Horizontal Partitioning Question
Jul 20, 2005I recently came across a database where the data are horizonally partitionedinto 4 tables. I'm not sure if this was a poor design choice, or if it wasdone for valid performance reasons. The schema of the tables are essentiallythe same, it's just that they are named differenly and the columns are nameddifferenlty to differentiate the data from a business usage perspective. Thetables could easily be combined inot one by adding a new colum to theclustered index that would be used to differentiate the business usage. I amtrying to evaluate whether combining the tables would improve performance orif it would be better to leave them the way they are. Many queries that runagainst these tables do not request records from more than one of thetables, which is good. However, there are a number of processes that queryagainst all of the tables on the identical clustered index range. I am notsure exactly how many rows are in the tables but I'm fairly certain theentire database is < 50 GB.

Jan 17, 2001HI, I'm testing out partitioning for an upcoming project and I'm a little confused over the query plan im generating.
I have a 13 million row table I want to break in to date ranges:
tables are calljrnl,calljrnl_1999 and calljrnl_2000. The calljrnl table contains data for the last six months. one view, calljrnl_view is a union all of these three tables.
alter table calljrnl add constraint dt_constraint check (cj_created_dt >= '2000-10-01 00:00:00')
alter table calljrnl_1999 add constraint dt_constraint_1999 check (cj_created_dt <='1999-12-31 23:59:59')
alter table calljrnl_2000 add constraint dt_constraint_2000 check (cj_created_dt >='2000-01-01 00:00:000')
alter table calljrnl_2000 add constraint dt_constraint_2000_2 check (cj_created_dt <='2000-09-30 23:59:59')
The problem I'm having is that when I query on any date range outside the constraints set on the calljrnl_2000 table, It still wants to scan the calljrnl_2000 table.
I'm assuming this has something to do with how the constraints are structured, but I am not able to find the right combination.
ALL HELP IS GREATLY APPRECIATED!!!!
How Do I ... Loop Horizontal??
Feb 3, 2005If I have the raw data dumped into a big table as following:
Date P R M E Date P R M E Date P R M E Date P R M E
1/1/90 1 2 3 4 1/1/90 2 3 4 5 1/1/90 3 4 5 6 1/1/90 4 5 6 7
...
1/1/05 1 2 3 4 1/1/05 2 3 4 5 1/1/05 3 4 5 6 1/1/05 4 5 6 7
And this table has a repeating block [D, P, R, M,E] 300 times. Is it possible to write a loop query/stored procedures/triggers (or whatever it is) to read each repeating block and stack them on top of each other to insert into another table which has the same structure as following?
Look like this?
Date P R M E
1/1/90 1 2 3 4
...
1/1/05 1 2 3 4
1/1/90 2 3 4 5
...
1/1/05 2 3 4 5
1/1/90 3 4 5 6
...
1/1/05 3 4 5 6
If there is a solution would you please elaborate, example?
Thank you for the help.

Wewill be setting up this server on a SAN array that will be made up ofjust one or two huge virtual RAID10 volumes and I am also wonderingabout the wisdom of this? Its simple and should work, but is thatconfig relevant in any way specifically to our plan to partition?

Horizontal Partitions - Not Working As Described
Apr 16, 2002I am testing horizontal partitions to see whether it is a feasible
option for a project. IF I have a composite Primary Key and the
constraint column (a part of the Primary Key) that helps the
partitioned view is defined with DateTime Data Type, select on a restricted set of data through a partitioned view still tries to access all the tables instead of just one table that contains the data. Is this the case or am I
missing something ?
Any help on this is appreciated.
Here is what I am trying to do.

Horizontal To Vertical Array?
Nov 29, 2012I'm running SQL Server 2008 Standard.I need to create a query that has data from multiple columns (Columns 1-6 with coresponding Date started and Date Completed data) displayed vertically, but also has the column name the preeceeding column to identify it...along with other data (Record number, status).
Record Number, Status, Column Name, Date Started, DateCompleted
1, Open, Column 1, 1/1/2012, 2/1/2012,
2, Hold, Column 2, 1/3/2012, 3/1/2012,

Update Horizontal Partitions
Feb 24, 2004I'm considering using horizontal partitions to separate my data by year.
For example, SomeTable_2004, SomeTable_2003, etc. This works well for backups, maintenance, etc. because I'm working with 150+ GB of data. I'll be a partitioned view for queries.
However, I'm new at this and have a few questions. I would also like to do partitioned updates or inserts. But I need to make sure that the tables don't use similar primary keys. Does that make sense? I need to make sure that the primary keys from the first table are not used again in the second table.
SomeTable_2003
primary keys: 1,5,8,9,15
SomeTable_2004
primary keys: 2,3,4,10
I don't really care what keys are used on what table, as long as they are different. I have apps that already use this data, and I don't want to change the application logic.
Thanks,

Horizontal Data Restriction
Jul 20, 2005I have 2 installations:1. W2k with MS SQL 2000 sp2.2. W2003 with MS SQL sp3.There are two databases in all instalations: "maindb" and "userdb". Thetable with data is in maindb.In the 1'st installation I restict user access to all data in table in thisway:- create user's login and user in databases maindb and userdb.- create view in userdb with "where" clause as dbo (dbo is owner of thisview). This clause restict access to data. (create view userdb.dbo.table asselect * from maindb.dbo.table where ...)- add user to group "Public" in maindb.- add role "data reader" to user in userdb.- effect: user can access data only by view, can not access any data inmaindb.I do the same in secound installation:- effect: user can not access data by view - message like this: "userhave not permission to select on maindb.dbo.table"Is this bug in sp3 or in sp2 ?Is there another way to horizontal restrict access data in tables?In Sybase ASE this method (restict by view) works ok. And there is newproperty of ASE 12.5.1 - administrator can define context of login - the"where" clause will be added automatically to any select.Please help me. Thank You for any advice.

Converting Vertical Data To Horizontal
May 25, 2006I have a table as follows
opendate (datetime) callnumber (int) closed (bit)
I want to find how many calls were opened today and of those how many are closed
I have come up with the code below but again am looking for
1. a more elegant solution
2. a way to generalise this to show the same information for x number of days
create table #holdit1
(opencount int)
create table #holdit2
(closedcount int)
insert into #holdit1
SELECT count(*) as opencount
FROM [dbo].[problog]
WHERE datediff(dd, opendate, getdate()) = 0
AND closed = 0
group by closed
insert into #holdit2
SELECT count(*) as closedcount
FROM [dbo].[problog]
WHERE datediff(dd, opendate, getdate()) = 0
AND closed = 1
group by closed
select #holdit1.opencount AS CallsOpen, #holdit2.closedcount AS CallsClosed, #holdit1.opencount + #holdit2.closedcount AS AllCalls
from #holdit1 cross join #holdit2 #holdit2
DROP TABLE #holdit1

Automatic Horizontal Width For Column
Feb 14, 2008Hello,
We are generating RDL file on the fly using a XSLT. We are trying to implement an auto width to all the columns dislpayed in the Report. Is Automatic horizontal width for column supported in RDL? If so how? If not is there is any workaround for it?
We tried using CanGrow and CanShrink tags, but those are for only vertical.
Thanks in advance.
Horizontal Display For Tables Or Lists?
Jul 5, 2007I would like to display a couple of records horizontally via a table or list, but don't think this is possible. Am I right? The given recordset should only have two records and the formatting would be much better if they were displayed left to right rather than one on top of the other. Is this just not possible with SSRS? Thanks,

Horizontal Totals Of Subtotals In A Matrix
Sep 19, 2007I'll admit I am fairly new to the reporting services, but I managed to figure most things out so far except this one. I have a matrix report where I have column groupings of:
Sales person
Region
Basically, the report shows sales by sales person and region, and I added subtotals to each so each salesman/region combination gets subtotals, as does each salesman entry. Now, the one piece missing is the 'total of the subtotals' so to speak. So if I have something like:
Salesman Region Sales Jan Sales Feb Sales Mar
001 A $100 $175 $50
B $100 $200 $100
C $200 $100 $50
Total $400 $475 $200
002 A $100 $175 $50
B $100 $200 $100
C $200 $100 $50
Total $400 $475 $200
Grand Total $800 $950 $400
What I want to do is sum up the totals and add another column like so:
Salesman Region Sales Jan Sales Feb Sales Mar
001 A $100 $175 $50
B $100 $200 $100
C $200 $100 $50
Total $400 $475 $200 $1075
002 A $100 $175 $50
B $100 $200 $100
C $200 $100 $50
Total $400 $475 $200 $1075
Grand Total $800 $950 $400 $2150
And that is where I am stuck. In Report Designer, with the existing matrix report as above, how do I get these horizontal totals of the subtotals?

Have Query Results Display Vertical Instead Of Horizontal?
Apr 15, 2015I have a query that calculates sales by sales person, but it displays horizontally across my query window. Is their a way in SQL Server to have the data display vertically down the window instead?
This is my current query
Code:
Select
count(case when salesman Like 'Geo%' then id else null end) As [George]
,count(case when salesman Like 'Li%' then id else null end) As [Lisa]
,count(case when salesman Like 'Jor%' then id else null end) As [Jorge]
,count(case when salesman Like 'Ri%' then id else null end) As [Richard]
,count(case when salesman Like 'Geo%' then id else null end)+count(case when salesman Like 'Li%' then id else null end) As [Team 1 Sales]
,count(case when salesman Like 'Jor%' then id else null end)+count(case when salesman Like 'Ri%' then id else null end) As [Team 2 Sales]
from sales.southeastregion
Which of course shows the results as such
George --- Lisa --- Jorge --- Richard --- Team 1 --- Team 2
100 50 10 90 150 100
And I want the data to be displayed like
George - 100
Lista - 50
Jorge - 10
Richard - 90
Team 1 - 150
Team 2 - 100
This is SQL Server 2008 if that matters.

Column Group Footers In A Horizontal Report
Dec 14, 2006Hi all.
I've created a horizontal report using a matrix according to the quite useful article Horizontal Tables, but there's one thing I'm trying to do that I'm not having any luck figuring out how to do, and that is creating a footer column for a column group that contains a sum of the values in some of its columns.
In other words, here's how I would like to have it look...

The fields in the dataset are Month, Tier1, Tier2, Year and Quarter. I've created a group on Year & Quarter, tried right clicking and selecting Subtotal, but that seems to add a subtotal column after every month, not at the end of the quarter group as I want.
Any ideas on what I need to do? Is this even possible?

Horizontal Charts - Point Labels Issue
Dec 18, 2006Hi. I'm currently having some troubles with the Reporting Services charts and I was hoping I could get some help here.
The issue here is that I'm using charts with horizontal bars, and I can't seem to be able to control the alignment of the Point Values. I've read that the alignment can't be set while using stacked bar charts, but I'm not using a stacked bar chart, just a simple horizontal bar chart.
A workaround for this would be to use different colors for the values displayed outside the bars than from those displayed inside the bars (for better visibility). I had expected RS to display the values inside the bars when they are greater than a set percentage of the chart range (e.g. 95%). Alas, this is not the case, as it seems to consider the number of digits the values have AND the grouping. At least.
So, does anybody have an idea about what could be done in this particular situation?

Textbox Rotation Or Display Horizontal Vs Vertical
Jun 20, 2006Is it possible to align a text box to display text with rotation? For example can I display it rotated 90 degrees left so that it reads from the bottom towards the top of the page? All I can find is left/right alignment and top/middle/bottom alignment. I want to rotate the text.
Thanks.
