Обсуждение: Fail to write BLOB - no exception thrown
Hi
I am unable to write an image file into postgres using the jdbc7.1-1.2.jar driver.
Application server runs on NT, Postgres 7.1.3 on Linux 7.1.
No exception or error is generated and the transcation appears to go through.
Yet no record is recieved into postgres.
Code:
Class.forName("org.postgresql.Driver");
Connection conn = DriverManager.getConnection("jdbc:postgresql://192.168.0.50:5432/mydb","administrator","password");
Connection conn = DriverManager.getConnection("jdbc:postgresql://192.168.0.50:5432/mydb","administrator","password");
File file = new File("d:/Temp/testimage.gif");
FileInputStream fis = new FileInputStream(file);
FileInputStream fis = new FileInputStream(file);
conn.setAutoCommit(false);
PreparedStatement ps = conn.prepareStatement("INSERT INTO IMAGES VALUES (?, ?)");
ps.setString(1, file.getName());
Long length = new Long(file.length());
ps.setString(1, file.getName());
Long length = new Long(file.length());
ps.setBinaryStream(2, fis,length.intValue());
ps.executeUpdate();
ps.close();
fis.close();
ps.executeUpdate();
ps.close();
fis.close();
This code works for other dbs.
