Hi,
I need some help on a particular sql statement syntax. Consider the following
tables:
T1:
ID, NAME
1, John
T2:
REFID, COUNT, TYPE
1, 9, B
1, 5, U
1, 8, T
I have the following statement:
select T1.NAME, group_concat(T2.COUNT), group_concat(T2.TYPE) from T1 left join
T2 on T1.ID=T2.REFID;
4 matches
