While looking at some of the websocket methods that stack exchange offers, I wanted to save a few data points into a MySQL database. However, when I attempt to run an executemany
command, I get the following error:
_mysql_exceptions.OperationalError: (1241, 'Operand should contain 1 column(s)')
While looking around SO, I found many examples of this error, but they have dealt with removing parenthesis on SELECT
statements. I'm not using a SELECT
. I'm attempting to INSERT
.
A short, contained, example of my code looks like this:
import MySQLdb as mdb
db = mdb.connect(host='localhost',user='myuser',db='qs',passwd='mypass',use_unicode=True,charset='utf8')
cur = db.cursor()
db_qry = """INSERT IGNORE INTO questions (id, site_base, title, body_sum, tags, last_act_dt, url, owner_url, owner, api_site) values (%s,%s,%s,%s,%s,%s,%s,%s,%s,%s)"""

cur.executemany(db_qry, parms)
cur.commit()
Am I using the executemany
incorrect? Or missing another aspect of the parms
list that I need to clean before passing to executemany
?
