Identifying an SQLDA in C or C++
A descriptor-name can be specified in the CALL, DESCRIBE, EXECUTE, FETCH, and OPEN statements. When the host application is written in C or C++, descriptor-name can be a pointer variable with pointer notation.
For example, descriptor-name could be
declared as
sqlda *outsqlda;
Afterwords,
it could be used in a statement like the following: EXEC SQL DESCRIBE STMT1 INTO DESCRIPTOR :*outsqlda;
