MySQL BLOB (Binary Large Object)

JDBC for MySQL - Herong's Tutorial Examples

∟MySQL BLOB (Binary Large Object) - BLOB

This chapter provides tutorial notes on BLOB (Binary Large Object) data types, BLOB, with MySQL JDBC Driver. Topics include creating tables to store BLOB values in MySQL 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.

These sections are omitted from this Web preview version. To view the full content, see information on how to obtain the full version this book.

Overview of BLOB (Binary Large Object)

Create Tables with CLOB Columns

Inserting BLOB Values with SQL INSERT Statements

Inserting BLOB Values with setBytes() Method

Inserting BLOB Values with setBinaryStream() Method

Closing InputStream Too Early on setBinaryStream()

Retrieving BLOB Values with getBytes() Method

Retrieving BLOB Values with getBinaryStream() Method

Retrieving BLOB Values with getBlob() Method

Inserting BLOB Values with setBlob() Method

Takeaways:

MySQL Server support BLOB data type with column type of LONGBLOB that hold a binary value of up to 4,294,967,295 or 4GB (2**32 - 1) bytes.
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.
Binary data can be retrieved from a BLOB column using getBytes(), getBinaryStream(), and getBlob() methods on the ResultSet object.
