Hi All,
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.
Thanks

Hi all,
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.
Any Suggestions??????????
Thanks
Chow.
I want to find a way to get partition info for all the tables in all the databases for a server. Showing database name, table name, schema name, partition by (maybe; year, month, day, number, alpha), column used in partition, current active partition, last partition (for date partitions I want to know if the partition goes untill 2007, so I can add 2008)
all I've come up with so far is:
Code Block
SELECT distinct o.name From sys.partitions p
inner join sys.objects o on (o.object_id = p.object_id)
where o.type_desc = 'USER_TABLE'
and p.partition_number > 1
hi list
i have a table named stgBudgetFact, that is partitioned on DivisionID.
each DivisionID goes into its own partition, which is on its own file group.
the etl guru on the project wants to be able to truncate the partition, not do a delete from the table based on DivisionID.
Is it possible to truncate the partition somehow (remove rows where DivisionID = 3 for instance without ALTER DATABASE, where the medicine is worse than the disease) and then reestablish the partition so we can restart a failed load by division?
i really hope something like this is possible
thanks

I'm having a problem creating a partitioned table with a filestream column. I'm getting error: Cannot create table 'MyTable' since a partition scheme is not specified for FILESTREAM data
CREATE TABLE MyTable
(
IndexID BIGINT IDENTITY(1,1),
PartitionID SMALLINT,
IndexGUID UNIQUEIDENTIFIER NOT NULL ROWGUIDCOL
[code]...
I actually managed to get the table created. The table below gets created. I had to specifically indicate that the unique constraint is on [PRIMARY] (non-partitioned) and create a partition scheme in the filestram filegroup. However my problem now is with partition switching. I successfully created a non-partitioned staging table identical to the partitioned table, but the switching operation doesn't work.
CREATE TABLE MyTable
(
IndexID BIGINT IDENTITY(1,1),
PartitionID SMALLINT,
IndexGUID UNIQUEIDENTIFIER NOT NULL ROWGUIDCOL
CONSTRAINT DF_MyTable_IndexGUID DEFAULT (NEWID())
[code]...
I get error:
'ALTER TABLE SWITCH' statement failed. The table 'MyTable' is partitioned while index 'UQNP_MyTable_IndexGUID' is not partitioned.
However, I can't drop the non-partitioned unique index on MyTable as it violates the filestream, and would make the table unusable.
I have some Partitioned Views and on all queries using a table for the in clause, table elimination isn't happening.
Check Constraint is on the oid column
This works as expected, only goes to 2 tables;
SELECT *
FROM view_oap_all
WHERE oid IN ( '05231416529481', '06201479586431' )
This works as expected, only goes to 2 tables;
SELECT *
FROM view_oap_all
WHERE oid IN ( SELECT oid
FROM owners
WHERE oid IN ( '05231416529481', '06201479586431' ) )
This is checking all tables (headingnames are unique), ive tried this for the last 3 hours on many different tables containing the oid column.
Unless I write the oid as in the above queries it just doesn't work.
SELECT *
FROM view_oap_all
WHERE oid IN ( SELECT oid
FROM owners
WHERE headingname = 'TestSystem' )
I have a query that has a left join with a large partitioned table. The partitioned table has 10s of millions of records, and each partition has about 100,000 records.
The left join is part of an insert that gets a column from the partitioned table, if the column exists. The query contains the partition ID and all other joined columns are part of a non-clustered index.
Through the profiler, I found that there were millions of reads and the execution plan was giving me a table scan on the partitioned table.
I changed the query to do the insert followed by an update with inner join. That did the trick, but it worries me that SQL Server 2014 behaves differently from 2012 or 2008R2, which can make upgrading very time consuming.
I have few tables, which are replicated and partitioned. They also have archival process. I want to avoid having to run that same process on the subscriber.
Replication of partition switching is easy. However I am not sure how to replicate merge range and empty filegroup/file drops.
There the following article options:
Copy file group associations
Copy table partitioning schemes
Copy index partitioning schemes
I am not sure if these are enough to implement the replication of merge range and empty filegroup/file drops.
I could not find and option to copy partition functions.
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')
PLease help me to insert the non US records into the View
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]
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.

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.
View 4 Replies View RelatedI have a basic load proc (loading a staging area.) that truncates a target table just before inserting fresh data in said table, all wrapped in a distributed transaction. What happens (only with certain tables and very inconsistently.) is the truncate will fail (no error) and duplicate data ends up in the target table since no wipe actually occurs. This proc only started having this issue when we went from SQL 2008 to SQL 2014.

We used to used Sql Server 2000 DTS to perform daily backups to remote servers very successfully but just cannot do the same with SSIS.
I set my Transfer Sql Transfer Objects Task to use the following settings:
CopyData = true
ObjectsTocopy = All Tables
As soon as it hits a table that has a foreign key, I get the following error:
"Truncate data failed for Table nnn"
I've tried setting DropObjectsFirst = True but this fails too with foreign key violations.
First of all, am I doing something obviously wrong? Is SSIS not smart enough to drop tables in the right order so that we don't get foreign key violations?
Am I totally barking up the wrong tree with this and can anyone suggest a better way of doing remote backups?
Kind regards

i want to ask if the insertion of a record into a partion is slower than insertion it into a non partitioned table or not?
cuz sql has to decide to wich partion the record has to insert according to the partitioning key and is this decesion process is making insertion slower ?
Hello;
I have inserted 200m rows into a partitioned table using SSIS, the table has a [RecID] column which is an identity(1,1) primary key.
When I open the table, I see that RecId doesn't start from 1(its not ordered), it starts from 889823. But, when I query the table for RecID = 1, I can see that row.
Is it a typical behavior of a partitioned table? Or am I doing something wrong?
This is the query I used to create the partitioned table.
create partition function pf_LoadDate(Datetime)
as range right for
values ('01/01/1997','01/01/1999','01/01/2001','01/01/2002','01/01/2003',

Hi,
Has anyone had any problems on one row updates on a table where you have defined horizontal and vertical partitioning of the data to be replicated?
When I execute an update clause that modifies just one row the log reader misses the modification and it does not get replicated to the other databases.
If I do the same update clause but on several rows then all the modifications are read by the log reader and the replication task goes ok.
What might be wrong?

I couldn't find any tutorials/articles on integrating a SharePoint web service call with an SSIS package
I need to schedule a web service to truncate and populate SharePoint Lists (2007 & 2003) from a SQL Server 2005 table.
I guess I'm just ignorant about integrating web services with SSIS. How do I make a call to the web service through my SSIS package? (script task?)
Any links to articles/tutorials or pointers would be apreciated.
I began with a partition function as follows:
CREATE PARTITION FUNCTION [TimeTicksRangePFN](bigint) AS RANGE RIGHT FOR VALUES (633294720000000000, 633320640000000000, 633347424000000000, 633374208000000000, 633399264000000000)
These numbers happen to correspond to the dates 11/1/7, 12/1/7, 1/1/8, 2/1/8 and 3/1/8 in ticks respectively.
I began with a partition scheme as follows:
CREATE PARTITION SCHEME [TimeTicksRangePScheme] AS PARTITION [TimeTicksRangePFN] TO ([FG_xxx_EventArchive00001], [FG_xxx_EventArchive00002], [FG_xxx_EventArchive00003], [FG_xxx_EventArchive00004], [FG_xxx_EventArchive00005], [PRIMARY])
While running my “sliding window script� , which I hoped would 1) roll off the oldest partition of my EventArchive table and 2) add a new partition with a tick boundary that equates to 3/5/8, I get an error related to my switch out table's index, the same table's Filegroup and Primary.
After getting the error, I scripted the partition function as a create in mgt studio and got…
CREATE PARTITION FUNCTION [TimeTicksRangePFN](bigint) AS RANGE RIGHT FOR VALUES (633320640000000000, 633347424000000000, 633374208000000000, 633399264000000000, 633402720000000000)
...which looks like what I had intended cuz the last boundary is the tick representation of 3/5/8 and the oldest has rolled off
scripting the scheme produced...
CREATE PARTITION SCHEME [TimeTicksRangePScheme] AS PARTITION [TimeTicksRangePFN] TO ([FG_xxx_EventArchive00001], [FG_xxx_EventArchive00003], [FG_xxx_EventArchive00004], [FG_xxx_EventArchive00005], [PRIMARY], [FG_xxx_EventArchive00001])
which looks nothing like what I intended, I thought I’d end up with …00002,…00003,…00004,…00005,…00001,PRIMARY
the script steps that seem most relevant start at the 5th step as follows...
5) creates table [dbo].Switch on the switch out filegroup with columns, PK and indexes matching exactly those of [dbo].EventArchive
6) switches partition 1 of [dbo].EventArchive to [dbo].Switch
7) ALTER PARTITION FUNCTION TimeTicksRangePFN() MERGE RANGE (633294720000000000) --this was the oldest date corresponding to 11/1/7
8) truncates [dbo].Switch
9) drops all indexes on [dbo].Switch except a clustered index (IX_TimeTicks), leaves PK constraint alone
10) ships the new data whose values range from 3/1/8 to less than 3/5/8 to [dbo].Switch and deletes them from their source
11) recreates all non clustered indexes on [dbo].Switch
12)ALTER TABLE [dbo].[Switch] WITH CHECK ADD CONSTRAINT RangeCK CHECK ([TimeTicks] < the number of ticks represented by 3/5/8)
13)ALTER PARTITION SCHEME TimeTicksRangePScheme NEXT USED [FG_xxx_EventArchive00001] --fg isnt really hardcoded
14)ALTER PARTITION FUNCTION TimeTicksRangePFN() SPLIT RANGE (the number of ticks represented by 3/5/8)
15)ALTER TABLE [dbo].[Switch] SWITCH TO [dbo].[EventArchive] PARTITION 5
step 15 is the one that fails with message "ALTER TABLE SWITCH statement failed. index 'xxx.dbo.Switch.IX_TimeTicks' is in filegroup 'FG_xxx_EventArchive00001' and partition 5 of index 'xxx.dbo.EventArchive.IX_TimeTicks' is in filegroup 'PRIMARY'.
I have a very large table that I am trying to partition and use to reduce maintenance overhead as well as improve performance. The table contains about 12 years worth of data but only the most recent years is inserted/updated/deleted from thru the app. I created partitions on a computed(persisted) column which holds the "year" value derived from a date column. I have created the partitions with all the default set options, and the stored procedure which performs the delete against this table also was created with no special set options(basically database/session default). Yet, every time I try to run the proc to delete data thru the app, I get this error:
Msg 1934, Level 16, State 1, Procedure xxxx, Line 118
DELETE failed because the following SET options have incorrect settings: 'ANSI_WARNINGS'. Verify that SET options are correct for use with indexed views and/or indexes on computed columns and/or filtered indexes and/or query notifications and/or XML data type methods and/or spatial index operations.
I've tried setting ANSI_WARNINGS on and off when creating the proc, inside the proc etc.., its always the same error whatever I set the option to.
Is there a way to figure out if a table is partitioned by month/day in SQL.Â

Hello,
The illustration below is for a customer dedupification project.
The Source file, containing customer name and address records, is conditionally split based on 7 ranges of substring(city,1,2) to distribute the load across 7 different threads for parallelization. Each customer record in the source file
is looked up against a reference table named Location_Stage for its existence using the Fuzzy Lookup
transformation.
The reference table Location_Stage has around 10 miilion+ records. The source file would normally have around 1 million
records.
I am wondering :
- if it would be possible to partition the Match Index of the reference table (NOT the reference table) into
7 partitions based on 7 ranges of substring(city,1,2) and maintain these partitions on different drives?
- if it is possible to specify a particular partition to be used by a FzLkup transformation?
- if the partitioning approach will improve the performance of the Fuzzy Lookups?

I am using SQL Server 2000, SP3.I created an updatable partitioned view awhile ago and it has beenrunning smoothly for some time. The partition is on a DATETIME columnand it is partitioned by month. Each month a stored procedure isscheduled that creates the new month's table, and alters the view toinclude it. Again... working like a charm for quite some time.This past weekend I moved some of the first tables onto a new filegroup. I did this through Enterprise Manager, by going into designmode for the table, then going into the properties for the table andchanging the file group there as well as in all of the indexes. Nowthe partitioned view is no longer updatable. It gives the errormessage: "UNION ALL view '<view name>' is not updatable because apartitioning column was not found."I have extracted the DDL for all of the partition tables and comparedthem and they all look the same. I checked and then double-checked theCHECK constraints to make sure that they were all valid and they are.If I remove the tables that I moved to the new file group from theview, then it is once again updatable, but when I put them back in itfails again.Any ideas? If you would like samples of the code then I can send italong, but it's rather large, so I have not included it here.Thanks!Thomas R. Hummel
