New in SQLite 3.37.0, released a few days ago: https://www.sqlite.org/stricttables.html

I keep making this mistake: bash sqlite-utils add-column content.db assets _since int ``` Usage: sqlite-utils add-column [OPTIONS] PATH TABLE COL_NAME [[integer|float|b lob|text|INTEGER|FLOAT|BLOB|TEXT]] Try 'sqlite-utils add-column -h' for help.

Error: Invalid value for '[[integer|float|blob|text|INTEGER|FLOAT|BLOB|TEXT]]': 'int' is not one of 'integer', 'float', 'blob', 'text', 'INTEGER', 'FLOAT', 'BLOB', 'TEXT'. ```

https://github.com/simonw/sqlite-utils-plugins should be in the official documentation.

I can use the same pattern as https://llm.datasette.io/en/stable/plugins/directory.html

As seen in https://til.simonwillison.net/sqlite/import-csv - .mode csv and then .import school.csv schools is hugely faster than importing via sqlite-utils insert and doing the work in Python - but it can only be implemented by shelling out to the sqlite3 CLI tool, it's not functionality that is exposed to the Python sqlite3 module.

An option to use this would be useful - maybe something like this:

sqlite-utils insert blah.db blah blah.csv --fast

Given this schema: sql CREATE TABLE departments ( campus_name TEXT NOT NULL, dept_code TEXT NOT NULL, dept_name TEXT, PRIMARY KEY (campus_name, dept_code) ); CREATE TABLE courses ( course_code TEXT PRIMARY KEY, course_name TEXT, campus_name TEXT NOT NULL, dept_code TEXT NOT NULL, FOREIGN KEY (campus_name, dept_code) REFERENCES departments(campus_name, dept_code) ); The output of db["courses"].foreign_keys right now is: [ForeignKey(table='courses', column='campus_name', other_table='departments', other_column='campus_name'), ForeignKey(table='courses', column='dept_code', other_table='departments', other_column='dept_code')] Which suggests two normal foreign keys, not one compound foreign key.

I just spotted a bug when using https://datasette.io/plugins/datasette-configure-fts and https://datasette.io/plugins/datasette-edit-schema at the same time.

Steps to reproduce:

• Configure FTS for a table, then run a test search
• Edit the schema for that table and change the order of columns
• Run the test search again

I got the wrong search results, which I think is because the _fts table pointed to the first table by rowid but those rowid values were entirely rewritten as a consequence of running table.transform() on the table.

Reconfiguring FTS on the table fixed the problem.

I think table.transform() should be able to preserve rowid values.

Refs: - #592

• [x] Tests against weird shaped tables

I need to test that this works against:

• rowid tables
• Tables that have a column called rowid even though they are not rowid tables

:books: Documentation preview :books:: https://sqlite-utils--593.org.readthedocs.build/en/593/

Currently the constructor accepts memory=True or memory_name=... and uses those to create a connection, but does not record what those values were:

https://github.com/simonw/sqlite-utils/blob/1260bdc7bfe31c36c272572c6389125f8de6ef71/sqlite_utils/db.py#L307-L349

This makes it hard to tell if a database object is to an in-memory or a file-based database, which is sometimes useful to know.

I used a custom SQL function in a migration script and then realized that it should be de-registered before the end of the script to avoid leaking into the calling code.

This came up working on this feature: - https://github.com/simonw/llm/pull/186

I have a table with this schema: sql CREATE TABLE [collections] ( [id] INTEGER PRIMARY KEY, [name] TEXT, [model] TEXT ); CREATE UNIQUE INDEX [idx_collections_name] ON [collections] ([name]); So the primary key is an integer (because it's going to have a huge number of rows foreign key related to it, and I don't want to store a larger text value thousands of times), but there is a unique constraint on the name - that would be the primary key column if not for all of those foreign keys.

Problem is, fetching the collection by name is actually pretty inconvenient.

Fetch by numeric ID:

python try: table["collections"].get(1) except NotFoundError: # It doesn't exist Fetching by name: python def get_collection(db, collection): rows = db["collections"].rows_where("name = ?", [collection]) try: return next(rows) except StopIteration: raise NotFoundError("Collection not found: {}".format(collection)) It would be neat if, for columns where we know that we should always get 0 or one result, we could do this instead: python try: collection = table["collections"].get(name="entries") except NotFoundError: # It doesn't exist The existing .get() method doesn't have any non-positional arguments, so using **kwargs like that should work:

https://github.com/simonw/sqlite-utils/blob/1260bdc7bfe31c36c272572c6389125f8de6ef71/sqlite_utils/db.py#L1495

Extremely detailed story of how I got to this point:

• https://github.com/simonw/llm/issues/162

Steps to reproduce (only if that pragma is on though): bash python -c ' import sqlite_utils db = sqlite_utils.Database(memory=True) db.execute(""" CREATE TABLE "logs" ( [id] INTEGER PRIMARY KEY, [model] TEXT, [prompt] TEXT, [system] TEXT, [prompt_json] TEXT, [options_json] TEXT, [response] TEXT, [response_json] TEXT, [reply_to_id] INTEGER, [chat_id] INTEGER REFERENCES [log]([id]), [duration_ms] INTEGER, [datetime_utc] TEXT ); """) db["logs"].add_foreign_key("reply_to_id", "logs", "id") ' This succeeds in some environments, fails in others.

https://github.com/simonw/sqlite-utils/blob/13ebcc575d2547c45e8d31288b71a3242c16b886/sqlite_utils/db.py#L1165-L1174

This is the only place in the code that attempts to modify sqlite_master directly, which fails on some Python installations.

Could this use the .transform() trick instead?

Or automatically switch to that trick if it hits an error?

I got this error trying to drop a column from a table that was part of a SQL view:

error in view plugins: no such table: main.pypi_releases

Upon further investigation I found that this pattern seemed to fix it: python def transform_the_table(conn): # Run this in a transaction: with conn: # We have to read all the views first, because we need to drop and recreate them db = sqlite_utils.Database(conn) views = {v.name: v.schema for v in db.views if table.lower() in v.schema.lower()} for view in views.keys(): db[view].drop() db[table].transform( types=types, rename=rename, drop=drop, column_order=[p[0] for p in order_pairs], ) # Now recreate the views for name, schema in views.items(): db.create_view(name, schema) So grab a copy of any view that might reference this table, start a transaction, drop those views, run the transform, recreate the views again.

I wonder if this should become an option in sqlite-utils? Maybe a recreate_views=True argument for table.tranform(...)? Should it be opt-in or opt-out?

What would it take to add a format hook? I'm still thinking about my GIS workflow, and being able to do sqlite-utils query ... --geojson would be nice. It's the one place my Datasette workflow is messy, having to do datasette . --get /path/to/query.geojson --setting max_rows_returned 10000 --load-extension spatialite. I know the current pattern is --csv, but maybe --format geojson is more future-proof.

While using sqlite-utils convert I realized it would be handy if you could pass --pdb to have it open the debugger at the first instance of a failed conversion.

Currently the changelog starts at 0.4:

https://sqlite-utils.datasette.io/en/3.34/changelog.html#id115

I want the other releases - according to https://pypi.org/project/sqlite-utils/#history there are three missing:

Plugins affecting the CLI by default makes sense to me.

I'm less confident about them always affecting users of the Python API.

I'm going to have them apply by default, but I'm going to add a mechanism to opt-out on an individual database basis. Basically this:

```python from sqlite_utils import Database db = Database(memory=True, execute_plugins=False)

Anything using db from here on will not execute plugins

Also need a design for an option for the .transform() method to indicate that the new table should be created with a new name without dropping the old one.

I think keep_table="name_of_table" is good for this.

Originally posted by @simonw in https://github.com/simonw/sqlite-utils/issues/565#issuecomment-1646657324

Spotted this in the GitHub Actions logs:

... and it turns out running .transform() with no arguments still fixes the format of the schema!

```pycon

db["log"].add_column("foo", str)

For every command/API method there should be a link to the equivalent in the other form factor.

Maybe also link to the API and CLI reference pages too.

I find myself wanting two new features in sqlite-utils: - The ability to have the new transformed table set to a specific name, while keeping the old table around - The ability to rename a table (sqlite-utils doesn't have a table rename function at all right now)

Originally posted by @simonw in https://github.com/simonw/llm/issues/65#issuecomment-1618375042

Found myself using this pattern to quickly prototype a schema:

```python import sqlite_utils db = sqlite_utils.Database(memory=True)

print(db["answers_chunks"].create({ "id": int, "content": str, "embedding_type_id": int, "embedding": bytes, "embedding_content_md5": str, "source": str, }, pk="id", transform=True).schema) ```

Using replace=True to drop and then recreate the table would be neat here, and would be consistent with other places that use replace=True.

I'm going to start by adding the register_command hook using the exact same pattern as Datasette and LLM.

As seen in LLM.

Needed while working on: - #567

CSV files with empty cells in (which come through as the empty string) are common and a bit gross.

Having an option that means "and if it's an empty string store null instead) would be cool.

I brainstormed name options here https://chat.openai.com/share/c947b738-ee7d-419c-af90-bc84e90987da

Aside: this makes me think it might be cool if sqlite-utils had a way of working with dataclasses rather than just dicts, and knew how to create a SQLite table to match a dataclass and maybe how to code-generate dataclasses for a specific table schema (dynamically or even using code-generation that can be written to disk, for better editor integrations).

Need to add this to the installation docs here: https://sqlite-utils.datasette.io/en/stable/installation.html - along with the pattern for adding that to .zshrc or whatever.

The 158: None there is duplicate information considering we already know there are 158/158 null rows.

In playing with the new SpatiaLite helpers from #385 I noticed that actually populating geometry columns is still a little bit tricky. Here's what I ended up doing:

```python import httpx, sqlite_utils db = sqlite_utils.Database("/tmp/spatial.db") attractions = httpx.get("https://latest.datasette.io/fixtures/roadside_attractions.json?_shape=array").json() db["attractions"].insert_all(attractions, pk="pk")

Schema of that table is now:

CREATE TABLE [attractions] (

[pk] INTEGER PRIMARY KEY,

[name] TEXT,

[address] TEXT,

[latitude] FLOAT,

[longitude] FLOAT

)

db.init_spatialite() db["attractions"].add_geometry_column("point", "POINT")

db.execute(""" update attractions set point = GeomFromText( 'POINT(' || longitude || ' ' || latitude || ')', 4326 ) """) `` That last line took some figuring out - especially the need for the SRID of4326`, without which I got this error:

IntegrityError: attractions.point violates Geometry constraint [geom-type or SRID not allowed]

It would be good to both document this in more detail, but ideally also to come up with a more obvious pattern for inserting common types of spatial data.

It looks like there's a default limit of 999 variables - we need to be smart about that, maybe dynamically lower the batch size based on the number of columns.

In building this Datasette feature on top of sqlite-utils I thought it might be useful to expose the number of rows that had been affected by a bulk insert or update - the cursor.rowcount:

• https://github.com/simonw/datasette/issues/1866

This isn't currently exposed by sqlite-utils.

Added in: - #483

I don't know how to fix this in Sphinx: I'm getting this: https://sqlite-utils.datasette.io/en/latest/cli.html#cli-install

The insert –convert and query –functions options

But I want it to display insert --convert and not insert –convert there.

Here's the code: https://github.com/simonw/sqlite-utils/blob/85247038f70d7eb2f3e272cfeaa4c44459cafba8/docs/cli.rst#L2125

I ended up needing to use db.conn.close() to fix this issue: - #503

I think .close() should be a method on Database itself.

This can be a documented wrapper around with db.conn:.

I'm using just a lot know, based on this file - I should add that to https://sqlite-utils.datasette.io/en/latest/contributing.html

https://github.com/simonw/sqlite-utils/blob/afbd2b2cba45cccb305c3d4638d18db4dd3d4bbd/Justfile#L1-L24

With the addition of --functions in: - #471

In addition to the existing convert command, there are now very good reasons to want to install additional packages into the same virtual environment as sqlite-utils itself, to allow them to be used with those features.

This isn't easy if you installed the tool with pipx or brew install sqlite-utils.

Datasette solved this problem with the datasette install command:

• https://github.com/simonw/datasette/issues/925

sqlite-utils could benefit from the same idea.

Got this idea from this example in https://jeqo.github.io/notes/2022-09-24-ingest-logs-sqlite/

bash sqlite-utils insert /tmp/kafka-logs.db logs server.log.2022-09-24-21 --text --convert " import re r = re.compile(r'^\[(?P<datetime>\d{4}-\d{2}-\d{2} \d{2}:\d{2}:\d{2},\d{3})\] (?P<level>\w+) (?P<log>(.+(\n(?\!\[).+|)+))', re.MULTILINE) def convert(text): rows = [m.groupdict() for m in r.finditer(text)] for row in rows: row.update({'server': 'localhost'}) row.update({'component': 'broker'}) return rows " And the accompanying note:

The row.update allows to label rows as I’m planning to ingest logs from different hosts and potentially different components.

This made me think: it might be neat if you could inject additional variable values into that script with extra command-line options, to make this kind of reuse easier. Something like this:

bash sqlite-utils insert /tmp/kafka-logs.db logs server.log.2022-09-24-21 --text --convert " import re r = re.compile(r'^\[(?P<datetime>\d{4}-\d{2}-\d{2} \d{2}:\d{2}:\d{2},\d{3})\] (?P<level>\w+) (?P<log>(.+(\n(?\!\[).+|)+))', re.MULTILINE) def convert(text): rows = [m.groupdict() for m in r.finditer(text)] for row in rows: row.update({'server': server}) row.update({'component': component}) return rows " --var server "localhost" --var component "broker"

It's very common for JSON to look like this: json { "Version": "5.5.52.6", "List": [ { "Description": "Nonpartisan", "Id": 1, "ExternalId": "" }, { "Description": "Undeclared", "Id": 2, "ExternalId": "" } ] } This example taken from the records downloaded from https://www.elections.alaska.gov/election-results/e/

Right now you can't import this into sqlite-utils - you need to run it through jq .List first.

But since this is so common, it would be neat if sqlite-utils could have a rule of thumb that says "if it's an object, but it has a single key that is is a list of objects, use that instead".

--functions was added in: - #471

It would be useful if the r.jsonsplit() and similar recipes for sqlite-utils convert could be used in these blocks of code too: https://sqlite-utils.datasette.io/en/stable/cli.html#sqlite-utils-convert-recipes

It would be really cool if you could register additional custom SQL functions for use with the sqlite-utils query command - something like this:

``` sqlite-utils data.db 'update images set domain = extract_domain(url)' --functions ' from urllib.parse import urlparse

def extract_domain(url): return urlparse(url).netloc ' ``` Every function defined in that code block would be registered with the connection, unless the name began with an underscore.

Imagine a table (imported from a nested JSON file) where one of the columns contains values that look like this:

{"email": "anonymous@noreply.airtable.com", "id": "usrROSHARE0000000", "name": "Anonymous"}

The sqlite-utils extract command already uses single text values in a column to populate a new table. It would not be much of a stretch for it to be able to use JSON instead, including specifying which of those values should be used as the primary key in the new table.

Could offer syntactic sugar for:

sql create table foo as select * from bar

sqlite-utils create-table data.db foo --sql "select * from bar" https://sqlite-utils.datasette.io/en/stable/cli-reference.html#create-table

The sqlite-utils tables command currently lists all tables.

If you have a huge table in there then running it with --counts can get expensive, because of the huge table.

Would be useful if it could accept an optional list of tables that it should execute against, as an alternative to the default of all of them.

This should be a backwards compatible change. Current design is: https://sqlite-utils.datasette.io/en/stable/cli-reference.html#tables

``` Usage: sqlite-utils tables [OPTIONS] PATH

List the tables in the database

Example:

  sqlite-utils tables trees.db

```

Interesting challenge with default_value: I need to be able to tell if the default values passed to .create() differ from those in the database already.

Introspecting that is a bit tricky:

```pycon

import sqlite_utils db = sqlite_utils.Database(memory=True) db["blah"].create({"id": int, "name": str}, not_null=("name",), defaults={"name": "bob"}) <Table blah (id, name)> db["blah"].columns [Column(cid=0, name='id', type='INTEGER', notnull=0, default_value=None, is_pk=0), Column(cid=1, name='name', type='TEXT', notnull=1, default_value="'bob'", is_pk=0)] `` Note how a default value of the Python stringbobis represented in the results ofPRAGMA table_info()asdefault_value="'bob'"` - it's got single quotes added to it!

So comparing default values from introspecting the database needs me to first parse that syntax. This may require a new table introspection method.

For consistency with search: https://sqlite-utils.datasette.io/en/stable/cli-reference.html#search

-o, --order TEXT Order by ('column' or 'column desc')

I wanted to run sqlite-utils rows db.db mytable --order 'rowid desc' to see the most recently imported rows.

In this example:

```python @db.register_function def reverse_string(s): return "".join(reversed(list(s)))

print(db.execute('select reverse_string("hello")').fetchone()[0])

``` There's currently no way to over-ride the automatically selected name for the SQL function.

The GitHub JSON APIs have a really interesting convention with respect to related objects.

Consider https://api.github.com/repos/simonw/sqlite-utils/issues - here's a truncated subset: json { "id": 449818897, "node_id": "MDU6SXNzdWU0NDk4MTg4OTc=", "number": 24, "title": "Additional Column Constraints?", "user": { "login": "IgnoredAmbience", "id": 98555, "node_id": "MDQ6VXNlcjk4NTU1", "avatar_url": "https://avatars0.githubusercontent.com/u/98555?v=4", "gravatar_id": "" }, "labels": [ { "id": 993377884, "node_id": "MDU6TGFiZWw5OTMzNzc4ODQ=", "url": "https://api.github.com/repos/simonw/sqlite-utils/labels/enhancement", "name": "enhancement", "color": "a2eeef", "default": true } ], "state": "open" } The user column lists a complete user. The labels column has a list of labels.

Since both user and label have populated id field this is actually enough information for us to create records for them AND set up the corresponding foreign key (for user) and m2m relationships (for labels).

It would be really neat if sqlite-utils had some kind of mechanism for correctly processing these kind of patterns.

Thanks to jq there's not much need for extra customization of the shape here - if we support a narrowly defined structure users can use jq to reshape arbitrary JSON to match.
