Simple General SQL Question...any Help Would Be Appreciated
Sep 25, 2007
Hi, sorry if this is not the right place to post, any help or direction would be appreciated. I'm using SQLServer2005.
I'm having trouble writing a query and could do with some help. I'll illustrate the problem with an example.
Say I have 2 tables.
Table 1 - tbl_news:
ID
NewsTitle
linkedDoc1
linkedDoc2
1
my news title
5
3
Table 2 - tbl_docs:
ID
docTitle
1
doc1
2
doc2
3
doc3
4
doc4
5
doc5
Now, I'd like to write a query which returns bascially the first table, but which gets the doc title from table 2 using the IDs....how would I write this?
I have a table that we use for audit trail purposes and I need toevaluate the last row that was enetered for a particular case to seeif it meets certain criteria and if it does I need to return all therows that pertain to that case. Thanks in advance for the help.
CREATE TRIGGER [tr_update_doc_count] ON [Documents] FOR INSERT AS [Declared variables]
[I want to get the tablereference from the inserted information] SELECT @tableref = Table_id, @Account_id = Account_id from inserted
[Then I get the Actual Table Name from the UsercreatedTables Table where it is stored] SELECT @tablename = TableName from UsercreatedTables WHERE Table_id = @tableref
[Now I want to use the @tablename I got from UsercreatedTables in the query] SELECT @Current_Doc_Count = Account_Docs from @tablename WHERE Account_id = @Account_id
I am not sure how to get it to use the variable @tablename for the table name in the last query. It gives me an error stating that @tablename is invalid syntax.
g'day gents, I run a select query against my mysql database using asp.net. The query looks like this: SELECT distinct(rubbet.ortnamn) as Bebyggelsenamn, count(rubbet.ortnamn) as 'Antal',min(rubbet.artal) as Beläggsår, rubbet.belaggsform as Beläggsform, rubbet.harad as Härad, rubbet.socken as Socken, rubbet.ovrigt as Övrigt, rubbet.filnamn as Filnamn, rubbet.path as Sökväg FROM rubbet WHERE rubbet.ortnamn like '%" + searchTextBox.Text + "%' and rubbet.harad like '" + DropDownList1.SelectedValue + "' and rubbet.socken like '" + DropDownList2.SelectedValue + "' and rubbet.ovrigt like '" + ovrigtRadioButtonList.SelectedValue + "' group by Bebyggelsenamn ORDER BY '" + sorteraDropDownList.SelectedValue + "' " + ordning + "; The query works just fine and runs smoothly. I only have one problem. If a user types for example monkey in the 'searchTextBox' the database finds all the instances of monkey, counts them and presents one line that states: Monkey, 138 instances, bla bla bla my problem is with the Min aggregate function. It selects the lowest rubbet.artal for Monkey but I want rubbet.belaggsform to get the data from the same row as Min(rubbet.artal) gets the data from. As it is now, rubbet.belaggsform selects its data from the row with the lowest primary key. For example the result could look like the following: Holmagården, 127, , 1873 when it should say: Holmagården, 127, Holmagaard, 1873 I'm only presenting the columns above, the rest of them are for creating links and what not. I guess I should write a sub query of some kind to pick the correct rubbet.belaggsform that corresponds to MIN(rubbet.artal) together with the other factors but I just can't get it to work. Help me out here please.
Hi, Situation: I have a web application that is running on a server. IT has told me that the application I developed is taking up enormous amount of ram. It seems that the amount of ram that is taken up, is slowly increasing. About 10 megs per hour (memory leak). Furthermore, he has informed me that the ram is taken up by the sql. My senior developer told me that I probably have sqlconnections open that are not closed. I have checked through the application and it seems they are all closed properly. But I may have missed some, as the application is pretty big. Questions: 1. Is there an application or piece of code that can monitor how many sql connections I have open during runtime? 2. Could there be any other common causes to such a kind of memory leak. Any help with this matter would be very much appreciated. Thank you for your time. Sincerely, Jeff
Hi everybody.I'm having difficulties with a button handler I put together from a few examples around the internet.Here's my code: <script runat="server"> Sub Add_To_Cart(ByVal Src As Object, ByVal Args As EventArgs) Dim FVArtikel_id As Label = FormViewDisplay.FindControl("Artikel_idLabel") Dim FVArtikel_naam As Label = FormViewDisplay.FindControl("Artikel_naamLabel") Dim FVArtikel_prijs As Label = FormViewDisplay.FindControl("Artikel_prijsLabel") Dim DBConnection As OleDbConnection Dim DBCommand As OleDbCommand Dim SQLString As String Dim SQLAddString As String If Not Session("sid") Is Nothing Then DBConnection = New OleDbConnection( _ "Provider=Microsoft.Jet.OLEDB.4.0;" & _ "Data Source=C:Documents and SettingsAdministratorBureaublad2ehandslego.nldatadb.mdb") DBConnection.Open() SQLString = "SELECT Count(*) FROM Orders WHERE sid = '" & CType(Session("sid"), String) & "' AND Artikel_id = '" & FVArtikel_id.Text & "'" DBCommand = New OleDbCommand(SQLString, DBConnection) DBCommand.Parameters.AddWithValue("@sid", Session("sid")) 'string? DBCommand.Parameters.AddWithValue("@Artikel_id", FVArtikel_id.Text) 'string? If DBCommand.ExecuteScalar() = 0 Then SQLAddString = "INSERT INTO Orders (sid, Order_datum, " & _ "Artikel_id, Order_artikel, Order_prijs, Order_hoeveelheid) VALUES (" & _ "'" & Session("sid") & "', " & _ "'" & Today & "', " & _ "'" & FVArtikel_id.Text & "', " & _ "'" & FVArtikel_naam.Text & "', " & _ "'" & FVArtikel_prijs.Text & "', 1)" DBCommand = New OleDbCommand(SQLAddString, DBConnection) DBCommand.Parameters.AddWithValue("@sid", Session("sid")) 'string? DBCommand.Parameters.AddWithValue("@Artikel_id", FVArtikel_id.Text) 'string? DBCommand.Parameters.AddWithValue("@Artikel_naam", FVArtikel_naam.Text) DBCommand.Parameters.AddWithValue("@Artikel_prijs", FVArtikel_prijs.Text) 'string? DBCommand.ExecuteNonQuery() End If DBConnection.Close() Src.Text = "Item Added" Src.ForeColor = Color.FromName("#990000") Src.BackColor = Color.FromName("#E0E0E0") Src.Font.Bold = True End If End Sub</script> I'm not getting any errors, it seems to me that i'm not getting a 'sid' value passed along but i don't know what to do about it.I've also already tried step debugging. This is my last resort. I hope you can help me.
I have a database with a dozen or so tables. No table constraints. Logic is all in stored procedures.
I have several Excel spreadsheets of data to import into the database, one speadsheet to a table. Each spreadsheet has additional data(columns) that each table has no interest in and should be ignored.
I would appreciate your thoughts on methods and best practices for loading this data to the database.
I am about to investigate SQL Server 2005 Express handling of XML. I am familiar with XML and XSL conversions and it seems to me that XSL conversion of Excel data to XML gives me a lot of flexibility prior to database import for shaping the data.
In short, importing data to the database from an XML source.
I am not famliar with SQL Server's XML capability and would appreciate thoughts on this while I look into it.
And of course alternate ways that I am overlooking.
Hi, Im a Jr DBA and have been given an assignment by my lead to find information on the following. We are to migrate existing db of size 4TB to a DELL PowerEdge 2950[Mem:Up to 32GB] OS : Windows Server 2003 Std Edition X64 SP2 DB : SQL Server Enterprise Edition x64
I am to find on how to design the db to provide optimum performance,fail over and consider the growing factor of the db.
1)What would be the recommended RAID settings? 2)Placement of the tempdb ? 3)Should we do clustering and why ? 4)What Data partioning would do to help? 5)Any Other aspects to be considered for sizing db ? 6)Placement of data files and log file on separate physical disk ? 7)Indexing?
I have read many sites.I would appreaciate if someone could write suggestions and opinions based on their current db design spec or previous experience,by selecting best db design points.Thank You.
Hi -- I am fairly new to SSIS development, although I am starting to appreciate it more an more, especially since I have started getting into extending the object model. Here's my question:
I have a data flow that pulls data from any number of different delimited files with different numbers of columns. I have had no problem dealing with setting up run-time file locations and file names by using the expressions of a flat file data source, and i have been able to pretty easily deal with varying file delimiters by standardizing the files before they get into the data flow. however, I have not been able to come up with a solution that will allow my data source to discover its column info at run time, and then pass that information on to the data flow task. all i really care about is being able to properly parse the individual rows into individual column data by the flat file data source because the data flow itself is able to discover the actual data that the columns hold at run-time.
i would very much appreciate any feedback from anyone on possible solutions for this.
I have the MS SQL2000 database failed to recover at computer restart. Now the database is marked suspect. How can I manage to recover the data? Thank you.
It's arriving from ebuyer tomorrow for 32 quid. I already have aninstance of MSDE running on the laptop and ideally i would like SQLserver to be installed and use the current instance and not installany other additional services. [hope i got my terminology correcthere.] Basically all i would like is to use the Enterprise Managerwith my existing MSDE database. I was wondering if there is anything ishould be doing before I install. Should i shut down the service orleave it running for instance.Thanks for any tips,AndyB

The following is my code. What I am trying to do is find all the students a teacher as assessed during a give time. Then find out which assessment was done the most recently. After that I will then be aggregating those results. I have never written any pl/sql or T-SQL... heck I don't even know what to call it!The first sql command is doing what I want it to. I can only assume the cursor is working correctly. Any help would be greatly appreciated.BryanALTER procedure Domain@UserID numeric,@StartDate datetime,@EndDate datetime AS-- Variable DeclerationDECLARE @SessionID varchar(1000)DECLARE @EachSessionID numeric --Cursor to find all Children that the teacher has assessed for the given timeDECLARE ChildID_cursor CURSORFORSELECT DISTINCT childID FROM capsessionWHERE userid = @UserIDAND sessiondate BETWEEN @StartDate AND @EndDate-- looping through all Children to find there most recent assessment.OPEN ChildID_cursorDECLARE @ChildID numeric FETCH NEXT FROM ChildID_cursor INTO @ChildIDWHILE (@@FETCH_STATUS <> -1)BEGIN IF (@@FETCH_STATUS <> -2) BEGIN DECLARE SessionID_cursor CURSOR FOR SELECT TOP 1 CAPSessionID FROM CapSession WHERE (ChildID = @ChildID) AND (SessionDate BETWEEN @StartDate AND @EndDate) ORDER BY SessionDate DESC END FETCH NEXT FROM ChildID_cursor INTO @ChildIDENDCLOSE ChildID_cursor OPEN SessionID_cursorFETCH NEXT FROM SessionID_cursor into @EachSessionID SET @SessionID = ''WHILE (@@FETCH_STATUS <> -1)BEGIN IF (@@FETCH_STATUS <> -2) BEGIN SET @SessionID = @SessionID + @EachSessionID+ ',' END FETCH NEXT FROM ChildID_cursor INTO @ChildIDENDCLOSE SessionID_cursorRETURN @EachSessionID
Hi, I wanna know if one has to undergo the 'sql video tutorials' on this website before trying to understand data access tutorials, again on this site. Are the two related by any chance. Also I am not able to find the customer database files he has created in tutorial # 5, dumb to ask, but what to do?,...so anyone willing to shed light!!!
as you might have seen, I'm a total newbie to this Site and M$ SQL. I browsed the forum to see if there are already matching answers to my question, with no success.
My question: As a MySQL & PHP user I ask myself if there is a possibility to use M$ SQL the way I use MySQL and PHP!? Is there a way to generate dynamic websites with M$ SQL 2000 and a webserver running PHP sources? A brief yes or no would really help me, if you have any links or resources on this topic, I'd be glad to hear about it.
I get the error "General SQL Error" when reading or writing to a memo field in Sql Server through a frontend build in Delphi 4. I'm Using the latest BDE. I have recently installed this onto a NT enviroment in the same manner as my own enviroment but get the error message above.
On my own enviroment and a friends enviroment I do not get any errors.
Can someone please give me some help on this or a direction to run in ?
Hi, folks. I've a production SQL machine with more than 20 users making transactions 24 hrs in 6 days a week. I've only Sunday for maintenance. The server has fixed 2 GB RAM allocation for SQL. Is it good to Restart SQL ( or machine) to clear the Buffer-Cache( or is it good to keep the cache) .... :rolleyes:
Maximum Number of rows allowed in sql server 2005 tables ? Maximum Number of columns allowed in sql server 2005 tables ? What are all the built in string functions can be allowed for 'TEXT' DataType in sql server 2005?
Before I go into specifics, this is my problem. I've have a tablethat gets updated with large amounts of data on a monthly basis.Sometimes (rarely) identical rows of data are on one months import thatalready exist from the previous month. I can identify these rows from acombination of two fields (sampleID and testname).My question is this. Would it be an appropriate 'fix' if I created anew 'formula' field on the table comprising of a concatentation ofthese two fields and then made that an index field (no duplicates)? Myguess would be that if we then tried to import a record with a sampleIDand testname that already existed, then the import for that recordwould simply fail.Would this work? Is there a better way? My background is more withAccess so apologies if I'm not using the right terminology.Simon Harris

New to using databases that are NOT Access. New to MS SQL Server.

I am currently upgrading my companies database from 6.5 to 2000. Including the replication. I am curious about something. Currently we are using the commands in 6.5 to do the replication instead of stored procedures. (except for one table that requires custome filters). When I reestablished replication on 2000, the default is to create stored procs on the subscribers to hande the replication. (sp_MSins_tablename). My question whether anybody knows why it defaults to using sp's? Is there a reason or is that just the way it is. I want to know if using sp's is better than just sing the commands before I change my setup.
Can someone please answer the following questions:
1) Am I correct that SSRS 2005 can access a remote data source on SQL Server 2000? (this one I'm pretty sure about). I'm also trying to determine whether I can move up to SSRS 2008 when it is released and keep running all the same report types against SQL 2000.
2) Where is the bulk of the reporting services calculations performed (e.g. NOT the database query itself)? The Reporter Server? Or the Reporter Server Database?
3) Is it advisable to have the Report Server and Report Server Database on the same server? How do people typically handle this?
4) Is it advisable to have the Report Server and the Datasource database on the same server?
