Create View with sum

Startbeitrag von Sammy Broeders am 26.11.2014 18:56

Hello all,

I have in my project a data file as in the attach, now i want to make a view where i can see from each "Kenteken" one line with the total of "Bedrag1"
Just like this:

XT-86-TK 10824 283,25
XT-JZ-27 10823 700,76

Hi Sammy,

If this is an SL request behind the table you can simply GROUP BY Kenteken and SUM the Bedrag1 field. This will give you the desired result.

Otherwise, you will have to compute the data manually. There are many different methods to do this which are all easy. It depends of what you want to do.

- You can use a Break in the table (http://doc.windev.com/en-US/?1013305) and display to sum in it. So you still have access to the details.

- If the data is loaded manually, you can load summed data by searching if a line with the desired Kenteken exist (else add id), then add to the sum.

- You can use a simple associative array to add the values, or a standard array with structure or class to do the same: seek if exist, add/update. Then load the table or link with databinding.

Best regards,
Alexandre Leclerc

Hi Sammy,

Do you want to anchor the table as well? If so, at least in version 18 < there is an odd bug in the table when adding a break to a table. it draws the sum in the rows above where you would expect it over the normal row. There is no way to get rid of it then to remove teh anchor in the table. If no anchor the bug is gone. ( thought you would like to know )

The easyest way is to add a break to the table. No programming to do just use the 7 tabs.

1. Maybe you can try with SQL Query "SELECT Debiteurno, Kenteken FROM MyFile,...."
2. You can create view and read records (FOR EACH) , SUM on each same key and then TableAddLine() when key is changed.
