Oracle匿名块 loop循环插入一百万条数据

今天给大家带来一个小技巧：Oracle用匿名块 loop循环插入一百万条数据

declare
maxnumber constant number:=1000000;
i number :=1;
begin
for i in 1…maxnumber loop
insert into repayment2(a1,a2,a3,a4,a5,a6,a7,a8,a9,a10,a11,a12,a13,a14,a15,a16,a17,a18,a19,a20)
values(i,CONCAT(‘test’,i),CONCAT(‘test’,i),CONCAT(‘test’,i),CONCAT(‘test’,i),CONCAT(‘test’,i),CONCAT(‘test’,i),CONCAT(‘test’,i),
CONCAT(‘test’,i),CONCAT(‘test’,i),CONCAT(‘test’,i),CONCAT(‘test’,i),CONCAT(‘test’,i),CONCAT(‘test’,i),CONCAT(‘test’,i),CONCAT(‘test’,i),CONCAT(‘test’,i),
CONCAT(‘test’,i),CONCAT(‘test’,i),CONCAT(‘test’,i)); --CONCAT(‘test’,i)是将test与i进行拼接
end loop;
dbms_output.put_line(’ 成功录入数据！’);
commit;
end;
