ASCII_CHAR()
Added in: 2.1
Description
Returns the ASCII character corresponding to the number passed in the argument.
Result type: [VAR]CHAR(1) CHARACTER SET NONE
Syntax
ASCII_CHAR (<code>) <code> ::= an integer in the range [0..255]
Important:
- If the external function ASCII_CHAR is declared in your database, it will override the internal function. To make the internal function available, DROP or ALTER the external function (UDF).
- If you are used to the behaviour of the ASCII_CHAR UDF, which returns an empty string if the argument is 0, please notice that the internal function correctly returns a character with ASCII code 0 here.
