how to fetch the value?

[Anonymous]

Hi All,
I m trying execute one command/function using tMongoDBRow component and
I wanna process the output returned by tMongoDBRow.
and  I m getting following output when I execute the tMongoDBRow independently.
{ "serverUsed" : "vchngskeoes2-01/10.85.17.35:27017" , "retval" : 0.0 , "ok" : 1.0}
what can be done to get the value stored in retval of above json returned, so that I can use it in the some other component.

Hi Laurent,
Thanks for the reply.
thing is I need to use count function and tmongodbinput has no option for it so only tried to use tmongodbrow.
will try to loop and get the count from tmongodbinput.
Thanks,
karthi.

I have used 'return_tMongoDBRow_1' variable which helped me to get the return value of the function.

Please help me how you returned  'return_tMongoDBRow_1' variable 
8,00,000 records. looping all the records and finding count is stupid i felt. it is taking nearly 15 mins time. 
Please post me your function urgently
