"DB Example Source"

dendi_rm

Dear Master,

I use oracle database example source.
But got error message like this:

"Process failed
Runtime Exception caught
Cannot update data: java.sql.SQLException: Invalid operation for read only resultset: updateDouble"

Please help.
What should I do ?

Thank You.

Hi Dendi,

In your last post you mentioned the 'work on database' option, so I suspect that you are not on the latest version of RapidMiner ( 5.1 ) you should upgrade as the database access is easier, with tools for managing connections. Your errors could anyway come from sources that have nothing to with RM - http://www.coderanch.com/t/301466/JDBC/java/Invalid-operation-read-only-resultset - Google is full of them  .

PS. No need to post twice.
