Create Tables with CLOB Columns

This section describes how to create tables with BLOB (LONGBLOB) columns in Oracle server.

Oracle support BLOB with the BLOB data type:

In order to test BLOB columns in Oracle server, I used the Oracle command line interface to create a test table with one BLOB column:

herong> sqlplus
Enter user-name: Herong/TopSecret

SQL> -- Create the test table with a BLOB column
  2 CREATE TABLE Image (ID INTEGER PRIMARY KEY,
  3    Subject VARCHAR(256),
  4    Body BLOB);

Table created.
