>>>>>>>Hi there,
>>>>>>>
>>>>>>>We are in the process of upgrading our databases from Sql Server 2005 to Sql Server 2012. All ports have been successful except one database that I designed 9 years ago.
>>>>>>>
>>>>>>>Every table has a primary index and most have foreign keys. Trying to update any record in any table with at least a foreign key generates an error "Syntaxe incorrecte vers '@error_number' " that translates into something like "'ncorrect syntax to '@errornumber' "
>>>>>>>
>>>>>>>There are no special user rights involved.
>>>>>>>
>>>>>>>The port has been done (1) with detach / attach and (2) from a backup and I observe the same behavior, which is somewhat reassunring :)
>>>>>>>
>>>>>>>The database is not set as readonly.
>>>>>>>
>>>>>>>I have compared the SQL 2005 and 2008 db instances and see no difference.
>>>>>>>
>>>>>>>So what?

>>>>>>>José
>>>>>>
>>>>>>Start SQL Profiler and see what is executed.
>>>>>Thanks Borislav,

>>>>>I show you the result in the attached picture (I am using Toad for SWL Server 6.0).

>>>>>Also I have to rephrase my last sentence: >I have compared the SQL 2005 and 2012 db instances and see no difference.

>>>>This is Execution plans, you need to run SQL Profiler (SSMS menu Tools->SQL Server Profiler)
>>>
>>>Hmm, sorry for using the wrong tool. The profiler has only two lines regarding this operation. Perhaps will you see something special.

>>>José

>>That is what you need.
>>Just copy and paste these line in New Query editor of SSMS and run it.
>>Then you will see where the error occurs.

>Ok, I hadn't notices the improvements in SSMS.
