How to add byte array to database with JDBC?

java Add comments

That can be achieved with a PreparedStatement and its setBytes() method.

String sql = "INSERT INTO my_table (byte_array) VALUES (?)";
PreparedStatement statement = connection.prepareStatement(sql);
byte[] buffer = somwhere.getSomeByteArray();
statement.setBytes(1, buffer);
statement.executeUpdate();
statement.close();

    Hi,

    I’m just wondering what type that should be stored as in the database. I was trying to store it first as a blob, but I get a type mismatch exception. I hope that question makes sense, I’m fairly new to db stuff and sql/jdbc.
    Thanks!

    Brendan
