Se não se importar de o ver como XML:

DECLARE @xmltmp xml = (SELECT * FROM table FOR XML AUTO)
PRINT CONVERT(NVARCHAR(MAX), @xmltmp)

Embora a pergunta do OP, tal como é feita, não necessáriamente exija isto, é útil que tenha vindo aqui procurar imprimir várias linhas/colunas (dentro da razão).

Se quiser imprimir várias linhas, poderá iterar através do resultado usando um cursor. por exemplo, imprimir todos os nomes de sys.bases de dados _cipais

DECLARE @name nvarchar(128)

DECLARE cur CURSOR FOR
SELECT name FROM sys.database_principals

OPEN cur

FETCH NEXT FROM cur INTO @name;
WHILE @@FETCH_STATUS = 0
BEGIN   
PRINT @name
FETCH NEXT FROM cur INTO @name;
END

CLOSE cur;
DEALLOCATE cur;

set @n = (select sum(Amount) from Expense)
print 'n=' + @n

Eu escrevi este SP para fazer o que você quer, no entanto, você precisa usar SQL dinâmico.

Isto funcionou comigo no servidor SQL 2008 R2

Tente esta consulta

DECLARE @PrintVarchar nvarchar(max) = (Select Sum(Amount) From Expense)
PRINT 'Varchar format =' + @PrintVarchar

DECLARE @PrintInt int = (Select Sum(Amount) From Expense)
PRINT @PrintInt

Adicionar

PRINT 'Hardcoded table name -' + CAST(@@RowCount as varchar(10))

Imediatamente após a consulta.

Também pode usar o procedimento não documentado sp_msforeachtable } armazenado como tal se quiser fazer isto para cada tabela:

sp_MSforeachtable @command1 ="PRINT 'TABLE NAME: ' + '?' DECLARE @RowCount INT SET @RowCount = (SELECT COUNT(*) FROM ?) PRINT @RowCount"

Pode haver uma maneira mais fácil,mas a primeira coisa que me vem à cabeça é:

Declare @SumVal int;
Select @SumVal=Sum(Amount) From Expense;
Print @SumVal;

Você pode, é claro, imprimir qualquer número de campos da tabela desta forma. Claro, se você quiser imprimir todos os resultados de uma consulta que retorna várias linhas, você apenas direcionaria sua saída apropriadamente (por exemplo, para texto).
