```js
|
|
const { data, error } = await supabase
|
|
.from('countries')
|
|
.select('name, id, main_exports')

.containedBy('main_exports', ['cars', 'food', 'machine'])
|
|
```
|

|
|
## Notes
|
|
|
|
- `.containedBy()` can work on array columns or range columns.
|
|
|
|
```js
|
|
.containedBy('arraycol',["a","b"]) // You can use a javascript array for an array column
|
|
.containedBy('arraycol','{"a","b"}') // You can use a string with Postgres array {} for array column.
|
|
.containedBy('rangecol','(1,2]') // Use Postgres range syntax for range column.
|
|
.containedBy('rangecol',`(${arr}]`) // You can insert an array into a string.
|
|
```
|
|
|
|
## Examples
|
|
|
|
### With `select()`
|
|
|
|
```js
|
|
const { data, error } = await supabase
|
|
.from('countries')
|
|
.select('name, id, main_exports')
|
|
.containedBy('main_exports', ['cars', 'food', 'machine'])
|
|
```
|
|
|
|
### With `update()`
|
|
|
|
```js
|
|
const { data, error } = await supabase
|
|
.from('countries')
|
|
.update({ name: 'Mordor' })
|
|
.containedBy('main_exports', ['orks', 'surveillance', 'evil'])
|
|
```
|
|
|
|
### With `delete()`
|
|
|
|
```js
|
|
const { data, error } = await supabase
|
|
.from('countries')
|
|
.delete()
|
|
.containedBy('main_exports', ['cars', 'food', 'machine'])
|
|
```
|
|
|
|
### With `rpc()`
|
|
|
|
```js
|
|
// Only valid if the Postgres function returns a table type.
|
|
const { data, error } = await supabase
|
|
.rpc('echo_all_countries')
|
|
.containedBy('main_exports', ['cars', 'food', 'machine'])
|
|
```
