If you open a table in an Access database, even if all you do is open it and never run a select query or anything, then Access modifies the mdb file, so the file timestamp will change. That is the way Access works, and there is nothing you can do about it.
As someone else has already pointed out, if you need to know when the data was last updated then you should build it in to your application in one way or another.

I'm not sure how you would get table modifications, however getting RECORD modifications is a VERY simple excercise, you do have a number of options. ALL of them require additional columns/fields to be added to the tables you want to monitor.
We monitor all tables so we have a Modified and ModifiedBy on all tables.
Add a timestamp field to the table and trigger it every time a record is saved, I think you can trigger this in access, not sure anymore.
From your UI pass in the userid and datetime whenever you write back to the database.
In your update/insert query automatically gather the current user and the datetime and add then to the update/save

Hi
I am comparing data between 2 tables looking for what exists in one so i can then enter whatis found into the second table as follows...
<pre>
mysql_select_db($database_Chartmenu, $Chartmenu);
$query_find_all = "SELECT hankypark.ID FROM hankypark LEFT JOIN tbl_ply_hankypark ON hankypark.ID = tbl_ply_hankypark.Song_ID WHERE (((tbl_ply_hankypark.Song_ID) Is Null))";
$find_all = mysql_query($query_find_all, $Chartmenu) or die(mysql_error());
$row_find_all = mysql_fetch_assoc($find_all);
$totalRows_find_all = mysql_num_rows($find_all);
</pre>
in the hankypark table i know will be entries that do not exist in the tbl_ply_hankypark table hense the Is Null query which gives me an array of the ID field, I now want to add those ID's to the tbl_ply_hankypark table. Question is what do I use to roll through all the ID's found ?
My INSERT query looks like this...as said what do use tat the begining is it a...
while or do or what?? and how should it be properly laid out please? not having played with arrays I have tried several things from suggestions on the net but none seem to work apart from one that only inserted the first ID and then stopped?
<code>
// Insert a row of information into the table "example"
mysql_query("INSERT INTO tbl_ply_hankypark (Song_ID) VALUES ('???')")or die(mysql_error());
</code>
Thought it best to just bite the bullet and come ask you guys cos your always right lol 
Cheers in advance of any help
Regards
Ray

Look into using an INSERT/SELECT statement.
|
|
|
|

One thing that you can do is combine an insert and a select command together, so you actually get the values inserted that you select from the select query. Your command becomes something like this:
INSERT INTO tbl_ply_hankypark(song_id)
SELECT hankypark.ID FROM hankypark
LEFT JOIN tbl_ply_hankypark ON
hankypark.ID = tbl_ply_hankypark.Song_ID
WHERE (((tbl_ply_hankypark.Song_ID) Is Null))

Oracle 11g is a massive beast. You need to clarify what you are looking for here - programming? DBA?

There's an ebook for this[^] one. The printed copy is excellent (I never buy ebooks, I prefer paper copy).
|
|
|
|

Isn't that fairly new, I be astonished if there were many books published yet.

Hi.
I have a problem with an xml.
I don't know how to read a piece o an xml.
This is the xml:
<root IDUtilizator="1" IDFormular="210">
<Forma R1="2" NumeCamp0="Numar" R2="20101006" NumeCamp1="Data" R3="2040" NumeCamp2="NrRegistratura" R4="20101006" NumeCamp3="DataRegistratura" R5="20100301" NumeCamp4="De la" R6="20101006" NumeCamp5="Pana la" R7="0" NumeCamp6="Data de referinta" R8="0" NumeCamp7="Tip persoana" R9="1000125" NumeCamp8="Tip taxa" R10="0" NumeCamp9="Utilizator" R11="0" NumeCamp10="Insolventi" R12="0" NumeCamp11="Sortare dupa" DataMod="20101006" />;
<Selectat Col1="PF-Da-Taxa apa apometru" />

Can you please advicing a very Good artical on Query optimization techniques SQL server database. currently my DB performance is very very slow. Pleaes advice.
Thanks in advance

you're welcome.

Here's what I'm trying to do, using C#:
1 - Connect to SQL Server
2 - Check if a database is present.
3 - Create the database if it isn't.
4 - Create a login/user pair for that database.
5 - Store the connection string for future use.
I have this done, confirmed by using SQL Server Management Studio Express.
The following method throws an SqlException:
private static SqlDataReader executeQuery(String query) {
SqlCommand command = new SqlCommand(query, Connection);
SqlDataReader reader;
try {
openConnection();
reader = command.ExecuteReader();
return reader;
} catch {
throw;
} finally {
}
}
The query: SELECT ReportGroupName FROM dbo.ReportGroups
The error message: Invalid object name 'dbo.ReportGroups'.
The offending line of code: reader = command.ExecuteReader();
Some lines from the script I used to create the database, tables and user:
CREATE LOGIN [bim] WITH PASSWORD=N'*******', DEFAULT_DATABASE=[master], DEFAULT_LANGUAGE=[us_english], CHECK_EXPIRATION=OFF, CHECK_POLICY=OFF
EXEC sys.sp_addsrvrolemember @loginame = N'bim', @rolename = N'dbcreator'
CREATE USER [bim] FOR LOGIN [bim] WITH DEFAULT_SCHEMA=[dbo]
CREATE TABLE [dbo].[ReportGroups]
I have a feeling that the problem lies with how I setup the default user, since I'm still learning databases, and it's been pretty hit or miss. However, the application worked previously using the above method with the same query string - the exception has only occurred recently, after creating the database from a script rather than in using the visual editors in SQL Server Management Studio. The script I used to create the database was derived from exports of the original database and tables, with only modifications made to create a login and a user.
Any assistance on tracking down how to fix this error would be greatly appreciated.

Hrm.
It appears that I wasn't setting InitialCatalog when building the connection string, at least not in the right place. You don't have to have an initial catalog when testing a connection to a database, which is code near what I'm doing, but you do have to have it to access database tables.
I was worried that it was something simple - turns out it was. Upon reflection, I'm kind of glad.

Hello everyone
I have a table named "volleyballpool8"
it has columns as ID, Pool, TeamNo, Team and Point
There are 11 rows in this table and there are 4 different "Pool"s, as A,B,C and D
Now
I need to make a SELECT statement to form a table, which:
1-Gets the ID, Team and Point of the row with the HIGHEST "Point" value of Pool='A's
2-adds the ID, Team and Point of the row with the SECOND HIGHEST "Point" value of Pool='B's
3-adds the ID, Team and Point of the row with the HIGHEST "Point" value of Pool='C's
4-adds the ID, Team and Point of the row with the SECOND HIGHEST "Point" value of Pool='D's
Therefore, in the end, I'll have a 4 rowed table
I'm somewhat new to SQL and I got confused...
Can anybody help?
btw: all of the fields are strings
|
|

|

I would appreciate any answer that makes the full query above but with some brute coding, I can handle myself in .cs part of the project if you only tell me how to get a "SECOND HIGHEST" from a table
for the highest of A's, I'm using
SELECT ID as row, Team, Point FROM cadet_games.volleyballpool8 WHERE Pool = 'A' and Point=(select max(point) from cadet_games.volleyballpool8)
If I don't get answer soon enough, I'll have to use multiple dataTables to concat later. But still I need some "second highest" query 
|
|
|
|

Hi,
question: what is the second highest in this collection: 4, 4, 2, 1? is it 4 or 2?
Anyway, you should look here[^].
