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INSERT INTO SELECT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)
