Question

我们在pentaho CDE上设置了一个嵌套的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

我们已经使用该查询设置了条形图组件。

但条形图没有结果。

Pentaho cde是否支持嵌套的sql Query

Answer 1

Pentaho cde支持嵌套的sql Query。

    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运行并查看。

如果条形图中没有结果。

=＆GT;您可以做一件事，转到仪表板位置，这意味着您将仪表板保存在该位置的哪个位置。

=＆GT;在这些位置CDA文件就在那里。选择该CDA文件，然后单击＆＃34; 在新窗口中打开＆＃34;。在出现一个新窗口并选择该查询并查看结果是否显示之后。

=＆GT;如果显示结果，则sql中没有问题。

谢谢..
