In Oracle, I can use the analytic ROW_NUMBER function to assign sequence numbers to output rows, re-starting the sequence as certain values change (e.g., there's a separate count for each deptno in this example:) SELECT deptno , ename , ROW_NUMBER () OVER ( PARTITION BY deptno ORDER BY ename ) AS seq FROM scott.emp ORDER BY deptno , ename; Output: DEPTNO ENAME SEQ ---------- ---------- ---------- 10 CLARK 1 10 KING 2 10 MILLER 3 20 ADAMS 1 20 FORD 2 20 JONES 3 20 SCOTT 4 20 SMITH 5 30 ALLEN 1 30 BLAKE 2 30 JAMES 3 30 MARTIN 4 30 TURNER 5 30 WARD 6 14 rows selected. Is there something similar in SQL Server?

Thanks. We'll let you know when a new response is added.

SQL Server 2005 introduced that same functionally using the same syntax.

If you are using SQL 2000 or prior there is no equivalent.
