Dataplex automatic data quality supports the following capabilities

## Feature Dataplex automatic data quality supports the following capabilities: * The [SQL assertion rule type](https://cloud.google.com/dataplex/docs/auto-data-quality-overview#supported-custom-sql-rule-types) for custom SQL rules lets you check for an invalid state of a dataset. * You can use the [data reference parameter](https://cloud.google.com/dataplex/docs/auto-data-quality-overview#data-reference-parameter) in a custom SQL rule to refer to a data source table and all of its precondition filters, instead of explicitly mentioning the table and its filters.
