    Your question states MySQL & SQL Server so here is both:

    SQL Server datediff function:

    SELECT ID, DATEDIFF(DAY, GETDATE(), CONVERT(DATETIME, sDate)) FROM TABLE

    MySQL datediff function:

    SELECT ID, DATEDIFF(CURDATE(), STR_TO_DATE(sDate, '%c/%d/%Y')) FROM TABLE

    This uses the STR_TO_DATE function to convert the varchar to a date and assumes that the format of your date strings is in the format month/day/year.
