I have a strange data mismatch error

S

scubadiver

I am trying to create a "Totals" query based on another query. The source
query has a set of calculations between dates and I want the "Totals" query
to give me the number of records grouped by time taken (basically a frequency
distribution).

Neither query has criteria expressions yet I am getting a "data type
mismatch in criteria expression" error and I can't see why.

Source query SQL:

SELECT tble_Query.QueryID, tble_Query.Qry_ELS, tble_Query.Qry_Status,
tble_Query.CreInv, tble_Query.Cont_InvName,
WorkingDays2([SLA_Date1],[SLA_Date2]) AS Logged,
WorkingDays2([SLA_Date2],[SLA_Date3]) AS Timetaken,
WorkingDays2([SLA_Date1],[SLA_Date3]) AS Completed,
WorkingDays2([SLA_Date1],[SLA_Date4]) AS Preventative,
WorkingDays2([SLA_Date1],[SLA_Date5]) AS Authorised,
WorkingDays2([SLA_Date1],[SLA_Date6]) AS Billing,
WorkingDays2([SLA_Date1],[SLA_Date7]) AS Completion
FROM tble_Query;

Second query SQL:

SELECT [SLA Master].Timetaken, Count([SLA Master].Timetaken) AS
CountOfTimetaken, [SLA Master].Qry_Status
FROM [SLA Master]
GROUP BY [SLA Master].Timetaken, [SLA Master].Qry_Status;

My workingdays function calculates the number of days between two dates
excluding weekends and public holidays. So I am not sure whether your example
would work.

You probably need to typecast the return value from the function in the
query.

What is the return value from the function? Variant? Long?

You may need to use:
CLng(WorkingDays2([SLA_Date1],[SLA_Date2])) AS Logged,
etc, or:
CLngNz(WorkingDays2([SLA_Date1],[SLA_Date2]),0)) AS Logged,
