Say for example, that I have a fairly complicated record of a thing
meant for the US market. Then, a Canadian version is created based on
the US one with a few changes so I want to track the connection. It is
fairly easy to make a ParentID field that would indicate the Canadian
thing descended from the US thing.
But, if I then make a British thing from the Canadian one (and I want
to do this because the Canadian one is a closer match to what the
British one needs to be), it becomes more complicated... I can put the
ID of the Canadian one in the ParentId field of the British one. But
then I need to run multiple queries to build the complete lineage back
to the original US record.
More so, if I want to allow n-number of levels to the relationships
between these things, it becomes even more difficult.
This type of issue has come up repeatedly in my work, so I assume it
is not a new problem and that there may be a "best practice" for
handling it.
Can anyone offer any advice, an answer, or point me toward a place
where I may find the answer?
I am serving ad-units. In each ad-unit I show somewhere between 3 and 10 article headline. I track the headline impressions to get an idea of the headline click through rate. I save the output from the stats process in another table. I am currently evaluating the stats every hour, and then truncating the table every night at midnight. The problem is that I get lots of impressions and the database gets bogged down evaluating the data such as... SELECT COUNT FROM articleimpressions WHERE articleid = x
But the issue isn't the reporting of the data...so much as it's the capture. I had to add caching on the ad-server because the database couldn't handle the number of inserts.
I thought about parsing the web server log files the next day, but the file sizes seem to be too large, and I can't process them all in one day. (At least not on the hardware that I am using.)
I've thought about splitting log files by hour, but was wondering if there may be a more "native" solution within SQL Server? Maybe a trigger, and/or multi-threaded SP that fires and forgets an insert statement to a linked server. But performance is the key here.
I am running an SSIS package and I keep getting this error when it gets to a the dataflow task. I have a bit of an idea of what it means, but I can't figure out how to fix it. IF anybody could explain this error and fixes for it that would be of immense help. Thank you.
Error: 0xC004701C at Load Server Security, DTS.Pipeline: input column "Server" (1434) has lineage ID 1421 that was not previously used in the Data Flow task. Error: 0xC004706B at Load Server Security, DTS.Pipeline: "component "OLE DB Destination 1" (1420)" failed validation and returned validation status "VS_NEEDSNEWMETADATA". Error: 0xC004700C at Load Server Security, DTS.Pipeline: One or more component failed validation. Error: 0xC0024107 at Load Server Security: There were errors during task validation.
Very often during dev. I add processes that don't change the metadata of a data item (for example a new sort) yet the linieage id is changed. This causes lots of headaches down the pipe. If metadata of a data item is not changed in the pipe, why is the lineage id changed?
If lineage is not smart enough to figure out when some metadata was actually changed, should it be made smart enough? Or optional?
is there any "robust" way to find out the name of a field in the pipeline by it's Lineage ID programatically? There is a sample code out there (on one of the blogs) but it seams not to be reliable...
The usecase is easy... What is the field name in an error output of that column that causes the error? We don't want to have hardcoded LineageIDs in the error handling so I think it's the best idea to go with field names... However we only get that LineageID...

I have developed a SSIS package on my desktop and the package involves loading of XML data into a database. The XML does not have inline schema and I generated the XSD file from SSIS.
I used Derived Column and Data Conversion to load the data into the database.
Now, i want to migrate the package to a server. Now, when i change the path of the XML and XSD files, all the tasks show error such as
"Input column 'Last_Updated' (4433) has lineage id 3586 that was not previously used in data flow...."
Why is this so? I am using the same XML/XSD files after i moved to the server.
I am working on a custom component to implement some rules based on the column name. I am looking for ways to identify the column name using lineage id. Is there anyway we can derive column name using the lineage id?
Okie, this one has me a little stumped so bear with me an I will explain as best I can....
I have a family tree database...
The two key tables (for this problem) are Person and Child. The person table is your generic person details table and contains, PersonId, PersonFirstName, PersonLastName, PersonDOB etc. The Child table is a linking table that links a PersonId to a ChildPersonId (so both Id's are valid Id's in the person table).
Now what I want to try and achieve is a breakdown of the different branchs of the family tree. A branch is an independant, unattached section of the tree (if that makes sense). It's a grouping of people we know are related but we can't determine how they are related to another group of people in the tree.
If you look at this http://gw.geneanet.org/index.php3?b=bengos&lang=en;m=N;v=van+halewyn you will get an idea of what I mean.
I'm not sure if this is something that can be don't with a query at all the be honest... I suspect that I will have to wrap some other code around it, but I'm really not sure on what approach I should be using. Any help people could offer would be great.
When trying to open the Family.MDF file in this program this error is displayed: Database cannot be upgraded because its non-release version (587) is not supported by this version of SQL Server. How can a current version of this file be obtained? Thank you, Tom
I am new to SQL 2005. I have setup and new maintanaince plan of making backup on to different paths but i encountered an error saying Executing the query "BACKUP DATABASE [promis_05] TO DISK = N'E:\ERP Database\ERP Backup\Promis_05', DISK = N'\\backupsrv\ERP Backup\Promis_05' WITH NOFORMAT, INIT, NAME = N'promis_05_backup_20061111181236', SKIP, REWIND, NOUNLOAD, STATS = 10 " failed with the following error: "The volume on device 'E:\ERP Database\ERP Backup\Promis_05' is not part of a multiple family media set. BACKUP WITH FORMAT can be used to form a new media set. BACKUP DATABASE is terminating abnormally.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.
We did not know what to make of this. 1) Is it bcoz i am backing up the database on 2 locations same time.
2) What is BACKUP WITH FORMAT?
3) Why won't it let me add a new file that is not part of the 'family' ?
4) How does it get to be part of the family? Thought and ideas are highly appreciated!
I have a family table and would like to group all related members under the same familyID. This is a replication of existing business data, 14,000 rows. The familyID can be randomly assigned to any group, its sole purpose is to group the names:
declare @tv table (member varchar(255), relatedTo varchar(255)) insert into @tv select 'John', 'Mary'union all select 'Mary', 'Jessica' union all select 'Peter', 'Albert' union all
[Code] ....
I would like my result to look like this:
familyID Name 1 John 1 Mary 1 Jessica 1 Fred 2 Peter 2 Albert 2 Nancy 3 Abby 4 Joe 4 Frank
I am trying to restore a 2005 backup to a 2005 database on another server. This has worked for me before. I have tried to take the backup 5 times now and each time I get the error media family incorrectly formed. Since I have successfully backed up and restored before between these same two databases I do not understand what is wrong now.
I found other questions with this error; however, they were taking a 2000 backup to a 2005 database. I am using a backup of a 2005 database to a 2005 restore.
How do you track changes to objects in SQL Server. For example changes in stored procedure,views and indexes. What system table or column track or indicate changes in text of sp or views. Help appreciated.
We are building an inventory management system complete with BOM. It is important to track what employee is updating what tables. Currently all such tables have a Date field that is updated when a change is made, and an EmployeeID field which records the employee making the change. I am wondering if someone knows of a better way to track this information. Any suggestions?
OK. For DDL, please refer to the classical Northwind ORDERS table,problem/challenge, find the longest duration (start_date andend_date), during which, no orders were placed.FYI, column names by the order of colid per syscolumns:OrderIDCustomerIDEmployeeIDOrderDateRequiredDateShippedDateShipViaFreightShipNameShipAddressShipCityShipRegionShipPostalCodeShipCountryAny idea/approach? TIA.
Hi I'm trying to get CDC going, it works however when i query the LSN using the functions i get no changes. The min and max LSN returns null. SQL agent is running, db is on full recovery model etc.
Yesterday I had problem with that a sp that contained join that the developer had forgotten the where part. The sp join very large tables and sp took more 95% dual itanium processor. How do fastest track this down when it accrues. Find the sp or sql that running and consume this much processor resources. I tried with a lot. Sp_who, sp_who2, activity monitor.
im trying to create a procedure that will insert/update a small table that has an ID, AmtBefore & AmtAfter.
this is just a table that i'd be using to monitor other activity on the database.
i'm really pulling a price + ID every hour and i need to track that somehow and know when the procedure runs if a price is lower than it was the last hour, plus of course keep the ID's straight. does anyone have a good approach to something like this?

I have several transaction tables on which I need to track the changes. That is I need to maitain the history of changes. Only few column values are changed often.
Which is the best way for tracking the changes.
1.Store the whole record after the change ?
Or
2.Store the ColumnName & its respective old & new value ?
Or any other better.
Note : UI part & SP's will take care of the tracking & no plans for triggers.
I have a table in my database and it holds some important information,I want to track the users who are executing DML commands(select,update,delete) on the data in that table. Is there any way do that?If so how could i implement that.can any one help me in this regard? Thanks in advance...
First thank you for all your help thus far. Now I'm stuck again. I've been doing a lot of reading on triggers and logging information into tables but I've been trying to capture how many times someone enters an item into the search box.
So every time somebody types Gumballs into the search box I want to capture it and the name of the person who is currently logged in. Is there away to do this? Maybe this is something that I should be checking in ASP.NET forums?
Hello everyone, I have a fairly unique need :) I am trying todetermine the use/clients for databases in my corporation that I ammaintaining, but that noone seems to know what they are for. Many ofthese databases never seem to have anybody connected to them in thecurrent activity.What I'd like to do is find a way to audit the logins, so everytimesomeone connects to a database it simply logs the clients IP address,what login they used, and maybe what time. I've been searching googlefor this and have found tons of information on auditing the logins,but not the clients, such as by ip. Any help in this regard would beGREATLY appriciated!Joshua
I have a device application that simply needs to upload data to a server. The preferred DB server is Oracle but I've made it work using RDA and SQL Server. The problem I'm having is that it just needs to upload data, whichh I send using the RDA.Push() method. The data arrives just fine, the first time. With every subsequent upload all of the previous data is deleted fromt he server. Apparently RDA is tracking the deletion of the previously uploaded data locally and on the next .Push deleting that data from the server.
My question is: Is it possible to prevent RDA from deleting data on SQL Server? I attempted to delete the rows from the __sysDeletedRows/__sysRowTrack tables but got a "Data is read only" error.
I hoipe someone can point me in the right direction here.
I have an application with the following requirements (using SQL CE 2 alas)
A set of tables on the server that need to be imported to the handheld. Using rda, I need to get the modifications to these tables from the server (add/edit/delete) but the handheld will never update these tables.
A set of tables on the server that need to be imported to the handheld. The handheld needs to add/edit existing records, and it needs to get any changes from the server.
A set of tables on the server where the handheld needs to import a subset of the records. It needs to add (but not edit) new records, upload the new records to the server, and download any changed (add/edit/delete) records to the handheld. What tracking options should I use in these 3 cases?
The problem comes in that I need to have some foreign key relationships in the database on the handheld. Since rda munges the names of primary keys (and indexes), I do not know of a good way to add these foreign key constraints. Any suggestions?
I want to keep track of data change and want to enter the pk such as testkey and timing in different table. is it possible without having to write trigger on the table!!!
I've got a table that has frequent updates to it. I want 100% change tracking on this table though, so we can rollback to any previous version, or just see any changes people make.
Is there a best practice for things like this? Currently, I'm using a trigger on UPDATE to take the previous values and store them in a history table. This keeps track of who changes what, and when. Plus the most recent data is seperate and more performant to access.
I've also heard about putting an 'IsActive' flag on the main table and any changes that are made just get marked as In-Active and a new record gets added.
