CHR

Syntax

CHR(N)

Description

CHR() interprets each argument N as an integer and returns a VARCHAR(1) string consisting of the character given by the code values of the integer. The character set and collation of the string are set according to the values of the character_set_database and collation_database system variables.

CHR() is similar to the CHAR() function, but only accepts a single argument.

CHR() is available in all sql_modes.
