retrieving rows by insertion order



Hello,

I vaguely remember reading in the manual that the order of the retrieved
rows in a response to a select statement is unpredictable (unless you
use an order by clause). this possibly depends on the indices set up for
the table and/or used in constructing the result etc. is this accurate?
if so is there any way to insure that rows retrieved are returning in
the order by were inserted in, say other than ordering by some
'insertion counter' (such a counter is of no use otherwise in my
application!).

thanks for the help.

Problem: I am fetching data from the database, storing it in a dataSet, and binding it with a Data Grid. The DataGrid controls allows sorting. The problem is that when the data is sorted on one of the columns in the Data Grid, and I then try to retrieve the selected row using the "SelectedRowIndex", I get the row as per the original order of data. Eg: If the order of rows is: C - A - B, which after sorting becomes A - B - C. Now, if I...

I am trying to write a conatiner which has std::map like methods but preserves the order of insertion. TO achieve this I thought of providing my own function for comparing the keys of the map.

Hi, I'm playing with dynamic script insertion to make a request to the server for a JavaScript file to be automatically run when it arrives in the browser. It works but... The page caching is too good. When I revisit the page or refresh the page, and then redo the script insertion, the browser doesn't even hit the server to check for a newer version of the JavaScript file. The same old script runs with each insertion.

Last Tip, we demonstrated the technique for retrieving data from a DAO Recordset, and placing it into a 2-dimensional Array using the GetRows() Method. This week, we will cover the same exact Method (GetRows()), but only as it applies to an ADO Recordset. Although there are similarities in the 2 methodologies, the ADO Method offers 2 more Optional Arguments, is a little more complex, and of course, the syntax is different in creating the...

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
