I use the same statement object to execute multiple queries, but from the second query, the error shown above will be produced after each query. For instance, if I execute query for 5 times, the error log will be shown for 4 times. Although it does not affect the result of each query, I want to figure out the reason. Should I add some properties when create the connection? the example code:

   `Statement stmt = null; 
    for (String sql : queries) {
        try {
            if (stmt == null) {
                stmt = conn.createStatement();
            }
            stmt.executeQuery(sql);
        } catch (Exception e) {
            log.error("error when execute clickhouse query", e);
        } 
    }`

thx
