### Создание моделей

Импортируйте `SQLModel` и создайте модель базы данных:

{* ../../docs_src/sql_databases/tutorial001_an_py310.py ln[1:11] hl[7:11] *}

Класс `Hero` очень напоминает модель Pydantic (фактически, под капотом, *это и есть модель Pydantic*).

Но есть и некоторые различия

### Create Models { #create-models }

Import `SQLModel` and create a database model:

{* ../../docs_src/sql_databases/tutorial001_an_py310.py ln[1:11] hl[7:11] *}

The `Hero` class is very similar to a Pydantic model (in fact, underneath, it actually *is a Pydantic model*).

There are a few differences:

pkg debug/elf, const R_ARM_TLS_GD32 = 104
pkg debug/elf, const R_ARM_TLS_GD32 R_ARM
pkg debug/elf, const R_ARM_TLS_GOTDESC = 90
pkg debug/elf, const R_ARM_TLS_GOTDESC R_ARM
pkg debug/elf, const R_ARM_TLS_IE12GP = 111
pkg debug/elf, const R_ARM_TLS_IE12GP R_ARM
pkg debug/elf, const R_ARM_TLS_IE32 = 107
pkg debug/elf, const R_ARM_TLS_IE32 R_ARM
pkg debug/elf, const R_ARM_TLS_LDM32 = 105
pkg debug/elf, const R_ARM_TLS_LDM32 R_ARM

```java
if (!context.getConfig().isUseLeases() || !session.supports(SMB3_0)) {
    // Fall back to traditional oplock mechanism
    useOplockInstead();
}
```

### Crear Modelos

Importa `SQLModel` y crea un modelo de base de datos:

{* ../../docs_src/sql_databases/tutorial001_an_py310.py ln[1:11] hl[7:11] *}

La clase `Hero` es muy similar a un modelo de Pydantic (de hecho, en el fondo, realmente *es un modelo de Pydantic*).

Hay algunas diferencias:

        }
        
        // Wait for all reconnections
        CompletableFuture.allOf(futures.toArray(new CompletableFuture[0])).join();
    }
}
```
