假设我在一个特定的值中有以上值 table.Now 我需要汇总拒绝数量并将拒绝原因显示为列，拒绝数量显示为按月和按月计算的值
假设我需要 5 月 2014.The 的数据，上述值列表的报告输出应该是：-
PART NAME 5th cap side dross Casting Broken Bend in Casting Bend in Dand Angular Hole Shrinkage Unclean Bend

请帮助我并指导我通过 sql 或 pl sql 在 oracle 中实现此任务。
试试这个：
SELECT *
FROM your_table_name
PIVOT (COUNT(REJECTED_REASON)
FOR REJECTED_REASON IN('reason1', 'reason2', 'reason3' ....))
;
最好的方法是像 Aramillo 所说的那样使用动态枢轴。 Oracle 有类似的东西，它是 pivot xml 子句，但我有一些查询要问你，它动态地完成工作而无需 xml 操作。正如您所说，您只需要显示报告，因此经过一些格式化后，以下查询的输出将适合您的情况：
select part_name ,
rtrim(xmlagg(xmlelement(e,rejected_reason,',').extract('//text()')),',')
|| chr(10) /*new line char */ ||
rtrim(xmlagg(xmlelement(e,cnt,',').extract('//text()')),',')
from (
select part_name,
rejected_reason,
row_number() over (partition by part_name, rejected_reason order by rejected_reason) as rn,
count(*) over (partition by part_name, rejected_reason order by rejected_reason) as cnt
from your_table
order by part_name,
rejected_reason
)
where data_column = 'MAY 2014'
and rn = 1 -- to avoid duplicates in groups
group by part_name;
请copy/paste查看结果。
SELECT part_name
, sum(decode(reject_reason, 'Metal chips in port face', 1, 0)) "Metal chips in port face"
, sum(decode(reject_reason, 'Angular hole Shrinkage', 1, 0)) "Angular hole Shrinkage"
