3.10.1 Additional types

The Informix-special "string" pseudo-type for storing right-trimmed character string data is now supported in Informix-mode without using typedef. In fact, in Informix-mode, ECPG refuses to process source files that contain typedef sometype string;

EXEC SQL BEGIN DECLARE SECTION;
string userid;           /* this variable will contain
                            trimmed data */
EXEC SQL END DECLARE SECTION;

EXEC SQL FETCH MYCUR INTO:userid;
