time = 39 Ms. We can see that no performance improvement is achieved when indexes are set up, and more time is consumed, so we can continue to adjust the indexes. Then we delete all non-clustered indexes and delete the primary key, so that all indexes are deleted.Create a composite index data1 and dtat, and add the primary key: Create clustered index [c_data=dtat] on [DBO].

SQL Server backup and recovery practices I started to back up and restore the database because a project was completed right away. I checked several methods to achieve this. My goal is to back up the database on the server, so I found several methods for implementation, which are roughly divided: 1: Back up data using SQL At this time, SQL is divided into s

after the command is executed in the background. By these two points, it can be concluded that the server is black is sure, after that is a lengthy troubleshooting work. Delete the file, kill the process, check whether to set up automatic download, whether to add new users and so on. It took a while to delete the files, because an attack program was deleted and then rebuilt. It was almost like I was going to install the new system. Finally, I found a

Preface To learn any technology that is a little difficult, you must make a rational analysis of it, and then make a decisive decision-> that is, what people often say is "Seeking for profit "; although this series involves socket-related knowledge, it is a kind of state of mind that I want to share with the programmers before learning: learning is a step-by-step process, and the mentality should be adjusted at any time, keep your defense against arrogance and rashness. For example, I recen

index is deleted. Doing so causes an unnecessary rebuild of the nonclustered index. The conversion of a table from a heap table to a clustered index table always results in the rebuilding of a nonclustered index, because the content of a nonclustered indexed bookmark changes from the row number to the key of the clustered index. Do Plan Your Index defragmenting and rebuilding Based upon Usage If an index is frequently scanned, the external fragmentation of the index is important, which can have
