∟Oracle BLOB (Binary Large Object) - BLOB

This chapter provides tutorial notes on BLOB (Binary Large Object) data types, BLOB, with Oracle JDBC Driver. Topics include creating tables to store BLOB values in Oracle server; inserting BLOB values with direct SQL INSERT statements, or PreparedStatement with setBytes(), setBinaryStream() or setBlob() methods; retrieving BLOB values from ResultSet with getBytes(), getBinaryStream() or getBlob() method.

Takeaways:

Oracle support BLOB data type with column type of BLOB.
Binary data can be directly inserted into a BLOB column using the INSERT statement.
Binary data can also be indirectly inserted into a BLOB column using the PreparedStatement object with setBytes(), setBinaryStream(), and setBlob() methods.
