BEGINCREATE Static Procedure

This procxedure creates a new instance of ANYTYPE which can be used to create a transient type description.

   typecode       IN PLS_INTEGER,
   atype          OUT NOCOPY AnyType);

Parameters

Table 105-2 BEGINCREATE Procedure Parameters

`atype`	AnyType for a transient type

typecode

Use a constant from DBMS_TYPES package. Typecodes for user-defined type:

can be DBMS_TYPES.TYPECODE_OBJECT

DBMS_TYPES.TYPECODE_VARRAY or

DBMS_TYPES.TYPECODE_TABLE

Typecodes for builtin types:

DBMS_TYPES.TYPECODE_NUMBER etc.

SETINFO Member Procedure

This procedure sets any additional information required for constructing a COLLECTION or builtin type.

Syntax

MEMBER PROCEDURE SetInfo(
   self          IN OUT NOCOPY AnyType,
   prec          IN PLS_INTEGER,
   scale         IN PLS_INTEGER,
   len           IN PLS_INTEGER,

   elem_count    IN PLS_INTEGER DEFAULT 0);

Parameters

Table 105-3 SETINFO Procedure Parameters

Parameter	Description
`self`	The transient ANYTYPE that is being constructed.
`prec, scale` (OPTIONAL)	Required if typecode represents a NUMBER. Give precision and scale. Ignored otherwise.
`len` (OPTIONAL)	Required if typecode represents a RAW, CHAR, VARCHAR, or VARCHAR2 type. Gives length.
`csid, csfrm` (OPTIONAL)	Required if typecode represents types requiring character information such as CHAR, VARCHAR, VARCHAR2, or CFILE.
`atype` (OPTIONAL)	Required if collection element typecode is a user-defined type such as TYPECODE_OBJECT, etc. It is also required for a built-in type that needs user-defined type information such as TYPECODE_REF. This parameter is not needed otherwise.
The Following Parameters Are Required For Collection Types:
`elem_tc`	Must be of the collection element's typecode (from DBMS_TYPES package).
`elem_count`	Pass 0 for elem_count if the self represents a nested table (TYPECODE_TABLE). Otherwise pass the collection count if self represents a VARRAY.

Exceptions
