Architecture Question -- Grouping Different Kinds Of Stuff...
Aug 19, 2005
Hi all,
I'm hoping somebody here might be able to point me in the right
direction.
Basically, I'm looking for a "good" way to build tables such that
different kinds of stuff can grouped.
For example, let's say I have "rooms" and they can contain "people"
and/or "books" and/or "furniture" -- each of those objects (rooms,
people, books, furniture, etc) may have their own attributes -- but the
idea is that a room may contain 0 or more of each of the others.
I'll need to do lots of selects to retrieve the contents of specific
rooms.
Is there a standard / good way to go about this sort of thing?
Somehow giving people, books, furniture a room_ID (foreign key) seems a
bit clumbsy -- ie, do I have to run a select for each?
thanks kindly, -Scott

as i know, sql server states it can replicate oracle data to sql server. other than sql server itself, can it replicate other kinds of database like informix or sybase?

I'm really stumped on this one. I'm a self taught SQL guy, so there is probobly something I'm overlooking.
I'm trying to get information like this in to a report:
WO#
-WO Line #
--(Details)
--Work Order Line Detail #1
--Work Order Line Detail #2
--Work Order Line Detail #3
--Work Order Line Detail #etc
--(Parts)
--Work Order Line Parts #1
--Work Order Line Parts #2
--Work Order Line Detail #etc
WO#
-WO Line #
--(Details)
--Work Order Line Detail #1
--Work Order Line Detail #2
--Work Order Line Detail #3
--Work Order Line Detail #etc
--(Parts)
--Work Order Line Parts #1
--Work Order Line Parts #2
--Work Order Line Parts #etc
I'm unable to get the grouping right on this. Since the line details and line parts both are children of the line #, how do you do "parallel groups"?
There are 4 tables:
Work Order Header
Work Order Line
Work Order Line Details
Work Order Line Requisitions
The Header has a unique PK.
The Line uses the Header and a Line # as foreign keys that together are unique.
The Detail and requisition tables use the header and line #'s in addition to their own line number foreign keys. My queries ends up looking like this:
WO WOL WOLR WOLD
226952 10000 10000 10000
226952 10000 10000 20000
226952 10000 10000 30000
226952 10000 10000 40000
226952 10000 20000 10000
226952 10000 20000 20000
226952 10000 20000 30000
226952 10000 20000 40000
399999 10000 NULL 10000
375654 10000 10000 NULL
etc
Hierarchy:
WO > WOL > WOLD
WO > WOL > WOLR
It probobly isn't best practice, but I'm kinda new so I need some guidance. I'd really appreciate any help! Here's my query:
SELECT [Work Order Header].No_ AS WO_No, [Work Order Line].[Line No_] AS WOL_No,
[Work Order Requisition].[Line No_] AS WOLR_No, [Work Order Line Detail].[Line No_] AS WOLD_No
FROM [Work Order Header] LEFT OUTER JOIN
[Work Order Line] ON [Work Order Header].No_ = [Work Order Line].[Work Order No_] LEFT OUTER JOIN
[Work Order Line Detail] ON [Work Order Line].[Work Order No_] = [Work Order Line Detail].[Work Order No_] AND
[Work Order Line].[Line No_] = [Work Order Line Detail].[Work Order Line No_] LEFT OUTER JOIN
[Work Order Requisition] ON [Work Order Line].[Work Order No_] = [Work Order Requisition].[Work Order No_] AND
[Work Order Line].[Line No_] = [Work Order Requisition].[Work Order Line No_]

Hi all,
I'm running under Windows Server 2000 datacenter sp4 with sql server 2000 Sp4
on 16GB Ram.
I enabled the /PAE in the boot.ini file and also enabled the AWE and set the SLQ Server maximum memory to 6144.
Do I need to include the /3GB switch in the boot.ini file?
I'm a little bit confused with the article found on the site. http://support.microsoft.com/default.aspx/kb/274750
Here are the lines.
Use of the /PAE switch in the Boot.ini and the AWE enable option in SQL Server allows SQL Server 2000 to utilize more than 4 GB memory. Without the /PAE switch SQL Server can only utilize up to 3 GB of memory.
or-Use of the /3GB switch in the Boot.ini file allows SQL Server 2000 to use up to 3 GB of available memory.
Regards,
Larry

Hi,
You might just be able to save me downloading and installing SQL Server French...
I'm having localization problems with some .NET code - and I might be able to solve the problem if I know how SQL is parsed in different locales. Say my table MyTable contains a float column FloatColumn. In English, I would say
SELECT * FROM MyTable WHERE FloatColumn = 2.3
If my locale was, say for argument's sake, French, would I have to write
SELECT * FROM MyTable WHERE FloatColumn = 2,3
???
Thanks for your help,

Overview. Machine data is fed into DOWNTIMELOG via a Cimplicity. I do not have the ability to change the way that it goes in. It contains the time that a machine has stopped and where the stoppage has occurred. Via a web page I want to give the operator the amount of time the machine stopped. From that they will provide some more detail. As they enter time, I need to subtract what they entered from the total (DOWNTIMELOG). That is the reason I created ENTERED_TIME. [PDNTOTAL_TEMP_VAL0] hold the total time for each stoppage, [TOTTIME] is intended to hold the value that has been accounted for. [DWNCATEGORY_TEMP_VAL0] holds the category and matches up with [DWNCATEGORY]. Also, I need to match Date and Shift. The problem is that DOWNTIMELOG does not capture shift. However, 1st shift occurs between 700 and 1500, 2nd shift occurs between 1500 and 2300, 3rd shift occurs between 2300 and 700. 3rd shift presents a problem as it occurs across 2 dates. Could someone please help me with a query that provides the net between the two tables that is matched by date, shift and category?
CREATE TABLE [dbo].[DOWNTIMELOG] (
[timestamp] [datetime] NOT NULL ,
[DWNTIMESTAMP_VAL0] [varchar] (25) NULL ,
[UPTIMESTAMP_VAL0] [varchar] (25) NULL ,
[PDNHOUR_VAL0] [int] NULL ,
[PDNMIN_VAL0] [int] NULL ,
[PDNSEC_VAL0] [int] NULL ,
[PDNTOTAL_TEMP_VAL0] [int] NULL ,
[DWNMSG_TEMP_VAL0] [int] NULL ,
[DWNCATEGORY_TEMP_VAL0] [varchar] (50) NULL
CREATE TABLE [dbo].[ENTERED_TIME] (
[REC_ID] [int] IDENTITY (1, 1) NOT NULL ,
[DWNCATEGORY] [varchar] (50) NULL ,
[DWNMSG] [int] NULL ,
[ENTRYDATE] [smalldatetime] NULL ,
[SHIFT] [int] NULL ,
[TOTTIME] [int] NULL

Hello,I need to be able to replace only the first occurance of a space characterin a column.Reason being is the data in the column I am trying to replace seems to haveumpteen space characters after each entry, so a simple replace functionwill replace all the spaces after it with what I want!I have thought of RTRIM to get rid of the spaces after and then replace, Ihave also thought of CHARINDEX to find the first occurance of a space andSTUFF to replace it.I have done my homework on these functions!But I am having trouble writing such a statement,I've never written a query which would use more then one function on onecolumn you see and I am getting confused!I'll tell you what I want to do in simple stepsReplace only the first found space in a name column, but then if a name hasa middle initial that will be a problem,Replace that with a dot.then concatanate '@emailaddress;@emailaddress2' after itso when SQLServer does the select it will bring back something likejoe.bloggs@emailaddress;emailaddressBut I guess I'd also need joe.n.bloggs@emailaddress;emailaddressThe data in the column looks like this at the momentjoe bloggsBut I guess there may come a time when we havejoe n bloggs, just to complicate things!What is your advice, and how do I write a query like thisI have been playing around with it in Query Analyser but as I said I amgetting confused and need some help if you don't mindThanks a lot to all who reply :-)RegardsJayne

For example if I make a column not null the SQL Script generated.
Removes all indexes, keys, etc... than creates a temp tableThan moves the data into the temp tablethen deletes the old tablerenames the temp tableRecreate all the indexes, keys, etc...
Is there a structure reason for it? Like now that the DB is being alerted that the column is not null it wants to re insert all the data so it can re-organize it?
Because I can just write my own script to the effect of
ALTER [TABLE] [COLUMN] PARAM TYPE NOT NULLone line of script that seemingly does the exact same thing..
So I'm just curious when I change a column to non null why doesn't it just generate a simple one liner?

I have this query that calculates the next possible shipping day, based on 3 conditions:
- It has to be a workingday (WORKTIMECONTROL: 1 workingday, 0 holiday) - marked green
- There might be extra days (@xdays) required by the process - marked blue
- Customer wants their goods to be shipped on special days - marked red:select TOP 1 Transdate
from WORKCALENDARDATE
where Transdate > @startday and WORKTIMECONTROL = 1 and DATEPART(WEEKDAY,TRANSDATE)-1 in (2,4) and
[code]...
So customer 123456 accepts shipping of goods only on tuesday and thursday as in the above example "... in (2,4)". Multiple shipping days means that the Subquery returns more than one record, which gives me a headache as I don't see how to integrate this portion into my query. I tried to use the stuff function as I formally need a result that can be provided that way; but the format is incorrect as it in varchar, while an array of integer is needed.
DATEPART(WEEKDAY,TRANSDATE)-1 in (select stuff((select ',' + CAST(DELIVERYDAY as nvarchar) from CollectiveShipment where custaccount = '123456'
for xml path('')),1,1,''))

Hi,
This is probably for most of you a very basic question. My goal is to define in a seperate instance from application all infos related to DataSets and DataAdapters that are needed when connecting to a specific database. Why?
First, I would like to be able to have in a single instance everything needed when hooking to a SQL Server Express database and in an other everything needed when hooking to a SQL Server CE database. Then, from application, I would like to be able following a few basic configuration steps to choose from one or the other, or even both in specific cases.
Second, I want to be able to seperate Database related stuff from application so that I can re-use everything from any other application when needed.
I've read several books, articles on the subject and would like to have your opinion as several approaches were illustrated through them. What would you use for this:
- Component class?
- Class library?
- or else?
Any good articles on the subject?
Thanks in advance for sharing,
Stéphane

I'm implementing merge replication between SQL CE and sql server 2005 SP2. Here is the problem I'm facing
I have dynamic filters on some tables like
Select * from table1 inner join table2
ON table1.field1 = table2.field3
and table2.flag = true
When table2 flag turns true then all the matching records in table1 should be returned to the subscriber.
But that is not happening. The filter does not return any records to the subscriber even though i see records when i run the query on the server. My take on this is the publisher thinks there is no changes on table1 so there is nothing to update. So to fix that i run dummy updates like
update table1
set [name] = [name]
where table1.field1 in
(Select field2 from table2 where flag=true)
This updates the records and the publisher updates the subscriber the first time. When i set the flag to false, it is supposed to remove the data from the subscriber but i get this error.
The merge process failed because it detected a mismatch between the replication metadata of the two replicas, such that some changes could be lost leading to non-convergence. This could be due to the subscriber not having synchronized within the retention period, or because of one of the replicas being restored to a backup older than retention period, or because of the publisher performing more aggressive cleanup on articles of type download-only and articles with partition_options = 3. (Source: MSSQL_REPL, Error number: MSSQL_REPL-2147199363)
Get help: http://help/MSSQL_REPL-2147199363
The common generation watermark is invalid at this replica since it does not exist or metadata for changes not yet propagated may have been cleaned up. (Source: MSSQLServer, Error number: 21800)

I have no idea whats going on. Any clues, anyone? Thanks for your help.

I have a project. Originally when I created this project, I called it "Project_A", (and I did not create a solution directory).
Doing this created a folder called "Project_A" with the following files within it. I guess these are meta data files and I shouldnt be messing around with them. Anyway, I see
(1) Package.dtsx (The default package that gets created with a new project)
(2) Project_A.database
(3) Project_A.dtproj
(4) Project_A.dtproj.user
(5) Project_A.sln
(6) Project_A.suo
When I rename my project in the Solution Explorer to "Project_B", the following happens in my folder.
Everything remains the same except Project_A.dtproj gets renamed to Project_B.dtproj and a new file called Project_B.dtproj.user gets created.
Now, my questions.
Question 1: What if I wanted my folder to have the same name as my project? Can I just change the folder name in Windows Explorer without having any ill-behaviors later on? I always have 1 project to 1 solution so I want to use the convention of keeping my folder named the same as my project.
Question 2: What about the files that are still named with Project_A dot blah blah. Is it bad if I renamed these to Project_B dot blah blah?

A whole bunch of exciting new stuff announced around the Visual Studio Express Editions today. VS Express is now free for good, not just 1 year (just like SQL Server!). Also lots of great new content and fun projects to do.
See Dan Fernandez's blog posting at http://blogs.msdn.com/danielfe/archive/2006/04/19/579109.aspx for lots of details.

Hi everyone,
Primary platform is 64-bit on A-P cluster.
Our needs are on yearly basis and on monthly basis. We're forced to keep up five years for the majority of the production tables.
In terms of years, I see three ways:
1.Create all the ranges for a FILEGROUP with a only NDF
2004, 2005, 2006 => FG1 => ONE.NDF
2.Create all the ranges for a FILEGROUP along with more than one NDF.
2004, 2005, 2006 => FG1 => ONE.NDF
TWO.NDF
3.Create each range to a FILEGROUP where there will be one NDF or (n) NDF
2004 => FG0=> ZERO.NDF
2006 => FG1 => ONE.NDF
2005 => FG2 => TWO.NDF
What is the best approach in terms of availability, performance and best practices? Maybe is a silly question, I'm sorry if it is.
As usual, thanks a lot for your time.

I'm trying to do some basic stuff in SQL Server 2005 that I could do in Oracle. I'm sure there's a way to do these things, I just don't know how. My most immediate question is this:
Is there any easy way to run a SQL script and have it spool to HTML tables to a file? The 'results to text' from SSMS is not adequate for display purposes. I'm trying to display table/column descriptions.
Beyond that, does anyone know of any good resources that provide an 'Oracle to SQL Server' matrix so I can help figure out how to do some of these things in SQL Server?
Thanks in advance,
Mike

I have the following query that supposes to merge multiple result in a single one and put it into a temporary table:
SELECT DISTINCT [AlphaExtension],
STUFF((SELECT A.[NoteText] + '< BR />' FROM #temp A
WHERE A.[AlphaExtension]=B.[AlphaExtension]
FOR XML PATH('')),1,1,'') As [NoteText]
FROM #temp B
GROUP BY [AlphaExtension], [NoteText]
It is working fine unless by a simple detail. If you look at the second line of the query you will see that I am stuffing together a < BR /> tag (break line) because the contents of the field is going to be spitted directly to the screen and I want that the multiple results be displayed in different lines.
OK, the issue is that it is stuffing & lt ; BR / & gt ; instead < BR /> and therefore the browser is displaying the tag instead to break a line.

I have a column which needs to be 9 digits long. The first four digits are independent from the other digits. The following digits need to be 5 and I have to add leading zeros if they're less than 5. This is an awful design and I'd love to change it but I can't.
SELECT Cg.Fiid,
--Original Formula
SUBSTRING( CONVERT( varchar, Cg.Fiid ),1, 4 ) + RIGHT( '00000' + SUBSTRING( CONVERT(varchar, Cg.Fiid ), 5, 10 ), 5 ),
--My solution
STUFF(Cg.Fiid, 5, 0, REPLICATE('0', 9 - LEN(Cg.Fiid)))
FROM (VALUES(71927),

I think it was Pat Phelan who posted a little trick here where he used the STUFF function to create a string fo values from a column without using a cursor.
I am starting a brand new project and I did my table design and I am awaiting a finalized requirements document to start coding and I thought I would spend a little time writing some code to autogenerate some generic one record at a time SELECT, INSERT,UPDATE and DELETE stored procedures. With the coming holiday things are getting quiet around here.
The code that is not working is listed below. It does not work. It returns Null. I suck.
DECLARE @column_names varchar(8000)
SET @column_names = ''
SELECT @column_names = STUFF(@column_names,LEN(@column_names),0,C.COLUMN_ NAME + ', ')
FROM INFORMATION_SCHEMA.COLUMNS C
WHERE TABLE_NAME = 'MyTable'
SELECT @column_names
little help?

I downloaded the AdventureWorks2012 OLTP script. When I ran it it gave me some errors. I also noticed that it tried to install into the bult-in master database, it created a lot of tables and objects. Some questions :
1) How can I remove everything that the script installed into master database?
2) Do I need to create 1st an empty database and then run the script there?
3) I am running the script from a custom path (C:DownloadsMicrosoft SQL Server 2012AdventureWorks 2012 OLTP Script.zipAdventureWorks 2012 OLTP Script) not sure if this is causing some of the errors as the script, in the beggining has a path to other folders :
:setvar SqlSamplesDatabasePath "C:Program FilesMicrosoft SQL ServerMSSQL11.MSSQLSERVERMSSQLDATA"
-- NOTE: Change this path if you copied the script source to another path
:setvar SqlSamplesSourceDataPath "C:Program FilesMicrosoft SQL ServerMSSQL11.MSSQLSERVERToolsSamplesAdventureWorks 2012 OLTP Script"
4) Final question, I also downloaded the AdventureWorks 2012 simple database (AdventureWorks2012_Data.mdf). Is this file the same database as the one created by the OLTP script?
