Hey all,

I’m trying to build a feature in my app where I allow users to create custom columns in my tables via API.

I have this working by itself, but I wanted to make the type of the column a variable that can be dynamically inserted. For some reason, I can’t get this to work with all the methods I’ve tried. Not sure if this is a limitation or something I’m doing wrong.

Any help is appreciated!

Eh, figured it out. Use the concat function with a break 🤙

You most probably shouldn’t be doing this in a public app (non internal)

Haha yes, this is only internal for our team. Each user has a unique token for logging/audit, too.
