+//
+// If an alias is provided, each column is prefixed with it. Otherwise the columns are returned as is.
+//
+// If a destination is provided, each column will be assigned to it. Otherwise there is no adjustment.
+//
+// Example - alias, no destination.
+// Input: ([id, name], "w")
+// Output: [w.id, w.name]
+//
+// Example - with alias, destination
+// Input: ([id, name], "w", "workflow")
+// Output: [w.id "workflow.id", w.name "workflow.name"]
