Error with Varchar fields

Hi everybody,
I’m not able to read MySql database tables if they contain VARCHAR fields. Converting them from varchar to char (or int) it works… I’m using KNIME SDK 2.0.1

The error is:
“ERROR Database Connection Reader Execute failed: Operation not yet supported”

The error is generated when the Database Connection Reader node tries to read the table.


I am using MySQL 5.0.41 and KNIME 2.0.1 and I am reading a database table with ~20 VARCHAR columns, ranging from VARCHAR(3) to VARCHAR(200) without any problems. Could you describe in more detail what you are doing (MySQL version, data table description)?
