"Invalid data conversion" in DB2 with prepared statements and batch
<p>I am using JDBC to create a temporary table, add records to it (with prepared statement and batch) and then transfer everything to another table:</p>

<pre><code>        String createTemporaryTable = "declare global temporary table temp_table (RECORD smallint,RANDOM_INTEGER integer,RANDOM_FLOAT float,RANDOM_STRING varchar(600)) ON COMMIT PRESERVE ROWS in TEMP";

        statement.execute(createTemporaryTable);

        String sql = "INSERT INTO session.temp_table (RECORD,RANDOM_INTEGER,RANDOM_FLOAT,RANDOM_STRING) VALUES (?,?,?,?)";
        PreparedStatement preparedStatement = connection.prepareStatement(sql);

        float f = 0.7401298f;
        Integer integer = 123456789;
        String string = "This is a string that will be inserted into the table over and over again.";

        // add however many random records you want to the temporary table
        int numberOfRecordsToInsert = 35000;

        for (int i = 0; i &lt; numberOfRecordsToInsert; i++) {

            preparedStatement.setInt(1, i);
            preparedStatement.setInt(2, integer);
            preparedStatement.setFloat(3, (float) f);
            preparedStatement.setString(4, string);
            preparedStatement.addBatch();

        }

        preparedStatement.executeBatch();

        // transfer everything from the temporary table just created to the main table
        String transferFromTempTableToMain = "insert into main_table select * from session.temp_table";
        statement.execute(transferFromTempTableToMain);
</code></pre>

<p>This works fine up to about 30000 records in this example. However, if I were to insert say 35000 records I get the following error:</p>

<blockquote>
  <p>Invalid data conversion: Requested conversion would result in a loss
  of precision of 32768. ERRORCODE=-4461, SQLSTATE=42815</p>
