Using ROWID for processing IUD where possible. Anytime you can process by using the row rowid in. Oracle table you will get the best performance. This is. especially true in IUD situations. Time reductions for some. Oracle Plsql Open Cursor For Update Examples' title='Oracle Plsql Open Cursor For Update Examples' />UPDATEs were reduced from 1. ROWID processing. By combining. bulk bind and ROWID even greater improvements should be realized. The easiest to see is a bulk delete type. Essentially you John Beresniewiczs. Figure 1. 4 shows.

This script depends on a work table that can be. The. table acts as a repository for the target tables ROWID values. ROWID is a unique identifier for each row in a table and is an. Oracle internal column for each table. Also placed in the table. ROWNUM that is generated as requested by a. The set of ROWNUM varies according to the select. However, ROWNUMs for a given select are in. First, the script creates a complete set of ROWNUM. ROWID entries for the target table. In the example script in. Figure 1. 5, all of the ROWIDs for the table are gathered, however. WHERE clause is required to the line sqlcom INSERT. INTO temptab SELECT rownum, rowid FROM tabname The WHERE clause could even be passed into the. VARCHAR2 variable. Once we have this ROWIDs the. ROWNUM pseudo column provides a 1 to n correlation to the selected. ROWIDs we can now keep track of the The procedure accepts a rows and table name. ROWNUM and ROWID data and using a standard cursor. ORA 0. 15. 55 errors in the process. Improper use of datatypes can result in implicit. Implicit type conversions result in the. Always use TYPE and ROWTYPE to capture the types from. Using DBMSPROFILER the developer can easily see. A review. of loop logic for nested loops is imperative to ensure redundant. Look at the. procedure in Figure 1. CREATE OR.
