I'm looking to partition a big table into years.
I have a big table with data going back to 2001.
I need to partition this into file groups each for the last 5 years, and the rest into its own file group
I was going to convert the inherent date time field into the format int(yyyymmdd) and partition on that field.
Is this an acceptable way to achieve this? Is there a better way to partition on date? [not time]
I have the following table struction, lets call it table A.
bookidstartdate endate
2001 2000-01-01 2000-01-05
3001 2001-01-01 2001-01-02
4001 2002-01-01 2002-01-04
and i want the end result to be look like this in table B.
bookidstartdate endate bookidrowdate bookidlogseqrowsequence
2001 2000-01-012000-01-05 2000_01_01 2001_0 0

The script below works but i have a break when datediff (days,startdate, endate) reaches 0. For every bookidm i want to iterate till the datediff is zero then move on to next bookid and do the same thing.

I work for a 24/7 shop. We currently have a table that is partition on monthly. I have to created a script that will add a new file group, add the new file to the group, and alter the the partition scheme and function. However, I need for this process to not cause a lock on the table. Typically I get the locking and issues when I am run the split command. Is there a way to prevent this from happening?

I have tables:

I have created the T1 table which will accept US records and T2 table for any other country.
CREATE TABLE T1(I INT unique ,name varchar(10) CHECK(name = 'US') PRIMARY KEY(I,name))
CREATE TABLE T2(I INT unique ,name varchar(10) ,CHECK(name NOT IN ('US')) PRIMARY KEY(I,name))
Then Created the partitioned View using below script
CREATE VIEW V AS
SELECT * FROM T1
UNION ALL
SELECT * FROM T2
I am able to insert the US records using view
insert into V values (1,'us')
Problem:
I am not able to insert the non US records like UK and JN...
It is thorwing the exception like partition column not find.
eg : insert into V values (1,'uk')

Can we create the Partition on Existing Table?e.g Create table t ( col1 number(10,0), Col2 Varchar(10)) ;After the table Creation can we alter the table to partition the table.
View 2 Replies View Relatedwe planning to create partitioning on existing tables. The partitioning is on date column, there should be one partition for each year.
Creating of new partitions should be automated, and also we dont have any plans of archiving old data, all we want is that new partition creation should be automated.
When you load the data into a new partition table, can it to done online without any downtime? because I have few tables that are around 250 gigs and more.

Partition an existing SQL Server Table

I want to create multiple partition schema on a single table.
For example - i need to create partition base on region id and Territory Id.
A common partitioning scenario is when the partition column has the same value for every record in the partition, as opposed to a range of values. Am I the only person who wonders why there isn't an option to automatically partition a table based on the unique values of the partition column? Instead of defining a partition function with constants, you ought to be able to just give it the column and be done. This would be particularly valuable for tables partitioned on a weekly or monthly date; when new data is added it could simply create a new partition if one doesn't already exist.

I use sql 2005. What is the best practice for dealing with large table (more than million rows)? Table Partition, View or other?

Thank you!
A customer wants to implement table partitioning on a replicated table.
They want to hold 13 months of data in the table and roll off the earliest/oldest month to an identical archive table. The table has a date field and partitioning by month makes sense all around.
So SWITCH PARTITION is the obvious solution to this, except for the fact that the table is replicated (transactional w/no subscriber updates).
What are his architectural or practical solutions to using table partitioning and replication?
thx
Hi
Please help me how to do the Horizontal table partition??
I have to split the table in to multiple sub tables with same columns and less rows and then I have to use each sub table.
Thanks you in advance....

All,
I have a partitioned table (1.7 billion rows) that is across 97 partions. The table is partitioned on datetime field.
When I query only this table with datetime field in where clause I see that cleary it outperforms the unpartitioned table.
When this table is joined to 3 tables it performs no better than
the non-partitioned table... it seems that the query does a partition scan.
The part. table has a 3 part composite clustered index and
a NC index on the partion field value.
Would appreciate any feedback.
thanks

How do you alter the table to use the new partition (I know ALTER TABLE is in there but BOL doesn't give a valid example with the move option)? I can create the partition but I want to apply it to an existing table with no partition?

Hi all,
My question is about Indexs on partition where I have a table with say 5 partitions and I want to create index on partitions and not on the whole table. The objective is that if i create a table level index on a partition table and eventually if I drop one of the partition or add another partition, what will happen to the index?
1) Do I need to re-create the index for the partion which are left after deleting one partition?
2) If a partition is added do I need re-create the index for the whole table or just create the index for that particular new partition?
Let me know if there is any white paper or code available. I have gone through the white paper published "SQL Server 2005" Partitioned Tables and Indexes Author: Kimberly L. Tripp, Founder, SQLskills.com
I would like to partition a table having only items posted in the last 24 hours in one filegroup and all others in another. Is there a way that my partition function could contain something like "col1 >= dateadd(d,-1,getdate())" and have items move to the secondary filegroup as they age pst 24 hours?
Thanks

I am not worried about other attributes in the same table.
I have one environment where we get number of changes everyday. It takes time to take backup of database and then apply the script. I am thinking to automate it as
1. SQL Script (Hot-fix) will put in Shared folder accessible by SQL server.
2. I am writing a SP which will have parameters. Database name, SQL script, HF number.
SP will first take copy_only and compressed (all db's are 2008R2) backup of database. It will record SQL HF script from table into one row and it will apply that script to database using executesql. I am not able to take that SQL script in row.
