mysql建表常用的sql語句匯總

最近跟項目，寫后臺需要用到SQL語句，就整理了一下mysql建表常用sql語句，并寫幾個可執行SQL腳本，方便日后復習查看以及使用：

連接：mysql -h主機地址 -u用戶名－p用戶密碼（注:u與root可以不用加空格，其它也一樣）

斷開：exit （回車）

創建授權：grant select on 數據庫.* to 用戶名@登錄主機 identified by \"密碼\"

修改密碼：mysqladmin -u用戶名 -p舊密碼 password 新密碼

刪除授權: revoke select,insert,update,delete om *.* from test2@localhost;

顯示數據庫：show databases;

顯示數據表：show tables;

顯示表結構：describe 表名;

創建庫：create database 庫名;

刪除庫：drop database 庫名;

使用庫(選中庫)：use 庫名;

創建表：create table 表名 (字段設定列表);

刪除表：drop table 表名;

修改表：alter table t1 rename t2

查詢表：select * from 表名;

清空表：delete from 表名;

備份表: mysqlbinmysqldump -h(ip) -uroot -p(password) databasename tablename > tablename.sql

恢復表: mysqlbinmysql -h(ip) -uroot -p(password) databasename tablename tablename.sql（操作前先把原來表刪除）

增加列：ALTER TABLE t2 ADD c INT UNSIGNED NOT NULL AUTO_INCREMENT,ADD INDEX (c);

修改列：ALTER TABLE t2 MODIFY a TINYINT NOT NULL, CHANGE b c CHAR(20);

刪除列：ALTER TABLE t2 DROP COLUMN c;

備份數據庫：mysql\bin\mysqldump -h(ip) -uroot -p(password) databasename > database.sql

恢復數據庫：mysql\bin\mysql -h(ip) -uroot -p(password) databasename database.sql

復制數據庫：mysql\bin\mysqldump --all-databases > all-databases.sql

修復數據庫：mysqlcheck -A -o -uroot -p54safer

文本數據導入： load data local infile \"文件名\" into table 表名;

數據導入導出：mysql\bin\mysqlimport database tables.txt

以下為MySQL的可執行腳本示例：

3.創建店鋪商品實例

//某電商平臺店鋪商品實例
 
create database store;          #創建數據庫store
use store;

drop table if exists goods;
create table goods

drop table if exists brand;
create table brand
