J'essaie d'imprimer une valeur sélectionnée, est-ce possible?
Exemple:
PRINT
SELECT SUM(Amount) FROM Expense
Vous savez, il existe peut-être un moyen plus simple mais la première chose qui me vient à l’esprit est:
Declare @SumVal int;
Select @SumVal=Sum(Amount) From Expense;
Print @SumVal;
Vous pouvez, bien sûr, imprimer autant de champs de la table de cette manière. Bien entendu, si vous souhaitez imprimer tous les résultats d'une requête renvoyant plusieurs lignes, vous devez simplement diriger votre sortie de manière appropriée (par exemple, vers le texte).
Si vous êtes d'accord pour le visualiser en XML:
DECLARE @xmltmp xml = (SELECT * FROM table FOR XML AUTO)
PRINT CONVERT(NVARCHAR(MAX), @xmltmp)
Bien que la question du PO telle qu'elle est posée ne l'exige pas nécessairement, il est utile si vous cherchez à imprimer plusieurs lignes/colonnes (dans des limites raisonnables).
Si vous souhaitez imprimer plusieurs lignes, vous pouvez parcourir le résultat en utilisant un curseur . affiche tous les noms de 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;
set @n = (select sum(Amount) from Expense)
print 'n=' + @n
J'ai écrit ceci SP pour faire exactement ce que vous voulez, mais vous devez utiliser SQL dynamique.

Essayez cette requête
DECLARE @PrintVarchar nvarchar(max) = (Select Sum(Amount) From Expense)
PRINT 'Varchar format =' + @PrintVarchar
DECLARE @PrintInt int = (Select Sum(Amount) From Expense)
PRINT @PrintInt
Vous pouvez également utiliser la procédure stockée sp_MSforeachtable undocumented telle quelle si vous souhaitez le faire pour chaque table:
sp_MSforeachtable @command1 ="PRINT 'TABLE NAME: ' + '?' DECLARE @RowCount INT SET @RowCount = (SELECT COUNT(*) FROM ?) PRINT @RowCount"
Ajouter
PRINT 'Hardcoded table name -' + CAST(@@RowCount as varchar(10))
immédiatement après la requête.
Si vous souhaitez (comme moi) avoir des résultats contenant plusieurs rangées de diverses requêtes SELECT "étiquetées" et que vous ne puissiez pas gérer cela avec les contraintes de l'instruction PRINT et de l'onglet Messages, vous pouvez le modifier et simplement ajouter des messages Onglet Résultats ci-dessous:
SELECT 'Results from scenario 1'
SELECT
*
FROM tblSample
