hello
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 ?
I have a problem while I try to insert data into a partioned view I am
getting the following error.
Server: Msg 4436, Level 16, State 12, Line 9
UNION ALL view 'sales_all' is not updatable because a partitioning column
was not found.
Any thoughts

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
I'm running sqlserver 2000 enterprise edition on windows 2000 and I need
to know, how to create partition table. Please give me a small partition table example.
Thanks,

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',
'01/01/2004','01/01/2005','01/01/2006','01/01/2007')
--------------
create partition Scheme ps_RecBuyLoadDateScheme
as partition pf_LoadDate
to (FG1,FG1,FG1,FG1,FG2,FG2,FG2,FG3,FG3,FG3)
I'll appreciate any help.

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?

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

I have a partitioned view sitting over several tables and I'm slowlyapproaching the 256 number. Can anybody confirm if there is such alimit for the maximum number of tables that a partitioned view canhold?If this is true, does anybody have any suggestions or ideas to workaround this max limit?TIA!
View 4 Replies View RelatedHi Friends,I have 3 labels Steet,City,Pincode and 3 textboxes related to the labels and one button as nae 'Address'I gave the data for Street:abc,City:xyz,Pincode:123 and have to insert into the table.I created one table in the database with table name Adreess and column address varchar(100)but after giving the values in the textboxes and clicked on the button its throwing the exception i.e System.Data.SqlClient.SqlException: The name "abcxyz123" is not permitted in
this context. Valid expressions are constants, constant expressions, and (in
some contexts) variables. Column names are not permitted.I wrote the code like following protected void Button1_Click(object sender, EventArgs e) { string street = txtStreetNo.Text; string city = txtCity.Text; string pincode = txtPincode.Text; string com = street + city+pincode; conn.Open(); SqlDataAdapter daInsert = new SqlDataAdapter("insert into Address values(" + com.ToString() + ")", conn); daInsert.SelectCommand.ExecuteNonQuery();--->here its giving the exception conn.Close(); Response.Write("the values are inserted"); }Please any one tell me am I did the code write or not if its not please give any suggetionsthanksGeeta

Declare @XMLCurrency nvarchar(max)
Set @XMLCurrency='<R><T><A>0</A><B>USD</B><C>840</C><D>US Dollar</D></T></R>'
Value 840 should insert into column ISONumbricCOde .
value USD should be insert into ISOCode column.

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 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?

Hi,I have a table with 20.000.000 of tuples.I have been monitoring the performance of the insertion and updates,but not convince me at all.The table have 30 columns, what and 12 of it, are calcultated column.The test that i do was this:1 Insertion with all the columns and calculing the calcultated columnsin the insertion sentence.1 insertion and all the columns calculated in @vars..1 insertion with the basic fields, and 10 updates.And the result was that the last test was the most performant.What is your opinion?
View 4 Replies View RelatedHi Experts,
I need to know the best approach to save data in master table and then in detail table.
I know this method but i know it's not a good approach why i will explain
Insertion in Master Table..................................... A
Insertion in Detail Table........................................B
Now if there is any exception occurred while step A then the step B will not take place which is ok but if there is exception while step B then the process A will have completed
i.e the data in master table will be Inserted/Deleted/Updated but there will not be a corresponding action in Detail table which is not good approach.
So please can any one tell me a good approach for this.
Hi there
I have a relatively noobish query and I am hoping to get a solution to it.
Heres the query in a nutshell.
I have a 'Type' table which has a 'TypeName' varchar attribute. So when I do a row insert into this Type table, I want a new table created with the value I insert into the 'TypeName' column as the table name.
For example If i insert 'xyz' into the 'Type' table for the 'TypeName' column. I wish for a trigger to fire which will create a table 'xyz' with some set attributes. I am really new to SQL Server and my preliminary googling left me disheartened with the results. So here I am.
I hope I was clear in the way I expressed my doubt and also that the people here might be able to help me out in this quest.

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

how to restrict data insertion upto 50 MB in a table?
View 1 Replies View RelatedHi,
This problem is connected with the query i posted yesterday regarding insertion of global variables. I was able to insert the variable in a table to check its value.
This value is mapped to the global variable in a previous Execute SQL Task. But when I use the same global variable to insert in a table, default value 0 is inserted.
My query is does the global variable declared at the package level does not store the value mapped across multiple tasks in control flow?
How can i insert the value stored in a variable in a table from previous SQL Task.
Can anyone suggest some solution,links to try a workaround?
Thanks in advance.

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 a few databases that are using Partitioned Views in order to manage the table sizes and they all work well for our purposes. Recently I noticed a table that had grown to 400+ million rows and want to partition it as well, so I went about creating new base tables based on the initial table's structure, just adding a column to both table and primary key to be able to build a Partitioned View on them.The first time around, on a test system, everything worked flawlessly but when I put the same structure in place on the production system I get the dreaded "UNION ALL view 'DBName.dbo.RptReportData' is not updatable because the primary key of table '[DBName].[dbo].[RptReportData_201405]' is not included in the union result. [SQLSTATE 42000] (Error 4444)" error.
I have searched high and low and everything I see points to a few directives in order for a UNION ALL view to be updatable:
- Need a partitioning column that is part of the primary key
- Need a CHECK constraint that make the base tables exclusive, i.e. data cannot belong to more than one table
- Cannot have IDENTITY or calculated columns in the base tables
- The INSERT statement needs to specify all columns with actual values, i.e. not DEFAULT
Well, according to me, my structure fulfills these conditions but the INSERT fails anyway. CREATE scripts below scripted from SQL Server. I only modified them to be on a single row - it is easier to verify that they are identical in a text editor that way.

HI,
How to create package in SSIS by applying the business Logic like if the record already exist it should be and update else it should be an insert in the destination table. how to achive this funcality in SQL SERVER 2005 (Business Intelligence studion).

Consider a 4 tables where 1 of them is considered to be as the parent class and the other 3 are sub-classes and they are disjoint so for every recored i insert in the parent class i want to also insert in one of the subclass according to a condition which checks a certain attribute in the recored that is also entered in the parent class .. how could this be done .
View 8 Replies View RelatedI 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.
Hi,
I found out that executing the procedure SP_INDEXOPTION and setting 'AllowRowLocks' to false i can prevent the sql server from locking rows in a table and 'AllowPageLocks' prevents from pages being locked. I need to preform same operation
in case of tables. I need to perform insertion operations concurrently and acquire required locks manually. Is there a way to stop sqlserver from acquiring locks on the table. I need to disable all the locks (row, page and table).
Thank you in advance.
Hi,
I've starting to explore the Distributed Partitoned Views, in order to use it in the next project, and I've found the article:
"MS SQL Server Distributed Partitioned Views"
By Don Schlichting
I came across the following problem:
While running sample:
USE test
GO
CREATE VIEW AllAuthors
AS
SELECT *
FROM AuthorsAM,
TEST1.test.dbo.AuthorsNZ
GO
I got the error message:
Server: Msg 4506, Level 16, State 1, Procedure AllAuthors, Line 5
Column names in each view or function must be unique. Column name 'au_lname' in view or function 'AllAuthors' is specified more than once.
Could anyone please explain? Can't i use the same column names in both tables?
