Asking For Advice
Aug 9, 2007
Hi everyone,
i wonder if any one can give me some advice.
here is my situation, i have a central database server that contains all the data, running in an intranet, the client application, which is a thick client containing most of the biz logics is installed on a laptop,
i m required to develop a solution so that when the client application is disconnect to the database server (e.g. the laptop is taken away somewhere) the application can still work and when the client application gets connect to the database server again the application will be able to synchronize changes with the database and update all the changes. and i m not allow to develop a web-base application
my initial thinking is to use merge replication, however, i m conerning with the performance on the laptop if i have to install sql server on the laptop.
is there any other approach that can still achieve the requirement and have a better performance?
thanks a lot in advance.

Hi
Dont laugh but...
I am not entirely ignorant to web technologies, and best practices but i am having a bit of a planning dylema.
My company has a well established SQL 2000 database with windows application which has been created by myself, what i am planning on doing is creating a web site, using asp.net and publishing some of the information, so that our clients may use it, and stop pestering us on the phone. what i would like to know is what would be the best way forward, obviously i don't want to show them all our information, and don't want to put 5Gb worth of data onto a ISP website. What would you suggest i do?
Thanks in advance

DECLARE @returnDay int
SELECT @returnDay = DatePart(day,GetDate())
If @returnDay = 8
BEGIN
select * from Hospitals left join Units ON Units.HospitalID = Hospitals.HospitalID where Units.HospitalID is null
RETURN
END
this is just a part of the procedure I am trying to create, I am getting hospitals that haven't submitted any data and wish to send them an email.
on the other hand I have two tables that have all the data for emailing to hospitals but are not linked to tables giving the list of hospitals
I have been advised to create a cursor(easier said then done) that will go through my list of records that need to receive an email
nothing going very well with that at the moment.
so I was hoping to see if somebody has any other suggestions for me.....

Hi,
I am trying to solve this procedure.
Let me try to explain it...I am getting DEGREEID from one of the SELECT query . I want to OUTPUT (ie , COUNT) from procedure,the number of departments with the degreeid, got from the above query.
With below procedure, Since an employee can have multiple DEGREEID , the cursor is giving OUPTUT ie, COUNT for the LAST Degreeid. Eventhough the previous DEGREEID dont have any DEPARTMENT...but only for the LAST DEGREEID...!
How can I solve this..... whether I can solve this with CURSOR or I have to use someother way...Please advice me !
DATA
-------
DEGREE_EARNED
---------------------
EMPID DEGREEID
------ ------------
201 12
201 3
201 250
202 3
202 10
203 17
DEPARTMENT
---------------
DEPID DEGREEID
------ ------------
10 1 12
111 250
111 12
121 3
121 12
121 250
------------------------------------
--------------------------------------------------------------------
DECLARE @vchid int
DECLARE testcursor CURSOR FOR
SELECT degree_id
FROM degree_earned WHERE emp_id= @empid
OPEN testcursor
FETCH NEXT FROM testcursor INTO @vchid
WHILE (@@FETCH_STATUS <> -1)
BEGIN
Select @outresult = COUNT(*)
from
department
where degree_id = @vchid
FETCH NEXT FROM testcursor INTO @vchid
END

Hi all,
My first request for help here even if I read this site quite often and got tons of usueful information. Thanx all
I have an application (VB 6) calling store procedure on a SQLServer 2000 DB. One of the table gives me headache. I wrote a simple store procedure to insert a record into that table. If I call the store procedure from query manager it works perfect but if I call it from VB it looks like to work (return from the execute fine) but then I query the table for that record and it'll just take time and then return time out. I have to stop the VB application and then query it again then it'll return no record.
I suspect the table being locked somehow but I check inside the VB app code and that's the only place the table is called. Further more I have hundred of store procedures being used that way and they're all ok. I indexed the table , no use either...
I am just short of ideas how to debug this...I'll need your advice :)
thank you

Okay, given my newness to SQL, and the complexity of this query, I thought I'drun this by you for your opinion:SELECT DISTINCT a.WeekEnding, c.lastdate, c.numlate, b.totaldateFROM Accomplishment a LEFT OUTER JOIN(SELECT weekending, COUNT(weekending) AStotaldateFROM AccomplishmentWHERE (EmployeeID = 50)GROUP BY weekending) b ON a.WeekEnding =b.weekending LEFT OUTER JOIN(SELECT weekending, MAX(entrydate) ASlastdate, COUNT(weekending) AS numlateFROM accomplishmentWHERE employeeid = 50 AND entrydate >weekendingGROUP BY weekending) c ON a.WeekEnding =c.weekendingORDER BY a.WeekEndingWhat I'm trying to do is for each pay period find which ones the employeesubmitted a timesheet and which they were late (and if they were late, howmany of them). However, the query takes a good 5 seconds, and it seemsremoving the "entrydate > weekending" clause speeds things up to almostinstant, however it does ruin the count that I really want. No idea whythat makes such a difference..

I have a couple of files that I have that are comma seperated, and am looking for the best way to take those files, but them in a temp location to run some sql up against, and than update or insert a production sql database based on a SP i have written that takes a number of variable. I have played around with using the recordset destination and defining all the variables and than using a for each loop but seem to be stuck. Somewhat new to the whole programming field, and to be honest, seems a little intimidating with the little I know of the programming side. Just looking for some thoughts.

Hello,
I am new to the CE OS, SQL CE and mobile computing in general. I have been developing database applications using MS products ever since Windows 3.11 and Visual Basic 1.0. I have used MS Access and SQL Server since they were first released. But, I have never worked with Windows CE or any of the mobile OSs or with SQL CE or SQL Mobile.
We now have a project that requires us to develop a database application on handheld devices using the CE 4.2 and CE 5.0 OSs.We will be using CF 2.0, VS 2005 and SQL 2005 for our development environment.
My questions are:
1. Which version of mobile SQL will allow us to best develop for both the CE 4.2 and 5.0 OSs usinf VS 2005? I have done a lot of reading online and it's pretty confusing. There are quite a number of different versions out there. It seems some work with 4.2 and some with 5.0. Is there a version that will work for both?
2. Is SQL CE 3.0 (Sql 2005 Mobile) available for other than Laptop and Tablet use? When i finaly got to the download page for this version there was verbiage there that suggested it was not available for smart devices.
3. What is a good source of info to resolve these questions? I am using the MSDN areas for CE and SQL Mobile but haven't really found what I need to get started. Any suggestions on forums, books, articles, blogs, etc... would be greatly appreciated.
I know these are very broad questions but I want to get some advice from the experienced before going to far here.

I just want to ask for any good advice here ragarding my project. I'm planning to create a program that will use an sql server as a database. I have 3 branches and I need the branches to be updated always when they create any transaction or changes. The sql server will be installed in a PC with Windows Server 2003 and with a public IP. the question is can I access the sql server from other branches by using the public IP of the ServerPC thru the Internet? If yes, how? if no, is there a best way to do this updating method?
Thanks!

Hi,
I am totally new to SQL and need to ask some basic questions.
Can anybody tell me if SQL 2005 will run ok on Windows Server 2008 32bit and/or 64bit.
Also, we are currently planning to implement OCS 2007 and we are considering running it on Windows Server 2008 32bit with SQL 2005. Does anyone know if this combination is possibleand if not what implementation should we be looking at.
Thanks for your time,
Cheers,

I'm creating a DB to track clients, programs, and client participation in the programs. They are service programs. A client can be in more than one program and a program can have more than one client.
Can someone give me an example of how they would layout the tables?
My guess is:
tblClient, ClientID
tblClientProgramLog, ProLogID, ClientID
tblProgramDetails, ProDetailID, ProLogID
tblPrograms, ProgramID, ProDetailID
I appreciate any suggestions,

Hello,I am creating a simple blog system using SQL 2005.I have a Blog table:[BlogId] > PostId (PK), BlogTitle, ...And a Posts table[Posts] > PostId (PK), BlogId (FK), PostContent, PostLabels, ...PostLabels would have the following format:Label1,Label2,Label3, etc ...I will need to perform 3 actions:1. Get all posts in blog2. Get all labels in a post3. Get all unique existing labels in all posts in a blog and make a list.I am not sure if my approach of using a simple labels column in my Posts table is a good idea.So my other idea would be to add two more tables:[BlogLabels] > BlogLabelId (PK), BlogId (FK), LabelName ...[LabelsInPosts] > BlogLabelId (PK), PostId (PK)So my idea is:1. When creating a post one of the parameters would be a comma separating string with all labels for the post. Inside SQL Procedure I will need to loop through each label and check if it exists in BlogLabels. If not then I added it. For each label I add a records in LabelsInPosts. How to create this loop? Am I thinking this right?2. To get a list of all labels in a blog I would need to go to BlogLabels and get all labels which are related with posts in LabelsInPosts. Those posts must be only the ones that are related with my given BlogId. Grrr, this is getting really confusing for me. Is this possible to to? How?Please, give me some advice about all this.Thanks,Miguel

Hi everyone,
My hoster hosts asp.net but does not yet support sql 2005 only sql 2000 and access I want to use either of the starter kits. I am confused on what is needed to make the changes to make either sql 2000 or access work. I know enough that the connection strings will need to change my concern is code. Is there strings that I will need to find and change in the application. I sure would appreciate any and all advice. Thank you for your help.

Hi,I recently contacted my hosting company's customer support about my databases not working - saying that I use sql express (which they support).The guy recommended:
"I would suggest you to upgrade the db's to use mssql 2005." "This
is because, sql express is built for development environment. When you
are in development environment, you are accessing everything with
administrator permission. However, in live hosting environment (when
there are differnet kind of permission restrictions), sql express often
failed on attaching database." Does anyone have any opinion on that? Would it be best to change db's to use mssql 2005? How complicated/time consuming will it be to upgrade?Thanks!Jon

Hi, I just started learning ASP.NET this week and have watched a mountain of videos from this website which has helped me alot However I have been stuck on a problem for 2 days now. I have created an SQL database with the Following 2 tables: USERS COMPUTERSUserid Computerid firstname Useridsecondname Manufacturer Model I have made a relationship between the 2 tables. I then created a dataset with the following query:SELECT COMPUTERS.Computer_ID, COMPUTERS.Manufacturer, COMPUTERS.Model, USERS.First_Name, USERS.Last_Name FROM COMPUTERS INNER JOIN USERS ON COMPUTERS.User_ID = USERS.User_ID I however do not get the option in my grid view when i output this data, to UPDATE. The best i have found from google is that i need to use subqueries and not innerjoins but i just cant seem to get my head around them, please help as i feel my head may just explode if i think about this or try any more ways to get this to work :D

Hello
I have a table (part of our fault reporting system) which I now wish to produce statistics from.
I want to be able to display graphs showing how many calls have been registered per day, per week, per month etc.
The key thing here, is that I have a table of calls, one of the fields in there is the dateadded field (the date a call was registered on the system)
I therefore need to get the number of calls logged per day.
I have a feeling this will either involve the use of COUNT, GROUP BY or SELECT DISTINCT (or all of the above) but don't know how to get what I want.
Ideally I will end up with something like the following
10/02/04 10
11/02/04 8
12/02/04 18
With the date as one column, and the number of calls logged that day as another
Thanks in advance for your help

I'm trying to design a database that handles Clients, Cases, Individual and Group Sessions. My problem is that a client can have individual sessions and belong to more than one group at the same time, so I have a many-to-many relationship to deal with. Also I'm trying to design it so that I can have a form that when a group is selected from a drop down it shows all clients assigned to that group and will let me enter new session data for them.
Just looking for some advice on how to handle the relationships.
Maybe someone could show me how they see the relationships working.
My take is that the session is linked to the case not the client, I could be thinking incorrectly?
Thank you,
tblClient
tblClientCase
tblCaseSessionLog

Hi all,
I'm about to embark on a new project and I'm having a few troubles deciding what .NET technologies I need to learn and employ.
The system will be built around SQL Server.
It will involve a client application that will be used to gather data offline using MSDE, then sync back up with the online DB. This will then have a web front-end for users not employing the client app.
I'm pretty fine with the whole front-end and data manipulation thing, but I don't know where to start with the synchronisation.
Could someone please tell me how I should go about getting the systems to communicate? Do I need to use Web Services and do it by XML? Message Queueing? Or are there simpler ways?
Thanks!

I have a web app which is used to do normal insert/update of employee info. Connected to each employee that is entered is some data that is imported from an outside source for each employee. The question I have is currently my database is very normalized and importing data from this outside source will be quite a pain because of this. Is it bad practice to denormalize a specific table if no user will every insert/update it beside DTS?

I'm looking for some advice on the best way to execute a complicated
search on my eCommerce web site. My example here is much simpler than
the real thing, but it should be enough to get the point across.
Imagine that I have two tables:
Products Table
id as Integer
code as VarChar(10)
name as VarChar(50)
mfr as Integer
description as Text
Manufacturers Table
id as Integer
name as VarChar(25)
I need to write a keyword search that will return matches on the
product code, product name, product description or manufacturer name. I
could do a simple join and use a lot of LIKE clauses, but it's not very
efficient.
SELECT p.id
FROM Products p INNER JOIN Manufacturers m
ON p.mfr = m.id
WHERE p.code LIKE '%Keyword%'
OR p.name LIKE '%Keyword%'
OR p.description LIKE '%Keyword%'
OR m.name LIKE '%Keyword%'
Having those wildcards at the start of the like kill performance.
So next I thought, maybe I join all of the fields together, then do the LIKE. For example:
SELECT p.id
FROM Products p INNER JOIN Manufacturers m
ON p.mfr = m.id
WHERE p.code + p.name + p.description + m.name LIKE '%Keyword%'
This is certainly better than above, but it still doesn't seem ideal.
Can anyone suggest something I might not be thinking of? The product
codes tend to have dashes, periods and numbers that preclude the
Full-Text search features of SQL Server, so I'm grasping at straws for
a better approach...
Thanks in advance....

I currently have a web form with about 12 procedures (containing stored
procedures) updating several database tables after form submission. I
will however have to use the transaction mechanism to make sure that
all relevant tables are updated after submission and so avoid data
entry which will have only some of the tables updated and not others.
From my very basic understanding of implementing transactions, I will
have to create a single procedure containing all the stored procedures
which are currently in their own separate procedures. Is that correct?
Thanks!

I need to make a database that only allows users to edit thier own information in a database of many employees. I started out with Access because thats all that I was given but I found that I could only restrict updates to groups of users and not just one employee updating only his own information. Would SQL Server be able to do somthing like that... or can even Access and I just missed somthing?

I know that indexes can hurt perfromance on tables that are constantly being updated. I have a resume database that will have people inserting their info, and also a lot people reading these resumes. There will be more reads and writes, but I think I may get enough writes to slow down performance(because of re-indexing).
What does everyone think? I know I'm not providing a lot of detail, but I am looking for some general comments.

Hello all. I have some questions that are probably pretty stupid but Ill ask anyway :)
It is important that I start down a path of understanding mssql 2000. I wanted some advice from experts as to what the best way to start would be. Is there a great book out there? Can I run a version locally that I can play with? Also, when using the database, are the commands the same for mssql and mysql? I ask because I searched for tutorials and a lot more mysql tutorials popped up.
Obviously I dont expect to become an expert in a few weeks but if I could start down the path I would be happy. Maybe learn how to do simple maintenance and management functions.
Any advice would be greatly appreciated.
