I have the following table
+--------------+------------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+--------------+------------+------+-----+---------+-------+
| image_id | int(11) | YES | | NULL | |
| image_status | bit(3) | YES | | NULL | |
| image_result | varchar(4) | YES | | NULL | |
+--------------+------------+------+-----+---------+-------+
image_id and image_status columns are populated with values. The values in image_result are all NULL.
I want to insert the following values into the image_result column based on the following conditions (I want to update all the rows in the table)-
- if image_status = '0' OR image_status = '3' then image_result = 'Pass'
- if image_status = '1' OR image_status = '4' then image_result = 'Warn'
- if image_status = '2' then image_result = 'Fail'
How do I do the above?
Solution:
UPDATE table
SET image_result = CASE
WHEN image_status = 0 OR image_status = 3 THEN 'Pass'
WHEN image_status = 1 OR image_status = 4 THEN 'Warm'
ELSE 'Fail'
END
