I currently have a DataStudio dashboard connected to a BigQuery custom query.
That BQ query has a hardcoded date range and the status of one of the columns (New_or_Relicensed
) can change dynamically for a row, based on the dates specified in the range. I would like to be able to alter that range from DataStudio.
I have tried:
simply connecting the DS dashboard to the custom query in BQ and then introducing a date range filter, but as you can imagine - that does not work because it's operating on an already hard-coded date range.
reviewing similar answers, but their problem doesn't appear to be quite the same E.g. BigQuery Data Studio Custom Query
Here is the query I have in BQ:
SELECT t0.New_Or_Relicensed, t0.Title_Category FROM (WITH
report_range AS
(
SELECT
TIMESTAMP '2019-06-24 00:00:00' AS start_date,
TIMESTAMP '2019-06-30 00:00:00' AS end_date
)
SELECT
schedules.schedule_entry_id AS Schedule_Entry_ID,
schedules.schedule_entry_starts_at AS Put_Up,
schedules.schedule_entry_ends_at AS Take_Down,
schedule_entries_metadata.contract AS Schedule_Entry_Contract,
schedules.platform_id AS Platform_ID,
platforms.platform_name AS Platform_Name,
titles_metadata.title_id AS Title_ID,
titles_metadata.name AS Title_Name,
titles_metadata.category AS Title_Category,
IF (other_schedules.schedule_entry_id IS NULL, "new", "relicensed") AS New_Or_Relicensed
FROM
report_range, client.schedule_entries AS schedules
JOIN client.schedule_entries_metadata
ON schedule_entries_metadata.schedule_entry_id = schedules.schedule_entry_id
JOIN
client.platforms
ON schedules.platform_id = platforms.platform_id
JOIN
client.titles_metadata
ON schedules.title_id = titles_metadata.title_id
LEFT OUTER JOIN
client.schedule_entries AS other_schedules
ON schedules.platform_id = other_schedules.platform_id
AND other_schedules.schedule_entry_ends_at < report_range.start_date
AND schedules.title_id = other_schedules.title_id
WHERE
((schedules.schedule_entry_starts_at >= report_range.start_date AND
schedules.schedule_entry_starts_at <= report_range.end_date) OR
(schedules.schedule_entry_ends_at >= report_range.start_date AND
schedules.schedule_entry_ends_at <= report_range.end_date))
) AS t0 LIMIT 100;
Essentially - I would like to be able to set the start_date
and end_date
from google data studio, and have those dates incorporated into the report_range
that then influences the operations in the rest of the query (that assign a schedule entry as new
or relicensed
).

I had a similar issue where I wanted to incorporate a 30 day look back before the start (@ds_start_date). In this case I was using Google Analytics UA session data and using table suffix in my where clause. I was able to calculate a date RELATIVE to the built in data studio "string" dates by using the following: ...
WHERE
_table_suffix BETWEEN
CAST(FORMAT_DATE('%Y%m%d', DATE_SUB (PARSE_DATE('%Y%m%d',@DS_START_DATE), INTERVAL 30 DAY)) AS STRING)
AND
CAST(FORMAT_DATE('%Y%m%d', DATE_SUB (PARSE_DATE('%Y%m%d',@DS_END_DATE), INTERVAL 0 DAY)) AS STRING)

Have you looked at using the Custom Query interface of the BigQuery connector in Data Studio to define start_date and end_date as parameters as part of a filter.
Your query would need a little re-work... The following example custom query uses the @DS_START_DATE and @DS_END_DATE parameters as part of a filter on the creation date column of a table. The records produced by the query will be limited to the date range selected by the report user, reducing the number of records returned and resulting in a faster query:
