Add calculated field in existing view using derived table


(Vishal) #1

Hi ,
I’m trying to create a new flag within existing view in lookML using calculated field built by SQL query .
This new field should be added as a dimension within existing view . It looks like I’m running into syntax issues… can any one help.

Here is syntax:
view: New_Traveler_Flag {
derived_table: {
select snapshotdate,travelerfirstentrysourcedate , cast(snapshotdate as date) - interval ‘7’ day New_Trav_Date
where travelerfirstentrysourcedate != ‘9999-12-31’
and snapshotdate >= cast(snapshotdate as date) - interval ‘60’ day;;
dimension: new_traveler {
type: number
sql: CASE WHEN cast(${TABLE}.travelerfirstentrysourcedate as date) >= ${TABLE}.New_Trav_Date THEN 1 ELSE 0 END;;
measure: count {
type: count
