-

i new mysql , need query here sample data columns: 

modelid styleid sequence 19463   316811  0 19463   316812  1 19463   316813  2 19463   316814  3 19463   316920  4 19463   316921  5 19727   318010  0 19727   318011  2 19727   318012  1 19727   318013  3 19884   320053  0 19884   320054  1 19884   320055  2 19884   320056  3 19998   321302  0 19998   321303  1 19998   321304  2 19998   321305  3 19998   321306  4 19998   321307  5 19998   321308  6 19998   321309  7

i need 1 styleid every modelid, preferably sequence of 0 or 1, sequence not matter, can random.

the best result this, cant use sequence = 0 clause though:

modelid styleid sequence 19463   316811  0 19727   318010  0 19884   320053  0

thanks

try this

select modelid, max(styleid),min(sequence) mytable  group modelid
