Turns a subquery into a table. The function implements views (see [CREATE VIEW](https://clickhouse.com/docs/en/sql-reference/statements/create/view/#create-view)). The resulting table does not store data, but only stores the specified `SELECT` query. When reading from the table, ClickHouse executes the query and deletes all unnecessary columns from the result.
**Syntax**
``` sql
view(subquery)
```
**Arguments**
- `subquery` — `SELECT` query.
**Returned value**
- A table.
**Example**
Input table:
``` text
┌─id─┬─name─────┬─days─┐
│ 1 │ January │ 31 │
│ 2 │ February │ 29 │
│ 3 │ March │ 31 │
│ 4 │ April │ 30 │
└────┴──────────┴──────┘
```
Query:
``` sql
SELECT * FROM view(SELECT name FROM months);
```
Result:
``` text
┌─name─────┐
│ January │
│ February │
│ March │
│ April │
└──────────┘
```
You can use the `view` function as a parameter of the [remote](https://clickhouse.com/docs/en/sql-reference/table-functions/remote/#remote-remotesecure) and [cluster](https://clickhouse.com/docs/en/sql-reference/table-functions/cluster/#cluster-clusterallreplicas) table functions:
``` sql
SELECT * FROM remote(`127.0.0.1`, view(SELECT a, b, c FROM table_name));
```
``` sql
SELECT * FROM cluster(`cluster_name`, view(SELECT a, b, c FROM table_name));
```
