I'm trying to put up a correct string to pass as a parameter to a simple query.
Correct query that returns records:
SELECT id_s FROM group_of_id_s
WHERE date IN ('2020-08-01','2020-08-01','2020-08-02','2020-08-03','2020-08-04');
...but if I pass this (''2020-08-01','2020-08-01','2020-08-02','2020-08-03','2020-08-04'') as a parameter it doesn't work.
I also tried to pass this ('2020-08-01,2020-08-01,2020-08-02,2020-08-03,2020-08-04')
... but it also doesn't work.
My idea is to put this string as a parameter through a procedure. Perhaps like this:
IN parameter TEXT
BEGIN
SET @c = CONCAT('SELECT id_s FROM group_of_id_s
WHERE date IN (', '''' , parameter, '''', ')');
PREPARE stmt from @c;
EXECUTE stmt;
END
any reference or helpful advice would be appreciated.
EDIT: Based on very helpful example from @nbk and changing date format before comparing it to an array, I managed to put up a valid query that works like a charm. You can see it below in all of its glory. ;O) Response from @nbk is therefore considered as solution. Thanky you very much @nbk.
SELECT id_s FROM group_of_id_s
WHERE find_in_set(DATE_FORMAT(`date`, '%Y-%m-%d'), parameter) > 0;
IN.
