This MySQL function returns the starting position of the first occurrence of the substring in the string given as the first argument.

Syntax

Below is the syntax for this command. Text within square brackets (i.e, [ and ] ) are optional. Choices are separated by bars (i.e, | ). Ellipses preceded by a comma indicates a repeating pattern.

INSTR(string, substring)

Explanation

This function returns the starting position of the first occurrence of the substring in the string given as the first argument. The index of the first position is 1. This function is case-insensitive unless one of the arguments given is a binary string. For an example of this function, see the example in the description of INSERT( ). INSTR( ) is similar to for one of the syntaxes of LOCATE( ), but the parameters are given in a different order.
