The MySQL AND, OR and NOT Operators
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 byAND
are TRUE. - The
OR
operator displays a record if any of the conditions separated byOR
is TRUE.
The NOT
operator displays a record if the condition(s) is NOT TRUE.
AND Syntax
SELECT column1, column2, ...
FROM table_name
WHERE condition1 AND condition2 AND condition3 ...;
OR Syntax
SELECT column1, column2, ...
FROM table_name
WHERE condition1 OR condition2 OR condition3 ...;
NOT Syntax
SELECT column1, column2, ...
FROM table_name
WHERE NOT condition;
