Upon re-reading your original post, I see that you didn't mention the Partition Key datatype, I just assumed it was Date - almost all of ours are. My suggestion to look at your range definitions for each partition still hold, whether Date, Number, or whatever. The other possibility that occurred to me is how you're, perhaps, translating the raw data via the SQL*Loader control file. If the Partition Key data is Date, do you have a SQL function that converts a string value to Date? Perhaps that's not working correctly. If the loaded values aren't Date, might the SQL function be converting a string to Number? Yet another thought. Jack C.

Just a thought. Jack C. Applewhite Austin I.S.D. "Brady, Mark" <Mark.Brady@xxxxxxxxxxxxxxxxx> Sent by: oracle-l-bounce@xxxxxxxxxxxxx 08/30/2007 04:17 PM Please respond to Mark.Brady@xxxxxxxxxxxxxxxxx To <oracle-l@xxxxxxxxxxxxx> cc Subject Inserts into Partitioned Table fail with Ora-14400 We’re inserting records via SQL*Loader into a 9.2.0.6. The table is Range Partitioned. The last partition is defined as Maxvalue. If you have a maxvalue partition it should not be possible to see Record 8: Rejected - Error on table LEAVES. ORA-14400: inserted partition key does not map to any partition But every record fails. MaxValue should be just like an “else”, right? And the docs say that Nulls go to maxvalue partitions. Either the value is less than some partition we defined or less than maxvalue but it’s not unmappable. What am I missing? Thanks, Mark Brady
