database - MySQL Join on 3 Tables -


I have a problem and do not have to decide any clue or starting point at that point:

My Near three fields with the following fields (I am limited to the important fields): 

  Table 1 Table 2 Table 3 IDPP has subscribed   
 What do I do The most is the field of Table 1 and Table 3, the table 1 field is linked with Table 3 on table3 field through idsp and table2.  
 As I said, I do not have any starting point ... any help?  
 Thank you, Saska   
 
 
  select t1 *, T3 Table1 t1 included in internal table 2 t2 on t1.idsp = t2.idsp Internal incoming table 3 T3 T2DD = T3DD   
 Just one after the other use to be.
