I wanted to learn how to use Stored Procedure when inserting BLOB data on my MSSQL Table.
final File blobIn = new File("spring2004.jpg");
final InputStream blobIs = new FileInputStream(blobIn);
final File clobIn = new File("large.txt");
final InputStream clobIs = new FileInputStream(clobIn);
final InputStreamReader clobReader = new InputStreamReader(clobIs);
jdbcTemplate.execute(
"INSERT INTO lob_table (id, a_clob, a_blob) VALUES (?, ?, ?)",
new AbstractLobCreatingPreparedStatementCallback(lobhandler) { (1)
protected void setValues(PreparedStatement ps, LobCreator lobCreator)
throws SQLException {
ps.setLong(1, 1L);
lobCreator.setClobAsCharacterStream(ps, 2, clobReader, (int)clobIn.length()); (2)
lobCreator.setBlobAsBinaryStream(ps, 3, blobIs, (int)blobIn.length()); (3)
}
}
);
blob开发者_运维百科Is.close();
clobReader.close();
The spring framework 2.5 documentation uses jdbc template. But this is a NO-NO in my case. I hope somebody could share their insights on how to do insert and retrieve the data as an inputstream.
I have been trying to google for the answer but not enough resource on this can be found.
You can try with Spring + JPA with a native query or with JpaDaoSupport.
There are good answers in the following links:
- Native query
- JpaDaoSupport
