日记-20221116
办公室好冷啊, 问了总务,要10度以下才开热泵,冷死了,小腿冷。 双十一的时候,又买了一批书 1 SQL经典实例 2 SQL编程思想 3 SQL数据分析 4 SQL基础教程 5 SQL进阶教程 6 SQL必知必会 这两天扫了一下,感觉都比较基础,也好,巩固一下, 今天在翻《SQL数据分析》,翻到后半段,是很多题目 有简单,中等,高难度之分, 看了一些简单的,发现也不简单,虽然它的实现是MySQL, 但SQL是相通的,运用到SQL Server里也是可以操作的, 等我把题目都看完了, 自己建个数据库,把表数据填充好, 做一个小的习题集,给大家做脑力训练,开阔SQL写法的思路。

# 📊 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 […]
