The Little Guy Posted May 2, 2010 Share Posted May 2, 2010 I have a table that has a column that has the week day (Sunday - Saturday). I have a query, and I ALWAYS want it to return 7 rows (Sunday - Saturday). SELECT COUNT(*) as total, weekDay FROM sts_cal WHERE pid = '1' GROUP BY weekDay if the column total doesn't have anything I want it to say 0, otherwise put the total... Does this make sense?

Zane Posted May 2, 2010 Share Posted May 2, 2010 LIMIT 7 Link to comment https://forums.phpfreaks.com/topic/200490-return-7-rows-always/#findComment-1052086 Share on other sites More sharing options...
The Little Guy Posted May 2, 2010 Author Share Posted May 2, 2010 LIMIT 7 wont work. Currently my table has 4 values in it, all are "Sunday" (today). I want to return "Monday", "Tuesday", etc. but those days are not in there. Right now it returns this: total weekDay 4 Sunday I would like it to return this: total weekDay 4 Sunday 0 Monday 0 Tuesday 0 Wednesday 0 Thursday 0 Friday 0 Saturday does that make better sense? total will change weekDay will not, but there will ALWAYS be those seven thing returned. Possible? Link to comment https://forums.phpfreaks.com/topic/200490-return-7-rows-always/#findComment-1052093 Share on other sites More sharing options...

The Little Guy Posted May 4, 2010 Author Share Posted May 4, 2010 So... Is this possible? Link to comment https://forums.phpfreaks.com/topic/200490-return-7-rows-always/#findComment-1052842 Share on other sites More sharing options...
trq Posted May 4, 2010 Share Posted May 4, 2010 if the column total doesn't have anything I want it to say 0, otherwise put the total... So write that logic into your loop while your outputting the results. Nothing to do with mysql.

fenway Posted May 4, 2010 Share Posted May 4, 2010 You're trying to select something that's not there? You just need to join in a derived table that contains one row for each required date. Either use an integers table to generate it, or just UNION 7 records.

The Little Guy Posted May 4, 2010 Author Share Posted May 4, 2010 Thanks Fenway! SELECT COUNT(*) as total, 'Sunday' as lbl FROM sts_cal WHERE pid = '{$this->pid}' AND weekDay = 'Sunday' UNION SELECT COUNT(*) as total, 'Monday' as lbl FROM sts_cal WHERE pid = '{$this->pid}' AND weekDay = 'Monday' UNION SELECT COUNT(*) as total, 'Tuesday' as lbl FROM sts_cal WHERE pid = '{$this->pid}' AND weekDay = 'Tuesday' UNION SELECT COUNT(*) as total, 'Wednesday' as lbl FROM sts_cal WHERE pid = '{$this->pid}' AND weekDay = 'Wednesday' UNION SELECT COUNT(*) as total, 'Thursday' as lbl FROM sts_cal WHERE pid = '{$this->pid}' AND weekDay = 'Thursday' UNION SELECT COUNT(*) as total, 'Friday' as lbl FROM sts_cal WHERE pid = '{$this->pid}' AND weekDay = 'Friday' UNION SELECT COUNT(*) as total, 'Saturday' as lbl FROM sts_cal WHERE pid = '{$this->pid}' AND weekDay = 'Saturday' Link to comment https://forums.phpfreaks.com/topic/200490-return-7-rows-always/#findComment-1053107 Share on other sites More sharing options...

The Little Guy Posted May 4, 2010 Author Share Posted May 4, 2010 What did you mean? Is there a better more efficient way to do this? Link to comment https://forums.phpfreaks.com/topic/200490-return-7-rows-always/#findComment-1053251 Share on other sites More sharing options...
fenway Posted May 4, 2010 Share Posted May 4, 2010 Probably not in this case, assuming proper indexes. Link to comment https://forums.phpfreaks.com/topic/200490-return-7-rows-always/#findComment-1053293 Share on other sites More sharing options...
