我正在尝试在 MySql 中进行搜索，但不知道如何设置查询。我知道我的数据库设置有点困惑，但我现在坚持下去。我想以任何方式搜索 attrValue 列并查找唯一的字符串，找到它后我想将其与 10 个连续(以下)结果一起显示。对于我来说这可能吗？
这是我尝试过的:
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。有人有什么建议吗？
