How To Remember Last Record Read
Jul 23, 2005
Hi,
Can you guys see if there's a solution to this problem?
I have a database from which I have to read each record and process
that record. New records are being added all the time, so I need to go
back and check for new records and process them.
However:
-- there is no 'identity' column in the database design (so I cannot
keep track of the last record read by use of a numeric variable)
-- I am not allowed to update the database (so I cannot flag the
records I have read).
My problem is: how can I know which records I have already read and
which ones I haven't read yet? I don't want to process records twice
and don't want to miss any records.
Is there a known solution to this problem? Any ideas?
Thanks.

Ok,
I have a table with the following fields:
ID, Type, Name, Date, Description
ID is the PK. Names all have different values, but are predefined... a visual:
ID, Type, Name, Date, Description
1, monday, mon1234,3-3-08, some text
2, monday, mon1234,3-4-08, some text
3, monday, mon2345, 3-5-08, some text
4, monday, mon2345, 3-6-08, some text
Now What i need to do is get the last report for each unique "Name". How would I do that?
When I try to do a Select Distinct, of course, it only gives me those names that only appear once.

Hi.
I have a table where I need to set some rows to Read only (to protect the rows from being edited). Can I do this with a trigger checking against a column (where dataReadOnly = 1)?
Or is there a better way?

Using this system function (::fn_dblog(null,null)) you find out how many transactions are been confirmed in your .LDF. Although by means of another system function you can see further information, i mean statistical ones.
Any help would be very appreciated.

Hello,
A while ago I installed SQL CE on my decive. Unfortunately, it crapped out at one point so I'm reinstalling what needs to be put back on. I'm pretty sure I just used the CAB files to do this (but I might be mistaken). In any case, I remember there being an application that allowed me to do queries, browse data, etc. on my device's databases... I'm pretty sure it was just something included with SQL CE.
I already have the CF installed. I have all of the SQL CE CABs installed as well (I think)... but for some reason I simply cannot remember what CAB or other installation that would contain the browser, query creation thing, and so on...
Anyone have any idea what I'm rambling on about? Thanks!

my script:-
declare @db_pswd nvarchar(4000);
declare @len1 int = 16,
@min tinyint = 40,
@range tinyint = 74,
@exclude varchar(50) = '11cdtyuXR#0:;<=>?@O[]`^/abfty#$%^&1234567890*',

Hi all,
I have a report in which the user can drill down on data. However when the user changes a parameter and reruns the report, all nodes are collapsed again. Is it possible to let the report keep the expansion state of nodes after pressing the 'view report' button again?

Both the OLE DB Connection and ADO.Net Connection in SSIS Package does not remember password.
Im connecting to a SQL Server 2000 box using its sa password as test.
The SSIS package runs fine when you first set up the connection in bids
The bottom line is that SSIS keeps forgetting the password I feed into
the two Connections that I'm using. I double-click a connection,
type the password in, check "Save my password" and hit "OK" but the
password disappears from there whenever I run the package or
double-click the connection again.
is there any known workaround for this issue as I would like to schedule my SSIS package using a SSIS Step in a SQL Server 2005 Agent job.
the only thing I found when googling this error was link below but the workaround described here is a little harsh

thanks in advance
Dave
the box SSIS is running on is Windows 2003 Server Standard Edition latest service pack
SQL Server 2005 (no service packs )

I have two database files, one .mdf and one .ndf. The creator of these files has marked them readonly. I want to "attach" these files to a new database, but cannot do so because they are read-only. I get this message:
Server: Msg 3415, Level 16, State 2, Line 1
Database 'TestSprintLD2' is read-only or has read-only files and must be made writable before it can be upgraded.
What command(s) are needed to make these files read_write?
thanks

i have a database which get refreshed every day from client's data . and we need to pull heavy data from them every day as reports . so only selects happens on that database.
we do daily population of some table in some other databases from this daily refreshed DB.
will read uncommitted or NOLOCK with select queries to retrieve data faster.
there will be no dirty read as there are NO DML operation in that database so for SELECT which happens concurrently on these tables , will NOLOCK work?

On the login prompt for Report Server, there is a checkbox option to "Remember my Password." I check this, login successfully... but when returning to the Report Server, I am again prompted for the password, although the user name is saved. No matter how many times I do this, the password will not save in IE7. I have tried this on 3 different computers with IE7. In IE 6, I do not even get the checkbox as an option, just the user name/password prompt. In Firefox, the password saves fine. Any ideas what would be causing this?
Thanks,
Brian

OK, I'm using VS2003 and I'm having trouble. The page works perfectly when I created it with WebMatrix but I want to learn more about creating code behind pages and this page doesn't work. I think it has some things to do with Query builder but I can't seem to get change outside "please register". I have the table populated and it is not coming back with "login successful" or "password wrong" when I've entered correct information. Enclosed is what I've done in VS2003. Can you see where my error is? Any help would be greatly appreciated.
Thanks again.

Hi
I have a table with a user column and other columns. User column id the primary key.
I want to create a copy of the record where the user="user1" and insert that copy in the same table in a new created record. But I want the new record to have a value of "user2" in the user column instead of "user1" since it's a primary key
Thanks.

Hey all!
Sorry for the less then descriptive post title but I didn't find a better way to describe it. I'm developing an app in the express editions of VB and SQLserver. The application is a task/resource scheduler. The main form will have a datepicker or weekly overview and show all tasks scheduled per day. The problem is, I've got one or more people assigned to tasks and I wonder what's the best way to design this. Personally, I'd go for one Task table, a People table and a table that provides a link between them (several record per task, one for each person assigned linking TaskID and PplID). However, I don't see a nice way of showing this data to the end user, allowing him to edit/add etc on ONE screen.
To fix that the only way I see is just add columns to the Task table for every person with select boxes. This way everything can be done on one simple screen. This obviously does present some future issues.
On top of this, which people are available on a day varies and there should be an option to allow a user to set who is available on a specific day. Which would lead me to my first idea and add another table that would provide this. but then I'm having design issues again for the form.
I'm kinda stuck atm, can anyone shed some light on this. I'm sure there is an elegant way of doing this but I'm failing at finding it.
Thanks in advance,
Johan

Hi,
We're running a Sage CRM install with a SQL Server 2000 database at the back end. We're using the Sage web services API for updating data and a JDBC connection to retrieve data as it's so much quicker.
If I retrieve a record using the JDBC connection and then try and update the same record through the web services, the query times out as if the record is locked for updates. Has anyone experienced anything similar or know what I'm doing wrong? If I just use DriverManager.getConnection() to establish the connection instead of the datasource, and then continue with the same code I don't get these record locking problems. Please find more details below.
Thanks,
Sarah
The JDBC provider for the datasource is a WebSphere embedded ConnectJDBC for SQL Server DataSource, using an implementation type of 'connection pool datasource'. We are using a container managed J2C authentication alias for logging on.
This is running on a Websphere Application Server v6.1.
Code snippet - getting the record thru JDBC:
DataSource wsDataSource = serviceLocator.getDataSource("jdbc/dsSQLServer");
Connection wsCon = wsDataSource.getConnection();
// wsCon.setAutoCommit(false); //have tried with and without this flag - same results
Statements stmt = wsCon.createStatement();
String sql = "SELECT * FROM Person where personID = 12345";
ResultSet rs = stmt.executeQuery(sql);
if(rs.next()){
System.out.println(rs.getString("lastName"));
}
if (rs != null){
rs.close();
}
if (stmt != null) {
stmt.close();
}
if (wsCon != null) {
wsCon.close();
}

I am attempting to create a multi-record file (as described in my last thread) and have found the following set of instructions very helpful:

I have been able to create a sample file with two of my record types.
I now need to build on this further, because I have 9 record types in total that need to be extracted to a single flat file.
does anyone have any ideas how I might extend the example above to include more record types or know of another means of achieving this?
Thanks in advance for any help you might be able to provide.
