Thanks Pinal. Keep it up.

Select $partition.TESTDB_PARTITIONRANGE(id) AS [Partition Number],* from testtable
where $partition.TESTDB_PARTITIONRANGE(id)=1

if some one is having any other or better way, please share.

Thanks

How to view the data of any specific partition ?

Thanks
Manish

Think of it like this.. India is made up of 28 states… Relate each of the state as partition… Now if I need information of a person residing in Gujarat , the query will hit only the people information staying in gujarat as opposed to all 28 states and thereby improving performance of the query

Since the query wont have the account information , it will have to check all partitions to get the data assuming the partitions are created on Account

partition column and UNIQUE clustered index key column is different. that time i created partioned for table. but table–>properties–>storage doesn’t show partition. but if i use select * from sys.partitions where object_name(object_id)=’tablename’. it shows partioning except clustered index..what is the difference?..is this correct way to partition?

advance THANKS for you help

How select command will work after partitioning ,while retrieve the data from the table?

But when attaching it has thrown an error saying that due to a partitioning this cannt be attached.

Pls. advise me to remove the partition and attach it to SQL Server in my PC….

Thanks for such a nice article, I have a question regarding the partition, that is I thought it will divide the rows between two parts through out the insertion process but it has inserted only 10 rows in first part and all other in to part2, is there a way I can equally distribute the rows among two partitions.

Thanks & Regards

Partition function can only be created in Enterprise edition of SQL Server. Only Enterprise edition of SQL Server supports partitioning.

How can I solve with this situation? please explain to me

I am very appreciated !

Kevin

I have partitioned my table by a DateTime field “RecordTime” and have partitioned it by MONTH

Two questions:

1. Is there a query to retrieve the field name on which a table was partitioned ?

2. Is there a query to retrieve the partition ranges? In my example I am expecting to see the list of current partition ranges like Jan2011, Feb2011

Thanks.

Will

I have a requirement to set-up an MS SQL Server 2005 (or 2008) database to hold significant amounts of transaction data. One table needs to hold 26 Gigabytes of data and the other, 3 Gigabytes. This is for data querying of the transaction data.

First question is ‘Can it be done?’ in MS SQL Server.

Would I need to partition the tables over a number of hard drives to make this work?

What typical hardware configuration/approach would be recommended if the answer is YES?

Thanks in advance folks for any help, much appreciated…

Regards

Mark.

ALTER TABLE SWITCH statement failed. The specified partition 13 of target table ‘jfcdw_prd.dbo.FactSales_CK’ must be empty

how should I, select only one year1
