求SQL Server存储过程：关键字匹配多个字段

shenzongyi123 2010-09-17 09:51:10
是这样的，我想通过输入一个关键字，在一个表里这个关键字可以模糊匹配多个字段，并将受影响的行数返回！
这是我写的测试代码：
CREATE PROCEDURE sp_getTotalRecordsByKeyWords

	@keyWords varchar(50)

AS

SELECT count(*) AS total,

	  cast(b.bookID as varchar(30))

	  + cast(b.typename as varchar(30))

	  + cast(b.bookname as varchar(50)) 

	  + cast(b.publish as varchar(20)) 

      + cast(b.author as varchar(30)) AS keyWords  

FROM bookinfo b

WHERE b.keyWords like '%' +@keyWords + '%';

GO

错误消息：
消息 207，级别 16，状态 1，过程 sp_getTotalRecordsByKeyWords，第 11 行
列名 'keyWords' 无效

提示什么？都说了少了group by语句了。

在Where子句后面加

CREATE PROCEDURE sp_getTotalRecordsByKeyWords
@keyWords varchar(50)
AS
SELECT count(*) AS total,
cast(b.bookID as varchar(30))
+ cast(b.typename as varchar(30))
+ cast(b.bookname as varchar(50))
+ cast(b.publish as varchar(20))
+ cast(b.author as varchar(30)) AS keyWords
FROM bookinfo b
WHERE cast(b.bookID as varchar(30))
+ cast(b.typename as varchar(30))
+ cast(b.bookname as varchar(50))
+ cast(b.publish as varchar(20))
+ cast(b.author as varchar(30)) like '%' +@keyWords + '%'
group by cast(b.bookID as varchar(30))
+ cast(b.typename as varchar(30))
+ cast(b.bookname as varchar(50))
+ cast(b.publish as varchar(20))
+ cast(b.author as varchar(30))



好别扭啊！

keyWords是那几个字段连接后的别名，不知道我的写法有问题，这方面了还不是很清楚！麻烦哪位告诉我下，该如何实现该功能

在一个表里这个关键字可以模糊匹配多个字段

可能你想要模糊查询，如果用到动态字段就用动态语句，估计你字段都定好了。所以
col1 like '%' +@keyWords + '%'
or col2 like '%' +@keyWords + '%'
or col3 like '%' +@keyWords + '%'

你的写法有问题吧！

没有分组语句，怎么用count这个聚合函数？

group by

-- 错误已经很明显啦：列名 'keyWords' 无效！
-- 意思是你的列名写错了嘛！表中不存在　名为 keyWords 的字段名！

额……问题终于解决了，好像是total和keyWords别名的原因。
SQL别名问题参考：http://weichongkun.blog.163.com/blog/static/71220498200881973344263/
这是我修改后的代码：
CREATE PROCEDURE sp_getTotalRecordsByKeyWords

    @keyWords varchar(50)

AS

SELECT count(*)  

FROM bookinfo b

WHERE cast(b.bookID as varchar(30))

      + cast(b.typename as varchar(30))

      + cast(b.bookname as varchar(50)) 

      + cast(b.publish as varchar(20)) 

      + cast(b.author as varchar(30)) like '%' +@keyWords + '%';

GO



exec sp_getTotalRecordsByKeyWords 'j'

返回无名列：结果集为2

似乎也不对，要不这样
CREATE PROCEDURE sp_getTotalRecordsByKeyWords

    @keyWords varchar(50), @count int output

AS

SELECT  cast(b.bookID as varchar(30))

      + cast(b.typename as varchar(30))

      + cast(b.bookname as varchar(50)) 

      + cast(b.publish as varchar(20)) 

      + cast(b.author as varchar(30)) AS keyWords  

FROM bookinfo b

WHERE cast(b.bookID as varchar(30))

      + cast(b.typename as varchar(30))

      + cast(b.bookname as varchar(50)) 

      + cast(b.publish as varchar(20)) 

      + cast(b.author as varchar(30)) like '%' +@keyWords + '%'

SET @count = @@ROWCOUNT

GO

SQL查询字段被包含语句
说到SQL的模糊查询，最先想到的，应该就是like关键字。当我们需要查询包含某个特定字段的数据时，往往会使用 ‘%关键字%’ 查询的方式。具体代码示例大家参考下本
