SQLite3 problems

[Suwayya]

db = sqlite3.connect('mydb.db')
f1l = []
f1l = db.execute("SELECT f1 FROM t1").fetchall()
for i in range(0,len(f1l)):
    xmlfile = matchf1(f1l[i])
    print xmlfile
    postcount = 0
    for node in xmlfile.getElementsByTagName("t1"):
        c1 = node.getAttribute("c1")
    if c1 != 0:
        for node2 in xmlfile.getElementsByTagName("t2"):
            y = node2.getAttribute("t")
            x = f1l[i]
            db.execute("UPDATE t1 SET f2='%s' WHERE f1='%s'"%(y,x))
            print y + " added to" + f1l[i]
db.commit()
db.close()

Ends up with:
Traceback (most recent call last):
File "D:\sumthin.py" , line 28, in <module>
db.execute("UPD ATE t1 SET f2='%s' WHERE f1='%s'"%(y,x))
OperationalErro r: near "005": syntax error

The data base got the table "t1" and the fields "f1" and "f2".
In all rows "f1" is filled and "f2" is "none".

Any suggestions?
