Currently the only way to do that it is to call `.upsert({full record})` with the primary key field matching an existing record - but this does not support partial updates.
```python
db[""events""].update(3, {""name"": ""Renamed""})
```
This method only works on an existing table, so there's no need for a `pk=""id""` specifier - it can detect the primary key by looking at the table.

If the primary key is compound the first argument can be a tuple:
```python
db[""events_venues""].update((3, 2), {""custom_label"": ""Label""})
```
The method can be called without the second dictionary argument. Doing this selects the row specified by the primary key (throwing an error if it does not exist) and remembers it so that chained operations can be carried out - see proposal in https://github.com/simonw/sqlite-utils/issues/23#issuecomment-507055345

Still to do:

- [x] Unit tests
- [x] Switch to using `.get()`
- [x] Better exceptions, plus unit tests for what happens if pk does not exist
- [x] Documentation
- [x] Ensure compound primary keys work properly
- [x] `alter=True` support",140912432,pull,,,"{""url"": ""https://api.github.com/repos/simonw/sqlite-utils/issues/38/reactions"", ""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",0,
