让我们首先创建一个表-
mysql> create table DemoTable ( UserId int, UserName varchar(20), UserAge int );
使用插入命令在表中插入一些记录-
mysql> insert into DemoTable(UserId,UserName,UserAge) values(100,'John',25),(101,'Larry',24),(102,'Chris',22),(103,'Carol',27); Records: 4 Duplicates: 0 Warnings: 0
使用select语句显示表中的所有记录-
mysql> select *from DemoTable;
这将产生以下输出-
+--------+----------+---------+ | UserId | UserName | UserAge | +--------+----------+---------+ | 100 | John | 25 | | 101 | Larry | 24 | | 102 | Chris | 22 | | 103 | Carol | 27 | +--------+----------+---------+ 4 rows in set (0.00 sec)
