JDBC Internal Error

Question

Hello everyone.
I've reached the end of my abilities trying to see what I've done wrong here so I hope there is someone who knows how to fix this.
Environment:
Oracle client: 9.2.0.6
Oracle server: 9.2.0.5
JDBC: ojdbc14.jar OCI or THIN
Simplest case, an updatable ResultSet containing two columns, one VARCHAR2 and one TIMESTAMP(6).
Using updateString() to update the VARCHAR field works, using updateTimestamp() to update the TIMESTAMP field throws an SQLException with the text:
"Internal Error: unable to construct a Datum from the specified input"
and ErrorCode 17001.
The timestamp I use to update was retrieved using SQL "select CURRENT_TIMESTAMP from dual" and the getTimestamp(1) method inside the "ResultSet.next()" loop, just before calling the updateTimestamp() method.
I've seen an old thead with the same symptoms in this forum, unfortunately it was not resolved. Does anyone have any ideas? Please.
Regards,
Ed Lang

Answer 1

This error occured because of some changes in the nested table structure that we did. The fix for that was to drop all the fields that uses this nested table and reload it back with the changes to the structure. This fixed the problem. Earlier, we did not drop the field because we assumed that the new field added to the structure will be returned as null when the table is queried. Its wierd though because the sql worksheet client wasnt getting any errors, but the JDBC driver did.
It aint no easy workin with Oracle objects :(
thanks
