#ignore_null ⇒ Boolean Also known as: ignore_null?

Optional. Rows with null values will automatically fail a rule, unless ignore_null is true. In that case, such null rows are trivially considered passing.This field is only valid for the following type of rules: RangeExpectation RegexExpectation SetExpectation UniquenessExpectation Corresponds to the JSON property ignoreNull

Returns:

  • (Boolean)

#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. For more information, see Data reference parameter (https://cloud.google.com/dataplex/docs/auto-data- quality-overview#data-reference-parameter).Example: SELECT * FROM $data() WHERE price < 0 Corresponds to the JSON property sqlAssertion
