to_unix_timestamp
function
Applies to: Databricks SQL Databricks Runtime
Returns the timestamp in expr
as a UNIX timestamp.
Arguments
expr
: A STRING expression representing a timestamp.fmt: An optional format STRING expression.
Returns
A BIGINT.
If fmt
is supplied, it must conform with Datetime patterns.
If fmt
is not supplied, the function is a synonym for cast(expr AS TIMESTAMP)
.
If fmt
is malformed or its application does not result in a well formed timestamp, the function raises an error.
Note
In Databricks Runtime, if spark.sql.ansi.enabled is false
, the function returns NULL
instead of an error for malformed timestamps.
