Support Lambda Argument in APPLY Column Transformer for Multi-Argument Functions
Support lambda argument for APPLY column transformer which allows applying functions with more than one argument. This is for #27877. #27901 (Amos Bird).Why it matters
This feature enhances the<code>APPLY</code> column transformer by allowing users to apply functions that accept more than one argument. It solves the limitation of applying only single-argument functions, providing greater flexibility and expressiveness in column transformations.How to use it
Users can now define lambda functions with multiple parameters within the<code>APPLY</code> transformer to transform columns. For example, using <code>APPLY</code> with a lambda taking two or more arguments to perform complex operations on columns.
