Join them; it only takes sql error a minute: Sign up Correct exception handling with python MySQLdb connection up vote 6 down vote favorite 1 I created a small/basic python script to insert data into a MySQL database. 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 sql error handling had (see below) was right - it 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

Join them; it only takes a minute: Sign up Trapping MySQL Warnings In Python up vote 13 down vote favorite 2 I would like to catch and log MySQL warnings in Python. For example, MySQL issues a warning to standard error if you submit 'DROP DATABASE IF EXISTS database_of_armaments' when no such database exists. I would like to catch this and log it, but even in the try/else syntax the warning message still appears. The try/except syntax does catch MySQL errors (eg, submission of a typo like 'DRP DATABASE database_of_armaments'). I have experimented with <
