Hi everyone

     I have tried to remove duplicates from my data set using sql distinct, max, etc but unfortunately it did not work.

Have:

COD_ACOD_B
11002200
110023010
1100215400

Want:

COD_ACOD_B
11002200

     It doesn’t matter with cod B will be chose in table want, what I really need is to update from tree observations, to just one but keeping cod_b in the result.

     I have tried many SQL solutions, like group by, distinct etc...

Thanks in advance

Regards
