sql server maintenance cleanup task

when using SQL Server High availability features, for example,the XenDesktop site database uses the full transaction logging mode to run database mirroring. transaction logs that run through the full transaction logging mode grow too large until the database space is filled or the transaction log space size is filled. If the transaction log files are not monitored,the configuration log file for

Label:--Maintenance Database---- Trigger -- --Overview：Note:a trigger is a special type of stored procedure，used to enforce business rules。 On invocation, triggers cannot be called directly by the user through T-SQL statements, as stored procedures do, but require the execution of INSERT, UPDATE, delete events that occur on the database to fire the automatic execution of the trigger. Therefore, when creatin

non-overwrite update, it will cause the movement of the data rows during the page splitting process:(1) The move of the clustered index has no effect on the nonclustered index, because the key value of the clustered index is stored in the nonclustered index, and the split does not change the key value;(2) The data page in the heap table splits, leaving a forward pointer at the original record to tell the nonclustered index where to find the new record;So the movement of data rows does not cost

, and the request involves using a partitioned table, the optimizer can optimize the request to find the appropriate data only on the appropriate partition. ( more about the partition table, you can refer to our site published in the "Understanding of the Section table" series of articles )Although it is said that we are talking about distributed partitioned views, in fact, in SQL Server 2005 (and later ver

In the application system, especially in the online transaction processing system, the data query and processing speed has become the standard to measure the success or failure of the application system. And the use of index to speed up data processing has become the majority of database users to accept the optimization method. Based on good database design, efficient use of indexes is the basis for SQL Server
