Ok so just to be clear would you have this
```python
        if sql_query is None:
            self.sql_query = """SELECT %s FROM %s WHERE %s""" % (
                sql_select, sql_from, sql_where
                )
```
or this
```python
        if sql_query is None:
            self.sql_query = """SELECT %s FROM %s WHERE %s""" % (
                sql_select, sql_from, sql_where
            )
```
