DB Design :: Alter Partition Function In Data Vault Where There Is 4 Table Dependency?
Aug 28, 2015
I'm currently stuck with a table that has 350 mil records. Querying this table is insanely slow so I had a better look at existing yearly partitioning. I already managed to partition on a month level which increased the performance/querrying a lot. I did this on the staging table where I used an alter statement to split the 2015 partition by 12 months.
However, in our project we used Data Vault. This means that we have 4 tables (hub, sathub, link, satlink), all carrying 350 mil records. The problem is that altering the partition function does not work. The server cannot handle this action. What the best way is to do this, without having to drop/reload all tables.

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

Normally we create a new table for tabler partitioning, like:
Code Snippet
CREATE TABLE [dbo].[Sales]
(
[SalesID] [int] IDENTITY(1,1) NOT NULL,
[SalesDate] [datetime] NOT NULL,
[col_01] varchar(50) NULL,
[col_02] varchar(50) NULL,
..
) ON [ps_Sales](SalesDate)
GO
with
Code SnippetCREATE PARTITION SCHEME [ps_Sales]
AS
PARTITION PFN_Sales TO ([FG_20080501], [FG_20080516], [FG_20080601], [FG_20080616],
[FG_20080701], [FG_20080716], [FG_20080801], [FG_20080816],
[FG_20080901], [FG_20080916], [FG_20081001], [FG_20081016])
But what if I have [dbo].[Sales] existed in db, that have attached to [PRIMARY]?
Alter table?
or I need to create a temp table first?

I create a partition function , on date filed and all Data records per month was appointed to a separate file.And is partitioning only for Future data entry?

I'm working on re-indexing a table using some commands from ALTER INDEX REBUILD from Microsoft. The indexes will be tested for threshold fragmentation. my plan is once the reindex is executed, a transaction backup will occur while controlling the size of the log file. Â The query impose time limitations or stop reindexing after the specified amount of time has elapsed.
my question,
1. How can I integrate a query which checks if transaction log is getting full and which runs a Tlog backup if over 70%
2. How do I impose time limitation?

Hi,
I have a big table which is partitioned , I need to change the portioning function (including the column used by partition key). I don€™t want to change the table or use a temp table as there are a lot of dependent objects to this table
I wrote:
DECLARE @partition_count INT,@cmd VARCHAR(8000)
SELECT @partition_count=MAX(p.partition_Number) FROM sys.allocation_units A,sys.partitions P ,sys.data_spaces D
WHERE P.OBJECT_ID=OBJECT_ID('TABLEA')
AND A.container_id=P.Partition_id
AND A.data_space_id=D.data_space_id
SELECT @partition_count
WHILE (@partition_count>1)
BEGIN
SELECT @cmd='ALTER PARTITION FUNCTION MainPartitionFunction() MERGE range ('+CONVERT(VARCHAR(10),@partition_count-1)+')'
exec (@cmd)
SELECT @partition_count=@partition_count-1
End
Which will merge all the existing partitions to one. But I don€™t seem to be able to find a way change the existing funtion. ( in need to change the partition key all together)
Is there a way to disable or drop parition of the table all together (convert the table to a non-partitioned table) and then I can re define the parition function again.
Any ideas?

Is it possible to use a variable to specify the filegroup in the ALTER/CREATE PARTITION SCHEME command?
I want the partition scheme to use the default filegroup for ALTER and CREATE PARTITION SCHEME. At the time the script is created, I don't know the default filegroup in the database.
My code:
declare @fileGroupName VARCHAR(50) = (select top 1 name from
sys.filegroups where is_default = 1)
ALTER PARTITION SCHEME MyScheme NEXT USED @fileGroupName
Is failing:
Incorrect syntax near '@fileGroupName'.
Q: Is it possible to use a variable for the filegroup in the ALTER/CREATE commands? Is so, what is the correct syntax?
Q: If using a variable is not possible, is there another way to specify the default filegroup?

I am using a WriteBack Partition to receive data from various inputs and appends any new data that I add to the WB partition.Â
I am able to read the data immediately in the WB partition through a Fact partition query. This is working at this point as desired.
Eventually I want to move the data from the WB partition into Fact Partition. How can I do this, manually and through automation.Â

Guys,
I have names in the database which I want partition by last name - for example last names starting with A, B, C, D should go to the file group 1. last names starting with E, F, G, H should go to file group 2.
I am trying to use the following function - but do I specify in the function that last names with with A, B, C, D should go to the file group 1
CREATE PARTITION FUNCTION myRangePF3 (char(20))
AS RANGE RIGHT FOR VALUES ('EX', 'RXE', 'XR');
Is there any way to modify partition function to accomplish this?
Any suggestions and inputs would help
Thanks

It is first time that I'm having this problem; I had developed an application which has been deployed on client's computer. Now he requested for some changes in application for which i have to change the tables structure as well as lot of coding too. What i am worry about is that if i make changes to the structure of tables so how i will incorporate the old data (the client has started working upon the application)into this newly structure tables because this newly structured tables will have more or less columns than the previous one.
My table for the time being is:
SaleID (Primary Key)
SaleTotalAmount
SalePaidAmount
SaleDiscount
SaleNetBalance
SaleDate
And fields have to incorporate are:
SaleTotalProfit
SaleTotalLoss
I ran the alter query and it worked fine for me. But the problem is that If i give this new DB to client, so how i will incorporate the old data into this newly altered DB?
Let me briefly explain my application. I developed a standalone PC application where both DB and application are installed on a single PC.

I would like to set a field to not null which I can do like this: ALTER TABLE table1 ALTER COLUMN field1 BIGINT NOT NULL
My question is there anyway to set this field to NOT NULL without having to specify the data type BIGINT? I'm using dynamic sql and if there was a way then I wouldn't need to go get the data type of the field dynamically and it would save me a step. Thanks.

I am facing issue in generating total sum and daily sum from table ThresholdData.
DailyTransactionAmount should be sum of todays amount in the table
TransactionAmount should be sum of all amount in the table.
Basically,
1. I don't want to scan ThresholdData table twice.
2. I don't want to create temporary table/table variable/CTE for this.
3. Is there is any way to make it done in single query.
I hope, where criteria is not possible in partition function. I am trying query something as given below,
SELECTÂ Â TransactionDate,
  TransactionAmount,
  ROW_NUMBER() over (order by TransactionDate) AS TransactionCount,
  SUM(TransactionAmount) over (partition by id ) AS TransactionAmount,Â
  SUM(TransactionAmount) over (partition by id ,CONVERT (DATE, @TodaysTransactionDate)) AS DailyTransactionAmount
 FROM ThresholdData
 WHERE id = @id
 AND transactiondate >= dateadd(d,-@TransactionDaysLimit,@TodaysTransactionDate)

I have a requirement of table partitioning. we have 10 years of data on a table which is 30 billion up rows on 2005 server we are upgrading it to 2014. we have to keep 7 years of data. there is no keys on table or date column. since its a huge amount of data and many users its slow down the process speed. we are thinking to do partition on 7 years for Quarterly based. but as i said there is no date column on table we have to use reference table to get date. is there a way i can do the partitioning with out adding date column on table? also does partition will make query faster?Â
I have think three ways to do it.
1. leave as it is.
2. 7 years partition on one server
3. 3 years partition on server1 and 4 years partition on server2 (for 4 years is snapshot better?)

DECLARE @DatePartitionFunction nvarchar(max) = N'CREATE PARTITION FUNCTION DatePartitionFunction (datetime) AS RANGE RIGHT FOR VALUES (';
DECLARE @i datetime = '2007-09-01 00:00:00.000';
WHILE @i < '2008-10-01 00:00:00.000'

[Code] ....
Msg 7705, Level 16, State 2, Line 1
Could not implicitly convert range values type specified at ordinal 1 to partition function parameter type.
However if I change to datetime2 it works
DECLARE @DatePartitionFunction nvarchar(max) = N'CREATE PARTITION FUNCTION DatePartitionFunction (datetime2) AS RANGE RIGHT FOR VALUES (';
DECLARE @i datetime2 = '2007-09-01 00:00:00.000';

BEGIN
SET @DatePartitionFunction += '''' + CAST(@i as nvarchar(10)) + '''' + N', ';
[Code] ...
Is the data type of the column used for partitioning. All data types are valid for use as partitioning columns, except text, ntext, image, xml, timestamp, varchar(max), nvarchar(max), varbinary(max), alias data types, or CLR user-defined data types.
In this case why isn't datetime works?
version is as follow:
Microsoft SQL Server 2012 (SP1) - 11.0.3128.0 (X64)

Enterprise Evaluation Edition (64-bit) on Windows NT 6.1 <X64> (Build 7601: Service Pack 1)

Table and index partitioning is supported in this edition
so I don't know why it fails!

Hi,
I am new to SQL 2005. I have to design schema for scientific data warehouse. Data is available in 2 or more flat data files recorded at 1 sec interval. At Least 2 of the data files have 100+ columns. I am inclined to create a table per data file type. I want to know If this is correct/optimal for me to do?
I don't think I can create normalize tables based on the headers in these Data files.
Primary Objective of this data warehouse is make it available for reporting services and Analysis Services.
Any suggestions or tutorials for me?
Thanks,

I have data that is similar in nature to stock market data. There are about 100 entries per day. I would like to setup a second table to supply chart information. (assuming 1000 pixels per chart max)Â
What is the best way to condense the information in this table so that if I query for a chart, the table returns about 1000 points? I could have several tables setup, one for short term, and one or two for longer term. But I still don't know how to condense them.Â

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.
