# INSERT OVERWRITE DIRECTORY with Hive format

### Description

The INSERT OVERWRITE DIRECTORY with Hive format overwrites the existing data in the directory with the new values using Hive SerDe. Hive support must be enabled to use this command. The inserted rows can be specified by value expressions or result from a query.

### Syntax

INSERT OVERWRITE [ LOCAL ] DIRECTORY directory_path
[ ROW FORMAT row_format ] [ STORED AS file_format ]
{ VALUES ( { value | NULL } [ , ... ] ) [ , ( ... ) ] | query }


### Parameters

• directory_path

Specifies the destination directory. The LOCAL keyword is used to specify that the directory is on the local file system.

• row_format

Specifies the row format for this insert. Valid options are SERDE clause and DELIMITED clause. SERDE clause can be used to specify a custom SerDe for this insert. Alternatively, DELIMITED clause can be used to specify the native SerDe and state the delimiter, escape character, null character, and so on.

• file_format

Specifies the file format for this insert. Valid options are TEXTFILE, SEQUENCEFILE, RCFILE, ORC, PARQUET, and AVRO. You can also specify your own input and output format using INPUTFORMAT and OUTPUTFORMAT. ROW FORMAT SERDE can only be used with TEXTFILE, SEQUENCEFILE, or RCFILE, while ROW FORMAT DELIMITED can only be used with TEXTFILE.

• 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

### Examples

INSERT OVERWRITE LOCAL DIRECTORY '/tmp/destination'
STORED AS orc
SELECT * FROM test_table;

INSERT OVERWRITE LOCAL DIRECTORY '/tmp/destination'
