Hi Appeon Support Team,

We recently migrated our PowerBuilder application to a new AWS server environment and are experiencing an issue that was not observed prior to the migration.

Error Details:

 

SQLSTATE = 23000

Microsoft OLE DB Driver 19 for SQL Server

Cannot insert duplicate key row in object 'ABC'

with unique index 'ABC_UI'.

The duplicate key value is (123455).

Issue Description: After the AWS server migration, users are intermittently encountering the above error while saving/inserting records into the ABC table. The same functionality was working as expected before the migration.

We would like to understand whether this issue could be related to:

PowerBuilder runtime behavior after migration

Microsoft OLE DB Driver 19 configuration

Transaction processing or commit behavior

Any PowerBuilder compatibility considerations in an AWS-hosted environment

Changes in how key values are generated or retrieved after the migration

Environment Details:

PowerBuilder Version: PB2022

Database: Microsoft SQL Server

Driver: Microsoft OLE DB Driver 19 for SQL Server

Current Environment: AWS Server

Operating System: Windows11

Observations:

The issue started only after the AWS migration.

The error indicates an attempt to insert a record with a key value that already exists in the table.

We are currently investigating whether the key value is generated by PowerBuilder, SQL Server Identity, Sequence, or custom application logic.

No application code changes were made as part of the migration.

Request for Assistance: Could you please advise if there are any known issues, configuration recommendations, or troubleshooting steps related to:

PowerBuilder applications running on AWS-hosted servers.

Microsoft OLE DB Driver 19 connectivity and transaction handling.

Identity/sequence value retrieval after migration.

Additional PowerBuilder tracing or logging that can help identify the source of the duplicate key value.
