http://www.sinoptix.ro Oracle Developers Fri, 28 May 2010 09:24:09 +0000 http://backend.userland.com/rss092 en I don't want to blog about the ins and outs of Resource Manager and whether it's a good thing or not, but I do think this is a pretty extreme change to implement without a lot of surrounding publicity. It's a bit like the auto stats gather job that appeared ... http://feedproxy.google.com/~r/DougsOracleBlog/~3/gnpZtvLORz8/index.php I recently received this question from a PL/SQL developer: "What is the maximum size of a PL/SQL procedure?" The answer is interesting: there is not a maximum size, per se. Instead, the limitation has to do with the maximum number of DIANA nodes your program generates in the compilation process. DIANA is an ... http://www.toadworld.com/BLOGS/tabid/67/EntryID/537/Default.aspx "Invoker rights, what's that?" you may be asking. That wouldn't surprise me, greatly, though one might consider it a bit odd because the invoker rights feature of PL/SQL was added in Oracle8i - many years ago! So I will first offer a brief overview of invoker rights, why you'd use it, how ... http://www.toadworld.com/BLOGS/tabid/67/EntryID/527/Default.aspx I have certainly learned a lot over the years from other authors, and I thought I would share with you my fairly eclectic collection of favorite books (those that have informed my programming, in any case). http://www.toadworld.com/BLOGS/tabid/67/EntryID/521/Default.aspx If you've got several queries that are all using DECODE and/or CASE to map one value to another, consider creating a mapping table and joining that into your queries instead. It will make them easier to maintain, and depending on your indexes it might even speed up some queries. http://thinkoracle.blogspot.com/2010/03/decodecase-vs-mapping-tables.html Recently I've been of service to some of my colleagues who have been writing SQL Queries. Based on their feedback, I have helped them write faster-performing queries, in a shorter period of time, with fewer mistakes, and in such a way that maintenance was simpler. If you have found any ... http://thinkoracle.blogspot.com/2010/02/improving-your-sql-queries.html You learn something new every day, right? Well, I certainly do (more or less). Even about PL/SQL, about which I am sure many people think I already know everything. Far from it. In fact, I learned just last week from the PL/SQL Product Manager, Bryn Llewellyn, that his recommendation regarding cursor ... http://www.toadworld.com/Community/QuestExpertsBlogs/tabid/67/EntryID/239/Default.aspx It's good to see some more people joining in, particularly those I already know and admire. First up is Mark Bobak, who I've met at several conferences and, as you can tell from his first few posts, is likely to have some interesting technical tales to tell. http://oracledoug.com/serendipity/index.php?/archives/1419-More-Blogs.html Oracle doesn't make it terribly easy to run operating system commands from within a PL/SQL block. I suppose that's understandable, given that PL/SQL is an embedded database-oriented language. Still, developers do ask me on a regular basis about how they can do this. http://www.toadworld.com/Community/QuestExpertsBlogs/tabid/67/EntryID/228/Default.aspx As many of my readers likely know by now, I have been working for the past several years on the Quest Code Tester development effort. Code Tester is the most powerful PL/SQL test automation tool available. You describe the expected behavior of your programs and Code Tester generates your test code, ... http://www.toadworld.com/Community/QuestExpertsBlogs/tabid/67/EntryID/204/Default.aspx
