The following example shows how to define SQL_TEXT and include the sqltypes_td.h header file in the file that defines a UDF:
#define SQL_TEXT Latin_Text #include "sqltypes_td.h"
Alternatively, you can use the following line to include the sqltypes_td.h header file:
#include <sqltypes_td.h>
Using angle brackets (< >) or double quotation marks (" ") affects the path that the C preprocessor uses to search for the sqltypes_td.h header file.
