TypeError: not all arguments converted during string formatting in psycopg2

问题

When I run the below code with psycopg2:

cur.execute(
    """INSERT INTO logmsg (msg_type, file, msg) VALUES %s;""",
    ["Error", str(file), str(sys.exc_info()[0])])

I get the following error:

TypeError: not all arguments converted during string formatting

Can someone help me with this?

回答1:

VALUES needs a list of values enclosed in brackets:

cur.execute(
    """INSERT INTO logmsg (msg_type, file, msg) VALUES (%s, %s, %s);""",
    ["Error", str(file), str(sys.exc_info()[0])])

Do not forget to commit the transaction.
