import java.sql.Connection
import java.sql.Driver
import java.sql.PreparedStatement
Class clazz = Class.forName("com.mysql.jdbc.Driver");
Driver driver = clazz.newInstance() as Driver;
String url =
"jdbc:mysql://127.0.0.1:3307/sharding_db?rewriteBatchedStatements=false&allowMultiQueries=false";
Properties info = new Properties();
info.setProperty("user", "root");
info.setProperty("password", "root");
Connection conn = driver.connect(url, info);
String delSQL = "delete from t_order where order_id = ?;"
PreparedStatement ps = conn.prepareStatement(delSQL)
for (i in 0..<5) {
ps.setObject(1, i);
ps.addBatch();
}
def batch = ps.executeBatch()
println batch
```
Case2:Execute batch delete during incremental data import phase of migration

ps.addBatch();
}
def batch = ps.executeBatch()
println batch
