> Key: DERBY-3645
> URL: https://issues.apache.org/jira/browse/DERBY-3645
> Project: Derby
> Issue Type: Bug

> The following code which inserts into a table by selecting a blob column twice from another table, causes SQLException: Restore of a serializable or SQLData object of class error selecting from the table. See attached program DoubleInsertInto for full repro. Stack trace is below. Verified back to 10.3 but probably goes back further.

> "ID INT GENERATED ALWAYS AS IDENTITY PRIMARY KEY, " +
> "V BLOB(590473235) )");
> String ins1 = "INSERT INTO T_MAIN(V) VALUES (?)";
>
> PreparedStatement ps;
> ps = c.prepareStatement(ins1);
> byte[] bytes = new byte[35000];
> for (int i = 0; i < 35000; i++)
> bytes[i] = (byte) i ;
> ps.setBytes(1, bytes);
> ps.executeUpdate();
> ps.close();
