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))

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

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

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

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。
