Description

While looking for a solution for connecting a .NET C# application to a Derby database I tried the DB2 .NET Data Provider. I thought this might work since both DB2 and Derby both use DRDA and that the DB2 JDBC driver will happily connect to Derby as well.

I had 2 different Derby instances that I used to test this and one worked just fine and the other would fail to connect with the following error:

ERROR [58004] [IBM] SQL0901N The SQL statement failed because of a non-severe system error. Subsequent SQL statements can be processed. (Reason "DRDA AR: Parser Invalid Value".) SQLSTATE=58004

Investigation showed that the failing instance was using the latest Derby version (10.8.2.2) and the working version was using an older build (10.6.1.0). Trying the release versions in order shows that the regression happens with the release builds 10.8.1.2 and later.

The DB2 .NET Data Provider can be downloaded here:

A quick sample app can be found here:

You can run it as follows:

TestDB2Connection.exe -host 192.168.229.1 -port 1547 -database IPA -user user -password foo -query "select * from APP.PERSONS"

It outputs a CSV dump of the result set
