insert into ch_flat (colunm1,column2) select column1,column2 from ch_flat@test
这条语句如何在存储过程中加入循环,插入1W条数据commit
------解决方案--------------------
- SQL code
declare -- Local variables here begin -- Test statements here for i in 1..10000 loop insert into ch_flat (colunm1,column2) select column1,column2 from ch_flat@test; end loop; commit;end;
------解决方案--------------------
declare
-- Local variables here
begin
-- Test statements here
for i in 1..10000
loop
insert into ch_flat (colunm1,column2) select column1,column2 from ch_flat@test;
end loop;
if i= 100000
then
commit;
else null;
end;
------解决方案--------------------
你可以定个变量 查出一万提交一次 170万就是 170次 当变量等于 170的时候 就跳出循环
------解决方案--------------------
bulk collect加limit,再用forall

8楼可以不过就是代码多慢。
declare
v_cmt_cnt number:=0;
begin
for c in(select rowid rid,rownum r from ch_flat@test)
loop
insert into ch_flat (colunm1,column2) select column1,column2 from ch_flat@test where rowid=c.rid;
if(mod(c.r,10000)=0)then
commit;
v_cmt_cnt:=v_cmt_cnt+1;
end if;
end loop;
commit;
dbms_output.put_line('commited times:'||v_cmt_cnt);
end;
------解决方案--------------------
- SQL code
declare n_count number:=0;CURSOR c IS SELECT colunm1,column2 FROM ch_flat; begin for my_c in c loop insert into ch_flat (colunm1,column2) select my_c.column1,my_c.column2; n_count:=n_count+1; if mod(n.count,10000)=0 then commit; end if; end loop; commit; end;
