Another Query Modification Question

I use this query...

TRANSFORM Sum(Nz([PC Vol]/2,0)+Nz([BD Vol]/2,0)+Nz([MM Vol]/2,0)) AS
Expr1
SELECT OCC_Data.underlying, Sum([PC Vol]/2)+Sum([BD Vol]/2)+Sum([MM
Vol]/2) AS OCC_Vol
FROM OCC_Data
WHERE (((OCC_Data.date)=[EnterDate yyyymmdd]) AND ((OCC_Data.Product)
In ('OSTK','OIND'))) and OCC_Data.underlying Not In
('VIX','SPX','OEX','DJX')
GROUP BY OCC_Data.underlying
PIVOT OCC_Data.exchange In ("A","B","C","I","P","Q","W","X","Z");


Which prompts me for a date. Is there a way to change the query so
when the user gets prompted to enter a date, that the can enter
20110410 for April 19 2011 OR enter 201104 and get all records for
April 2011.


Thanks in advance.

Assuming that the date field is of Text datatype (as appears to be the case)
then yes:

TRANSFORM Sum(Nz([PC Vol]/2,0)+Nz([BD Vol]/2,0)+Nz([MM Vol]/2,0)) AS
Expr1
SELECT OCC_Data.underlying, Sum([PC Vol]/2)+Sum([BD Vol]/2)+Sum([MM
Vol]/2) AS OCC_Vol
FROM OCC_Data
WHERE (((OCC_Data.date) LIKE [EnterDate yyyymmdd or yyyymm] & "*") AND
((OCC_Data.Product)
In ('OSTK','OIND'))) and OCC_Data.underlying Not In
('VIX','SPX','OEX','DJX')
GROUP BY OCC_Data.underlying
PIVOT OCC_Data.exchange In ("A","B","C","I","P","Q","W","X","Z");

This might be a bit awkward: if the user enters 2011 they'll get all records
for that year, if they enter 20 they'll get all records from the 21st century,
if they enter a blank they'll get all records.

I'd probably use a Date/Time field for the date field (and would *NOT* use the
reserved word Date as a fieldname) and a Form to collect criteria, rather than
a prompt.

Thanks. I should have mentioned that the date format is number.

Seems like the "Like" operator does not work on numbers ?

Is there a similar one that will work on a number ?

Number, eh? Ouch.

In that case you'll need to parse the input:

WHERE (((OCC_Data.[date])>= IIF(Len([EnterDate yyyymmdd or yyyymm:]) = 6,
100*Val([EnterDate yyyymmdd or yyyymm:])), Val([EnterDate yyyymmdd or
yyyymm:])) AND (OCC_Data.[date]< IIF(Len([EnterDate yyyymmdd or yyyymm:]) = 6,
101*Val([EnterDate yyyymmdd or yyyymm:])), Val([EnterDate yyyymmdd or
yyyymm:]) + 1)

Ugly as sin, because of the nonstandard storage of the date. Again, your life
would be much easier if you used a Date datatype.

Other options would be

Inefficient (Force the number to a string] - cannot use indexes
WHERE [Date] & "" Like [Enter Date String] & "*"

More efficient )one calculation to get the beginning and ending of the date
numeric range.
WHERE [Date] >= Val(Left([Enter Date String]&"00000000",8))
AND [Date] <= Val(Left([Enter Date String] & "99999999",8))

That means you can return data by Century, decade, year, month, or day.

When I run it, I get prompted for only one data entry. and I get no
results.

Is my syntax incorrect ?

The two parameters must have different names. Sorry, I was unclear

TRANSFORM Sum(Nz([PC Vol]/2,0)+Nz([BD Vol]/2,0)+Nz([MM Vol]/2,0)) AS
Expr1
SELECT Sum([PC Vol]/2)+Sum([BD Vol]/2)+Sum([MM Vol]/2) AS OCC_Vol
FROM OCC_Data
WHERE (OCC_Data.date>=Val(left([EnterStartDate yyyymmdd] & "00000000",8))
And OCC_Data.date<=Val(left([EnterEndDate yyyymmdd] & "99999999",8)) And
((OCC_Data.Product) In ('OSTK','OIND')) And OCC_Data.underlying Not In
('VIX','SPX','OEX','DJX'))
GROUP BY date
PIVOT OCC_Data.exchange In ("A","B","C","I","P","Q","W","X","Z");
