function GetDB(Name : String) : IDBConnPool;
Get a pre-existing TDBConnection. You must precreate the database using one of CreateDBODBC, CreateDBDSN, CreateDBInterbase or CreateDBMySQL. Name is the symbolic name used in whichever CreateDB variant was used when the database was originally created.
You must close the object this function returns. This will not close the connection, only dispose of the handle to the connection. If you don't dispose of the object, a memory leak will occur
