Here I will explain how to insert registered user details in database and how to get output parameters returned by SQL Query in asp.net.
Description
I have one registration form that give a chance to register new user .In registration form user needs to enter fields UserName, Password, Confirm Password like this I have nearly ten fields are there now I need to check whether this username already exists or not if username not exists I need to register user otherwise I need to display message like username already exists I am doing this thing using query. Here is the link it will explain how to write sql query to return output parameters
Now I need to display that output parameter message during user registration in asp.net. How to get that output parameter returned by SQL query.
To get output parameters in asp.net we need to write statements like this in codebehind
Here @ERROR is output parameter name returned from query
For sample design your aspx page like this
spx page
Here sp_userinformation is name of stored procedure created in database and@ERROR is
output parameter name returned by query if you want to write query to

Stored procedure with output parameter in sql server
Now I need to display that output parameter message during user registration in asp.net. How to get that output parameter returned by SQL query.
To get output parameters in asp.net we need to write statements like this in codebehind
| cmd.Parameters.Add("@ERROR", SqlDbType.Char, 500); cmd.Parameters["@ERROR"].Direction = ParameterDirection.Output; string message = (string) cmd.Parameters["@ERROR"].Value; |
For sample design your aspx page like this
spx page
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>OutPut Pasrameters Sample</title>
</head>
<body>
<form id="form1" runat="server">
<table align="center">

<tr>

<td align="right" >
<asp:Label ID="lbluser" runat="server" Text="Username"></asp:Label>

<asp:TextBox ID="txtuser" runat="server"></asp:TextBox>
</td>
</tr>
<tr>

<td align="right" >
<asp:Label ID="lblpwd" runat="server" Text="Password"></asp:Label>

<span style= "color:Red; font-weight :bold"> <asp:Label ID="lblErrorMsg" runat="server"></asp:Label></span>
</td>

</table>
</form>
</body>
</html>

In Codebehind write following code in btnsubmit_Click like this
Codebehind
protected void btnsubmit_Click(object sender, EventArgs e)
{
if (txtpwd.Text == txtcnmpwd.Text)
{
string UserName = txtuser.Text;
string Password = txtpwd.Text;
string ConfirmPassword = txtcnmpwd.Text;
string FirstName = txtfname.Text;
string LastName = txtlname.Text;
string Email = txtEmail.Text;
string Phoneno = txtphone.Text;
string Location = txtlocation.Text;
string Created_By = txtuser.Text;
SqlConnection con = new SqlConnection("Data Source=MYCBJ017550027;Initial Catalog=MySamplesDB;Integrated Security=True");
con.Open();
SqlCommand cmd = new SqlCommand("sp_userinformation", con);
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.AddWithValue("@UserName", UserName);
cmd.Parameters.AddWithValue("@Password", Password);
cmd.Parameters.AddWithValue("@FirstName", FirstName);
cmd.Parameters.AddWithValue("@LastName", LastName);
cmd.Parameters.AddWithValue("@Email", Email);
cmd.Parameters.AddWithValue("@PhoneNo", Phoneno);
cmd.Parameters.AddWithValue("@Location", Location);
cmd.Parameters.AddWithValue("@Created_By", Created_By);
cmd.Parameters.Add("@ERROR", SqlDbType.Char, 500);
cmd.Parameters["@ERROR"].Direction = ParameterDirection.Output;
cmd.ExecuteNonQuery();
message = (string) cmd.Parameters["@ERROR"].Value;
con.Close();
}
else
{
Page.RegisterStartupScript("UserMsg", "");
}
lblErrorMsg.Text = message;
}
