I got this Query:
$query = mysql_query("SELECT arbejdsopgave.*,
DATE_FORMAT(dato, '%d-%m-%Y') AS tid,
tilfoejelser.*,
DATE_FORMAT(datotf, '%d-%m-%Y') AS tid2
FROM arbejdsopgave LEFT JOIN tilfoejelser
ON arbejdsopgave.sub_id=tilfoejelser.sub_id2
WHERE arbejdsopgave.cat_id = '$id'
AND datotf IS NULL
OR datotf = (select max(datotf)
FROM tilfoejelser
WHERE arbejdsopgave.sub_id=tilfoejelser.sub_id2)
ORDER BY arbejdsopgave.sub_id")
or die(mysql_error());
I need to to only show rows from the table " arbejdsopgave " where arbejdsopgave.cat_id = '$id'
but also where arbejdsopgave.status = 'closed'
I tried both in the join on and in the where.
First I get everything despite the extra where. Secondly I get only the rows where there are a join.
Can anyone help me - I am amazed that i even made it this far looking at my Query... Pls help
This should work:
SELECT arbejdsopgave.*, DATE_FORMAT(dato, '%d-%m-%Y') AS tid, tilfoejelser.*, DATE_FORMAT(datotf, '%d-%m-%Y') AS tid2
FROM arbejdsopgave
LEFT JOIN tilfoejelser ON arbejdsopgave.sub_id=tilfoejelser.sub_id2
WHERE arbejdsopgave.cat_id = '$id'
AND arbejdsopgave.status = 'closed'
AND (datotf IS NULL
OR datotf = (
select max(datotf) FROM tilfoejelser
WHERE arbejdsopgave.sub_id=tilfoejelser.sub_id2) )
ORDER BY arbejdsopgave.sub_id
I suppose you forget about () around datotf OR condition
