 ![Topic link icon](../../database-engine/configure-windows/media/topic-link.gif "Topic link icon") [Transact-SQL Syntax Conventions](../../t-sql/language-elements/transact-sql-syntax-conventions-transact-sql.md)  
  
## Syntax  
  
```  
  
sp_rda_reauthorize_db @credential = @credential, @with_copy = @with_copy [ , @azure_servername = @azure_servername, @azure_databasename = @azure_databasename ]  
```  
  
## Arguments  
 @credential = *\@credential*  
 Is the database scoped credential associated with the local Stretch-enabled database.  
  
 @with_copy = *\@with_copy*  
 Specifies whether to make a copy of the remote data and connect to the copy (recommended). *\@with_copy* is bit.  
  
 @azure_servername = *\@azure_servername*  
 Specifies the name of the Azure server that contains the remote data. *\@azure_servername* is sysname.  
  
 @azure_databasename = *\@azure_databasename*  
 Specifies the name of the Azure database that contains the remote data. *\@azure_databasename* is sysname.  
  
## Return Code Values  
 0 (success) or >0 (failure)  
  
## Permissions  
 Requires db_owner permissions.  
  
## Remarks  
 When you run [sys.sp_rda_reauthorize_db (Transact-SQL)](../../relational-databases/system-stored-procedures/sys-sp-rda-reauthorize-db-transact-sql.md) to reconnect to the remote Azure database, this operation automatically resets the query mode to LOCAL_AND_REMOTE, which is the default behavior for Stretch Database. That is, queries return results from both local and remote data.  
  
## Example  
 The following example restores the authenticated connection between a local database enabled for Stretch and the remote database. It makes a copy of the remote data (recommended) and connects to the new copy.  
  
```sql  
DECLARE @credentialName nvarchar(128);   
SET @credentialName = N'<existing_database_scoped_credential_name>';   
EXEC sp_rda_reauthorize_db @credential = @credentialName, @with_copy = 1;  
  
```
