Hi!
I need your help because I have to formatting values in decimal into one column of one table (I connected to POstgreSQL).
This column shows now values with , as separator. I do not want , as separator.
I think I need format this column.
How can I do that?

The column is this:

And I need to eliminate , in this field.

Many thanks

If these are whole numbers, you can convert using Double to Int node and “,” will get eliminated.
Does this help?

This node does not work because I have a db table selector before…I connected to a db through Athena Connector:
