I have 20 QVD's.... I need whole data from 20 QVD's.
Using Concatenate i made one QVD, but it's talking more reloading time.
(Note: Few tables i have same fields)
Concatenate is make sense??
How to improve performance...???
Please give me suggestions...
Thanks in Advance....
If you take 20 qvds data into single Qvd there are questions to be ask.
1. Will all qvd has same fields.
2. Try the incremental load onto the qvd loading and then concatenate to increase the performance.
3. Try to create to optimized qvd that will take less time to load means take only necessary data.
If all your 20 QVDs having the same structure i.e same number of fields with same name then you can probably use '*' to load all QVDs like below
But if all the QVDs don't have same structure then You should go for concatenate, but question here is
What is the reason for creating Separate 20 QVDs?
Hi QV Tester,
My Suggestion is first choose Big Qvd's which are having huge amount of data fetch these all are into one QVW file and now
Create ur new qvw file with binary load for huge amount of data files and fetch remaining qvd's also depends on logic
Note:- Comparatively QVD's load ,Binary Load is a bit fast.
I have 20 views fetching form SQL.
I need whole data. because of that i have concatenate all QVD's.
7 tables are almost same structure, remaining QVD's only 2, 3 fields same.
