Hi everyone,

I want to execute a sql stored procedure in C#. The procedure just inserts data into a table, therefore it has no parameters. I know how to do this,no sure what goes after the connection is open. :(

C#

string connectionString = "connect string...etc";

            
           string sqlstring = "execute myprocedure";

            OleDbConnection connection = new OleDbConnection(connectionString);

            OleDbCommand command = new OleDbCommand(sqlstring,connection);
          
     
            command.CommandType = CommandType.StoredProcedure;

            try 
              {
               connection.open();

                ??????????????????????

               connection.close();
                }

           catch (exception)

Please help.

Just execute the Command:

C#

command.ExecuteNonQuery();

It will Execute Procedure if your procedure does not require Parameters.

C#

Between Con.open() and con.close u try like this it will work
          try
          {
              connCmd = new OledbCommand(strSQL, dbConn);
              int i = connCmd.ExecuteNonQuery();
              if (i >= 1)
              {
                  //egreen
                  lblMessage.Text = "Suucess ";
              }
              else
              {
                  lblMessage.Text = "Fail ";
              }

          }
          finally
          {

1.
This is wrong!

sqlstring = "execute myprocedure";

If you plan to use CommandType.StoredProcedure it should be:

sqlstring = "myprocedure";

2.
Try this:

C#

using(OleDbConnection connection = new OleDbConnection(connectionString))
{
    OleDbCommand command = new OleDbCommand("myprocedure",connection);
    command.CommandType = CommandType.StoredProcedure;
 
    try 
    {
         connection.open();
         command.ExecuteNonQuery();           
    }
    catch (OledbExcpetion olex)
    {
         Debug.WriteLine(olex.ToString());
    }
    catch (Exception ex)
    {
        Debug.WriteLine(ex.ToString());        
    }
    finally
    {
        //if you are using try/catch block
        //this is better place for default connection closing
        connection.Close(); 
    }
}
