What The SQL Booklet is
The SQL Booklet is an independent editorial project. It organizes recurring SQL Server problems into concise references, applied cases, exploration queries, troubleshooting articles, and progressive paths. The public library currently contains 126 topics in English and their Spanish versions.
Each article reconstructs the need, explains the technical decision, shows the result, and defines the available conclusions.
Editorial responsibility
The SQL Booklet is responsible for selecting, writing, checking, translating, and maintaining the content published under this name. Technical sources are checked against primary documentation, and executable examples are tested in controlled environments when the article requires it.
SQL Server can choose different strategies depending on version, data, statistics, indexes, permissions, and configuration. Each article documents the relevant limits.

Scope and relationship with Microsoft
The SQL Booklet is not an official Microsoft site and is not affiliated with Microsoft. SQL Server, SQL Server Management Studio, and the names of their tools belong to their respective owners. Official documentation remains the primary reference for product behavior, compatibility, and support.
The content is intended for education and reference. Applying it requires reviewing the database, its backups, operational policies, and the authorizations for that environment.
