Question

table structure image score breakdown我有一张名为得分的高尔夫球得分表。列标题是高尔夫球手，golf_course，h1，h2，h3等等到h18。我有一个表格，根据0 =没有得分，1 =柏忌，2 =标准杆，3 =小鸟，4 =老鹰，在每列中添加得分。我想要实现的是一个声明，可以返回每行没有得分，柏忌，小鸟，小鸟或老鹰的数量。任何帮助我都会非常感激。

Answer 1

感谢Subin C Poonamgode，

你让我走上正轨。我调整了你的解决方案，使下面的代码工作

jena version 3.0.0
ubuntu 15.04
intellij 14.1.4
java version "1.8.0_60"
Java(TM) SE Runtime Environment (build 1.8.0_60-b27)
Java HotSpot(TM) 64-Bit Server VM (build 25.60-b23, mixed mode)
whereis java: /jvm/java-8-oracle/jre/bin/java

为了获得我需要的所有其他条件，我只是将CASE 0更改为1,2,3和4。再次感谢:-)

这可能有效。

希望这会有所帮助。
