DB Copy Plugin is a database copying plugin for the SQuirreL SQL Client. It makes it possible to copy and paste tables from one session to another and between different databases and includes primary key and foreign key constraints for copied tables, and uses Hibernate 3.0 internally to perform database object type mappings. It supports Firebird, Oracle, Sybase, MS SQL Server, MySQL, HyperSonic, Pointbase, and PostgreSQL, and allows the user to select a Hibernate dialect for the destination database if one couldn't be determined automatically.
