我有这样的事情:
CODE,ORG,TYPE,DATE是表格列。
SELECT COUNT(CODE) AS OK, ORG AS ORG
FROM EVENTS
WHERE (TYPE = 'A') and (DATE BETWEEN '2015-07-06' AND '2015-07-12')
GROUP BY ORG
结果是:
OK ORG
---------
93 1
292 2
51 3
主要问题是,总共有6个Orgs,但它们没有列出,因为COUNT没有可计算的行数,因为本周它们无法工作。
我需要始终列出ORG,如果有效COUNT值,则显示它,否则显示0.这样的事情:
OK ORG
---------
93 1
292 2
51 3
0 4
0 5
0 6
感谢您的帮助!

请你试试这个:
JLabel tabLabel = new JLabel("Tab", JLabel.LEFT);
//add new label at set location
jTabbedPane.setTabComponentAt(0, tabLabel);

您需要先从ORG
获取所有EVENTS
,然后执行LEFT JOIN
:
SELECT
ISNULL(COUNT(e.CODE), 0) AS OK,
t.ORG AS ORG
FROM(
SELECT DISTINCT ORG FROM EVENTS
)t
LEFT JOIN EVENTS e
ON e.ORG = t.ORG
AND e.TYPE = 'A'
AND e.DATE BETWEEN '2015-07-06' AND '2015-07-12'
GROUP BY t.ORG
