Data source size from QVD size

[#1]

Hi ,

is that possible to deduce the Data Source size  from QVD size?

According to this artcle Qlikview Notes: Document Compression, Data Source=10* QVD Size

[Gysbert_Wassenaar]

No, not really. Suppose your source data is xml files. Then compression rate could be in the thousands.

So you don't have an exact ratio??

Is there a way to display the size of selected data? when loading the scipt we can see only rows' number.. Any idea??

[Jason_Michaelides]

You can get the number of rows or fields in a QVD file using:

QVDNoOfRecords('Filename')

and

QVDNoOfFields('Filename')

Might help in an estimation of data size. One times the other would give total cells, for example. Doesn't help with cardinality etc though.

Hope this helps,

Jason
