With the upcoming SQL Server 2005 extended support deadline fast approaching, they want to understand how to help you migrate to a modern, supported version of SQL Server, and how to provide support and upgrades in future. By automating the process of gathering and storing appropriate counters, you can routinely check a range of devices quickly using visual tools such as PerfMon

Which is more efficient, using an EXISTS check or a SELECT COUNT(*)? Answer: Using the T-SQL EXISTS keyword to perform an existence check is almost always faster than using COUNT(*)

SQL Server Forums - if exists drop index

In all of the above examples, any table with that index name will show it as "existing."You need to be sure to include your table name with your index check

I prefer to use the system for this and simply get a count because you can assign the column count to a variable at the top of a query and then choose to proceed or not based on that. The trick is not to use the table alias for such columns (which is a frowned-upon practice in most situations, but in this case omitting the table alias helps you to resolve the issue)

*l.value3 and r.value2 are not comparable (although there might exist a correlation) *l.value3 is nullable (which I think is not a big deal because the condition is out of the NOT IN clause). So with the join you would want when r.value is not null For Each r.value ALL r.value2 1 (this part is hard to explain: just remember that r.value can have multiple r.value2 associated to it and we want all of them to be different from 1) So now I am stuck searching for a way to express existential and universal conditions

Without ISOLATION LEVEL SERIALIZABLE, the default isolation level (READ COMMITTED) would not lock the table at read time, so between select and update, somebody would still be able to insert.

SQL Server T-SQL Tuning - NOT IN and NOT Exists - SQL Server Performance

Much informative!! Phil Reply January 16, 2013 at 8:20 am It would be nice to see some test results which back up your assertions, using sample data with hundreds of thousands of rows. This can however have a major impact on performance as the Not IN command requires a check to be made on each record individually resulting in a strain on resources and can also lead to locks particularly when updating or deleting a large volume of data

If data is huge, if there are any Non-Clustered indexes that are not build on primary key or unique key, then disable those indexes, loading will be much faster. How can I fix? I have SQL Server 2008 and Visual Studio 2008 and am trying to automatically insert new records into a child table based on new inserts into its parent table

Uh! I almost felt like going back in time some ten years when I was writing kernel drivers for Windows :) This is excellent participation from experts like Marko and Brian. Is it better write a function Drop table and and pass table name as parameter to do this? In my opinion, I think it is expensive to go to a function from a stored procedure just to drop a table
