to_timestamp function (Databricks SQL)

Returns expr cast to a timestamp using an optional formatting.

Syntax 

to_timestamp(expr [, fmt] )

Arguments

  • expr: A STRING expression representing a timestamp.

  • fmt: An optional format STRING expression.

Returns

A TIMESTAMP.

If fmt is supplied, it must conform with Datetime patterns (Databricks SQL).

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.
