实例操作 教你玩转SQL Server存储过程（3）--实例讲解

实例1：只返回单一记录集的存储过程。　　表银行存款表（bankMoney）的内容如下IduserIDSexMoney001Zhangsan男30002Wangwu男50003Zhangsan男40要求1：查询表bankMoney的内容的存储过程create procedure sp_query_bankMoneyasselect * from bankMoneygoexec sp_query_bankMoney注* 在使用过程中只需要把中的SQL语句替换为存储过程名，就可以了很方便吧！　　实例2（向存储过程中传递参数）：加入一笔记录到表bankMoney，并查询此表中userID= Zhangsan的所有存款的总金额。Create proc insert_bank @param1 char(10),@param2 varchar(20),@param3 varchar(20),@param4 int,@param5 int outputwith encryption ---------加密asinsert bankMoney (id,userID,sex,Money)Values(@param1,@param2,@param3, @param4)select @param5=sum(Money) from bankMoney where userID='Zhangsan'go在SQL Server查询分析器中执行该存储过程的方法是：declare @total_price intexec insert_bank '004','Zhangsan','男',100,@total_price outputprint '总余额为'+convert(varchar,@total_price)go在这里再啰嗦一下存储过程的3种传回值（方便正在看这个例子的朋友不用再去查看语法内容）:1.以Return传回整数2.以output格式传回参数3.Recordset传回值的区别:output和return都可在批次程式中用变量接收,而recordset则传回到执行批次的客户端中。实例3：使用带有复杂 SELECT 语句的简单过程　　下面的存储过程从四个表的联接中返回所有作者（提供了姓名）、出版的书籍以及出版社。该存储过程不使用任何参数。　　USE pubsIF EXISTS (SELECT name FROM sysobjects WHERE name = 'au_info_all' AND type = 'P') DROP PROCEDURE au_info_allGOCREATE PROCEDURE au_info_allASSELECT au_lname, au_fname, title, pub_name FROM authors a INNER JOIN titleauthor ta ON a.au_id = ta.au_id INNER JOIN titles t ON t.title_id = ta.title_id INNER JOIN publishers p ON t.pub_id = p.pub_idGO　　au_info_all 存储过程可以通过以下方法执行：　　EXECUTE au_info_all-- OrEXEC au_info_all　　如果该过程是批处理中的第一条语句，则可使用：　　au_info_all　　实例4：使用带有参数的简单过程　　CREATE PROCEDURE au_info @lastname varchar(40), @firstname varchar(20)ASSELECT au_lname, au_fname, title, pub_name FROM authors a INNER JOIN titleauthor ta ON a.au_id = ta.au_id INNER JOIN titles t ON t.title_id = ta.title_id INNER JOIN publishers p ON t.pub_id = p.pub_id WHERE au_fname = @firstname AND au_lname = @lastnameGO　　au_info 存储过程可以通过以下方法执行：　　EXECUTE au_info 'Dull', 'Ann'-- OrEXECUTE au_info @lastname = 'Dull', @firstname = 'Ann'-- OrEXECUTE au_info @firstname = 'Ann', @lastname = 'Dull'-- OrEXEC au_info 'Dull', 'Ann'-- OrEXEC au_info @lastname = 'Dull', @firstname = 'Ann'-- OrEXEC au_info @firstname = 'Ann', @lastname = 'Dull'　　如果该过程是批处理中的第一条语句，则可使用：　　au_info 'Dull', 'Ann'-- Orau_info @lastname = 'Dull', @firstname = 'Ann'-- Orau_info @firstname = 'Ann', @lastname = 'Dull'实例5：使用带有通配符参数的简单过程CREATE PROCEDURE au_info2@lastname varchar(30) = 'D%',@firstname varchar(18) = '%'ASSELECT au_lname, au_fname, title, pub_nameFROM authors a INNER JOIN titleauthor ta ON a.au_id = ta.au_id INNER JOIN titles t ON t.title_id = ta.title_id INNER JOIN publishers p ON t.pub_id = p.pub_idWHERE au_fname LIKE @firstname AND au_lname LIKE @lastnameGO　　au_info2 存储过程可以用多种组合执行。下面只列出了部分组合：　　EXECUTE au_info2-- OrEXECUTE au_info2 'Wh%'-- OrEXECUTE au_info2 @firstname = 'A%'-- OrEXECUTE au_info2 '[CK]ars[OE]n'-- OrEXECUTE au_info2 'Hunter', 'Sheryl'-- OrEXECUTE au_info2 'H%', 'S%'　　= 'proc2
