[Firebird-test] UDFs in procedure

[greg <na...@fr...>]

Hello,
how to call UDFs function in procedure ?

For example, I would like to create an alias of the UDF ASCII_CHAR  :


CREATE FUNCTION CHR(num NUMBER)
 RETURN CHAR
  IS chrRet CHAR(1);
BEGIN
 RETURN(ASCII_CHAR(num));
END;

This doesn't work....and I don't know why

Thanks.
