### Criar as Tabelas { #create-the-tables }

Em seguida, adicionamos uma função que usa `SQLModel.metadata.create_all(engine)` para **criar as tabelas** para todos os *modelos de tabela*.

{* ../../docs_src/sql_databases/tutorial001_an_py310.py ln[21:22] hl[21:22] *}

### Criar uma Dependência de Sessão { #create-a-session-dependency }

### Создание таблиц { #create-the-tables }

Далее мы добавим функцию, которая использует `SQLModel.metadata.create_all(engine)`, чтобы **создать таблицы** для всех *моделей-таблиц*.

{* ../../docs_src/sql_databases/tutorial001_an_py310.py ln[21:22] hl[21:22] *}

### Создание зависимости Session { #create-a-session-dependency }

### Crear las Tablas { #create-the-tables }

Luego añadimos una función que usa `SQLModel.metadata.create_all(engine)` para **crear las tablas** para todos los *modelos de tabla*.

{* ../../docs_src/sql_databases/tutorial001_an_py310.py ln[21:22] hl[21:22] *}

### Crear una Dependencia de Session { #create-a-session-dependency }

### Create the Tables { #create-the-tables }

We then add a function that uses `SQLModel.metadata.create_all(engine)` to **create the tables** for all the *table models*.

{* ../../docs_src/sql_databases/tutorial001_an_py310.py ln[21:22] hl[21:22] *}
