I'm sure this has been a topic in the past. I would like to build a fact sheet about each one and do a compairison. Are there any articles/links/resources out there that speak to this issue?
There is now a NEW SQL discussion Group currently being tested; http://www.baysignia.com/discussions/discussions.xml Try it out and send comments to faq@baysignia.com
CREATE TABLE [dbo].[Audit] ( [id] [int] identity (1,1) NOT NULL , [col1] [char] (10) NOT NULL , [col2] [char] (15) NOT NULL , [col3] [int] NOT NULL , [col4] [varchar] (50) NOT NULL , [col5] [datetime] NOT NULL , [col6] [varchar] (4000) NULL , [col7] [char] (3) NULL ) GO
This table grows to about 40 million rows during the course of the month. The table has a clustered index on the id field and a non clustered index on the col2 and col3. The id column is not used in queries. At the moment we run weekly dbcc reindexes on all the indexes. We are running into a space issue on the reindex of the clustered index (copying the whole table out , ordering etc) and are considering dropping the index or changing to a non clustered index. (The DBCC utility that we have built will only rebuilt all the indexes or none at all.)
I feel this is not a good idea and know my reasons. I would like some input as to why this might prove a bad idea.
Will it increase page splitting? Will the table performance be impacted even if the queries are not specifically using the clustered index?
I'm creating a discussion forum for my website, using Sql Server 2000. I need to display 'Number of threads', 'Number of posts', 'Last post by' (username/id and date) for each forum, and 'Number of replies' and 'Last post by' (username/id and date) for each thread.Here are a couple of ideas I have come up with to solve this problem:1) Poll the database (using a stored procedure that returns the number I'm looking for) for each forum when I loop all the fourms. - I suspect this approach isn't optimal, since it creates more traffic to the database.2) Have fields in my Forum and ForumPost tables for 'Number of threads' and so on. Now, create triggers that updates these fields every time a post is made. - I guess this would be much more effective than the first apporach, since everything is done on the database server directly.Are there any other ways that are better? Please advice! Thanks a bunch for any help!
OK, I`ve been researching the use of the TEXT datatype all day and would like opinions on what I`ve found.
First, a little background. I have been tasked with writing an ASP application to handle the display of FAQs for a company`s products. I would like to store all info in a table much like
faqID int question TEXT answer TEXT
Simple enough, right? I then tried to create a stored procedure to add a new FAQ and all hell broke loose. ASP would not pass anything larger than 255 chars to the stored procedure.
I read in the "ADO and SQL Server Developer`s Guide" from Microsoft about using varchar datatypes of 255 chars (instead of TEXT) and chunking large text up to fit in these smaller datatypes. This seems like a lot of work.
I also read in "Inside SQL Server 6.5" that "The text datatype is sometimes awkward to work with. Many functions don`t operate against text, stored procedures are limited in what they can do with text, and some tools don`t deal with it well." (page 632). This statement concerns me greatly. How are stored procedures limited in dealing with TEXT? Do the standard SQL UPDATE and INSERT commands work or must READTEXT and UPDATETEXT be used instead?
I guess my question is, what is the best way to accomplish this? I have a feeling that others have had to do this before. Is SQL Server not meant to handle large textual objects? Is chunking the best way to go? Will version 7.0 handle this scenario better?
I would like to hear your thoughts on a philosophy I adhere to.
As a rule of thumb I've always preached that Unique Indexes are for linking tables and Primary Keys are used to ensure that records aren't duplicated. I’ve embraced this philosophy for a couple reasons, the main one being that I don’t have to create numerous foreign key fields in the foreign key table.
However I’ve done most of my programming in Access and am now in need of something more robust (SQL Server v7) and I’m wondering if I need to reconsider.
I do also have a how to question; that being is it possible to create a table join on a unique index in SQL Server v7 and if so how? I would like to have an Auto Number / Auto Incremented / Unique Identifier field in the Primary Key table that links to a numeric field in the Foreign Key table.
I have been doing relational database forever(or a long time) and have been intruduces to a team that uses a highly normalized database(propietary) to manage workflow.
We are capturing data in an AUDIT Trail EAV format.(500 million rows)
It is my task to build this into a data warehouse for reporting and I need to have with my team a relational database discussion. The relational database knowledge on this team is DB2 based, IDMS, and other past evolutions.
The common processes used are recieve a flat file and process this file sequentially using C# or VB doing lookups of other databse tables and writing out another flat file to be converted in XML for load to the propritary system.
My goal is to attempt to introduce new design concepts to my team and these are some talking points that I have come up with for a lunch and learn session.
can anyone else add to this list I don't want to get into a deep discussion about 3rd NF, Star Schemas vs Snowflake, etc.. I want to keep is informational and light to eliceit discussion and relat it back to older technologies.
some of the topics we can discuss are: Why the data warehouse Real-time tables what needs to stay in prod What is going to happen to reporting database Interaction between database on the same cluster/server Interaction between databases on different servers (linked servers not allowed) Set processing as opposed to cursor processing. Table types EAV Type1 Type2 Fact Dimensions Code
I'm a DB teacher in a University. Planning and developing SQL exercises for my students I found a "tricky" or extrange sql exercise.
The sql exercise using Northwind DB reads as follows: "Wich is the total amount of the freight that corresponds to all orders containing products of seafood category ?"
The first sql code that comes to my mind was:
select sum(freight) from orders o, "order details" d, products p, categories c where o.orderid=d.orderid and d.productid=p.productid and p.categoryid=c.categoryid and categoryname='seafood'
This is equivalent code constructed with Query constructor in Enterprise Manager: SELECT SUM(dbo.Orders.Freight) AS Expr1 FROM dbo.Orders INNER JOIN dbo.[Order Details] ON dbo.Orders.OrderID = dbo.[Order Details].OrderID INNER JOIN dbo.Products ON dbo.[Order Details].ProductID = dbo.Products.ProductID INNER JOIN dbo.Categories ON dbo.Products.CategoryID = dbo.Categories.CategoryID WHERE (dbo.Categories.CategoryName = N'seafood')
These 2 equivalent queries output 27722.9600 as result, but the correct result (total freight) is 23791.1400.
Did you also think (as I did) that the exposed code is correct?
Now I know the correct sql code that gives the corect answer and also the explanation why the code exposed fails, but before share it under your posible request, want to know your tech comments about this exercise in order to know if this particular exercise is "tricky" (make people to fail) or is my total fault and need to review my strategies of applying/constructing sql (and teaching).
I am about to prepare a paper concerning the field of real-time data mining. Real-time here means the process of incremental training of an existing model as soon as the data arrives.
There is a number of papers introducing algorithms for incremental association analysis, incremental clustering etc. Stream mining Ãs a field which is closely related to that. The main reason for the implementation of incremental algorithms is a) the large amount of data to be mined and b) the high rate of new data that is evolving every day.
Using classical batch mining algorithms, models that are outdated for some reason, would have to be re-trained, which could be very time consuming for billions of records. And once the training is completed, the training would have to be restarted once again because a bulk of new data has been arrived.
The question that I would like to discuss now is: For what real world applications would it be a meaningful or even essential to use real-time training of models?
Two main reasons could determine the answer to that question:
You just want to incorporate new data into existing models in order to increase the prediction accuracy of your model or Your underlying data is subject to more or less massive changes (also refered to as concept drift) and you want to adapt your mining model continuously to that reality.
I'm looking for some examples or ideas where one of these cases apply and it would be a good idea to have incremental mining algorithms involved.
I'm looking forward to inspiring some discussion on that issue.
I have recently upgraded to SQL2014 on Win2012. The Access front end program works fine.
But, previously created Excel reports with built in MS Queries now fail with the above error for users with MS 2013. The queries still work for users still using MS 2007.Â
I also cannot create any new queries and get the same error message. If I log on as myself on the domain to another PC with 2007 installed it works fine, so I don't think it is anything to do with AD groups or permissions.
I've been developing desktop client-server and web apps and have used Access and SQL Server Standard most of the time. I'm looking into using SQL CE, and had a few questions that I can't seem to get a clear picture on:
- The documentation for CE says that it supports 256 simultaneous connections and offers the Isolation levels, Transactions, Locking, etc with a 4GB DB. But most people say that CE is strictly a single-user DB and should not be used as a DB Server. Could CE be extended for use as a multi-user DB Server by creating a custom server such as a .NET Remoting Server hosted through a Windows Service (or any other custom host) on a machine whereby the CE DB would run in-process with this server on the machine which would then be accessed by multiple users from multiple machines?? Clients PCs -> Server PC hosting Remoting Service -> ADO.NET -> SQL CE
- and further more can we use Enterprise Services (Serviced Components) to connect to SQL CE and further extend this model to offer a pure high-quality DB Server? Clients PCs -> Server PC hosting Remoting Service -> Enterprise Services -> ADO.NET -> SQL CE
Seems quite doable to me, but I may be wrong..please let me know either ways
When i am trying to start our hospital software based on SQL server 2000, it shows Following Error.Search Condition is not valid, (DBNETLIB) Connection Open (connect()).  SQL server does not exist or excess denied. Due to Fetch data.I run our software in Windows 8.1, while it smothly runs in previous version of Windows XP and 7.
Hello allWould it be possible to migrate the MS Access 2000 to MS SQL Server2000?My application is using MS Access 2000 as database and as userinterface such as forms. Now, I want to migrate the backend databasefrom MS Access 2000 to MS SQL Server 2000. However, I want to keep theMS Access 2000 interface. Would it be possible?If I migrate the MS Access to SQL Server, would the queries, back-endVBA, macro, tables and forms be affected? Do I need to change the MSAccess data type to SQL server supported data type?Which tool I can use to do the migration? Upsizing wizard or exportingthe Access database and then importing it to the SQL server?Thanks in advanceCheersBon
I am trying to connect through ODBC connectivity, but it will not allow me to do so. I have investigated this matter. It leads me back to the server, because as I was configuring my client side database. It kept asking for the DSN(datasource name), but I was unable to choose one because there wasn't one to choose. Which is my current dilemma, How can I do this and have it available to choose from the server to satisfy the Access database?
I went to the domain where the software resides but I don't know what steps to take? I also found an interesting piece on microsoft about Kerberos, but I can't follow along according to the instructions it has. I have Access 2003 & SQL SERVER 2005, HELP...!
Basically, this is right off the heels of the install. I setup the server without the connectivity, but it is running the current configuration.
Hi, Can anyone tell me how i can access an application or open tables in MS sql server that are in MS Access. Its urgent and any help will be appriaciated.
We are using Win2k3 R2 with SQL 2000 in a domain environment.
Is it possible to create a domain group to grant admin level and user level access to SQL2000/2005 without giving users server admin or domain admin access?
It has always been my impression that to have admin access to SQL that you had to at least had admin level access on the server.
I've recently started working with a public sector organisation who have 4 clustered sql instances that has 80% of it's db mirrored.
Looking at the transaction log - it seems that a transaction log backup is a good idea as the log is 4x larger than the data file.But I'm not allowed access to the physical server to check onto which drive I can create the trn. No RDP, no vmware - let's be honest I'm not even allowed to launch cmd line Also the Server Manager informs me "We will need to carefully look at database backups if you guys want to start doing these backups on box, as that will break our off box backup routine (it will screw the transaction chain)."
I don't understand how backing up the transaction log could break the "transaction chain"?
I'm trying to link SQL Server 2000 sp3 to SQL 2005 64 bit. I keep getting Error 17 sql server does not exist or access denined. I tried adding remote user mapping and chaning the linked server properties to "Be made using this security context" without any success. Any help is appreciated.
I am receiving the following error when starting a program called ShelbySystems that is supposed to connect to a local database. I don't think this is a security issue but I don't know much about SQL server either so...
  DIAG [08001] [Microsoft][ODBC SQL Server Driver][Shared Memory]SQL Server does not exist or access denied. (17)   DIAG [01000] [Microsoft][ODBC SQL Server Driver][Shared Memory]ConnectionOpen (Connect()). (2)
System Info: Windows 10Â Home -Â upgrade from 8 64 bit SQL server 2012 Express SQL Backwards compatibility 2005 64 bit ShelbySystems software v5.4
I am including the trace log in case it is useful.
when I was sending 50 simultaneous connections to the web services, I got these 2 errors: - "1[Microsoft][ODBC SQL Server Driver][DBNETLIB]SQL Server does not exist or access denied. "
- "An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: TCP Provider, error: 0 - A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.)"
Everything worked fine if I ran 10 simultaneous connections. I am using Microsoft ACT to load test the web service. The database is SQL Server 2000. Any idea about why this is happening?
I am running Windows 2003 Standard edition with IIS and SQL 2000 SP3a installed on it.
The web clients use ASP pages which use DSN to connect to SQL 2000 database. It has been working fine since last 1.5 years except 2 days ago when I faced this error suddenly on server:
I checked the error logs of SQL server and didn't find anything. Only entries were that the SQL is starting database, ports and IPs on which it is listening etc. The usual stuff. No errors in starting.
The SQL Agent log showed following errors:
2004-11-30 04:45:33 - ! [298] SQLServer Error: 2, ConnectionOpen (Connect()). [SQLSTATE 01000] 2004-11-30 04:45:33 - ! [382] Logon to server '(local)' failed (JobManager) 2004-11-30 04:45:36 - ! [298] SQLServer Error: 17, SQL Server does not exist or access denied. [SQLSTATE
I don't understand what was the problem. It first occured when nothing on server was changed, next it occured 30-32 hours later, and still now it hasn't happened again.
I want to import the data from specific Access Database and Table to SQL Server, using SQL Script. I am trying to implement the solution as given in this link. URL....Here is the code that I have tried -
sp_configure 'show advanced options', 1; GO RECONFIGURE; GO sp_configure 'Ad Hoc Distributed Queries', 1; GO
[code]...
The access database file path is - 'C:SQL ProjectTestDB1001.mdb'.The Table from which I want to import the data is - [Table1001]. but when I run this script, I get this error -9 The OLE DB provider "Microsoft.ACE.OLEDB.12.0" for linked server "MSAccessConnect" reported an error. Authentication failed.
Secondly I need to make 2 more changes to the code posted above.
1.If some access database .mdb, has got password protection, then how to include the password in the script, so that one does not have to manually feed in the password during data import work.
2. How to limit the data that is to be imported from the table [Table1001] by including a WHERE Clause, like for example - SELECT * FROM [Table1001] WHERE xdate = '2015-9-16 00:00:00.000')
I just installed SQL Server Compact Edition, since I am considering using it instead of SQL Server Express for a local database in my application. The documentation mentioned that I could use SQL Server Management Studio Express to connect to the Compact Edition and create and manipulate databases.
To try to connect, I run Management Studio and bring up the "Connect to Server" dialog. Unfortunately, the pull-down list of "Server name"s does not include the SQL Server Compact Edition server. I do not know how to type in the server name manually, so I cannot connect.
To install Compact Edition, I downloaded it and ran "SQLServerCE31-EN.msi". This installed, and I assume registered, a number of DLLs in "C:Program FilesMicrosoft SQL Server Compact Editionv3.1".
Is there perhaps an additional step that I left out to complete the installation?
Might I need an upgrade to some other components? My Management Studio Version is:
- Microsoft SQL Server Management Studio Express 9.00.2047.00
I have deployed some reports on the reporting server, i have noticed that every one in the domain in which the reports are published can access the reports, except one user. when he tries to access the report he got the following error message or the blank report.
"An error occured during report processing"
"can no read the next data row for the data set dataset1".
Although this user has all the roles on the reporiting server kike browser,content manager etc.
I am receiving the following error when attempting to access reporting services... to sum things up real nice and tidy-
I get three login prompts - then the access denied response. It is almost as if it is unable to authenticate the user... anyway... here's the actual error response, I'd really appreciate any input/insight/resolution.
