   @qiuchenjian Basically when you provide `sum` and `count` we no need provide `avg` during the creation of datamap. So the following test case should work.
   ```
   sql("create datamap test_table_mv using 'mv' as select sum(height),count(age),name from test_table group by name")
   ```
   On the above datamap following query should hitthat datamap.
   ```
   sql("select avg(age),name from test_table group by name")
   ```
   The actual intention of the code was to derive `avg` from `sum` and `count` columns. So we no need to provide `avg` during datamap creation. Please add the above testcase fix it.
