在MySQL中插入Select查询

2024-05-17 07:29:05 426

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 |
+-----------+-------------+--------------+
