Data
I am trying to select right template name based on date. "Valid" column represents date till template is valid. If Template have 0000-00-00 or NULL valid date, that means that this template is current (latest). Template names does not suggest order (they can be random string).
Scenario:
If I have user, that will be created let's say 2020-01-01, then select should pick template with name "yes_4".
Scenario:
User was created in 2018-01-01, then template selected should have name "agreement_x"
Scenario:
User created in 2019-01-15 will select row with name "template_2"
So far:
:date = - user created
query
SELECT * FROM `template`
WHERE DATE(`valid`) < DATE(:date)
ORDER BY DATE(`valid`) DESC
LIMIT 1

Something like
( SELECT *
FROM `template`
WHERE DATE(`valid`) >= DATE(:date)
ORDER BY DATE(`valid`)
LIMIT 1
)
UNION ALL
( SELECT *
FROM `template`
WHERE DATE(`valid`) <= '1970-01-01' OR `valid` IS NULL
)
ORDER BY `valid` DESC
LIMIT 1
or
SELECT *
FROM `template`
WHERE CASE WHEN DATE(`valid`) > '1970-01-01'
THEN `valid`
ELSE '2038-01-19'
END >= DATE(:date)
ORDER BY CASE WHEN DATE(`valid`) > '1970-01-01'
THEN `valid`
ELSE '2038-01-19'
END
LIMIT 1
and so on...
