MySQL數據庫經常使用命令

MySQL鏈接

mysql -u root -p
Enter password:******

登陸成功後會顯示mysql>命令提示窗口

Welcome to the MySQL monitor....

mysql>

 登陸後建立數據庫

CREATE DATABASE  IF NOT EXISTS DatabaseName;

刪除數據庫

DROP DatabaseName;

選擇數據庫

use DatabaseName;

建立數據表

CREATE TABLE table_name (column_name column_type);

建立數據表例子

CREATE TABLE IF NOT EXISTS `test_tbl`(
   `test_id` INT UNSIGNED AUTO_INCREMENT,
   `test_title` VARCHAR(100) NOT NULL,
   `test_author` VARCHAR(40) NOT NULL,
   `submission_date` DATE,
   PRIMARY KEY ( `test_id` )
)ENGINE=InnoDB DEFAULT CHARSET=utf8;

刪除數據表

DROP TABLE table_name ;

 插入數據

INSERT INTO table_name ( field1, field2,...fieldN )
                       VALUES
                       ( value1, value2,...valueN );

查詢數據

SELECT column_name,column_name
FROM table_name
[WHERE Clause]
[OFFSET M ][LIMIT N]

使用where子句

SELECT field1, field2,...fieldN FROM table_name1, table_name2...
[WHERE condition1 [AND [OR]] condition2.....

讀取數據例子

SELECT * from test_tbl WHERE test_author='YoungNg';

導出SQL格式的數據例子

mysqldump -u root -p test test_tbl > dump.txt
password ******

 導入sql文件數據

mysql>source sqlFilePath;
