case class SourceQuery(relation: SnowflakeRelation, refColumns: Seq[Attribute], alias: String) extends SnowflakeQuery with Product with Serializable

The query for a base type (representing a table or view).

relation

The base SnowflakeRelation representing the basic table, view, or subquery defined by the user.

refColumns

Columns used to override the output generation for the QueryHelper. These are the columns resolved by SnowflakeRelation.

alias

Query alias.
