Have you tried using

"Select * from table where x like '" & [ucase, lcase]('y') & "';"

Just a thought.

You can use the StrComp("Y", "y", 0) = 0 for binary comparison

Straight from an access 2000 query,

SELECT USystblSecurityGroups.strGroupName, StrComp([strgroupname],"grpMKCITLibrary",0) AS Expr1
FROM USystblSecurityGroups
WITH OWNERACCESS OPTION;

If using a form to make the comparison, look at the module behind the form in the general section it will probably have a line
'Option Compare Database'
Change this to read 'Option Compare Binary' then a will not = A

Further to my previous answer, if working in a query you could use the following built in function to make your comparison

iif(asc(Field1)=asc(field2),"Match","Nomatch")

What is CFM? If you are using an ODBC driver to select the data then you will have to code it in CFM as JET doesn't support Case sensitive queries. Check out the MS KB article Q209674 this advises the use of ASC() or STRCOMP both of which are VBA functions.

The only thing you can do is to select the data through the ODBC driver which is not case sensitiy then process the results so you can eliminate the case sensitive stuff.

Ciao labambina,

you can use the StrComp function for this.

From Access 97 Help
<
StrComp Function

Returns a Variant (Integer) indicating the result of a string comparison.

Syntax

StrComp(string1, string2[, compare])

The StrComp function syntax has these named arguments:

Part     Description
string1     Required. Any valid string expression.
string2     Required. Any valid string expression.
compare     Optional. Specifies the type of string comparison. The compare argument can be omitted, or it can be 0, 1 or 2. Specify 0 (default) to perform a BINARY COMPARISON. Specify 1 to perform a textual comparison. For Microsoft Access only, specify 2 to perform a comparison based on information contained in your database. If compare is Null, an error occurs. If compare is omitted, the Option Compare setting determines the type of comparison.
Return Values

If     StrComp returns
string1 is less than string2     -1
string1 is equal to string2      0
string1 is greater than string2      1
string1 or string2 is Null     Null

>

So in your case you should use
Select * from table where StrComp([X],'Y',0) = 0 if you want only 'Y'
Select * from table where StrComp([X],'y',0) = 0 if you want only 'y'

Good luck,
YP

Nic;o, the user is doing the query in cold fusion through ODBC to jet, I don't think any of this has addressed the issue from Cold Fusion as you can't call Access function through ODBC.
