SqlDataSource选择语句语法错误

Question

I'm working on an ASP page for a project, which should provide an interface for the user to maintain information on local little league baseball and softball. I keep getting an error:

Syntax error in FROM clause.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

when attempting to use a SqlDataSource with the following SelectCommand:

SELECT tblPlayers.PlayerCode, tblPlayers.First_Name,
                          tblPlayers.Last_Name, tblPlayers.Gender,
                          tblPlayers.Date_of_Birth, tblPlayers.League_age,
                          tblPlayers.InActiveStatus, 
                          tblParentMaster.ParentFirst+' '+tblParentMaster.Parentlast AS Parent_1,
                          tblParentMaster_2.ParentFirst+' '+tblParentMaster_2.ParentLast AS Parent_2,
                          tblPlayers.Birth_Certificate_on_file
                     FROM tblPlayers
                     JOIN tblParentMaster
                       ON tblPlayers.HOHCode = tblParentMaster.ParentCode
                     JOIN tblParentMaster AS tblParentMaster_2
                       ON tblPlayers.Parent2Code = tblParentmaster_2.ParentCode
                    WHERE (tblPlayers.PlayerCode = @PlayerCode)

In this code, @PlayerCode is the SelectedValue attribute of a GridView control on the page. I've already declared the ControlParameter for the SqlDataSource with the above SelectCommand:

<SelectParameters>
        <asp:ControlParameter ControlID="selectPlayerGridView" Name="PlayerCode"
            PropertyName="SelectedValue" Type="String" />
    </SelectParameters>

The SQL select statement is being used to populate data into a FormView. I'm not bothering to post the code for the FormView, sine it's a large chunk of code. I'm not brand new to SQL, but I don't have a lot of practical experience, either. Can someone please point out the syntax error? I appreciate any help, thanks.

AS you said in comment

If you are using .mdb file then it is an MS Access database then It should be connected using OleDb providers

and then your query should be like the following

SELECT tblPlayers.PlayerCode, tblPlayers.First_Name,
                          tblPlayers.Last_Name, tblPlayers.Gender,
                          tblPlayers.Date_of_Birth, tblPlayers.League_age,
                          tblPlayers.InActiveStatus, 
                          tblParentMaster.ParentFirst & ' ' & tblParentMaster.Parentlast AS Parent_1,
                          tblParentMaster_2.ParentFirst & ' ' & tblParentMaster_2.ParentLast AS Parent_2,
                          tblPlayers.Birth_Certificate_on_file
                     FROM tblPlayers
                     JOIN tblParentMaster
                       ON tblPlayers.HOHCode = tblParentMaster.ParentCode
                     JOIN tblParentMaster AS tblParentMaster_2
                       ON tblPlayers.Parent2Code = tblParentmaster_2.ParentCode
                    WHERE (tblPlayers.PlayerCode = @PlayerCode)

Replace + with &
