存储过程中的 LIKE '%@XXXX%' 模糊搜索问题，请大家帮我看看怎么回事！
ALTER   PROCEDURE   dbo.search_result_cominfo   @add_city   int,@com_name   varchar(50)

AS
SELECT   userid,   user_company,   user_realname,   user_tel,   user_mobi,   user_fax FROM   User_Table
WHERE   (user_city   =   @add_city)   AND   (user_company   LIKE   '%@com_name% ')
RETURN

怎么都搜索不到东西，数据库有符合条件的记录呀。请大家帮我看看怎么回事！

------解决方案--------------------------------------------------------
要动态执行sql
转换成字符串
------解决方案--------------------------------------------------------
LIKE '%@com_name% '==> LIKE '% ' + @com_name + '% '
------解决方案--------------------------------------------------------
user_company LIKE '% '+@com_name+ '% '
------解决方案--------------------------------------------------------
user_company LIKE '% ' + @com_name + '% '
------解决方案--------------------------------------------------------
LIKE '%@com_name% '

==>

LIKE '% ' + @com_name + '% '


------解决方案--------------------------------------------------------
LIKE '%@com_name% '
改成
like '% ' + @com_name+ '% '
------解决方案--------------------------------------------------------
ALTER PROCEDURE dbo.search_result_cominfo @add_city int,@com_name varchar(50)

AS
SELECT userid, user_company, user_realname, user_tel, user_mobi, user_fax FROM User_Table
WHERE (user_city = @add_city) AND (user_company LIKE '% ' + @com_name+ '% ')
RETURN
就可以了 因为 '%@com_name% '会被错误的当成一整个字符串
