INSERT INTO table1 (table1_field1,table1_field2,...) select table2_filed1,table2_field2,... from table2 where condition1 and condition2 ...;
//一張表符合條件的資料插入另一張表對應欄位中
insert into shelve_goods_info(product_id,`name`,image,original_amount,amount,spec_id,spec_str,sync_time,last_updtime) select DISTINCT product_id,`name`,image,original_amount,amount,spec_id,spec_str,sync_time,NOW() from jingguo_order_goods group by product_id
order by sync_time desc;
//根據一張表的資料修改另一張表的資料
update shelve_goods_info as s,tt as t set s.print_title=t.newname, s.price=t.newprice, original_price=Ceil(t.newprice*10/8) where s.name=t.orname;
