Oracle supports the use of Java in the database as a non-proprietary, powerful programming language. Coupling triggers and Java stored procedures can satisfy platform-independent database programming policies and often complicated application-related DML processing requirements. Here's an example of a trigger that calls a Java stored procedure. >> CLICK for the full tip... http://searchdatabase.techtarget.com/tip/1,289483,sid13_gci772163,00.html =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= WHY USE STORED PROCEDURES? | by Parthasarathy Mandayam Stored procedures offer several distinct advantages over embedding queries in your Graphical User Interface (GUI).

Until now, authoritative coverage of the techniques available to meet these challenges and reap their benefits -- both programming and career benefits -- didn't exist. "Understanding SQL and Java Together" examines all the standards for combining SQL and Java. It shows you exactly how to use their features to write efficient and effective code supporting Java access to SQL data in a variety of ways. You'll gain a thorough understanding of the relationship between SQL and Java, which will allow you to write static and dynamic SQL programs in Java, merge Java code with SQL databases and SQL code, and use other data management techniques wherever appropriate. http://www.digitalguru.com/DigitalGuru/product_detail.asp?catalog_name=Books&category_name=&product_id=1558605622&partner_id=77 =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= WIN A TOSHIBA DVD PLAYER! | Submit your Tip Share your knowledge, help your peers, and compete to win a $200 DVD player.
