I have used Base SAS for analysis for a while and it was really great.. everything is easy just with a simple command.. I am sure it's not the same in SQL Server but I need some help on how to start with the following:
I have a field called call_country and another field called call_minute. Each call will be saved with the destination country and the total number of minutes..
and I want to run a query to see what are the TOP frequent destinations in this format:
select dssid,cpt,count(*) from enc_vis_cpt group by dssid,cpt will give me the cpt's and their frequency for each dssid.
dssid cpt count SPINAL CORD INJURY 9934120 AMB SURGERY EVAL BY NON-MD 622703 PSYCHOSOCIAL REHAB - GROUP 993414 SPINAL CORD INJURY 983419 AMB SURGERY EVAL BY NON-MD 6327031 PSYCHOSOCIAL REHAB - GROUP 9734114 SPINAL CORD INJURY 9934280 AMB SURGERY EVAL BY NON-MD 6227353 PSYCHOSOCIAL REHAB - GROUP 9934524
How do I limit the output to just display the 10 most frequent cpt's for each dssid. Thank you...
Hello all I'm not sure if this is anything to be concerned about, but I'd appreciate some input. I've created an alert that invokes a log backup scheduled job to start if one of the production database log becomes over 80% full. I've noticed that the log gets backed up every couple of minutes- sometimes even more frequently- while a series of scheduled jobs are in the process of execution. Otherwise, it runs and backs up the log every hour as scheduled. I've also noticed that some of the jobs are taking longer to complete (they've been running for about 6 months now). Each job truncates the table that it populates with data, so I'm not sure what the cause of the delay is. It doesn't look like there is any fragmentation. Am I missing anything? Thanks
There must be a way to do this simply. We're running SQL Server 2000. I'm looking for some generic SQL statement that I can apply.
If I have a table with a person column and a location column and multiple records for the same person / locatioin combination, how do I select the person with the location they most frequently visited? Say George visits Mexico 5 times, and the Bahamas twice and costa rica once. I would have 8 records in my table for George. The data looks something like this:
I have a reviews table where all reviews are submitted. On the main page I want to display the 10 most reviewed products. I have a Product_ID column in this table which identifys the product. How can i write a query which will select the product_ID of records which have the most frequent product_ID's?
I came up with something like this: "Select Top 10 Product_ID, COUNT(*) AS Occurances FROM reviews GROUP BY Product_ID ORDER BY occurances DESC"
But it does not work.?? It says "Declaration expected" as error
We have 7 databases mirrored on two servers which are mirroring partners. 3 of the 7 databases are live on server1 and mirrored on server2; and the remaining 4 databases are live on server2 and mirrored on server1. The data is exposed through .NET Widows Application.
The configurations of the servers are as follows.
System: Microsoft Windows Server 2003 R2
Standard x64 Edition
Service Pack 2
Computer: Intel(R) Xeon (R) CPU
5130 @ 2.00 GHz
2.00 GHz, 32.0 GB of RAM
SQL Version: Microsoft SQL Server 2005 - 9.00.3175.00 (X64) Jun 14 2007 11:45:39
Copyright (c) 1988-2005 Microsoft Corporation Enterprise Evaluation Edition (64-bit)
on Windows NT 5.2 (Build 3790: Service Pack 2)
Problem:
The databases for no apparent reason keep randomly failing over to one server quite frequently. At least twice a day. There is no pattern associated for me to make out as to why this is happening.
My Questions:
1. Is it a good practice to divide the databases on each server, the way it is now? Or should all the databases be kept on one server and mirrored on other all the time?
2. From the above mentioned scenario, do you find the reason for database to 'failing over' so frequently? Could the Win Application which is used to expose the data be responsible for the failovers?
3. What steps can be taken to check for the reason which is causing the databases to failover? Alternatively and most importantly, how can I this problem of 'Databases Failing over randomly' be solved?
What function(s) can be used to find the mode of data? I have a column that is populated with codes and I'd like to summarize the data by the code that occurs the most frequently. Any help is appreciated!!
How can I make a statement that will return the 10 most frequently occuring values in a column?
I have no idea if that is even possible, if you have an idea on how I could do that I would really appreciate it.
Im trying to make a page that would show some statistics on a table I have.
Im also trying to make something that would show the count of the number of records inserted in the last 24 hours, week, month, year etc. The table has a column called "DateInserted" as SmallDate, right now i can use a Where DateInserted > '20080310' to get the count, but its not dynamic, is there anyone to merge all these results into one row with each column being a diffrent time period?
I know this a lot of questions, but I would really appreciate any pointers.
we have a handful of developers and each of us are responsible for laying out and creating our own database backends. This often leads to inconsistencies in table and column structures.One obvious situation that comes up often is whether or not the other developers are building in history into their primary tables, using history/archive tables or (usually in cases of helper tables) no historical data at all.
My thought on how to alleviate this a little was to suggest that we all build a IS_DELETED computed column into our tables so that someone else trying to work with their data doesn't have to play the guessing game. In most cases, this column would just be running date comparisons on an Expiration Date and either checking to see if it's in the future (usually 12/31/9999) or NULL.
I have read that computed columns can be a performance hit if used/returned unnecessarily but is that also the case on fields where their main use would be filtering? It just seems that the calculation that the computed column is doing would be necessary for the WHERE anywhere so it seems like a wash ... and worth the benefit of not having to decipher someone else's work.
I am working on a text mining application wherein I need to detect unusual/anomalous sentences in text. Certain sentences, that I know occur very frequently, are given a likelihood of 0.2 by PredictCaseLikelihood. Other sentences that are just as frequent get a much higher likelihood (>0.9). I am using the NORMALIZED option. The only significant difference between these sentences is their length. The one with the lower likelihood has only 2 words in it, whereas the one with the higher likelihood has more than 10 words. The problem is that the shorter sentences end up being interpreted as anomalous, when in fact they are'nt. Any suggestions?
I am constantly getting this error message in the Application log after installing SQL 2005 last night followed by SP1 (say 5 times a minutes). See below:

My server is a dual AMD x64 2.19 GHz with 8 GB RAM running under Windows Server 2003 Enterprise Edition with service pack 1 installed. We have SQL 2000 32-bit Enterprise installed in the default instance. AWE is enabled using Dynamically configured SQL Server memory with 6215 MB minimum memory and 6656 maximum memory settings.
I have now installed, side-by-side, SQL Server 2005 Enterprise Edition in a separate named instance. Everything is running fine but I believe SQL Server2005 could run faster and need to ensure I am giving it plenty of resources. I realize AWE is not needed with SQL Server 2005 and I have seen suggestions to grant the SQL Server account the 'lock pages in memory' rights. This box only runs the SQL 2000 and SQL 2005 server databases and I would like to ensure, if possible, that each is splitting the available memory equally, at least until we can retire SQL Server 2000 next year. Any suggestions?
We have an old machine which holds SQL server 2000 database. We need to migrate a whole database to a new machine which has SQL server 2005.
When we tried to move whole database using Import and Export Wizard, only tables can be selected to import/export. However we want to import/export the whole database, including tables, stored procedure, view, etc. Which tool should we use?

When I proposed start to use SQL Server 2005 for new VS 2005 web sites, one of my co-workers responded that we will update the old SQL Server 2000 databases to SQL Server 2005 when we are ready to use 2005 SQL Server.
Questions: 1. Any expected problems to upgrade old 2000 databases to new 2005 SQL Server? 2. I have installed both 2005/Management Studio Express and 2000/Enterprise Manager in my PC. Any expected problems when running both 2000 and 2005 SQL Server at the same database server? 3. What is the best configuration for running SQL Server 2005 when we have old 2000 databases? Upgade or not upgrade?

Hi, I am having a problem connecting my .net applications from the application server to the database server. When I run the application from my windows xp (sp2) box it works fine. When I try to connect via SQL Management Studio to the database server from the application server I get the same error. Here is the error: System.Data.SqlClient.SqlException: 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: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) Here is the Environment: App Server: Windows Server 2003 Standard Edition Inside Company's Firewall/ Network Database Server: Windows Server 2000 Advanced Edition SQL Server 2000 SP4 Remote Connections to the Server is checked Enable Protocols: Named Pipes & TCP/IP TCP/IP Port: 1402 (I don't know why it isn't the default of 1433) The db server is sitting out side the Company's firewall (don't ask me why). I can access it fine from inside the firewall on my XP box but not from windows server 2003. There is a web server outside the our network that also connects to the db server with no problem and that is running Windows Server 2003 Web Edition. I can ping the db server from the app server using the IP address. I tried using the IP address and the port 1402 in my connection string but that didn't work from any machine (XP and Server). I imagine the issue is somehow related to the company's firewall but why would it only block Windows Server 2003 and not XP? What do I tell the network admin to change? Any help would be appreciated. Thanks, Oran
if you can restore a database to Server B using Server A as the service. Meaning we would issue the command on Server A but somehow point to Server B as where we want the restore to happen.
The backup file would be in a location independent of both servers.
Dear all,On Win2000 server with SP3, I am trying to access a SQL Server 7.0database, "TestDB", from VB6 via a SQL Server ODBC system DSN using ADO2.7. In SQL Server Enterprise Manager, there is a login named "Tester".In its property window, NO "Server Roles" was assigned but its"Database Access" was set to "TestDB". This login was also made as theuser of "TestDB" with "public", "db_datareader" and "db_datawriter"selected as its "Database role membership". All the tables I am tryingto access in "TestDB" were created under "Tester".My code is like:Set conn = New ADODB.Connectionconn.Open "DSN=TestDSN;UID=Tester;PWD=test"Set cmd = New ADODB.Commandcmd.ActiveConnection = conncmd.CommandText = SQLset rs = cmd.Execute()If I set the SQL to something like "SELECT * FROM tbl_test", I alwaysget an error of "-2147217865" saying "[Microsoft][ODBC SQL ServerDriver][SQL Server] Invalid object name tbl_test". If I set the SQL to"SELECT * FROM Tester.tbl_test", everything runs properly. Could anyoneplease kindly advise why the first SQL is not working? Or in otherwords, why must I prefix the table name with its owner while the DBconnection is already made under that owner name? Thanks in advance.Tracy
When I try to migrate a database on a SQL Server 2000 server to a SQL Server 2005 server with the Copy Database Wizard of the SQL Server Management Studio, I'm confronted with the following problem;
Performing operation...
- Add log for package (Success) - Add task for transferring database objects (Success) - Create package (Success) - Start SQL Server Agent Job (Success) - Execute SQL Server Agent Job (Error) Messages * The job failed. Check the event log on the destination server for details. (Copy Database Wizard)
When I take a look at 'Event viewer' on the SQL 2005 server, the following error is displayed;
InnerException-->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: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
I already enabled the MSSQLSERVER network configuration protocols (TCP/IP and Named Pipes ).
My site works fine in VWD2008 express, but I get this error when I try to use it on my live website. 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. According to this article: http://support.microsoft.com/kb/914277 I am supposed to:
1. Click Start, point to Programs, point to Microsoft SQL Server 2005, point to Configuration Tools, and then click SQL Server Surface Area Configuration. Ok, there is no such program in this folder. The only thing in there is "SQL Server Error and Usage Reporting"... The other thing I am greatly concerned with is this: All is want is for my webpages to be able to access my database for user authentication. I DO NOT want to grant the internet rights to remote connect to my database.
Hi All, Please some one help me... I have to insert a csv into one table in sql server. But the problem is the file is in one server and SQL SERVER 2005 is in other server.. how do i insert the file.... please help me.....
Hi Guys, I have had SQL Server Express and Sql Server Management Studio Express installed on my machine for some time and recently tried to install a trial of SQL Server 2005 as well. (Yes, I'm migrating from Visual Studio Express to Visual Studio Professional, just as in tended!) Everything went fine except that nothing seemed to be installed. I searched in all the obvious places - both on the Start/Programs menu and on the hard-drive: nothing. A check under Add/Remove Programs showed that Sql Server 2005 Express was installed, but called SQL Server 2005. So after a number of retries in which the install program kept saying that there was nothing to install, I selected every option under Advanced in the intall process. This resulted in stuff being installed and I now have SQL Server 2005 running on my machine, but no SQL Server Manager icon. My questions are:
Where can I find the SQL Server Manager executeable? Has anyone installed SQL Server Express, SQL Server Mangement Studio Express, SQL Server 2005 and SQL Server Management Studio on a single machine successfully? If so, what order did you install them in? (I'm planning on uninstalling everything SXQL Server related and starting again.) Thanks very much for your help. Regards Gary
Hi,Is it possible to install on a Windows server 2003,SQL SERVER 2000 in the folowing configuration :SQL server 7.0 as a default InstanceandSQL server 2000 as a named instance.Thanks for your answer.
Hi I have created a linked server from SQL Server 2005 (SP 1) to SQL Service 2000 (SP 4) with a sql server login that is available on both servers but with different passwords and permissions.
I am getting the following error while accessing the linked server in management studio based on the scenario given below ;
------ Error Message Starts OLE DB provider "SQLNCLI" for linked server "(SQL Server 2000 instance name)" returned message "Communication link failure". Msg 10054, Level 16, State 1, Line 0 TCP Provider: An existing connection was forcibly closed by the remote host. Msg 18456, Level 14, State 1, Line 0 Login failed for user 'abc'. ------ Error Message Ends
Consider login name is abc. Now this login abc has sysadmin rights on sql server 2005. The same login abc has only db_datareader rights on sql server 2000 on just one database and is not associated with any fixed server role.
I have configured the linked server using the following options; 1. I have tried impersonating login from SQL Server 2005 to SQL Server 2000 . 2. I have also tried specifying remote login / password option.
Anyone having any idea, would be of great help. Regards, Salman Shehbaz.

I have an intranet environment consists of two servers:
- An application server windows 2003 server with 64-bit server Sharepoint 2007 SP1 (Standard version for search) - A database server windows 2003 server with 64-bit SQL Server 2005 SP2 64-bit (Standard - 9.0.3054)
It happens regularly that the database server crash (frozen black screen) while the application server indexes (crawl) the content of the intranet site based on sharepoint. There is no alert / error in the observer of events, nor in the sql logs.
The crash is uncertain: dice once all goes well, soon after that crash. When i set the parameter search service (service management research), I can define a regulatory impact of the robot to change the number of documents at the same time : "Request 2 documents at the same time, the crash is more rare, "ask 64 documents at a time, the crash is more common.
My Intranet under sharepoint is composed of a collection site with a dozen sub-sites. There are 3 large library of PDF document. All done in the 4 go in terms of volume.
My problem for about 3-4 months. (Maybe more. Before, indexing was not yet in place).
Can I connect from a SQL Server 2005 database to a SQL Server 2000 database, without establishing a linked server connection.
I need to fire a SELECT query on a SQL Server 2000 database, but don't want to add it as a linked server. Is there any way I can do this or its not possible??
