Returns expr cast to a date using an optional formatting.

Syntax

to_date(expr [, fmt] )

  • expr: A STRING expression representing a date.
  • fmt: An optional format STRING expression.

Returns

A DATE.

Note

In Databricks Runtime, if spark.sql.ansi.enabled is false, the function returns NULL instead of an error for malformed dates.
