Knime as a low code Web App ?

Dear All,

I’m trying to create a kind of low code web app to allow manual insert and update of rows in a DB.

I can modify the rows loaded from the DB with the Table Editor view, but I din’t find how to push the changes to the DB (DB Insert, DB Update).
There’s no “validate” button …

Am I trying to build something not feasible with Knime ? Thank you

@jeremy7w welcome to the KNIME forum. I think what you are looking for is the Refresh Button.

You will have to combine this with database nodes for update and insert.

See the passage “SQL UPDATE and MERGE” for that:


Hello mlauber71,

thank you for the hints.
It was a bit hard to understand that refresh button should be placed before table view editor, but I finally understood it. Learning by doing :slight_smile:

for other users, here’s the component details
