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 | +-----------+-------------+--------------+ 3 rows in set (0.00 sec)
