Ok i have switched from Access to SQL and i have a quick question.
I'm creating a stored procedure to handle the the IDENTITY
OK i'm just wondering since the UniquieID will be carried over to multiple tables i only need the 1 stored procedure from the main primary key table? And in that procedure i only need to reference @ID and not (@firstname etc...)
Also in the vb.net code the parameters are of the whole table, in this instance can i just simply have the parameter of the identity?
Thanks for your help
I'm creating a stored procedure to handle the the IDENTITY
Code:
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE PROCEDURE [dbo].[RETURNID]
@FirstName varchar(50),
@LastName varchar(50),
@BirthDate datetime,
@City varchar(50),
@Country varchar(50),
@id int output
AS
BEGIN
SET NOCOUNT ON;
INSERT INTO Employees (FirstName, LastName, BirthDate, City, Country)
VALUES (@FirstName, @LastName, @BirthDate, @City, @Country)
SET @id=SCOPE_IDENTITY()
RETURN @id
ENDCode:
'Without Output parameter
Dim strConnString As String = ConfigurationManager.ConnectionStrings("conString").ConnectionString
Dim con As New SqlConnection(strConnString)
Dim cmd As New SqlCommand()
cmd.CommandType = CommandType.StoredProcedure
cmd.CommandText = "RETURNID"
cmd.Parameters.Add("@FirstName", SqlDbType.VarChar).Value = txtFirstName.Text.Trim()
cmd.Parameters.Add("@LastName", SqlDbType.VarChar).Value = txtLastName.Text.Trim()
cmd.Parameters.Add("@BirthDate", SqlDbType.DateTime).Value = txtBirthDate.Text.Trim()
cmd.Parameters.Add("@City", SqlDbType.VarChar).Value = txtCity.Text.Trim()
cmd.Parameters.Add("@Country", SqlDbType.VarChar).Value = txtCountry.Text.Trim()
cmd.Connection = con
Try
con.Open()
Dim obj As Object = cmd.ExecuteScalar()
lblMessage.Text = "Record inserted successfully. ID = " & obj.ToString()
Catch ex As Exception
Throw ex
Finally
con.Close()
con.Dispose()
End TryAlso in the vb.net code the parameters are of the whole table, in this instance can i just simply have the parameter of the identity?
