ORACLE 批量插入(Insert)详解

Oracle批量插入语句与其他数据库不同，下面列出不同业务需求的插入

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
