Hello developer Team,

I have an issue with a simple core query on the primary key:

ora-00600: internal error code, arguments: [qkeexhs], [121], [] ...

I tried two differents methods to achieve this goal with same error:

Method 1:

return await context.Set<TEntity>().FindAsync(id);

Method 2:

return await context.Set<Application>()
.Include(...)
.ThenInclude(...)
.SingleOrDefaultAsync(app=>app.id = id)

It's a code first application, the migration/seed data and other operations like (ToListAsync, AddSync ...) have been executed correctly. The issue seem to be only on FindAsync and SingleOrDefaultAsync operations.

The environment is:

Visual studio 2017, EntityframeworkCore.tools (2.1.1), devart.data.oracle.efcore (9.6.646) with direct connection.

Thank you, for your help.

The error is caused by Oracle Server itself. Refer to http://www.dba-oracle.com/t_ora_00600_i ... string.htm. We recommend you to contact the Oracle Support Team.

You can deploy your application to another Oracle Server instance with a new database to make sure that the application works.

Hi,

if someone has the same problem:

The issue was solved without any intervention from the oracle side.
Only an update to net core 2.2 instead of 2.1 and devart version 9.7.734 instead of 9.6.634.

Ty,

Thank you for your feedback.
