Help with grouping issue please

[gvp16]

Hi all, I need some help with the following query please, which I am using to consolidate a set of results into a single row via joins, I have done similar queries like this in the past with no problem, but with this query when I am grouping by username or userid the columns are being shown as null

SELECT t.user_id, 
u.username as name, 
tm.content as monday, 
tt.content as tuesday, 
tw.content as wednesday, 
tth.content as thursday, 
tf.content as friday, 
ts.content as saturday, 
tsu.content as sunday 
FROM timesheets t 
LEFT JOIN users u on u.id = t.user_id L
EFT JOIN timesheets tm on t.id = tm.id AND WEEKDAY(tm.`date`) = 1 
LEFT JOIN timesheets tt on t.id = tt.id AND WEEKDAY(tt.`date`) = 2 
LEFT JOIN timesheets tw on t.id = tw.id AND WEEKDAY(tw.`date`) = 3 
LEFT JOIN timesheets tth on t.id = tth.id AND WEEKDAY(tth.`date`) = 4 
LEFT JOIN timesheets tf on t.id = tf.id AND WEEKDAY(tf.`date`) = 5 
LEFT JOIN timesheets ts on t.id = ts.id AND WEEKDAY(ts.`date`) = 6 
LEFT JOIN timesheets tsu on t.id = tsu.id AND WEEKDAY(tsu.`date`) = 7
GROUP BY t.user_id

See screen shot for example before and after the grouping.

 

Help would be greatly appreciated.

 

Thanks.

What do you expect to get by grouping these things together? How does one group NULL and "test"? How would you group "one" and "two"?

 

What you're asking in the query doesn't quite make sense - that's why you're not getting the results you want.

 

[edit] I'll jump to the chase. Have you considered GROUP_CONCAT()?

I was hoping to return one row per user with the each day populated.

 

Thanks, I will try Group_concat and report back.

Right, but with the screenshot you posted there are multiple rows for the same user+day somewhere. If that wasn't the case then there would be only the one row, as you are expecting to get.
