Am I correct in assuming, in partitioning scenarion - the NUMBER OF PARAMETERS in a partitioning function is equal to number of file groups?
------------------------
I think, therefore I am - Rene Descartes
partition with single file group or multiple file group which one best.
we have some report running from partition table, few reports don't have any partition Key and after creating 400 partition with 400 file group it is slow.what is best practices to crate 400 file group or single file group.
If I have the first two columns from a SQL query and would like to create the third (row):
personid new_commsstream row
1 0 1
1 0 1
1 0 1
1 1 2
1 0 2
2 0 1
3 0 1
4 0 1
5 0 1
5 1 2
5 1 3
Is this possible? I have tried using row over partition but I'm not sure how group it correctly, so basically every time there is a new 1 in new_commsstream within a personid the row number goes up by one.
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.
View 4 Replies View RelatedI 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,

Hi,I need to create a partition table but the column on which I need tocreate a partition may not have any logical ranges. So while creatingor defining partition function I can not use any range.likeCREATE PARTITION FUNCTION my_part_func (NUMERIC(7)) AS RANGE LEFT FORVALUES (1,100,1000);Is there any way to define partition function in SQL Server somethinglike Oracle HASH partitions where logical range is unkown?ThanksSameer

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?

I have a heavy database , More than 100 GB only for six month .every Query on it takes me along time and I dont have enough space to add more indexes.by a way I decided to do partitioning. 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?
View 9 Replies View RelatedI'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.

Hi All,
I would like to know if that the SUM() function can use more than 1 group in the scope portion. Example is as below:
Sum(Fields.Hour.Value, ("grp1", "grp2"))
This would help as I am doing a report using a matrix report. I need to do a calculation in the measure area so that it will calculate base on the row and column grouping. Is this possible?
Thanks & Regards,
Fadzli
can anyone tell me what is the use of group by in rs tables and how to use group by in tables (when we have to use )...if possible please gimme some examples..
Hello,
I column that calculated at run time in insert , can i gruop by this column,the new one that not exist yet
I want to run a much larget SQL statement, but for examples sake this is a good starting point
Code:
Select efName, elName, eAddress, SUM(Convert(money, bonus1)+Convert(money, bonus2)+Convert(money, bonus3)) As TotalBonus, ePay FROM tableEInfo
It is telling me that I have to use Group By, but the problem is that most of my fields are text fields, which it looks like have to be converted in order to use with a group by statement. Is it possible to use the sum function with no group by statement?

group by empid,year(orderdate)
sample data resultset:
empid orderdate

why is the year() gets only one year when worked with groupby. when empid =1 the year 2007 has 2 records and 2008 has 2 records in first select and when I used year(orderdate) in secong select only one year for each is selected.

For a database, we have 4 data files in a particular file group and the file sizes are almost 70 GB each.
Do I come across any performance issues if I create/pre-allocate an additional data file in the same file group so that the existing files don't grow too much?

The SELECT on SRTAS is to get the "description" of STATI.Z4414 who's stored in the table SRTAS.

This query is dynamicly generated from within my program from what the user selected.
Also, if there are better ways to write the query, I would be happy to get some hints and tips, but if possible without stored procedures.
Thanks in advance!

Why shrinkfile empty file does not redistribute data evenly in the primary file group with multiple files:
Please run the script attached to see what the end result is.
This is what I set up last night on my test machine.
1) Create database [FGTest] size 200MB
2) Create table called TEST on primary
3) Insert 40MB of data into test
4) Create another file group called temp in primary size 200MB
5) Shrinkfile('FGTest',emptyfile) so that all data is transfered from FGTest into temp file group.
6) Add another 2 files called DATA2 and DATA3. Both are 200MB.
7) We now have 3 empty files that I want data distributed evenly on. FGTest, DATA2 & DATA3
8) Shrinkfile('temp',emptyfile) to move all the data from temp over the 3 file groups evenly
I would expect at this stage to have the following:
FGTest = 13MB,
DATA2 = 13MB,
DATA3 = 13MB
(40MB of data over 3 files should be about 13 MBish in each file)
What I actually end up with is this:
FGTest = 20MB
DATA1 = 10MB
DATA2 = 10MB
It looks as though SQL Server is allocating 50% of all data to the original file and then 50% evenly over
the remaining files in PRIMARY.

Consider the following dataset:

5 | FD | DR. A | Y
6 | PF | DR. A | Y
7 | FD | DR. B | Y
8 | PF | DR. B | N
Consider the script below:
SELECT
COL2, COL3, COUNT(COL1) AS TOTALS
FROM CASES
GROUP BY COL2, COL3
ORDER BY COL3, COL2
The script above produces the following output:

FD | DR. B | 1
PF | DR. B | 1
