Remarks

When you run sys.sp_rda_reauthorize_db (Transact-SQL) 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.

Examples

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.

DECLARE @credentialName NVARCHAR(128);

SET @credentialName = N'<existing_database_scoped_credential_name>';

EXEC sp_rda_reauthorize_db
    @credential = @credentialName,
    @with_copy = 1;
