Operators

This document describes the operators precedence, comparison functions and operators, logical operators, and assignment operators.

NameDescription
AND, &&Logical AND
=Assign a value (as part of a SET statement, or as part of the SET clause in an UPDATE statement)
:=Assign a value
BETWEEN ... AND ...Check whether a value is within a range of values
BINARYCast a string to a binary string
&Bitwise AND
~Bitwise inversion
|Bitwise OR
^Bitwise XOR
CASECase operator
DIVInteger division
/Division operator
=Equal operator
<=>NULL-safe equal to operator
>Greater than operator
>=Greater than or equal operator
ISTest a value against a boolean
IS NOTTest a value against a boolean
IS NOT NULLNOT NULL value test
IS NULLNULL value test
->Return value from JSON column after evaluating path; equivalent to JSON_EXTRACT()
->>Return value from JSON column after evaluating path and unquoting the result; equivalent to JSON_UNQUOTE(JSON_EXTRACT())
<<Left shift
<Less than operator
<=Less than or equal operator
LIKESimple pattern matching
-Minus operator
%, MODModulo operator
NOT, !Negates value
NOT BETWEEN ... AND ...Check whether a value is not within a range of values
!=, <>Not equal operator
NOT LIKENegation of simple pattern matching
NOT REGEXPNegation of REGEXP
||, ORLogical OR
+Addition operator
REGEXPPattern matching using regular expressions
>>Right shift
RLIKESynonym for REGEXP
SOUNDS LIKECompare sounds
*Multiplication operator
-Change the sign of the argument
XORLogical XOR

Operator precedence

Operator precedences are shown in the following list, from highest precedence to the lowest. Operators that are shown together on a line have the same precedence.

INTERVAL
BINARY, COLLATE
!
- (unary minus), ~ (unary bit inversion)
^
*, /, DIV, %, MOD
-, +
<<, >>
&
|
= (comparison), <=>, >=, >, <=, <, <>, !=, IS, LIKE, REGEXP, IN
BETWEEN, CASE, WHEN, THEN, ELSE
NOT
AND, &&
XOR
OR, ||
= (assignment), :=

For details, see Operator Precedence.

Comparison functions and operators

NameDescription
BETWEEN ... AND ...Check whether a value is within a range of values
COALESCE()Return the first non-NULL argument
=Equal operator
<=>NULL-safe equal to operator
>Greater than operator
>=Greater than or equal operator
GREATEST()Return the largest argument
IN()Check whether a value is within a set of values
INTERVAL()Return the index of the argument that is less than the first argument
ISTest a value against a boolean
IS NOTTest a value against a boolean
IS NOT NULLNOT NULL value test
IS NULLNULL value test
ISNULL()Test whether the argument is NULL
LEAST()Return the smallest argument
<Less than operator
<=Less than or equal operator
LIKESimple pattern matching
NOT BETWEEN ... AND ...Check whether a value is not within a range of values
!=, <>Not equal operator
NOT IN()Check whether a value is not within a set of values
NOT LIKENegation of simple pattern matching
STRCMP()Compare two strings

For details, see Comparison Functions and Operators.

Logical operators

NameDescription
AND, &&Logical AND
NOT, !Negates value
||, ORLogical OR
XORLogical XOR

For details, see MySQL Handling of GROUP BY.

Assignment operators

NameDescription
=Assign a value (as part of a SET statement, or as part of the SET clause in an UPDATE statement)
:=Assign a value
