The way you do it, yes.
Is that email column a BLOB or a BINARY VARCHAR? If not,
why on earth do you do LOWER() on it? And do you have an
index on the column?

Hi Monty,
I've been experimenting with ENUM NOT NULL columns without a default

assigns one. If the column may take NULL as a value, the default value is
NULL. If the column
You were close to it.
But he way to get the last inserted item on AUTO_INCREMENT field is for
example:
id = mysql_insert_id(&mysql);
printf("The last insert is: %d\n", id);
And mysql is what was return to you when you open your connection to the
database.

If you specify the keyword IGNORE in an INSERT, any rows that duplicate
an existing PRIMARY or UNIQUE key in the table are ignored and are not
inserted.
But the last_insert_id() function still appears to increment by one
in situations when the query is not adding any new information to
the tab
MySQL is not Oracle ... and that's a good thing, too! :-)

You didn't mention how large your table is or if the email and cust fields
are part of an index.
In many situations, the results you are seeing make perfect sense to me. If
email is a part of an index then the LOWER function may need to be performed
on each value of email in the index before the

This behaviour is described in http://www.mysql.com/doc/B/u/Bugs.html.

Hi there,
Is it expected that using the LOWER function should greatly increase query
time? Or is there a MySQL setting that can help speed it up? Below are the

With MySQL, there is not (yet) a way to do this with a single

therefore you normally would seldom need a command such as the one
