    I tried two solutions:
   
   ```rust
           let sql = concat!(
               "SELECT b, d ",
               "FROM t1 JOIN t2 ON t1.a = t2.a ",
               "ORDER BY b ASC ",
               "LIMIT 3"
           );
   
           let sql = concat!(
               "SELECT t1.a as a, b, d ",
               "FROM t1 JOIN t2 ON t1.a = t2.a ",
               "ORDER BY b ASC ",
               "LIMIT 3"
           );
   ```
   
   But I still got the same error.
   
   ```shell
   Schema contains duplicate unqualified field name \'a\'")
   thread 'tests::simple_join' panicked at 'assertion failed: `(left == right)`
     left: `1`,
    right: `0`: the test returned a termination value with a non-zero status code (1) which indicates a failure'
   ```
