ADOQuery Get Result (Delphi)

I Tried to get result from ADOQuery in Delphi. I wrote this function for Get a Name from table according custom ID.

function GetNameByID(Id : Integer) : string;
var query : string;
  Begin
  ShowMessage(GetDBGridViewIndex().ToString);
  query := 'SELECT Name FROM Table1 WHERE ID=' + IntToStr(Id);
  With ADOQuery do
    Begin
       try
          SQL.Clear;
          SQL.Add(query);
          Open;
          First;
          Result:= // Need Get Result;
       finally
          Close;
       end;
    End;
    
    ShowMessage(result);
End;

But I don't know how can return Result from ADOQuery.

TADOQuery is a descendant of TDataset. You can iterate through the result records with the First, Next, Prior, and Last methods and find out if you've reached the end with Eof.

Within each result record you can access the fields with:

Fields[Index].AsString
Fields[Index].AsInteger
...

or

FieldByName(FieldName).AsString
FieldByName(FieldName).AsInteger
...

In this case you can access to the result using:

Result := Fields[0].AsString;
Result := FieldByName('Name').AsString;

After you Open the query, the cursor is pointing the First record. You don't need to call the First method after Open.
