    Hi Everyone, new to the board...glad to have found it.

    I'm trying to calculate a numeric value based on queries from two different tables.

    this is query number one:

    SELECT SUM(ROOMREVENUE) AS 'ROOM REVENUE' FROM RPT_HOTEL_STATS WHERE PROPERTY = 'DELSOL'

    AND STAT_DATE > '2007-12-31 00:00:00.000'

    AND STAT_DATE <= DATEDIFF(day, 0, getdate())

    this is query two:

    select SUM(NUMROOMS) FROM AVAILABILITY_ROOMS WHERE RES_DATE > '2007-12-31 00:00:00.000'

    AND RES_DATE <= DATEDIFF(day, 0, getdate())

    I want to divide query result 1 by query result 2!!

    can anyone help with syntax?

    Welcome aboard... first, here's one answer two your problem...

    SELECT

    (

    SELECT SUM(ROOMREVENUE) AS 'ROOM REVENUE' FROM RPT_HOTEL_STATS WHERE PROPERTY = 'DELSOL'

    AND STAT_DATE > '2007-12-31 00:00:00.000'

    AND STAT_DATE <= DATEDIFF(day, 0, getdate())

    )

    /

    (

    select SUM(NUMROOMS) FROM AVAILABILITY_ROOMS WHERE RES_DATE > '2007-12-31 00:00:00.000'

    AND RES_DATE <= DATEDIFF(day, 0, getdate())

    )
