This free online SQLite to Java Entities generator turns your CREATE TABLE DDL statements into ready-to-use Java Entities instantly — with no server upload, no account, and no rate limits. Simply paste your SQLite schema on the left and the generated Java Entities 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 SQLite SQL column types to Java Entities — including nullability, constraints, and gotchas.
| SQLite Type | Java Entities Type | Notes |
|---|---|---|
| INTEGER PRIMARY KEY | Long | @Id; SQLite rowid is 64-bit |
| INTEGER | Long | SQLite INTEGER is always int64 |
| REAL | Double | — |
| TEXT | String | — |
| BLOB | byte[] | @Lob |
| BOOLEAN (0/1) | Boolean | @Column(columnDefinition="INTEGER") |
| DATE / DATETIME (TEXT) | LocalDateTime | Use @Convert with custom AttributeConverter |
| NULL column | Type field | @Column(nullable=true) |
Everything you need to know about converting SQLite to Java Entities.
Paste your SQLite CREATE TABLE statements into the SQL editor on the left. The Java Entities 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 Java Entities 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.
