Test connection
Eclipse Scout needs to check if the database is available or not. There is no simple SQL statement that works on every database engine. That is the reason why this is delegated the SQL Style method testConnection(Connection conn)
For Derby:
SELECT 1 FROM SYSIBM.SYSDUMMY1
For MySql, Oracle:
SELECT 1 FROM DUAL
For Microsoft :
SELECT COUNT(1) FROM dbo.sysobjects
