如何在mysql中将数据从表传输到表

Question

我想将数据从一个表传输到另一个表，我还想在第二个表中添加一个额外的列。

INSERT INTO invoiceitem(invoiceno, barcode, itemname, quantity, unitprice, subamount)
VALUES
    ('$Succ2', SELECT barcode, resultname, quantity, resultprice, subamount)
FROM test;

Answer 1

如果要使用查询的结果集插入，则语法为INSERT INTO ... SELECT，即在这种情况下我们不使用VALUES。可以向SELECT语句添加文字值，例如试试这个：

INSERT INTO invoiceitem (invoiceno, barcode, itemname, quantity, unitprice, subamount)
SELECT '$Succ2', barcode, resultname, quantity, resultprice, subamount
FROM test; 

Answer 2

正确的语法是：

INSERT INTO invoiceitem(invoiceno,barcode,itemname,quantity,unitprice,subamount)
SELECT '$Succ2' ,barcode,resultname,quantity,resultprice,subamount FROM test;

Answer 3

如果要将值从一个表插入另一个表，则无需在插入查询中使用VALUES。请参考INSERT TABLE TO ANOTHER TABLE

INSERT INTO invoiceitem (invoiceno, barcode, itemname, quantity, unitprice, subamount)
SELECT '$Succ2' barcode, resultname, quantity, resultprice, subamount
FROM test;
