JDBC:ODBC Crashes in driver when doing update

Question

I am getting a crash in the native code when trying to update a record through an updateable record set using the JDBC:ODBC bridge. I have appended the crash information at the bottom of this message gotten from the Forte output window. This is going to SQL Server 2000. Through the Beta JDBC driver everything works fine, but through ODBC it always crashes no matter what columns I pick so it doesn't seem to be data type related. I would just use the JDBC driver, but that is not a option for some of our clients. I have used Insert statements without a problem, but one of the fields in one table is a BLOB field and I don't know of any way to access it except through an updatable record set.
Does anyone have any ideas about how I might get around this?
Thanks

Answer 1

I am no guru,
but I have written BLOBS into DB2 via JDBC and I use a Prepared Statement, this works well for me.
// Below is some code I originally mimicked and It worked well for me.
// hope it it useful. I have never used SQLServer :-(
import java.io.*;
import java.sql.*;
public void insertBlob( int rowid, byte[] bindata ) {
// In this example I'm assuming there's an open, active
// Connection instance called 'con'.
// This examples uses an imaginary SQL table of the following
// form:
// CREATE TABLE blobs (
//    ROWID INT NOT NULL,
//    ROWDATA BLOB,
//    PRIMARY KEY (rowid)
try {
ByteArrayInputStream bais = new ByteArrayInputStream(bindata);
String sql = "INSERT INTO blobs ( rowid, rowdata ) VALUES ( ?, ? )";
PreparedStatement ps = con.prepareStatement(sql);
// Set up the parameter index for convenience (JDBC column
// indices start from 1):
int paramindex = 1;
// Set the first parameter, the Row ID:
ps.setInt(paramindex++, rowid);
// Now set the actual binary column data by passing the
// ByteArrayInputStream instance and its length:
ps.setBinaryStream(paramindex++, bais, bindata.length);
// Finally, execute the command and close the statement:
ps.executeUpdate();
ps.close();
} catch ( SQLException se ) {
System.err.println("Couldn't insert binary data: "+se);
} catch ( IOException ioe ) {
System.err.println("Couldn't insert binary data: "+ioe);
} finally {
con.close();
}
