Question

我有一个看起来或多或少类似下面的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 ;

当我通过直接用sysdate替换some_date来运行上述查询时，它执行时没有错误。但我替换using子句中的sysdate并尝试动态使用它我得到以下错误。我得到一个例外如下 -

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

这是oracle中的一个知道错误吗？什么是候补？

更新：修正了错字！

试试这个

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   );
