Too many context switches may degrade performance dramatically. In order to reduce the number of these context switches we can use a feature named bulk binding. Bulk binding lets us to transfer rows between the sql engine and the plsql engine as collections. Bulk binding is available for select, insert, delete and update statements. Bulk collect is the bulk binding syntax for select statements. One of the things i usuallly come accross is that developers usually tend to use cursor for loops to process data.
DeclareCursor c1 is select column_list from table_name>;Rec1 c1%rowtype;BeginOpen c1;Loop;Fetch c1 into r1;Exit when c1%notfound;--process rows...End loop;End; Here is a simple test case to compare the performance of fetching row by row and using bulk collect to fetch all rows into a collection.

Craig Whyte, Gold Dealer + LeaveBritain.com or “The Tale of a Suave Bullionaire” I must thank, as I start, the extraordinarily diligent Billybhoy68 for his fantastic and thorough research on this and the following piece.
The raw material and much of the analysis is down to him – I have merely inserted some extra verbiage in what is, at the very least, a very ironic tale, and at worst, could be …. Well, who knows! Mr Whyte, as we all now know, was disqualified for seven years in 2000 from being a company director in the UK. The Sunday Herald yesterday raised questions about his company, Liberty Capital Ltd, registered in the British Virgin Islands, doing business in the UK during that period. Even though that is perfectly legal, it does seem to raise questions about the efficacy of the company disqualification laws, where they could be circumvented by means of an offshore company (although it is not suggested that Mr Whyte indulged in any such doubtfully legal behaviour). Billybhoy68 was also intrigued by this period in Mr Whyte’s life.

All Postings « Oracle Scratchpad. In the last article (I hope) of this series I want to look at what happens when I change the parallel distribution method on the query that I’ve been using in my previous demonstrations.
This was a query first introduced in a note on Bloom Filters (opens in a separate window) where I show two versions of a four-table parallel hash join, one using using the broadcast distribution mechanism throughout, the other using the hash distribution method. For reference you can review the table definitions and plan (with execution stats) for the serial join in this posting (also opens in a separate window). To change distribution methods from the broadcast example to the hash example I’ve simply changed a few hints in my code. Here are two sets of hints showing what I’ve done; the first is a repeat from the third article showing the broadcast example, the second shows the small change needed to get the hash example: Table queue 0 covers lines 26 – 28, we scan t1 and distribute it by hash.

Hi I have seen posts on the forums that explain how to loop thro multiple records and perform validation in a tabular database block .

Hot Rolled, USD50.00, 01-MAR-2010, 01-APR-2010 in a row, then there should be no other row that has Hot Rolled as the product and dates that overlap the dates specified in the first row.
