Description

  • This PR fixes an issue where the query output columns were incorrectly not returning source columns for UPDATE statements with subqueries. For example:
UPDATE catalog.schema.test_table SET output_column = (SELECT test_column FROM catalog.schema.test_alt_table)

This query should set test_alt_table.test_column as a source column of test_table.output_column
