sqlAddPK :: RawSQL () -> PrimaryKey -> RawSQL () Source #

sqlAddPKUsing :: RawSQL () -> TableIndex -> RawSQL () Source #

Convert a unique index into a primary key. Main usage is to build a unique index concurrently first (so that its creation doesn't conflict with table updates on the modified table) and then convert it into a primary key using this function.

sqlDropPK :: RawSQL () -> RawSQL () Source #
