About This Tool

The tool converts a structured schema into MySQL CREATE statements. It targets developers, DBAs, data modelers, and deployment engineers who need repeatable DDL for new or evolving databases. Use cases include initial schema creation, versioned migrations, and dbt-style project generation.
Core logic maps inputs to MySQL dialect: tables, columns, data types, nullability, defaults, and constraints. Required features include table and column definitions, primary keys, not null, auto_increment, default values, and foreign keys. Optional features include indexes, unique constraints, and engine/charset options. Outputs are DDL scripts ready for execution.
The generator handles edge cases such as reserved keywords, identifier length, and version-specific syntax. It validates input completeness, detects missing primary keys or orphaned foreign keys, and flags conflicts. When external data references are unavailable, it emits placeholders or notes rather than failing silently.
Assumptions: The input describes a relational schema with clear table/column definitions. Exclusions: It does not generate data inserts, triggers, stored procedures, or non-MySQL dialects. It supports exporting to files or clipboard via the tool's output panel, enabling reproducible database builds. Use case examples: A data architect defines a 3-table schema with users, orders, and order_items; the tool outputs a MySQL script that creates users with proper indexing, a normalized orders table with foreign key to users, and an order_items table with composite primary key. It supports versioned outputs for migrations, with comments and optional constraint definitions to aid review and auditing.

How to Use

  1. Provide inputs: define tables, columns, data types, and constraints.
  2. Choose MySQL dialect version and optional features.
  3. Run generation to produce CREATE statements.
  4. Review and adjust generated SQL in the output panel.
  5. Copy or export to your project.

Frequently Asked Questions

Find Quick Answers

What does the tool generate?
It outputs MySQL CREATE statements for tables, columns, keys, and constraints based on the provided schema. It does not generate data inserts or triggers by default; you can extend the script manually for migrations.
Which MySQL versions are supported?
The generator targets common MySQL dialect features and aims to produce compatible DDL for MySQL 5.7 and 8.0. For newer features, you can adjust engine, charset, and constraint syntax in the output.
How are data types mapped?
The input specifies types which are mapped to MySQL equivalents. If a type is not directly available, the tool maps to the closest supported type and allows user-specified precision/scale in definitions.
Can I generate indexes and foreign keys?
Yes. The tool supports primary keys, foreign keys, unique constraints, and index declarations. It emits proper constraint syntax and resolves references when table names exist in the schema.
