Oracle Objects for OLE provides tight integration with PL/SQL stored
procedures. Oracle Objects for OLE (OO4O), supports PL/SQL stored procedures,
PL/SQL tables and PL/SQL cursors etc. The PL/SQL bind (in/out) variables are
supported through the OraParameter's Add method. The
PL/SQL table (in/out) variable is supported through the AddTable method.
The stored procedure block is executed either
through the CreateSQL method or ExecuteSQL method.
Oracle Objects for OLE supports the SQL statement objects for PL/SQL stored
The Refresh method on this SQL statement object is a
faster and easier way to talk to stored procedure for different values for
PL/SQL bind (in/out) variables without reparsing the PL/SQL block.
Oracle Objects for OLE returns the cursor created in
the stored procedure or anonymous PL/SQL block as a READONLY dynaset object,
which is helpful in cases in which the business rules are encapsulated centrally
in the Oracle server. In order to do this, you must assign the cursor variable
as an OraParameter object of type ORATYPE_CURSOR. After executing the
stored procedure, the Value property of this OraParameter object
returns a read only dynaset object. For more information see Multiple Cursor Return from a PL/SQL
Procedure . This dynaset
object can be treated in the same way as other dynaset objects. OO4O also
returns a PL/SQL cursor as a read only dynaset object through the CreatePLSQLDynaset method.
