    (@SupplierID     bigint,
     @ReferenceNo     NVARCHAR(20),
     @PurchaseDate     DATETIME,
     @CurrentPurchaseID bigint output)

AS

INSERT INTO [tblPurchases]
     ([SupplierID],
      [PurchaseNo],
      [ReferenceNo],
      [PurchaseDate])
 
VALUES
    (@SupplierID,
     @PurchaseNo,
     @ReferenceNo,
     @PurchaseDate)

SET @CurrentPurchaseID=SCOPE_IDENTITY()



Data Access Layer should look like this.

 Public Sub InsertPurchase()

        Try
           Dim DB As Database = DatabaseFactory.CreateDatabase(CWB_DBCONNECTION_STRING)
            Dim DBC As DbCommand = db.GetStoredProcCommand(PURCHASES_INSERT)
            db.AddInParameter(DBC, "@SupplierID", DbType.Int64, Me.SupplierID)
            db.AddInParameter(DBC, "@ReferenceNo", DbType.String, Me.RefBillNo)
            db.AddInParameter(DBC, "@PurchaseDate", DbType.DateTime, Me.PurchaseDate)
            db.AddOutParameter(DBC,"@CurrentPurchaseID", DbType.Int64, 0)       

            db.ExecuteNonQuery(DBC)

            Me.CurrentPurchaseID = Convert.ToInt64(db.GetParameterValue(DBC, "@CurrentPurchaseID").ToString())
        Catch ex As Exception

            Throw
        End Try

    End Sub

 

CurrentPurchaseID  has new value of identity column.

About the Author

ASP.NET Community
United States United States
The ASP.NET Wiki was started by Scott Hanselman in February of 2008. The idea is that folks spend a lot of time trolling the blogs, googlinglive-searching for answers to common "How To" questions. There's piles of fantastic community-created and MSFT-created content out there, but if it's not found by a search engine and the right combination of keywords, it's often lost.

The ASP.NET Wiki articles moved to CodeProject in October 2013 and will live on, loved, protected and updated by the community.
