Apache Hive : HPL/SQL - INSERT DIRECTORY Statement

INSERT DIRECTORY statement allows you to write the query results to a local or HDFS-compatible file system.

Syntax:

INSERT OVERWRITE [LOCAL] DIRECTORY directory select_statement

Notes:

• directory specifies the target directory (path, variable or expression)
• select_statement specifies the query (you can also use dynamic SQL string)

Examples:

Export sales data:

insert overwrite directory '/data/sales_daily' select * from sales_daily;

Export sales data from the specified table and put to the directory for the current date:

declare tabname string = 'sales_daily';

insert overwrite directory '/data/sales_' || current_date 
  'select * from ' || tabname;

Compatibility: Hive
