I have a problem- I have data that looks something like this:

ID#, lastname1, firstname1, lastname2, firstname2

and I'd like output similar to:

ID#1 lastname1, firstname1
ID#1 lastname2, firstname2
ID#2 lastname1, firstname1
ID#2 lastname2, firstname2

How can I do this without moving my data into new tables or using temp-tables?

Thanks,

Mark

With a UNION...

SELECT ID, lastname1, firstname1 FROM myTable
UNION ALL
SELECT ID, lastname2, firstname2 FROM myTable
ORDER BY ID

Small modification of Ajarn code

(Select * from (SELECT ID, lastname1, firstname1 FROM myTable
UNION ALL
SELECT ID, lastname2, firstname2 FROM myTable ) T
ORDER BY ID

Madhivan, why the modification? The ORDER BY in my clause does not get applied until after the union is performed anyway. Is this a difference in versions? Or just for clarity of code?

Yes

If he use Order by in First statement, he will get error

SELECT ID, lastname1, firstname1 FROM myTable
ORDER BY ID
UNION ALL
SELECT ID, lastname2, firstname2 FROM myTable

Yep! That's how I learned about it.
