Here is the list of Oracle In Built data types
Oracle Built-In Datatypes
A datatype associates a fixed set of properties with the values that can be used in a column of a table or in an argument of a procedure or function. These properties cause Oracle to treat values of one datatype differently from values of another datatype. For example, Oracle can add values of NUMBER datatype, but not values of RAW datatype.
Oracle supplies the following built-in datatypes:
Character datatypes
CHAR
NCHAR
VARCHAR2 and VARCHAR
NVARCHAR2
CLOB
NCLOB
LONG
NUMBER datatype
DATE datatype
Binary datatypes
BLOB
BFILE
RAW
LONG RAW
Another datatype, ROWID, is used for values in the ROWID pseudocolumn, which represents the unique address of each row in a table.
The RAW and LONG RAW datatypes are provided for backward compatibility with existing applications. For new applications, you should use the BLOB and BFILE datatypes for large amounts of binary data
