 'end'
  • Think of timeline: dates to the right have greater values than those to the left
Frequently Asked Questions:

Q: What if I want dates on or after a specific date?
A: Use the greater than or equal operator: date_col >= '2023-06-01'

Q: Can I use this with time components?
A: Yes, datetime comparisons also work: '2023-06-01 10:30' > '2023-06-01 09:00'

3 Less than operator
Exercise 3
How do I use the less than operator to find dates that come before a specific date?
Difficulty: Beginner Time: ~4 minutes Skills: Date Comparison, Less Than Operator
Definition:

Less than operator: < returns TRUE when the left date occurs before the right date chronologically

Note: This operator is commonly used to filter records that occurred before a certain point in time.

Step-by-step comparison method:
  1. Identify the reference date to compare against
  2. Use the < operator to find dates occurring earlier
  3. Structure query to return matching records
Original Query
SELECT date_col FROM table WHERE date_col < '2023-06-01'
Result
Returns dates before June 1, 2023
Step 1: Set the reference date

Define '2023-06-01' as the cutoff date for comparison

Step 2: Apply the less than operator

date_col < '2023-06-01' finds dates that occur before June 1, 2023

Step 3: Interpret the results

Any date before June 1, 2023 (like May 30, April 15, etc.) will satisfy the condition

WHERE date_col < '2023-06-01' returns dates before June 1, 2023
Final answer:

This query returns all dates occurring before June 1, 2023

Applied rules:

• Chronological order: Earlier dates are less than later dates

• Filtering: Use WHERE clause to filter based on date conditions

• Practical use: Commonly used for finding old records or past events

• Practice Tip: Remember: dates further left on timeline have lesser values

Related Examples:
  • WHERE date_col < '2023-01-01' - Finds dates before 2023
  • WHERE date_col < '2023-02-28' - Finds dates before end of February
  • WHERE date_col < '2023-12-25' - Finds dates before Christmas
Quick Tips:
  • Use less than for "before" conditions: birthday < '2010-01-01' means born before 2010
  • Combine with other operators for ranges: date > 'start' AND date < 'end'
  • Think of timeline: dates to the left have lesser values than those to the right
Frequently Asked Questions:

Q: What if I want dates on or before a specific date?
A: Use the less than or equal operator: date_col <= '2023-06-01'

Q: Can I use this with time components?
A: Yes, datetime comparisons also work: '2023-06-01 08:00' < '2023-06-01 09:30'

Solutions: Exercises 4 to 5
4 Equal operator
Exercise 4
How do I find records with dates that match a specific date?
Definition:

Equal operator: = returns TRUE when both dates are identical

Note: This operator is used to find exact date matches, often for specific events or appointments.

Step-by-step comparison method:
  1. Specify the exact date to match
  2. Use the = operator to find exact matches
  3. Structure query to return matching records
Original Query
SELECT date_col FROM table WHERE date_col = '2023-06-01'
Result
Returns only June 1, 2023
Step 1: Specify the target date

Define '2023-06-01' as the exact date to match

Step 2: Apply the equal operator

date_col = '2023-06-01' finds records with exactly this date

Step 3: Interpret the results

Only records with the exact date June 1, 2023 will be returned

WHERE date_col = '2023-06-01' returns only June 1, 2023
Final answer:

This query returns only records with the exact date June 1, 2023

Applied rules:

• Exact matching: Only identical dates return TRUE

• Filtering: Use WHERE clause to filter based on exact date conditions

• Practical use: Commonly used for finding specific events or appointments

• Practice Tip: Remember: = means exact match, not range

Related Examples:
  • WHERE date_col = '2023-01-01' - Finds records on New Year's Day
  • WHERE date_col = '2023-12-25' - Finds records on Christmas Day
  • WHERE date_col = '2023-07-04' - Finds records on Independence Day
Quick Tips:
  • Use equal for exact date matches: appointment_date = '2023-06-15'
  • Combine with other conditions: date = '2023-06-01' AND status = 'active'
  • Be precise with formatting: '2023-06-01' ≠ '2023-6-1' in most systems
Frequently Asked Questions:

Q: Does this work with datetime values?
A: Yes, but time components must also match exactly: '2023-06-01 10:00:00' = '2023-06-01 10:00:00'

Q: What if I want dates within a day range?
A: Use BETWEEN or combine with other operators: date >= 'start' AND date <= 'end'

5 Not equal operator
Exercise 5
How do I find records with dates that do NOT match a specific date?
Definition:

Not equal operator: <> or != returns TRUE when dates are different

Note: This operator is used to exclude specific dates from results.

Step-by-step comparison method:
  1. Specify the date to exclude
  2. Use the <> or != operator to find non-matching dates
  3. Structure query to return all other dates
Original Query
SELECT date_col FROM table WHERE date_col <> '2023-06-01'
Result
Returns all dates except June 1, 2023
Step 1: Specify the date to exclude

Define '2023-06-01' as the date to exclude from results

Step 2: Apply the not equal operator

date_col <> '2023-06-01' finds all dates except June 1, 2023

Step 3: Interpret the results

All dates except June 1, 2023 will be returned

WHERE date_col <> '2023-06-01' returns all dates except June 1, 2023
Final answer:

This query returns all dates except June 1, 2023

Applied rules:

• Exclusion: Only different dates return TRUE

• Filtering: Use WHERE clause to exclude specific date conditions

• Practical use: Commonly used for excluding holidays or specific dates

• Practice Tip: Remember: <> and != are equivalent operators

Related Examples:
  • WHERE date_col != '2023-01-01' - Excludes New Year's Day
  • WHERE date_col <> '2023-12-25' - Excludes Christmas Day
  • WHERE date_col != '2023-07-04' - Excludes Independence Day
Quick Tips:
  • Use not equal for exclusions: date_col != '2023-06-01' excludes that date
  • Combine with other operators: date != 'holiday' AND date < 'end_date'
  • Both <> and != work the same way in most SQL databases
Frequently Asked Questions:

Q: What's the difference between <> and != ?
A: There is no functional difference; both represent "not equal". != is more familiar to programmers.

Q: How does NULL affect not equal comparisons?
A: NULL values never equal anything, including themselves. Use IS NULL or IS NOT NULL for NULL checks.

Solutions: Exercises 6 to 10
6 Between operator
Exercise 6
How do I find records with dates that fall within a specific range?
Definition:

Between operator: BETWEEN returns TRUE when a date falls inclusively within a specified range

Note: The range includes both the start and end dates (inclusive boundaries).

Step-by-step range method:
  1. Specify the start and end dates of the range
  2. Use the BETWEEN operator to define inclusive boundaries
  3. Structure query to return dates within the range
Original Query
SELECT date_col FROM table WHERE date_col BETWEEN '2023-06-01' AND '2023-06-30'
Result
Returns dates from June 1 to June 30, 2023
Step 1: Define the range boundaries

Set '2023-06-01' as start and '2023-06-30' as end of the range

Step 2: Apply the BETWEEN operator

date_col BETWEEN '2023-06-01' AND '2023-06-30' finds dates in June 2023

Step 3: Understand inclusivity

Both June 1 and June 30 are included in the results

WHERE date_col BETWEEN '2023-06-01' AND '2023-06-30' returns June dates
Final answer:

This query returns all dates from June 1 to June 30, 2023 (inclusive)

Applied rules:

• Inclusive range: Both boundary dates are included in results

• Chronological order: Start date should be before or equal to end date

• Practical use: Commonly used for monthly reports, quarterly analysis

• Practice Tip: BETWEEN is equivalent to: date >= start AND date <= end

Related Examples:
  • WHERE date_col BETWEEN '2023-01-01' AND '2023-12-31' - Full year 2023
  • WHERE date_col BETWEEN '2023-03-01' AND '2023-05-31' - First quarter (Jan-Mar)
  • WHERE date_col BETWEEN '2023-07-04' AND '2023-09-04' - Summer period
Quick Tips:
  • BETWEEN includes both boundary dates (unlike mathematical intervals)
  • Always specify earlier date first: BETWEEN 'start' AND 'end'
  • Equivalent to: date >= 'start' AND date <= 'end' (inclusive on both ends)
Frequently Asked Questions:

Q: What happens if I reverse the dates in BETWEEN?
A: The query will return no results since no date can be simultaneously less than the first date and greater than the second.

Q: Can I use BETWEEN with datetime values?
A: Yes! BETWEEN works with datetime: '2023-06-01 09:00:00' AND '2023-06-01 17:00:00'

7 Date function
Exercise 7
How do I extract just the date part from a datetime value?
Definition:

Date function: DATE() extracts the date portion from a datetime value, removing time components

Note: Different SQL databases may have different syntax (DATE(), CAST(), etc.) for date extraction.

Step-by-step extraction method:
  1. Identify the datetime column containing date and time
  2. Apply the DATE() function to extract just the date part
  3. Compare the extracted date as needed
Original Value
'2023-06-15 14:30:25'
Function Applied
DATE('2023-06-15 14:30:25')
Result
'2023-06-15'
Step 1: Identify the datetime value

Start with a datetime value like '2023-06-15 14:30:25'

Step 2: Apply the DATE function

DATE('2023-06-15 14:30:25') removes the time component

Step 3: Get the result

The result is '2023-06-15' with only the date part remaining

Step 4: Use in comparison

Now compare the extracted date: DATE(datetime_col) = '2023-06-15'

DATE('2023-06-15 14:30:25') = '2023-06-15'
Final answer:

DATE() function extracts '2023-06-15' from '2023-06-15 14:30:25'

Applied rules:

• Date extraction: Remove time components for pure date comparison

• Database differences: Syntax varies between SQL implementations

• Practical use: Useful when comparing dates ignoring time of day

• Practice Tip: Use when datetime fields contain time but only date matters

Related Examples:
  • DATE('2023-01-01 23:59:59') = '2023-01-01' - End of day still same date
  • DATE('2023-12-31 00:00:01') = '2023-12-31' - Beginning of day same date
  • WHERE DATE(created_at) = '2023-06-15' - Find all records from specific date
Quick Tips:
  • Use DATE() when you need to ignore time portions in datetime fields
  • Be aware that different databases may use different functions (CAST, CONVERT)
  • DATE() is useful for daily reports where time doesn't matter
Frequently Asked Questions:

Q: What's the difference between DATE() and other functions?
A: Different databases use different functions: MySQL uses DATE(), SQL Server uses CAST(), PostgreSQL has multiple options.

Q: Can I use this with comparison operators?
A: Yes! DATE(datetime_col) < '2023-06-01' compares extracted dates.

8 DATEDIFF function
Exercise 8
How do I calculate the number of days between two dates?
Definition:

DATEDIFF function: DATEDIFF() calculates the difference between two dates in specified units (days, months, years)

Note: Different SQL databases have different syntax for DATEDIFF (MySQL, SQL Server, etc.).

Step-by-step calculation method:
  1. Identify the two dates to compare
  2. Use DATEDIFF to calculate the difference
  3. Specify the unit of measurement (usually days)
Original Dates
'2023-06-15' and '2023-06-10'
Function Applied
DATEDIFF('day', '2023-06-10', '2023-06-15')
Result
5 days
Step 1: Identify the two dates

Start with two dates: '2023-06-10' and '2023-06-15'

Step 2: Apply the DATEDIFF function

DATEDIFF('day', '2023-06-10', '2023-06-15') calculates days between dates

Step 3: Get the result

The result is 5 days (June 10 to June 15 is 5 days)

Step 4: Interpret the sign

Positive result means second date is after first; negative means before

DATEDIFF('day', '2023-06-10', '2023-06-15') = 5 days
Final answer:

There are 5 days between June 10 and June 15, 2023

Applied rules:

• Date arithmetic: Calculate intervals between dates

• Database differences: Syntax varies between SQL implementations

• Positive/negative: Sign indicates direction of difference

• Practice Tip: Remember the order: DATEDIFF(start, end) gives days from start to end

Related Examples:
  • DATEDIFF('day', '2023-01-01', '2023-01-31') = 30 days - January duration
  • DATEDIFF('day', '2023-06-15', '2023-06-10') = -5 days - Negative when reversed
  • WHERE DATEDIFF('day', start_date, end_date) > 7 - Events longer than a week
Quick Tips:
  • Positive result means the second date is after the first date
  • Negative result means the second date is before the first date
  • Use for calculating durations, age, time intervals
Frequently Asked Questions:

Q: What if I want months or years instead of days?
A: Change the unit parameter: DATEDIFF('month', start, end) or DATEDIFF('year', start, end).

Q: How does it handle leap years?
A: SQL automatically accounts for leap years in date calculations.

9 Date formatting
Exercise 9
How do I format dates to display in different ways?
Definition:

Date formatting: Functions like DATE_FORMAT() or FORMAT() convert dates to different string representations

Note: Different SQL databases use different formatting functions and syntax.

Step-by-step formatting method:
  1. Identify the date to format
  2. Select the desired format pattern
  3. Apply the formatting function
Original Date
'2023-06-15'
Function Applied
DATE_FORMAT('2023-06-15', '%Y-%m-%d')
Result
'2023-06-15'
Step 1: Identify the date to format

Start with a standard date: '2023-06-15'

Step 2: Choose the format pattern

Use format codes: %Y for 4-digit year, %m for month, %d for day

Step 3: Apply the formatting function

DATE_FORMAT('2023-06-15', '%Y-%m-%d') maintains the same format

Step 4: See alternative formats

Other formats: '%M %d, %Y' gives 'June 15, 2023'

DATE_FORMAT('2023-06-15', '%Y-%m-%d') = '2023-06-15'
Final answer:

Date formatting converts dates to various string representations

Applied rules:

• Display formatting: Changes appearance without changing actual date

• Database differences: Functions vary between SQL implementations

• Format codes: %Y=year, %m=month, %d=day, %M=month name

• Practice Tip: Format for display; compare with original date values

Related Examples:
  • DATE_FORMAT('2023-06-15', '%M %d, %Y') = 'June 15, 2023'
  • DATE_FORMAT('2023-06-15', '%d/%m/%Y') = '15/06/2023'
  • DATE_FORMAT('2023-06-15', '%Y-%m-%d') = '2023-06-15' (default)
Quick Tips:
  • Use formatting for display purposes, not for date comparisons
  • Different databases use different format functions (DATE_FORMAT, FORMAT, TO_CHAR)
  • Common format codes: %Y (4-digit year), %m (month), %d (day), %M (month name)
Frequently Asked Questions:

Q: Should I format dates for comparisons?
A: No, always compare original date values. Format only for display purposes.

Q: How do I convert formatted strings back to dates?
A: Use STR_TO_DATE() in MySQL or similar functions in other databases.

10 Complex date queries
Exercise 10
How do I combine multiple date comparison operators in one query?
Definition:

Complex date queries: Combining multiple date conditions using logical operators (AND, OR, NOT)

Note: Complex queries allow sophisticated filtering based on multiple date criteria.

Step-by-step complex query method:
  1. Identify all date conditions needed
  2. Use logical operators to combine conditions
  3. Apply parentheses to control precedence
  4. Test the query logic carefully
Original Query
SELECT * FROM events WHERE date_col BETWEEN '2023-06-01' AND '2023-06-30' AND date_col != '2023-06-04'
Condition 1
BETWEEN '2023-06-01' AND '2023-06-30'
Condition 2
!= '2023-06-04'
Result
June dates except June 4
Step 1: Identify the first condition

Find dates in June: date_col BETWEEN '2023-06-01' AND '2023-06-30'

Step 2: Add the exclusion condition

Exclude June 4: date_col != '2023-06-04'

Step 3: Combine with AND operator

Both conditions must be true for a record to be included

Step 4: Interpret the result

Returns all June dates except June 4, 2023

Query returns June dates except June 4, 2023
Final answer:

Combines range selection with exclusion: June dates except June 4

Applied rules:

• Logical combinations: AND, OR, NOT to connect conditions

• Precedence: Use parentheses to control evaluation order

• Complex filtering: Sophisticated date-based queries

• Practice Tip: Test each condition separately before combining

Related Examples:
  • WHERE date > '2023-01-01' AND date < '2023-12-31' - All dates in 2023
  • WHERE date = '2023-07-04' OR date = '2023-12-25' - Specific holidays
  • WHERE date BETWEEN '2023-01-01' AND '2023-03-31' AND date != '2023-02-14' - Q1 except Valentine's
Quick Tips:
  • Use parentheses to group related conditions: (date1 > start AND date1 < end)
  • AND means all conditions must be true; OR means any condition can be true
  • Test complex queries with simple cases first
Frequently Asked Questions:

Q: What's the order of operations for logical operators?
A: NOT is evaluated first, then AND, then OR. Use parentheses to override.

Q: How do I debug complex date queries?
A: Break them into smaller parts and test each condition separately.

Key Laws, Methods, Rules, and Definitions
date1 < date2
Date Comparison Operator
Key definitions:

Date comparison: Evaluating temporal relationships between dates using operators (<, >, =, etc.)

Date function: Manipulating or extracting date components for analysis

Chronological order: Earlier dates have "less than" relationship with later dates

Complete methodology:
  1. Analyze the date requirement: Identify what temporal relationship to evaluate
  2. Choose the operator: Select appropriate comparison operator (<, >, =, BETWEEN, etc.)
  3. Apply the method: Execute the date comparison or function
  4. Verify the result: Check that the comparison makes chronological sense
Tip 1: Always use consistent date formats (YYYY-MM-DD) to avoid errors.
Tip 2: Think of dates as positions on a timeline: left (earlier) < right (later).
Tip 3: BETWEEN includes both boundary dates (inclusive range).
Tip 4: Use date functions to extract components when time portions are not needed.
Common errors: Mixing date formats, forgetting inclusivity of BETWEEN, confusing date vs datetime, incorrect operator usage.
Exam preparation: Memorize comparison operators, understand BETWEEN inclusivity, practice date function syntax, verify chronological logic.
Functions to memorize:

• Comparison operators: < (less than), > (greater than), = (equal), <> or != (not equal)

• Range operator: BETWEEN start AND end (inclusive on both ends)

• Date functions: DATE() to extract date part, DATEDIFF() for date differences

• Logical operators: AND, OR, NOT to combine conditions

• Formatting: DATE_FORMAT() or similar to change date appearance

Rules and Methods for Date Comparisons in SQL
date1 < date2
Less Than Date Comparison
Operator 1
date1 < date2
Date 1 before Date 2
Operator 2
date1 > date2
Date 1 after Date 2
Operator 3
date1 BETWEEN start AND end
Date within range (inclusive)

Key Takeaways

  • Date comparisons use standard operators but with chronological meaning
  • Earlier dates are considered "less than" later dates on timeline
  • BETWEEN includes both boundary dates (unlike mathematical intervals)
  • Use date functions to manipulate or extract date components
  • Combine conditions with logical operators for complex queries

Questions & Answers

Question: I don't understand why '2023-01-01' < '2023-01-02' is TRUE. Isn't 2 bigger than 1?

Answer: Great question! The key is understanding that date comparisons work differently than regular number comparisons:

  • With dates, we compare chronologically (by time order), not numerically
  • January 1, 2023 comes BEFORE January 2, 2023 on the calendar
  • In SQL, earlier dates are considered "less than" later dates

Think of it like a timeline: January 1 is to the left of January 2, so it has a "smaller" value in chronological terms.

Example: On a timeline, '2023-01-01' is positioned to the left of '2023-01-02', so '2023-01-01' < '2023-01-02' is TRUE.

Question: When I use BETWEEN '2023-06-01' AND '2023-06-30', does it include June 30th?

Answer: Yes, the BETWEEN operator is inclusive of both boundary dates:

  • BETWEEN '2023-06-01' AND '2023-06-30' includes BOTH June 1st AND June 30th
  • This means all dates from June 1 to June 30 (including both endpoints) are included
  • This is different from mathematical intervals where sometimes endpoints are excluded

In SQL, BETWEEN is equivalent to: date >= '2023-06-01' AND date <= '2023-06-30'

Tip: Remember that BETWEEN means "between and including the two values" in SQL.

Question: What's the difference between <> and != in SQL? Which one should I use?

Answer: Both <> and != mean exactly the same thing in SQL:

  • Both operators mean "not equal to"
  • date1 <> date2 is identical to date1 != date2
  • They both return TRUE when the dates are different

Which one to use is mostly a matter of preference:

  • <> is the official SQL standard
  • != is more familiar to programmers from other languages
  • Both work in most modern SQL databases

Pick whichever feels more intuitive to you - they work identically!
