This article explains OceanBase's Offline DDL implementation, showing how it rebuilds tables, manages table locks, tracks execution progress, evaluates performance, and answers common questions about lock behavior and time estimation with detailed SQL examples and log analysis.
This report objectively evaluates DeepSeek‑V3.1 on professional‑grade SQL tasks, presenting its balanced strengths in understanding, optimization, and dialect conversion, highlighting its top scores in syntax error detection and Chinese database conversion while exposing weaknesses in execution‑plan analysis and large‑SQL transformations.
This article investigates whether repeatedly assigning different or large values to MySQL session variables causes the session's memory usage to grow, presenting two experiments with functions, processlist analysis, and concluding that only large values significantly increase memory consumption.
An in‑depth August 2025 benchmark evaluates GPT‑5’s mini, nano, and chat variants on SQL understanding, optimization, and dialect conversion, revealing gpt‑5‑mini’s balanced performance, gpt‑5‑nano’s strong code‑generation accuracy, and gpt‑5‑chat’s theoretical strengths but practical shortcomings, guiding scenario‑specific model selection.
This article explains how the REPLACE INTO statement can cause mismatched AUTO_INCREMENT values between MySQL master and replica after a failover, leading to primary‑key conflicts, and provides reproduction steps, underlying mechanics, and practical mitigation strategies.
This article examines LeetCode problem 185 – the hardest SQL challenge – by preparing the Employee and Department tables, presenting two solution approaches (a subquery and a window‑function version), benchmarking their performance on large test data, and explaining why window functions are the superior choice in MySQL 8+.
This article explains how the Model Context Protocol (MCP) solves the AI integration "M×N" problem by providing a universal language for AI applications and tools, outlines its technical principles, showcases practical case studies, and promotes the accompanying book that teaches MCP from theory to implementation.
This article analyzes why an OceanBase JDBC driver fails with "Access denied" errors when deployed in Kubernetes, compares it with the MySQL driver, explains the role of IP whitelist verification, and provides step‑by‑step troubleshooting, configuration adjustments, and preventive measures.
This tutorial walks you through installing MySQL REST Service on Oracle Linux, configuring the metadata schema, using MySQL Shell in VS Code, loading the component, managing variables, handling X‑protocol settings, creating services, and authenticating via MRS, MySQL Internal, cookie or JWT, with full command‑line examples and code snippets.
This article examines how the parameter count of large language models influences their ability to generate and understand SQL, comparing small (1.5B), medium (7B), and large (32B) models through a complex query case study, and highlights the trade‑offs between accuracy, reasoning depth, and resource consumption.
