1553615704,I_kwDOBm6k_c5cmktY,2001,Datasette is not compatible with SQLite's strict quoting compilation option,406380,open,0,,,4,2023-01-23T19:10:07Z,2023-01-25T04:59:58Z,,NONE,,"I have linked Python3.11 on macOS against recent SQLite that was compiled using `-DSQLITE_DQS=0`. This option disables interpretation of double-quoted identifiers as string literals, described in the SQLite docs as a ""MySQL 3.x misfeature"". See https://www.sqlite.org/quirks.html#dblquote for background.

Datasette uses the double-quote syntax in a number of key places, and is thus completely broken in this environment.

My experience was to `pip install datasette`, then run `datasette serve -I my-data.db`. When I visit `http://127.0.0.1:8001` I get a 500 response.

The error: `sqlite3.OperationalError: no such column: geometry_columns`

The responsible SQL: `'select 1 from sqlite_master where tbl_name = ""geometry_columns""'`

I then installed datasette from GitHub master in development mode and changed the offending SQL to use correct quotes: `""select 1 from sqlite_master where tbl_name = 'geometry_columns'""`.

With this change, I get a little further, but have the same problem with the first table name in my database (in my case, ""Meta""):
```

```

I will try to continue playing with this, but I also hope that the datasette developers will enable this mode in a test environment as I am unlikely to be able to exercise all of the SQL in the codebase, or make a pull request very soon.

Note that the DQS setting compile-time option can be overridden at runtime with calls to the C API:
```
sqlite3_db_config(db, SQLITE_DBCONFIG_DQS_DDL, 0, (void*)0);
sqlite3_db_config(db, SQLITE_DBCONFIG_DQS_DML, 0, (void*)0);
```

As far as I can tell, `sqlite3_db_config` is not exposed in Python, but perhaps we could figure out how to invoke it using `ctypes`.
