进行了搜索但只能找到从一张桌子插入另一张桌子的东西。
我有这个查询从一个表中获取数据并将其插入到另一个表中:
INSERT INTO tbl_orders (product_id, customer_id)
SELECT product_id, customer_id FROM tbl_basket
WHERE customer_id = '" . $_SESSION['user'] . "'");
我想要做的是包含额外的数据。例如,我将根据另一个表插入product_id和customer_id,并插入不在另一个表中的额外值。
我试过这个没有运气:
INSERT INTO tbl_orders (product_id, customer_id, order_status)
SELECT product_id, customer_id, \'placed\' FROM tbl_basket
WHERE customer_id = '" . $_SESSION['user'] . "'"
有什么想法吗?谢谢。

如果要在表格中插入额外数据,可以尝试以下查询:
INSERT INTO tbl_orders (product_id, customer_id, order_status)
SELECT product_id, customer_id, 'order_status' FROM tbl_basket
WHERE customer_id = 'example'
如果第二个表中有额外的数据,您可以像这样加入第二个表:
INSERT INTO tbl_orders (product_id, customer_id, order_status)
SELECT product_id, customer_id, t2.order_status FROM tbl_basket t1
join tbl_basket2 t2 on t1.id = t2.id
WHERE t1.customer_id = 'example'
