Question SQL Query Help
Consider the scenario,

Col 1 Col 2 Col3 ...
A 1 100 ...
A 1 100 ...
A 3 100 ...
B 4 101 ...
B 4 101 ...
B 4 101 ...

I need to eliminate duplicates based on Col 1-3 and print other columns,
Col 1 Col 2 Col3 ...
A 1 100 ...
A 3 100 ...
B 4 101 ...

Can this be acheived using a query?
