If you have stored procedures, you can copy them afterwards:ĬONSTRAINT ĬONSTRAINT D_SomeTable_SomeCol -When Omitted a Default-Constraint Name is autogenerated.ĭEFAULT (0)-Optional Default-Constraint. If that is the case, use a traditional way to clone a database and then drop the old one: If some table has a trigger, it cannot be moved to another database using above method (will result Trigger in wrong schema error). ![]() If your database has no password, remove the -u username -ppassword part.
