I have column (submit_type) inserting new column in that value are set by CASE condition here is my sql query:
SELECT s.shot_id,
s.shot_name ,
isn.reviewer AS 'submitted_by_supervisor',
isn.version AS 'version_submitted',
isn.grade AS 'grade',
CASE
WHEN isn.version = Min(isn.version) THEN 'FRESH'
ELSE 'Once Submitted'
end AS 'submit_type'
FROM viewd_elx.india_supe_note isn
JOIN viewd_elx.shot s
ON s.shot_id = isn.shot_id
JOIN viewd_elx.team t
ON isn.shot_id = t.shot_id
JOIN viewd_elx.viewd_team vt
ON isn.shot_id = vt.shot_id
WHERE isn.promoted='Yes'
AND isn.grade IN ('A',
'B')
GROUP BY isn.grade,
s.shot_id,
isn.version;
mentioned query gives 'Fresh' value in all field in (submit_type) column. which is not correct.
What I need exactly is, I am grouping column and finding MIN(value) of column,
Work Flow: - grade A => group (shot_name) => min(version_submited) => set 'Fresh' else 'Once submitted' in (submit_type)
In Grade 'A' have same shot_name, grouping this (shot_name) and then finding min(version_submited) if min value found then set 'fresh' else set 'once submitted' value in (submit_type) column. Also for Grade B like Grade A.
I need result like this =>
+----+-------+-----------------------------+-------------------------+-------------------+----------------+
| Id | grade | shot_name | submitted_by_supervisor | version_submitted | submit_type |
+----+-------+-----------------------------+-------------------------+-------------------+----------------+
| 27 | A | elx_reel01_scn1020_shot1720 | Salil Devji | 33 | Fresh |
| 27 | A | elx_reel01_scn1020_shot1720 | Deepali | 34 | Once Submitted |
| 37 | A | elx_reel01_scn1030_shot3480 | Salil Devji | 15 | Fresh |
| 37 | A | elx_reel01_scn1030_shot3480 | Salil Devji | 20 | Once Submitted |
| 7 | B | elx_reel01_scn1010_shot1030 | Darshan | 4 | Fresh |
| 7 | B | elx_reel01_scn1010_shot1030 | Varion | 6 | Once Submitted |
| 17 | B | elx_reel01_scn1010_shot1140 | Varion | 17 | Once Submitted |
| 17 | B | elx_reel01_scn1010_shot1140 | Varion | 14 | Fresh |

The issue here is that you are grouping by on isn.version
field as well, and trying to compute the minimum of the same field in that group. It will simply return the same value, and that is why all are coming as "Fresh". You will need to determine the minimum isn.version
value for a group of (grade, shot_id)
separately in a subquery ( Derived Table ), and then use that to check whether minimum or not.
SELECT s.shot_id,
s.shot_name ,
isn.reviewer AS submitted_by_supervisor,
isn.version AS version_submitted,
isn.grade AS grade,
CASE
WHEN isn.version = dt.min_version THEN 'FRESH'
ELSE 'Once Submitted'
END AS 'submit_type'
FROM viewd_elx.india_supe_note isn
JOIN viewd_elx.shot s
ON s.shot_id = isn.shot_id
JOIN viewd_elx.team t
ON isn.shot_id = t.shot_id
JOIN viewd_elx.viewd_team vt
ON isn.shot_id = vt.shot_id
JOIN (
SELECT grade,
shot_id,
MIN(version) AS min_version
FROM viewd_elx.india_supe_note
WHERE promoted = 'YES'
AND grade IN ('A', 'B')
GROUP BY grade,
shot_id
) AS dt
ON dt.grade = isn.grade
AND dt.shot_id = isn.shot_id
WHERE isn.promoted='Yes'
AND isn.grade IN ('A','B')
GROUP BY s.shot_id,
s.shot_name,
isn.reviewer,
isn.version,
isn.grade,
dt.min_version
