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?
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"
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?

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

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;

Hi,I have table where i have the following fields in datasheetview:id | date | image | question1 | question2 | question..NI would like to have it in this way:id | date | image | questionnr | answer1 01-01-2004 test.tif 1 1000 (this is the value offield question1)As you can see the first 3 fields remains the same, but the records of those3 fields should be inserted for each record of the question fields. I can dothis with a union query for each questionfield, but.....How can i do this automatically, because there are more than 500 columns.
pCadors->Open (_T"select foo from bar", pCadoCon->m_lpDispatch, eCursor); //SQL: a select statement here
The CADOConnection and CADORs are ADO connection, RecordSet wrapper classes created with ClassWizard.
I successfully open an ADO connection using the OEM driver by this DSN less way, and then passed it to ADO Recordset. From ODBC trace, I found that under the cover of the ADO, this connection is used to execute the select statement, but after that it automatically opens an other connection. I do not know why and is it possible to disable this?
Hi, Can anyone tell me how can i remove records from a recordset through an IS script? Also how can i write some records to an excel file from a script as well?
I have a stored proc which returns a very large recordset (150,000 rows +). Each row has upto 65 - 95 fields. I need to do row transformations on each row.
I am using an Execute SQL Task to execute the stored procedure to return the results into a Object variable which I then shred inside a Source Script Component (by casting it into a recordset datatable and looping it and assinging into an Output columns).
Obviously the recordset variable is enormous - stuffed with 150K large rows. But what choices do I have in this scenario? Can I persist the recordset variable to disk? I cannot stream the result of a stored proc execution. So what I do about the sluggish performance of this enormous variable?
I'm updating an ADO recordset inside VB6... We just moved the database from SQL Server 2000 to SS2205....

i am using .NET front end and back end SQL Server 2k. for insert, update, delete and select queries what should i use stored procedure or direct sql through front end.
