Would like to create a sample C# application with SQL Server 2008 connection.

I have a created a DatabaseTable in SQL 2008 - created and opened a connection using C# Code.

My task is to create a New Record and save it to the SQL 2008 (my DB).

What i would like to know is:

(i) How can i perform this only by using a Stored Procedure

(ii) How to call the Stored Procedure from my code.

Any help regarding this will be appreciated a lot!! Thanks in advance :)

In your code if you typed your connection string correct the following code should do it;

C#

using (var conn = new SqlConnection(connectionString))
using (var command = new SqlCommand("ProcedureName", conn) 
{
    CommandType = CommandType.StoredProcedure }) {
    conn.Open();
    command.ExecuteNonQuery();
    conn.Close();
}

If you need to use parameters in your StoredProcedure just add the parameters to the Parameters collection of the SqlCommand object.
Like:

C#

command.Parameters.AddWithValue("paramName", "paramValue");

Good luck,
OI

Hi,
Look at this links for creating procedures that are perform crud operations.
1-) http://www.novicksoftware.com/Articles/crud-operations-using-sql-server-stored-procedures-part-2.htm[^]

2-) http://www.pawlowski.cz/2011/01/automating-crud-procedures-generation-t-sql/[^]

And you may call your procedure like this;

C#

using (SqlConnection conn = new SqlConnection(getConnectionString()))
using (SqlCommand cmd = conn.CreateCommand())
{
    cmd.CommandText = parameterStatement.getQuery();
    cmd.CommandType = CommandType.StoredProcedure;
    cmd.Parameters.AddWithValue("SeqName", "SeqNameValue");

    var returnParameter = cmd.Parameters.Add("@ReturnVal", SqlDbType.Int);
    returnParameter.Direction = ParameterDirection.ReturnValue;

    conn.Open();
    cmd.ExecuteNonQuery();
    var result = returnParameter.Value;
}

This code is example for calling procedure. You may change paramters for your procedure.

Hope this will help you,
