Both of these issues are discussed in #1099. This PR only fixes the second one, because it's not clear what the right UX is for the first issue. ![Screenshot 2023-01-24 at 19-47-40 nlrb bargaining_unit](https://user-images.githubusercontent.com/536941/214454749-d53deead-4151-4329-a5d4-8a7a454de7d3.png) Some things that might not be desirable about this approach. 1. it changes the external API, by changing `column` => `columns` and `other_column` => `other_columns` (see inline comment for more discussion. 2. There are various places where the plural foreign keys have to be checked for length and discarded or transformed to singular.

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""): ``` OperationalError: no such column: Meta Traceback (most recent call last): File ""/Users/gwk/external/datasette/datasette/app.py"", line 1522, in route_path response = await view(request, send) ^^^^^^^^^^^^^^^^^^^^^^^^^ File ""/Users/gwk/external/datasette/datasette/views/base.py"", line 151, in view return await self.dispatch_request(request) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File ""/Users/gwk/external/datasette/datasette/views/base.py"", line 105, in dispatch_request response = await handler(request) ^^^^^^^^^^^^^^^^^^^^^^ File ""/Users/gwk/external/datasette/datasette/views/index.py"", line 70, in get ""fts_table"": await db.fts_table(table), ^^^^^^^^^^^^^^^^^^^^^^^^^ File ""/Users/gwk/external/datasette/datasette/database.py"", line 363, in fts_table return await self.execute_fn(lambda conn: detect_fts(conn, table)) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File ""/Users/gwk/external/datasette/datasette/database.py"", line 213, in execute_fn return await asyncio.get_event_loop().run_in_executor( ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File ""/usr/local/py/Python.framework/Versions/3.11/lib/python3.11/concurrent/futures/thread.py"", line 58, in run result = self.fn(*self.args, **self.kwargs) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File ""/Users/gwk/external/datasette/datasette/database.py"", line 211, in in_thread return fn(conn) ^^^^^^^^ File ""/Users/gwk/external/datasette/datasette/database.py"", line 363, in return await self.execute_fn(lambda conn: detect_fts(conn, table)) ^^^^^^^^^^^^^^^^^^^^^^^ File ""/Users/gwk/external/datasette/datasette/utils/__init__.py"", line 588, in detect_fts rows = conn.execute(detect_fts_sql(table)).fetchall() ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ sqlite3.OperationalError: no such column: Meta INFO: 127.0.0.1:50258 - ""GET / HTTP/1.1"" 500 Internal Server Error ``` 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`.
