  • sqlserver存储过程里传字段、传字符串,并返回DataTable、字符串,存储过程调用存储过程。

               经常需要查一些信息,  想写视图来返回数据以提高效率,但是用试视图不能传参,只好想到改存储过程。记录一下语法,方便以后做项目时候想不起来了用。

     1:传字段返回datatable

     2: 传字段回一串字符

     3: 传字符串返回datable

     4:存储过程调用存储过程

     5:存储过程里写分页

     6:sqlserver里检验写好的存储过程遇到的问题(分页返回table)段2 为解决办法。

    --加半个小时
    (select dateadd(MINUTE,30,GETDATE() ))--UnLockTime 往后加半个小时 CONVERT(varchar(100), @UnLockTime, 20)

    --转成可以拼接字符串的格式
    set @strOutput='0~由于您最近输错5次密码已被锁定,请在'+CONVERT(varchar(100), @UnLockTime, 20) +'之后再尝试登录~'+CAST(@Id AS NVARCHAR(10))

    5:存储过程里写分页

               调用:

    USE [eSystem]
    GO

    DECLARE @return_value int

    EXEC @return_value = [dbo].[xsp_ination]
    @tblName = N't_FormOperationRecord',
    @strGetFields = N'Id,UploadDownloadId ,Operationtime,OptName',
    @fldName = N'Id',
    @PageSize = 10,
    @PageIndex = 220,
    @OrderType = 1

    SELECT 'Return Value' = @return_value

    GO

    sql = "EXEC [dbo].[xsp_ination] "tblNEWS","*","id",40," + pindex.ToString() + ",1,"iType=" + type.ToString(); 

    SqlDataReader sr = ExecuteReader(sql);  
    while (sr.Read())  
    {  
       ...  
    }  
    sr.Close();

    6:检验写好的存储过程查不出结果集(分页返回table),段2 为解决办法。

         写了一个分页模板的存储过程见下段代码,在sqlserver工具,选定执行的存储过程,右键execute,然后就输入各个参数,执行完毕啥都没有,语法如段1, 然后以为存储过程写的有问题,换了很多种方法,结果集都为空,然后搜到了一个别人的检验的语法,如段2,就出来了。仔细看了,段1  @return_value 返回整个查询结果,可是为什么 自定义的是int  型 的,去掉了直接赋参执行存储过程还是不出数据。       段二EXEC 直接执行存储过程就返回整个结果了。  找到了以前写的单独的存储过程返回table 的如段3,看到里面结束时候也没有select,但是为什么直接在工具里execute就能出结果, 一时没有想明白是什么原因,要去写其他代码了,有时间了在回来整理这个问题。
