Instance Attribute Summary

• #description ⇒ String

  A string representation of the expression subtree rooted at this node.

• #subqueries ⇒ Hash{String => Integer}

  A mapping of (subquery variable name) -> (subquery node id) for cases where the +description+ string of this node references a +SCALAR+ subquery contained in the expression subtree rooted at this node.

Instance Attribute Details

#description ⇒ String

Returns A string representation of the expression subtree rooted at this node.

#subqueries ⇒ Hash{String => Integer}

Returns A mapping of (subquery variable name) -> (subquery node id) for cases where the +description+ string of this node references a +SCALAR+ subquery contained in the expression subtree rooted at this node. The referenced +SCALAR+ subquery may not necessarily be a direct child of this node.
