How do I move (INSERT+DELETE) the last n rows from a table in Jet SQL / Access 2003? -


I have a system that receives input from the public each day. When it starts every morning, I use a VB script Which will move every input into more than 500 backup tables. This system is a complete collection of activity.

I want to proceed from every line (from table 'active' to table 'active' in table 'collection' and then remove row from 'active') initial 500 rows (sorted by column Has been) from one table to another.

I was hoping to be able to do this as a single SQL statement, but I have not had much success. Is this a proper way to do a proper (nested) jet in the form of a SQL statement? Need to write some intermediate VB scripts to handle this action?

Thanks in advance,

It seems that I may have to do something like this . 

  Log in ChatArt (MsgId, MsgText, Filtered, LostFetched) SELECT MsgID, MsgText, Filtered, Last Feast with WHERE id & lt; = (Select from ChatCurrent MAX (id) - 500; Delete from ChatCurrent MsgId & lt; = (Select from ChatArchive MAX (MsgId); 500 Being the number of rows here I want to be in the system. Alternatively the MsgIds The list is to be stored anywhere (in VB) and to create another query from it.

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
