  • Reader Feedback and Insights: One-Row Table Still Needed

    December 6, 2002 Timothy Prickett Morgan

    Hey, Ted:

    In the article, “Overlooking the Obvious,” which published in the November 8 issue of Midrange Guru, you asked the question, “does anybody have a use for a one-row, one-column table?”

    I’ll still need one for the near future.

    • I don’t have a C compiler or interactive SQL, so I’m stuck without variables.
    • I run a lot of test scripts initially in Operations Navigator (cwbundbs), and it’s handy for testing the duration of things:
    select 'start',now() from onerec;
    update some long thing with a few statements;
    select 'end',now() from onerec;
    

    ONEREC is my one-row table. I created it before you published your tip.

    It’s also handy to have a one-row table when I need to test an ODBC or OLE or DDM connection in some fashion. It’s faster and easier to display or update ONEREC than a real table.
