Hell all, so let try to describe my problem in the best light possible. I have experience with Python but have never used FME. I would like to delete a full row of data based on criteria in a particular column.

Hi @herr6374​ You just need a Tester transformer - If C Is Missing then keep only the features (rows) that pass.

And if you need to delete a row in an existing dataset, you can take the output from @danatsafe​'s example and send it to a DatabaseDeleter transformer.

Can you explain to me how the operator "Attribute is Missing" is best here? If I want to detect and isolate rows with C to delete wouldn't you need something else? Or does this pass all rows that do not contain C?

Thank you sorry

If all you want to do is delete rows in a database based on the criteria of the value of an attribute, then you can use the transformer DatabaseDeleter.

Of course you'll have to adapt the criteria in the Tester to your specific case.
