## Notes

- By default, every time you run `insert()`, the client library will make a `select` to return the full record.
  This is convenient, but it can also cause problems if your Policies are not configured to allow the `select` operation.
  If you are using Row Level Security and you are encountering problems, try setting the `returning` param to `minimal`.

## Examples

### Create a record

```js
const { data, error } = await supabase
  .from('cities')
  .insert([{ name: 'The Shire', country_id: 554 }])
```

### Bulk create

When running a bulk create, the operation is handled in a single transaction. If any of the inserts fail, all other operations are
rolled back.

```js
const { data, error } = await supabase.from('cities').insert([
  { name: 'The Shire', country_id: 554 },
  { name: 'Rohan', country_id: 555 },
])
```

### Upsert

For upsert, if set to true, primary key columns would need to be included
in the data parameter in order for an update to properly happen. Also, primary keys
used must be natural, not surrogate. There are however,
[workarounds](https://github.com/PostgREST/postgrest/issues/1118)
for surrogate primary keys.

```js
const { data, error } = await supabase.from('cities').insert(
  [
    { name: 'The Shire', country_id: 554 },
    { name: 'Rohan', country_id: 555 },
    { name: 'City by the Bay', country_id: 840 },
  ],
  { upsert: true }
)
```
