ResolveDefaultColumns

case class ResolveDefaultColumns(resolveRelation: (UnresolvedRelation) ⇒ LogicalPlan) extends Rule[LogicalPlan] with Product with Serializable

This is a rule to process DEFAULT columns in statements such as CREATE/REPLACE TABLE.

Background: CREATE TABLE and ALTER TABLE invocations support setting column default values for later operations. Following INSERT, UPDATE, and MERGE commands may then reference the value using the DEFAULT keyword as needed.

Example: CREATE TABLE T(a INT DEFAULT 4, b INT NOT NULL DEFAULT 5); INSERT INTO T VALUES (1, 2); INSERT INTO T VALUES (1, DEFAULT); INSERT INTO T VALUES (DEFAULT, 6); SELECT * FROM T; (1, 2) (1, 5) (4, 6)

resolveRelation

function to resolve relations from the catalog. This should generally map to the 'resolveRelationOrTempView' method of the ResolveRelations rule.
