Hi all, here are my goals: Have the same DB on two different stand-alone computers, and keep them up-to-date from each other.
Basically a user would input to a DB for a week. Then every week or two, update the other stand alone DB with the new input. The DB would be exactly the same.
What are my options for this? I'd like it as easy as possible! Are there any software packages that deal with this type of transfer, etc.? Thank you!
Hello,
I would like to request you to kindly point me to a location where I may obtain more ideas/suggetions/details on how synchronization may be performed in a real world scenario ?
MS has been promoting smart clients and offline availability, but I cant seem to find any material that outlines some ideas/techniques/pointers as to how this may be acheived sans SQL Server replication
Essentially, what I'm looking for is someting that would guide a not-so-solid-with-databases person like me through how synchronization (sans sql replication engine) may be implemented - any watchouts etc..

Hi all,
Heres the deal -
I have several remote users - all running the same program, with a local copy of MSDE...
I would like to setup a master server at my office that will act as a repository for the data that is generated at the remote sites.
I would like the remote users to establish a connection with the server (tcp/ip) and upload all the data they have entered into the local database.
They do not need to download any data - this is accomplished through the web services of SQLXML -
they just need to upload all the data they have, without destroying the data from before.
I have some concerns on the auto-inc that is used in the tables now and how they will react to each other in the master database...
thanks for any help
take care
tony
I have to schedule the automatic restore the standby database fortesting backups . The database was already in log shipping mode. Up towhat point do I need to restore the database without affecting the logshipping sequence? Can we query the log shipping tables for the lastscn applied and recover up to that point? Any suggestoions are welcome.ThanksTram

Hi all,
We are going to have several dozen servers around the country- each with a mirror copy of the initial database (blank) loaded upon them.
The data will be entered at each station, and then once a month, the systems will dial into the 'net and -
this is where i am getting stuck -
we would like the data from the remote areas to update the data in the master database -

we have a merg replication running in three regions UK,USA and AU
my question is in one of our test environment testers managed to get a few tables out of synch while the replication is out.
we have re-established the replication since then and it worked fine untill they try to update records from those out of synch tables. as usual we get conflicts.
we don't really know how many tables are out of synch either. we have about 500 tables.
is there a way to synch tables from with in the merge replication??
Hi Everyone
As most of you do, I am eagerly awaiting the ability to synchronize my sql mobile database on the hand held to a local sql express database on my local machine
I know users in Microsoft have pointed out to us that we are getting things for free.
At the same time, Microsoft is getting our patience for free and at a cost to us developers.
Its nearly April and as one article says Microsoft will release a fix for this inadequacy
Microsoft...we are happy to pay for this. Palm offers it so what is the big deal. Its not the
reinvention of the wheel. We would have liked that instead of the server synchronization
that bypasses the local sql express database
I as many others are happy to pay
Please let us know when you will be addressing this problem.
I would appreciate the feedback and frustration of other developers. Maybe this will show them we are really running out of time with our clients

Hi ... I am converting SqlServer 2000 databases to SqlServer 2005. It is working great for the most part.
The issue I am having is that a user with a schema that owns objects is established in the database and no user is defined in the instance logins. I can see where if I add the instance login then the Principal_id does not match. Cannot drop the user/schema as there are referenced objects.
I got around this in SqlServer 2000 by updating the IDs to match but now they are views and updating is not allowed.
Is there a straightforward way to resynch the database user to a newly created login?
Thanks,
John

View 1 Replies View RelatedHello,I'm relatively new to the database world so please forgive me inadvance for my ignorance. I have recently been tasked at my job withfinding a tool that will perform the following tasks: 1) extractschemas from a db, 2) produce a difference report between schemas fromtwo databases, and 3) synchronize two schemas. The purpose is forproduct upgrades during which an existing database schema will need tobe synchronized with a baseline schema.The tool must support the following database vendors (versions givenin parenthesis): Oracle (8i/9i), Sybase (12.x), Informix (9.x), MSS2000, and IBM DB2 (7/8).I have spent the last several days downloading and researching avariety of tools such as Aqua Data Studio, DbVisualizer, DBExplorer,DBDiff, and AdeptSQL. I thought it would be a good idea to post amessage to a few database newsgroups and ask for any recommendationsdatabase developers may have.So if anyone has any recommendations on such a tool or softwarepackage, I would greatly appreciate any information.Thanks!Chad Smith

Dear all,
I am running into a null reference exception on replication with SQL Server 2005 Compact Edition. The problem occurs at repl.synchronize(). Even though the statement is inside a try-catch block, the exception is not caught, and the application quits.
Device O/S: Windows Mobile 5.0 v 5.1.195 Build 14957.2.3.1
Hardware: Dell Axim X51v, Intel PXA270
Database: SQL 2005 SP2 (no post SP2-patches)
Exception shows as "an unexpected error has occured in AppName.exe. Select Quit and then restart this program, or select Details for more information." Details:
.. at NullReferenceException at AppName.Form1.Synch()
.. at .... (various lines)
.. at AppName.Form1.Main()
The application is based on the tutorial (Creating a Mobile Application with SQL Server Compact Edition) at http://msdn2.microsoft.com/en-us/library/ms171908.aspx.
The application was successfully working initially but then stopped working on replication after some minor modifications which were not related to the replication code, e.g. adding some buttons to the form.
Three things are puzzling me here..
1. The fact that this is a NullReferenceException and not a SqlCeException
2. Why the try-catch block doesn't work
3. Why the exception occurs
Is this a bug or am I doing something wrong here?
Any help would be appreciated.
Code sample below:
Sub Synch()
Try
LogMsg("Deleting db...")
DeleteDB()
LogMsg("Initializing repl...")
Dim repl As New SqlCeReplication
repl.InternetUrl = http://192.168.0.100/SQLMobile/sqlcesa30.dll
repl.Publisher = "TRKSRV"
repl.PublisherDatabase = "trk_db"
repl.PublisherSecurityMode = SecurityType.NTAuthentication
repl.Publication = "Trk"
repl.Subscriber = "Trk"
repl.SubscriberConnectionString = "Data Source=""Program FilesTrk2007DefectTrk.sdf"";Max Database Size=128;Default Lock Escalation =100;"
LogMsg("Adding subscription...")
repl.AddSubscription(AddOption.CreateDatabase)
LogMsg("Synch...")
repl.Synchronize()
LogMsg("Cleanup...")
repl = Nothing
Catch err As SqlCeException
MessageBox.Show(err.ToString & " " & err.HResult & " " & err.NativeError & " " & err.Message & " " & err.InnerException.ToString)
Catch err2 As Exception
MessageBox.Show(err2.ToString & " " & err2.Message.ToString & " " & err2.InnerException.ToString)

Greetings!
I would like to create a database for keeping track of payroll data for employees where the supervisors (job coaches) on our workshop floor can use a Pocket PC device to record the hourly employee data on the fly. Then at the end of the day, the supervisor can place the device in a cradle of some sort and synch the newly entered data into the main database.
I'm guessing that SQL Server Compact edition would be perfect for this type of task? Is that correct? Can someone give me recommendations on how to go about setting this up? What should I use as the main database? SQL Server? Access? Any advice is appreciated!

How do I keep th job history of a job, say if I re-create the job?
We recreate the jobs often as part of a code move, but I'd like to retain the history of the previous jobs?

Hello
my table :
Report :
R_id (PK)
RName
RDate
i am having a few 10.0000 lines and i want to keep the last 10 (or less if not in the table) rows maximum for each name
i can have 100 report by name (100 rows with the same name and of course R_id and RDate are different)
how can i do it ?
thanks a lot for helping
Hi, I have the following code in a query:
SELECT [Issue date],DATEDIFF("dd",[Issue date],[Start date])/365 AS runningdays
FROM Database1..[Insurance Policies Working DB]
WHERE [Policy Number] LIKE '%1368529%'
The part 'DATEDIFF("dd",[Issue date],[Start date])' comes out as 364 if calculated on its own. However, then when it is divided by 365 it comes out as 0. How do I get it to show as a decimal instead of just rounding it down automatically? (Hope I've made sense)
Thanks in advance
we have a simple table
Key, Name, Address, City, State, Zip ................ect
I would like to keep this table sorted by Name, theirfore I won't have to sort my results with every querry.
I think I need to add something to my insert to tell my table - "Hay take Jones", open up the prober place and stick him in the proper spot.
Ex: We have Appleby and Robertson in our table now. My insert would tell SQL Server to take Jones, figure our where he belongs (alpha), and stick him in, resulting in.
Appleby
Jones
Robertson
This way I wont have to as the querry to sort stuff every time I reference this table, this will save lots and lots of overhead. and help keep my clients happy with quick(er) response.
thanks in advance -arthur
Hi
We need to keep track of all changes that are made to our tables.
The changes will be saved in a table that records:
- the table in which the change was made
- the name of the field that was changed
- the old data for the field
- the new data for the field etc..
I've seen a few examples that record the name of the table that was
modified but none that record done to the field level.
Can anybody give some guidance?
Thanks..

I need to update a row but keep a lock on the table (so no one else can update it) while I do run some more code. In Oracle, it always locks whatever you update until you hit commit, but sql server works opposite. How do I tell it not to commit a statement, or how would I explicitly get a lock and then release it later?

Hello everyone,
I have a winform application with C# front end and sql express 05 backend.
In this database i have a table that holds manufacturer provided pricing and the manufacturers we work with update pricing constantly.
We have one table called "manufacturerpricing" which we are constantly inserting and deleting pricing records to/from to keep manufacturer pricing up to date. We may insert and delete as many as 2,000,000 records per month into this table.
This works perfectly fine and we have no problems here at all.
But with that being said, I am worried about the size of the database growing out of control due to temporary space etc. The database just keeps getting bigger and bigger.
How do I run some maintenance to keep the database size under control.
I would like to run this automatically from the C# front end so if ther is a stored proc I can call or an C# assembly I can reference that would be ideal.
Any help is greatly appreciated.
Hi,
I'd like to keep state between calls to a UDF (mainly for caching purposes). I can shove an object into the appdomain using SetData and read it using GetData, but that requires the assembly to be set to UNSAFE. I'm confident I can secure the DB and the assembly fairly well, but I like defense in depth, and if there's another way to save state between calls to a UDF, I would prefer those.
Is there another way to store state between calls to a UDF, without putting data into DB tables or using things that will require the assembly to have such a wide permission set?
Thanks,
Alex
Let's say I develop a 'version 1' of a program/database and ship it to some customers.
Then I continue work on version 2 with some databasechanges etc.
When version 2 is shipped to the customers, they need a way to upgrade their database
from version 1 to version 2. I guess this is easiest done with one/several sql-scripts.
What I want is your opinion about the best way to keep track of the changes between
version 1 and 2. Here are two ways with pros and cons I've thought of:
1 - Keep manual track of every change (index, changed columns, relations etc) and update a scriptfile with all changes.
Pros: Full control of what is happening
Cons: Pretty much extra work and risk of missing some changes.
2 - When version 2 is ready, run some third party tool to get a diff between the databases
Pros: Fast and easy
Cons: The DB-changes may need to be applied in a special order, with default values, etc etc and I'm not sure all tools handle this in a good way...?
So... what is your recomendations? I'm sure this must be a headace in every development project?

This may be more of a data design question and not an ssis question, but figured folks here could have a good idea.....the organization I'm in has the business need of collecting data from outside organizations and tracking what data is bad and what data is good. When I say bad data I mean everything from things outside of range to absolute *** - characters in integer columns, integers in character columns, special characters, etc. The data comes in in the form of flat file so it's a free for all until it hits ssis & the db engine.
Eventually of course they work to get the data corrected at the source & resubmitted but in the meantime, they have the legitimate need of not only pushing the data into the database (dirty or not), but keeping all the bad stuff. I can't in good conscience make everything a varchar to catch everything - that would go against the database gods. IMO - I still must make an integer be an integer , characters are characters, etc. But what do I do with the junk? Any thoughts?
I am newish to databases and would appreciate some
advise. I think I have a solution to my
problem but it is going to take me a lot of time to get it running. If there is a better way of doing it I would
like to know.
I have a table :-
“eventDates� with
columns (id, date, eventID,
eventCount)
The id auto increments as a Primary Key.
date holds the date of the
event.
EventID references another
table with info about the events
Up to 9 eventIDs can be added
for each date and I want eventCount to hold an integer (1 to 9) to allow me to “pivot�
the data to the table below
“results� with columns (date,
eventCount1, eventCount2 …..eventCount9) so each row will hold a date and non
to nine eventIDs occurring on that date.
Is there an easy way to keep eventCount accurate or do I
just have to write a lot of code? I
will need to be able to remove events as well as add them. I will use a mixture of stored procedures
and VB.Net I guess?
Many thanks for any advice.

Hi, I am trying to find a way to capture all the status (Start time, execution time, Status messages etc) from executing a DTS package in to a table I will create in a database, does anyone know, where those information being kept?
When I excute the DTS package manually, a window will come up and show the status of each step within the DTS package. I am hoping to capture these information and load it to my log table.
Thanks in advance.
How can I instruct SQL Server to keep entire table in memory? ie the memory pages should not be swapped to HD.
View 2 Replies View RelatedI'm exporting a large database. In enterprise manager the settings on

I have a trigger that keeps track of status changes...
IF UPDATE(STATUS)
BEGIN
DECLARE @currentdate datetime
DECLARE @currentstatus integer
DECLARE @UserID integer
DECLARE @PermitID integer

It works but not the way I want it to. The @currentstatus and @newstatus are the same. I want the status before and after the update. I asked around as to how to do this and some one told me to use the Deleted table.

I have a stored procedures with few DML stmts inside.
I need to log the success/failure of each DML statment into seperate audit table as follows
Begin

when any of the above DML stmt fails, the entire transaction is getting rolled back including the audit information.
How can i keep the audit info intact when the transaction is rolled back.
