Expert MySQL Code Review for AI-Built Apps
MySQL is one of the most widely used relational databases. AI tools often generate MySQL queries with injection vulnerabilities, missing indexes, and no connection management — issues that become critical under real traffic.
Common MySQL issues we find
Real problems from MySQL codebases we've reviewed.
SQL injection vulnerabilities
String concatenation used to build queries instead of parameterized statements, allowing attackers to read, modify, or delete data.
Missing database indexes
Tables without indexes on columns used in WHERE, JOIN, and ORDER BY clauses, causing full table scans as data grows.
No connection pooling
Opening a new database connection per request instead of using a connection pool, exhausting MySQL's max_connections limit under load.
Credentials in source code
Database host, username, and password hardcoded in application files or committed to version control.
N+1 query patterns
Fetching a list of records, then querying related data one record at a time in a loop, causing hundreds of unnecessary queries.
Missing migration workflow
Schema changes applied directly to the production database without migration files, making rollbacks impossible.
MySQL production checklist
Key checks before deploying your MySQL app.
All queries use parameterized statements (no string concatenation)
Database credentials stored in environment variables
Connection pooling configured with appropriate pool size
Indexes on all columns used in WHERE, JOIN, and ORDER BY
Migration files for all schema changes
User privileges follow least-privilege principle
Automated backups configured and tested
Slow query logging enabled for monitoring

Frequently asked questions
Is my MySQL setup secure?
AI-generated MySQL code almost always uses string concatenation for queries, which is the #1 cause of SQL injection — ranked A03 on the OWASP Top 10. We audit every query, enforce parameterized statements, and lock down access controls.
Should I use MySQL or PostgreSQL?
Both are excellent. MySQL is simpler to get started with and has great hosting options (PlanetScale, AWS RDS). PostgreSQL has more advanced features like JSONB and better extensibility. We help with either.
How do I optimize my MySQL queries?
We run EXPLAIN on your slow queries, add missing indexes, eliminate N+1 patterns, configure connection pooling, and implement query caching where appropriate.
