In Slick, some examples throw this exception.
slick.SlickException: This DBMS allows only a single column to be returned from an INSERT, and that column must be an AutoInc column.
Which DBMS do support this feature?
Postgres and Oracle support returning
with multiple columns.
Mysql does not support it, but slick probably emulates it for auto increment ids with the last_insert_id()
call.
Not sure if any others support it. (They should add this to the documentation..)
