BIRT: Sorting Data Sets

0
Andrew Trobec (497●13●144●139) | asked Sep 07 '10, 4:11 a.m.
Good Morning,

I am trying to create a BIRT data set that is sorted (1) by WI_ID and (2) by TIME_ID.TIMESTAMP so as to have a list of all work items ordered by ID and timestamp, with a computed column ranking them. For example i would like to have the following result:

FACT_ID 2 | WI_1 | 1 Sep 2010 16:03 | RANK 1
FACT_ID 5 | WI_1 | 1 Sep 2010 16:30 | RANK 2
FACT_ID 3 | WI_2 | 1 Sep 2010 16:05 | RANK 3
FACT_ID 6 | WI_2 | 1 Sep 2010 16:40 | RANK 4
FACT_ID 1 | WI_3 | 1 Sep 2010 15:17 | RANK 5
FACT_ID 4 | WI_3 | 1 Sep 2010 16:25 | RANK 6

Since I cannot do this without reading the data into some sort of variable, please can I have some information on how to do this? Also, how do I then take replace the data set with the sorted information, making sure that the rank column is added? I have found many tutorials, but I cannot make enough sense of them to be able to do what I want.

Thank you in advance.

Best regards,

Andrew

Edit

I tried adding the following code to the beforeOpen script of my data set:

queryString = this.queryText;
queryString = queryString + " ORDER BY WI_ID ASC";
this.queryText = queryString;

Unfortunately it does not work. Is there anything else I can do?

Sorting is accomplished by using the sort tab of the Properties Editor of the table.

Hello Kirk,

Thank you for your reply.

I am aware of the possibility of sorting within the layout, but the data sets that I am trying to sort represent the first step of the final data set (which will be a join between the two) that I want to use in the layout.

What I want to do is create two data sets that are in the above mentioned form (with rank), then create a third data set which would join the first two using the rank as key that I can then use in the report layout. In order for it to work, though, I need to be able to sort the first two data sets using some sort of script.

Regards,

Andrew
