We are going to change something that we have an enum to an id

  • 0

We are going to change something that we have an enum to an id of a linked table instead.

How would we go about that?

Our current enum name: strat
Our new linked name: stratid

What I was thinking was something along the lines of:

UPDATE table_name  
SET stratid = (SELECT id FROM link_table WHERE stratname = table_name.strat);

I have not created the link table yet, right now it is all theory.

Will the above work?
Is there anything I should change in order to transfer from an enum to the linked table?

    No gotchas for making the update other than that you need want to make triple sure that your link_table.ids are populated strictly in the order that table_name.strat options are defined.

    For example, if strat is enum('FOO', 'BAR') then in linked_table the record with id == 1 should be the “FOO” record.

    After that, you ‘d perhaps want to make the stratid column NON NULL; this is not strictly equivalent to your previous arrangement, but it would probably be closer to what you want.
