Hello experts,

I'm facing the following  problem:
I have a website wich uses a SQL Server DB. I had it in a server with SQL_Latin1_General_CP1253_CI_AS collation. I recently transferred it in another server with SQL_Latin1_General_CP1_CI_AS collation. In first I had problems with Greek text, but with changing collations I managed to see right data in SQL Server environment. The problem is when I see in browser Greek text coming from temporary tables results.
What I mean is that when I browse the data of my SQL DB, all are right. When I browse data from tempdb I have ????? instead of Greek text.

Any ideas??

Thank Sotiris

Within SQL Server the collation are applicable in 2 place.

The database and the instance. The instance itself has a collation (Master,model,msdb) If you create a new database with a different collation then when you build temp tables they will always be in the instance collation.

One option to fix this would be to specify the collation with the create table statements so that it is created correctly. The other would be to reinstall the instance with the correct collation.

I' ve changed the collation within the table columns and the problem fixed when I see the results in the Management Studio environment.
The problem persists when I browse the data on IE or other browsers

are you using codepage=1253 in your page

and CHARSET
<META HTTP-EQUIV="Content-Type"
  CONTENT="text/html; CHARSET=windows-1253">

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Is the instance and the database the same collation now?

To AmmarR: I use windows-1253

To EvilPostIt: No, I just changed the collation on table columns. The instance collation is dificult to change because I host the site in a shared hosting

Ok so you have
your field in Nvarchar
your table collation 1253
Your Database Collation 1253
your Code page 1253
your CHARSET = windows-1253
.

and you still getting ????

i suggest try removing one record and after having all the above set correctly insert a single record in your table using the N
and test it in you browser

like example

Insert into Table (Greekfield) Values (N'Greekvalue')

and try view this record.
