SQL Server编写存储过程小工具 功能:为给定表创建Update存储过程 语法: sp_GenUpdate <Table Name>,<Primary Key>,<Stored Procedure Name> 以northwind 数据库为例 sp_GenUpdate \\\'Employees\\\',\\\'EmployeeID\\\',\\\'UPD_Employees\\\' 注释:假如您在Master系统数据库中创建该过程,那您就可以在您服务器上所有的数据库中使用该过程。 ===========================================================*/ CREATE procedure sp_GenUpdate @TableName varchar(130), @PrimaryKey varchar(130), @ProcedureName varchar(130) as set nocount on declare @maxcol int, @TableID int \\\'knowsky.com set @TableID = object_id(@TableName) select @MaxCol = max(colorder) from syscolumns where id = @TableID select \\\'Create Procedure \\\' + rtrim(@ProcedureName) as type,0 as colorder into #TempProc union select convert(char(35),\\\'@\\\' + syscolumns.name) + rtrim(systypes.name) + case when rtrim(systypes.name) in (\\\'binary\\\',\\\'char\\\',\\\'nchar\\\',\\\'nvarchar\\\',\\\'varbinary\\\',\\\'varchar\\\') then \\\'(\\\' + rtrim(convert(char(4),syscolumns.length)) + \\\')\\\' when rtrim(systypes.name) not in (\\\'binary\\\',\\\'char\\\',\\\'nchar\\\',\\\'nvarchar\\\',\\\'varbinary\\\',\\\'varchar\\\') then \\\' \\\' end + case when colorder < @maxcol then \\\',\\\' when colorder = @maxcol then \\\' \\\' end as type, colorder from syscolumns join systypes on syscolumns.xtype = systypes.xtype where id = @TableID and systypes.name <> \\\'sysname\\\' union select \\\'AS\\\',@maxcol + 1 as colorder union select \\\'UPDATE \\\' + @TableName,@maxcol + 2 as colorder union select \\\'SET\\\',@maxcol + 3 as colorder union select syscolumns.name + \\\' = @\\\' + syscolumns.name + case when colorder < @maxcol then \\\',\\\' when colorder = @maxcol then \\\' \\\' end as type, colorder + @maxcol + 3 as colorder from syscolumns join systypes on syscolumns.xtype = systypes.xtype where id = @TableID and syscolumns.name <> @PrimaryKey and systypes.name <> \\\'sysname\\\' union select \\\'WHERE \\\' + @PrimaryKey + \\\' = @\\\' + @PrimaryKey,(2 * @maxcol) + 4 as colorder order by colorder select type from #tempproc order by colorder drop table #tempproc /*=======源程序结束=========*/ 返回类别: 教程 上一教程: SQL SERVER在JAVA中的应用 下一教程: ADO之COMMAND对象全解 您可以阅读与"SQL SERVER编写存储过程小工具(三)"相关的教程: · SQL SERVER编写存储过程小工具(一) · SQL SERVER编写存储过程小工具(二) · 编写安全的SQL SERVER扩展存储过程 · 修改SQL SERVER内置存储过程 · SQL SERVER存储过程/函数加/解密 |
