pysqlite

I'm currently persisting filenames in a sqlite database for my own purposes. Whenever I try to insert a file that has a special character (like é etc.), it throws the following error: pysqlite2.dbapi2.ProgrammingError: You must not use 8-bit bytestrings unless you use a text_factory that can interpret 8-bit bytestrings (like text_factory = str). It is highly recommended that you instead just switch your application to Unicode strings. When I do "switch my application over to Unicode strings" by wrapping the value sent to pysqlite with the unicode method like: unicode(filename) , it throws this

Why does from pysqlite2 import dbapi2 as sqlite cause ImportError: No module named pysqlite2 Isn't pysqlite2 already installed in Python 2.6.5? The module is called sqlite3 . pysqlite2 was the module's name before it became part of the Python standard library. You probably want to use this in your code: import sqlite3 And the standard documentation is here: http://docs.python.org/library/sqlite3.html edit: And just to cover all the bases: The sqlite3 module also has a dbapi2 sub-member, but you don't need to use it directly. The sqlite3 module exposes all the dbapi2 members directly. 来源： https

I'm trying this code: import sqlite connection = sqlite.connect('cache.db') cur = connection.cursor() cur.execute('''create table item (id integer primary key, itemno text unique, scancode text, descr text, price real)''') connection.commit() cur.close() I'm catching this exception: Traceback (most recent call last): File "cache_storage.py", line 7, in <module> scancode text, descr text, price real)''') File "/usr/lib/python2.6/dist-packages/sqlite/main.py", line 237, in execute self.con._begin() File "/usr/lib/python2.6/dist-packages/sqlite/main.py", line 503, in _begin self.db.execute("BEGIN

In this post about SQLite , aaronasterling told me that cmd = "attach \"%s\" as toMerge" % "b.db" : is wrong cmd = 'attach "{0}" as toMerge'.format("b.db") : is correct cmd = "attach ? as toMerge"; cursor.execute(cmd, ('b.db', )) : is right thing But, I've thought the first and second are the same. What are the differences between those three? "attach \"%s\" as toMerge" % "b.db" You should use ' instead of " , so you don't have to escape. You used the old formatting strings that are deprecated. 'attach "{0}" as toMerge'.format("b.db") This uses the new format string feature from newer Python
