Question

我想将以下语句中的结果数据作为现有表中的新行插入：

SELECT a.post_date, b.vendor_name, c.lastName, d.firstName, null as taxiGroup
FROM (select ID,post_date from wp_posts where post_type = 'shop_order') as a, 
(SELECT order_id,vendor_name FROM wp_wcpv_commissions) as b,
(SELECT post_id,meta_value as lastName  FROM wp_postmeta  where  meta_key ='_billing_last_name') as c, 
(SELECT post_id,meta_value as firstName FROM wp_postmeta WHERE  meta_key ='_billing_first_name') as d
WHERE a.ID = b.order_id and b.order_id=c.post_id and c.post_id = d.post_id;

但是，如果我使用INSERT INTO taxipassengers () VALUES(<the query above>);形式，我会得到You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 6，无论那是什么意思。

建议？

编辑：乍一看，这是一个双引号，但在我复制/粘贴之后，我看到它是两个连续的单引号，这是仍然很好奇，但至少更有意义，因为我在查询中的任何地方都没有双引号。

Answer 1

正确的语法是：

insert into taxipassengers
select ...

所以，有is no values() clause。

Answer 2

试试这个，对于别名我们不需要“as”

SELECT a.post_date, b.vendor_name, c.lastName, d.firstName, null as taxiGroup
    FROM (select ID,post_date from wp_posts where post_type = 'shop_order') a, 
    (SELECT order_id,vendor_name FROM wp_wcpv_commissions)  b,
    (SELECT post_id,meta_value as lastName  FROM wp_postmeta  where  meta_key ='_billing_last_name') c, 
    (SELECT post_id,meta_value as firstName FROM wp_postmeta WHERE  meta_key ='_billing_first_name') d
    WHERE a.ID = b.order_id and b.order_id=c.post_id and c.post_id = d.post_id;

从几个表中抓取数据并插入新表
