A SQL BLOB is a built-in type that stores a Binary Large Object as a column value in a row of a database table. The driver implements BLOB using a SQL locator(BLOB) , which means that a Blob object contains a logical pointer to the SQL BLOB data rather than the data itself.
A Blob object is valid for the duration of the transaction in which is was created.

Methods in the interfaces XResultSet , and XPreparedStatement , such as getBlob and setBlob allow a programmer to access the SQL BLOB .
The Blob interface provides methods for getting the length of a SQL BLOB (Binary Large Object) value, for materializing a BLOB value on the client and for determining the position of a pattern of bytes within a BLOB value.
