SQL Server PRINT SELECT (Drucken eines ausgewählten Abfrageergebnisses)?

Question

Ich versuche einen ausgewählten Wert zu drucken, ist das möglich?

Beispiel:

PRINT 
    SELECT SUM(Amount) FROM Expense 

Answer 1

Wissen Sie, es könnte ein einfacher Weg, aber das erste, was in den Sinn erscheint ist:

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

Sie können, natürlich, drucken Sie es Anzahl der Felder aus der Tabelle auf diese Weise. Wenn Sie natürlich alle Ergebnisse einer Abfrage drucken möchten, die mehrere Zeilen zurückgibt, würden Sie Ihre Ausgabe einfach entsprechend ausrichten (z. B. an Text).

Answer 2

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

Answer 3

Wenn Sie mehrere Zeilen drucken möchten, können Sie das Ergebnis mit einem Cursor durchlaufen. z.B. drucken alle Namen von sys.database_principals

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; 

Answer 4

ich das SP schrieb genau das zu tun, was Sie wollen, aber Sie müssen dynamische SQL verwenden.

Answer 5

Wenn Sie mit der Anzeige als XML OK sind:

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

Während die Frage des OP, da dies nicht unbedingt erforderlich gefragt ist, ist es nützlich, wenn Sie hier bekam suchen mehrere Zeilen/Spalten drucken (innerhalb Grund).

Diese Abfrage

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

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