Question

i have a problem and at that point no clue or starting point how to fix:

I have three Tables with the following fields (i have limited to the important fields):

table1    table2        table3
idsp        idsp          did
customer    did

What i need is most fields of table1 and table3, table1 is combined to table2 through field idsp and
table2 with table3 on field did.

As i told, i have no starting point… Anyone help?

Thanks,
Sascha

Answer 1

select t1.*, t3.* from 
table1 t1 
inner join table2 t2
  on t1.idsp = t2.idsp
inner join table3 t3
  on t2.did = t3.did

Just carry on using joins one after the other.
