Hi All,

I'm trying to bulk load some MAC addresses using a prepared statement.
But I keep on getting an error about incorrect datatype (complains that
I'm trying to insert "character varying"). Bellow is an example of the
code that I'm using:

try {

Class.forName("org.postgresql.Driver");
conn = DriverManager.getConnection(jdbc_url, jdbc_user,
jdbc_pass);

PreparedStatement stmt = conn.prepareStatement("insert into
log (date, time, mac, network) values (?,?,?,?)");

while (inputLineIterator.hasNext()) {
String[] line = inputLineIterator.next();
if (line == null) {
continue;
}
stmt.setDate(1, new java.sql.Date(
dfmt.parse(line[0]).getTime()) );
stmt.setDate(2, new java.sql.Date(
tfmt.parse(line[1]).getTime()) );
stmt.setString(3, line[2]);
stmt.setString(4, line[3]);
stmt.execute();
}

stmt.close();
}

Any recommendations?

Cheers

Steve
