一个不知道是难还是不难的问题``麻烦高手了```
declare   cro_fastread   cursor   scroll 
             for      后面跟参数可以吗`??   
 本来是: 
             declare   cro_fastread   cursor   scroll 
             for            select   Pr_id   from   Product   where   tint_level=0   and   tint_tableid=@tint_tableid   order   by   int_id   desc   
 可是现在我想放进一个条件``@xl,里面是一段的字符串``就@xl= "id=1   and   name= 'aaa ' "   
 有人帮助下吗`> > ?? 
------解决方案--------------------可以使用动态游标,因为游标可以使用EXEC()动态生成然后引用: 
 declare @sql varchar(8000),@x1 varchar(100) 
 ----设置参数 
 set @x1 =  'id=1 and name= ' 'aaa ' ' ' 
 ----定义动态游标字符串 
 set @sql =  ' 
 declare cro_fastread cursor scroll 
 for select Pr_id from Product where tint_level=0 and tint_tableid=@tint_tableid  ' +  
 CASE WHEN isnull(@x1, ' ') =  ' ' THEN  ' ' ELSE  ' and  ' + @x1 END +   /*@x1参数*/ 
  '  order by int_id desc ' 
 ----创建动态游标 
 EXEC(@sql) 
 ----打开游标 
 open cro_fastread 
 fetch next from cro_fastread into ... 
 ----循环游标 
 while @@fetch_status = 0 
 begin 
     ... 
     fetch next from cro_fastread into ... 
 end 
 ----关闭游标 
 close cro_fastread 
 ----释放游标资源 
 deallocate cro_fastread
