**Use case**

ClickHouse already throws exception if the data for INSERT is empty:

```
Code: 108. DB::Exception: No data to insert
```

Let's introduce a setting, enabled by default, to control this behavior.
The user will be able to disable it to allow empty INSERTs.

This is useful in some batch scripts.
{
    return ParserColumnsMatcher().parse(pos, node, expected)
        || ParserQualifiedAsterisk().parse(pos, node, expected)
        || ParserAsterisk().parse(pos, node, expected)
        || ParserCompoundIdentifier().parse(pos, node, expected);
}
}
