centos mysql 操作命令、指令合集
①创建数据库:
mysql> create database sqoop;
Query OK, 1 row affected (0.09 sec)
②显示数据库:
mysql> show databases;
+--------------------+
| Database |
+--------------------+
| information_schema |
| metastore |
| mysql |
| performance_schema |
| sqoop |
| sys |
+--------------------+
6 rows in set (0.02 sec)
③使用sqoop这个数据库
mysql> use sqoop;
Database changed
④mysql> create table studentsqoop ('id' int(4),'name' char(40));
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''id' int(4),'name' char(40))' at line 1
创这个表的时候出现了错误,解决办法:把单引号替换了问题就解决了。
⑤显示数据库中的表
mysql> show tables;
+-----------------+
| Tables_in_sqoop |
+-----------------+
| studentsqoop |
+-----------------+
1 row in set (0.02 sec)
⑥插入数据
mysql> insert into studentsqoop values (1007,'jiqiren');
Query OK, 1 row affected (0.00 sec)
