我试图结合一些NBA数据,方块得分和先进的球员统计。我现在的问题是:
select boxes.GNO, boxes.NAME, boxes.DATE, advstat.YEAR, advstat.NAME, advstat.AGE
from boxes left join advstat on boxes.NAME=advstat.NAME
group by boxes.NAME, boxes.GNO having boxes.GNO = 1;
boxes.gno=1只是为了限制此时返回的数据,最终我将返回boxes表中所有游戏的数据。
通过上面的查询,我得到以下输出:
+------+------------------+------------+------+------------------+------+
| GNO | NAME | DATE | YEAR | NAME | AGE |
+------+------------------+------------+------+------------------+------+
| 1 | Al Horford | 2017-10-17 | 2008 | Al Horford | 21 |
| 1 | Aron Baynes | 2017-10-17 | 2013 | Aron Baynes | 26 |
| 1 | Derrick Rose | 2017-10-17 | 2009 | Derrick Rose | 20 |
| 1 | Dwyane Wade | 2017-10-17 | 2004 | Dwyane Wade | 22 |

| 1 | Jae Crowder | 2017-10-17 | 2013 | Jae Crowder | 22 |
| 1 | Jaylen Brown | 2017-10-17 | 2017 | Jaylen Brown | 20 |

| 1 | Kyrie Irving | 2017-10-17 | 2012 | Kyrie Irving | 19 |
| 1 | LeBron James | 2017-10-17 | 2004 | LeBron James | 19 |
| 1 | Marcus Smart | 2017-10-17 | 2015 | Marcus Smart | 20 |
| 1 | Semi Ojeleye | 2017-10-17 | NULL | NULL | NULL |
| 1 | Shane Larkin | 2017-10-17 | 2014 | Shane Larkin | 21 |
| 1 | Terry Rozier | 2017-10-17 | 2016 | Terry Rozier | 21 |
| 1 | Tristan Thompson | 2017-10-17 | 2012 | Tristan Thompson | 20 |
+------+------------------+------------+------+------------------+------+
这几乎是对的。但是我需要advstat.year来匹配年份(box.date)。如果我加上..
其中year(boxes.date)=advstat.year,则不包括空数据,这不是我想要的。我需要这张表看起来像上面那样,只是年份在两张表之间正确排列。
任何帮助都将不胜感激!干杯!
