테이블을 만들어 봅시다 -
mysql> create table DemoTable1923 ( UserId int NOT NULL AUTO_INCREMENT PRIMARY KEY, UserName varchar(20) ); Query OK, 0 rows affected (0.00 sec)
삽입 명령을 사용하여 테이블에 일부 레코드 삽입 -
mysql> insert into DemoTable1923(UserId,UserName) select 101 as UserId,'Chris' as UserName; Query OK, 1 row affected (0.00 sec) Records: 1 Duplicates: 0 Warnings: 0 mysql> insert into DemoTable1923(UserId,UserName) select 102 as UserId,'Robert' as UserName; Query OK, 1 row affected (0.00 sec) Records: 1 Duplicates: 0 Warnings: 0 mysql> insert into DemoTable1923(UserId,UserName) select 103 as UserId,'Sam' as UserName; Query OK, 1 row affected (0.00 sec) Records: 1 Duplicates: 0 Warnings: 0
select 문을 사용하여 테이블의 모든 레코드 표시 -
mysql> select * from DemoTable1923;
이것은 다음과 같은 출력을 생성합니다 -
+--------+----------+ | UserId | UserName | +--------+----------+ | 101 | Chris | | 102 | Robert | | 103 | Sam | +--------+----------+ 3 rows in set (0.00 sec)
