What is session timezone in Oracle?

SESSIONTIMEZONE returns the time zone of the current session. The return type is a time zone offset (a character type in the format ‘[+|]TZH:TZM’ ) or a time zone region name, depending on how the user specified the session time zone value in the most recent ALTER SESSION statement.

What is TIMESTAMP with timezone?

The TIMESTAMP WITH TIME ZONE (or TIMESTAMPTZ) data type stores 8-byte date values that include timestamp and time zone information in UTC format. You cannot define a TIMESTAMPTZ column with a specific precision for fractional seconds other than 6. The timestamp is converted to UTC +1:00 (an 8-hour offset).

Can we store TIMESTAMP in date datatype in Oracle?

Oracle has expanded on the DATE datatype and has given us the TIMESTAMP datatype which stores all the information that the DATE datatype stores, but also includes fractional seconds. If you want to convert a DATE datatype to a TIMESTAMP datatype format, just use the CAST function.
