How did the string u"1,2,3,4" get into the database in the first place?
The sqlite3 module offers a mechanism to convert data from and to Python
(semi-)transparently:
import sqlite3
import json
sqlite3.register_adapter(list, json.dumps)
sqlite3.register_converter("list", json.loads)
db = sqlite3.connect(":memory:", detect_types=sqlite3.PARSE_DECLTYPES)
cursor = db.cursor()
cursor.execute("create table data (value list)")
cursor.execute("insert into data values (?)", ([11,22,33],))
for row in cursor.execute("select value from data"):
print row
