Best way to access SQL database from QVW file

[#1]

Hi!

I have a big database on SQL and need the qvw files to access it. I want to know which would be the most efficient way to get the data.

Should I access directly to the SQL database, create a QVD that updates from time to time or use a QVX file?

And how to use it?

Thanks!

If you have a big data in a SQL database, for me, the best solution is create a qvd file with the data more stable (no changing in the time)

See this:

SQLServer to QVD

it depends on BIG

usually and if possible, for big table in Qlik you can use incremental load and QVD

in Qlik online help you can find the different type of incremental load
