This document discusses various SQL operators used in queries. It describes arithmetic, bitwise, comparison, compound, logical, LIKE, IN, BETWEEN operators and provides examples of their usage. Examples show how to use operators to filter records based on conditions, search for patterns, specify multiple values, and select values within a range. Combining operators like AND, OR, and NOT is also demonstrated.

3. MySQL Arithmetic Operators
Operator Description Example Result
+ Add SELECT 30 + 20; 50
- Subtract SELECT 30 - 20; 10
* Multiply SELECT 30 * 10; 300
/ Divide SELECT 30 / 5; 6
% Modulo SELECT 30 % 5; 0

4. Bitwise Operators
Operator Description
AND Bitwise AND
OR Bitwise OR
<> NOT
By: Ms. Rubab For DIT

5. Comparison Operators
Operator Description Example
= Equal to SELECT * FROM Products WHERE Price = 18;
> Greater than SELECT * FROM Products WHERE Price > 18;
< Less than SELECT * FROM Products WHERE Price < 18;
>= Greater than or equal to SELECT * FROM Products WHERE Price >= 18;
<= Less than or equal to SELECT * FROM Products WHERE Price <= 18;
<> Not equal to SELECT * FROM Products WHERE Price <> 18;

6. MySQL
Compound
Operators
Operator Description
+= Add equals
-= Subtract equals
*= Multiply equals
/= Divide equals
%= Modulo equals
&= Bitwise AND equals
^-= Bitwise exclusive equals
|*= Bitwise OR equals

7. MySQL
Logical
Operators
OPERATOR DESCRIPTION
ALL TRUE if all the subquery values meet the condition
AND TRUE if all the conditions separated by AND is TRUE
ANY TRUE if any of the subquery values meet the condition
BETWEEN TRUE if the operand is within the range of comparisons
EXISTS TRUE if the subquery returns one or more records
IN TRUE if the operand is equal to one of a list of
expressions
LIKE TRUE if the operand matches a pattern
NOT Displays a record if the condition(s) is NOT TRUE
OR TRUE if any of the conditions separated by OR is TRUE
SOME TRUE if any of the subquery values meet the condition
By: Ms. Rubab For DIT

8. SQL And , OR & NOT
The WHERE clause can be combined with AND, OR,
and NOT operators.
The AND and OR operators are used to filter records based
on more than one condition:
• The AND operator displays a record if all the conditions
separated by AND are TRUE.
• The OR operator displays a record if any of the
conditions separated by OR is TRUE.
• The NOT operator displays a record if the condition(s) is
NOT TRUE.

9. AND syntax
SELECT column1, column2, ...
FROM table_name
WHERE condition1 AND condition2 AND condition3 ...;
Example
SELECT ID, name,marks
FROM students
WHERE class=‘DIT-II’ AND Marks>=15;
By: Ms. Rubab For DIT

10. OR Syntax
SELECT column1, column2, ...
FROM table_name
WHERE condition1 OR condition2 OR condition3 ...;
Example
SELECT ID, name,marks
FROM students
WHERE class=‘DIT-II’ OR class=‘CIT’;
By: Ms. Rubab For DIT

11. NOT Syntax
SELECT column1, column2, ...
FROM table_name
WHERE condition1 NOT ;
Example
SELECT ID, name,marks
FROM students
WHERE NOT class=‘DIT-II’ ;
By: Ms. Rubab For DIT

12. Combining AND, OR and NOT
You can also combine the AND, OR and NOT operators.
Example:
SELECT * FROM studnets
WHERE marks>=15 AND (class=‘DIT-II' OR class=‘CIT’)
By: Ms. Rubab For DIT

13. SQL LIKE Operator
The LIKE operator is used in a WHERE clause to search for a
specified pattern in a column.
There are two wildcards often used in conjunction with
the LIKE operator:
• The percent sign (%) represents zero, one, or multiple
characters
• The underscore sign (_) represents one, single character
Note: MS Access uses an asterisk (*) instead of the percent sign
(%), and a question mark (?) instead of the underscore (_).
The percent sign and the underscore can also be used in
combinations!

14. LIKE Syntax
SELECT column1, column2, ...
FROM table_name
WHERE columnN LIKE pattern;
Example:
SELECT * FROM students
WHERE name LIKE '%a’;
This query will return all the students with names
ending with an a.
By: Ms. Rubab For DIT

15. More examples
SELECT * FROM students
WHERE name LIKE'%or%’;
This SQL statement selects all students with a name that
have "or" in any position
SELECT * FROM students
WHERE name LIKE’_a’;
This SQL statement selects all students with a name that
have “a" in the second position of their name
By: Ms. Rubab For DIT

16. Examples continued..
SELECT * FROM students
WHERE name LIKE’a__%’;
This SQL statement selects all students with name that
starts with ‘a’ and is atleast 3 characters long.
SELECT * FROM students
WHERE name LIKE’a%o’;
This SQL statement selects all students with name that
starts with ‘a’ and ends with ‘o’.
By: Ms. Rubab For DIT

17. More examples..
SELECT * FROM students
WHERE name NOT LIKE ‘a%’;
This SQL statement selects all students with name that
doesn't starts with ‘a’.
By: Ms. Rubab For DIT

18. SQL IN Operator
The IN operator allows you to specify multiple values in
a WHERE clause.
The IN operator is a shorthand for multiple OR conditions.
IN Syntax
SELECT column_name(s)
FROM table_name
WHERE column_name IN (value1, value2, ...);
By: Ms. Rubab For DIT

19. Examples
SELECT * FROM studets
WHERE address IN (‘sobhodero’,‘hinjorja’,’Naogoth’);
The above SQL statement selects all student that are
located in ‘sobhodero’, ‘hinjorja’, ’Naogoth’
SELECT * FROM students
WHERE address
NOT IN (‘sobhodero’,‘hinjorja’,’Naogoth’);
The above SQL statement selects all customers that are
not located in ‘sobhodero’, ‘hinjorja’, ’Naogoth’:
By: Ms. Rubab For DIT

20. SQL BETWEEN Operator
• The BETWEEN operator selects values within a given
range. The values can be numbers, text, or dates.
• The BETWEEN operator is inclusive: begin and end values
are included.
SYNTAX:
SELECT column_name(s)
FROM table_name
WHERE column_name BETWEEN value1 AND value2;
By: Ms. Rubab For DIT

21. Example
SELECT * FROM studnets
WHERE marks BETWEEN 10 AND 20;
This SQL statement selects all students with a marks
between 10 and 20:
SELECT * FROM studnets
WHERE marks NOT BETWEEN 10 AND 20;
This SQL statement selects all students with a marks
not between 10 and 20
By: Ms. Rubab For DIT

22. BETWEEN Text Values Example
SELECT * FROM students
WHERE name BETWEEN ’Amir’ AND ‘Zaheer’ ORDER BY ID;
The above query selects all the students names
between Amir and Zaheer and orders them by their ID
Number
By: Ms. Rubab For DIT

23. BETWEEN with IN Example
SELECT * FROM students
WHERE marks BETWEEN 10 AND 20
AND class NOT IN (‘DIT-I’,’CIT’);
This query returns all the students with marks
between 10 and 20 , and who are not in DIT-I and CIT
