How to update Oracle Clob by using JDBC

Normal way looks like this:

    rset = pStmt.executeQuery();

Answer 1

Not sure why you call that the "normal" way, but the following works for me.

It doesn't require any retrieval of the data before updating it.

String value = "So long and thanks for all the fish";
StringReader reader = new StringReader(value);
pStmt = conn.prepareStatement("UPDATE PROGRAM_HISTORY SET DETAILS = ? WHERE ID = 12");
pStmt.setCharacterStream(1, reader, value.length());
pStmt.executeUpdate();
