    Is there a simple way to get a single row table with variable numbers of columns to output with 2 columns?

    i.e.

    colA colB colC

    1 5 23

    colA 1

    colB 2

    colC 3

    and handle an extra column easily:

    colA colB colC colD

    1 5 23 743

    colA 1

    colB 2

    colC 3

    colD 743

    "Simple" is a relative term. Which version of SQL Server are you using? A relatively simple version would entail reading syscolumns for the table and then dynamic SQL to construct a query from the results.
