下列是张基础表(本人用的是Webyog SQLyog软件 )
CREATE TABLE fop
(
fopId INT PRIMARY KEY AUTO_INCREMENT,
fopName VARCHAR(20),
exe VARCHAR(20),
mop VARCHAR(20),
STATUS INT
)
INSERT INTO fop(fopName,exe,mop,STATUS) VALUES ('晓晓','男','跑',1),('看你晓','男','跑',1),('动漫晓','男','跑',1),('放假晓','男','跑',1);
“查询整个表”
SELECT * FROM fop
***下划线的需要添加表名***
下列是执行语句------
“查询一列”
SELECT exe FROM fop
“查询多列”
SELECT exe ,mop FROM fop
“插入一行”
INSERT INTO fop(fopName,exe,mop,STATUS) VALUES ('苗苗','女','走',1)
“插入多行”
INSERT INTO fop(fopName,exe,mop,STATUS) VALUES ('康康','女','走',1),('炎炎','女','走',1)
“更新数据库中的数据”
UPDATE fop
SET mop='飞', STATUS='10' ,exe='女'
WHERE fopName='动漫晓';
“删除表”
DROP TABLE
“删除一行”
DELETE FROM fop WHERE fopname='苗苗' AND STATUS='1';
“删除所有行,保留表”
DELETE * FROM fopname
“新建数据库”“数据库里包含表,多个表”
CREATE DATABASE
“新建表”
CREATE TABLE
SELECT * FROM fop
“添加列”
ALTER TABLE fop
ADD kop DATE
“删除列”
ALTER TABLE fop
DROP COLUMN kop
