Answer 1

I finally got the answer.

I am using Workbench for the SQL client, and it default show 2 decimal place only. I have to change it inside the options setting.

Answer 2

To change the default of just two decimal digits, change the SQLWorkbench's data formatting. This can be achieved by

Preferences -> Data Formatting -> Decimal digits -> to 3 (based on the above example).
