假设有一张表Student
-- 学生表
create table Student(
id Varchar2(11) primary key,
name varchar2(32) not null,
sex varchar2(3) not null,
age smallint,
tel varchar(16)
)
注意：其中[]中代表可选;<>代表必须;table_column的数量必须和column_value一致，并且数据类型要相匹配
1. 单条自定义记录插入
命令格式：
insert into table <tableName>[(<table_column1>,<table_column2>...)]
values([<column_value1>,<column_value2>...])
示例：insertinto Student(id, name, sex, age, tel) values (‘13’, ‘jack’, ‘男’, 13, ‘13345674567’)
2. 多条自定义记录插入
命令格式1：
insert all
into <tableName>[(<table_column1>,<table_column2>...)]
values([<column_value1>,<column_value2>...])
[into <tableName>[(<table_column1>,<table_column2>...)]
values([<column_value1>,<column_value2>...])]...
select <table_value1>[,<table_value2>...] from dual;
示例：
insert all into Student(id, name, sex, age, tel)
into Student(id, name, sex, age, tel) values ('12', 'jack1', '男', 12, '13345674567' )
into Student(id, name, sex, age, tel) values ('13', 'jack2', '男', 13, '13345674567')
select '14', 'jack', '男', 13, '13345674567' from dual;
注意: 我也不知道为什么要加select from dual语句，反正不加就报错
命令格式2：
insert into <tableName>[(<table_column1>,<table_column2>...)]
select [<column_value1>,<column_value2>...] from dual
[ union select [<column_value1>,<column_value2>...] from dual ]...
示例：
insert into student(id, name, sex, age, tel)
select '10' , 'ldh', '男', 19, '14445674567' from dual
union select '11' , 'zxy', '男', 20, '13333674567' from dual
union select '12', 'zxc', '男', 21, '15555674567' from dual
命令格式3：
insert into <tableName1>[(<table_column1>,<table_column2>...)]
select [<column_value1>,<column_value2>...] from <tableName2> [where [...]]
union [ select [<column_value1>,<column_value2>...] from <tableName2> [where [...] ]]
示例：
insert into student(id, name, sex, age, tel)
select (id-1)||'' as id, name, sex, age, tel from Student where id='11'
union select id||'1' as id, name, sex, age, tel from Student where id like '1%'
union select id||'2' as id, name, sex, age, tel from Student where id like '%1' and id/3 != 0
