Hi Pavel, Thank you for your reply. I tried the query and it is returning result as , for a single entry in sample info in separate rows
The result of the query as 1, prop1,value1 1,prop2,value2 2,prop1,value1 2 prop2,value2 2 prop3,value3 but i want the output as single row per sample id like 1,value1,value2 2 value1,value2,value3 Is this possible? or functions will help to get the result? please help.
