使用 SQL Server 查询 JIRA 以返回历史状态

Question

2014 年 3 月 20 日更新

按照史蒂夫的以下建议，我提出了以下建议：

use JiraDB;
GO
With OrderedBugList AS
(
    SELECT  cg.issueid as "cgIssueID"
        ,cg.AUTHOR as "cgWho"
        ,cg.CREATED as "cgCreated"
        ,cg.ID as "cgID"
        ,ROW_NUMBER() OVER (PARTITION BY cg.issueid ORDER BY cg.created DESC) as RowNumber
FROM changegroup cg
where cg.CREATED < '2014-01-10'
)

select  obl.RowNumber, 
    obl.cgCreated, 
    obl.cgID, 
    obl.cgIssueID, 
    obl.cgWho,
    ji.pkey,
    ji.summary,
    ci.NEWSTRING,
    ci.OLDSTRING 
from OrderedBugList obl
LEFT OUTER JOIN jiraissue ji on ji.ID = obl.cgIssueID
LEFT OUTER JOIN changeitem ci on ci.groupid = obl.cgID
where   obl.RowNumber = 1
and     ji.issuetype = 1
and     ci.FIELD = 'Status'

它没有给我想要的一切，但它确实解决了我描述的问题。

我正在尝试创建项目的历史视图，以展示错误指标的趋势。

我在 MS SQL Server 2008 R2 中使用 Atlassian JIRA (v4.4.4#664-r167664)

我使用的是标准（来自Jira sample SQL Queries）：

SELECT JI.pkey, STEP.STEP_ID
FROM (SELECT STEP_ID, ENTRY_ID
      FROM OS_CURRENTSTEP
      WHERE OS_CURRENTSTEP.START_DATE < '<your date>'
UNION SELECT STEP_ID, ENTRY_ID
      FROM OS_HISTORYSTEP
      WHERE OS_HISTORYSTEP.START_DATE < '<your date>'
      AND OS_HISTORYSTEP.FINISH_DATE > '<your date>' ) As STEP,
(SELECT changeitem.OLDVALUE AS VAL, changegroup.ISSUEID AS ISSID
      FROM changegroup, changeitem
      WHERE changeitem.FIELD = 'Workflow'
      AND changeitem.GROUPID = changegroup.ID
UNION SELECT jiraissue.WORKFLOW_ID AS VAL, jiraissue.id as ISSID
      FROM jiraissue) As VALID,
jiraissue as JI
WHERE STEP.ENTRY_ID = VALID.VAL
AND VALID.ISSID = JI.id
AND JI.project = <proj_id>;

但是我发现这给了我错误的结果集。

我已经到变更物品表去尝试挖掘我的金子。 :)

SELECT cg.issueid 
  ,ji.pkey
  ,ji.SUMMARY 
  ,ci.FIELD
  ,CAST(ci.NEWSTRING AS varchar) AS NEWST
  ,CAST(ci.OLDSTRING AS varchar) AS OLDST
  ,cg.CREATED
  FROM changegroup cg
  LEFT OUTER JOIN changeitem ci on cg.ID = ci.groupid
  LEFT OUTER JOIN jiraissue ji on cg.issueid = ji.ID 
  where ci.FIELD = 'status'
  and ji.issuetype = 1
  and ji.PRIORITY = 1
  and cg.CREATED < '2012-09-15'
  order by ji.pkey, cg.created DESC, cg.issueid

我的最后一个绊脚石是尝试只返回一条记录，即在所需时间范围内具有状态的一条记录。上面的查询返回一个结果集，它给了我类似的东西：

• issueid / pkey / Summary / FIELD / NEWST / OLDST / CREATED
• **32298 / QST-9693 / 错误摘要 1 / 状态 / 已关闭 / 已解决 / 2012-09-12 17:11:46.560
• 32298 / QST-9693 / 错误摘要 1 / 状态 / 已解决 / 进行中 / 2012-09-07 17:33:24.397
• 32298 / QST-9693 / 错误摘要 1 / 状态 / 进行中 / 打开 / 2012-09-07 17:32:40.623
• **32404 / QST-9789 / 错误摘要 2 / 状态 / 已解决 / 进行中 / 2012-09-13 14:41:24.080
• 32404 / QST-9789 / 错误摘要 2 / 状态 / 进行中 / 打开 / 2012-09-10 17:43:07.663

我只想返回标有双星号 (**) 的记录

请告诉我如何做到这一点:)

提前致谢。

你认为你可以创建一个 SQL Fiddle 来让它更容易玩吗：http://sqlfiddle.com/

您应该能够通过以下方式实现您想要的，即每个组的第一名：

ROW_NUMBER() OVER (PARTITION BY...)
