Synch
Apr 17, 2006Hello,
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..

Synch-ing Databases
May 13, 2002Hi 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

Keeping 2 DBs In 'synch'
Jan 10, 2005Hi 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!

Any suggestoions are welcome.ThanksTram

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 -
What would be the best solution to update the data from the remote station into the master database???

Merge Replication - How Can I Synch
Sep 8, 2006we 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??
HELP US MICROSOFT: SYNCH BETWEEN SQL EXPRESS AND SQL MOBILE
Mar 28, 2006Hi 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

Sql Server 2005 User Synch
Jan 30, 2008Hi ... 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

Jul 20, 2005Hello,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.

Null Reference Exception During Synch (can't Trap With Try-catch)
Mar 12, 2007Dear 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

Question-Advice Needed: Creating A System To Synch Handheld Entered Data With Main Database.
Jan 30, 2008Greetings!
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!
&"Synch&" Table One SQL Server To Another Via DTS
Jan 18, 2008I was hoping someone could help me with a question. I have a server that has a table with 5.6 million rows of data. I want to use DTS to transfer all the rows in the table from one SQL server to another via DTS, which I have got to work correctly. The problem I'm having is when I run the DTS job the 2nd time, it does all 5.6 million rows again and not just the deltas since the last DTS job. Is there anyway to use DTS to transfer the deltas (ex: 1000 rows since the last DTS job) from server 1 to server 2 ?
Thank you.

Why Would Tables Pulled In From ODBC In Access Be Different Than Tables In SQL 2005 Tables?
Jan 24, 2008I'm new to my company, although not new to SQL 2005 and I found something interesting. I don't have an ERD yet, and so I was asking a co-worker what table some data was in, they told me a table that is NOT in SQL Server 2005's list of tables, views or synonyms.
I thought that was strange, and so I searched over and over again and still I couldn't find it. Then I did a select statement the table that Access thinks exists and SQL Server does not show and to my shock, the select statement pulled in data!
So how did this happen? How can I find the object in SSMS folder listing of tables/views or whatever and what am I overlooking?
Thanks,

Track The Changes To Normalised Tables And Update The Denormalised Tables Depending On The Changes To Normalised Tables
Dec 7, 2006We have 20 -30 normalized tables in our dartabase . Also we have 4tables where we store the calculated data fron those normalised tables.The Reason we have these 4 denormalised tables is when we try to dothe calcultion on the fly, our site becomes very slow. So We haveprecalculated and stored it in 4 tables.The Process we use to do the precalcultion, will get do thecalculation and and store it in a temp table. It will compare the thetemp with denormalised tables and insert new rows , delte the old oneans update if any changes.This process take about 20 mins - 60mins. Ittakes long time because in this process we first do the calculationregardless of changes and then do a compare to see what are changed andremove if any rows are deleted, and insert new rowsand update thechanges.Now we like to capture the rows/columns changed in the normalisedtables and do only those chages to the denormalised table , which weare hoping will reduce the processing time by atleast 50%WE have upgraded to SQL SERVER 2005.So We like to use the newtechnology for this process.I have to design the a model to capture the changes and updated onlythose changes.I have the list of normalised tables and te columns which will affectthe end results.I thought of using Triggers or OUTPUT clause to capture the changes.Please help me with the any ideas how to design the new process

Can I Export Tables So That Existing Tables In Destination Database Will Be Modified?
Jul 20, 2005I'm working on an ASP.Net project where I want to test code on a localmachine using a local database as a back-end, and then export it tothe production machine where it uses the hosting provider's SQL Serverdatabase on the back-end. Is there a way to export tables from oneSQL Server database to another in such a way that if a table alreadyexists in the destination database, it will be updated to reflect thechanges to the local table, without existing data in the destinationtable being lost? e.g. suppose I change some tables in my localdatabase by adding new fields. Can I "export" these changes to thedestination database so that the new fields will be added to thedestination tables (and filled in with default values), without losingdata in the destination tables?If I run the DTS Import/Export Wizard that comes with SQL Server andchoose "Copy table(s) and view(s) from the source database" and choosethe tables I want to copy, there is apparently no option *not* to copythe data, and since I don't want to copy the data, that choice doesn'twork. If instead of "Copy table(s) and view(s) from the sourcedatabase", I choose "Copy objects and data between SQL Serverdatabases", then on the following options I can uncheck the "CopyData" box to prevent data being copied. But for the "CreateDestination Objects" choices, I have to uncheck "Drop destinationobjects first" since I don't want to lose the existing data. But whenI uncheck that and try to do the copy, I get collisions between theproperties of the local table and the existing destination table,e.g.:"Table 'wbuser' already has a primary key defined on it."Is there no way to do what I want using the DTS Import/Export Wizard?Can it be done some other way?-Bennett

Oct 17, 2006I have a trade data tables (about 10) and I need to retrieve information based on input parameters. Each table has about 3-4 million rows.
The table has columns like Commodity, Unit, Quantity, Value, Month, Country
A typical query I use to select data is "Select top 10 commodity , sum(value), sum(quantity) , column4, column5, column6 from table where month=xx and country=xxxx"
The column4 = (column2)/(total sum of value) and column 5=(column3)/(total sum of quantity). Column6=column5/column4.
It takes about 3-4 minutes for the query to complete and its a lot of time specially since I need to pull this information from a webpage.
I wanted to know if there is an alternate way to pull the data from server ?
I mean can I write a script that creates tables for all the input combinations i.e month x country (12x228) and save them in table (subtable-table) with a naming convention so from the web I can just pull the table with input parameters mapped to name convention and not running any runtime queries on database ??
OR
Can I write a script that creates a html files for each table for all input combinations save them ?
OR
Is there exists any other solution ?

Insert Records From Foxpro Tables To SQL Server Tables
Apr 22, 2004Hi,
Currently, I'm using the following steps to migrate millions of records from Foxpro tables to SQL Server tables:
1. Transfer Foxpro records to .dat files and then bcp to SQL Server tables in a dummy database. All the SQL tables have the same columns as the Foxpro tables.
2. Manipulate the data in the SQL tables of the dummy database and save the manipulated data into the SQL tables of the real database where the tables may have different structure from the corresponding Foxpro tables.
I only know the following ways to import Foxpro data into SQL Server:
#1. Transfer Foxpro records to .dat files and then bcp to SQL Server tables
#2. Transfer Foxpro records to .dat files and then Bulk Insert to SQL Server tables
#3. DTS Foxpro records directly to SQL Server tables
I'm thinking whether the following choices will be better than the current way:
1st choice: Change step 1 to use #2 instead of #1
2nd choice: Change step 1 to use #3 instead of #1
3rd choice: Use #3 plus manipulating in DTS to replace step 1 and step 2
Thank you for any suggestion.

Dynamic Tables Names And Temporary Tables Options
Oct 5, 2007Firstly I consider myself quite an experienced SQL Server user, andamnow using SQL Server 2005 Express for the main backend of mysoftware.My problem is thus: The boss needs to run reports; I have designedthese reports as SQL procedures, to be executed through an ASPapplication. Basic, and even medium sized (10,000+ records) reportingrun at an acceptable speed, but for anything larger, IIS timeouts andquery timeouts often cause problems.I subsequently came up with the idea that I could reduce processingtimes by up to two-thirds by writing information from eachcalculationstage to a number of tables as the reporting procedure runs..ie. stage 1, write to table xxx1,stage 2 reads table xxx1 and writes to table xxx2,stage 3 reads table xxx2 and writes to table xxx3,etc, etc, etcprocedure read final table, and outputs information.This works wonderfully, EXCEPT that two people can't run the samereport at the same time, because as one procedure creates and writesto table xxx2, the other procedure tries to drop the table, or read atable that has already been dropped....Does anyone have any suggestions about how to get around thisproblem?I have thought about generating the table names dynamically using'sp_execute', but the statement I need to run is far too long(apparently there is a maximum length you can pass to it), and evenbreaking it down into sub-procedures is soooooooooooooooo timeconsuming and inefficient having to format statements as strings(replacing quotes and so on)How can I use multiple tables, or indeed process HUGE procedures,withdynamic table names, or temporary tables?All answers/suggestions/questions gratefully received.Thanks

Aug 12, 2006Hello all,
Being still a relative newcomer to SQL Server (people may say I'm trying to take on too much being somewhat inexperienced once they read about the problem I'm trying to tackle, but alas...) I'm running into the following problem: I need to create tables in my user database on the fly (using Stored Procedures) so that each table can be created many times in the database but only once for every user. The tables should be named something like "username.Table1", "username.Table2" etc. as opposed to "dbo.Table1". I then want to use the stored procedure from .NET/C# in my web application, so that i can create the complete set of usertables for each of my clients.
Now, I tackled the stored procedure part (that is, it creates all the tables I need with all the parameters I want) and am able to use it from my web application (which took some time to learn but proved quite easy to do), but I cannot seem to get it coupled to the current user (instead of the dbo). Every time I trie, the tables are created as dbo.Table1 and when I try to create a new set, it gives a warning ("table with name such and so already exists..."). I made sure to log in as an authenticated user (using forms authentication) before trying to create the tables but this gives the aforementioned result.
What am I doing wrong? I use Visual Web Developer Express, SQL Server 2005 Express and IIS version 5.1
Please help :-D

At the moment I have one big database that has column titles such as author, book title, rating, isbn, publisher, publish date, copyright date, graphical image review, availability, genre.
I want to break this large table down into say four smaller relational tables. Partly because it is so large and partly to make it easier to bind the data to the web site. I also want to keep the large table.
How can i do this? I use sql server management express. The database is on my hosts database. I also use VWD 2005 express edition.

Dec 19, 2003Ok say I would like to build a table for of the following questions(say 6 questions for the sake of argument):
Do I just stored the index of the radiobuttonlist. What are some resources that I could look at. Should I make a look up table.
5) If money were no object, I would live . . .
Prefer not to say
On a tropical island
In a New York penthouse
In an English castle
On a Texas ranch
In a Malibu beach house
In a mountain retreat (Selected)
On the moon
None of the above

How should I create the database table for the above example.
Joining Tables - But Data Not Always In All Tables
Aug 18, 2007I have created 3 views, which I then want to join to produce an overall result. The first view returns customer details, along with payment information. The next two views return values only when the customer has purchased extras outside our standard product i.e. if there is no purchase of an extra, then nothing is written to the extra's table. When I join the views together they only return values where data has been matched in all 3 views i.e. extra's have been purchased. Any data that did not match in all 3 view (i.e. no extra's purchased) is either ignored or dropped from the results. So I need my script to return all values even if no data exists in the two extra views.
My scripts are as follows:
Main View
SELECT
CUSTOMER_POLICY_DETAILS.POLICY_DETAILS_ID,
CUSTOMER_POLICY_DETAILS.HISTORY_ID,
CUSTOMER_POLICY_DETAILS.AUTHORISATIONUSER,
CUSTOMER_POLICY_DETAILS.AUTHORISATIONDATE,

ELSE 0
END), 0) AS TotalPayable,

WHEN 'NET' THEN ACCOUNTS_TRAN_BREAKDOWN.AMOUNT

I have included all the scripts I have used, as others may find them useful, in addition to anyone that is able to provide me with some assistance. Thanks in advance for for the help.
Reference Tables Or Lookup Tables
Aug 22, 2007I have facing a design problem and unable to justify which design to choose for my data model.
Usually, what we have is like data tables and reference tables to store data in those data tables.
My database has tables with 20-30 columns in them. And most of them (though not all of them), stores data from some reference tables. Meaning each column has an associated reference table where it stores possible list of values for that particular column. Sort of data domain for that column. FYI, My database is related to medical field.
For example, A table that has a varchar(40) column called "Differentiation". It can only store values from following list:
- Undifferentiated
- Moderate
- Poor
- Poor - Moderate
- Moderate - well
Now, to implement this, simple solution would be to have a reference table where I can store all these possible values...And then have just a reference of each data item into my "Differentiation" column in the table.
This is simplest and probably the best solution for such thing and i can also have referential integrity implemented for this.
But now if we look at the bigger picture, my database is growing and I have about 80 tables which I need to create where most of the columns will have different reference tables like I mentioned above. Approximate number of reference tables is 300 tables. All the reference table will have same structure, with different values for different columns.
Now, what seems to me is, because the table structure is same for every column, rather than having 300 different tables, I can only have 2 tables, where I can put all these reference values into these 2 tables.
Like,
Table 1 :
This table can have name of the reference table like "differentiationlist" etc.
Table 2:
It has reference to the reference table list in Table 1 discussed above and all the values that are part of that reference table can go in this table with its reference.
But problem with this is, because all the reference tables are in these two tables, I don't know how to implement referential integrity in this design.
Does anyone have any idea or solution for situation like this?
Thanks,

How To Basically Copy Tables With New Names Rather Than Create Similar Tables From Similar Manual Input.
May 26, 2007I have a table that I am basically reduplicating a couple of times for each part of this database that I want to create.Each table basically has the same data: The tables will be called motherTable, fatherTable, sonTable, daughterTable and so on.I am pretty much using the following in each column: UserID, MotherID(or FatherID or SonID, etc., etc. and so on for each unique table), FirstName, LastName, MiddleName, BirthPlace, Photo, Age.I don't see an option to copy a table and just modify the second ID part and rename that table accordingly.How can I make this an easier way of creating these similar tables without retyping all these columns over and over again?Thanks in advance.
