有一个需求：将一个含多个clob的表，分别插入到两个表中（一个是不含clob的表，一个是含clob的表）。insert all此时派上用场了。
create table test
id number,
col1 number,
col2 number,
col3 number,
col4 number
);
create table test1
(
id number,
col1 number,
col2 number
);
create table test2
(
id number,
col3 number
);
insert into test values(1,1,1,1,1);
insert into test values(2,2,2,2,2);
insert into test values(3,3,3,3,3);
insert into test values(4,4,4,4,4);
commit;
insert all
into test1(id,col1,col2) values(id,col1,col2)
into test2(id,col3) values(id,col3)
select * from test;
commit;
SQL> select * from test;
ID COL1 COL2 COL3 COL4
