Counting Records in an  SQL Table by G.F. Weis Gfw


--------------------------------------------------------------------------------

I was working on a project using my C# Class Generator  and realized that I had no way to get a count of the number of records in the table. In the past I have used the DataAdapter class - easy, but not very efficient.

I ran accross a post on one of the discussion forums and decided to build a new function in my class generator appropriately named RecordCount. The function returns an 'int' with the number of records in the table.

m_dbConnection is the Connection string to your database
aRepresentative is the name of our table
Id is unique column used in our table
Using the C# Class Generator, the generated code is as follows:


public int RecordCount() // Get Count of Records
{
    int recCount=0;
    string countCmd = "SELECT Count(Id) AS Total FROM aRepresentative ";
    SqlConnection m_SqlConnection = new SqlConnection(m_dbConnection);
    SqlCommand    m_SqlCommand    = new SqlCommand(countCmd, m_SqlConnection);
    try
    {
        // Open the Connection ----------------------------
        m_SqlCommand.Connection.Open();
        recCount = (int)m_SqlCommand.ExecuteScalar();
    } // end try
    catch (Exception e)
    {
        throw new Exception("Error in RecordCount() -> " + e.ToString());
    }
    finally
    {
        m_SqlConnection.Close();
        m_SqlCommand.Dispose();
    }
    return recCount;
} // end Select
