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

SQL index things I wish I knew earlier:
🔹 B-tree = sorted phone book
🔹 Clustered = table IS the index
🔹 5 indexes = 6 writes per INSERT
🔹 Low cardinality → planner skips it
🔹 Column order in composite = design decision
