SQL Input
This free online MySQL to Go Structs generator turns your CREATE TABLE DDL statements into ready-to-use Go Structs instantly — with no server upload, no account, and no rate limits. Simply paste your MySQL schema on the left and the generated Go Structs code appears on the right in real time. All processing runs entirely in your browser using client-side JavaScript, keeping your database schema 100% private.
Code & Data Generator
Complete type mapping from MySQL SQL column types to Go Structs — including nullability, constraints, and gotchas.
| MySQL Type | Go Structs Type | Notes |
|---|---|---|
| INT AUTO_INCREMENT | int | `gorm:"primaryKey;autoIncrement"` |
| BIGINT AUTO_INCREMENT | int64 | `gorm:"primaryKey;autoIncrement"` |
| INT / INTEGER | int | — |
| BIGINT | int64 | — |
| TINYINT(1) | bool | — |
| FLOAT | float32 | — |
| DOUBLE | float64 | — |
| DECIMAL(p,s) | float64 | Use shopspring/decimal for exact arithmetic |
| VARCHAR(n) / TEXT | string | — |
| DATETIME | time.Time | import "time"; no timezone stored |
| TIMESTAMP | time.Time | UTC-stored; Go treats as UTC |
| DATE | time.Time | Time portion will be zero |
| JSON | json.RawMessage | import encoding/json; or typed struct |
| BLOB | []byte | — |
| ENUM | string | Or define typed string alias with constants |
| NULL column | *Type | Pointer type allows nil |
Everything you need to know about converting MySQL to Go Structs.
Paste your MySQL CREATE TABLE statements into the SQL editor on the left. The Go Structs output appears instantly on the right panel in real-time as you type.
Yes — completely. The entire conversion runs inside your browser using JavaScript. Your SQL is never sent to any server, logged, or stored anywhere. This makes it safe to use with production or confidential database schemas.
PostgreSQL, MySQL, SQLite, SQL Server, Oracle, and MariaDB DDL syntax are all supported. The parser auto-detects the dialect from your CREATE TABLE syntax automatically.
Yes! Paste multiple CREATE TABLE statements separated by semicolons and all tables will be converted simultaneously, including cross-table foreign key relationships.
Yes. NULL, NOT NULL, DEFAULT values, PRIMARY KEY, UNIQUE, and FOREIGN KEY constraints are all parsed and reflected in the Go Structs output. Nullable columns are correctly typed as optional properties or nullable types.
Yes, SchemaForge is completely free with no usage limits, no account required, and no rate limits. The tool runs entirely in your browser and will always be free.
