Specifies the name of a structure declared in the host program as an SQLDA to which SQL writes information about select list items. Precompiled programs can use the embedded SQL statement INCLUDE SQLDA to automatically insert a declaration of an SQLDA structure, called SQLDA, in the program when it precompiles the program. Programs that use the SQL module language must explicitly declare an SQLDA. Either precompiled or SQL module language programs can explicitly declare additional SQLDAs, but must declare them with unique names.
