Semi-structured and structured data functions (Cast)

Casts a VARIANT value to a TIME value. This function does not convert values of other data types, including timestamps, to TIME values.

AS_TIME( <variant_expr> )

variant_expr

An expression that evaluates to a value of type VARIANT.

The function returns a value of type TIME or NULL:

• If the type of the value in the variant_expr argument is TIME, the function returns a value of type TIME.

• If the type of the value in the variant_expr argument doesn’t match the type of the output value, the function returns NULL.

• If the variant_expr argument is NULL, the function returns NULL.

Create a table and load data into it:

CREATE OR REPLACE TABLE as_time_example (time1 VARIANT);

INSERT INTO as_time_example (time1)
  SELECT TO_VARIANT(TO_TIME('12:34:56'));

Copy

Use the AS_TIME function in a query to cast a VARIANT value to a TIME value:

SELECT AS_TIME(time1) AS time_value
  FROM as_time_example;

Copy
