[Chapter 5] 5.7 PLVcmt: Commit Processing
Chapter 5PL/Vision Package Specifications 5.7 PLVcmt: Commit ProcessingThe PLVcmt (PL/Vision CoMmiT) package provides a programmatic interface to the execution of commits, rollbacks, and the setting of savepoints. See Chapter 20, PLVcmt and PLVrb: Commit and Rollback Processing for details. 5.7.1 Controlling commit activity PROCEDURE turn_on;Enables commit processing in PLVcmt. This is the default. PROCEDURE turn_off;Disables commit processing in PLVcmt. When this program is called in the current session, the COMMIT statement will not be executed. FUNCTION committing RETURN BOOLEAN;Returns TRUE if commit processing is being performed by PLVcmt.5.7.2 Logging commit activity PROCEDURE log;Requests that, whenever a COMMIT is performed, a message be sent to the PL/Vision log. PROCEDURE nolog;Do not log a message with the COMMIT. FUNCTION logging RETURN BOOLEAN;Returns TRUE if currently logging the fact that a commit was performed by PLVcmt.5.7.3 Performing commits PROCEDURE increment_and_commit (context_in IN VARCHAR2 := NULL);Increments the counter and commits if a commit point has been reached. PROCEDURE perform_commit(context_in IN VARCHAR := NULL);The PLVcmt package's version of COMMIT. I could probably get away with calling this program commit, but I avoid using keywords even when the compiler doesn't seem to get confused.5.7.4 Managing the commit counter PROCEDURE commit_after (count_in IN INTEGER);Sets the break point at which a commit is performed. In other words, when the package-based counter reaches the specified number, issue a COMMIT. The default is to commit after the counter reaches 1. PROCEDURE init_counter;Initializes the PLVcmt counter referenced by the increment_and_commit program to perform incremental commits.5.6 PLVchr: Operations on Single Characters5.8 PLVddd: DDL Syntax Dump
