concatenating fields issue - one value not showing

Tue, 10 Jun 2014 05:15:13 GMT

I've got 2 fields: Project_ID and Seq_No

Both always have values and would never be a null

Simplified version:

LOAD

SEQ_NO

, PROJECT_ID

, SEQ_NO & '|' & PROJECT_ID AS [%My_Key]

It loads without errors, however the %My_Key values are not right

I see this:

SEQ_NO PROJECT_ID %My_Key

100024 W200 |W200 <-- I am expecting "100024|W200". All the SEQ_NO have gone missing

I've tried TEXT(SEQ_NO) & '|' & TEXT(PROJECT_ID) AS [%My_Key]

I've checked spellings, loading with just 1 field - when there is only Seq_No by itself, it works. It doesn't like the "|" nor the Project_Id being tacked on. What's its problem?

Try using text(), like:

Text(SEQ_NO) & '|' & PROJECT_ID AS [%My_Key]

Thanks Tresesco, I've tried TEXT(SEQ_NO) but it was a different issue after all - I worked out what was eating it. It's soooo obscure .

The problem was I used a "group by" and forgot to put the [%My_Key] in the "group by". It never complained that anything was wrong though... so Qlikers, beware!! If you get an issue like this, check your "GROUP BY".

Here is the code:

LOAD

SEQ_NO

, PROJECT_ID

, SEQ_NO & '|' & PROJECT_ID AS [%My_Key]

, SUM(AMOUNT)

FROM MyQVD.QVD

(qvd)

GROUP BY

SEQ_NO

, PROJECT_ID

, SEQ_NO & '|' & PROJECT_ID <---- I forgot this

This was annoying -- hopefully, QlikView will put a warning in the next SR or show a syntax error. Because in SQL, this wouldn't run.
