You would use a UNION query.
SELECT YourTable.Record, Account1 FROM YourTable
UNION
SELECT YourTable.Record, Account2 FROM YourTable
UNION
SELECT YourTable.Record, Account3 FROM YourTable;
I didn't use any ORDER BY clause anywhere, nor do I know if you will get duplicate records without knowing more about the real data. You might need a distinct predicate on each of the individual select statements.
The more we hear silence, the more we begin to think about our value in this universe.
