relational-query-and-change-planning

Designs relational schemas and SQL reads or changes using joins, aggregation, subqueries, bound parameters, transactions, indexes, and execution plans. Use when the user asks to "write a query", "fix a slow SQL query", "design a table schema", "join two tables", or works in .sql files. Not for non-relational stores such as MongoDB, ORM model code unrelated to SQL, or running unapproved changes against production data.
