SAS Intelligent Decisioning: How to dynamically increment numeric datagrid variable

KidCat — Wed, 06 Oct 2021 10:21:40 GMT

Hi,

I wrote some DS2 package code, working fine except for one tiny thing.

The "method execute" part creates a datagrid variable MYRESULT.

Depending on some if-then-elses, I would like to populate this datagrid variable.

dcl double Row_Num ;

datagrid_addcharactercolumn(MYRESULT, '1st_Col');

datagrid_addcharactercolumn(MYRESULT, '2nd_Col');

datagrid_addcharactercolumn(MYRESULT, '3rd_Col');

datagrid_addnumericcolumn(MYRESULT, 'Row_Num');

(...)

if doh-doh-doh then do;

Row_num=datagrid_addrow("MYRESULT");

datagrid_set('MYRESULT', '1st_Col', Row_Num, 'MyEntry1'));

datagrid_set('MYRESULT', '2nd_Col', Row_Num, 'MyEntry2');

datagrid_set('MYRESULT', '3rd_Col', Row_Num, 'MyEntry3');

end;

(...)

;

if dah-dah-dah then do;

Row_num=datagrid_addrow("MYRESULT");

datagrid_set('MYRESULT', '1st_Col', Row_Num, 'MyEntry1'));

datagrid_set('MYRESULT', '2nd_Col', Row_Num, 'MyEntry2');

datagrid_set('MYRESULT', '3rd_Col', Row_Num, 'MyEntry3');

end;

DS2 creates MYRESULT and four columns.

Assuming these two conditions apply, I'd expect Row_Num to be populated with 1 and 2.

However, it's empty. Any idea why?

Any pointer appreciated!

Return data type for DATAGRID_ADDROW function is integer. You have declared Row_Num variable as a double. Please change data type and try again.

Adjusting to integer didn't solve the issue.

Try to print it before inserting to the data grid. Do you see anything there?

In this case, the grid variable is the only result.

My original question tends to change to how to properly implement a _N_ equivalent using DS2...
