real number returned with comma as decimal delimiter

Hi,
I have CF9 installed on W7 using an Access database.
In a table I have a currency value of -488.7

The windows is French, but I have set the delimiter for both the decimal values AND currency values to dot instead of comma.

Though I get this error in CF:

The value -488,7 cannot be converted to a number.

CF is receiving the value with a comma instead of a dot.

- If I browse the table under Access, the value is correctly displayed with a dot.

- If I modify the column type to teTEXT instead of real or currency, the value is converted to text with a dot, and there is no error in CF.

Obviously a conversion from dot to comma is made in some other layer, but where?

I've checked in the ODBC connection and found nothing.

Any idea?

Correct answer Claude1

>>If you do a simple query and cfdump the result, do you get a period or comma?

Yes I do.

But I finaly found the problem.

The query is produced by a UNION, and in one of the sub SELECTs, the column was set to '0' instead of 0. This tiggered a converstion to text for the same column in the next SELECT, probably in the ODBC driver, and this conversion implied the use of a comma instead of a dot. For some unknown reason, it follows the rule for French because the version of Windows is French, but bypasses the settings in Windows.

You mean you had a query like this:

select some_text_field, etc

union

select some_numeric_field, etc

that didn't error out?

I just tried that in redbrick and sql server and in both cases, they crashed.
