ResolveReferencesInAggregate

class ResolveReferencesInAggregate extends SQLConfHelper with ColumnResolutionHelper with AliasHelper

A virtual rule to resolve UnresolvedAttribute in Aggregate. It's only used by the real rule ResolveReferences. The column resolution order for Aggregate is: 1. Resolves the columns to AttributeReference with the output of the child plan. This includes metadata columns as well. 2. Resolves the columns to a literal function which is allowed to be invoked without braces, e.g. SELECT col, current_date FROM t. 3. If aggregate expressions are all resolved, resolve GROUP BY alias and GROUP BY ALL. 3.1. If the grouping expressions contain an unresolved column whose name matches an alias in the SELECT list, resolves that unresolved column to the alias. This is to support SQL pattern like SELECT a + b AS c, max(col) FROM t GROUP BY c. 3.2. If the grouping expressions only have one single unresolved column named 'ALL', expanded it to include all non-aggregate columns in the SELECT list. This is to support SQL pattern like SELECT col1, col2, agg_expr(...) FROM t GROUP BY ALL. 4. Resolves the columns in aggregate expressions to LateralColumnAliasReference if it references the alias defined previously in the SELECT list. The rule ResolveLateralColumnAliasReference will further resolve LateralColumnAliasReference and rewrite the plan. This is to support SQL pattern like SELECT col1 + 1 AS x, x + 1 AS y, y + 1 AS z FROM t. 5. Resolves the columns to outer references with the outer plan if we are resolving subquery expressions.

  45. 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

    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.

    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.
