oracle中去除空格一般用rtim、ltrim，但是不能用这两个去除tab，这时可以

update BAS_Forwarding set SOURCEONCE=replace(SOURCEONCE,chr(09),'') where warehouseid like '111%';

chr(09)是tab的ascii码

csv文件导入oracle后，存在大量的tab，这时可以用游标批量去除tab：

declare
v_colunm_name varchar2(30);
cursor c1 is SELECT column_name FROM user_tab_columns where table_name = upper('BAS_Forwarding');
begin
open c1;
  loop --提取一行数据到c1
    fetch c1 into v_colunm_name;
    --判读是否提取到值，没取到值就退出
    --取到值c_job%notfound 是false
    --取不到值c_job%notfound 是true
    exit when c1%notfound;
    update BAS_Forwarding set SOURCEONCE=replace(SOURCEONCE,chr(09),'') where warehouseid like '111%';
  end loop;--关闭游标
  commit;
exception 
  when others then
    dbms_output.put_line('出错'||sqlerrm);
    rollback;
close c1;
end;
