GET_datatype_ARG Function

This function determines the value of an argument in a deferred call.

The AnyData type supports the following user-defined types: object types, collections and REFs. Not all types supported by this function can be enqueued by the AnyData_ARG procedure in the DBMS_DEFER package.

The returned text for type arguments includes the following values: type owner, type name, type version, length, precision, scale, character set identifier, character set form, and number of elements for collections or number of attributes for object types. These values are separated by a colon (:).

See Also: "datatype_ARG Procedure" The Replication Management tool's online help for information about displaying deferred transactions and error transactions in the Replication Management tool Oracle9i SQL Reference and Oracle9i Application Developer's Guide - Object-Relational Features for more information about the AnyData datatype This function uses abbreviations for some datetime and interval datatypes. For example, TSTZ is used for the TIMESTAMP WITH TIME ZONE datatype. For information about these abbreviations, see "Abbreviations for Datetime and Interval Datatypes".

Syntax

Depending upon the type of the argument value that you want to retrieve, the syntax for the appropriate function is as follows. Each of these functions returns the value of the specified argument.
