Oracle Built−in Packages- P80

Oracle Built−in Packages- P80: Ah, for the good old days of Version 1.0 of PL /SQL! Life was so simple then. No stored procedures or functions and certainly no packages. You had your set of built−in functions, like SUBSTR and TO_DATE. You had the IF statement and various kinds of loops. With these tools at hand, you built your batch−processing scripts for execution in SQL*Plus, and you coded your triggers in SQL*Forms 3.0, and you went home at night content with a good day's work done. | Appendix A What s on the Companion Disk Another usability issue with SET_SESSION_LONGOPS is that any values not set in the procedure call will be set to zero. Thus if you want to increment different counter columns at different times in an application for the same row in V SESSION_LONGOPS you must keep track of all counter values and pass them all in each time the procedure is called. Adding to the cumbersome nature of the long parameter list are the extremely long names of the package and procedure themselves. You really have to want or as is more likely need to call SET_SESSION_LONGOPS in order to use it These usability issues seemed to provide an opportunity to improve ease-of-use through encapsulation. I decided to build a package called longops to offer some relief. Here is the package specification for longops Filename on companion disk longops.sql CREATE OR REPLACE PACKAGE longops IS Enhances DBMS_APPLICATION_INFO.SET_SESSION_LONGOPS by allowing individual columns to be updated without passing all parameter values.
