C Data Type Definition

typedef unsigned short GRAPHIC;

Usage

Fixed length graphic data that requires padding uses the ideographic space (U+3000).

If the function result type is fixed length graphic data, then the result argument points to a data area with the size set to the maximum defined by the RETURNS clause in the CREATE FUNCTION statement.

Here is an example using CHARACTER(n) CHARACTER SET GRAPHIC in a UDF definition and C function declaration.

SQL Function Definition Equivalent C Function Declaration

RETURNS CHARACTER(12) CHARACTER SET GRAPHIC
 ...;
void f1( GRAPHIC *a,
         GRAPHIC *result,
   ... )
{  ... }
