Yes that is true '' or empty strings are not nulls or integers... I
suggest replacing the '' with the word null, this will sort out the
issue based on the query you specified.

I would rename the MyISAM tables using phpmyadmin or using SQL and sort
out the Database to run case sensitive in the first place like the ANSI
standard.

Or much better still mysqldump the entire MySQL server into a file
"textfilename.sql", sort out the table names etc... using a good text
editor, place a drop table if exists before each create table entry,
save the file then run mysql -uroot -p < "textfilename.sql" to recreate
all of the databases including data with tablenames in the correct case...

Maybe I am just too fussy...

Only if you live in an all windows world... "Compatability is a bitch it
demands the use of standards, the little things which M$ don't adhere to
very well" ;-)
