Question: drop table in python with sqlite3?

I want to drop a table from within Python. The command

cur.execute('drop table if exists tab1')

and

cur.executescript('drop table if exists tab1;')

both work fine if execute python script directly under Linux command window.

But why the first one doesn't work if call python script from some tinuous integration tools, such as, Hudson (http://hudson.dev.java.net/)
Why ?


My script for example: drop.py

import os, re
import sqlite3

conn = sqlite3.connect("./SQLiteDatabase.db3")
cursor = conn.cursor()

cursor.execute("drop view if exists table1")
cursor.executescript("drop view if exists table2;")
conn.close()
