ADO.NET :: Ado And Access - Sum Query SELECT SUM() As Total
Dec 31, 2010
Need to do a summary report of two items, sales and commissions by sales person, by date range. There are only a handful of salespeople. I messed around with SELECT SUM() for a few hours last night. It works easily, up until you need to do a few table joins, to say join on employee id to pull in names. Then it starts getting pretty convoluted, fairly quickly. Question is, is there maybe an easier way of doing this in asp.net than through the sql? It is Access, so I don't think LINQ will work, right? Just wondering if there isn't a quick, easy way of doing this that I don't know about.
Currently I run 2 separate queries to update + retrieve a tickent number. What happens if there're 2 users clicking on the same button at the same time? Could somehow two updates being run first and then both users get back the same ticket number?
string mySql = "UPDATE TicketCounter SET TicketNumber = (TicketNumber + 1)"; OleDbConnection myConnection = new OleDbConnection(accessConnStr); OleDbCommand myCmd = new OleDbCommand(mySql, myConnection); myCmd.Connection.Open(); myCmd.ExecuteNonQuery(); mySql = "SELECT TicketNumber FROM TicketCounter" myCmd.CommandText = mySql; OleDbDataReader myReader = myCmd.ExecuteReader();

How to display the total number of records returned in a GridView in asp.net? I want to display it in a label or if possible next to the page index in GridView... And how to provide a select option in a GridView to select all records (It should select not only the record shown in one page in GridView but all records that were returned to the GridView) or one by one record that was returned? These things (for e.g., Number of selected rows) should also be displayed in the label which I mentioned before.

However, I get the error "System.Data.SqlClient.SqlException: The multi-part identifier "lblUn.Text" could not be bound." when I attempt to load the page after logging in. How can I fix this?
