Hi,
What is the best way to have native win32 code tell SQL Server 2005 Express to synchronize for merge replication? What API should I use? Should I exec the distrib.exe and/or replmerg.exe command line utilities? Should I use "Windows Synchronization Manager"? Are they other options?
Thanks,
Bryan
Hello, I have 3 tables with their columns: [Articles] > ArticleId, ArticleText [Categories] > CategoryId, CategoryText [CategoriesInArticles] > ArticleId, CategoryId I created a stored procedure that has the following inputs: ArticleId, ArticleCategories ArticleCategories is of type NVARCHAR(Max) and has categories in CSV format: "Category A, Category B, Category C" I have a function, CSVTable, that creates a table with all the categories. I need to make a kind of synchronization: >
Update all categories for the given ArticleId. If any Category is no
longer associated with any ArticleId (In CategoriesInArticles) then
remove it from table Categories.
I've been searching for a bit but I can't seem to find a difinitive answer.
Can an SQL Server trigger call native C/C++ functions? If so, what is the mechanism?
Thanks in advance.
I'm getting this error while executing a SQLCECommand (ExecuteNonQuery):
Native Code: 25009
Massage: Unspecified error
HResult: 2147467259
Source: SQL Server 2005
Mobile Edition ADO.NET
Data Provider
This happens only sometimes. If I recreate the command object and executing it again (with the same connection object) no error occurs.
Except for this case the application works fine.
Thanks,

Hello, everyone.
I have to make a gateway to access third-party closed-source native-code COM objects. As an interface, SQL Server stored procedures are absolutely perfect for my needs. I decided to use SQL Server 2005 CLR rather than using deprecated extended stored procedures or accessing COM objects directly through SQL Server. (This decision is aided by the fact that the third party has plans to make a .NET version of their COM objects "really soon now" (i.e.: not soon enough). Backporting their new interface to my abstraction layer will be very simple.)
I'm having problems using these COM objects from my SQL Server 2005 CLR stored procedure. When I try to run my stored procedure, I get the error below. It appears that SQL Server/CLR refuses to perform the disk access necessary to load the COM object from disk so that it can instantiate it. (My message continues after the error.)
Msg 6522, Level 16, State 1, Procedure MyStoredProcedure, Line 0
A .NET Framework error occurred during execution of user defined routine or aggregate 'MyStoredProcedure':
System.IO.FileLoadException: LoadFrom(), LoadFile(), Load(byte[]) and LoadModule() have been disabled by the host.
System.IO.FileLoadException:

.
I'll outline the steps I performed so far to get the assembly working:
Ensured I was running at SQL Server 2005 compatibility level. (90)
- Installed and configured the third-party COM objects on my devel box and my DB box. They registered themselves properly.
- Enabled CLR in the DB.
- Made sure the DB owner has UNSAFE ASSEMBLY permission.
- Added the TRUSTWORTHY property to the DB. (Yes, this isn't the "correct" way to do it, but I didn't want to deal with code-signing voodoo. Apologies to actual believers in voodoo.)
- Created an Unsafe assembly "MyAssembly" in SQL Server 2005 and Visual Studio 2005.
- Created all the necessary Interop assemblies (by creating a normal (non-SQL) C# project and building my code, and raiding the bin directory).
- Added these Interop assemblies to SQL Server 2005 as Unsafe assemblies.
- In VS2005, built my SQL Project code and deployed successfully.
- Tried running my stored procedure through a Query window, and I got the error above.
I've done many searches. All of the results I've found concern themselves with Web Services and XML serialization, and suggest using sgen.exe. I don't think they're relevant to my problem. A few said I should add my COM DLLs as assemblies to SQL Server, but that is impossible for native code DLLs. I found something that hinted at tblexp.exe, but I didn't understand how that could help me. I already figured out a way to get me the Interop libs.
Efforts at solving:
- Reading webpages for hours on end.
- I tried using sgen.exe to create the XML serialization assembly, but it didn't help.
- I tried adding various native-code DLLs directly as SQL Server assemblies, but you can bet it didn't like that.
- A few other pitiful attempts not worth mentioning.
- Reading this forum. I didn't see anything that applied.
- Posting here.
I really wish Microsoft had meant what they said when they stated that "Unsafe" assemblies can access anything, instead of trying to protect developers from their folly.
Any insights on getting those COM objects to work in my CLR stored procedure? Thank you.

Howdy folks! (I feel im creating too many topics...but all my questions are unrelated :-/)
Dev environment: SSCE, Native c++ OLE code, Win CE 5
I have a routine that calculates the size of a set of columns in order to create a byte buffer for retrieving data from an IRowset and inserting it into a custom class. This method works great for all data types except ntext. When I look at the column information from an ntext field, the DBCOLUMNINFO::ulColumnSize member holds 536,870,911 (the max length of an ntext type). Obviously I dont want to allocate 1GB of memory for each ntext column. Is there anyway (natively) to determine the actual number of characters in a field?
Hi,
I experienced this problems on both Windows Mobile 2003 SE and Windows Mobile 5.0.
Its native development (c++, oledb, atl and mfc).
It's quite simple to reproduce...
1. open a database
2. open a rowset on table A (whatever, valid of course and with both IOpenRowset and ICommandText), read datas and close rowset
3. power off
4. power on
5. try step 2 with another table (failed on openrowset with error 0x80004005) or try table A (sometimes working because of cached memory, sometims failed on Read Datas).
6. being stuck ;-)
Our work-around was, in case we loose our connection (identified by error 0x80004005 on openrowset), we close it and re-open database... ugly for sure, but working.
What I'm looking now is to use some kind of "detection method" like what people in .Net develoment are using "if ConnectionState.Open <> ...) for reopening my database only on demand...
Thanks in advance for any hints,
Fabien.

I have two customer tables in SQL Server, but some of the field names are not the same, that I need to synchronize. Here is how they are structured: (Table 1 is old and Table 2 is new)
Table 1 (900 records)
---------------
cust_code
cust_shipto_code
cust_shipto_name
cust_email
Table 2 (700)
---------------
custcode
loccode
custname
custemail
1. First I need to find out what records exist in Table 1 but not in Table 2 and add them to Table 2.
2. Secondly, I need to then find all records in Table 1 that match the records in Table 2 and update the Email address in Table 2 with the data from Table 1.
Any suggestions on how to do this sync?
I am tryign to sync two tables that are in two different databases. It is suppuse to update the record in the [orgloc] table if the customer ship to name has changed in the [opcshto] table. The cust_code would be the unique identifier. in both tables.
this is what I have:
UPDATE [r2lprospector].[dbo].[orgloc]
SET [r2lprospector].[dbo].[orgloc].[custshiptoname] =
[cimpro1].[dbo].[OPCSHTO].[cust_shipto_name]
from [cimpro1].[dbo].[OPCSHTO], [r2lprospector].[dbo].[orgloc]
WHERE [cimpro1].[dbo].[OPCSHTO].[cust_code] = [r2lprospector].[dbo].[orgloc].[custcode]
I keep getting an error though. The error is:
Server: Msg 8152, Level 16, State 9, Line 1
String or binary data would be truncated.
The statement has been terminated.
Any help is appreciated.
Hi,
I have a SQL database in my server. One Software is using this database for editing /add / remove items in the database. I would like to put this database in the net (using ASP).
How can I synchronize the SQL database in my server with the same one in remote?
Appreciate your help
Thanks!

Hi,
I am trying to create a type of synchronization but I am having a lot of problems to make this work.
I have 3 tables:
CREATE TABLE Articles (ArticleId INT, ArticleText NVARCHAR(512))
CREATE TABLE Categories (CategoryId INT, CategoryText NVARCHAR(512))
CREATE TABLE CategoriesInCategories (ArticleId INT, CategoryId INT)
Consider the following tables content:
Articles Table
ArticleId ArticleText
1 Game ended 1-1
2 Book Review
Categories Table
CategoryId CategoryText
1 Sports
2 Entertainment
CategoriesInArticles Table
ArticleId CategoryId
1 1
2 2
I need to create the following procedures:
CreateArticle
Create Procedure [CreateArticle]
@ArticleText NVARCHAR(512),
@ArticleCategories NVARCHAR(MAX)
As
Begin
...
End
This procedure should the the following:
1. Create the article in table Articles
2 .Use the function CSVTable that returns a table with all the categories contained in @ArticleCategories.
For each category check if there is already one with the same CategoryText in table Categories.
If there is just get the CategoryId and add a new record into CategoriesInArticles with ArticleId and found CategoryId.
If there isn't any then create the new Category into table Categories and then add the new record to CategoriesInArticles.
DeleteArticle
Create Procedure [DeleteArticle]
@ArticleId INT
As
Begin
...
End
This procedure should the the following:
1. Delete the article in tables Articles and CategoriesInArticles given its ArticleId
2 .Delete categories from table Categories that are no longer associated with any other article (in table CategoriesInArticles)
UpdateArticle
Create Procedure [UpdateArticle]
@ArticleId INT,
@ArticleText NVARCHAR(512),
@ArticleCategories NVARCHAR(MAX)
As
Begin
...
End
This procedure should the the following:
1. Update the values into Articles Table
2 .Use the function CSVTable that returns a table with all the categories contained in @ArticleCategories.
I think the easiest way is to delete all the categories from ArticleId as it is done in DeleteArticle.
Then It creates the new categories as it is done in CreateArticle.
Consider I create a new article:
EXEC CreateArticle @ArticleText = "Book launched at sports event" @ArticleCategories = "Entertainment, Business"
The tables would become:
Articles Table
ArticleId ArticleText
1 Game ended 1-1
2 Book Review
3 Book launched at sports event
Categories Table
CategoryId CategoryText
1 Sports
2 Entertainment
3 Business
CategoriesInArticles Table
ArticleId CategoryId
1 1
2 2
3 2
3 3
NOTE: Because there is no category named Business in Categories this must be created.
Then I would updated it:
EXEC UpdateArticle @ArticleId = "3" @ArticleText = "Book launched at sports event" @ArticleCategories = "Sports, Tech"
The tables would become:
Articles Table
ArticleId ArticleText
1 Game ended 1-1
2 Book Review
3 Book launched at sports event
Categories Table
CategoryId CategoryText
1 Sports
2 Entertainment
4 Tech
CategoriesInArticles Table
ArticleId CategoryId
1 1
2 2
3 1
3 4
Note: Since Business category is no longer used by any other article then it is also deleted from Categories.
The new Tech category is then created and associated with the updated article as well as the existing category Sports.
Finally I would delete it:
EXEC DeleteArticle @ArticleId = "3"
The tables would become:
Articles Table
ArticleId ArticleText
1 Game ended 1-1
2 Book Review
Categories Table
CategoryId CategoryText
1 Sports
2 Entertainment
CategoriesInArticles Table
ArticleId CategoryId
1 1
2 2
Note: Since Tech category is no longer used by any other article then it is also deleted from Categories.
The Sports category is not deleted from Categories since it is used by Article with Id=1
Well, I hope I didn't miss anything and I explained it well.
I have been trying my code, either by creating a separate procedure named SynchronizeCategories or inside the Create, Delete and Update procedure.
Until now I was not able to make this work.
Here is the code I use in my SynchronizeCategories procedure:
INSERT INTO CategoriesInArticles(CategoryId, ArticleId)
SELECT c.CategoryId, @ArticleId
FROM Categories c INNER JOIN CSVTable(@ArticleCategories) ac
ON c.CategoryText = ac.String
LEFT JOIN CategoriesInArticles cia
ON c.CategoryId= cia.CategoryId
WHERE cia.CategoryId IS NULL
INSERT INTO Categories(CategoryId, CategoryText)
SELECT cia.CategoryId, NULL
FROM CategoriesInArticles cia
JOIN [Categories] c ON c.CategoryId = cia.CategoryId
INNER JOIN CSVTable(@ArticleCategories) ac ON ac.String = c.CategoryText
WHERE c.CategoryId IS NULL
DELETE c
FROM Categories c
INNER JOIN CSVTable(@ArticleCategories) ac ON ac.String = c.CategoryText
LEFT JOIN CategoriesInArticles cia ON c.CategoryId = cia.CategoryId
WHERE cia.CategoryId IS NULL
Could someone, please, help me out with this?
Thank You Very Much,
Miguel
Please can somebody help me with the following:
Our company has an enterprize site (a very large one). From time to time we need to make changes in it. In other words, we had to synchronize one database (local where we make all changes) and database on hosting. So, we did it manually (wrote scripts and inserted them in database on hosting). But as the databases grew it became impossible to synchronize everything manually. So we need some tool which could cope with this task. The problem is that, as I know, there are many tools which can do it, but we are tight in time and can't evaluate them all. Please share your ideas on what tool is worth evaluating?
Thanks in advance.
Please we need help in the next Scenario:-
- Head office SQL Server 2000 including main database (huge db for about 8 systems).
- 8-10 branches with small database (for 3 systems only).
- No connection available between all offices.
1- In daily basis we need to transfer all transaction updates done in all offices to update the main database in head office.
2- After updating head office we need to transfer the last case in 2 or 3 tables to all offices again.
3- There are some common tables, managed in head office only (usually not changed), in case this tables changed for enhancement or anything else, we need to transfer this change to all offices.
NOTE: No connection available every where, therefore we need hand carry solutions as soon as possible and please tell me in details as you can because the time is too short.
Using a web interface, I am placing text into a SQL database. From timeto time, I would like to synchronize one of my other tables in thedatabase with the table that I am inserting content into. What is theSQL command to synchronize these tables? I will be initiating thiscommand through a web interface, so I cannot use enterprise manager.Thank you very much!
View 4 Replies View RelatedI want to replicate my database with table like this:+-----------------+
| Table |
+-----------------+
| ID |
| Distributor ID |
| Total Sales |
| ... |
+-----------------+
At table above you can see that I have a field called Distributor ID. The scene like this, I have 4 distributor that have replication of my database. Each day they synchronize database from distributor (lets call they A, B, C, D) into my server. So at the server have data with Distributor ID A, B, C, D. But if an distributor want to download its data from my server, they only have data with their ID, for example distributor A have synchronize their data with me and now want to download the data from me, so I only send data that only contains Distributor ID A, so that A can not see data from other distributor (B, C, D) that rule also applied for B, C, and D.
The summary simple like this, I have all Distributor data (data from A, B, C, D) but each distributor only have their own data if they download from me, A only have A data, B only have B data, so on).
Thank you.
I am new the Replication service.
If I have 2 server A and B. A has a table named "Table1" and B has a table named "Table2". The schema of table is same.
Could I do the replication (E.g. snapshot) from A Table1 to Table2 in B? If yes, how?
Thanks.
Hello,
I have an Access database that updates each 5 minutes with data from a weather station. As you can imagine the access database is becomming huge, so I would like to get that data into SQl Express to make queries faster and better connectivity with visual webdeveloper.
There is no way I can get the data directly into the SQL Express database, as the vendor only supplies a tool for MySQL and access through odbc.
Is there a way to sync the access database and my SQL Express each 5 minutes?
And off course not manual
Thank you...
I am attempting to follow the example from VB.NET 2005 on synchronizing and SQL Database and an SQL Mobile 2005 db.

Hi,
I have a little problem. I need to synchronize data from two tables with different table structures meaning they may or may not have the same column name and/or table name. I have read a lot of midware tools which I can use but is there a way inside sql server where I can do this? And this synchronization should be automated. Like when I update one table, it will automatically update the other table with the data that was changed. I know I can manually update the records but is there an automated way that I can do this? I have also read about integration technologies supported by sql server like ssis and replication but it seems complicated and I dont have the luxury of time to learn these. But if these can be the answer to my questions then I guess I dont have a choice. Please help. Newbie in sql. Thanks!
I made application (using .NET) to transfer data using PDA via GPRS and
then upload data to database server. The data not update old data but make
new insert new data to database server.
If we use USB to synchronize data from PDA to database server, we can use merge
replication. But i still confused how to synchronize data, if we transfer data from
PDA via GPRS, then insert to database server???

Hi,
First post on the site, yippee! So first of all I'm not a DB pro but occasionally need to hire someone, and to do this properly I need to understand the basic workflow.
Could really use some advice on comparing and synchronizing 2 different SQL databases in different geographical locations..... need updates from website A SQL database to be automatically updated to website B in as close to real time as possible. The whole database doesn't need to be transferred every time, only specific information regarding personal profiles and their activity on the other site. The end result would be that users can login to their profiles any time on either website and see up-to-date reports on their activities/results.
I know it would be much easier to host both databases on the same server but for various reasons this is not an option.
The past day was research into all the various SQL DB synch software. Having a hard time finding unbiased viewpoints...
First of all is there any reliable and secure open source alternatives? I searched sourceforge and found 'SQL Server DB Compare and Synchronize', but it doesn't seem to have full automation.
Also found a few paid for solutions through other forums such as 'Red Gate' products but they would cost upward of $3-500
I need something that is secure and reliable, don't mind a bit of customization but would prefer a solution out of the box.
any advice/articles/reading material/recommendations would be greatly appreciated
have a nice day :) Derek
Hi,
I have the following scenario:
There are 3 web applications in a local network which all have a local copy of the same database. Each of them can alter their local database (just the data, not the structure), and every time that happens the databases of the other applications should be updated immediately.
Are there any solutions out there for that? I found that most tools like slony only mirror one master database to multiple slaves, but I want every database to be able to be the starting point.
There could also be a central sync server, like in subversion..

Patrick
Hi,
I have a scenario which I need to implement at my work.
I need to maintain one Central SQL Server DB and multiple non central SQL Server DBs at different locations. Here the same DB schema is maintained at Center & non Central SQL Servers. The requirement is: each non central DB has to synchronize with the central DB and has to update the Central DB with the changes made locally.
Here the challenge is the intermittent connectivity between the DBs. The connection is not guaranteed to be alive 24 hours a day. It may go down frequently also. I would like to know the possible ways to handle my situation (i.e. synchronization). And also please suggest me if there is any support with the SQL Server DB itself.
Thanks,

i have 2 DB in 2 different servers.
db1 and db2
db1 gets 150k records every hour. db2 is like the backup of db1. db2 is used to retrieve records to create reports using reporting services.
what is the best way to synchronize db2 with db1?
is it to create a dts package and set up a job that runs every hour?
off topic question.
what kind of language does reporting services use to create the reports?
i have 2 db's that are totally different except that they both have a table users and I want to make it that anytime the user table is updated or added to in one db - that it is copied over to the other db.
is this possible?

View 7 Replies View RelatedHi,
I have decided to use CLR Triggers to synchronize data between two different tables but I have a problem. The scenario is this. I do an insert in Table1. Table1 firest the trigger which then inserts a record in Table2. The trigger in Table2 fires a trigger which does an insert to Table1 again.
I need to find a way to disable the trigger so that it will not go in an infinite loop when I insert a record in either of the tables. What I have done so far is to disable Table2's trigger before I commit my insert to Table2 so that Table2's trigger won't fie. I will then enable the trigger after the insert is committed. Also, I have a webservice which manages the inserts/updates/deletes. I call webmethods from this webservice in my clr triggers.
Help please!

Hi everyone,
I would like to know if using Service Broker to synchronize another non MS DB with this technologie is suitable?
My idea is to place in messages the modification of any table and then have a windows service or web service to read this Service Broker Messages, and then update another database (Intersystems Caché).
Any other ideas are welcome!

Hi,
I was wondering if the following is possible: I have 2 SQL Express servers on different machines. One holds the production and one the development database. On a request basis I'd like mirror all the data of the production database to the development database. Right now I have to stop the sql engine, zip the mdf, send it over, attach it to database, etc. and that's quite cumbersome. So, is there an easier way to do this? If not with SQL Express, is it possible with the full version?
Thanks,
Tom
Hello:
Next week I have a database going into production and now I need to set up
a separate reporting database. This is no problem except that I'll probably
need to load data daily from production into the reporting database.
My questions:
1) Can I trust the EM transfer manager to refresh the data nightly in the
reporting database? Will it truncate the pre-existing data.
2) Must I be logged into the reporting database(destination) always or
should I incorporate that into a script? How?
3) Has any one experienced any problems using transfer manager for this
purpose?
4) What alternative should I use? bcp?
Thanks.
