Library: ib_udf
Changed in: 1.0
Description: Returns the ASCII character corresponding to the integer value passed in.
Return type: CHAR(1)
Syntax (unchanged):
ascii_char (intval)
Declaration (changed):
DECLARE EXTERNAL FUNCTION ascii_char INTEGER RETURNS CSTRING(1) FREE_IT ENTRY_POINT 'IB_UDF_ascii_char' MODULE_NAME 'ib_udf'The declaration has been changed to reflect the fact that the UDF as such returns a 1-character C string, not an SQL CHAR(1) as stated in the InterBase declaration. The engine will pass it on to the caller as a CHAR(1) though.
