Hi,
It doesn't seen to work with me (or I cannot see the error at my code... :-/)
import sqlite
c = sqlite.connect("/tmp/t")
cur = c.cursor()
cur.execute("CREATE TABLE TEST (id integer, name text)")
cur.execute("INSERT INTO TEST VALUES (?, ?)", (1, "wow"))
Traceback (most recent call last):
File "<stdin>", line 1, in ?
File "/usr/lib/python2.4/site-packages/sqlite/main.py", line 255, in execute
self.rs = self.con.db.execute(SQL % parms)
TypeError: not all arguments converted during string formatting
What am I doing wrong??
Cheeers!

Hello,
you should let Pysqlite handle quote escaping by itself, by using "?"
characters in your SQL queries :
>>> from pysqlite2 import dbapi2 as sqlite
>>> conn = sqlite.connect(':memory:')
>>> cursor = conn.cursor()
>>> cursor.execute("CREATE TABLE t (id INTEGER, value TEXT)")
<pysqlite2.dbapi2.Cursor object at 0xa7dc2ec0>
>>> cursor.execute("INSERT INTO t (id, value) VALUES (?, ?)",
... (1, "It's a test with simple (') quote"))
<pysqlite2.dbapi2.Cursor object at 0xa7dc2ec0>
>>> cursor.execute("SELECT * FROM t")
<pysqlite2.dbapi2.Cursor object at 0xa7dc2ec0>
>>> cursor.fetchall()
[(1, u"It's a test with simple (') quote")]
By the way, SQLite use double quote ('') to escape simple quote :
"A string constant is formed by enclosing the string in single quotes ('). A
single quote within the
string can be encoded by putting two single quotes in a row - as in Pascal.
C-style escapes using
the backslash character are not supported because they are not standard SQL."
