## SequelizeDataSource.execute() method

Execute a SQL command.

\*\*WARNING:\*\* In general, it is always better to perform database actions through repository methods. Directly executing SQL may lead to unexpected results, corrupted data, security vulnerabilities and other issues.

**Signature:**

```typescript
execute(command: Command, parameters?: NamedParameters | PositionalParameters, options?: Options): Promise<AnyObject>;
```

## Parameters

|  Parameter | Type | Description |
|  --- | --- | --- |
|  command | [Command](./repository.command.md) | A parameterized SQL command or query. |
|  parameters | [NamedParameters](./repository.namedparameters.md) \| [PositionalParameters](./repository.positionalparameters.md) | _(Optional)_ List of parameter values to use. |
|  options | [Options](./repository.options.md) | _(Optional)_ Additional options, for example <code>transaction</code>. |

**Returns:**

Promise&lt;[AnyObject](./repository.anyobject.md)<!-- -->&gt;

A promise which resolves to the command output. The output type (data structure) is database specific and often depends on the command executed.

## Example


```ts
// MySQL
const result = await db.execute(
  'SELECT * FROM Products WHERE size > ?',
  [42]
);

// PostgreSQL
const result = await db.execute(
  'SELECT * FROM Products WHERE size > $1',
  [42]
);
```
