Database Insert and Delete with Stored Procedure

In my .aspx page, i have two textbox and one add button and one delete button.

I want simply, 开发者_如何学JAVAwhen entering data textboxes and click add button, adding to database with stored procedure.

When entering data textboxes and click delete button, delete from database with stored procedure.

How can I do that?

Simply I need 4 code part, add_click(), delete_click(), sp_add, sp_delete

How can I develop this 4 function?

Since you're giving us any hint what your table(s) look like and what your textboxes will be, this is just a "template" like approach.

BTW: you should not prefix your stored procedures with sp_ - that prefix is reserved for Microsoft.

proc_delete

Idea: you just pass in the primary key (usually an ID of some sort) to be deleted:

CREATE PROCEDURE dbo.proc_delete(@PrimaryKey INT)
AS
   DELETE FROM dbo.YourTable
   WHERE ID = @PrimaryKey

proc_add

You don't really tell us much about what you want to do ..... so here is one possibility

CREATE PROCEDURE dbo.proc_add(@value1 VARCHAR(50), @value2 VARCHAR(50))
AS 
    INSERT INTO dbo.YourTable(Value1, Value2)
    VALUES(@value1, @value2)

From your ASP.NET code, you would have to do the following:

• create a SqlConnection to the database
• create a suitable SqlCommand to execute the command you want
• set up the parameters and fill their values
• execute the proc

So in the case of the delete_click(), you'd have something like:

public void delete_click()
{
    using(SqlConnection _con = new SqlConnection(-your-connection-string-here-))
    using(SqlCommand _cmdDelete = new SqlCommand(_con, "dbo.proc_delete"))
    {
        _cmdDelete.CommandType = CommandType.StoredProcedure;

        // add parameter
        _cmdDelete.Parameters.Add("@PrimaryKey", SqlDbType.Int);
        _cmdDelete.Parameters["@PrimaryKey"].Value = (your key value here);

        // open connection, execute command, close connection
        _con.Open();
        _cmdDelete.ExecuteNonQuery();
        _con.Close();
    }
}

That would be the rough outline of how to do it - I'll leave the add_click() up to you!
