When the database is troubleshooting according to regulations, you need to view each of the 50 tables in the database to ensure that all fields that are expected to be the default value are assigned the default value. It can be imagined that this is a daunting task. Is there a better way to view this schema than opening every table in the SQL server administration suite?By querying three system tables in an

it is to increase I/O.2. Vertical and horizontal partition table, reduce the size of the table (Sp_spaceuse)3. Upgrading hardware4, according to the query criteria, index, optimize the index, optimize access mode, limit the data volume of the result set. Note that the fill factor is appropriate (preferably using the default value of 0). The index should be as small as possible, using a Lie Jian index with a small number of bytes (refer to the creatio

:A. Needs to be queried from the database: Totalrecords. "SELECT COUNT (*) from TableName"B. The most basic needs of user-provided: PageSize and Pagenow. (Personally think this is the premise of pagination algorithm)C. Derived from other variables: TotalPages, Beginrow and Endrow. (it needs to be calculated that Beginrow and endrow are required for paging queries, TotalPages is the information that the page needs to provide). Specific formula for calculation: Totalpages:if ((totalrecord

index controls the order of data rows based on key-value fields. Because SQL SERVER sorts data rows by the key-value fields of clustered indexes, when you need to sort certain fields, use these fields as the key-value of clustered indexes, creating a clustered index will greatly improve the query performance. Because the data has been sorted in the order of the

The SQL Server compact product group published a blog article about how to improve the query performance of the SQL Server compact database. It is comprehensive and authoritative. We suggest you take a look. In fact, the SQL

The most obvious feature of SQL differs from other programming languages is the order in which the code is processed. In a large number programming language, code is processed in encoded order, but in the SQL language, the first processed clause is the FROM clause, although the SELECT statement first appears, but is almost always finally processed.Each step produces a virtual table that is used as input to

Deadlock) refers to the state in which processes are permanently blocked. SQL can detect deadlocks and terminate a transaction to intervene in the deadlock State. A typical example of A deadlock between two processes is: Obtain lock A in process T1 and apply for lock B; obtain lock B in process T2 and apply for lock A. Here we will demonstrate this situation: 1. Create a Database named InvDB. 2. Execute the following script to create the person table

There are many reasons for slow query speed in SQL Server databases. The following are common causes: 1. No index or no index is used (this is the most common problem of slow query and is a defect in programming) 2. Low I/O throughput, resulting in a bottleneck effect. 3. the query
