How do I change db schema to dbo

Question

I imported a bunch of tables from an old sql server (2000) to my 2008 database. All the imported tables are prefixed with my username, for example: jonathan.MovieData

Answer 1

USE MyDB;
GO
ALTER SCHEMA dbo TRANSFER jonathan.MovieData;
GO

Ref: ALTER SCHEMA

Answer 2

Way to do it for an individual thing:

alter schema dbo transfer jonathan.MovieData

Answer 3

Use this code if you want to change all tables, views, and procedures at once.

BEGIN
DECLARE @name NVARCHAR(MAX)
        , @sql NVARCHAR(MAX)
        , @oldSchema NVARCHAR(MAX) = 'MyOldSchema'
        , @newSchema NVARCHAR(MAX) = 'dbo'
        
DECLARE objCursor CURSOR FOR
        SELECT  o.name
        FROM    sys.objects o
        WHERE   type IN ('P', 'U', 'V')

OPEN    objCursor
        FETCH NEXT FROM objCursor INTO @name
        WHILE   @@FETCH_STATUS = 0
        BEGIN
            SET @sql = 'ALTER SCHEMA '+ @newSchema +' TRANSFER '+ @oldSchema + '.' +  @name         
            BEGIN TRY
                exec(@sql)
                PRINT 'Success: ' + @sql
            END TRY
            BEGIN CATCH
                PRINT 'Error executing: ' + @sql
            END CATCH
            FETCH NEXT FROM objCursor INTO @name
        END
CLOSE   objCursor
DEALLOCATE  objCursor

END

It will execute a code like this

ALTER SCHEMA dbo TRANSFER MyOldSchema.xx_GetUserInformation

I just posted this to a similar question: In sql server 2005, how do I change the "schema" of a table without losing any data?

---

A slight improvement to sAeid's excellent answer...

I added an exec to have this code self-execute, and I added a union at the top so that I could change the schema of both tables AND stored procedures:

DECLARE cursore CURSOR FOR 


select specific_schema as 'schema', specific_name AS 'name'
FROM INFORMATION_SCHEMA.routines
WHERE specific_schema <> 'dbo' 

UNION ALL

SELECT TABLE_SCHEMA AS 'schema', TABLE_NAME AS 'name'
FROM INFORMATION_SCHEMA.TABLES 
WHERE TABLE_SCHEMA <> 'dbo' 



DECLARE @schema sysname, 
 @tab sysname, 
 @sql varchar(500) 


OPEN cursore     
FETCH NEXT FROM cursore INTO @schema, @tab 

WHILE @@FETCH_STATUS = 0     
BEGIN 
 SET @sql = 'ALTER SCHEMA dbo TRANSFER [' + @schema + '].[' + @tab +']'    
 PRINT @sql   
 exec (@sql)  
 FETCH NEXT FROM cursore INTO @schema, @tab     
END 

CLOSE cursore     
DEALLOCATE cursore

I too had to restore a dbdump, and found that the schema wasn't dbo - I spent hours trying to get Sql Server management studio or visual studio data transfers to alter the destination schema... I ended up just running this against the restored dump on the new server to get things the way I wanted.

Answer 5

ALTER SCHEMA dbo TRANSFER jonathan.MovieData;

See ALTER SCHEMA.

Generalized Syntax:

ALTER SCHEMA TargetSchema TRANSFER SourceSchema.TableName; 

Answer 6

I had a similar issue but my schema had a backslash in it. In this case, include the brackets around the schema.

ALTER SCHEMA dbo TRANSFER [DOMAIN\jonathan].MovieData;
