    columnB VARCHAR(15),
    columnC INT,

    columnE DATE
)
STORED AS ORC;

Table Creation with Partitioning:

CREATE TABLE test_partition (
    columnA STRING,
    columnB VARCHAR(15),
    columnC INT,
    columnD TIMESTAMP,
    columnE DATE
)
PARTITIONED BY (columnF INT)
STORED AS ORC;

Inline Table Creation:

CREATE TABLE test_inline STORED AS ORC AS
SELECT *
FROM test;

Temporary Table Creation:

CREATE TEMPORARY TABLE temp (
    columnA STRING,
    columnB VARCHAR(15),
    columnC INT,
    columnD TIMESTAMP,
    columnE DATE
)
STORED AS ORC;
