Seems odd there would be any problem if the XMittalDate were truly a DATE data type column as originally stated. In that case, the format should be moot; i.e. assuming the variables assigned the literals of format mm/dd/yyyy are properly recognized as the expected date values. I would expect the undesirable effect only if the query performed an implicit cast of the XMittalDate column to a character string.?

You're right Rick. I actually just discovered that a few minutes

I'll find a good date conversion routine I can copy from on Google for my PHP script to take care of that.

Thanks for pointing that out! It was only luck that I happened to
go past year end checking it just now. I wasn't even looking for
that, I was testing something else when I discovered it. I could
just as easily have missed it until I got a lot deeper into
this.

This doesn't directly address your question but I believe you have a bug in your statement. Given the data example you have
you will have issues with your date range if it is truly in MM/DD/YYYY format. For example, if you wanted records crossing
a year end your end date is less than your start date.

We have a lot of dates like this and had to create a user
defined function to convert them to ISO for comparison. It can
be done without the UDF but it's pretty ugly.

I want to select a group of dates based on date range in a
PHP app from a MySQL database.

Assume the table name is xmittalheader and the date field is named: XMittalDate and is in the format in the MySQL table
like this: 11/02/2009

Further assume $startDate and $endDate are being brought into
the PHP via a POST from a form.

Would this be the correct syntax?

$results = mysqli_query($db, "SELECT * FROM xmittalheader
WHERE XMittalDate BETWEEN ".$startDate." and ".$endDate);
