#336 Wrong exception type generated
According to the Python DB API 2.0 (http://legacy.python.org/dev/peps/pep-0249/#integrityerror), an IntegrityError should be raised when a required (NOT NULL) parameter is missing, but instead an OperationalError is raised.
Tested with mysql-python 1.2.3.
import MySQLdb import MySQLdb.cursors db = MySQLdb.connect(host="localhost", user="root", db="test", sql_mode="traditional") db.autocommit(False) cur = db.cursor() cur.execute("DROP TABLE IF EXISTS `test`") cur.execute("CREATE TABLE `test` (`integer` bigint(20) NOT NULL, `desc` varchar(255) NOT NULL)") db.commit() cur.execute("INSERT INTO `test` (`integer`) VALUES (%s)", (1, )) db.commit()
$ python /tmp/test.py Traceback (most recent call last): File "/tmp/test.py", line 12, in <module> cur.execute("INSERT INTO `test` (`integer`) VALUES (%s)", (1, )) File "/usr/lib/python2.7/dist-packages/MySQLdb/cursors.py", line 174, in execute self.errorhandler(self, exc, value) File "/usr/lib/python2.7/dist-packages/MySQLdb/connections.py", line 36, in defaulterrorhandler raise errorclass, errorvalue _mysql_exceptions.OperationalError: (1364, "Field 'desc' doesn't have a default value")
