    A couple of things:

    1. What error does it come up with? Give us a fighting chance here.
    2. What happens if you run this query directly against your database?

    I was brought up to respect my elders. I don't respect many people nowadays.

      THE QUERY RUN SUCCESSFULLY AND IS IN THIS FORMAT:

      SELECT Robberies_Table.BankName, Robberies_Table.Region, Robberies_Table.BranchCode, Robberies_Table.[Date], Robberies_Table.Ammount,
      Robberies_Table.Description, Robberies_Table.Robbery_ID, Robberies_Table.[Year], Branches_Table.BranchName
      FROM (Robberies_Table INNER JOIN
      Branches_Table ON Robberies_Table.BranchCode = Branches_Table.BranchCode)

      IN C# THE QUERY I WRITE IS LIKE THIS : string Cmd = "SELECT * FROM (Robberies_Table INNER JOIN Branches_Table ON Robberies_Table.BranchCode = Branches_Table.BranchCode);"; AND WHEN I RUN THE PROGRAM NOW ONLY THE RECORD IS UNDER THE BRANCHNAME IT APPEAR IN SCREEN THE DATA OF ROBBERIES TABLE DON'T SHOW ME

        So use that query in your code.

            I don't know how many different ways I can put this, but try running the same query that you issue in your C# code in the SQL table. You can't run different queries and then expect them to be the same.

              MY DATABASE IS ACCESS NOT SQL AND I OBSERVE THAT HAS MANY DIFFERENCES IN THE WAY YOU WRITE THE QUERY. BUT ITS OK I WILL TRY MORE AND I WILL FIND THE SOLUTION ANYWAY... THANK YOU :)

                why is my query wrong at FROM ? i want to connect two tables so i can get some specific data but c# appear error. try { //Set the command string string Cmd = "SELECT * FROM Robberies_Table JOIN Branches_Table ON Robberies_Table.BranchCode =Branches_Table.BranchCode ;"; //create new new connection to the database OleDbConnection conn = new OleDbConnection(ConnectionString); //create new data adapter OleDbDataAdapter Adapter = new OleDbDataAdapter(Cmd, conn); //create new command builder OleDbCommandBuilder CmdBuilder = new OleDbCommandBuilder(Adapter); dTable = new DataTable(); Adapter.Fill(dTable); conn.Close(); } catch (Exception e) { MessageBox.Show(e.ToString()); } //return the search results on a datatable return dTable; }

                Would you plaese remove the * and write the columns that you want to access after joining both the table like-- select column1,column2 from (table1 JOIN table2 where.....)

                    I am so sorry if i make you to understand like this. I say this, because i felt that i had made you to feel tired about my problem with query in c# so i had preferred to release you from this, because maybe the problem didn't be the query but something that affect it. i am sorry again ..
