Guys,
I came across this error in ALRT log file.
ORA-00600 Internal error [12501]
It happened during this SELECT statement and it returned no rows,
after i dropped an index on FROMPROFNO column.
SELECT NAME,AGE,SEX FROM MSGHISTORY WHERE
( MEMNO = 123 AND PROFNO = 456 AND FROMMEMNO = 789 AND FROMPROFNO = 910 AND
SEX='MALE' AND POINT=1)
OR
( MEMNO = 124 AND PROFNO = 457 AND FROMMEMNO = 789 AND FROMPROFNO = 910 AND
SEX='MALE' AND POINT=1)
this statement was working fine and was returning rows b4 i dropped the index.
as soon as i created an index on FROMPROFNO , it returned rows.
why is it behaving so ?
whether is there or not , i should be getting the rows.
but it is not so ?
if there is index , i get the data and if it is not there i dont get data.
and what may be reason of ORA 600 [12501] error ?
when is this error expected ?
help me guys ?
TIA.
Jp.
