   test query:
   ```
   FROM (select 1 as key, 100 as value) src
   MAP src.*, src.key, CAST(src.key / 10 AS INT), CAST(src.key % 10 AS INT), 
src.value
   USING 'cat' AS (k, v, tkey, ten, one, tvalue);
   ```
   
   Results:
   with master:
   `1   100     1       0       1       100`
   
   with this PR:
   `1   100     1       100     1       0`
