LOCATE

Syntax

LOCATE(substr,str), LOCATE(substr,str,pos)

Description

The first syntax returns the position of the first occurrence of substring substr in string str. The second syntax returns the position of the first occurrence of substring substr in string str, starting at position pos. Returns 0 if substr is not in str.

LOCATE() performs a case-insensitive search.

If any argument is NULL, returns NULL.

INSTR() is a synonym of LOCATE() without the third argument.
