关于’
如果字段中又有 ' '和 '的字符串,我只想查出有 '的怎么查?
------解决方案--------------------create table #t1 
 (g1 char(2), 
     g2 varchar(10))   
 insert into #t1 
 select  'a ', ' ' 'adfasdf '  
 union all select  'b ', 'b ' 'c ' 
 union all select  'c ', 'cd ' ' ' 
 union all select  'd ', 'a ' ' ' 'b '   
 select * 
 from #t1 
 where g2= 'b ' 'c '   
 select * from #t1 
 where g2 like  '% ' '% ' 
       and g2 not like  '% ' ' ' '% '     
 drop table #t1
