NullPointerException when executing PreparedStatement on Oracle DB to insert Blob
In my app I used a File instead of a Blob for the method input and have done the BLOB insert this way:
public void insertBlob(String filedesc, File file) { Connection con = DriverManager.getConnection(url, username, password); InputStream input = new FileInputStream(file); PreparedStatement pstmt = con.prepareStatement( "insert into schema.table values(?,?)"); pstmt.setString(1, filedesc); pstmt.setBinaryStream(2, input); pstmt.execute();}Maybe you will need some try-catch, but I hope this will help You.
Try using the *createTemporary(yourConnection, false, oracle.sql.BLOB.DURATION_CALL)* function on the oracle.sql.BLOB to create your instance. After that just use the setBytes(...) to set its content.
One remark: prepStmt.setDate(2, erzeugung); is simpler.
I would have expected a simple:
InputStream blobIS = pdf.getBinaryStream();prepStmt.setBlob(4, blobIS, pdf.length());... pdf.free();
