Hi Patrice
I would try some brackets.
Something like this should work
SELECT * FROM listings WHERE listing_state = 'DC' AND listings.listing_show
='y' AND ( listings.cat1 = 23 OR listings.cat2 = 23 OR listings.cat3 =
23 )

Thanks for the pointer. Digging out reference books to learn how to do a join.

Which probably means not so much to someone who doesn't even know what a join
is :-)
Have a look at http://www.w3schools.com/sql/sql_join.asp .

Hey, welcome to the lists,
Be mindful that your query is using 2 tables and 'SELECT *'.

You could make the column a unique key...that would prevent duplicates from
being entered. Then if you want to be able to try inserting duplicates (like
if you don't want the query to fail on duplicate attempts), you could do
INSERT IGNORE INTO myTable ...
Check http://www.mysql.com/doc/en/CREATE_
Add a UNIQUE INDEX to the table you are inserting to. You will then get
an error if you try to insert a second time with the same values.
Alternativly you could use perform a select and then an insert within
the same transaction, determining whether something exists in the db
before inserting. Th
If you wanted to use MyISAM tables and peform an initial select to
determine whether you should insert, you could lock the table you would
be selecting/insert from. 'LOCK TABLES table_name WRITE' Don't forget
to unlock the table when you are done 'UNLOCK TABLES', otherwise you
will likely have de
ALTER TABLE table_name DROP col_name
http://www.mysql.com/doc/en/ALTER_TABLE.html
So...
mysql> use hitcounter;
mysql> ALTER TABLE info DROP count;
Assuming info is the table name and count is the column you'd like to drop.

Assuming that you have a table called 'test' where there are three columns
'a', 'b' and 'c'.
Now you have 'a'+'b' as unique but neither only 'a' nor 'b'.
To specify that, define a and b both combined as primary key for the table,
as in the following statement:
CREATE TABLE `test` (
`a` TINYINT

Not sure what the "load data local infile" thing is, but I always
load text files from the command line like this (on Red Hat linux):
% mysql -u some_guy -p some_db < /full/path/to/file.txt
