CREATE QUERY ageBasedSegment(String str) FOR GRAPH clientA_analytic {

      if instr(agevalue, "below") != -1 THEN
                 # Below Found
                 #begin = substr(value,0, instr(value, " "));
                 STRING lastagevalue = substr(agevalue,instr(agevalue, " ")+1, length(agevalue));
                 age_filter_customers = select s from customer:s where

      end;
      age_filter_customers = select s from age_filter_customers:s POST-ACCUM
                      INSERT INTO segment_types (PRIMARY_ID, label) 
                         VALUES ("ageBasedSegments", "Age Based Segments"),
                    INSERT INTO profile_attribute_segment (PRIMARY_ID, label) VALUES (agekey, agekey),
                    Insert into segment_profile_attribute_segment(FROM, To) VALUES("ageBasedSegments", agekey),
                    INSERT into customer_profile_attribute_segment (FROM, TO) VALUES (s.customer_id, agekey);

end;
  
   
}

here is there any other way in tigergraph to handle this:
another i need to create a lots of logic in python make it like this

https://dev.tigergraph.com/forum/t/pass-string-to-parse-it-as-jsonarray/870/3

cant we can send like this "[{“name”: “Tenagers (<18)”, “value”: “below 18”}]"

RUN QUERY test_age_based("[{\“name\”: \“Tenagers (<18)\”, \“value\”:\“below 18\”}]")
