Re: JDBC Driver42.2.2 throws error when dealing with money datatype

This has been discussed on the JDBC mailing list before (and belongs there) and as far as I can tell has never worked properly:

Isn't this caused by the fact that the server sends a "formatted" string including the currency symbol, decimal symbol and grouping symbols?
But Double.parseDouble(String) can't parse such a String

And I do agree with the recommendations in some of the above threads: do not use the money data type.
For all intents and purposes numeric is a much better choice.
