Converts string_expr to a DATE data type.
TO_DATE does not convert data to any of the other datetime data types. Do not use the TO_DATE function with a DATE value for string_expr. The first two digits of the returned DATE value can differ from the original string_expr depending on format_arg or the default date format.
TO_DATE is an overloaded scalar function whose return value data type is DATE.
