Oracle built-in data types-LONG and raw__oracle

--Start LONG

Long is actually a string, and Oracle does not recommend that we use long, which is designed for backward compatibility, using CLOB, NCLOB, or blobs if necessary.

LONG RAW

Long Raw is used to store binary data, and Oracle does not recommend that we use long raw, use a BLOB if necessary.
RAW

RAW is used to store binary data. With VARCHAR2, it is also a variable-length data type.

CREATE TABLE TEST
(
  COL RAW ()
);
INSERT into TEST VALUES (' 11001011 ');
SELECT * from TEST;
