Have been planning to request this for a while now.
When getting a warning saying a particular column does not exist in the query builder, it usually because when we add a new column in DB outside of Wappler, schema for the table does not update.
Another case when this happens is when switching between targets. We usually have a staging remote target & a development target. Both share the same DB.
So if I am working on development and schema is all updated, if I have to just view an existing query when on staging target, I can not even open the builder UI without having to go into Wappler DB manager, locate the table and refresh schema.
Having an option to refresh schema for the table with this warning, would be a great addition and save a lot of time.
