Makes all changes made since the previous commit/rollback permanent and releases any database locks currently held by this Connection object. This method should be used only when auto-commit mode has been disabled. @exception java.sql.SQLException if a database access error occurs,this method is called while participating in a distributed transaction, if this method is called on a closed conection or this Connection object is in auto-commit mode @see #setAutoCommit
