Inserting calculated fields in database queries

Question

I have just changed from using StarOffice version 7 to version 8.
I am having difficulties in creating a calculated field in a query.
Would anyone have some ideas for me to follow?
Thanks - Dan

1.  Order as a column name could be problematical as it might conflict with the SQL 'ORDER BY'.  Wrapping it in square brackets should cater for this.
2.  You are missing some spaces.  
3.  The use of the arithmetical + operator could be problematical with dates as the string expressions, which might be interpreted as arithmetical expressions.  The + operator is used rather than the ampersand concatenation operator to suppress
Nulls, but that's not the case here.  
4.  As you are only returning columns from one table you do not need to qualify the column names with the table name.  
5.  Defining a range as on or later than the start date and before the day following the end date is more reliable as it allows for rows with date/time values on the last day of the range with a non-zero time of day element, something you cannot rule out
with complete confidence unless you have taken specific steps in the table definition to disallow such values.
So taking these points into account:
strSQL6 = _
        "SELECT [Order], [OperWorkCenter], [Created on], " & _
        "[Actfinish date]," [Actfinish date]-[Created on] AS Delta " & _
        "FROM [WOMP Work Orders] " & _
        "WHERE [Created on] >= #" & FStartDate$ & "# " & _
         "AND [Created on] < #" & FEndDate$  & "# + 1"
The FStartDate$ and FEndDate$ values must of course be in US short date format or an otherwise internationally unambiguous format such as the
ISO standard date format of YYYY-MM-DD.
