ADD_OLEARGS built-in
Description
Establishes the type and value of an argument that will be passed to the OLE object’s method.
Syntax
PROCEDURE ADD_OLEARG
(newvar NUMBER, vtype VT_TYPE := VT_R8);
...or...
PROCEDURE ADD_OLEARG
(newvar VARCHAR2, vtype VT_TYPE := VT_BSTR);
...or...
PROCEDURE ADD_OLEARG
(newvar OLEVAR, vtype VT_TYPE := VT_VARIANT);
Built-in Type unrestricted procedure
Parameters
newvar The value of this argument. Its type (NUMBER,
VARCHAR2, or OLEVAR) is its FORMS or PL/SQL data
type.
vtype The type of the argument as understood by the OLE method
Usage Notes
For a NUMBER argument, the default is VT_TYPE :=
VT_R8.
For a VARCHAR2 argument, the default is VT_TYPE :=
VT_BSTR.
For an OLEVAR argument, the default is VT_TYPE :=
VT_VARIANT.
A separate ADD_OLEARG call is needed for each argument to be passed. The calls should be in order,
starting with the first argument.
A list of the supported OLE VT_TYPEs can be found in OLE Variant Types .
