ResolveColumnDefaultInInsert

object ResolveColumnDefaultInInsert extends SQLConfHelper with ColumnResolutionHelper with Product with Serializable

A virtual rule to resolve column "DEFAULT" in Project and UnresolvedInlineTable under InsertIntoStatement. It's only used by the real rule ResolveReferences.

This virtual rule is triggered if: 1. The column "DEFAULT" can't be resolved normally by ResolveReferences. This is guaranteed as ResolveReferences resolves the query plan bottom up. This means that when we reach here to resolve InsertIntoStatement, its child plans have already been resolved by ResolveReferences. 2. The plan nodes between Project and InsertIntoStatement are all unary nodes that inherit the output columns from its child. 3. The plan nodes between UnresolvedInlineTable and InsertIntoStatement are either Project, or Aggregate, or SubqueryAlias.

    Resolves UnresolvedAttribute, GetColumnByOrdinal and extract value expressions(s) by the input plan's children output attributes.

    Resolves UnresolvedAttribute, GetColumnByOrdinal and extract value expressions(s) by the input plan's children output attributes.

    e

    The expression need to be resolved.

    q

    The LogicalPlan whose children are used to resolve expression's attribute.

    returns

    resolved Expression.

    Resolves UnresolvedAttribute, GetColumnByOrdinal and extract value expressions(s) by the input plan's output attributes.

    Resolves UnresolvedAttribute, GetColumnByOrdinal and extract value expressions(s) by the input plan's output attributes. In order to resolve the nested fields correctly, this function makes use of throws parameter to control when to raise an AnalysisException.

    Example : SELECT * FROM t ORDER BY a.b

    In the above example, after a is resolved to a struct-type column, we may fail to resolve b if there is no such nested field named "b". We should not fail and wait for other rules to resolve it if possible.

  38. def resolveExprsAndAddMissingAttrs(exprs: Seq[Expression], plan: LogicalPlan): (Seq[Expression], LogicalPlan)

    This method tries to resolve expressions and find missing attributes recursively.

    This method tries to resolve expressions and find missing attributes recursively. Specifically, when the expressions used in Sort or Filter contain unresolved attributes or resolved attributes which are missing from child output. This method tries to find the missing attributes and add them into the projection.
