# ORM Schema Generation

`OrmSchema` builds a `TableSpec` from annotated entities.

## Example

```java
import com.andrewkydev.database.orm.OrmSchema;
import com.andrewkydev.database.schema.SqlDialect;
import com.andrewkydev.database.schema.TableSpec;

TableSpec spec = OrmSchema.fromEntity(PlayerModel.class, SqlDialect.MYSQL);
api.schema().createTable(spec);
```

## Type Mapping

Default mapping (when `@DbColumn(type = "...")` is not specified):

- `String` -> `VARCHAR(length)`
- `int`/`Integer` -> `INT`
- `long`/`Long` -> `BIGINT`
- `short`/`Short` -> `SMALLINT`
- `boolean`/`Boolean` -> `BOOLEAN` (PostgreSQL) or `TINYINT(1)` (MySQL)
- `float`/`Float` -> `FLOAT`
- `double`/`Double` -> `DOUBLE`
- `UUID` -> `UUID` (PostgreSQL) or `CHAR(36)` (MySQL)
- `@DbJson` -> `JSON` (MySQL) or `JSONB` (PostgreSQL)

`@DbColumn(length, unique, nullable)` is also applied.
