SQL Input
This free online SQLite to C# POCO generator turns your CREATE TABLE DDL statements into ready-to-use C# POCO instantly — with no server upload, no account, and no rate limits. Simply paste your SQLite schema on the left and the generated C# POCO 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 C# POCO — including nullability, constraints, and gotchas.
| SQLite Type | C# POCO Type | Notes |
|---|---|---|
| INTEGER PRIMARY KEY | long | [Key] SQLite rowid; 64-bit signed integer |
| INTEGER | long | SQLite INTEGER is always 64-bit |
| REAL | double | 8-byte float |
| TEXT | string | — |
| BLOB | byte[] | — |
| BOOLEAN (INTEGER 0/1) | bool | Microsoft.Data.Sqlite maps automatically |
| DATE / DATETIME (TEXT) | DateTime | SQLite stores as ISO text; parsed by driver |
| NULL column | Type? Field | Nullable; any SQLite column can be NULL |
Everything you need to know about converting SQLite to C# POCO.
Paste your SQLite CREATE TABLE statements into the SQL editor on the left. The C# POCO 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 C# POCO 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.
