As we mentioned above, the second way you can create a sandbox is by using a saved question to define a customized view of a table to display. When a user with sandboxed access to a table queries that table, behind the scenes they'll really be using that saved question as the source data for their query.

**Note:** this filtering will also happen when a user with sandboxed access goes to look at a chart that uses data from the sandboxed table. If the chart uses any columns that aren't included in the sandboxed version of the table, the chart will not load for that user.
#### Example 2: using variables in a saved question
To create even more powerful and nuanced filters, you can use variables in a filtering question in conjunction with user attributes.
In this example, I'm going to give users in a specific group access to my `Orders` table, but I'll filter out which columns they can see, and I'll also make it so that they only see rows where the "Customer ID" column equals the user's `customer_id` attribute.

A field filter variable inserts SQL similar to that generated by the GUI query builder when adding filters on existing columns. This is useful because it lets you do things like insert dynamic date range filters into your native query. When adding a field filter, you should link that variable to a specific column. Field filter variables should be used inside of a `WHERE` clause in SQL, or a `$match` clause in MongoDB.
**Note:**
- Table aliases are not supported. This is because field filters generate SQL based on the mapped field.
- Some databases require the schema in the `FROM` clause. An example for Oracle would be `FROM "schema"."table"`. In BigQuery, back ticks are needed, like `` FROM `dataset_name.table` ``.
