建立、改變和移除預存程序

在 SQL Server 管理物件 (SMO) 中，預存程序會由 StoredProcedure 物件表示。

若要在 SMO 中建立 StoredProcedure 物件，需要將 TextBody 屬性設定為定義預存程序的 Transact-SQL 指令碼。參數需要 @ 前置詞，且必須藉由使用 StoredProcedureParameter 物件以及加入至 StoredProcedure 物件的 StoredProcedureParameter 集合來個別地建立。

範例

如果要使用所提供的任何程式碼範例，您必須選擇建立應用程式用的程式設計環境、程式設計範本，及程式設計語言。如需詳細資訊，請參閱＜如何：在 Visual Studio .NET 中建立 Visual Basic SMO 專案＞或＜如何：在 Visual Studio .NET 中建立 Visual C# SMO 專案＞。

在 Visual Basic 中建立、改變和移除預存程序

此程式碼範例示範如何為 AdventureWorks2008R2 資料庫建立預存程序。以下範例在給定員工識別碼時會傳回員工的姓。預存程序需要一個輸入參數來指定員工識別碼，以及一個輸出參數來傳回員工的姓氏。

'Connect to the local, default instance of SQL Server.
Dim srv As Server
srv = New Server
'Reference the AdventureWorks2008R2 database.
Dim db As Database
db = srv.Databases("AdventureWorks2008R2")
'Define a StoredProcedure object variable by supplying the parent database and name arguments in the constructor.
Dim sp As StoredProcedure
sp = New StoredProcedure(db, "GetLastNameByEmployeeID")
'Set the TextMode property to false and then set the other object properties.
sp.TextMode = False
sp.AnsiNullsStatus = False
sp.QuotedIdentifierStatus = False
'Add two parameters.
Dim param As StoredProcedureParameter
param = New StoredProcedureParameter(sp, "@empval", DataType.Int)
sp.Parameters.Add(param)
Dim param2 As StoredProcedureParameter
param2 = New StoredProcedureParameter(sp, "@retval", DataType.NVarChar(50))
param2.IsOutputParameter = True
sp.Parameters.Add(param2)
'Set the TextBody property to define the stored procedure.
Dim stmt As String
stmt = " SELECT @retval = (SELECT LastName FROM Person.Person AS p JOIN HumanResources.Employee AS e ON p.BusinessEntityID = e.BusinessEntityID AND e.BusinessEntityID = @empval )"
sp.TextBody = stmt
'Create the stored procedure on the instance of SQL Server.
sp.Create()
'Modify a property and run the Alter method to make the change on the instance of SQL Server.   
sp.QuotedIdentifierStatus = True
sp.Alter()
'Remove the stored procedure.
sp.Drop()

在 Visual C# 中建立、改變和移除預存程序

此程式碼範例示範如何為 AdventureWorks2008R2 資料庫建立預存程序。以下範例在給定員工識別碼 (BusinessEntityID) 時會傳回員工的姓氏。預存程序需要一個輸入參數來指定員工識別碼，以及一個輸出參數來傳回員工的姓氏。

{
            //Connect to the local, default instance of SQL Server. 
            Server srv;
            srv = new Server();
            //Reference the AdventureWorks2008R2 database. 
            Database db;
            db = srv.Databases["AdventureWorks2008R2"];
            //Define a StoredProcedure object variable by supplying the parent database and name arguments in the constructor. 
            StoredProcedure sp;
            sp = new StoredProcedure(db, "GetLastNameByBusinessEntityID");
            //Set the TextMode property to false and then set the other object properties. 
            sp.TextMode = false;
            sp.AnsiNullsStatus = false;
            sp.QuotedIdentifierStatus = false;
            //Add two parameters. 
            StoredProcedureParameter param;
            param = new StoredProcedureParameter(sp, "@empval", DataType.Int);
            sp.Parameters.Add(param);
            StoredProcedureParameter param2;
            param2 = new StoredProcedureParameter(sp, "@retval", DataType.NVarChar(50));
            param2.IsOutputParameter = true;
            sp.Parameters.Add(param2);
            //Set the TextBody property to define the stored procedure. 
            string stmt;
            stmt = " SELECT @retval = (SELECT LastName FROM Person.Person,HumanResources.Employee WHERE Person.Person.BusinessEntityID = HumanResources.Employee.BusinessentityID AND HumanResources.Employee.BusinessEntityID = @empval )";
            sp.TextBody = stmt;
            //Create the stored procedure on the instance of SQL Server. 
            sp.Create();
            //Modify a property and run the Alter method to make the change on the instance of SQL Server. 
            sp.QuotedIdentifierStatus = true;
            sp.Alter();
            //Remove the stored procedure. 
            sp.Drop();
        }

在 PowerShell 中建立、改變和移除預存程序

此程式碼範例示範如何為 AdventureWorks2008R2 資料庫建立預存程序。以下範例在給定員工識別碼 (BusinessEntityID) 時會傳回員工的姓氏。預存程序需要一個輸入參數來指定員工識別碼，以及一個輸出參數來傳回員工的姓氏。

# Set the path context to the local, default instance of SQL Server and get a reference to AdventureWorks2008R2
CD \sql\localhost\default\databases
$db = get-item Adventureworks2008R2

# Define a StoredProcedure object variable by supplying the parent database and name arguments in the constructor. 
$sp  = New-Object -TypeName Microsoft.SqlServer.Management.SMO.StoredProcedure `
-argumentlist $db, "GetLastNameByBusinessEntityID"

#Set the TextMode property to false and then set the other object properties. 
$sp.TextMode = $false
$sp.AnsiNullsStatus = $false

$param2  = New-Object -TypeName Microsoft.SqlServer.Management.SMO.StoredProcedureParameter `
-argumentlist $sp,"@retval",$type
$param2.IsOutputParameter = $true
$sp.Parameters.Add($param2)

#Set the TextBody property to define the stored procedure. 
$sp.TextBody =  " SELECT @retval = (SELECT LastName FROM Person.Person,HumanResources.Employee WHERE Person.Person.BusinessEntityID = HumanResources.Employee.BusinessentityID AND HumanResources.Employee.BusinessEntityID = @empval )"
