SyntaxError: invalid syntax

any idea why?

Thanks for the help in advance

Update #2, I have removed the double single quote on the "categories_name", but now even

import MySQLdb  

conn =  MySQLdb.connect(host="localhost",port=22008,user="cholestoff",passwd="whoami",db="mydatabase")  
cursor = conn.cursor()  

## Find mysql version  
cursor.execute ("SELECT VERSION()")  
row = cursor.fetchone()  
print "server version:", row[0]  

website1g = "http://www.triman.com"  
business_nameg = "Triman Sales Inc"  
business_address1g = "510 E Airline Way"  
business_cityg = "Gardena"  
business_stateg = "CA"  
business_zipcodeg = "90248"  
phone_number1g = "(310) 323-5410"  
phone_number2g = ""  

cursor.execute ("""
    INSERT INTO yellowpages(categories_name, business_name)
    VALUES ('%s','%s')
""", ('gas-stations', business_nameg))              

cursor.close()  
conn.close()  

still gotten this error

Thanks again for the help

I think your problem is here:

''gas-stations''

This gives a syntax error. You probably want to use one set of quotes:

'gas-stations'

If you want to insert the value 'gas-stations' into the database including the quotes then you can either escape the quotes or surround the string with double-quotes instead of single quotes:

"'gas-stations'"

The reason why the "up arrow" is pointing at the wrong place is because your lines are so long that it is wrapping on your console. Make your lines shorter, or widen your console window to see where the error really is.

For your second problem, you need to lose all those single-quote characters in your VALUES clause ... should look like VALUES (%s,%s) not like VALUES ('%s','%s').

The general rules are very simple: for each parameter, have one place-marker (in the case of mySQLdb this is %s) in your SQL statement, and supply one Python expression in your tuple of parameters. Then lean back and let the interface software do the right thing for you. This includes quoting strings properly. Don't try to do it your self. In particular, string expressions should be exactly what you expect to retrieve later.

Example: The business_name of a gas station is "O'Reilly's Pump'n'Go" as a Python string constant. This will end up in the constructed SQL as ...VALUES(...,'O''Reilly''s Pump''n''Go',... without you having to think about it.

You can't use doubled single-quotes (i.e. ''gas-stations'') - use either just single single-quotes ('gas-stations'), or actual double quotes ("gas-stations").

I also got such error and I solved it by replacing '%s' by %s under values.

    VALUES(%s,%s)
