SQL Query Review, Performance, and Relational Integrity Tools

SQL Query Review, Performance, and Relational Integrity Tools | Elysia Tools

Tool usage guide

Learn when to use this tool, what it supports, and how real users apply it.

Overview

This hub focuses on the SQL work that starts after you already have tables and need to make queries readable, safer, faster, and easier to verify. It keeps query formatting, visual query assembly, EXPLAIN-plan review, performance checks, injection screening, join testing, foreign-key validation, and schema-drift comparison in one place so engineers and analysts can move from draft SQL to more trustworthy production queries without bouncing across unrelated database pages.

When to use

Draft SQL usually needs formatting, join inspection, and performance review together before anyone trusts the result.
Query bugs often come from hidden schema drift or broken relationships, so keeping schema diff and foreign-key checks nearby makes troubleshooting faster.
Security and correctness reviews improve when teams can inspect injection patterns, explain plans, and relational assumptions in one repeatable workflow.

FAQ

How is this different from the database-schema-migration hub?

This hub is for query authoring, review, tuning, and integrity checks after a schema already exists. The migration hub is broader and focuses on shaping tables, planning DDL, and moving external data into database-ready structures.

Which tool should I start with when a query is slow?

Start with SQL Explain Plan Visualizer if you already have EXPLAIN output. If you only have raw SQL, use SQL Performance Analyzer first, then format the query to make rewrites and index decisions easier to review.

When do the samples help most in this hub?

Use the SQL script packs for formatting and review practice, the PostgreSQL advanced samples for optimization and EXPLAIN-style workflows, and the SQL injection samples when you want to test detection rules or teach safer query patterns.
