![]() If you want to check if a perticular stored procedure executed recently SELECTĪnd (sysobject.object_id = object_id('schemaname. Right-click on the row and choose Edit selected row. Effortlessly edit table data Changing data in any cell is easy with SQLPro Studio. The table underneath will then reflect the result for each query separately. This will give you the list of the procedures recently executed. Just type in the query in the text editor as usual and click Run all. INNER JOIN sys.objects sysobject ON sysobject.object_id = stats.object_id But the life time of the row has a limit, The moment the execution plan is removed from the cache the entry will disappear. Sys.dm_exec_procedure_stats contains the information about the execution functions, constraints and Procedures etc. When a plan is removed from the cache, the corresponding rows are eliminated from this view. The view contains one row per query statement within the cached plan, and the lifetime of the rows are tied to the plan itself. When a stored procedure is removed from the cache, the corresponding row is eliminated from this view. The view contains one row per stored procedure, and the lifetime of the row is as long as the stored procedure remains cached. Returns aggregate performance statistics for cached stored procedures. The following excerpts are from Books Online for the given dm views… If you were to use such a thing to determine which SPs are candidates for being dropped, you could be in for a world of hurt when you delete SPs that were used just minutes ago. They only work against what is in cache and the lifetime of what is in cache can be measured in minutes. Expand Stored Procedures, right-click the procedure and then click View Dependencies. Expand Databases, expand the database in which the procedure belongs, and then expand Programmability. ,Filename = N'D:\DBSnapshots\DBSnapshotTest2.Oh, be careful now! All that glitters is NOT gold! All of the “stats” dm views and functions have a problem for this type of thing. In Object Explorer, connect to an instance of Database Engine and then expand that instance. The Snapshot should contain the old values*/ĬREATE DATABASE DBSnapshotTest_Snapshot02 ON ( *Verify that you can Select from the Snapshot This can be beneficial in many ways because you can compare data before and after changes have been made to help you test how your changes affected the data. Snapshots also have another benefit in that you can have your users read from the snapshot to see how data looked when the snapshot was taken. ![]() Microsoft has an excellent article if you would like more details on this feature: Basically what happens is those original pages that were stored in the snapshot replace the pages that were changed. When I say, your database will look like it was when the snapshot was taken, that means all data and even objects. Optionally, you can rollback to your snapshot and force your database to look like it was when the snapshot was taken. If you drop the snapshot, then the changes are kept in the database. All the original data pages that have changed on your database are stored in a snapshot file. This example loosely resembles what happens with Database Snapshots. The easiest thing to do is to just take a copy of your Snapshot and replace the working draft. You edit your draft document and save it but the next day you realize that you don’t like any of those changes you made and there is no way for you to remember all the changes you made to reverse them. So what do you do? You probably copy that document somewhere else creating a Snapshot of it. (The ODBC driver will then reformat the call for you to match the given database. ![]() You realize later that you may want to make some adjustments, but the software you use does not support some fancy change tracking features. To call a stored procedure right now, pass the call to the execute method using either a format your database recognizes or using the ODBC call escape format. ![]() You are satisfied with that draft letter and so you save it on your computer. Imagine that you are writing a letter to someone using some word processor application of your choice. After running updates to data, comparing data before and after the updates.īefore I get to the good stuff, let me explain what Database Snapshots are and how they work exactly. SQL Server has the ability to cache the execution plan for. Easily undo data and object changes going back to how things were originally.Ģ. One of the biggest performance gains built into SQL Server is the stored. What I want to accomplish in this post is show you two ways that Snapshots can help you when you are doing Testing and QA:ġ. This post is intended to show an easy way to use Database Snapshots in order to test new code or change data and revert changes back quickly and easily. As database professionals we are always looking to improve the quality of our code and data. If you’re married to your Database, that’s a different story all together and I don’t think I could help you. First let’s get things straight, this post is not an encouragement for anyone to spend more time with his/her Database or with Database Snapshots for that matter.
