Precompilers, OCI & OCCI :: How To Detect Offending Record For Update Statement

way to run an update statement through OCI and make it stop on the first offending record and then identify that record? Here is an example of what I need to do: I run an update with 5 records in the input buffer like this:

- the 1st record exists in the table
- the 2st record exists in the table
- the 3rd record does not exist in the table
- the 4rd records exists in the table but is violating some unique constraint
- the 5nd record exists in the table

I need to report that the 4th record from the input buffer has a problem, and then commit records 1, 2 and 3. Do not commit record 5. So far I have tried the following:

- OCIStmtExecute with OCI_DEFAULT. It stops on the first error, but I don't know how to identify the bad record. OCI_ATTR_ROW_COUNT returns the number of affected records in the target table. I didn't find any other attributes that would return 4, for the 4th bad record in the input buffer.

- OCIStmtExecute with OCI_BATCH_ERROR. I can identify the bad records in the input buffer by using OCI_ATTR_DML_ROW_OFFSET. However, OCIStmt Execute does NOT stop on the first violating record. It loads the whole input buffer and then reports which records were in error. I don't know how to commit only up to the first bad record -- the 4th in the example.
