Built for MySQL

Every export is optimized for MySQL's specific syntax, types, and bulk loading commands.

LOAD DATA LOCAL INFILE

Generated exports include LOAD DATA LOCAL INFILE commands, MySQL's fastest bulk import method, loading CSV data directly into tables without per-row overhead.

Foreign Key Constraints

Full referential integrity with FOREIGN KEY constraints. All child table rows reference valid parent records, and tables are created in dependency order.

Standard MySQL DDL

Clean CREATE TABLE statements with INT, VARCHAR, DECIMAL, and DATETIME types. Standard syntax compatible with MySQL 5.7+ and 8.x.

CSV + SQL Export

Get both CREATE TABLE DDL and CSV data files paired with LOAD DATA commands. Import the full dataset with a single mysql client session.

Who uses MySQL test data?

Web App Developers

Seed LAMP/LEMP stack databases with realistic user, product, and transaction data for local development and staging environments.

WordPress & CMS Developers

Generate test content, user profiles, and metadata for WordPress plugins and custom CMS solutions built on MySQL.

SaaS Startups

Build and test multi-tenant schemas with realistic datasets before onboarding real customers. Validate query performance at scale.

Bulk Loading & FK Integrity

SynthForge IO generates MySQL exports optimized for fast imports with full referential integrity across all tables.

LOAD DATA Performance

LOAD DATA LOCAL INFILE bypasses the SQL parser for dramatically faster imports. It is the fastest way to load large CSV datasets into MySQL.

Referential Integrity

Every foreign key relationship is fully valid. Child rows always reference existing parent records, so constraints pass on import.

VARCHAR Mapping

String columns use VARCHAR with appropriate lengths. Text, email, name, and other field types map to standard MySQL string types.

Dependency-Ordered DDL

Tables are exported in correct dependency order so foreign key constraints resolve on first import. No need to disable checks.

Frequently asked questions

What MySQL versions does SynthForge IO support?

SynthForge IO generates standard SQL compatible with MySQL 5.7 and later, including MySQL 8.x. The DDL uses INT, VARCHAR, DECIMAL, and DATETIME. These types work across all modern MySQL versions.

Can I use LOAD DATA INFILE with the generated data?

Yes. MySQL SQL exports include LOAD DATA LOCAL INFILE commands paired with CSV data files. This is MySQL's fastest bulk import method, significantly faster than INSERT statements for datasets over a few thousand rows.

Does it support MySQL foreign key constraints?

Yes. SynthForge IO generates tables with FOREIGN KEY constraints and maintains full referential integrity. All child table rows reference valid parent records. Tables are created in dependency order so constraints resolve correctly.

What column types does SynthForge IO generate for MySQL?

SynthForge IO maps your schema fields to standard MySQL types: INT for integers, VARCHAR for strings, DECIMAL for precise numbers, DATETIME for timestamps, and TEXT for long content. All types are compatible across MySQL 5.7+ and 8.x.

How do I load the generated data into MySQL?

Download the SQL export and run it with mysql -u user -p database < export.sql. For large datasets, use the included LOAD DATA LOCAL INFILE commands with the CSV files. You can also import directly through MySQL Workbench or phpMyAdmin.
