1、创建表格并指定结构

CREATE TABLE DB3.STUINFO(
STUID INT,
STUNAME VARCHAR(10),
SEX INT,
AGE INT,
CLASSNO VARCHAR(10),
STUADDRESS VARCHAR(10),
GRADE INT,
ENROLDATE DATE,
IDNUMBER VARCHAR(20));

2、插入数据

规范用法

INSERT INTO table(col1,col2...) VALUES(value1, value2...)

如：

INSERT INTO DB3.STUINFO (STUID, STUNAME, SEX, AGE, CLASSNO, STUADDRESS, GRADE, ENROLDATE, IDNUMBER)
values ('1', '龙七', '1', 26, 'C201801', '厦门市', '2018', to_date('01-09-2018', 'dd-mm-yyyy'),'3503021992XXXXXXXX');

可以发现数字即便加上引号，Oracle也能智能识别。

当前后一一对应时也可省略table后的列名声明：

INSERT into DB3.STUINFO 
values (2, '龙八', 1, 25, 'C201801', '厦门市', '2018', to_date('01-09-2018', 'dd-mm-yyyy'), '3503021993XXXXXXXX');

省略列名声明的情况下，前后类型不对应或缺失信息时将报错。

指定列名时，未指定值的列默认填充为null：

INSERT into DB3.STUINFO (STUID, STUNAME, SEX, AGE, STUADDRESS, GRADE, ENROLDATE, IDNUMBER)
values (2, '龙八', 1, 25, '厦门市', '2018', to_date('01-09-2018', 'dd-mm-yyyy'), '3503021993XXXXXXXX');

也可在创建表结构的同时为列指定默认值，当无对应输入时自动填充：

CREATE TABLE a (
id INT,
name CHAR(10) default 'a',
class INT NOT NULL
);

INSERT INTO a
VALUES (1,NULL,1);INSERT INTO a (id,class)
VALUES (1,1);

可得到：

3、可与子查询合用

INSERT INTO a(id,class)
VALUES ((SELECT STUID FROM STUINFO WHERE STUNAME='龙七'),2);

STUINFO构建总命令：

CREATE TABLE DB3.STUINFO(
STUID INT,
STUNAME VARCHAR(10),
SEX INT,
AGE INT,
CLASSNO VARCHAR(10),
STUADDRESS VARCHAR(10),
GRADE INT,
ENROLDATE DATE,
IDNUMBER VARCHAR(20));INSERT into DB3.STUINFO (STUID, STUNAME, SEX, AGE, CLASSNO, STUADDRESS, GRADE, ENROLDATE, IDNUMBER)
values ('1', '龙七', '1', 26, 'C201801', '厦门市', '2018', to_date('01-09-2018', 'dd-mm-yyyy'),'3503021992XXXXXXXX');INSERT into DB3.STUINFO 
values (2, '龙八', 1, 25, 'C201801', '厦门市', '2018', to_date('01-09-2018', 'dd-mm-yyyy'), '3503021993XXXXXXXX');INSERT into DB3.STUINFO (STUID, STUNAME, SEX, AGE, STUADDRESS, GRADE, ENROLDATE, IDNUMBER)
values (2, '龙八', 1, 25, '厦门市', '2018', to_date('01-09-2018', 'dd-mm-yyyy'), '3503021993XXXXXXXX');INSERT into DB3.STUINFO (STUID, STUNAME, SEX, AGE, STUADDRESS, GRADE, ENROLDATE, IDNUMBER)
values (3, '龙九', 2, 23, '三门市', '2017', to_date('01-09-2017', 'dd-mm-yyyy'), '3503041995XXXXXXXX');INSERT into DB3.STUINFO (STUID, STUNAME, SEX, AGE,CLASSNO, STUADDRESS, GRADE, ENROLDATE, IDNUMBER)
values (3, '龙九', 2, 23, 'C201702', '三门市', '2017', to_date('01-09-2017', 'dd-mm-yyyy'), '3503041995XXXXXXXX');INSERT into DB3.STUINFO (STUID, STUNAME, SEX, AGE,CLASSNO, STUADDRESS, GRADE, ENROLDATE, IDNUMBER)
values (4, '龙十', 2, 23, 'C201702', '三门市', '2017', to_date('01-09-2017', 'dd-mm-yyyy'), '3503041995XXXXXXXX');
