> Making use of DBDatabase.querySingleValue(cmd, conn) seems to ignore the DataType of
the select expression. This can result in erreneous behaviour, e.g. when trying to select
a number(1,0) column as boolean for Oracle, as empire-db reads the value as Number, instead
of the declared BOOL in table defintions.
