如何在2个mysql表中选择最大值行？

Question

我有两张表如下：

表：访客

---------------------
|     Code    |Contr|
|-------------------|
|225919528553 | 1003|
|-------------------|
|130324727131 | 1004|
|-------------------|
|353952972425 | 1010|
|-------------------|
|997498622785 | 1014|
|-------------------|
|
|
|

表：产品

-----------------------------
|    Code     | Name| Color |
|----------------------------
|225919528553 | Pen | Balck |
|----------------------------
|130324727131 | Book| White |
|----------------------------
|353952972425 | Fan | Black |
|----------------------------
|997498622785 | DVD |  Red  |
|----------------------------
|
|
|

我希望显示以下"Contr"列的更多值：

|    Code     | Name| Color | Contr |
|------------------------------------
|997498622785 | DVD |  Red  | 1014  |
|------------------------------------
|353952972425 | Fan | Black | 1010  |
|------------------------------------
|130324727131 | Book| White | 1004  |
|------------------------------------
|225919528553 | Pen | Balck | 1003  |
|------------------------------------
