[SOLVED] Filtering HDIFF results

I have a compute of HGETC ( 10 , 'HYYMDm' ) with a format of HMDYY.S and I have a second compute of HDIFF ( Compute_1 , DT_TM_END , 'HOURS' , 'D12.0' ) . I have tried using LE a numeric value in the second compute but it will not bring back the results, it brings back all results. I am trying to limit the search to say 60 hours between the two dates. I want the ability to bring data within a certain amount of hours between NOW and a table that has transactions going back 90 days.

Hi Jason68

First of all welcome to Focal Point. I see you have been a member for quite a while but this is your first post...

WebFOCUS gets all the results of the request and then does the computes. Although I have never tried to filter on the results of two computes I don't think it will work. Hopefully someone else will have some insight to this.


Thank you for using Focal Point!

In order to debug your code, you should remove the WHERE test and see what the computed value is. Does the calculation look right?

Also, try a DEFINE instead of a COMPUTE. DEFINE will generate a value for each database row.

It would be terrific if you could create a very simple example and post the code here so we understand what you're doing.

As Babak suggested, once you are sure that your COMPUTEs return the proper value, you can create a third one to perform the difference between the first two then use
WHERE TOTAL ThirdCompute LE xx;


Such as this sample :
TABLE FILE CAR
SUM RETAIL_COST
    DEALER_COST
    COMPUTE NRET /P6C = RETAIL_COST / 10;
    COMPUTE NDEL /P6C = DEALER_COST / 2;
    COMPUTE DIF  /P6C = NDEL - NRET;
BY CAR
BY MODEL
WHERE TOTAL DIF GT 3000;
END
-RUN
