Hi
@Buddhi Gupta,
If you are in 11.1.5 or onwards, you can click on "Show query information" in the context menu for a table you are interested in using which will allow you to see the SQL behind it. You can copy/paste this and use it as a starting point when you create a Table using SQL. There is no link between this new table created using SQL and the existing table, they are two independent tables using the same SQL query. This will allow you to reuse tables that already exist in your data module.
