If you are in charge of a SQL Server-based project or you have just been in touch with SQL Server, you may have to face some database performance problems, this article will provide you with some useful guidance (most of which can also be used for other DBMS ).Here, I am not going to introduce the tips for using
Some people have said that it is insecure to remotely connect to SQL Server 1433 through port 2000 of the external service provided by SQL Server. Indeed, there are many tools on the Internet to catch port 1433, then we can find a way to modify the default port number 1433,

The purpose of this article is to say that during performance testing, we must ensure that the bottleneck does not occur in our own test scripts and test tools.

design of merge replication allows you to make changes to the data at the Publisher and Subscriber side from the outset. Merge replication also allows you to disconnect without connecting users during the day. The user will be synced at night after reconnecting. If a row is updated at the same time in two different places, a conflict occurs. Merge replication has several built-in options to resolve these conflicts. set up transactional replication This section is a step-by-step guide to settin

Some overhead will be required here and the process will slow down when decoding. If the network package is out of your control, this is a good practice.

Today, we mainly describe the correct implementation of connecting SQL Server databases to the DB2 connection Server. We all know that the interconnection between different database platforms is generally called a heterogeneous service, currently, different databases can achieve such Heterogeneous Interconnection, but the specific implementation technologies of d

When using SQL Server, the most common problem you encounter is that the connection fails. Generally, there are two ways to connect to SQL Server. One is to use the client tools provided by SQL
. The ENCRYPTION keyword protects SQL Server from being exposed in the process. As a result, if ENCRYPTION is activated, the system storage process sp_helptext will be ignored, and the storage process will be stored in the text of the process created by the user. If you do not want ENCRYPTION, you can use alter procedure to ignore the with encryption clause to recreate a process.To enable encryption. Both u
