如何在oracle10g中拆分多列中的列数据？

Question

我们有3列METRIC，count，SETS和Data的表格如下：

    "METRIC"             "SET1"   "SET2"
    FOR_PEOPLE_LIKE_ME      0         0    
    FOR_YOUNG_PEOPLE        1         1
    GOOD_TASTE              0         0    
    HIGH_SATISFACTION       2         0
    FOR_STATUS_ORIENTED     0         3

我想通过“SET1”和“SET2”分割数据。我应该采取什么方法 使用？我想要的结果是：

{{1}}

Answer 1

您正在寻找过滤后的聚合：

select metric, 
       sum(case sets when 'SET1' then "COUNT" end) as SET1,
       sum(case sets when 'SET2' then "COUNT" end) as SET2
from the_table
group by metric;
