column 'pin' is an 5-digit integer auto_increment primary key.

What i want is to insert a new record or update the existing one, if 'pin' =
column's value exist. The following statement fails.

[code]
cursor.execute( '''INSERT INTO counters(page, hits) VALUES(%s, %s) RETURNIN=
G (pin)=20
                        ON DUPLICATE KEY UPDATE hits =3D hits + 1''', (html=
page, 1) )
[/code]=20

Also except from the inserting/updating job, i also need 'pin' colum's valu=
e to be extracted from the above statement so to be used to subsequent stat=
ement like the following. This is not happening, hence the following statem=
ent have no way to find 'pin' column's value which is to be used as a param=
eter to it.

[code]
cursor.execute( '''UPDATE visitors SET hits =3D hits + 1, useros =3D %s, br=
owser =3D %s, date =3D %s WHERE pin =3D %s AND host =3D %s''', (useros, bro=
wser, date, pin, host))=20
[/code]

Can someone correct this please and explain?
