Hi Guys, i don't know what i did wrong; i try to build some header functions for my python application so i don't call every statement in a function; CREATE TABLE IF NOT EXISTS CFG_STATS_FACEIT( CurrentElo TEXT, Rank TEXT, EloToday TEXT, WinStreak TEXT, TotalMatches TEXT, MatchesWon TEXT ) sqlite3db.TExecSqlInsert(DBNAME, """ INSERT INTO CFG_STATS_FACEIT VALUES (?, ?, ?, ?, ?, ?)""", FACEIT_List) def TExecSqlInsert(database_name: str, statement: str, bind: list = None): try: conn = sqlite3.connect(database_name) c = conn.cursor() if bind: if bind.__class__.__name__ in ('list', 'tuple'): c.execute(statement, bind) else: c.execute(statement, [bind]) else: c.execute(statement) conn.commit() conn.close() except sqlite3.Error as err: print(err) Values: list (True, True, True, True, True, True) does someone see any errors ? Cheers and thx

TExecSqlInsert is a function, not a method of a class. However if one removes the useless instance variable it works as coded. What exactly is the problem?

my problem is i insert the vlaues 'True' into a Text Column. and SQLITE3 is converting this to a 1. I was 100% sure the "boolean" function isn't avaible in SQLITE3.

True and false are keywords in sqlite:
$ sqlite3 ... sqlite> select true; 1 sqlite> select false; 0

This is possibly a redundant remark, but it's worth keeping in mind the difference between the keyword
true and the string
'true'. The latter is not converted to 1.

True is 1, and False is 0. The sqlite3 Python wrapper is translating the Python Boolean values (True, False) to something understood by sqlite3 -- the integers 1 and 0 respectively.
Since you are inserting those integer values into a column with TEXT affinity, sqlite3 is converting the integer 1 and 0 to the strings '1' and '0' respectively.
If you insert the value 'True' then you will get that value, however True is not 'True'. True is a python boolean type (1, since that is not 0) and 'True' is a text string (and 'True' is actually False in sqlite3, because when the string 'True" is converted to a number, that number is 0, which is False).
