Question

我使用以下查询创建排名列表：

 SELECT Count(a2.performance) rank, 
       a1.performance, 
       a1.wind, 
       a1.name, 
       a1.surname, 
       a1.dob, 
       a1.prov, 
       a1.pos, 
       a1.place, 
       a1.date 
FROM   men a1, 
       men a2 
WHERE  a1.performance > a2.performance 
        OR ( a1.performance = a2.performance 
             AND a1.name = a2.name 
             AND a1.surname = a2.surname 
             AND a1.wind = a2.wind 
             AND a1.dob = a2.dob 
             AND a1.prov = a2.prov 
             AND a1.pos = a2.pos 
             AND a1.place = a2.place 
             AND a1.date = a2.date 
             AND a1.event = '100m' 
             AND a1.year = '2016' ) 
GROUP  BY a1.name, 
          a1.surname, 
          a1.performance 
ORDER  BY `a1`.`performance` ASC

我的表格如下：

| id | event | performance | wind | name | surname | dob | prov | pos | place | date | year |

我的排名列表完美无缺，但我还想为event和year字段添加一个条件，这不是输出的一部分。如果我有year和event条件，它什么都不做。任何可以提供帮助的人都可以过滤那些字段。

这就是表格的样子：

|id|event|performance|wind|name|surname|dob|prov|pos|place|date|year|
---------------------------------------------------------------------
| 1|100m |   10.00   |2.0 |John|  Coe  |   |    |   |     |    |2016|
| 2|100m |   10.01   |2.0 |John| Smith |   |    |   |     |    |2017|
| 3|200m |   20.10   |2.0 |  U |  Bolt |   |    |   |     |    |2016|
| 4|100m |   10.05   |2.0 |Pete|  Doe  |   |    |   |     |    |2016|

这就是我得到的：

|rank|performance|wind|name|surname|dob|prov|pos|place|date|
| 1  |   10.00   |2.0 |John|  Coe  |   |    |   |     |    |
| 2  |   10.01   |2.0 |John| Smith |   |    |   |     |    |
| 3  |   10.05   |2.0 |Pete|  Doe  |   |    |   |     |    |
| 4  |   20.10   |2.0 |  U |  Bolt |   |    |   |     |    |

这就是我想要的条件是event = 100m和event = 2016并且它对输出的所有内容进行排名。

|rank|performance|wind|name|surname|dob|prov|pos|place|date|
| 1  |   10.00   |2.0 |John|  Coe  |   |    |   |     |    |
| 2  |   10.05   |2.0 |Pete|  Doe  |   |    |   |     |    |

Answer 1

尝试使用＆＃39; like＆＃39;而不是＆＃39; =＆＃39;

另外，我会仔细检查＆＃39; OR＆＃39; ...的语法如果a1.performance＆gt;它看起来像是否会被忽略。 a2.performance

Answer 2

我发现了这一点并对其进行了调整，并且可以解决问题：

<style>
.s4-wpcell-plain{
text-align: -webkit-center !important;
}
</style>



<table style="width:100%" cellpadding="0" cellspacing="0">
<tbody>
<tr>
<td id="MSOZoneCell_WebPartWPQ2" valign="top" class="s4-wpcell-plain">

<!-- content -->

</td>
</tr>
</tbody>
</table>
