 这提供了用于计算要插入的行的SQL查询机制（ http://www.postgresql.org/docs/17/queries.html[第 7 章]）的全部功能。

 It is also possible to insert the result of a query (which might be no rows, one row, or many rows):
 
 ```
 INSERT INTO products (product_no, name, price)
   SELECT product_no, name, price FROM new_products
-    WHERE release_date = 'today';
+    WHERE release_date = '2025-05-29';
 ```
 
 This provides the full power of the SQL query mechanism for computing the rows to be inserted.
