Top 10 steps to optimize data access in SQL Server: Part I (use indexing) - CodeProject

Let us start our optimization mission in a step-by-step process: Step 1: Apply proper indexing in the table columns in the database Well, some could argue whether implementing proper indexing should be the first step in the performance optimization process for a database. In fact, creating heavy indexing on OLTP systems might reduce the overall database performance (as most operations are update operations, updating data means updating indexes as well)

Nonetheless, I usually use Method 1 (CONVERT function) because it is compatible with different versions of SQL SERVER and also the performance is better than other two.

This is working fine but I also need to include in the result of the query days of the month where a transaction did NOT take place, those days should show as zero when counted.. The method he suggested was to use SELECT DATEADD(D, 0, DATEDIFF(D, 0, GETDATE())) I approved his method though, I finally suggested my method using function CONVERT

Personally, I like this solution (instead of the simple mode switch) because I could fire this off with a single one-line command, then restart my backup jobs as if nothing ever happened. With full recovery, you can get back all your data, even if I steal the hard drive with your data on it, but leave you the disk with the transaction log on

Since I am able to bring in one record at a time, is it possible to create a sql user function to pull in multiple records for say, an SSRS report? Reply 4-18-14 Sri says: Enjoy.. We manage our SSRS folder permissions using AD and it would be a huge benefit to be able to query AD to get a list of who has permissions to folders and reports on our SSRS

In .NET applications, you can usually format dates in data bound controls using the GUI interface, and you can also format things using the ToString() method of a true datetime value and specify all kinds of simple yet flexible formatting strings. Isn't it much easier to simply right-click on something and then enter a simple "mmm dd, yyyy" format string instead of building and parsing this manually using CONVERT and SUBSTRING parsing in T-SQL? Isn't it more flexible to do all formatting at your presentation layer so that you can just return data from your database and not worry about how it looks? Then 5 different clients can query the same stored procedure and each output those dates any way they want -- without changing any database code

How to return the date part only from a SQL Server datetime datatype - Stack Overflow

Both queries have the same execution plan, but execution plans are primarly about data access strategies and do not always reveal implicit costs involved in the CPU time taken to perform all the pieces. Making such conversions in the data tier is a huge waste of overhead on your DBMS, but more importantly, the second you do something like this, you have basically created in-memory orphaned data that I assume you will then return to a program
