C Data Type Definition

typedef unsigned char BYTE;

Usage

Fixed length byte data that requires padding uses a binary zero as its pad character.

If the function result type is fixed length byte 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 BYTE in a UDF definition and C function declaration.

SQL Function Definition Equivalent C Function Declaration
CREATE FUNCTION F1 (
  A BYTE(30) )
RETURNS BYTE(12)
 ...;
void f1( BYTE a[30],
         BYTE *result,
   ... )
{  ... }
