TO_TIMESTAMP

Converts the input expressions to the corresponding timestamp.

Syntax

TO_TIMESTAMP(numeric_expression double) → timestamp

  • numeric_expression: A Unix epoch timestamp.

SELECT TO_TIMESTAMP(52 * 365.25 * 86400)
-- 2022-01-01 00:00:00

TO_TIMESTAMP(string_expression varchar, format varchar [, replaceErrorWithNull int32]) → timestamp

  • string_expression: The string from which to extract the timestamp.
  • format: String to specify format of the timestamp.
  • replaceErrorWithNull (optional): If 0, the function will fail when given malformed input. If 1, the function will return NULL when given malformed input.

-- NULL
