I tried it. Doesn't works.
Without group by i have this set:
id name c
1 user1 '50'
2 user1 'twenty-three'
3 user1 'the reason of life'
4 user2 'twenty-three'
5 user2 '303 rulz'
6 user3 NULL
I would like to get this:
1 user1 '50 - twenty-three - the reason of life'
2 user2 'twenty-three - 303 rulz'
3 user3 ''
If there is a function to sum values, why there isn't one to sum strings
i.e. concat strings. Or how should i use it?
I tried:
SQL>SELECT Table1.name, CONCAT(Table3.txt) FROM Table1 left join Table2 on
Table1.uid=Table2.uid left join Table3 on Table2.c=Table3.c group by
Table1.name;
1 user1 '50'
2 user2 'twenty-three'
3 user3 NULL
3 rows in set (0.00 sec)
server version is 3.22.32
