### 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*.

from sqlalchemy import StaticPool
from sqlmodel import SQLModel, create_engine
from sqlmodel.main import default_registry

from tests.utils import needs_py310


def clear_sqlmodel():
    # Clear the tables in the metadata for the default base model
    SQLModel.metadata.clear()
    # Clear the Models associated with the registry, to avoid warnings
    default_registry.dispose()


@pytest.fixture(
    name="client",

import com.google.common.collect.SortedMapDifference;
import com.google.common.collect.SortedMultiset;
import com.google.common.collect.SortedSetMultimap;
import com.google.common.collect.Table;
import com.google.common.collect.Tables;
import com.google.common.collect.TreeBasedTable;

### Die Tabellen erstellen { #create-the-tables }

Dann fügen wir eine Funktion hinzu, die `SQLModel.metadata.create_all(engine)` verwendet, um die **Tabellen für alle *Tabellenmodelle* zu erstellen**.

  /** Default size of a compact hash-based collection. */
  static final int DEFAULT_SIZE = 3;

  /**
   * Minimum size of the hash table of a compact hash-based collection. Because small hash tables
   * use a byte[], any smaller size uses the same amount of memory due to object padding.
   */
  private static final int MIN_HASH_TABLE_SIZE = 4;

  private static final int BYTE_MAX_SIZE = 1 << Byte.SIZE; // 2^8 = 256

Не волнуйтесь, с такой структурой кода мы позже обеспечим использование **одной *сессии* SQLModel на запрос**, по сути именно этого и добивается `check_same_thread`.

### 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] *}

  /** Default size of a compact hash-based collection. */
  static final int DEFAULT_SIZE = 3;

  /**
   * Minimum size of the hash table of a compact hash-based collection. Because small hash tables
   * use a byte[], any smaller size uses the same amount of memory due to object padding.
   */
  private static final int MIN_HASH_TABLE_SIZE = 4;

  private static final int BYTE_MAX_SIZE = 1 << Byte.SIZE; // 2^8 = 256

				}

				return nil
			}); err != nil {
				return err
			}
		}
	}

	return nil
}

// GetTables returns tables
func (m Migrator) GetTables() (tableList []string, err error) {
	err = m.DB.Raw("SELECT TABLE_NAME FROM information_schema.tables where TABLE_SCHEMA=?", m.CurrentDatabase()).
		Scan(&tableList).Error
	return
}

// CreateTable create table in database for values

### 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] *}
