Problem with database collation change (SQL Server 2008)

When I tried to change the collation of my existing database (including data) from ARABIC_CS_AS to PERSIAN_100_CS_AS the following error occurs:

Alter failed for Database 'XXXX'. (Microsoft.SqlServer.Smo)

An exception occurred while executing a Transact-SQL statement or batch. (Microsoft.SqlServer.ConnectionInfo)

The object 'ItemTables' is dependent on database collation. The database collation cannot be changed if a schema-bound object depends on it. Remove the dependencies on the database collation and then retry the operation.

The object 'CK_FilteredReportColumnFilters' is dependent on database collation. The database collation cannot be changed if a schema-bound object depends on it. Remove the dependencies on the database collation and then retry the operation.

The object 'CK_FilteredReportColumnFilters_1' is dependent on database collation. The database collation cannot be changed if a schema-bound object depends on it. Remove the dependencies on the database collation and then retry the operation.

The object 'CK_FilteredReportColumnFilters_2' is dependent on database collation. The database collation cannot be changed if a schema-bound object depends on it. Remove the dependencies on the database collation and then retry the operation.

The object 'CK_Reports' is dependent on database collation. The database collation cannot be changed if a schema-bound object depends on it. Remove the dependencies on the database collation and then retry the operation.

ALTER DATABASE failed. The default collation of database 'XXXX' cannot be set to Persian_100_CS_AS. (Microsoft SQL Server, Error: 5075)

Trying to correct the errors mentioned by removing those database objects causes another error with other titles in con开发者_运维百科version process.

Any idea ? Is there any well-defined solution to solve this problem?

Ahh, this is one of the worst problems in SQL Server: you cannot change the collation once an object is created (this is true both for tables and databases...).

You can only save your data (don't use bcp or backup utilities, you need to place them in a csv of similar file types...), drop the database, recreate with the right collation and re-import the data into the new database...

Hope this helps.

I have got the same issue and all objects were functions First takes full backup

script function as create. Delete these function then Run

use master
go
ALTER DATABASE xxx SET SINGLE_USER WITH ROLLBACK IMMEDIATE 
go
ALTER DATABASE xxx COLLATE yyyy
go
ALTER DATABASE xxx SET MULTI_USER
go

Recreate functions

I hope this helpful.

I have this problem because of my computed columns, so I just cancel computed columns and then change the collation and after that change the columns to computed columns. it works to me

I had the same problem. in my case altering the database with this query

use master
go
ALTER DATABASE xxx SET SINGLE_USER WITH ROLLBACK IMMEDIATE 
go
ALTER DATABASE xxx COLLATE yyyy
go
ALTER DATABASE xxx SET MULTI_USER
go

didn't give me any solution. and I ended up with errors!! So I created a new Database with the right collation, and I imported the table from one database to another.

Just create new database with ex database_b.change the collation according to your requirement and export from new source to target.

or

use alt collation tool which will override all the errors.

Just type N before writing your string.

for example:

insert into table values (N'yourstring')

N = unicode.
