Apache Hive : HPL/SQL - INCLUDE Statement

INCLUDE statement allows you to include statements from another HPL/SQL script.

You can define user-defined functions and stored procedures in separate HPL/SQL scripts and then use INCLUDE statements to make them available in the current script.

Additionally you can put INCLUDE statements to .hplsqlrc configuration file, so these functions and procedures are always available to users similar to persistent objects in the database.

Syntax:

INLCUDE file_name; 

Notes:

• file_name is the path to the file (quoted or unquoted) or an expression

Example:

Create a separate file set_message.sql containing:

CREATE PROCEDURE set_message(IN name STRING, OUT result STRING)
BEGIN
 SET result = 'Hello, ' || name || '!';
END;

The call the procedure from another script as follows:

INCLUDE set_message.sql

DECLARE str STRING;
CALL set_message('world', str);
PRINT str;

Result:
--
Hello, world!

Compatibility: HPL/SQL extension
