#4765: sqlite3 executemany wrapper fails with empty parameter list
-------------------------------------+--------------------------------------
Reporter: [EMAIL PROTECTED] | Owner: adrian
Status: new | Component: Database wrapper
Version: SVN | Keywords: sqlite3
Stage: Unreviewed | Has_patch: 0
-------------------------------------+--------------------------------------
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. [[BR]]
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
}}}
