oracle中基于分隔符的字符串拆分[重复]

Question

我在 oracle 表中有这样的字符串

VM4 SPLA - WI NS V R STD #P59- 9 9 99 QTY 2 : S P LA - W IN SV RENT #P39-9999 QTY 3 : SPL A - WIN S VR SMB # P 3 9- 999 99 QTY 5    1

我需要拆分这个字符串并使用循环插入到表中

name description           partnumber   Qty  objectstate
-------------------------------------------------------
VM4  SPLA - WI NS V R STD  P59- 9 9 99   2    1
VM4  S P LA - W IN SV RENT P39-9999      3    1
VM4  SPL A - WIN S VR SMB  P 3 9- 999 99 5    1

帮助我如何使用循环来做到这一点。

  v_objstate := to_number(regexp_substr(string, '\d+$'));

  end loop;
