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

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

Note: If the HIGH_NOT_PRECEDENCE SQL mode is enabled, the precedence of NOT is the same as that of the ! operator. See Section 5.2.6, “SQL Modes”.

The precedence of operators determines the order of evaluation of terms in an expression. To override this order and group terms explicitly, use parentheses. For example:

mysql> SELECT 1+2*3;
        -> 7
mysql> SELECT (1+2)*3;
        -> 9
