Sybase Database

Given: A Sybase SQL table arranged as "Field1 | Field2 | Field3 ...."

Each Field1 will have one or more Field2's associated with it as shown below.  Field3 is a timstamp.

Field1 | Field2a | Field3
Field1 | Field2b | Field3
Field1 | Field2c | Field3

Selecting a given Field1 would return three rows because of the three different Field2 values.  I need to return exactly one row for each unique Field1.  That row must be the one with the most recent timestamp.

Thank you
