> @sandynz Hi, Can you provide your table schema and sharding configuration?
I have used the master branch to test, the `INSERT INTO ... ON DUPLICATE KEY
UPDATE ...` statement can be executed normally.
Hi @strongduanmu , I tested it on lastest master branch again, commit:
bfb1486549e9908f8784210fe2100f1c5fdd212d (2020-08-19), run
`org.apache.shardingsphere.proxy.Bootstrap`, it doesn't work.
My config-sharding.yaml
```

String status = "PAID";
try (PreparedStatement statement =
connection.prepareStatement("insert into t_order (order_id, user_id, status)
