Problem with example application and temporary workaround

vadimtsushko — Tue, 22 Jul 2025 17:59:49 GMT

I'm currently looking at sample applications in QDF. One of them - NorthWindExampleMart.qvw - breaks on load with error

Ошибка в строке скрипта:

for vL.tttt = 0 to vL.xxxx-1

Oшибка в строке скрипта: stands for something like Error in script line:

Firstly I've checked that I generated QVDS by QVD-Generator-Example.qvw and loaded successfully Example_NorthWind_Mart.qvw datamart. Then I tried to debug this error, unsuccessfully.

Finally I've noticed some irregularity in NorthWind_Mart.qvw on table view:

All tables have names corresponding to they source QVD file names, but instead of Customer table we have vL.temp_table.

I've added

RENAME TABLE vL.temp_table TO Customer

at the end of Example_NorthWind_Mart.gvw script and after that NorthWindExampleMart.qvw application loads successfully for me.

If somebody stumbled upon same error, that may be quick workaround.

Best regards, Vadim Tsushko

Hi Vadim, In the new QDF 1.3.2 version there is a new function called QVDLoad.
This function will load in muliple qvd files (in multiple folders) and create data-model based on qvd header meta-data.

In the Northwind Mart case you only need these lines instead of Load *

$(Include=$(vG.SubPath)\10.QVDLoad.qvs);

call QVDLoad('$(vG.QVDPath)');

Read more in the updated development guide.

Best regards

Magnus

Great solution, Magnus.

I will definitely use it.

Replying to an old thread, but hopefully someone dealing with the same issue finds the solution.

The problem for us was that the tables are not given a name during the load. This creates the vL.temp_table in some point of the reload while QDF is active. So a solution for us was to give the table name in a variable for each table in loop.
