MySQL

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.

Security

SQL injection vulnerabilities

String concatenation used to build queries instead of parameterized statements, allowing attackers to read, modify, or delete data.

Performance

Missing database indexes

Tables without indexes on columns used in WHERE, JOIN, and ORDER BY clauses, causing full table scans as data grows.

Performance

No connection pooling

Opening a new database connection per request instead of using a connection pool, exhausting MySQL's max_connections limit under load.

Security

Credentials in source code

Database host, username, and password hardcoded in application files or committed to version control.

Performance

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.

Deployment

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)

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.
