| I am subtracting the values of 2 fields:SELECT(a.Days_Since - a.Total_Days) as Days_Since FROM tblCall aThe Field Total_Days is either NULL or contains a number. If Total_Days contains a number it will work fine and return a value but if Total_Days is NULL it will return no value even if Days_Since contains a value.Anyone know what I'm missing? |
