I found <i>Use the Index, Luke</i> interesting, but I don&#x27;t know much SQL. I wonder how this book compares.<p><a href="https:&#x2F;&#x2F;use-the-index-luke.com&#x2F;" rel="nofollow">https:&#x2F;&#x2F;use-the-index-luke.com&#x2F;</a>

I sort of have a beef with the usage of &quot;SQL performance&quot;. I know what people mean, but it still irks me.<p>SQL is a declarative query language. It describes the meaning of your query.<p>The execution of the query has performance implications based on the actual RDBMS and the semantics of the query, but you can&#x27;t improve the performance of your query without altering its meaning, only the performance of its execution.<p>It&#x27;s like when people describe the performance of Python when they mean the performance of the CPython runtime.
