MySQL Advanced SQL

Use When

• Advanced MySQL 8 SQL techniques: window functions, CTEs, recursive queries, pivoting, JSON operations, stored procedures, triggers, and complex aggregations. Use when writing analytical queries, transforming data, implementing reporting SQL...
• The task needs reusable judgment, domain constraints, or a proven workflow rather than ad hoc advice.

Do Not Use When

• The task is unrelated to mysql-advanced-sql or would be better handled by a more specific companion skill.
• The request only needs a trivial answer and none of this skill's constraints or references materially help.

Required Inputs

• Gather relevant project context, constraints, and the concrete problem to solve; load references only as needed.
• Confirm the desired deliverable: design, code, review, migration plan, audit, or documentation.
