# Access SQLite Result Values By Name With Row Factory
|
|
|
|
The default shape of a result from executing a row-returning statement with
|
|
`sqlite3` is a tuple. Whose values can be accessed positionally.
|
|
|
|
```python
|
|
>>> res = conn.execute("select * from projects;")
|
|
>>> res.fetchone()
|
|
(1, 'py-vmt', '2026-07-25 14:53:44', '2026-07-25 14:53:44')
|
|
```
|
|
|
|
If I want something a bit nicer, I can enable [_Row Factory_
|
|
results](https://docs.python.org/3/library/sqlite3.html#how-to-create-and-use-row-factories)
|
|
for my connection. The values on a _row_ can be accessed by name as well as
|
|
positionally.
|
|
|
|
```python
|
|
>>> conn.row_factory = sqlite3.Row
|
|
>>> res = conn.execute("select * from projects;")
|
|
>>> res.fetchone()
|
|
<sqlite3.Row object at 0x1019e3c40>
|
|
>>> r1 = _
|
|
>>> r1
|
|
<sqlite3.Row object at 0x1019e3c40>
|
|
>>> r1["name"]
|
|
'py-vmt'
|
|
>>> r1["id"]
|
|
1
|
|
>>> r1[1]
|
|
'py-vmt'
|
|
```
|
|
|
|
[I used Row Factory on a project
|
|
recently](https://github.com/jbranchaud/py-vmt/pull/9/changes) and I think it
|
|
made for an improvement in the readability of the code.
