Hi Community
I'm hoping someone can help me, my QlikView skills are non-existant. I am tring to load specific records from a table into Qlikview - using the Table below as an example, I want to load only the green highlighted records:
Table:
ID | Sequence | Value |
1 | 1 | whatever |
1 | 2 | whatever |
1 | 3 | whatever |
2 | 1 | whatever |
2 | 2 | whatever |
3 | 1 | whatever |
3 | 2 | whatever |
3 | 3 | whatever |
3 | 4 | whatever |
Essentially I need to pull in the Value for each ID in the table with the highest Sequence nunber. Does anyone have any suggestions please.
Cheers!
If you're loading from an sql database you can create an sql statement that returns only the records you want. If you have to load from a file then you have to load all records first and then get rid of those you don't need. That would look something like this:
T1:
Load ID, Sequence, Value
from ...somefile...;
right join load ID, max(Sequence) as Sequence
resident T1 group by ID;

TEMP:
LOAD * INLINE [
ID,Sequence,Value
1, 1, 3
1, 2, 110
1, 3, 0
2, 1, 120
2, 2, 1
3, 1, 50
3, 2, 60
3, 3, 70
3, 4, 200
3, 5, 400
];
Final:
Load ID as ID,
max(Sequence) as Sequence
Resident TEMP
group by ID;
Inner Join
Load * resident TEMP;
Drop table TEMP;
This should solve your problem. Please check and let me know
Hi Gysbert
Thanks for your really quick reply. I am loading from an SQL dB, I should have said.
I don't pretend to know how that has worked, but it has - thanks a lot.
Cheers!
Hi Anand
Thanks for replying - I don't doubt your solution would have worked but I tried the first response and that has worked for me.
Cheers!
