Currently getting the error "Window framing expression must be a literal or parameter at [x:x]", it works fine using just the number 5 but this is used a lot throughout my script.
DECLARE variable INT64;
SET variable = 5;
SELECT col1, value, time,
CASE
WHEN "Bla" = "Bla"
THEN MIN(value) OVER (PARTITION BY col1 ORDER BY time ROWS BETWEEN variable PRECEDING AND CURRENT ROW)
ELSE NULL
END
AS MinVal
FROM data
You can use execute immediate to execute dynamic queries. For eg. Below query uses var in over clause.
declare var int64 default 5;
execute immediate
'select min(1) over(order by street_number ROWS BETWEEN '||var||' PRECEDING AND CURRENT ROW) from' ||'`bigquery-public-data.austin_311.311_service_requests` limit 100'
