Question

我在调用数据库时使用以下脚本：

SELECT 
 1.0*(COUNT(*) FILTER(WHERE "stitch_jira"."issues"."fields__status__statusCategory__name"='Done'
 AND "stitch_jira"."issues"."fields__project__key"='FLUM'
 AND "stitch_jira"."issues"."fields__issuetype__name"='Task'
 OR "stitch_jira"."issues"."fields__issuetype__name"='Story'))/
 (COUNT(*) FILTER(WHERE "stitch_jira"."issues"."fields__status__statusCategory__name" IN('To Do','In Progress','Done')
 AND "stitch_jira"."issues"."fields__project__key"='FLUM'
 AND "stitch_jira"."issues"."fields__issuetype__name"='Task'
 OR "stitch_jira"."issues"."fields__issuetype__name"='Story'))
FROM "stitch_jira"."issues"

基本上，应该获得完成的任务和故事，然后将其除以任务和故事的总数。结果似乎无法证明这一点。如果我仅执行任务或仅执行故事，但当我同时执行两个任务时，则IT工作正常。

我哪里出错了？

正确答案如下：

SELECT 
 1.0*
 ((COUNT(*) FILTER(WHERE "stitch_jira"."issues"."fields__status__statusCategory__name"='Done'
 AND "stitch_jira"."issues"."fields__project__key"='FLUM'
 AND "stitch_jira"."issues"."fields__issuetype__name"='Task'))
 +
 (COUNT(*) FILTER(WHERE "stitch_jira"."issues"."fields__status__statusCategory__name"='Done'
 AND "stitch_jira"."issues"."fields__project__key"='FLUM'
 AND "stitch_jira"."issues"."fields__issuetype__name"='Story')))
 /
 ((COUNT(*) FILTER(WHERE "stitch_jira"."issues"."fields__status__statusCategory__name" IN('To Do','In Progress','Done')
 AND "stitch_jira"."issues"."fields__project__key"='FLUM'
 AND "stitch_jira"."issues"."fields__issuetype__name"='Task'))
 +
 (COUNT(*) FILTER(WHERE "stitch_jira"."issues"."fields__status__statusCategory__name" IN('To Do','In Progress','Done')
 AND "stitch_jira"."issues"."fields__project__key"='FLUM'
 AND "stitch_jira"."issues"."fields__issuetype__name"='Story')))
FROM "stitch_jira"."issues"

问题是OR条件的绑定不够紧密，它正在将计算中的数据提取到过滤后的项目之外。
