Partition Function - Unknow Range Column
May 4, 2006
Hi,
I need to create a partition table but the column on which I need to
create a partition may not have any logical ranges. So while creating
or defining partition function I can not use any range.
like
CREATE PARTITION FUNCTION my_part_func (NUMERIC(7)) AS RANGE LEFT FOR
VALUES (1,100,1000);
Is there any way to define partition function in SQL Server something
like Oracle HASH partitions where logical range is unkown?
Thanks

Hello All,
I am using SQL 2005 SP2. I have a table partitioned on date range. I am trying to SWITCH, MERGE and SPLIT partitions.
My SWITCH and MERGE work great. When the SPLIT query is executed, an error 9002 is thrown....
"The transaction log for database is full. To find out why space in log cannot be resued, see log_reuse_wait_desc column in sys.databases."
Below are more details...
- All SWITCH, MERGE and SPLIT are executed in one TRANSACTION.
- After SWITCH and MERGE, I execute a query set the partition scheme "NEXT USED [PRIMARY]".
- Finally i execute SPLIT statement.
Could you please tell me where am I going wrong?
Any help would be appreciated.
Thanks..................

Is it possible to show the number of rows and the range for each partition in a table ?
This shows me the range but not the row count per partition
SELECT sprv.value AS [Value], sprv.boundary_id AS [ID] FROM sys.partition_functions AS spf
INNER JOIN sys.partition_range_values sprv
ON sprv.function_id=spf.function_id
WHERE (spf.name=N'myDateRangePF')
ORDER BY [ID] ASC

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

I can't seem to find a way to do the following:create table part_table (col1 int,col2 datetime) on psX (datename(week,col2))I want to partition based on the week number of a date field.So if I enter in data like the following in my part_table:(1, 1/1/2007) should go into partition 1 for week #1(52, 12/21/2007) should go into partition 52 for week #52 of the yearI tried adding in a computed column, but it says its nondeterministic.

Am I correct in assuming, in partitioning scenarion - the NUMBER OF PARAMETERS in a partitioning function is equal to number of file groups?

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,
SELECT TransactionDate,
TransactionAmount,
ROW_NUMBER() over (order by TransactionDate) AS TransactionCount,
SUM(TransactionAmount) over (partition by id ) AS TransactionAmount,
SUM(TransactionAmount) over (partition by id ,CONVERT (DATE, @TodaysTransactionDate)) AS DailyTransactionAmount
FROM ThresholdData
WHERE id = @id
AND transactiondate >= dateadd(d,-@TransactionDaysLimit,@TodaysTransactionDate)

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?

DECLARE @i datetime = '2007-09-01 00:00:00.000';

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';

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:

Table and index partitioning is supported in this edition

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.

I am trying to get the last 60 days before a month starts. I have a set that is returned from the query below :
SELECT
non empty
[Measures].[TRANSACTIONS Count] on 0,
non empty ([TRANSACTIONS].[Days].[Days],
[TRANSACTIONS].[Transaction Month].[Transaction Month]) on 1 from [cube]
I can get the cummulative count of last 60 days before month 2 by hardcoding the day of transaction of start of month like below :
WITH MEMBER
[Measures].[Cumm Account Count]
AS
(
AGGREGATE( [TRANSACTIONS].[Days].CurrentMember:NULL ,[Measures].[TRANSACTIONS Count])
)
SELECT
non empty [Measures].[Cumm Account Count] on 0,
non empty [TRANSACTIONS].[Days].&[3]:[TRANSACTIONS].[Days].&[3].lead(60) on 1 from [cube];
and for subsequent months by using the dates that the following month starts. How can I achieve the above result without having to use the day numbers, I tried to use the tail function (to get the months and star date) but it wont work because the range function accepts members only...

If I run an UPDATE query on a table which is partitioned by the column I am updating - will the records be moved to another partition?
ie. I have a table where Historical bit column marks whether a particular record should go to Partition1 (=0) or Partition2 (=1). Now, I update a record in that table and change the Historical column value from 0 to 1. What happens with that record?

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.

I need to import some data into a table that is in a merge bi-directional publication. The table has an identity column that is being "auto managed". The ID numbers I need to import are not within any of the assigned "ranges". They are less than any of the current ranges.
Turning ident_insert on does not work because of the check constraints error. The merge replication triggers validate the ID range as well.
Edit: using SQL 2005 standard publisher and subsciber. Publication is 2005.

HI all -
I need to group data in a sql report by currency values. I have a report that shows part numbers and 4 columns making up manufacturing costs and then a 5th column showing total costs. I would like to add a 6th column that groups the total costs by ranges. The example would be, group all costs > 20000, group all costs 1000 > x > 20000 , and finally all costs < 1000.
How can I accomplish this?

I'm using SQL Server 2000 sp2...I have created a view that gives me customer info from which I need to create a view and or table that gives me a 24 monthly columns of the sum of each account_number monthly revenues (going back 24 months from this month)..The columns I'm pulling from are these:
Customer_Name
Account_number
First_insert_date
Order_net_price
Here's what I have so far:
----------------------------
SELECT TOP 100 PERCENT Account_number, Customer_Name, SUM(Order_net_price) AS 'CM - 24'
FROM dbo.Customer_Feed
WHERE (First_insert_date >= DATEADD(mm, DATEDIFF(mm, 0, GETDATE()) - 24, 0)) AND (First_insert_date < DATEADD(mm, DATEDIFF(mm, 0, GETDATE()) - 23,
0))
GROUP BY Account_number, Customer_Name
ORDER BY Account_number
I've basically hacked out a way to get the monthly totals for each account. What I would like to do is so be able to repeat the query but increment the date range 1 month until reaching the present or last FULL month and display these sums in individual columns named CM - n (where CM means current month and 'n' is the # of months back from current.how to make this query run over again the 23 other times I need it to and display those months sum totals in individual columns.

I have column which stores People count based on department, Now I want to keep them in the batch of 1000, If the running summary of (No of people) from departments reached 1000 then it should start sum(no of people) from 0 to 1000
Is there any running summary kind of function which can start sum record with in range of 0-1000
For Ex. My Data stored like this
Dept People Count
CSE 200
IT 250
EEE 312
ECE 214
MEC 337
Batch Grouping
Dept People Count BatchSum
CSE 200 200
IT 250 450
EEE 312 762
ECE 214 976
MEC 337 337 (Note here since its crossing 1000, its resetting and starting summary)
I implemented this with While Loop & if condition, But its very slow, is there any other way to achieve it in better way.

I have several databases to deal with, all with + 250 tables. The databases are not identical and do not conform to a specific naming convention for table names. Most but not all tables have a column called "LastUpdated" containing a date/time (obviously). I'd like to be able to find all rows within a whole database (table by table) where the date/time is greater than a specified date/time.
I'm looking for a reliable query that will return all the rows in each of the tables but without me having to write hundreds of individual scripts "SELECT * FROM [dbo.xyz] WHERE LastUpdated > '2015-01-01 09:00:00:000'", or have to look through each table first to determine which of them has the LastUpdated field.

This is the code I have written and I am trying to retrieve minimum count of PQpageId for every hour for a given date of range.
WITH CTE AS (
SELECT PQIM.PQPageID
,PQIM.PageURL as PageDescription
,CONVERT(Date,NCPI.RequestDateTime) AS [Date]
,DATEPART(HOUR,NCPI.RequestDateTIme) AS [HOUR]
,ISNULL (COUNT(NCPI.PQPageID),0)AS HourlyPQPageIdCount
FROM dbo.NewCarPurchaseInquiries AS NCPI WITH (NOLOCK)
[Code] ....
This is the output I get :
PQPageId Date HOUR MINCOUNT
-------- ---------- ---- --------
1 04-11-2015 8 2359
1 05-11-2015 8 2332
1 06-11-2015 8 2008
1 07-11-2015 8 1964
1 08-11-2015 8 2139
1 09-11-2015 8 54
[Code] ....
But I am expecting
PQPageId Date HOUR MINCOUNT
-------- ---------- ---- --------
1 09-11-2015 8 54
1 11-11-2015 9 10
1 11-11-2015 10 4
2 11-11-2015 8 10
2 11-11-2015 9 2
2 11-11-2015 10 1
For ex: Pqpageid 1, at 8am on date 4-11-2015 has a count of 2359 and on 9-11-2015 at 8 am it has count 54then it should return date 9-11-2015 and count 54 for hour 8 like wise for every pageid and hour from 8 to 23 it should return the min count from given date of range.

Any ideas how can I pass date range values from the where clause of an outer query to the inner correlated subquery ... without using a stored procedure because I am using Report Builder?
Using the simplified sql below I need the average freight charge between the dates for all of the ShipCountry's orders. (I have hard coded the dates for demo purposes only as it is these that I need referenced from the outer query's where clause.)
select
OrderDate,
ShipCountry,
ShipCity,
Freight,
/* how do I get to the outer query's date range ? */
(SELECT AVG(Freight) FROM Orders WHERE ShipCountry = O.ShipCountry AND OrderDate between '01-jan-1997' and '01-jan-2000') AS CountryAverageFreight
from
Northwind.dbo.Orders O
where
ShipCity = 'Paris' and OrderDate between '01-jan-1997' and '01-jan-2000'

We replicate a SQL2000 database (DataBaseA) to a SQL2000 database (DataBaseB) by using the Restore function and hasn't change its logical name but only the physical data path and file name. It is running fine for a year. We use the same way to migrate the DataBaseB to a new SQL2005 server with the Restore function and the daily operation is running perfect. However, when we do the Backup of DatabaseB in the SQL2005, it just prompt the error message
System.Data.SqlClient.SqlError: The backup of full-text catalog 'DataBaseA' is not permitted because it is not online. Check errorlog file for the reason that full-text catalog became offline and bring it online. Or BACKUP can be performed by using the FILEGROUP or FILE clauses to restrict the selection to include only online data. (Microsoft.SqlServer.Smo)
Please note we left the DataBaseA in the old SQL2000 server.
Please help on how we can delete the Full-text catalog from DatabaseB so we can do a backup
Many Thanks
