Creating, Altering, and Removing a Stored Procedure in Visual Basic

This code example shows how to create a stored procedure for the AdventureWorks2008R2 database. The example returns the last name of an employee when it is given the employee ID number. The stored procedure requires one input parameter to specify the employee ID number and one output parameter to return the last name of the employee.

'Connect to the local, default instance of SQL Server.
Dim srv As Server
srv = New Server
'Reference the AdventureWorks database.
Dim db As Database
db = srv.Databases("AdventureWorks")
'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.Contact,HumanResources.Employee WHERE Person.Contact.ContactID = HumanResources.Employee.ContactID AND  HumanResources.Employee.EmployeeID = @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()

Creating, Altering, and Removing a Stored Procedure in Visual C#

This code example shows how to create a stored procedure for the AdventureWorks2008R2 database. The example returns the last name of an employee when it is given the employee ID number (BusinessEntityID). The stored procedure requires one input parameter to specify the employee ID number and one output parameter to return the last name of the employee.

            //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");
