object EvaluateUnresolvedInlineTable extends SQLConfHelper with AliasHelper with EvalHelper with CastSupport
Utility object used to replace UnresolvedInlineTable with ResolvedInlineTable or (whenever possible) with LocalRelation. Typically, UnresolvedInlineTable is a child of InsertIntoStatement. Use the method: EvaluateUnresolvedInlineTable.evaluate as the entry point for this transformation.

- final def mergeAliases(alias: Alias): Alias
Merge an Alias(Alias(x)) into Alias(x) preserving metadata.
Merge an Alias(Alias(x)) into Alias(x) preserving metadata.
If the outer alias has explicit metadata, it is preserved. Else if the inner alias has explicit metadata, the result has explicit outer.metadata. Else both are deriving the metadata. the result is deriving metadata, with the union of noninheritable keys.
- alias
An Alias with a child Alias, Alias(Alias(x))
- returns
The merged alias, Alias(x)

Merge any stack of aliases under the top-level alias, and then drops any aliases deeper in the expression tree. So Alias1(Alias2(Alias3(Foo(Alias4(x))))) becomes Alias5(Foo(x)) where Alias5 preserves the metadata of Alias{1,2,3} and the name and exprId of Alias1. Alias4 is simply removed.

Validates that all inline table data are valid expressions that can be evaluated (in this they must be foldable). Note that nondeterministic expressions are not supported since they are not foldable. Exception are CURRENT_LIKE expressions, which are replaced by a literal in later stages. This is package visible for unit testing.
