1+N querys Widely know as N+plus one problem, it’s actually a misnomer. As @adamj.eu’s article neatly summarize with examples (and now my dyslexic mind actually understands it), it’s one query to get a list of N objects that you iterate over. And each iteration...

Boosting RAG search relevance often starts with query optimization. Generating synthetic queries and re-writing user inputs are powerful techniques to significantly enhance result accuracy. Don't underestimate the input! 💡 #QueryOptimization 2/5

Avoid non-sargable queries! Applying functions to indexed columns forces full table scans, killing performance. Instead, use indexed computed columns or case-insensitive collations for efficient filtering. #QueryOptimization 4/6
