how do I do that exactly? example? ( Have no clue about SP at this point...)
Is there no easier way?

 

by: mnyePosted on 2003-07-22 at 13:19:09ID: 8980075

you can use that in a formula. just select the table in your database connection, then create a new formula and use the following script.

SELECT CASE Status
WHEN "Exclusion" THEN 2
WHEN "WATCH" THEN 1
 
place the formula in the details section with your other information and it should print out with 2s and 1s

hmmm how do I do that if tables and report are already finished?
which menupoints do I have to select (CR 8.5)

 

by: mnyePosted on 2003-07-22 at 13:42:58ID: 8980289

its fine if the report is already created. do the following:

>click "Insert" on the menu
>select "Field Object"
>right click "Formula Fields:"
>select "New"
>past in the case statement I wrote above.
>click "Save and Close" button
>expand "Formula Fields" in the "Field Explorer" (same box that poped up when you select "Field Object"
>click the formula you just created, drag onto your report and drop

ok I understand this one - but it should not print 1s and 2s etc. it should order the rows of the query in this order (first print all rows where 1 was calculated, then the ones with 2, etc...)

 

by: mnyePosted on 2003-07-22 at 14:10:40ID: 8980499

ok, then dont place in details,
>click "Report" in the top menu
>select "Sort Records"
>highlight the formula in the left pane and click the button in the middle to transfer it to the right pane
>click OK and run the report
