Question

I’m trying to store MediumBlob data in MySQL using java. But I have no success to retrieve the data.

To store I’m using:

PreparedStatement = stmt conn.prepareStatement("UPDATE INTO table VALUE(?)");
ByteArrayInputStream bais = new ByteArrayInputStream(data);
stmt.setBinaryStream(position, bais, data.length);

Is there correcty?

Answer 1

I fix it!!!!

The problem was when I was retrieving the data. I was calling:

ResultSet.getClob

But I should call:

ResultSet.getBinaryStream

I have used setBinaryStream to input data!

This was confusing because I have a Clob field, and I was expecting retrieving a Clob field in Java code!
