The following statement fails with the sqlite wrapper:
cursor = connection.cursor()
cursor.executemany("insert into test (name) values(%s)",[])
It raises an IndexError? exception when the code tries to pick up the first element in the parameter list.
The code is in the following statements in the file django\db\backends\sqlite3\base.py :
def executemany(self, query, param_list):
query = self.convert_query(query, len(param_list[0]))
return Database.Cursor.executemany(self, query, param_list)
An obvious fix is as follows:
def executemany(self, query, param_list):
try:
query = self.convert_query(query, len(param_list[0]))
return Database.Cursor.executemany(self, query, param_list)
except IndexError:
# No parameter list provided
return None
