Filtering/Comparing Null/Blank String Fields

[#1]

Greetings gentlemen and ma'ams!!!

I am trying to bring only fields that are not blank or null during a LOAD / LEFT JOIN statement, but unsuccesfully.

The code follows below:

LOAD

Customer_Shipper

,

SUM

(Teus) AS

SUMTEUS

FROM

[..\..\Qvd\CSAV_BRASIL\MercadoECSA.qvd](qvd)

;

LEFT

JOIN

LOAD

Shipper

AS Costumer_Shipper

,

[Partner Code]

FROM

[..\..\Datos Externos\CSAV_BRASIL\dicionario mercado-csav\dicionario.xls] (biff, embedded labels, table is Sheet1$

)

WHERE

NOT EXISTS(Costumer_Shipper,''

)

GROUP

BY Customer_Shipper,

[Partner Code];

and the following errors are dysplayed after running the script:

... as far as I can see, my code doesn't seem to be out of logic, and I just can't figure out what's wrong...

Could someone shed some light upon this, PLEASE???

In advance, my apologies if this is an seely question (official noob here).

Thx!!!

Hi,

you are using a SUM function and an additinal field CUSTOMER_SHIPPER or so.

That´s the reason you need a GROUP BY statement so that SUM can work correctly.

Load

Customer_Shipper

Sum(TEUS) as SumTeus

From *****

Group By Customer_Shipper;

But you are loading your data from a QVD file. Not sure at the moment if it works in this case.

Maybe you have to load the table again by a resident statement.

Good luck!
