9/2 周坤:第五代时间管理 4/10 9/2 SQL Server 2012 深入解析和性能优化  P314/490 9/2 Pro T-SQL2019 P25/410 以后每天都写写日记吧 光写Joke也没人看 虽然写日记也不一定有人看。 早起 看了一集时间管理 具体也记不大清了,刚刚又翻了一下视频 目录如下: 习惯的定义 习惯的判断 习惯与舒适区 早上和Jack OuYang去了F7,去了解IOS开发 匆匆而过,试验成功VNC远程连接, 了解到Seven也所知不多后,就回Qbus了。 中午,在咨询了QQ游戏群里的伞老(IOS开发)后, 给了一个HBuilder的连接让自己研究, 我把这个连接回邮件给大家后,就决定让OuYang自己琢磨了。 中午12点半, 出去去生活区,QELC(QSMC English Learning Center)学习BEC英语 学的是单词第四组 1/16-4/16上了四节小课,然后就回办公室了, 回来后OuYang还在折腾HBuilder,效率有些低 让他慢慢折腾吧。 剩下点时间,看书《SQL Server 2012 深入解析和性能优化》 看了SQLDiag的内容,后半章,第一遍先把概念了解一下 SQL Diag有好多模板,最好都能实践一下,以后都要多动手,现在都停留在理论阶段。 临下班,和Steven讲了一下C#大项目需要添加的功能,就下班了。 C# 还是他强,还是让大家都做自己擅长的事情,我还是搞搞我的SQL。 下班的时候,把大宝幼儿园的冬天被子送给了Tacey,夏天的昨天已经送了。 回到家,晚饭,和大宝聊天,发现学校里,同班同学好多都好鸡血, 什么新学期的课估计暑假都学了,新概念啥的都会, 汗,是不是我们教育太放松了,没有抓紧补习班, 就像跑一千米,别人都跑了一圈了,我们才刚刚在起跑线起跑,女儿压力是有些大, 好好开导一下后,还是以后要多给予支持,慢慢追上这些抢跑的同学。 写到这儿,已经快8点了, 以后,我也每天花点时间在SQL上,看看电子书,慢慢长进吧。 书名《Pro T-SQL 2019》看到P25 DECIMAL/NUMERIC,SMALLMONEY, MONEY,Approximate Number Data Types,Converting Number Data Types,String Data Types,Character String Data Types,CHAR and VARCHAR,TEXT,Unicode String Data Types,NCHAR and NVARCHAR,NTEXT,Binary String Data Types,BINARY and VARBINARY,IMAGE 晚安,洗洗睡吧。 业余爱好: 昨天群里有人要找资料,是PowerBI的资料,碰巧我以前收集过很多,加了百度网盘好友,都分享给他了,希望能帮助。 昨天群里有人要找书《岂不怀归》,这是本今年新出的书,普通的鸠摩搜书,和大力盘搜索都宣告失败, 但是我不放弃,继续人肉,经过N多网页的试错,找到了资源 链接:https://pan.baidu.com/s/1hgdXajBX42UJQ5J5RJEspA 提取码:fei9 复制这段内容后打开百度网盘手机App,操作更方便哦 哈哈,我找东西也还是很强的,不过,这次找到也算是运气, 不是什么新书就能找到的,新书找不到的概率很大。   Torn还在继续,新的一天,飞行榜又要开始霸榜了:)

# 📊 HiddenMerit Daily · Issue 59 > **Focus on Database Frontiers, Practical Insights for DBAs** > July 21, 2026 | 5 Selected Global Breaking News ## 01|Oracle Issues Urgent Warning: July 21 Release Update to Fix Large Number of High‑Risk Vulnerabilities, Immediate Deployment Recommended On July 13, Oracle issued an urgent security warning, strongly recommending that all customers running supported Oracle Database versions (including Oracle Database 19c and Oracle AI Database 26ai) immediately test and deploy the Release Update (RU) after its release on July 21. **Background**: New frontier AI models are significantly lowering the barrier to discovering and exploiting software vulnerabilities – these models can identify weaknesses, analyse software changes, reverse‑engineer security patches, and develop potential attack paths at unprecedented speed and scale. AI models are also becoming increasingly adept at combining multiple weaknesses across the application and data stack into complex attacks, even when individual weaknesses do not themselves pose a serious risk. As a result, protecting systems solely at the network or application layer is no longer sufficient; enterprises must protect the entire technology stack. **Fixes Included in This RU**: Oracle has collaborated with state‑of‑the‑art models from Anthropic and OpenAI to proactively identify and fix potential […]

# 📊 HiddenMerit Daily · Issue 56 > **Focus on Database Frontiers, Practical Insights for DBAs** > July 6, 2026 | 5 Selected Global Breaking News ## 01|Kingware Releases Manufacturing Scenario Database Evolution White Paper: SQL Server Replacement Enters “Deep Water” On July 5, CETC Kingware published a technical article titled “Database Evolution in Manufacturing Scenarios: How Kingware Replaces SQL Server,” pointing out that the data surge on industrial shop floors has exceeded the processing capacity of single‑node systems. Traditional database architectures that rely on vertical scaling are facing unprecedented performance challenges. Over the next 1‑3 years, manufacturing enterprises will no longer face only the “choice of replacement,” but must answer the strategic question: “How do we build an autonomous data foundation in the context of de‑IOE?” **Three Paradigm Shifts**: 1. **Hybrid Workloads Become the Norm**: The IT architecture of modern factories is shifting from separated OLTP and OLAP to HTAP mode. The same data system must simultaneously handle tens of thousands of device instruction writes per second and minute‑level production report analysis. 2. **Distributed Architecture Becomes a Hard Requirement**: When a single table exceeds 100 million rows with daily increments exceeding 1 million rows, the index maintenance cost of […]
