CREATE TABLE SAMPLE_TABLE
(
    VARCHAR_TYPE VARCHAR,
    CHAR_TYPE CHAR(11),
    INTEGER_TYPE INTEGER,
    DATE_TYPE DATE,
    TIMESTAMP_TYPE TIMESTAMP,
    TIME_TYPE TIME,
    PERIOD_TYPE PERIOD(DATE)
);

REPLACE VIEW SAMPLE_VIEW 
AS
SELECT
CAST(DATE_TYPE AS SMALLINT),
CAST(DATE_TYPE AS DECIMAL),

CAST(DATE_TYPE AS FLOAT),
CAST(DATE_TYPE AS INTEGER)
FROM SAMPLE_TABLE;

Output:

SELECT
mod(PUBLIC.DATE_TO_INT_UDF(date '2015-11-26'), 5890),
sin(PUBLIC.DATE_TO_INT_UDF(CURRENT_DATE()));

CREATE TABLE PUBLIC.SAMPLE_TABLE
