sql检索问题
数据表: 
 id         name         title         body         q_time   a_time   isJT 
 1               --               注册            ---               ---            ---            0 
 2               --               注册            ---               ---            ---            0 
 3               --               注册            ---               ---            ---            1 
 分别检索出isJT为0,1的 
 我的存储过程: 
 create   proc   pro_search 
 @q_title   nvarchar(200), 
 @q_body   varchar(8000) 
 as   select   *   from   question   where   (isJT= '1 'and   q_title   like    '% '+   @q_title   + '% '   or   q_body   like    '% '+   @q_body   + '% ')    
 order   by   q_time   asc 
 order   by   q_time   asc 
 --exec   pro_search    '注册 ', '注册 ' 
 读出来的结果isJT=0的也会读出来, 
 改成这样还是一样 
 create   proc   pro_search 
 @q_title   nvarchar(200), 
 @q_body   varchar(8000), 
 @isJT   int 
 as   select   *   from   question   where   (q_title   like    '% '+   @q_title   + '% '   or   q_body   like    '% '+   @q_body   + '% ')    
 order   by   q_time   asc 
 exec   pro_search    '注册 ', '注册 ', '1 ' 
 结果还是一样,isJT为0的也能读出来,帮我解决一下好吗?谢谢!
------解决方案--------------------修改下: 
 select * from question where (isJT= '1 'and q_title like  '% '+ @q_title + '% ' or q_body like  '% '+ @q_body + '% ' and isJT= '1 ')  
------解决方案--------------------and的优先级比or的大。。 
 select * from question where (isJT= '1 'and (q_title like  '% '+ @q_title + '% ' or q_body like  '% '+ @q_body + '% ' ))      
 as select * from question where ((q_title like  '% '+ @q_title + '% ' or q_body like  '% '+ @q_body + '% ') and isJT=@isJT)
