对于使用 SELECT 查询插入,语法如下 −
insert into yourTableName(yourColumnName1,yourColumnName2,yourColumnName3,...N) select yourValue1,yourValue2,yourValue3,......N;
首先我们创建一个表 −
mysql> create table DemoTable1603 -> ( -> StudentId int, -> StudentName varchar(20), -> StudentMarks int -> ); Query OK, 0 rows affected (0.50 sec)
使用 insert 命令在表中插入一些记录 −
mysql> insert into DemoTable1603(StudentId,StudentName,StudentMarks) select 101,'John',45; Query OK, 1 row affected (0.17 sec) Records: 1 Duplicates: 0 Warnings: 0 mysql> insert into DemoTable1603(StudentId,StudentName,StudentMarks) select 102,'Adam',76; Query OK, 1 row affected (0.11 sec) Records: 1 Duplicates: 0 Warnings: 0 mysql> insert into DemoTable1603(StudentId,StudentName,StudentMarks) select 103,'Bob',67; Query OK, 1 row affected (0.31 sec) Records: 1 Duplicates: 0 Warnings: 0
使用 select 语句显示表中的所有记录 −
mysql> select * from DemoTable1603;
这将产生以下输出 −
+-----------+-------------+--------------+ | StudentId | StudentName | StudentMarks | +-----------+-------------+--------------+ | 101 | John | 45 | | 102 | Adam | 76 | | 103 | Bob | 67 | +-----------+-------------+--------------+ 3 rows in set (0.00 sec)
