Dynamisches SQL wird abgeschnitten, obwohl es nvarchar (max) ist

Question

declare @sql6 nvarchar(max) = '' 

set @sql6 = @sql6 + ' CODE' 

EXEC sp_executesql @SQL6 

Gibt es einen Fall, in dem das Deklarieren eines dynamischen SQL auf diese Weise abgeschnitten werden könnte?

Es ist eine Reihe von Code, nicht eine Wand aus Text einfügen möchten, aber die print-Anweisung endet mit:

GROUP BY 
    T1.TreatmentID, T1.SamplingRandomNumber, 
    T1.ProductID, T1.OptimizationGroupID, 
    T1.CurrencyCode, C.CalculatedFromText, 
    T1.TreatmentOrdinal, T1.SourceCode, 
    T1.[IsPriorBoo 

, wo es ein paar mehr sein sollte.

Der Fehler ist

falsche Syntax nahe ''.

Answer 1

Sie haben wahrscheinlich zwei Probleme hier. Sie beziehen sich auf die PRINT-Anweisung - dies wird bei 8000 Bytes (4000 Zeichen, seit Sie nvarchar verwenden) stoppen. Wenn Sie die gesamte Abfrage in SSMS anzeigen möchten, können Sie sie am besten für die Ausgabe in XML umwandeln, wodurch Sie ein Feld erhalten, auf das Sie in SSMS klicken und das gesamte Objekt anzeigen können.

In der kurzen Bit der Abfrage sichtbar, Sie haben tatsächlich ein zusätzliches Angebot hier im ersten Teil Ihres DANN, die zumindest bricht, dass ein Teil der Anfrage:

CASE WHEN T.CalculatedFromText = 2 THEN PS.CalculatedFromText + ' + CAST(T.TreatmentOrdinal AS char)
