[Tutor] Placeholder in string (MySQL instruction)

["Héctor Villafuerte D."]

Hi all,
I'm loading some files into MySQL tables. This function is working fine:

def load_data(proc):
    """Loads *.proc files into MySQL @ localhost."""
    cursor.execute("""LOAD DATA INFILE %s INTO TABLE traf_internat 
FIELDS TERMINATED BY ''""", (proc,))

BUT, I would like to pass the table name as an argument also... 
something like this:

load_data(os.getcwd()+'\\'+'ldia.proc', 'traf_internat')

def load_data(proc, table):
    """Loads *.proc files into MySQL @ localhost."""
    cursor.execute("""LOAD DATA INFILE %s INTO TABLE %s FIELDS 
TERMINATED BY ''""", (proc,table))

Unfortunately, this won't work:

Traceback (most recent call last):
  File "c:\Python23\progs\ttp\ttp_build.py", line 88, in ?
    ttp_mysql.load_data(os.getcwd()+'\\'+'ldia.proc', 'traf_internat')

SQL syntax.  Check the manual that corresponds to
your MySQL server version for the right syntax to use near 
''traf_internat' FIELDS TERMINATED BY ''' at line 1")

Thanks in advance for your help,
Hector
