The dual-host approach means that two different services are in the primary standby state (that is, the Active-standby and Standby-active states) on two servers respectively.We are mainly using the SQL Server 2005 subscription repl
Through the menu below, we can generate scripts for every object in the database we selected in SQL Server Management studio. This allows us to manage database versions, and the Database Upgrade documentation is very convenient. Many parameters can be selected during script generation. reasonable configuration of these parameters makes it easy for us to generate
You can use the "generate SQL script" tool that comes with SQL Server 2000 to generate SQL scripts for creating tables, views, and stored procedures. So can we generate SQL scripts for the data in the table and automatically impor
SQL Server has powerful replication capabilities, in addition to synchronizing data and database objects from one database to another and accurately distributing them. SQL Server replication is divided into three kinds, the follow

Application Scenario:
Many complex update queries are time-consuming in a large database. In order to avoid the user waiting for a long time, those time-consuming operations can be performed asynchronously, immediately return the execution information to the user, while performing operations in the database background, wait until the completion of the data table update.
