QlikView Dynamic TableBox Creation
Reason
Sometimes it makes sense to pass some SQL Views through the whole ETL-Process to e.g. use the View “AS-IS” within a NPrinting Report. To achieve this behaviour, wenn need 2 dynamic steps:
- Extract the Views to pass through by the name based upon the schema.
- Create a TableBox for each table which has been passed through the final qvw.
Solution
Step 1
Extract the views based upon a prefix:
