Question

I have a requirement to determine the maximum Id int value for a set of tables in my database. The column is always ‘Id’ and is the primary key. Is there a simple way I can make this determination without resorting to a cursor or looping?

Answer 1

SELECT MAX(MaxId) As MaxId FROM (
    SELECT MAX(id) AS MaxId FROM Table1
    UNION ALL
    SELECT MAX(id) AS MaxId FROM Table2
) AS T1
