This is quite a common question, and it is time to give it a simple, concise, and clear answer, once a...
In part 3 of our Azure SQL database change management (CICD) series we cover testing your code using tSQLt and GitHub Actions. Prerequisites Check Refer to part 1 and part 2 for the prerequisites. Fork the GitHub Project We will be using tSQLt in this post, so I have created a GitHub project made up of several SQL Da...
How to solve the common problem of "insert-if-not-exists" in a very elegant, clever and scalable way.
Graph theory and associated techniques are extremely powerful. Azure SQL allows native representation of graphs as node and edge tables, and provides breadth-first-search traversal for native path finding. This blog post demonstrates the ease of use, and great power of, these features by using them to solve the classic river crossing riddle!
Azure SQL developers have access to a full-fidelity, highly accurate, and easy-to-use client-side parser for T-SQL statements: the TransactSql.ScriptDom parser. This blog post walks through basic usage, and links to a number of resources for digging deeper.
Practical Azure SQL Database for Modern Developers: a book to learn how to take advantage of the all the breakthrough technologies available in Azure SQL like columnstore, in-memory lock-free tables, row-level-security, graph and geospatial support to create modern, scalable and secure applications.
There are many database technologies available on Azure that you can choose from. Why would you use Azure SQL? Let me show you why, using just 10 simple points: from JSON support to ColumnStore, through Geospatial and Temporal queries, Non-Blocking transaction, Encryption and Row-Level Security and the amazing Intelligent Query Optimizer.
