I am doing some testing with MonetDB and the java client. I have a repeatable error that I am not sure if it is a but or the way I am using the tool. I have an Oracle background so it could be me. Java client connection on Windows 2000 Professional to MonetDB on openSuSe 10.1 using SQL. Thanks for your help.
