Sync Between Two Systems
Mar 18, 2007
I need to syncronize two separate databases. One is SQL Server the other is MySql. I don't have a lot of experience with MSSQL and need a little advice on how best (in terms of speed especially) to gather records that have been added since the last sync and any that have been modified. The table in question has datetime fields for both, the time each record was created (CreatedTime) and the time that the record was last modified (ModifiedTime). Sync will happen daily.
I have worked out a few ways I might do this with DATEADD or DATEDIFF, but my question is, what is the most effecient way? Currently I'm just looking for a way to get inserted and updated records from SQL Server to MySQL. I may have to do a two way sync of some sort later.

I have created a VB 6.0 application that reads data from old db files into the SQL Server 2000 database using DTS stored structure files.
The application works fine with Windows NT but I keep getting an error in Windows 2000 environment.
"-2147220441(80040427) Execution Canceled By User"
Any ideas why?

I was wondering if anyone could suggest a web-based help desk systemthat uses MS SQL server that also has a knowledge base and also allowssupport employees to log how much time they have spent on eachparticular ticket. I'm after an 'affordable' system that would be usedby about 35 people.Otherwise, if you can think of a better place to ask around, let meknow!Regards,Belinda

I have a client that would like to archive all of the documents .word, .xls, .pdf, .jpg, email coorespondance, etc. into some sort of database so in the near future when the project starts up again all of the information is in a clear consise format. I was hoping that this forum could provide some guidance in selecting a software package and a discussion on how to proceed.
I have 6 gigs of documents in a folder on our server.
I was planning on delivering the organized data on a external hard drive after putting the data into some sort of database.
I would like to include metadata about each particular document.
like
who created the document,
Key words about the document's purpose,
time frame the document is revelant for,
and so on.
I would like to use a database structure and possibly hot link the document to the DB.
I would like to use xml (if possible) for the metadata.
any help is greatly appreciated on this
I can be reached at
khively at maximusa dot com
for any additional questions

Hi everyone,
Im having a hard time deciding what approach should I take. The scenario is this: I have developed various systems (inventory, HR, accounting, etc.). All this systems are (and should be) tightly integrated with one another. At present, for all these systems, i've used a single DB prefixing the tables with the systems name (eg. Inventory.Items).
My question is: did I did the right (and practical) thing? Or should I create a DB for each system to organize them? The problem with multiple DBs is some system uses the other system's table(s). Example, if i created a separate DB for accounting, and a separated DB for inventory, and another for HR, how am I going to relate inventory and HR's accounts to the accounting DB's table? I want a single instance for each table; I don't want to create another account table for inventory or HR so I can enforce integrity. And if different DBs, is there a performance impact on this?
Or is there another way? My concern is performance and manageability. Please help. Thanks!

I currently run SQL Server 2005 64-bit Developer Edition (Service Pack 2 - it will be SP 3 as soon as I can get hold of it). I am running this on a stand-alone box with Windows Server 2003 as the OS.
Soon, I will be buying another computer for a colleague who will be running SQL Server as specified above. However, I am not happy with Windows Server and am wondering about changing to either XP 64-bit or Vista 64-bit. The machine will not be networked.
I would welcome advice on this since, in some ways, I would be happy enough to use XP or Vista, and think that 64-bit development is more likely on Vista than on other Windows OS's. However, I am not convinced that SQL Server 2005 works with Vista and, like everyone else, have heard plenty of complaints about Vista.
All advice gratefully received.
Thanks.
Chris

I'm working on an income deferral problem and we are using IRR to end up calculating periodic income.
As an example, I have the following inputs:
Number of periods = 9
Initial Loan = 21.46
Instalment amount =15.30
Future value=0
Guess=0.1 (10%)
Using a compiled function from Visual Studio in SQL Server 2008 we get a result of 70.71656373
Using a Microsoft Access function we get NaN
Using Microsoft Excel we get NaN
Using a web calculator we get 70 (ish, the calculator rounds the numbers)
I know that the numbers are odd, some of our data is dirty so we do expect that. I was expecting the SQL process to kick out an error (therefore converting the result into 0), but it doesn't.

In 2000 there was a server level setting you could change in EM, to allow direct modifications to systems catalogs.

We're planning to migrate our db to new and more disk drives, fasterRAID levels and more dedicated disk usage(e.g. placing the translog ondedicated disks). The db server runs on Win2003.Right now we're thinking about what file system to use on the newdrives. We opt for performance, but expect reliability as well.(Goeswithout saying, IMHO ;-))

I was going over this article , and was intrigued by this statement "If SQL Server 2005 Express is running on Windows XP Home, it is limited to five simultaneous connections. If it is running on Windows 2000 or Windows XP Professional, it is limited to 10 simultaneous connections. However, these are limitations of the operating system and not of SQL Server 2005 Express."
What are simultaneous connections? Is this related to Max worker threads defined as 255 on other editions? How does underlying OS impose how many connections can be done to SQL server. And finally how many simultaneous connections can be done in Windows Server 2003?

Hello,
I am in the process of learning SSIS to step into a business intelligence role in my company, which is a Microsoft CRM/GP VAR. I plan to use SSIS for building data warehouses. However, I'm aware that my company also uses a tool called Scribe to integrate data from non-CRM systems into Microsoft CRM. Can anyone explain to me the difference between SSIS and Scribe? Can SSIS reasonably accomplish what my company now uses Scribe to do? Mostly, Scribe seems to be used for scheduled one- or two-way scheduled data pushes.
Thanks,
Andy

We are currently utilizing a risk management software that is using a SSMS back end. However the database is extremely normalized and hard to find data. I am looking for one particular item (column) to bounce against another report I created, to find the delta's.
I found an XML string that looks to have data captured in it, almost like VB marked up in XML. This XML has the column name (source and the desitination column). However when I go into the other tables I am unable to find either column?
Could it be that the application is referencing the XML strings in the column to present the data through the application? Is this some sort of way to prevent people from back dooring their data? Maybe I just missed the table with the column name.

Hi all,
I am a Windows Sysadmin (Active Directory, infrastructure, etc) with light knowledge of SQL 2005. I can set up the database cluster on a shared storage device, I know how to get the heartbeat, do simple backups, etc.
My question pertains to disaster recovery. Right now, we use a product called DoubleTake to copy our database over and 'assume' the identity of the failed SQL server. There are two problems with this -- cost of the license of DoubleTake, and additionally, is it the best method?
I have read before, that you don't need to be a DBA to set up a DR scenario for SQL. My goal really is to have two databases -- one in our production location, and one in a DR location that is pretty much cold (for licensing issues).
If our production database should go down, then it would fail over to the DR site.
What is involved in doing this, what type of steps are required, do you NEED a DBA to manage this, or can a sysadmin (such as myself) take care of it? Also, is it worth having DoubleTake to do this job, and does it do a better or worse job, are there limitations, etc.
Thank you for any replies you can give, and please keep in mind that I'm far from a DBA .

I am trying to build a query which will be used in an automated report to calculate failure rates of systems based on cases opened through support. Here is where I am stuck. Some systems may have multiple cases opened within the same span of another cases however we would consider this one failure:
System ACase12013-07-11 13:17:09.0002013-07-15 12:05:03.000
System ACase22013-07-12 16:27:50.0002013-07-12 16:29:12.000
System ACase32013-07-12 17:30:32.0002013-07-12 17:40:11.000
System ACase42013-07-12 19:00:24.0002013-07-12 19:04:14.000
System ACase52013-10-01 18:02:23.0002013-10-01 18:11:26.000
Lets say System A generated those 5 cases however Case 2,3 and 4 all happened within the same period as Case 1 so those 4 cases should count as one failure so my end result should be
System ACase12013-07-11 13:17:09.0002013-07-15 12:05:03.000
System ACase52013-10-01 18:02:23.0002013-10-01 18:11:26.000
And that system should show me 2 failures. I was thinking of using a temp table but not sure if that is possible as I am stumped on how to compare the dates to be able to validate if they fall within the range of an older case and whether or not to include them into the new Temp Table.

I have two db instances on different SQL Servers. One is my test db and the other the prod. db. Each has two tables that hold lookUp values for the entire application. I would like to keep these tables in sync. in both dbs. The prod. db would be the master. I was trying to design a trigger to insert, update, or delete the appropriate records in the test db as they were added or deleted from the prod db.
I'm getting too many prefixes errors on the script when trying to reference the table on the test db using four part naming convention.
Any ideas on how to resolve this issue? Do I need to set up a linked server to accomplish this functionality? If so, how do I setup security for a linked server?
Thanks in advance.

I have a SQL 7 backup file that I restored onto a new server. All the objects within the database are not owned by dbo, instead they are owned by a db user. When I tried to login to the db it said that it wasn't a valid user. So I added the login to the system. Now when I login it says it is not a valid db user. I have attempted to sync the id's but don't know how. In 6.5 I could run an ad-hoc query to match the SUID's for the system and the database. In 7.0 I can not because the suid for the db is computed. Any ideas on how to sync the user ID's so that I can login to the server using the target db as my default and can query the table with prefacing the owner(I can get in if I give my login SA privelages but then I have to preface all the objects with the owners name)?
Thanks in advance for any help that you can offer.

hi,
we currently have a web server/db on-site and a similar backup machine across the country. we're using a pretty bad backup strategy. we zip up a backup file, thats done on the main server every night, then ftp over to the back up server then run a restore.
lately ive been having problems with the main server. i would like to have the machines sync'd up as close as possible.
ive searched the threads and noticed replication and log shipping to be the most practical, but im assuming most of the machines are on the same domain.
what would be my best bet for machines connected over the internet, no vpn?
also the db on the main machine get queried/inserts all day from 7am - 6:30pm
thoughts?
thx

how do i write a procedure for the sync between both tables, and put this procedure into the package

How would i write this sync procedure?

Hi all,
I have three tables and i want to bring all tables into sync.
My problem is that the difference in the amount of records is huge.
CORE -- 85659 This table doesnt have a PK
CRF -- 59895 This table has a composite key (MIN,MAX)
DS -- 58595 This table also has a the same composite key (MIN,MAX)
All the tables have their own UIDs. Additionally CRF has a column which stores the UID of CORE table and DS has a column which stores UID of the CRF table.
CORE --> CRF --> DS
UID --> UID,CORE_UID --> UID,CRF_UID
I have only 3 columns (UID, MIN, MAX) that can be used to sync all the tables. Can anybody help me...?
Thanks in advance....
