#sql_assertion ⇒ Google::Apis::DataplexV1::GoogleCloudDataplexV1DataQualityRuleSqlAssertion

A SQL statement that is evaluated to return rows that match an invalid state. If any rows are are returned, this rule fails.The SQL statement must use BigQuery standard SQL syntax, and must not contain any semicolons.You can use the data reference parameter $data() to reference the source table with all of its precondition filters applied. Examples of precondition filters include row filters, incremental data filters, and sampling.
