Sun provides a document that explains how to use binary large objects (blobs) in JDBC http://java.sun.com/j2se/1.4.1/docs/guide/jdbc/blob.html If you plan to use Oracle's JDBC driver, you will discover that Oracle provides a proprietary API for working with the Oracle BLOB column type. Oracle provides a document that explains some of the details "JDBC Developer's Guide and Reference Release 2 (9.2)" In chapter ... |

Hello everybody, I'm facing a problem with JDBC and Oracle when trying to insert a file into a blob in the database. Here's how i tried. I create a row in the database using the empty_blob() function to initialize the blob column. I then execute a select for update on that record ... this way Ilock the record and can in ... |
|
Rakkesh, The reasons for that is because you are doing multiple things in the same transaction. The row needs to be locked to make sure the data you are retieving is consistent with the data you are adding. Otherwise someone could change things in the middle and leave your data in an inconsistent state. If you were just inserting the BLOB, ... |
Hello, I am trying to store a byte array in an BLOB column. I set it with PreparedStatement.setBytes() and retrieve with ResultSet.getBytes(), and what I put in look nothing like what comes out, even using a simple {0,1,2,3} array for testing. I wrote similar code a few months ago to store serialized Java objects in a MySQL database, and it worked ... |

Hi AkhilGupta Gupta, My first reaction was to say "wrap it in something that does" but, on reflection, that may be a little naive. I've not checked a spec or anything but I imagine it may be necessary for all members to be serializable, so that wouldn't help. The other alternative is to define a SerializableMessage class and copy the state ... |

Hello, I have a column in database table defined with datatype BLOB. It is used to store large xmls. (After some reading, I understand that CLOB should have been used for this purpose.
