Pentaho CDE 嵌套 sql 查询

Question

我们在 pentaho CDE 上设置了一个嵌套 SQL 查询。 查询：

select dataissue.value,count(value) as nbreticket,substring(issue.entry,1,3) 
from DataIssue,issue where field = 'version(s)_corrigée(s)' 
and dataissue.issue = issue.id and issue in ( select issue
from dataissue,issue where dataissue.issue = issue.id and value = 'récit' 
and substring(issue.entry,1,3) = 'ema' ) and issue in ( select issue 
from dataissue,issue where dataissue.issue = issue.id and value = 'Fermée' 
and substring(issue.entry,1,3) = 'ema' ) and issue in ( select issue 
from dataissue,issue where dataissue.issue = issue.id 
and field = 'point_d_effort' and substring(issue.entry,1,3) = 'ema' ) 
group by dataissue.value

我们已经为该查询设置了一个条形图组件。

但是条形图中没有结果。

Pentaho cde 是否支持嵌套 sql 查询

Answer 1

Pentaho cde 支持嵌套 sql 查询。

    SELECT SUBSTRING(issue.entry,1,3),dataissue.value,COUNT(VALUE) AS nbreticket
FROM DataIssue,issue WHERE FIELD = 'version(s)_corrigée(s)' 
AND dataissue.issue = issue.id AND issue IN ( SELECT issue
FROM dataissue,issue WHERE dataissue.issue = issue.id AND VALUE = 'récit' 
AND SUBSTRING(issue.entry,1,3) = 'ema' ) AND issue IN ( SELECT issue 
FROM dataissue,issue WHERE dataissue.issue = issue.id AND VALUE = 'Fermée' 
AND SUBSTRING(issue.entry,1,3) = 'ema' ) AND issue IN ( SELECT issue 
FROM dataissue,issue WHERE dataissue.issue = issue.id 
AND FIELD = 'point_d_effort' AND SUBSTRING(issue.entry,1,3) = 'ema' ) 
GROUP BY dataissue.value

你可以把这些sql放出来运行看看。

如果条形图中没有结果。

=>您可以做一件事，转到您的仪表板位置，这意味着您将仪表板保存在该位置的哪个位置。

=> 在这些位置有 CDA 文件。选择该 CDA 文件并单击“在新窗口中打开”。之后会出现一个新窗口并选择该查询并查看结果是否显示。

=>如果显示结果，则该sql没有问题。
