### Column View

#### Filters

When looking at columns, you can do more granular work than the table view, but broader work than viewing an individual table. You can filter based on schema or table in the right sidebar, or find columns of a certain data type.

![Column View Filters](/files/Cq5ydwhqxdvn2HwGPMkX)

{% hint style="info" %}
Unknown column types are any column types not represented by the other filters. Unless you are using custom type fields, you should not expect to have any.
{% endhint %}

#### Join Field

The column-level view will have a filter for columns used to join to other tables.

![Column Join Field](/files/V3bC8fn1kqpboLdKHX14)

There will be a ![](/files/-Mi3R4pIjmPUAoTN1GY9) on some columns to indicate they are a join field, this is also visible on the table page.
