Kindly help me. 回答1: A primary key does not have a direct affect on performance. But indirectly, it does. This is because when you add a primary key to a table, SQL Server

But, I was expecting the second query will have a different plan and execute more slowly as it has to select all data from contact and apply filter. It looks like I was wrong. I am wondering how this is happening? Database Server : SQL server 2005 回答1: The "query

问题 We're designing a process to archive a set of records based on different criteria like date, status, etc... Simplified set of tables: Claim, ClaimDetails, StatusHistory (tracks changes in Claim status), Comments & Files Environment: SQL Server 2005, ASP.Net MVC (.NET Framework v3.5 SP1) Claim is the main entity and it has child row(s) in the sub tables mentioned.

问题 I have a Datetime column called CreatedOn in a table. CreatedOn is also part of a non-clustered index where the order is descending. Previously in the where condition I had a condition as follows WHERE DateDiff(d,CreatedOn,GetDate()) < 180 AND ... other conditions I changed this to WHERE CreatedOn > '2012-04-04 00:00:00.000' AND ... other conditions where I am calculating the cutoff date in C# code and then putting that in the adhoc query.

问题 I have learned to use the SCOPE_IDENTITY() instead of just @@IDENTITY to get the last identity value inserted in a given scope, which can be quite useful in high-concurrency scenarios. Is there any equivalent to that function for the @@ERROR variable?
