stored procedure performance tuning in sql server

Copy CodeThe code is as follows: SET ANSI_NULLS on Go SET QUOTED_IDENTIFIER ON Go CREATE PROCEDURE [dbo]. [Pagination] @Page int = 1,--current page number @PageSize int = 10--Number of record bars per page (page size) @Table nvarchar (500)--table name or view name, or even nested sql: (Select * from Tab Where id>1000) tab @Field nvarchar (800) = ' * ',--Returns the recordset field name, "," is separated by

server| Stored Procedures Extending stored procedures in SQL Server is not a lot of opportunities to use directly I summarize the ways in which I know how to use some of the useful extended stored procedures as follows:

the two: Dynamic SQL stored procedure difference Simple select 21.83 s 21.82 s 0.05% Select with WHERE clause 2.51 s 2.49 s 0.80% Select with joins 25.08 s 25.22-0.56% Select with sub-select 24.68 s 26.47-7.25% Conclusion In most cases, the difference between dynamically generated SQL statements and

necessary to explicitly delete temporary tables.At the same time, the performance problem of temporary table explicit deletion is tested in the case that the temporary table is satisfied with reuse, and it is not recommended to explicitly delete the temporary table defined in the stored procedure, regardless of whether or not it can be reused.

(functional modularization) Speaking of this, we can guess that database objects in the form of functions should be created in the database to solve this problem. But before introducing such database objects, let's look at several issues that need to be solved: We have learned to encapsulate a select statement in a view, but it can only be used for queries. If we want to perform other operations, such as adding, deleting, modifying, and deleting database tables, views cannot be used. On the oth

Stored Procedures in Transact-SQL are very similar to methods in Java. They can be called repeatedly. After the stored procedure is executed once, you can cache the statements so that the statements in the cache are directly used for the next execution. This improves the performanc
