I included some error handling - mainly to close the connection and/or prevent hanging connections in the case of an error (...but also to ignore some errors). I thought what I had (see below) was right - it pymysql error handling seemed to be working okay. But occasionally I have been getting "Too many connection" errors - which I assumes means I am not actually closing the connection correctly at all (or perhaps error handling isn't right). conn=MySQLdb.connect(host=####, user=####, passwd=####, db=####) curs=conn.cursor() try: curs.execute(sql) conn.commit() except MySQLdb.Error as e: if e[0]!= ###: raise finally: curs.close() conn.close() (I also tried without finally:) The other (I think important) point is that it is that the MySQL database uses an InnoDB storage engine. This is the first time I have used InnoDB engine and perhaps there are some differences to MyISAM that are relevant here, that I am not aware of (like conn.commit(), but for an error).... That seems to be the source of all my other problems! Thanks in advance python error-handling innodb mysql-python share|improve this question edited Feb 14 '14 at 3:34 asked Feb 12 '14 at 7:15 djmac 1591413 You should remove the conn.close() from the try body, as it will always be called within the finally body. Other than that, it looks like you're releasing your connections properly. –lanzz Feb 12 '14 at 7:51 Th
