>From IB documentation:

isc_dsql_execute_immediate()
prepares the DSQL statement specified in statement, executes it once, and discards it.
The statement must not be one that returns data (i.e., it must not be a SELECT or EXECUTE PROCEDURE statement).
If statement requires input parameter values (i.e., if it contains parameter markers), these values must be supplied in
the input XSQLDA, xsqlda.

isc_dsql_exec_immed2()
prepares the DSQL statement specified in statement, executes it once, and discards it.
The statement can return a single set of values (i.e, it can be an EXECUTE PROCEDURE or singleton SELECT)
in the output XSQLDA.
