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 have one partition table "tablea" with partition key dateentry on yearly basis and table have four partition with name y2013,y2014,y2013,y2015 with one partition schema . How I can create partition index on tablea that first time create partition  index  and next time I want to rebuild index only on y2015 partition .Â
I have created a horizontal partition view from 4 physical tables. just wondering how the index works in the partition view: 1) If I need to build an index on a column, do I need to build it on all 4 physical tables? or I just build it on the view? or build it on view and 4 physical tables?
2) If I build it on view, and if I add a table into view, do I need to recreate all indices on the view?
Is there anyway to drop an index at the partition level in SQL 2005 ?There is a way to rebuild at the partition level (assuming this creates)i.e.: alter index ALL on dbo.LP_CQ rebuild partition = 229 ;I want to:1. Drop index(es) at partition level (partitioned by period value (1..400)).2. bulk copy data in (can be 1 or more periods per day).3. Rebuild at Partition level.Thx
I have a table partitioned by month. There are no primary key. There is another table with the same structure that I use to load data for the current month. I can perform partition switch with no problem.
I created non unique index on integer field in both tables. After this change partition switch does not work anymore. Here is an error that I am getting:
'ALTER TABLE SWITCH' statement failed. The table 'dbo.test' is partitioned while index 'IX_test' is not partitioned."
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?
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.

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? Thanks
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?
I have a table with 52 million rows which resides on Primary file group in my database. Because of huge number of rows the performance has gone very down and I would like to break the table into parts.
Can anyone suggest me the steps for doing the same and the number of parts that should be made. It is named as Account_Transactions and contains information of Policies in an insurance database.
How can I make partitions on a table for a particular value and ranges together?
For example, for customer id 12345 i need a separate partition, then for 56789 i need a separate partition, and if i have range of values like 1000 to 1020 then a separate partition for this.
For certain ids i need unique partition, and for certain ids i need Ranges.
I created two tables one is based on partition structure and one is non-partition structure.
File Groups= Jan,Feb.....Dec Partition Functions='20060101','20060201'......'20061201' I am using RIGHT Range in Partition function. Then I defined partition scheme on partition function.
I have more than 7,00,000 data in my database. I checked filegroups and count rows. It works fine.
But When I check the estimation plan time out for query it is same for both partition table and non partition table.

We have a table with 15 Partitions in SQL Server.Can i write a stored procedure or an SQL statement just to truncate a particular partition by passing the partition 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')
PLease help me to insert the non US records into the View
I am trying to partition the table i have into 10 partitions based on the last digit of the employee ID. The following is the logic I tried to use but was not successful.
Code Snippet CREATE PARTITION FUNCTION PartitionRange (INT) AS RANGE LEFT FOR VALUES (1,2,3,4,5,6,7,8)
CREATE PARTITION SCHEME PartitionScheme AS PARTITION PartitionRange ALL TO ([PRIMARY])
create TABLE PartitionedTable ( counter INT , string CHAR(8000) , EmpID INT, UpdateDate datetime ) ON PartitionScheme (EmpID % 10)
Any suggestions on how I can make the logic work as required.
I had a table which is going to burst, and of course performance issue is come in to place. and now we thinking to apply to partition method into this table.
So is that possible to create a partition scheme and against the existing table? and how is the T-SQL statement will be look like.
I'm running a merge replication on a sql2k machine to 6 sql2k subscribers. Since a few day's only one of the merge agents fail's with the following error:
The merge process could not retrieve generation information at the 'Subscriber'. The index entry for row ID was not found in index ID 3, of table 357576312, in database 'PBB006'.
All DBCC CHECKDB command's return 0 errors :confused: I'm not sure if the table that's referred to in the message is on the distribution side or the subscribers side? A select * from sysobjects where id=357576312 gives different results on both sides . .
Hi everyone, When we create a clustered index firstly, and then is it advantageous to create another index which is nonclustered ?? In my opinion, yes it is. Because, since we use clustered index first, our rows are sorted and so while using nonclustered index on this data file, finding adress of the record on this sorted data is really easier than finding adress of the record on unsorted data, is not it ??
I am new to Partitioning tables. My scenario is as listed below.
I am getting Monthly Transaction data on Every First Monday of the Month and I want to do partition for those data.
For Example: Let's say I will get my next monthly data on August 3rd 2015 which is First Monday of the month of August.
I want those Transaction data to go in new partitioned FileGroup in my existing partitioned table. How can I do partition for this kind of scenario ? Can we create one or multiple Stored Procedure which will create New Partition and load data in that partition ?Â
FYI, this monthly data will be loaded in Staging table and that table has LoadDate column which will have 2015-08-03 in it. I am using SQL 2012 Enterprise edition.
I am new to SQL Server. I have a table which is paritioned by Value (String). Can I write a stored procedure or an SQL Statment to truncate a particular partition in SQL Server. Please suggest me on this.
