Please help me understand converting some SQL query (see demo example below) into equivalent LookML coding;
explaining whether dimension/measures/views to achieve same data table structure in Looker/LookML.
SUM(variableA) result_LabelName, --how calculations needs to be converted in LookML?
INTO #dummyTable1 --Dummy Temporary table for values (how to work with temporary tables in LookML?)
ISNULL(after.order_date,before.order_date) order_date, --explanation: if 'after date' is null then 'before date' is stored in order_date otherwise 'after date' is stored
-- how to work with NULL/ISNULL in LookML?
CASE -- how to work with CASES equivalently in LookML?
WHEN before.order_date IS NOT NULL AND after.order_date IS NOT NULL THEN 'GREEN'
WHEN after.order_date IS NOT NULL THEN 'YELLOW'
INNER JOIN #MainTable after --how to work with joins in LookML?
ON afterDate = after.order_date
FULL OUTER JOIN #MainTable before
ON beforeDate = before.order_date
AND after.custid = before.custid
GROUP BY order_date, status
