Can I use EXEC SQL statment with #define in AIX. Some thing written below

#define  EXEC_SQL_PREPARE(STATEMENT)    \
        {                               \
        if (handle_type == UDR_DEFAULT_HANDLE) \
           EXEC SQL PREPARE STATEMENT FROM :stmtstr;    \
        else   \
           EXEC SQL AT :phandle PREPARE STATEMENT FROM :stmtstr;        \
        }
