INTERVAL_NUMBER Function

The INTERVAL_NUMBER function can be referenced only in the SELECT expression.

Query

SELECT t1.entity, t1.metric, t1.datetime,
  t1.value, t5.text AS "Unit Batch Id", t6.text AS "Unit Procedure",
CASE INTERVAL_NUMBER()
  WHEN 1 THEN t5.text
  ELSE CONCAT(t5.text, '.', INTERVAL_NUMBER())
END AS "Unit Batch Number"
  FROM atsd_series t1
    JOIN "TV6.Unit_BatchID" t5
    JOIN "TV6.Unit_Procedure" t6
WHERE t1.metric = 'tv6.pack:r01'
  AND t1.datetime BETWEEN (SELECT datetime FROM "TV6.Unit_BatchID" WHERE entity = 'br-1211' AND (text = '800' OR LAG(text)='800'))
  AND t1.entity = 'br-1211'
WITH INTERPOLATE(60 SECOND, AUTO, OUTER, TRUE, START_TIME)
  ORDER BY t1.datetime
