+// VALUES is a table value constructor that computes a set of one or more rows as a temporary constant table.
+// Each row is defined by the ROW constructor, which takes one or more expressions.
+//
+// Example usage:
+//
+//	VALUES(
+//		ROW(Int32(204), Float32(1.21)),
+//		ROW(Int32(207), Float32(1.02)),
+//	)
+func VALUES(rows ...RowExpression) values {
+	return values{Values: jet.Values(rows)}
+}
+
+// AS assigns an alias to the temporary VALUES table, allowing it to be referenced
+// within SQL FROM clauses, just like a regular table.
+// By default, VALUES columns are named `column1`, `column2`, etc... Default column aliasing can be
+// overwritten by passing new list of columns.
+//
+// Example usage:
+//
+//	VALUES(...).AS("film_values", IntegerColumn("length"), TimestampColumn("update_date"))
