Class methods
for(connection : Connection::Base) : SchemaEditor::Base
Returns a schema editor for the passed connection.
run_for(connection : Connection::Base, atomic = true, &)
Returns a schema editor instance whose SQL operations can be enclosed in a single transaction.
By default all operations performed with the yielded schema editor object will be done inside a single
transaction, unless atomic is set to false. Note that some database backends (such as MySQL) may not
support transactions for DDL statements ; in those case the use of atomic will be ignored.
