Load data if

Arianna1 — Mon, 20 Dec 2021 21:38:40 GMT

I'd been looking through Community about that but I couldn't find solution to my problem
From the logic:
if condition then
statement;
else statement;
end if

i would like to use as condition the load of at least one record from qvd file.
Any suggestions?

Thanks

if you want only load first record you can use :

TMP: First 1 LOAD Value FROM ...

if you want test if else ...

suppose i have a qvd file with one field Value=1,2,3,4

i wan use if else to test the first record if its 1 or no

i can use if in load like this :

TMP: First 1 LOAD Value FROM YOURQVD.qvd (qvd); let firstvalue=peek('Value'); if '$(firstvalue)'=1 then let trace=1; elseif '$(firstvalue)'<>1 let trace=0; end if

if i show the trace variable :
