How do I build a general query based in a list of tables and run/export the results?
Here is my conceptual structure
Basically the from clause in query would be inserted by the table rows. After that, each schema.table with true result returned must be stored in a text archive.
Could someone help me?
As pentaho doesn't support loops, it's a bit complicated. Basically you read a list of tables and copy the rows to the result and then you have a foreach-job that runs for every row in the result.
I use this setup for all jobs like this: How to process a Kettle transformation once per filename
In the linked example, it is used to process files, but it can be easily adapted to your use.
