[Bug 718860] [NEW] Call to fetchone after LAST_INSERT_ID() does not clear cursor
Public bug reported:
Client: mysql Ver 14.12 Distrib 5.0.77, for redhat-linux-gnu (i686) using readline 5.1
Server: Server version: 5.0.77 Source distribution
Python 2.7
oursql-0.9.2-py2.7-linux-i686
When calling LAST_INSERT_ID() cursor.fetchone() must be called twice, or
else a new call to cursor.fetchone() will return None:
>>> cursor.execute("INSERT INTO users (username) VALUES ('test')")
>>> cursor.execute("SELECT LAST_INSERT_ID()")
>>> print cursor.fetchone()
{'LAST_INSERT_ID()': 7L}
>>> cursor.execute("INSERT INTO users (username) VALUES ('test2')")
>>> cursor.execute("SELECT LAST_INSERT_ID()")
>>> print cursor.fetchone()
Expected:
{'LAST_INSERT_ID()': 8L}
Actual:
None
