RESEQUENCE_COLLECTION Procedure

15.25 RESEQUENCE_COLLECTION Procedure

For a named collection, updates the seq_id value of each member so that no gaps exist in the sequencing. For example, a collection with the following set of sequence IDs (1,2,3,5,8,9) becomes (1,2,3,4,5,6).

If a collection does not exist with the specified name for the current user in the same session and for the current application ID, an application error occurs.

Syntax

APEX_COLLECTION.RESEQUENCE_COLLECTION (
    p_collection_name   IN VARCHAR2);

Parameters

Parameter	Description
`p_collection_name`	The name of the collection to resequence. An error is returned if this collection does not exist with the specified name of the current user and in the same session.

Example

This example resequences the DEPARTMENTS collection to remove gaps in the sequence IDs.

BEGIN
    APEX_COLLECTION.RESEQUENCE_COLLECTION (
        p_collection_name => 'DEPARTMENTS');
END;
