SQL Server查询区分大小写

默认情况下，select语句是不区分大小写的，语句形式为：

               string strSelect = "select UserName from UserInfor where

                        UserName [email protected] and

                        UserPWD  [email protected]";

  string strSelect = "select UserName from UserInfor where

                        UserName [email protected] and

                        UserPWD  [email protected]";

如果需要区分大小写，则需要写成：

         string strSelect = "select UserName from UserInfor where

                        UserName collate [email protected] and

                        UserPWD collate [email protected]";

 string strSelect = "select UserName from UserInfor where 

                        UserName collate [email protected] and 

                        UserPWD collate [email protected]";
