adding latest free number for primary key into DB

Hi, all I suspect this is a simple one but I can't seem to figure it out.

I am using a simple flow to update a table in a SQL database, I want to add a primary key in the flow but want it to choose the latest free number, for example I think I have around 840 rows of data, how can I make it automatically pick 841 as the next primary number to upload when next run?

Hi @Genty

I think this might work for you. I'm essentially just finding the max primary key from my database, appending it onto my workflow, and then adding this number to my primary key. This gives me a dynamic method of always updating to the next number in the sequence.
