I. BACKGROUND When you build SQL Server replication, if the network environment is within the LAN, through the host name can be achieved, but if it is across the network segment, across the computer room to build replication when you need to pay attention to, because SQL Server replication does not support through IP

How to interact with XML in SQL ServerXML can be said to be a flexible form of database performance. During database development XML is required, especially for data exchange. In SQL Server 2005, XML has become a popular data type

Because of business splitting, the database is split into two roles: Summary database (Master, head node database), Child node Database (Compute node, compute child node database) In this way, the design to the child node access to the head node database of a summary table, the records of such tables generally in a few, to hundreds of thousands of rows or so, currently suitable for cross-library queries.Cross-Library queries are curr

One, copy the database one table to another database (same server) SELECT * into table 1 from table 2--Copy table 2 If you only copy the structure without copying the content or just a column, just add the Where condition. Example:(Copy the Syslog table from database aimmanagedb to database imcdb) Second, copy a table from one database to another (cross-server)

You often encounter situations where you need to insert bulk data into SQL Server and then further process the data in a stored procedure. The stored procedure does not have a parameter type such as an array or a list, and the XML type solves the problem properly. However, SQL Server2005 support for standard
