Once I've added Files for a database across mulitple SAN drives will
SQL 2005 automatically partition data across the Files automatically?
Will it atleast grow across files automatically? Or do I have to do
Scheme Functions, Partitions, and assign the Scheme Partition to each
table in the database?
Thanks

I want to know how to partition a table using two columns (Example: Salesman, OrderDate).

View 1 Replies View RelatedAnanth writes "A new feature is established in SQL Server 2005. That is Partitioned Table. I went through several articles in net regarding partioned table. But I did not get any generalized version of Partitioning.
For example I partitioned a table into 4 Filegroups based on Transaction Date. So I used range function to give ranges for 4 quarters of one year. It works fine. But I would like to generalize this scenario. It will work for one year. If new year comes ,I have to write new script and execute the same.
The Partitioned function should work for 12 months in a given year. So here year is the paramter and then that function should be construct based on the year automatically.
Can anybody give me answer asap."
We currently want to move towards partitioning tables on a master server which is running SQL 2005 Enterprise Edition. However, we have transactional replication as well as log-shipping set-up against that server. The log-ship destination is also running Enterprise Edition, but the subscription server(s) are all Standard Edition only. Will there be any problems or special steps required in creating data partitions on some of these replicated tables if we don't upgrade our license?

Hi!
How to install sql server 2005 automatically with sa password
I want to know that i am creating a setup in visual studio 2005, i have set up sql server as prerequsite, by default the sql server installation is silent, it does not ask anything, in MSDE we had the facility of setyp.ini file which automatically creates the database with the settings provided in the ini file. Is there any option like this in sql server 2005 express editon.
[Options]
INSTANCENAME="MSDE"
SECURITYMODE=SQL

now what can be done in sql server 2005 express edtion
Iam aware that Microsoft SQL 2005 Express Edition does not have agent or DTS capabilities, but how may I automate an import of flat files to the DB tables? Must I use an external VB development of is there a way to schedule an import of flat files to Microsoft SQL 2005 Express Edition ?
View 11 Replies View RelatedI have a Visual Studio 2005 solution which contains a Sql Server Integration Services (SSIS) project.
In this solution I have explicitly set a Web application project as startup project, but whenever I edit a DTS package within the SSIS project, VS automatically sets the SSIS project as startup project and the package I edit as startup object.
Needless to say, this may cause some really unwanted incidents when running the solution - thinking that you're about to run the Web application project (that was explicitly set as startup project), but instead, you run the edited package in the SSIS project.
Is there any way to avoid having the SSIS project automatically setting itself as startup project, any workaround here at all? :)
Thanks.
I'm trying to automate an auto-export of a table on a daily basis,using BCP. I'm using native format for the BCP because the text inone of the fields can encompass pretty much any ASCII characters, andusing the other options (including the null terminator, stuff like|||, etc) hasn't worked particularly well.So, I'm archiving out a table on a daily basis. I want to script outthe table at the same time; that way, if there are any table changes,an import will still work.How can I do this? I've been digging through google for scripts withno luck. Ideally I'd like a table-creation script, along with CREATEINDEX statements.Anybody have a script handy for this? I know it can be done by usingthe system tables, but I'm hoping to avoid reinventing the wheel.Thanks in advance.Michael

I have begun my quest to become familiar with SQL 2000 table partitioning and have had some success.
I've partitioned tables according to the "rules" and guidlines of other papers and the show plans look good for all cases.
But when I went to create another demo series, I got stuck.
I've created two tables, with the appropriate CHECK constraints, and with a "union all" view.
When inserting data, it goes to the right tables.
When reading data with a where clause like:
col1=10,
the show plan shows the query getting the data from the ONE correct table.
BUT
When the where clause looks like:
where col1 between 1 and 10:
the showplan shows the query getting data from both tables, instead of the table that 1 to 10 belongs to.
Help!
Hi guys,
1) I'm about to implement SQL Table/Index Partitioning for the first time. It seems really good, no downside. Is there an "Gotcha's" I gotta be weary of?
2) My tests show a clear performance gain. Is there a performance loss in other areas?
In "Designing Partitions to Improve Query Performance" it says this:
"In this way, the SQL Server query optimizer can process the join faster, because the partitions themselves can be joined. If a query joins two tables that are not collocated or are not partitioned on the join field, the presence of partitions may actually slow down query processing instead of accelerate it."
What does that mean?
If I have:
Select A.Col1, B.Col3
from A
join B on A.Col5=B.Col6
Does that mean I have to partition A.Col5 & B.Col6 the same way else my queries will get slower?
3) Does it take up more space? Do restores take longer?
4) How much maintenance is involved?
Is there a way of automating the creation of new partitions? Or do you just create loads that you'll need in the future e.g. always have a few months' partition created ahead of time?
The "Designing Partitions to Manage Subsets of Data" article in BOL seems to indicate some manual work every month (if you have a monthly partitioning strategy).
5) Why not partition every table that has over say a million rows?
6) If I create a Yearly Partition on a table that has been around for a long time, will it automatically partition all the indexes on that table? Or do you have to re-create the indexes for that to happen?
7) Neither table can have a full-text index in a partition move. Does that mean you can't ever partition tables with full-text indexes?
8) Partitioning doesn't seem to fit well with replication. Do you have to end up choosing between the two?
i have a table named "user" in which user which are located at different places within a city are recorded.

Hi,
I want to know more on table partitioning.I do not know where to get the right info.from.
I have a doubt - if a table is partitioned horizontally how does a query identifies where to pick up the data from i.e. from which part of partitioned table?
I'm faced with a project that requires the caching of vacations.
Each vacation has a departure date & a price.
The amount of different vacations that will need to be cached is probably near 1 million per day.
I will then need to select the price(s) of vacations for either a single day or a date range (based on the vacation criteria).
I was considering creating a new partition (table with a date on it) every day.
This would allow me to jump into the needed table(s) based on the vacation search criteria. This would also allow me to drop tables with past dates.
I was considering running this all on 1 sql server. I was hoping I could create multiple threads for a datespan search and hit all the tables in the daterange at the same time.
Can you guys enlighten the noob on where I really need some help on this?
Hi,
I am trying to implement partitioning on a table
depending upon the fiscal_month value...
The current values are from 1-6...
Create partition function LoadDataPartitionFunction ( smallint)
as
Range for values (1,2,3,4,5,6)
-- drop partition scheme LoadDataPartitionScheme
create partition scheme LoadDataPartitionScheme
as
Partition LoadDataPartitionFunction ALL to ([PRIMARY])
CREATE TABLE Load_Data_Partition (

[Fiscal_Month] [smallint] NOT NULL,
[Fiscal_Year] [smallint] NOT NULL,
....
[Service] [nvarchar](100) COLLATE
) ON LoadDataPartitionScheme (Fiscal_Month)
truncate table Load_Data_old --- same schema as load_data_partition
Alter table load_data_partition switch partition 1 to Load_Data_old
-- which month's data to be moved out
alter partition function LoadDataPartitionFunction () merge range (1)
Alter partition scheme LoadDataPartitionScheme next used [primary]
-- which months data to be moved in
alter partition function LoadDataPartitionFunction () split range(7)
Select * from sys.partition_range_values

65545 3 1 4
65545 4 1 5
65545 5 1 6
65545 6 1 7
Alter table [Load_Data_new] switch to [Load_Data_partition] partition 6
ALTER TABLE SWITCH statement failed. Check constraints of source table Load_Data_new' allow values that are not allowed by range defined by partition 6 on target table 'Load_Data_partition'.
Values in Load_Data_new for fiscal_month is 7
But when i try
Insert into [Load_Data_partition]
Select * from [Load_Data_new]
where fiscal_month = 7
it works fine...

hi all,
before i had a big database more than 90GB and it's growing very sharp so what i did is to create a summary database that gonna hold some aggregation and i create also three tables that gonna hold the data, on will hold the data for the last three months (very detailed information) one between 3 months and a year(less detailed) and the last one older than a year(less less detailed) these are the company requirement i'm working with.
then i transfer the data to the new tables with stored procedures.
now my question is: do i need to create a view for these three tables? and if yes how should i do it?!! cus i do not have the same columns in the three tables.
thanks experts.
i want to partition a table containing about 3 million rows. The partition column will be of datetime type.
following is the partition function i have used
create partition function MyPartFun
(datetime) as range left for values ('07/30/2007','09/30/2007','11/30/2007','01/30/2008','04/30/2008')
following is the partition scheme i have used
create partition scheme PartScheme as
partition MyPartFun all to ([primary])
i know how to add partition column while creating the table
But dont know how to add above partition scheme to an already populated table
Plz help...

How to partition tables in dynamic way?
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)
Any help will be appreciated.
Thanks

two questions:
Im using Snapshot replication;
1. how can I replicate database1.table1 to database2.tablex1
by default replication will replicate it to database2.table1
2. If i have database2.table1 sitting on 10 partitions
where table is partitioned on PK_x where x is divided by 10
how can i make tableX1 to be a member of database2.table1
sitting on the 7th partition. that is pk_x = 70-79
partition schemes and function are already set
thanks
Hi Experts,
I am new to Table Partitioning, Can any body guide me how to do table partitioning?
any way here is my scenario, we are having one database called "DATA" in SQL 2000 server and we have migrated to SQL 2005 by using backup and restore. and "DATA" is having about 15 tables and they are very very very big in size. and they dont have any index on a coulum name "DATETIME", but i want make table partition according to that perticular field "DATETIME" and right present we are having 6 months of data.
So, how to proceed further?
Your help will be appreciable..
i am trying to partition an sql table in sql server 2005, i created the partition schema and the data files that i want the data to be filled in after the partition. After the partition is finished sql gave me partition is successful , but i noticed that the size of data files i created has not increased and their sizes are the same.
notice: i have a clustered index on this table, so i dropped this index and recreated it
Bellow the script that i am using
and thank you for your help in advance

I have a table that looks like this:

12345 3453 1
12345 546546 2

) ON [PRIMARY]
So this table has now reached over 22 million rows. The problem is my machine only has 1GB ram....so SQl Server tries to load up the whole table and this is ~560MB....equals zero ram for ...well anything else!
Does SQL Server load up an entire table when performing an INSERT?
Code Snippet
INSERT INTO ItemTokensLink(ItemID, TokenID, WordCount)
SELECT DISTINCT @ItemID as ItemID, t.TokenID, Count(t.TokenID) as WordCount
FROM #Tokens t
Group by TokenID
@ItemID is parameter provided
#Tokens is a temp table create with a word list
Would partitioning help here?
The table is is 80% of the time added to and the ItemID will always increase. What is the best to deal with massive tables that are inserted to frequently?
How does SQL Server decide when to load a table into memory?
TIA
Hello,
I have current events going to a log, and I'm implementing partitioning it into weeks using the following function...
CREATE PARTITION FUNCTION [trackPointLogWeekPF](int)
AS RANGE LEFT FOR VALUES (7, 14, 21, 28)
and in the table create I add an extra field of day number to pass to the function...
[intPartitionDayNum] AS (datepart(day,[dtTrackPointTime]))
So if that's all for the current month, is it possible to have monthly partitions for the older data so that I could drop off a month from a year ago for example or would I need to keep it weekly?
Thanks for any help.
I have a question about Partitions and if this is the best approach for my situation.
I have a table with many rows (300 Million or more) where there is a column that represents a date (actually it is an integer in the form of YYYYMM - example 200501 - January of 2005)
The data prior to a specific date (in my case 3 full years before the current YYYYMM - at this time 200501) is data that never changes. The data at that date (200501) and on is data that changes every month.
I have approximately 200 Million rows that are static (and growing every year) and 100 million that changes every month.
I wanted to do the following (and keep in mind i have to do a delete from this table every month and an insert every month)
1. Create a simple partition function like this to represent 2 buckets for data (one prior to 200501 and one post 200501)
CREATE PARTITION FUNCTION partPeriodData (INT)
AS RANGE RIGHT FOR VALUES (200501)
2. Create a partition scheme as follows (to separate the data from the two buckets onto two separate file groups)
CREATE PARTITION SCHEME partPeriodScheme AS
PARTITION partPeriodData TO
(ETOFinalHistoricalFG, ETOFinaCurrentlFG);
3. I Created my database as follows
CREATE DATABASE [Final] ON PRIMARY
( NAME = N'ETOFinalPrimary', FILENAME = N'd:DataETOFinalPrimary.mdf' , SIZE = 102400KB , MAXSIZE = UNLIMITED, FILEGROWTH = 102400KB ),
FILEGROUP [ETOFinaCurrentlFG]
( NAME = N'ETOFinalCurrent', FILENAME = N'd:DataETOFinalCurrent.ndf' , SIZE = 102400KB , MAXSIZE = UNLIMITED, FILEGROWTH = 102400KB ),
FILEGROUP [ETOFinalHistoricalFG]
( NAME = N'ETOFinalHistorical', FILENAME = N'd:DataETOFinalHistorical.ndf' , SIZE = 102400KB , MAXSIZE = UNLIMITED, FILEGROWTH = 102400KB )
LOG ON
( NAME = N'ETOFinalLog', FILENAME = N'd:dataETOFinalLog.ldf' , SIZE = 102400KB , MAXSIZE = 2048GB , FILEGROWTH = 102400KB )
GO
4. I Created my table as follows
CREATE TABLE [dbo].[f_eurostatdata](
[LoadId] [int] IDENTITY(1,1) NOT NULL,
[DeclarantId] [int] NULL,
[Partner] [int] NULL,
[ProductId] [int] NULL,
[Flow] [int] NULL,
[Stat_Regime] [int] NULL,
[Period] [int] NULL,
[Value1000ECU] [numeric](34, 4) NULL,
[QuantityTon] [bigint] NULL,
[SupQty] [numeric](34, 4) NULL,
[DateCreated] [datetime] NULL CONSTRAINT [DF_f_eurostatdata_DateCreated] DEFAULT (getdate()),
CONSTRAINT [PK_f_eurostatdata] PRIMARY KEY CLUSTERED
(
[LoadId] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON partPeriodScheme(Period)
When i create my table i get the following message
The filegroup 'PRIMARY' specified for the clustered index 'PK_f_eurostatdata' was used for table 'dbo.f_eurostatdata' even though partition scheme 'partPeriodScheme' is specified for it.
Am i doing this right?

Hi,
Pls advice on how to partition an existing non partitioned table having a fair amount of data.

RT
We have purchased a new Server at my company. We previously had two servers. One was the NT file server and then we had another SQL Server. Well, we've bought one box to replace both old boxes. I have 3 18.2 GB SCSI drives running on a RAID-5 configuration. I've partitioned the C: drive as 2GB and it will only be used for NT files and NT Utility apps.
On the old system I had all my data files on one physical drive and all of my logs on a seperate physical drive. Now, with RAID, the three drives act like one big 36GB drive. Finally, my question...
How should I partition this drive? Should I put the SQL Server App, my data files and my logs all on one partition? Should they each have their own partition? Should it be a mix (App & Log, Data & Log, etc.). Also, how much space do I need just for the application if I put it in its own partition?
I've never installed SQL Server before, so if anyone has any other suggestions, tips, tricks, etc., I'd love to hear it. Either post here or e-mail me responses.
Thank you all very much
Merry Christmas!
Hi,
Just got a new box and want to fully optimize the server. I was contemplating where to put the transaction log? I have 2 drives:
Drive C: 30 Gig(Operating System)
Drive E: 180 Gig(Database file)
I'm planning to build the database in Drive E:, but am leaning to put the transaction log in drive C:. Do you think it's a good move? I want to separate the log and data files, but Drive C: is host the operating system. Do you think it would be wise to partition drive C: and put the operating system on one partition and the Transaction log on the other? Does it enhance performance in anyway?
Thank You!
Joe
