How to write Filter Expression in Azure Data Flow?

问题

I have filter in Data Flow of Azure Data Factory where I need to write expression for the following SQL logic(Where statement):

Where 
ID NOT IN (Select PID from Table1 where ptype_c in (100, 2000))

回答1:

If your source is SQL Database, you can just choose Query option.

If no, you can try like this.

1.create a Filter activity, get the data which ptype_c is in (100, 2000).

2.create a Select activity, change the column name.

3.new a branch of Source.

4.create a Exist activity.
