```ts
const result = await repository.execute('SELECT * FROM Products');
```
## Examples

### MySQL

Use parameterized queries to avoid SQL injection attacks.

```ts
const result = await repository.execute(
'SELECT * FROM Products WHERE id = ?',
[productId]
);
```

### PostgreSQL

```ts
const result = await repository.execute(
'SELECT * FROM Products WHERE id = $1',
[productId]
);
```

### MongoDB

```ts
const result = await repository.execute(
'MyCollection',
'aggregate',
[
{$unwind: '$data'},
{$out: 'tempData'},
]
);
```

Use parameterized queries whenever possible instead of constructing SQL strings manually.

See API docs for parameter reference, additional information and examples:
