请问如何在Oracle中将值转换成存文本的值？

如题，我是将读取到的值保存在long型的数据中，这段数据里面有类似于

insert into QX_NEWS
  (v_xwid,
   V_FLID,
   v_ztid,
   v_xwlb,
   v_top,
   v_dwid,
   v_bt,
   d_fbdate,
   v_sh,
   v_nr,
   v_manid,
   v_lmmanid,
   d_lmdt,
   N_READCNT)
values

其中红色标记的部分总是出错，将我数据中的标点符号也做为ora的符号读取了，我就想把红色部分的值改成纯文本或者字符串内的值，可以实现么？
