ExecuteSQLTask.SqlStatementSource Proprietà

public:
 property System::String ^ SqlStatementSource { System::String ^ get(); void set(System::String ^ value); };

public string SqlStatementSource { get; set; }

member this.SqlStatementSource : string with get, set

Public Property SqlStatementSource As String

Valore della proprietà

Una stringa che indica il nome della sorgente che contiene l'istruzione SQL che il task Execute SQL esegui.

Implementazioni

Esempio

Il seguente esempio crea un ExecuteSQLTask, poi mostra le impostazioni predefinite delle proprietà, inclusi i SqlStatementSource, usando il TaskHost. Poi imposta il valore oltre SqlStatementSource ad alcune proprietà per mostrare come impostare i valori delle proprietà.

Commenti

La stringa sorgente può essere l'istruzione SQL stessa, un gestore di connessione a un file che contiene l'istruzione SQL, o il nome di una variabile che contiene l'istruzione SQL, a seconda dell'impostazione dell'enumerazione SqlStatementSourceType .
