mysql - MySQL 插入循环

Question

我想将一些行数据复制到另一个表中，例如：

我有这2 个表：( qa_items_purchases), ( qa_suppliers_invoices)

qa_items_purchases， 数据：

qa_suppliers_invoices是空的：

我需要复制表 (qa_items_purchases) 中包含的所有记录，仅提取另一个表具有的字段。

编辑： 在表格之间，名称会有所不同：

purchase_code AS itempurchase_code
supplier_invoice_code AS item_invoicecodesupplier
supploer_invoice_date as itempurchase_date

Answer 1

试试这个：

INSERT INTO qa_suppliers_invoices (purchase_code,supplier_code, user_code, status_code, supplier_invoice_code,supplier_invoice_date)

SELECT itempurchase_code,supplier_code, user_code, status_code,item_invoicecodesupplier,itempurchase_date FROM qa_items_purchases

Answer 2

插入选择手册，访问 http://dev.mysql.com/doc/refman/5.0/en/insert-select.html

insert into qa_suppliers_invoices 
(purchase_code, supplier_invoice_code, supploer_invoice_date )
SELECT itempurchase_code, item_invoicecodesupplier, itempurchase_date
FROM qa_items_purchases

如果您需要更多列，只需添加列。cols 顺序很重要。
