Apache Hive : HPL/SQL - CREATE VOLATILE TABLE Statement
CREATE VOLATILE TABLE statement allows you to create a temporary table for the current session.
Syntax:
CREATE [SET | MULTISET] VOLATILE TABLE table_name
(
column_name data_type [NULL | NOT NULL]
[, ...]
)
[ ON COMMIT DELETE ROWS | ON COMMIT PRESERVE ROWS]
Notes:
- The volatile table is automatically dropped at the end of session.
For more details how temporary table support is implemented in HPL/SQL, see Native and Managed Temporary Tables.
Example:
Create a managed temporary table and use it in other SQL statements:
SET hplsql.temp.tables = managed;
CREATE VOLATILE TABLE temp1
(
c1 INT,
c2 STRING
);
INSERT INTO temp1 SELECT 1, 'A' FROM dual;
SELECT * FROM temp1;
