Oracle SQL Merge語句問題

Question

我有一個看起來或多或少像下面這樣的sql -

declare 
  some_Date date;
begin
select sysdate into some_Date from dual ; 
merge into 
  (SELECT cola, colb, colc FROM TableA  WHERE status='A'  AND some_id  = 101) P 
  USING ( select some_Date as cola from dual  ) S ON (P.cola=S.cola)
WHEN MATCHED THEN
  UPDATE SET P.status = 'D'
WHEN NOT MATCHED THEN
  INSERT
    (  cola, colb, colc    )
    VALUES
    ( xxx, xxx, xxx   );
end ;

當我通過直接用sysdate替換some_date來運行上述查詢時，它執行時沒有錯誤。 但我替換using子句中的sysdate並嘗試動態使用它我得到以下錯誤。 我得到一個例外如下 -

Error report:

ORA-00600: internal error code, arguments: [qcsfbdnp:1], [B1], [], [2], [], [], [], [], [], [], [], []
ORA-06512: at line 5
00600. 00000 -  "internal error code, arguments: [%s], [%s], [%s], [%s], [%s], [%s], [%s], [%s]"
*Cause:    This is the generic internal error number for Oracle program
           exceptions.  This indicates that a process has encountered an
           exceptional condition.
*Action:   Report as a bug - the first argument is the internal error number

這是oracle中的一個知道錯誤嗎？ 替補是什么？

更新：修正了錯字！

嘗試這個

merge into TableA  P 
USING ( select some_Date as cala from dual  ) S 
ON (P.cola=S.cola)
WHEN MATCHED THEN
  UPDATE SET P.status = 'D'
WHERE status='A'  AND some_id  = 101
WHEN NOT MATCHED THEN
  INSERT
    (  cola, colb, colc    )
    VALUES
    ( xxx, xxx, xxx   );
