### Description
The `INSERT INTO` statement inserts new rows into a table. The inserted rows can be specified by value expressions or result from a query.
### Syntax
```sql
INSERT INTO [ TABLE ] table_identifier [ partition_spec ]
{ VALUES ( { value | NULL } [ , ... ] ) [ , ( ... ) ] | query }
```
### Parameters
* **table_identifier**
Specifies a table name, which may be optionally qualified with a database name.
**Syntax:** `[ database_name. ] table_name`
* **partition_spec**
An optional parameter that specifies a comma separated list of key and value pairs
for partitions.
**Syntax:** `PARTITION ( partition_col_name = partition_col_val [ , ... ] )`
* **VALUES ( { value `|` NULL } [ , ... ] ) [ , ( ... ) ]**
Specifies the values to be inserted. Either an explicitly specified value or a NULL can be inserted.
A comma must be used to separate each value in the clause. More than one set of values can be specified to insert multiple rows.
* **query**
A query that produces the rows to be inserted. It can be in one of following formats:
* a `SELECT` statement
* a `TABLE` statement
* a `FROM` statement
