Hello,I have a C++ / MFC app which uses CDatabase and CRecordset to connect to aODBC data source for a SQL Server 7 database. The application workedproperly with a MySQL database, but after swapping it for SQL Serverproblems emerged. In particular, any calls to CRecordset::AddNew() andCRecordset::Edit() cause an exception to be thrown with the error message"Recordset is read-only". Stepping through the code for CRecordset::Open(),I can see that it indeeds fail to open the recordset with SQL_CONCUR_ROWVERand SQL_CONCUR_LOCK, finally succeeding with SQL_CONCUR_READ_ONLY. I need tobe able to write to the db!! What is going on here??I call CRecordset::Open() with no SQL string and no options (which defaultsto full access and not read-only).I am not a SQL Server expert, but I tried playing with the config a littlebit:- The database is NOT set for read-only.- The database option "Restrict Access" is NOT selected.- I checkmarked all permissions (SELECT, INSERT, UPDATE, DELETE, DRI)for my app's user on all tables in the db.- My connection string uses the user 'sa', which is the login name forthe user 'dbo'.In the ODBC data source config, I set authentication to SQL Serverauthentication, and accepted the default for all the other options.I haven't tried using a different class (say, CDaoRecordset) nor do I planon doing that. I really need to get this to work with CRecordset. Any helpis appreciated.Thanks,SL
I'm trying to do Sharepoint DR with Log Shipping and every thing configured except one thing which is switch the WSS_Content (Standby /Read-Only) DB to be ready and Write.
I tried from
GUI or ALTER DATABASE [WSS_Content] SET READ_WRITE WITH NO_WAIT
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?

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?
Is it possible to set READ UNCOMMITTED to a user connecting to an SQL2000 server instance? I understand this can be done via a front endapplication. But what I am looking to do is to assign this to aspecific user when they login to the server via any entry application.Can this be set with a trigger?
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 am trying to cycle through a table and trigger an event based on some critera. I am not sure how to do it. I am a classic VBA guy, so I might be way off: Dim myConnection As SqlConnection Dim myCommand As SqlCommand myConnection = New SqlConnection("MY SQL DATA SOURCE") myConnection.Open()
myCommand = New SqlCommand("SELECT * FROM history", myConnection) Dim dr = myCommand.ExecuteReader() Dim i As Integer = 1
While dr.read() i = i + 1 ' HOW DO I CYCLE THROUGH THE ROWS AND ASK IF A FIELD EQUALS A VALUE ' field name = "Tail"
hi I have 3 tables:Article,Source and File. Each article can have multiple filenames. The fields of table Article are:ArticleID,SourceID,ArticleDate,ArticleCategory The fields of table Source are:SourceID,SourceName the fields of Table File:ID,ArticleID,Filename Select*from Article inner join Source on Article.SourceID=source.SourceID order by ArticleDate I obtain a number of recordsets from the above query. Then for each recordset(Rs1),Let's say for the first recordset Rs1.MoveFirst I want to apply this query: Rs2.Open"Select SourceName,ArticleDate,File.Filename from [RS1] inner Join File on Article.ArticleID=File.ArticleID I want from the above query to have the Filenames corresponding to each Article because in my VB form I have 2 command buttons:one gives me the article's definition(Date,Source) and the other gives me the Filename of the current recordset(Article) The above SQL syntax is it correct?
SELECT TOP 2 MenuComments, MenuDate, MenuID, MenuIsActive, MenuName FROM Menu ORDER BY MenuDate DESC
This orders the data correctly, but the problem is, I need ONLY the SECOND row, not the top row. Also, because I am sorting for menus entered into the system, I cannot use a variable based on real dates (in other words, I can't use the server clock to help filter the results).
Any and all help would be GREATLY appreciated -- I've been banging my head against this one all day!
I am using classic ASP. Records are grouped together by a GroupUnique number. Some groups are small with about 10 records, othere are larger at about 160.
For each record, I have about 50 columns of data that I need to display on a webpage. Because the 50 columns don't easily fit on the one page, I create two tables, each displaying 26 columns, the first columnn being an ID column. Due to the size of groups, sometimes the tables are very large - and when they get too big it overloads the server.
I think the main problem is the two tables. I use two recordsets (one of them is shown below - although instead of a SELECT * I do in fact name the columns needed for each table). I have to use two because the Recordsets don't like me using the ID column again - once it is used it is gone.
Is there a better way to store all of this information so that I can just use the one recordset? Possibly in an array? Is there a more efficient way of getting the data?
<% Dim Recordset4__MMColParam1 Recordset4__MMColParam1 = "1" If (Scramble.Fields.Item("GU").Value <> "") Then Recordset4__MMColParam1 = Scramble.Fields.Item("GU").Value End If %>
I am having some problems. I'm pretty new to sql and really dont know how to achieve more than the basic selects etc.,
My problem is that I have a recordset on one page http://www.photoghetto.com/photo-images/animals.asp that returns the results of all the images in one category. In this case it's animals and wildlife.
The user can click on any image and go to a page that shows a larger detail version of the image. http://www.photoghetto.com/photo-images/animals-photo-detail.asp
What I do is post the ProductID number to this page so that the selected thumb is shown. So for exmaple for the image of the wild cat it is http://www.photoghetto.com/photo-images/animals-photo-detail.asp?ProductID=6
My problem is that on the animals-photo-detail.asp the user has to be able to "scroll" through all the images from the category.
I.e should be able to hit the previous image button and see the stallion image, or the next button to see the butterfly etc., and thus scroll through all the images on this age if he/ she wishes to.
I understand the principles of having a results page and then being able to click on one of the results and getting a detail page. Such as I have it here. With the http://www.photoghetto.com/photo-images/animals.asp as a results page listing all the results of the category, and then when the user clicks on one of the results, goes to a detail page, for example, http://www.photoghetto.com/photo-images/animals-photo-detail.asp?ProductID=6.
My problem is that what I need is the recordset from the listing page to function on the detail page so that the user can scroll through the results in the same order that they were on the results page.
I have searched now for a couple of days online and every tutorial I find shows the same structure. Results Page > Detail Page.
The sql i am using on the detail page is simply,
<% Dim photos_rs__MMColParam photos_rs__MMColParam = "1" If (Request.QueryString("ProductID") <> "") Then photos_rs__MMColParam = Request.QueryString("ProductID") End If %>
So I understand why it will only display the one result since thats the detail page.
Is it possible to be able to scroll through the results using the previous and next buttons as I have setup in the display on the http://www.photoghetto.com/photo-images/animals-photo-detail.asp page. For example, http://www.photoghetto.com/photo-images/animals-photo-detail.asp=ProductID=6.
Since the resutls are gathered from across the database its not possible to have a href tage that does a <<< http://www.photoghetto.com/photo-images/animals-photo-detail.asp=ProductID=(6 -1) or a >>> http://www.photoghetto.com/photo-images/animals-photo-detail.asp=ProductID=(6+1).
I guess it has to be something with a recordset index but does anyone know how to do it? And does anyone have the ability to help me do it?
My boss is kicking my butt now to get this thing online at some point today, and I'm turning to you guys for help if possible.
I'm sorry if this is a stupid question. I've really ran out of ideas.

Im doing a select that should retrieve a name from one table and display thenumber of correct bets done in the betDB (using the gameDB that has info onhow a game ended)I want the "MyVAR" value to be used in the inner select statement withouttoo much hassle. As you can see im trying to get the "MyVAR" to insert inthe bottom line of the code.Whats the quick fix to this one..?Thanks in advance :-)---------- code begin ----------select memberDB.memberID as MyVAR, (select count(GamesDB.GameID)from GamesDBinner join GameBetDBon GameBetDB.betHome = GamesDB.homeGoal and GameBetDB.betAway =GamesDB.awaygoalinner join memberDBon memberDB.memberID = GameBetDB.memberIDwhere GamesDB.gameID=GameBetDB.gameIDand GameBetDB.memberID= MyVAR ) as wins from memberDB---------- code end ----------
I am connecting to the database as following: set con = server.createobject("adodb.connection") con.open "connectionstring" set rs = con.execute("select * from tablename")
I am able to display the records but if I want to give adopenstatic to the above connection, how can I do so?
I have some problems to edit a recordset in an ActiveX DTS using Vbscript. Here is an example of the script :
dim varsql, varset, varconn set varconn = CreateObject("ADODB.Connection") set varset = CreateObject("ADODB.Recordset") varconn.Open = "Provider=SQLOLEDB.1;Data Source=(local);Initial Catalog=Enregistrement3;user id = 'sa';password=''"
if varset.recordcount >0 then do while varset.eof varset.edit ......................... varset.update varset.movenext loop end if varset.close varconn.close
Does someone see what is wrong ? I allways get -1 for the varset.recordcount ! (I checked there are some records into the table). I don't think it is a problem of user's right as it works with the same user configuration using a SQL action requery. If I modify the open statement like this : varset.Open varsql, varconn, 1 varset.recordcount contains the good number of records but the recordset is read noly and can't be modified...
<!--- Update the DISTANCE field on STORE table ---> <cfquery name="UpdateZips" datasource="#application.data#" username="#application.username#" password="#application.password#"> exec Stores_UpdateZipSeachInfo '#Dist#', '#zip2.zipcode#' </cfquery> </cfloop>
I'm an SQL novice, but I know this must be a common problem.
I'm trying to select a recordset (using ASP), but I know I only want part of the recordset, and am not sure how to limit it ahead of time.
For example, the query will return about 500 rows, but I know I only want to use a small section of these records. I want to give the user the ability to navigate through small sections of these 500 rows without having to get all rows all the time. I know ahead of time which rows to get, but have no idea how to limit the recordset before I get it (there is no fields in the database to help).
This is what I'm doing now. "select * from xyz where id=xxx order by date desc;" I know I only want the first 10, or 10-20, or 400-410. The way I'm doing it now, I'm getting the whole recordset each time, doing a "rs.move x" where x is where I want to start. This is really a waste of network traffic and memory since my SQL server is on a different machine as the web server running ASP.
How do I do this?
Please email me if you could at pmt@vantagenet.com
i have a select query that returns multiple rows (within a cursor). How do i loop through the rows to process it (in a stored proc)? I donot want to use nested cursors. a code sample is requested.
id | value ========== 1,abc 1,def 1,ghi 2,def 2,jkl
I want these values to go horizontally into another table matched on id, to look like this:
id | value ======== 1,abc def ghi 2, def jkl
I built a cursor to parse through it but was taking forever (there's 185,000 records in the reference table). Any idea's on the fastest way to perform this function?
I was wondering if there is a way to randomise a recordset once you have performed a query. eg I want my query return a set of records based upon criteria supplied and then either randomise the order of the recordset or only return 3 random records - which every is simplest to do.
Can this be done in SQL or do I need to handle it outside of my SQL query in my business logic?
'Use the ADO connection that Access uses Set cn = CurrentProject.AccessConnection
'Create an instance of the ADO Recordset class, and 'set its properties Set rs = New ADODB.Recordset With rs Set .ActiveConnection = cn .Source = RecSourceFloater .LockType = adLockOptimistic .CursorType = adOpenKeyset .CursorLocation = adUseServer .Open End With
'Set the form's Recordset property to the ADO recordset Set WeekDay.Form.Recordset = rs

When I edit the form I noticed that I could not go back to a recently added record because it was not available, so I concluded that I had to force an update, which I do in the before update event of my form, as follows;
'Update the underlying recordset Me.Recordset.Update
It works great on my test server here, but when I instal it on the SQL Server 2000 - I get an error 'EOF' or 'BOF' is true......... so it fails
This is a C++ / ADO / SQL question. Maybe not the right forum but I am guessing there are some programmers out there ...
