如何在MySQL中正确使用INSERT INTO…SELECT以避免Error 1064？
让我们首先创建一个表-
mysql> create table DemoTable1 -> ( -> Id int NOT NULL AUTO_INCREMENT PRIMARY KEY, -> FirstName varchar(100) -> );
使用插入命令在表中插入一些记录-
mysql> insert into DemoTable1(FirstName) values('John');
mysql> insert into DemoTable1(FirstName) values('Chris');使用select语句显示表中的所有记录-
mysql> select *from DemoTable1;
这将产生以下输出-
+----+-----------+ | Id | FirstName | +----+-----------+ | 1 | John | | 2 | Chris | +----+-----------+ 2 rows in set (0.00 sec)
现在创建第二个表-
mysql> create table DemoTable2 -> ( -> CustomerId int, -> CustomerName varchar(100) -> );
现在您可以使用INSERTINTOSELECT命令在上表中插入一些记录-
mysql> insert into DemoTable2(CustomerId,CustomerName) -> select Id,FirstName from DemoTable1; Records: 2 Duplicates: 0 Warnings: 0
使用select语句显示表中的所有记录-
mysql> select *from DemoTable2;
这将产生以下输出-
+------------+--------------+ | CustomerId | CustomerName | +------------+--------------+ | 1 | John | | 2 | Chris | +------------+--------------+ 2 rows in set (0.00 sec)
