Existe um análogo de GETDATE() que retorna DATETIME2

  • 772

De acordo com o MSDN, Getdate(), GetUtcDate() e CURRENT_TIMESTAMP todos retornam DATETIME. Fiz um pequeno teste, que confirma que:

CREATE TABLE #t(T DATETIME2(7));
GO

DECLARE @i INT ;
SET @i=1;

WHILE @i<10000 BEGIN ;
INSERT #t VALUES(CURRENT_TIMESTAMP) ;
SET @i=@i+1;
END ;

SELECT DISTINCT t 
FROM #t 
ORDER BY t ;

Existe uma função semelhante que retorna DATETIME2(7)?
