I`m familiar with the sp_help_revdatabase stored proc which gives info on which devices a database is stored on. But I thought I`d heard of another sproc (or even a query of certain system tables) which could be used to determine the order of device creation for an entire SQL Server. The sysdevices table is fine, but doesn`t show the virtual device number, or whatever number indicates which devices were created first, second, etc.
Any suggestions?
We are running SQL Server 2014 Enterprise Edition (64-Bit) on Windows 2012 R2 Standard (64-Bit).
1. When to create indexes, before or after data is added? Please address Clustered and Non-Clustered Indexes.
2. To move indexes to it's own filegroup, is it best to create the NON-Clustered Indexes on the separate filegroup with code similar to the example below?
CREATE NONCLUSTERED INDEX IX_Employee_OrganizationLevel_OrganizationNode
ON HumanResources.Employee (OrganizationLevel, OrganizationNode)
WITH (DROP_EXISTING = ON)
ON TransactionsFG1;
GO
I have read the following links that states that if you create the Clustered Index on a separate filegroup, it would also move the base table to that particular filegroup. (So I take it that you ONLY can move NON-CLustered Indexes to a separate filegroup.)
Placing Indexes on Filegroups:
[URL]
By default, indexes are stored in the same filegroup as the base table on which the index is created. A nonpartitioned clustered index and the base table always reside in the same filegroup. However, you can do the following:
• Create nonclustered indexes on a filegroup other than the filegroup of the base table.
Move an Existing Index to a Different Filegroup:
[URL]
Limitations and Restrictions
• If a table has a clustered index, moving the clustered index to a new filegroup moves the table to that filegroup.
• You cannot move indexes created using a UNIQUE or PRIMARY KEY constraint using Management Studio. To move these indexes use the CREATE INDEX statement with the (DROP_EXISTING=ON) option in Transact-SQL.
I have a database in development in SQL Server 6.5 that needs to be occasionally deleted and rebuilt from a script when table structures are changed. I found that when very complex queries were performed, the 2 MB default size of tempdb filled up and returned errors, so I went to the Enterprise Manager to expand tempdb, learned that I had to first expand a device to expand tempdb into, and foolishly chose to expand tempdb into the same device space used by my application, instead of into one of the system databases. Now when I try to delete the device in preparation for its rebuild, the Enterprise Manager responds with an error message saying the device can't be deleted because it contains system tables. Is there any way to get the expanded portion of tempdb out of my application device so that the device can be deleted, without reinstalling SQL Server?

I used to get this problem in VS2003 sometimes and just like the numerous posts on different sites that I've looked at the problem eventually goes away and I'm none the wiser. One guy said that he found that if he went to bed the problem was resolved when he came back!
My PDA running Windows 2003 2nd Edition is directly connected to my PC via a USB port. I've rebooted my PC and done a soft reset on the PDA but it didn't help. I'm using ActiveSync 4.1.

We have an SSAS instance where when we run the query "select * from $system.discover_traces" the creation time in the resultset shows a different time from when we actually started the trace.
for example if we have create the trace at 3.30pm it shows 7.35 pm in the Sql server management studio resultset when we run the query "select * from $system.discover_traces".
Finding the "pieces of information" I need to successfully install the SQL Server Express edition is so complex. Uninstalls do "not" really uninstall completely, leading to failure of SQL install. Can you suggest a thorough, one-stop site for directions for the order of app uninstalls and then the order for app installs for the following...
SQL Server Express edition
Visual Studios 2005
Jet 4.0 newest upgrade
.Net Framework 2.0 (or should I use 3.0)
VS2005 Security upgrade
Anything else I need for just creating a database for my VS2005 Visual Basic project?
I was trying to use MS Access as my backend db but would like to try SQL Express

In SQL sERVER 2008, I have two fields - Depatment and Employees. I need to sort the result set by employee number ascending order, with following exception
1)when department number = 50 - the preferred order is Employee # - 573 followed by 551-572 (employee # belong to Dept 50 = 551-573)
2)When Department number = 20 – the preferred sort order is Employee # 213-220, followed by Employee # 201-213 (employee # belong to Dept 20 = 201-220)
How shall I achieve this?
I never paid much attention to this before but I noticed this today in a new table I was creating.
For tables defined in the tabular model the table properties have something like SELECT Blah FROM TableName ORDER BY Blah Then in the tabular model the table's data is in the same order it was ordered by in the data source for the table.
I have a date table I setup and I noticed it is NOT respecting the sort order.
I have it sorted by DateID which sorts with the oldest date first and newest date as last row.However, the table that is imported and stored in the data model is not in that order.
I can of course manually sort the rows in BIDS/DataTools, but I find this discrepancy odd.
Would this have negative impacts on the EARLIER function for example if the data rows are not in the order specified?
I have a query that calculate the total amount of order details based on a particular order:
Select a.OrderID,SUM(UnitPrice*Quantity-Discount)
From [Order Details]
Inner Join Orders a
On a.OrderID=[Order Details].OrderID
Group by a.OrderID
My question is what if I wanted to create a formula to something like:
UnitPrice * Quantity - DiscountAmount Where DiscountAmount = UnitPrice Quantity * Discount
Do I need to create a function for that? Also is it possible to have m y query as a table variable?
Hi!
I recently run into a senario when a procedure quiered a table without a order by clause. Luckily it retrived data in the prefered order.
The table returns the data in the same order in SQL Manager "Open Table"
So I started to wonder what deterimins the sort order when there is no order by clause ?
I researched this for a bit but found no straight answers. My table has no PK, but an identiy column.
Peace.

Hey guys, i need to find out how can i add order items under a Purchase Order number.
My table relationship is PurchaseOrder ->PurchaseOrderItem.
below is a Stored Procedure that i have wrote in creating a PO:
CREATE PROC spCreatePO (@SupplierID SmallInt, @date datetime, @POno SmallInt OUTPUT)
AS
BEGIN
INSERT INTO PurchaseOrder (PurchaseOrderDate, SupplierID) VALUES(@date, @SupplierID)
END
SET @POno = @@IDENTITY
RETURN
However, how do i make it that it will automatically adds item under the POno being gernerated? can i use a trigger so that whenever a Insert for PO is success, it automaticallys proceed to adding the items into the table PurcahseOrderItem?
CREATE TRIGGER trgInsertPOItem
ON PurchaseOrderItem
FOR INSERT
AS
BEGIN
'What do i entered???'
END
RETURN
help is needed asap! thanks!
hi basically what i have is 3 text boxes. one for start date, one for end date and one for order id, i also have this bit of SQL

but the problem is it does not seem to work! i am not an SQL guru but i cant figure it out, someone help me please!

Hi,
We got a problem.
supposing we have a table like this:
CREATE TABLE a (
aId int IDENTITY(1,1) NOT NULL,
aName string2 NOT NULL
)
go
ALTER TABLE a ADD
CONSTRAINT PK_a PRIMARY KEY CLUSTERED (aId)
go
insert into a values ('bank of abcde');
insert into a values ('bank of abcde');
...
... (20 times)
select top 5 * from a order by aName
Result is:
6Bank of abcde
5Bank of abcde
4Bank of abcde
3Bank of abcde
2Bank of abcde
select top 10 * from a order by aName
Result is:
11Bank of abcde
10Bank of abcde
9Bank of abcde
8Bank of abcde
7Bank of abcde
6Bank of abcde
5Bank of abcde
4Bank of abcde
3Bank of abcde
2Bank of abcde
According to this result, user see the first 5 records with id 6, 5, 4, 3, 2 in page 1, but when he tries to view page 2, he still see the records with id 6, 5, 4, 3, 2. This is not correct for users. :eek:
Of course we can add order by aid also, but there are tons of sqls like this, we can't update our application in one shot.
So I ask for your advice here, is there any settings can tell the db use default sort order when the order by column value are the same? Or is there any other solution to resolve this problem in one shot?
Hi,guys!I have a table below:CREATE TABLE rsccategory(categoryid NUMERIC(2) IDENTITY(1,1),categoryname VARCHAR(20) NOT NULL,PRIMARY KEY(categoryid))Then I do:INSERT rsccategory(categoryname) VALUES('url')INSERT rsccategory(categoryname) VALUES('document')INSERT rsccategory(categoryname) VALUES('book')INSERT rsccategory(categoryname) VALUES('software')INSERT rsccategory(categoryname) VALUES('casus')INSERT rsccategory(categoryname) VALUES('project')INSERT rsccategory(categoryname) VALUES('disert')Then SELECT * FROM rsccategory in ,I can get a recordeset with the'categoryid' in order(1,2,3,4,5,6,7)But If I change the table definition this way:categoryname VARCHAR(20) NOT NULL UNIQUE,The select result is in this order (3,5,7,2,6,4,1),and 'categoryname 'in alphabetic.Q:why the recordset's order is not the same as the first time since'categoryid' is clustered indexed.If I change the table definition again:categoryname VARCHAR(20) NOT NULL UNIQUE CLUSTEREDthe result is the same as the first time.Q:'categoryname' is clustered indexed this time,why isn't in alphabeticorder?I am a newbie in ms-sqlserver,or actually in database,and I do havesought for the answer for some time,but more confused,Thanks for yourkind help in advance!

I have created view by jaoining two table and have order by clause.
The sql generated is as follows
SELECT TOP (100) PERCENT dbo.UWYearDetail.*, dbo.UWYearGroup.*
FROM dbo.UWYearDetail INNER JOIN
dbo.UWYearGroup ON dbo.UWYearDetail.UWYearGroupId = dbo.UWYearGroup.UWYearGroupId
ORDER BY dbo.UWYearDetail.PlanVersionId, dbo.UWYearGroup.UWFinancialPlanSegmentId, dbo.UWYearGroup.UWYear, dbo.UWYearGroup.MandDFlag,
dbo.UWYearGroup.EarningsMethod, dbo.UWYearGroup.EffectiveMonth
If I run sql the results are displayed in proper order but the view only order by first item in order by clause.
Has somebody experience same thing? How to fix this issue?
Thanks,
I am getting the resultset sorted differently if I use a column number in the ORDER BY clause instead of a column name.
Product: Microsoft SQL Server Express Edition
Version: 9.00.1399.06
Server Collation: SQL_Latin1_General_CP1_CI_AS
for example,
create table test_sort
( description varchar(75) );
insert into test_sort values('Non-A');
insert into test_sort values('Non-O');
insert into test_sort values('Noni');
insert into test_sort values('Nons');
then execute the following selects:
select
*
from
test_sort
order by
cast( 1 as nvarchar(75));
select
*
from
test_sort
order by
cast( description as nvarchar(75));
Resultset1
----------
Non-A
Non-O
Noni
Nons
Resultset2
----------
Non-A
Noni
Non-O
Nons
Any ideas?

View 4 Replies View RelatedI noticed the StockDate is not sorted in proper order, like ascending order...
Code:
select top 1000 CONVERT(char, StockDate, 101) AS StockDate, timestamp from tblpurchaseraw where accountid = '119' order by stockdate desc
I noticed that StockDate is a datetime datatype so why does the month get ordered 1st, then day get ordered 2nd and year get ordered 3rd...
The sample data is MM/DD/YYYY...
So, how do I get it ordered propery by Year, Month then Day??
Lets say I have a table named [Leadership] and I want to select the field 'leadershipName' from the [Leadership] Table.
My query would look something like this:
Select leadershipName
From Leadership
Now, I would like to order the results of this query... but I don't want to simply order them by ASC or DESC. Instead, I need to order them as follows:
Executive Board Members, Delegates, Grievance Chairs, and Negotiators
My question: Can this be done through MS SQL or do I need to add a field to my [Leadership] table named 'leadershipImportance' or something as an integer to denote the level of importance of the position so that I can order on that value ASC or DESC?

Hi,
I have some hierarchical data in a table. Say for example:
Parent Child
------------------------
NULL 1
1 2
1 3
2 4
2 5
3 6
3 7
5 8
5 9
7 10
7 11
11 12
11 13
Now I want to be able to use CTE's to be able to traverse this tree in
1) level by level order 1,2,3,4,5,6,7,8,9,10....
2) in order 1,2,4,5,8,9,3,6,7,10,11,12,13...
What would be the aueries for this. Using the following i get: 1,2,3,6,7,10,11,12,13,4,5,8,9 (interesting and potentially useful) but I would like to be able to experiment with the aforementioned orders as well.
with Tree (id)
as
(
select id from WithTest
where parent is null
union all
select a.id
from Tree b join WithTest a
on b.id = a.parent
)
select * from Tree
Any ideas? Thanks.
Hi!
For the Orders table (let's assume for the Northwind database), I'm trying
to get the order id of the latest order for every customer.
That means that the result should be one record per customer and that would
display CustomerID and OrderID.
Any ideas?

Hi all, hope someone can give me some guidence on this.
We have a database on SQL 6.5 sp5a that is 25GB in size. The transaction log is 10GB in size. We do transaction log dumps every hour throughout the day. On a very heavy day the transaction log backup device will be just over 2GB in size. Around 8GB wasted because no-one knew how much space would be used.
Is there an easy way to resize the transaction log so we can reclaim some space. I was thinking of creating a new smaller database device, then using sp_logdevice to use the smaller device as the log and get rid of the 10GB device.
Any thoughts, ideas would be great.
Thanks

We have a 6.5 database that is comprised of 4 device files. As the database grows over time a new device is created for the space expansion. The last one was created on the wrong partition and the database was expanded onto it. I now need to move the device to the correct partition/directory. My question is; what is the easiest way to accomplish this move? Is it possible to move the device file and manually modify sysdevices? If so, what order of events should be followed?

I would like to free up some space on a SQL 6.5 server. My tempdb is on a second device (other than master) that is 500M. I don't need tempdb to be this large anymore. What would happen if I shut down SQL, renamed this device so that SQL Server wouldn't use it, and restarted SQL Server. Could I then create a new, much smaller device for tempdb? Would this work?
TIA!
