Identify Sequence of Events In BigQuery - google-bigquery

Question

I needed help with some logic for the following dataset:
ID | POST10 | EVENTS_TIMESTAMP |
1 | picked | 2022.11.06 1:00pm|
1 | profile| 2022.11.06 1:30pm|
1 | front | 2022.11.06 1:35pm|
2 | profile| 2022.11.06 1:00pm|
2 | profile| 2022.11.06 1:30pm|
2 | front | 2022.11.06 1:35pm|
2 | front | 2022.11.06 1:36pm|
3 | picked | 2022.11.06 1:00pm|
3 | front | 2022.11.06 1:30pm|
3 | profile| 2022.11.06 1:35pm|
3 | front | 2022.11.06 1:36pm|
LOGIC SHOULD BE:
FOR A PERSON, FIRST VALUE SHOULD BE "picked", THEN "profile" AND IN BETWEEN THOSE TWO VALUES, "front" did not occur.** It can occur after or before those two(based on timestamp) but not in between.
ANSWER FOR THE DATASET ABOVE WOULD BE:
ID | ANSWER |
1 | SELECTED |
2 | NOT SELECTED|
3 | NOT SELECTED|
I wrote the sql but the greater/less than(<,>) arnt working as expected. It looks at the second part after AND individually. I need it to look inside the same window between picked and profile
(case when
(min(case when (post10) like '%picked%' then EVENTS_TIMESTAMP else null end) over (partition by (ID))
>=
min(case when (post10) like '%profile%' then EVENTS_TIMESTAMP else null end) over (partition by (ID)))
AND
(min(case when (post10) like '%profile%' then EVENTS_TIMESTAMP else null end) over (partition by (ID))
>=
min(case when (post10) like '%front%' then EVENTS_TIMESTAMP else null end) over (partition by (ID)))
then 'SELECTED'
else 'NOT SELECTED' end) as ANSWER

You might consider below
SELECT ID, IF(COUNTIF(flag) > 0, 'SELECT', 'NOT SELECTED') AS ANSWER
FROM (
SELECT *, POST10 = 'picked' AND LEAD(POST10) OVER w = 'profile' AS flag
FROM sample_table
WINDOW w AS (PARTITION BY ID ORDER BY PARSE_DATETIME('%Y.%m.%d %l:%M%p', EVENT_TIMESTAMP))
)
GROUP BY ID;
