Flink有个问题，就是这整个写法我感觉都是table api的语法啊，没有用到flink-connector-jdbc啊？flink-connector-jdbc在这里面起了什么作用呢？ String createTableDDL = "CREATE TEMPORARY TABLE ams_datasync_test (\n" +
" id INT,\n" +
" PRIMARY KEY (id) NOT ENFORCED\n" +
") WITH (\n" +
" 'connector' = 'jdbc',\n" +
" 'url' = 'jdbc:dm://10.16.26.116:5236/AMS_PCRW_ONLINE',\n" +
" 'username' = 'AMS_PCRW_ONLINE',\n" +
" 'password' = '2023',\n" +
" 'table-name' = 'ams_datasync_test',\n" +
" 'driver' = 'dm.jdbc.driver.DmDriver'\n" +
")";

    tableEnv.executeSql(createTableDDL);
    tableEnv.from("InputTable").insertInto("ams_datasync_test").execute();我这么写确实增删改也没问题，那flink-connector-jdbc在这里面好像也没起什么作用啊？有点迷糊
