how to optimize stored procedures in sql server

This article describes how to use Java to invoke SQL Server stored procedures, detailed 5 different kinds of storage. Please see below for details 1, the use of stored procedures with no parameters When using the JDBC driver to invoke stored procedures without parameters,

SQL Server quickly searches for stored procedures (SQL statements) of a field. The Code is as follows: SELECT obj. name: Name of the stored procedure, SC. TEXT Stored Procedure content FROM syscomments scINNER JOIN sysobjects obj ON SC. id = obj. IDWHERE SC. text like '% content to be queried %' The above section de

There are two basic types of system stored procedure: System stored Procedure: theT-SQL language, provided in the master database, mostly using the sp_ prefix, when used in other databases, do not need to specify The Master database as part of their name, typically applied to administrative tasks System extended Stored Procedure: unmanaged code written (mainly C + +), provided by the DLL, mostly using the xp_ prefix, Used t

Using SQL Server stored procedures can greatly improve the running speed of programs, simplifying the difficulty of programming maintenance, has been widely used. The stored procedure is actually a collection of Transact-SQL statements that are saved to accept and return user-supplied parameters. can create a proce

the following statement: EXEC spname 　　 EXEC ' Ruyi knife Wolf ' The output results are as follows: 　　 3.

You can create a procedure for permanent use, or for temporary use in a session (local temporary procedures), or for temporary use in all sessions (global temporary procedures). You can also create stored procedures that run automatically when Microsoft SQL Server starts. Gr

SQL Server provides a wealth of system stored procedures to help us manage our databases and develop them. Share today introduction Some common database extended stored procedures xp_cmdshell This is familiar to everyone, and you can use xp_cmdshell to execute DOC commands when you connect to

sounds like creating a primary key in a data table, when you create a primary key in a data table, a clustered index tree is created, and all data pages contain all rows in the table are physically sorted by their primary key values in the file system, each data page contains the primary keys of rows for sorting. Therefore, when querying rows in a table, the database server first finds the compliant data header and uses the clustered index tree, then

Most of the time, our server performance bottleneck is when querying the database, so the caching of the database is very important, then there is a way to implement the SQL Server database cache, when the datasheet is not updated, read from the cache, when there is an update, to read from the datasheet, The answer is yes, so we can cache some of the most common
