  38. def lookupVariable(nameParts: Seq[String]): Option[VariableReference]

    Look up variable by nameParts.

    Look up variable by nameParts. If in SQL Script, first check local variables, unless in EXECUTE IMMEDIATE (EXECUTE IMMEDIATE generated query cannot access local variables). if not found fall back to session variables.

    nameParts

    NameParts of the variable.

    returns

    Reference to the variable.

  44. def resolveColsLastResort(e: Expression): Expression

    The last resort to resolve columns.

    The last resort to resolve columns. Currently it does two things:

    • Try to resolve column names as outer references
    • Try to resolve column names as SQL variable

  45. def resolveExprInAssignment(expr: Expression, hostPlan: LogicalPlan): Expression
  46. def resolveExpressionByPlanChildren(e: Expression, q: LogicalPlan, includeLastResort: Boolean = false): Expression

    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.

  47. def resolveExpressionByPlanOutput(expr: Expression, plan: LogicalPlan, throws: Boolean = false, includeLastResort: Boolean = false): 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.

  48. 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.
