Our needs are on yearly basis and on monthly basis. We're forced to keep up five years for the majority of the production tables.
In terms of years, I see three ways:
1.Create all the ranges for a FILEGROUP with a only NDF
2004, 2005, 2006 => FG1 => ONE.NDF
2.Create all the ranges for a FILEGROUP along with more than one NDF.
2004, 2005, 2006 => FG1 => ONE.NDF
TWO.NDF
3.Create each range to a FILEGROUP where there will be one NDF or (n) NDF
Hi everyone, I have successfully managed to create filegroup Function and partitioning scheme. My question is how then Next month incoming increaze 2 functions. Next will be 200812...how I made an add to the logic?
I found an example that explain me strategy...but with a fixed number of Filegroup, making the switch IN / OUT. My case necessarily the filegroup file are always on add
Thanks, Alen Italy

I want to partion a table based on the client specific id and I want these values (client id's) to be passed dynamically to the create partition function. I am not familiar with partitioning so it will be great if someone guides me (I am also reading some articles on partitioning, but it will be easier with some help)
The table I am trying to partition has like 80 million rows with four client's data as of now and will be more once we implement new clients.
I also think Partition will help, because before we load a client's data, we remove the data that is already out there (we flush previous qtr data before we insert this qtr data)
I am trying to use table partition feature from Sql Server 2005 enterprise edition.
I have Names table with columns FNAME, LNAME and DISPLAYNAME (concatenation of FNAME and LNAME) which I partitioned across 2 drives and 4 file groups based on the below criteria.
CREATE PARTITION FUNCTION pfNameRange(varchar(200)) AS RANGE RIGHT FOR VALUES ('F', 'I', 'S');
Currently there are 5 mill rows in this partitioned tables - partitioned table has clustered index on ID (identity property) and LNAME.
I also created another table with the same data without partition on the table.
When I run the following query I get the same response time of 10secs from both tables.
Names - partitoned table with clustered index on ID and Lname NameSEARCH - with no partition and no index
select * from names where lname = 'smith' select * from namesearch where lname = 'smith'
Is it safe to assume that if the data files are on San it doesnt give any advantage of table paritioning?
How can paritioning be made effective with data files on San
I have about 45000 records in a CSV file, which I am using as HTTP request parameters to query a website and store some results in a database. This is the kind of application which runs 24/7, so database grows really quickly. Every insert fires up a trigger, which has to look for some old records based on some criteria and modify the last inserted record. My client is crazy about performance on this one and suggested to move the old records into another table, which has exactly the same structure, but would serve as a historical table only (used to generate reports, statistics, etc.), whilst the original table would store only the latest rows (so no more than 45k at a given time, whereas the historical table may grow to millions of records). Is this a good idea? Having the performance in mind and the fact that there's that trigger - it has to run as quickly as possible - I might second that idea. Is it good or bad? What do you think?
I read a similar post here, which mentioned SQL Server 2005 partitioning, I might as well try this, although I never used it before.
I have a database with more 50 tables and 25 tables are having more than 10 lakhs records which includes history records.I have two data files for this database under PRIMARY FILE GROUP.Now i want to transfer these history records to some other database. I wanted to know if this kind of activity will boost the database performance?.If yes how should i configure my new database. On what factors of partitioning my performance will boost.
I have 6 tables which are very huge in row count and need to be partitioned for better manageability.
Little info: Every day, 300 Million records are inserted and 300 million records are deleted in below 7 tables. we maintain only 8 days worth of data in below tables which is the reason records which are older than 8 days are continuously deleted.
Master table which has [ID],[Timestamp] Table Name: Sample - 2,578,106
Child tables: Foreign key [ID] is common for all the tables. There is no timestamp column in child table. dbo.ConnectionDB - 1,147,578,048 dbo.ConnectionSS - 876,458,321 dbo.ConnectionRT - 118,133,857 dbo.ConnectionSample - 100,038,535 dbo.Command - 100,032,235
I would like to partition the above child tables based on the IDs that are inserted every 4 hours. Meaning, All IDs that are inserted in 4 hours window should be in a partition.
We have an existing BI/DW process that adds large chunks of data daily (~10M rows) to an existing table, as well as using Deletes to remove stale data. This scenario seems to beg for partitioning to support switching in/out data.
After lots of reading on this, I have figured out the mechanics of the switching, bit I still have some unknowns about the indexes needed to support this.
The table currently has several non-clustered indexes, including one on the partitioning column - let's call that column snapshotdate. Fortunately there are no FKs involved, and no constraints.
Most of the partitioning material I see focuses on creating a clustered PK to assist with switching. Not sure if this is actually necessary, but assume I create one using an Identity column (currently missing) plus snapshotdate.
For the other non-clustered, non-unique indexes, can I just add the snapshotdate to the end of the index? i.e. will that satisfy the switching requirement?
I mange several large databases with multiple files and filegroups. During some maintenance I was trying to remove a filegroup and its files and noticed that I was unable to. It appears that some service broker objects were created on my user defined filegroup.
Looking at the system tables I see several system tables on my user defined filegroup
SELECT o.name +'.' +i.name FROM sysobjects o inner join sysindexes i on i.id = o.id where groupid = 2
we like some of the advantages filegroups offer but wonder if the purpose is somewhat defeated if it is true that tables sitting on other filegroups still have to work with the same transaction log that the db's primary tables work with.
I'm running under Windows Server 2000 datacenter sp4 with sql server 2000 Sp4
on 16GB Ram.
I enabled the /PAE in the boot.ini file and also enabled the AWE and set the SLQ Server maximum memory to 6144.
Do I need to include the /3GB switch in the boot.ini file?
I'm a little bit confused with the article found on the site. http://support.microsoft.com/default.aspx/kb/274750
Here are the lines.
Use of the /PAE switch in the Boot.ini and the AWE enable option in SQL Server allows SQL Server 2000 to utilize more than 4 GB memory. Without the /PAE switch SQL Server can only utilize up to 3 GB of memory. or-Use of the /3GB switch in the Boot.ini file allows SQL Server 2000 to use up to 3 GB of available memory.
hi.. guys this is simple for you guys how can i make ms access to display the current date in a col.... when i go to insert a new line i how can i make it so that its allready there? i dont have to type it??????
You might just be able to save me downloading and installing SQL Server French...
I'm having localization problems with some .NET code - and I might be able to solve the problem if I know how SQL is parsed in different locales. Say my table MyTable contains a float column FloatColumn. In English, I would say SELECT * FROM MyTable WHERE FloatColumn = 2.3
If my locale was, say for argument's sake, French, would I have to write SELECT * FROM MyTable WHERE FloatColumn = 2,3 ???
Overview. Machine data is fed into DOWNTIMELOG via a Cimplicity. I do not have the ability to change the way that it goes in. It contains the time that a machine has stopped and where the stoppage has occurred. Via a web page I want to give the operator the amount of time the machine stopped. From that they will provide some more detail. As they enter time, I need to subtract what they entered from the total (DOWNTIMELOG). That is the reason I created ENTERED_TIME. [PDNTOTAL_TEMP_VAL0] hold the total time for each stoppage, [TOTTIME] is intended to hold the value that has been accounted for. [DWNCATEGORY_TEMP_VAL0] holds the category and matches up with [DWNCATEGORY]. Also, I need to match Date and Shift. The problem is that DOWNTIMELOG does not capture shift. However, 1st shift occurs between 700 and 1500, 2nd shift occurs between 1500 and 2300, 3rd shift occurs between 2300 and 700. 3rd shift presents a problem as it occurs across 2 dates. Could someone please help me with a query that provides the net between the two tables that is matched by date, shift and category? CREATE TABLE [dbo].[DOWNTIMELOG] ( [timestamp] [datetime] NOT NULL , [DWNTIMESTAMP_VAL0] [varchar] (25) NULL , [UPTIMESTAMP_VAL0] [varchar] (25) NULL , [PDNHOUR_VAL0] [int] NULL , [PDNMIN_VAL0] [int] NULL , [PDNSEC_VAL0] [int] NULL , [PDNTOTAL_TEMP_VAL0] [int] NULL , [DWNMSG_TEMP_VAL0] [int] NULL , [DWNCATEGORY_TEMP_VAL0] [varchar] (50) NULL
Where can i learn about making the sql server execute task when a certain situation happens. Like lets say make the server delete all entrys older than 40 days? Or have a entry deleted automatically when a certain situation happens like lets say it take 4 votes and a entry get deleted how do i make it do that automatically
Hello,I need to be able to replace only the first occurance of a space characterin a column.Reason being is the data in the column I am trying to replace seems to haveumpteen space characters after each entry, so a simple replace functionwill replace all the spaces after it with what I want!I have thought of RTRIM to get rid of the spaces after and then replace, Ihave also thought of CHARINDEX to find the first occurance of a space andSTUFF to replace it.I have done my homework on these functions!But I am having trouble writing such a statement,I've never written a query which would use more then one function on onecolumn you see and I am getting confused!I'll tell you what I want to do in simple stepsReplace only the first found space in a name column, but then if a name hasa middle initial that will be a problem,Replace that with a dot.then concatanate '@emailaddress;@emailaddress2' after itso when SQLServer does the select it will bring back something likejoe.bloggs@emailaddress;emailaddressBut I guess I'd also need joe.n.bloggs@emailaddress;emailaddressThe data in the column looks like this at the momentjoe bloggsBut I guess there may come a time when we havejoe n bloggs, just to complicate things!What is your advice, and how do I write a query like thisI have been playing around with it in Query Analyser but as I said I amgetting confused and need some help if you don't mindThanks a lot to all who reply :-)RegardsJayne
For example if I make a column not null the SQL Script generated. Removes all indexes, keys, etc... than creates a temp tableThan moves the data into the temp tablethen deletes the old tablerenames the temp tableRecreate all the indexes, keys, etc... Is there a structure reason for it? Like now that the DB is being alerted that the column is not null it wants to re insert all the data so it can re-organize it? Because I can just write my own script to the effect of ALTER [TABLE] [COLUMN] PARAM TYPE NOT NULLone line of script that seemingly does the exact same thing.. So I'm just curious when I change a column to non null why doesn't it just generate a simple one liner?
I have this query that calculates the next possible shipping day, based on 3 conditions:
- It has to be a workingday (WORKTIMECONTROL: 1 workingday, 0 holiday) - marked green - There might be extra days (@xdays) required by the process - marked blue - Customer wants their goods to be shipped on special days - marked red:select TOP 1 Transdate from WORKCALENDARDATE where Transdate > @startday and WORKTIMECONTROL = 1 and DATEPART(WEEKDAY,TRANSDATE)-1 in (2,4) and
[code]...
So customer 123456 accepts shipping of goods only on tuesday and thursday as in the above example "... in (2,4)". Multiple shipping days means that the Subquery returns more than one record, which gives me a headache as I don't see how to integrate this portion into my query. I tried to use the stuff function as I formally need a result that can be provided that way; but the format is incorrect as it in varchar, while an array of integer is needed.
DATEPART(WEEKDAY,TRANSDATE)-1 in (select stuff((select ',' + CAST(DELIVERYDAY as nvarchar) from CollectiveShipment where custaccount = '123456' for xml path('')),1,1,''))
This is probably for most of you a very basic question. My goal is to define in a seperate instance from application all infos related to DataSets and DataAdapters that are needed when connecting to a specific database. Why?
First, I would like to be able to have in a single instance everything needed when hooking to a SQL Server Express database and in an other everything needed when hooking to a SQL Server CE database. Then, from application, I would like to be able following a few basic configuration steps to choose from one or the other, or even both in specific cases.
Second, I want to be able to seperate Database related stuff from application so that I can re-use everything from any other application when needed.
I've read several books, articles on the subject and would like to have your opinion as several approaches were illustrated through them. What would you use for this:
how to get records using stuff keyword as above i want to query using where condition with where objid=1 and should frame output as Parking, Toll only 1 input parameter need to given.
I'm implementing merge replication between SQL CE and sql server 2005 SP2. Here is the problem I'm facing
I have dynamic filters on some tables like
Select * from table1 inner join table2
ON table1.field1 = table2.field3
and table2.flag = true
When table2 flag turns true then all the matching records in table1 should be returned to the subscriber.
But that is not happening. The filter does not return any records to the subscriber even though i see records when i run the query on the server. My take on this is the publisher thinks there is no changes on table1 so there is nothing to update. So to fix that i run dummy updates like
update table1
set [name] = [name]
where table1.field1 in
(Select field2 from table2 where flag=true)
This updates the records and the publisher updates the subscriber the first time. When i set the flag to false, it is supposed to remove the data from the subscriber but i get this error.
The merge process failed because it detected a mismatch between the replication metadata of the two replicas, such that some changes could be lost leading to non-convergence. This could be due to the subscriber not having synchronized within the retention period, or because of one of the replicas being restored to a backup older than retention period, or because of the publisher performing more aggressive cleanup on articles of type download-only and articles with partition_options = 3. (Source: MSSQL_REPL, Error number: MSSQL_REPL-2147199363) Get help: http://help/MSSQL_REPL-2147199363
The common generation watermark is invalid at this replica since it does not exist or metadata for changes not yet propagated may have been cleaned up. (Source: MSSQLServer, Error number: 21800) Get help: http://help/21800
I have no idea whats going on. Any clues, anyone? Thanks for your help.
I have a project. Originally when I created this project, I called it "Project_A", (and I did not create a solution directory).
Doing this created a folder called "Project_A" with the following files within it. I guess these are meta data files and I shouldnt be messing around with them. Anyway, I see
(1) Package.dtsx (The default package that gets created with a new project) (2) Project_A.database (3) Project_A.dtproj (4) Project_A.dtproj.user (5) Project_A.sln (6) Project_A.suo
When I rename my project in the Solution Explorer to "Project_B", the following happens in my folder.
Everything remains the same except Project_A.dtproj gets renamed to Project_B.dtproj and a new file called Project_B.dtproj.user gets created.
Now, my questions.
Question 1: What if I wanted my folder to have the same name as my project? Can I just change the folder name in Windows Explorer without having any ill-behaviors later on? I always have 1 project to 1 solution so I want to use the convention of keeping my folder named the same as my project.
Question 2: What about the files that are still named with Project_A dot blah blah. Is it bad if I renamed these to Project_B dot blah blah?
A whole bunch of exciting new stuff announced around the Visual Studio Express Editions today. VS Express is now free for good, not just 1 year (just like SQL Server!). Also lots of great new content and fun projects to do.
See Dan Fernandez's blog posting at http://blogs.msdn.com/danielfe/archive/2006/04/19/579109.aspx for lots of details.
I'm trying to do some basic stuff in SQL Server 2005 that I could do in Oracle. I'm sure there's a way to do these things, I just don't know how. My most immediate question is this: Is there any easy way to run a SQL script and have it spool to HTML tables to a file? The 'results to text' from SSMS is not adequate for display purposes. I'm trying to display table/column descriptions. Beyond that, does anyone know of any good resources that provide an 'Oracle to SQL Server' matrix so I can help figure out how to do some of these things in SQL Server? Thanks in advance, Mike
BACKGROUND: I just set up a network with 2 computers (direct cable network, no routers/hubs), one computer is running Windows 2000 Server and the other is running Windows XP Professional. They both recognize each other and I can access each computer on either computer. The WinXP computer has SQL Server 2005 express edition installed on it.
BASIC PROBLEM: I am trying to install a database server on my Windows 2000 Server OS computer. This computer is a 350MHz, 256mb RAM computer. How would I go about doing this?
I have the following query that supposes to merge multiple result in a single one and put it into a temporary table:
SELECT DISTINCT [AlphaExtension], STUFF((SELECT A.[NoteText] + '< BR />' FROM #temp A WHERE A.[AlphaExtension]=B.[AlphaExtension] FOR XML PATH('')),1,1,'') As [NoteText] FROM #temp B GROUP BY [AlphaExtension], [NoteText]
It is working fine unless by a simple detail. If you look at the second line of the query you will see that I am stuffing together a < BR /> tag (break line) because the contents of the field is going to be spitted directly to the screen and I want that the multiple results be displayed in different lines.
OK, the issue is that it is stuffing & lt ; BR / & gt ; instead < BR /> and therefore the browser is displaying the tag instead to break a line.
I have a column which needs to be 9 digits long. The first four digits are independent from the other digits. The following digits need to be 5 and I have to add leading zeros if they're less than 5. This is an awful design and I'd love to change it but I can't.
