Hi All

I basically I have 3 tables T1 T2 and T3 (Look up table)


Col11     Col12     

aa     888     
aa     444     
bb     666
bb     447
bb     478
bb     999


Col21     Col22     Col23

123     hhh     lll
123     hhh     ppp
123     hhh     uuu
345     ghg     kkj
345     ghg     rer
475     hhh     uyy


Col31     Col32     

aa     123
aa     345
aa     564
bb     564
bb     475

I need to find out whether all the correspondance values(T3.Col31) of T1.Col11 are there in T2. If not what are the missing
I have this T3 lookup table to match between T1 T3

As a above data I need to get the following out put

T1.Col11     T3.Col32     T2.Col22     T2.Col23

aa          123          hhh          lll
aa          123          hhh          ppp
aa          123          hhh          uuu
aa          345          ghg          kkj
aa          345          ghg          rer
aa          564          NULL          NULL

What sort of query I can use to get the result
