MySQLdb executemany

I seem to have found a bug/limitation of executemany in MySQLdb.

I am inserting 3100 records into a database. It works fine and adds them
in about 1 second.

I went back to the program today and realised i'd missed a field so
added it to the insert statement. This seems to break it if I try to add
all the records in one go. Through trial and error I have realised the
limit is 2786 records in one go. Any more than that I get two different
errors on the executemany statement:

"MySQL server has gone away" - This occurs if I try to add all 3100
records in one go.

"Lost Connection to MySQL server during query" - This happens if I am
near the 2786 threshold.

Is there a known limit with this function???

Greetings, I am attempting to get MySQLdb 0.9.2 installed on Mac OS 10.2 with a Fink distribution of Python 2.2.2.

I have compiled MySQL 4.1 and installed into /usr/local/mysql, but since have moved to a Fink...

I have just started playing around with MySQLdb for a project I am planning. As a test I have written a script that executes 3000 insert statements on a table. The table contains 10 fields with a mix of text and numbers - its a product table for a website eg UPC, ProductName, Price etc. The problem I have is that it takes just over two minuted to execute the 3000 insert statements which seems really slow! I am running it on a machine...

The method cursor.executemany is there in order to avoid multiple calls to cursor.execute(). I have tried, with success, to do like every single example (that I have found on the www) on the subject shows, to use a insert statement on the form: statement = INSERT INTO table (colA,colB,colC) values (%s,%s,%s) and pass in a list containing tuples list =

- Are there any peculiarities with using curs.executemany(...) vs. multiple How many times are you calling execute vs a single executemany? The python call overhead will add up for thousands of calls. The relevant source code is here if you're interested: http://svn.python.org/projects/python/trunk/Modules/_sqlite/cursor.c
