在MySQL中插入Select查询
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;
让我们首先创建一个表-
mysql> create table DemoTable1603-> (
-> StudentId int,
-> StudentName varchar(20),
-> StudentMarks int
-> );
使用插入命令在表中插入一些记录-
mysql> insert into DemoTable1603(StudentId,StudentName,StudentMarks) select 101,'John',45;Records: 1 Duplicates: 0 Warnings: 0
mysql> insert into DemoTable1603(StudentId,StudentName,StudentMarks) select 102,'Adam',76;
Records: 1 Duplicates: 0 Warnings: 0
mysql> insert into DemoTable1603(StudentId,StudentName,StudentMarks) select 103,'Bob',67;
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 |
+-----------+-------------+--------------+
