Homogeneous Batching with LOB Columns

When the HOMOGENEOUS_BATCH and ENABLE_LOB_LOCATORS properties are set to true, your client application cannot mix LOB and non-LOB prepared statement setter methods in the same batch.

For example, this is invalid:

String sql = "update members SET catchphrase = ? WHERE member_id = ?";
prep_stmt = connection.prepareStatement(sql);
prep_stmt.setString(1, "Push the button, Frank!");
prep_stmt.setLong(2, 45129);
prep_stmt.addBatch();
Clob myclob = con.createClob();
myclob.setString(1, "Hi-keeba!");
prep_stmt.setClob(1, myclob);
prep_stmt.setLong(2, 45130);
prep_stmt.addBatch();
pstmt.executeBatch();

where catchphrase is a column of type text. This code fails because the setString method and the setClob method are used in the same batch for the same column.
