Question

我正在尝试在MySql中进行搜索，但无法弄清楚如何设置查询。我知道我的数据库设置有点混乱，但我现在坚持了。我想以任何方式搜索attrValue列并查找唯一字符串，在找到之后我想将其与10个连续（以下）结果一起显示。在我的情况下，这甚至可能吗？

以下是我的尝试：

SELECT attrName, attrValue
FROM def_servpath_0001_weatherstation
JOIN (
SELECT *
FROM def_servpath_0001_weatherstation
WHERE attrValue = '8:0:0,1.9.2015'
)t
LIMIT 11

但我没有运气。有没有人有任何建议？

Answer 1

SELECT attrName, attrValue
FROM def_servpath_0001_weatherstation
WHERE attrValue = '8:0:0,1.9.2015'

UNION 

SELECT a.attrName, a.attrValue
FROM def_servpath_0001_weatherstation a
JOIN (
SELECT *
FROM def_servpath_0001_weatherstation
WHERE attrValue = '8:0:0,1.9.2015'
)b ON a.recvTimeTs=b.recvTimeTs AND a.attrValue <>'8:0:0,1.9.2015'
LIMIT 10
