Is there a way to split the results of a select query into two equal halfs?

Question

I need a solution for a select query in Sql Server 2005.

I\'d like to have a query returning two ResultSets each of which holding exactly half of all records matchin

You could use these two queries:

SELECT * FROM (
    SELECT *, ROW_NUMBER() OVER (ORDER BY TheID) AS rn FROM TheTable
) T1
WHERE rn % 2 = 0

SELECT * FROM (
    SELECT *, ROW_NUMBER() OVER (ORDER BY TheID) AS rn FROM TheTable
) T1
WHERE rn % 2 = 1
