DatabaseReader unable to handle SQL AS?

Hi,

I just tried an SQL Statement in a DatabaseReader node similar to

SELECT t1.column AS name1, t2.column AS name2 FROM table t1, table t2

I would have expected KNIME to use the names "name1" and "name2" in its output table, but instead I get "column" and "column (#1)" and a warning stating:

"CODING PROBLEM    DataSpec generated by configure does not match spec after execution.
ERROR     Database Reader     DataSpec generated by configure does not match spec after execution."

Is this a known bug? Is there a workaround or am I doing something wrong?

Regards

Does this help to solve the problem?
