QV Server 10 Reload Problem

Mon, 26 Jan 2026 18:19:17 GMT

Hi all,

I've got a problem with the reload task.

My scenario is as follows:

-I have 4 qv source documents.

-Each document has a reload task that is set not to run at the same time as the other 3.

-The query behind the 4 documents all access the same database and table. In fact, it is the exact same query, just with different where clauses.

What is weird is that only 1 of the 4 tasks reload properly and that is the only one that works, regardless of whether it's by the task schedule or by manually running it.

Does anyone have any ideas of why this is occurring?

Thanks in advance.

Under Settings - Document Properties - General you may tickmark to generate logfiles and then watch what has been written there after re-run.

Have you tried the connection outside QV? Seems that it is not registered properly.

Seems to be problem with 32bit 64bit combination for QV and OLEDB driver. What version of OLEDB Provider driver you have? Is it 32 bit one?

@Rakesh: Provider=SQLNCLI.1. I've got SQLNCLI10.DLL installed.

Thanks for the replies.

@Peter: Yeah, they work. They also work with a manual reload on the same machine. It just dies on a scheduled reload.

@Rakesh: Switching the Provider from "SQLNCLI.1" to "SQLOLEDB" fixed the problem.

Thanks everyone for your help.

Sorry for the late response. In case you still have this problem, the Provider is in the connection string of the qv document.

Sorry for the late response. In case you still have this problem, we solved this problem by switching the Provider in the database connection string of the qvw document. It'll begin with "CONNECT TO [Provider=".
