Label:SQL Server-constraint one, the classification of constraintsIn SQL Server, there are 3 different kinds of constraints. 1. Entity constraints Entity constraints are about rows, such as when a row appears with values that are not allowed to appear on other rows, such as a primary key. 2. Domain constraints Domain constraints are about columns, and for all row

First, the basic concept of indexed viewsAn indexed view is actually a view that "materialized" a set of unique values into a clustered index, which is materialized almost as a table, and its data is stored in one copy (it consumes hard disk space, but the query is fast, for example, you can set count (), sum () in an indexed view). The advantage is that it provides a very quick way to find the information behind the view. After the first index (a clustered index that must be for a unique set of

, you can begin using it quite easily. All of the operations passed med in the example use one or more of the following objects: SQLDMO. Application SQLDMO. SQLServer SQLDMO. Database SQLDMO. NameList There are a multitude of objects available for actions such as backups and restores, but for the purpose of this article I decided to keep it simple to forget you into the world of SQLDMO. Listing the available SQL Servers on your network is quite

)(This is mainly considering the improvement of the previous table) index design Guidelines• You should create indexes on columns that are used frequently in the WHERE clause• You should create indexes on columns that are frequently used for joining tables• You should create an index on the columns that are used frequently in the ORDER by clause• You should not create indexes on small tables (tables that use only a few pages) because a full table scan operation may be faster than a query execute
