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，单表存储过程，多表存储过程
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。

View Code6：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。
