ORA-00600: [qerrmObnd1], [932], [ORA-00932: inconsistent datatypes

     今天幫客戶巡檢資料庫,資料庫報以下錯誤:

ORA-00600: internal error code, arguments: [qerrmObnd1], [932], [ORA-00932: inconsistent datatypes: expected  got
根據trace查出來的sql如下:

    select to_char(bq.rk_rq,:"SYS_B_00") ZS_XM,:"SYS_B_01" ZS_PM,bq.bqrk_je BQRK_JE,to_char(bq.rk_rq,:"SYS_B_02") RK_RQ--,sq.bqrk_je SNTQ_JE,case when sq.bqrk_je>0 then (bq.bqrk_je-sq.bqrk_je)/sq.bqrk_je when sq.bqrk_je =0 then 1 end ZJL,bq.bqrk_je-nvl(sq.bqrk_je,0) ZJ_JE
,decode((select nsrnbm from  t_dcfx_dcfxbg where nsrnbm = :"SYS_B_03" and bgssq_z = to_char(bq.rk_rq,:"SYS_B_04") ),:"SYS_B_05",:"SYS_B_06",:"SYS_B_07") fxbg
   from
(select :"SYS_B_08" ZS_XM,:"SYS_B_09" ZS_PM,(sum(nvl(a.bqrkse,:"SYS_B_10")) -sum(nvl(a.bqtkse,:"SYS_B_11"))) BQRK_JE,trunc(a.sj,:"SYS_B_12") RK_RQ
  from a
  where
     trunc(a.sj,:"SYS_B_13") = trunc(to_date(:"SYS_B_14",:"SYS_B_15"), :"SYS_B_16")
    and a.nsrnbm =:"SYS_B_17"  group by trunc(a.sj,:"SYS_B_18"))bq,
(select :"SYS_B_19" ZS_XM,:"SYS_B_20" ZS_PM,(sum(nvl(a.bqrkse,:"SYS_B_21")) -sum(nvl(a.bqtkse,:"SYS_B_22"))) BQRK_JE,trunc(a.sj,:"SYS_B_23") RK_RQ
  from a
  where
     trunc(a.sj,:"SYS_B_24") = trunc(add_months(to_date(:"SYS_B_25",:"SYS_B_26"),-:"SYS_B_27"), :"SYS_B_28")
    and a.nsrnbm =:"SYS_B_29"  group by trunc(a.sj,:"SYS_B_30"))sq
    where
      bq.RK_RQ = add_months(SQ.RK_RQ,:"SYS_B_31")

根據查metalink,有可能是bug

檢查下資料庫引數為 cursor_sharing=SIMILAR  觸發這個bug

以下是metalink解釋

Description

This problem appears to have been introduced in 9.2.0.6 .

When CURSOR_SHARING = FORCE or SIMILAR then SQL over database
links which involves replaced date format mask information 
can result in ORA-600 [qerrmObnd1] and a dump in qerrmOdcl.

Workaround:
  A workaround in 9.2.0.6 is to set the hidden parameter
  "_adjust_literal_replacement" = TRUE
  This enables the fix for .
