Crystal report; Combining rows of data into a single value

Crystal report; Combining rows of data into a single value or

Concatenate Column Values from Multiple Rows into a Single Column

I have two field like this

field1  field2
1         a@xyz.com
2        b@xyz.com
3         c@xyz.com
4         d@xyz.com


I wanted output like:
a@xyz.com , b@xyz.com, c@xyz.com, d@xyz.com


Solution

In Report header put a formula @initializeVar which will work as global variable:


WhilePrintingRecords;
StringVar Conc_emailID := "";

In Group Header or Detail Section (Wherever u want) put a formula @updateVar to concatenate the cell value of each row:


WhilePrintingRecords;
StringVar Conc_emailID := Conc_emailID + {tablename.field2}+ ',' ;

In Report Footer finally access the concatenated value from variable by putting a formula field @showVar :


WhilePrintingRecords;
StringVar Conc_emailID;


It will give you the desired output.
