1.mysql 讀（querySql查詢方式）到mysql寫    執行命令是：

python datax/bin/datax.py datax/job/test.json 

{
  "job":{
    "content":[
      {
        "reader": {
          "name": "mysqlreader",
          "parameter": {
            "username": "root",
            "password": "root",
            "connection": [
              {
                
 
"querySql": [
                  "select * from wmj_owner where id = 2;"
                ],
                "jdbcUrl": [
                  "jdbc:mysql://127.0.0.1:3306/yyl_ry"
                ]
              }
            ]
          }
        },
        "writer":{
          "name":"mysqlwriter",
          
 
"parameter":{
            "column":[
              "user_name"
            ],
            "connection":[
              {
                "jdbcUrl": "jdbc:mysql://127.0.0.1:3306/yyl_ry",
                "table":[
                  "wmj_orders"
                ]
              }
            ],
            "password":"root",
            
 
"username":"root"
          }
        }
      }
    ],
    "setting":{
      "speed":{
        "channel":"1"
      }
    }
  }
}

2.mysql 讀（where動態方式查詢方式）到mysql寫        執行命令是：

python datax/bin/datax.py datax/job/test.json -p "-Did=3"

{
  "job":{
    "content":[
      {
        "reader": {
          "name": "mysqlreader",
          "parameter": {
            "username": "root",
            "password": "root",
            "column": [
              "name"
            ],
            "where": "id=${id}",
            "splitPk": "id",
            "connection": [
              {
                "table": [
                  "wmj_owner"
                ],
                "jdbcUrl": [
                  "jdbc:mysql://127.0.0.1:3306/yyl_ry"
                ]
              }
            ]
          }
        },
        "writer":{
          "name":"mysqlwriter",
          "parameter":{
            "column":[
              "user_name"
            ],
            "connection":[
              {
                "jdbcUrl": "jdbc:mysql://127.0.0.1:3306/yyl_ry",
                "table":[
                  "wmj_orders"
                ]
              }
            ],
            "password":"root",
            "username":"root"
          }
        }
      }
    ],
    "setting":{
      "speed":{
        "channel":"1"
      }
    }
  }
}
