Looking for a set based solution to the following SQL problem. I've got a solution that uses a while loop but I have a feeling that there is a better way to do this!
I will use a simplified dataset as an example as I don't want to swamp you with too much detail about my real table structures etc...
I have the following tables (plus some sample data) :
insert into dbo.VehicleModel
select 1, 'RT 100', NULL union all
select 2, 'TGB ACKROS TEC', NULL union all
select 3, 'TB 50 PREDATOR 2', NULL union all
select 4, 'TGB 409 CRUISE 50', NULL union all
select 5, 'ESCOR SUPER SONIC 400SL', NULL union all
select 6, 'SUPER SONIC 150 XI', NULL union all
select 7, 'RT X 350 SERIES', NULL union all
select 8, 'TB SALON 4000', NULL
insert into dbo.VehicleModelNorm
select 1, 'ACE' union all
select 2, 'TGB ACKROS' union all
select 3, 'SUPER SONIC' union all
select 4, 'TB 50' union all
select 5, 'RT' union all
select 6, 'TGB' union all
select 7, 'RT' union all
select 8, 'TB SALON'
What I need to do is update the VehicleModelNorm column in VehicleModel with the relevant ID from the VehicleModelNorm table. Sounds easy enough BUT here is the catch. In my vehicles table the VehicleModel are the actual vehicle model names. In my vehicleNorm table I have a more generalized name. What I want to do is look at each VehicleModel, try to find a match in the VehicleModelNorm table, if there is no match then chop off the last word and look again.
For example, starting with 'RT 100 7 SERIES', I want to try to find an exact match for that in my vehicleModelNorm table. If there is no match, remove the last word and look for 'RT 100 7' then look for 'RT 100' etc...
How can I do this in a set based solution? I can do this with a WHILE loop but I have a feeling it might be possible to do this with a CTE but I just can't get my head round it.
Thought I'd got my head round using a set-based approach but my brain's gone dead on this one
CREATE TABLE #mytable (SWID INT , T INT , DateA DATETIME , DateB DATETIME)
INSERT #mytable (swid , t , DateA , DateB)
SELECT 63967 , 1 , CAST('31-Mar-2006' AS DATETIME),CAST( '01-Aug-2006'AS DATETIME) UNION ALL SELECT 63967 , 1 , CAST('31-Mar-2006' AS DATETIME),CAST( '01-Feb-2007'AS DATETIME) UNION ALL SELECT 63967 , 0 , CAST('15-Mar-2006'AS DATETIME) , CAST('01-Aug-2006'AS DATETIME) UNION ALL SELECT 63967 , 0 , CAST('15-Mar-2006'AS DATETIME) , CAST('01-Feb-2007'AS DATETIME) UNION ALL SELECT 63967 , 9999 ,CAST( '28-Feb-2006'AS DATETIME) , CAST('01-Aug-2006'AS DATETIME) UNION ALL SELECT 63967 , 9999 ,CAST( '28-Feb-2006'AS DATETIME) , CAST('01-Feb-2007'AS DATETIME) UNION ALL SELECT 63967 , 9999 , CAST('31-Jan-2006'AS DATETIME) , CAST('01-Aug-2006'AS DATETIME) UNION ALL SELECT 63967 , 9999 ,CAST( '31-Jan-2006'AS DATETIME) , CAST('01-Feb-2007'AS DATETIME) UNION ALL SELECT 10051 , 1 ,CAST('31-Mar-2006'AS DATETIME) , CAST('01-Aug-2006'AS DATETIME) UNION ALL SELECT 10051 , 1 ,CAST( '31-Mar-2006'AS DATETIME) , CAST('01-Feb-2007'AS DATETIME) UNION ALL SELECT 10051 , 0 , CAST('15-Mar-2006' AS DATETIME), CAST('01-Aug-2006'AS DATETIME) UNION ALL SELECT 10051 , 0 , CAST('15-Mar-2006'AS DATETIME) , CAST( '01-Feb-2007'AS DATETIME) UNION ALL SELECT 10051 , 9999 ,CAST( '28-Feb-2006'AS DATETIME) ,CAST( '01-Aug-2006'AS DATETIME) UNION ALL SELECT 10051 , 9999 ,CAST( '28-Feb-2006'AS DATETIME) , CAST('01-Feb-2007'AS DATETIME) UNION ALL SELECT 10051 , 9999 ,CAST( '31-Jan-2006'AS DATETIME) , CAST('01-Aug-2006'AS DATETIME) UNION ALL SELECT 10051 , 9999 ,CAST( '31-Jan-2006'AS DATETIME), CAST('01-Feb-2007'AS DATETIME) UNION ALL SELECT 10051 , 9999 , CAST('31-Dec-2005'AS DATETIME) , CAST('01-Aug-2006'AS DATETIME) UNION ALL SELECT 10051 , 9999 ,CAST( '31-Dec-2005' AS DATETIME), CAST('01-Feb-2007' AS DATETIME) UNION ALL SELECT 10051 , 9999 ,CAST('30-Nov-2005'AS DATETIME) , CAST( '01-Aug-2006' AS DATETIME) UNION ALL SELECT 10051 , 9999 ,CAST( '30-Nov-2005' AS DATETIME), CAST('01-Feb-2007' AS DATETIME) select * from #mytable order by SWID desc, DateA desc
The Columns where T values are 1 and 0 are OK having already been derived. I need to UPDATE the remaining rows from the Default T Value of 9999 to Decrementing values (starting at -1) commencing at the highest remaining (ie non 9999 T Value) DateA value and working 'backwards' 'grouping' on SWID
UCOA is to be updated with the average of all previous transactions where the climstid and isin_id are the same.
example
take case where holdid(transaction no) in the sample data is 14. What i need is a query which will sum up the data in the tran_value column upto holdid 5.
Again I need a set based solution. Gurus .. please help
create table holding ( id1 int, id2 int, datefield datetime, holding int, quantity int ) go
insert into holding select 1,1,'20031210',10,null union select 1,1,'20031211',30,null union select 1,1,'20031212',70,null union select 1,1,'20031213',60,null union select 1,2,'20031210',100,null union select 1,3,'20031210',100,null union select 1,3,'20031210',10,null
go
Quantity is based on Holding for the day - Holding for the previous transaction involving same id1 ,id2.
VB.NET 2005 Express and SQL Server 2005 Express - NOT saving updates to DB - SOLUTION!

The following article is bogus and confusing:
How to: Manage Local Data Files - Setting 'Copy to Output Directory' to 'Do not copy' http://msdn2.microsoft.com/en-us/library/ms246989.aspx
You must manually copy the database file to the output directory AFTER setting 'Copy to Output Directory' to 'Do not copy'.
Do not copy
The file is never copied or overwritten by the project system. Because your application creates a dynamic connection string that points to the database file in the output directory, this setting only works for local database files when you manually copy the file yourself.
You must manually copy the database file to the output directory AFTER setting 'Copy to Output Directory' to 'Do not copy'.
-----------------------------------
The above article is bogus and confusing.
This is rediculous!
This is the most vague and convoluted bunch of nonsince I've ever come accross!
Getting caught out on this issue for the 10th time! And not being able to find an exact step-by-step solution.
--------------------------
I've tried it and it doesn't work for me.
Please don't try what the article eludes to as I'm still sorting out exactly what is supposed to be happening.
If you have a step-by-step procedure that can be reproduced this properly please PM me.
I would like to test its validity then update this exact post as a solution rather than just another dicussion thread.
Many thanks.
This is the exact procedure I have come up with:
NOTE 1: DO NOT allow VB.net to copy the database into its folders/directorys.
NOTE 2: DO NOT hand copy the database to a folder/directory in your project.
Yes, I know its hard not to do it because you want your project nice and tidy. I just simply could NOT get it to work. You should NOT have myData.mdf listed in the Solution Explorer. Ever.
Create a folder for your data following NOTE 2.
Copy your data to that folder. * mine was C:mydatamyData.mdf
Create a NEW project.
Remove any Data Connections. ( no matter what)
Save it.
Data | View Data Sources
Add New Data Source
select NEW CONNECTION ( No Matter what, do it!
Select the database. * again mine was C:mydatamyData.mdf
Answer NO to the question: Would you like to copy the file to your project and modify the connection? - NO ( no matter what - ANSWER NO ! - Absolutely NO ) Then select the tables you want in the DataSet. and Finish.
To Test ----------
From the Solution Explorer | click the table name drop down arrow | select details Now Drag the table name onto the form.
The form is then populated with a Navigation control and matching Labels with corresponding Textboxes for each field in the table.
Save it.
1) Run the app.
Add one database record to the database by pressing the Add(+) icon
Just add some quick junk data that you don't mind getting lost if it doesn't save.
YOU MUST CLICK THE SAVE ICON to save the data you just entered.
Now exit the application.
2) Run the app again.
And verify there is one record already there.
Now add a second database record to the database by pressing the Add (+) icon.
NOW add some quick junk data that you WILL intentionally loose.
*** DO NOT *** press the save icon.
Just Exit the app.
3) Again, Run the app.
Verify that the first record is still there.
Verify that the Second record is NOT there. Its NOT there because you didn't save the data before exiting the app.
Proving that YOU MUST CLICK THE SAVE ICON to save the data you just entered.
Also proving you must add your own code to catch the changes and ask the user to save the data before exitiing or moving to another record.
As a side note, since vb.net uses detached datasets, (a copy/snapshot of the dataset in memory and NOT directly linked to the database) the dataset will reflect all changes made when moving around the detached datasets. YOU MUT REMEMBER TO SUBMIT YOUR CHANGES TO THE DATABASE TO SAVE THEM. Otherwise, they will simply be discarded without notice.
Whewh!
I hope this saves me some time the next time I want to start a new database project.
Oh, and uh, for anyone else reading this post.

I would like to transfer selected data from an ODBC-based table to a OLEDB-based table. However, there isn't a data flow source on the Data Flow Design screen to accomodate such an action. Please help!
Let say I have a table that is composed of 11 columns - one the Primary Key and the other are keys to rows in another table. Of these 10 column 2-10 are nullable. Can I get all the info in one SELECT? I can't use JOINS because columns 1-10 are keys to the same table. I am not very good at explaining these things but hopefully it makes sense.
Hi folks, guidance required! Clients have an MSDE installed and they need all of their data to be dowloaded for the first time from our website. 30 tables r involved. Can i automate this? I suspect BCP allows only one table to be exported into a text file. Since it's the first time process i don't want to setup replication.
Hello All, I have a transaction table that holds nearly a million records and my master with 60000 records,I want to fetch details based on two dates.
I use Union operator to query the info from a view,is this right or fetch the result into a temporary table and fetch the result from temporary table using the same Union operator.
Which is the better way to fetch details faster.

Is there any better/faster select sentance to do this? i'm using sql2000.
Hi, i am not sure if i can solve the problem with SSIS. I wanted do do it hardcoded with C# or so.
So, for my project I need to download zip-files on a daily-base. In these zip-files are xml-Files. And in these files is information stored for inserting or updating tables on a MS-SQL-Server.
So, my question, is it possible to solve that with SSIS? And if, is it easy to understand and to learn within a few days?
I haven't found good sources for information on how to get the data out of XML-Files.
I've got a .dts which load data to several Sql2k servers by Copy SQL Server Objects Task. I'd like to add another task for a Sql25k but I can't because of it's requesting SMO.
It seems that such task need DMO. I know that there are other ways for do such stuff in that DTS but I wonder if there is any trick or shortcut for to avoid this barrier.
I think i have a quite specific problem that we have to resolve with replication. however, i don't know which type of replication to use and how to configure it for this:
To simplify the case a bit: We have one central server which has a table Sales(id, shopid, article). Also our 50 shops have the same table Sales(id, shopid, article).
spec 1: When a shop sells an article, the row of the Sales table at the local shop has to be replicated to the central server. This way, the central server its Sales table has all sold articles from all shops.
spec2: But now we have also an internet shop. All e-orders arrive immediately in the table Sales at the Central Serve with a specific shopid where the article will arrive. Now i have to find a way to replicate the new rows from the Central Server to the specific Shop.... Remark: the other shops should not have rows of other shops.
which type of replication would i use the best and how?

I'm running VS 2005 Enterprise, and SQL Server 2005 Developer / workgroup edition.I'm trying to follow a few online examples to play around, and some of these examples require that you add a SQL DB to your solution by going:-right click on website-Add new Item-Add SQL DataBase.WHen I do that, I get the error that SQL Express isn't installed. Now the question is, why would I want SQL Express installed when I have SQL server 2005 already installed? My Machine can support it, but it's sort of a waste when I need to run SQL Server 2000, SQL Server 2005 and then SQL Server express all at the same time.Any advice?
I'm new in SQL Server 2000. Anyone has a good materials or sites to recommend which talk about Multidimensional Expression? Especially MDX work in "Analysis Manager".
You information are highly appreaciate. Thanking you in advance.
tblClientsCities ID (primary key identity/autonumber) clientID (int) cityID(int)
A client can be located in more than 1 city so i have tblClientsCities (think thats the right way to do it). Say i add a new client and the autonumber changes to "10" which is that client's identifier. How do i then add that identifier to tblClientsCities? I mean it could have been 3,7,205 absolutley anything.
I thought is would be easier to make up a unique key for each client with a script eg
Now that the primary key is known in advance it can be added to tblClients and then tblClientCities. But! i was reading around and many seem to think primary key's like this will slow things down.
So my question is what's the best way of accomplishing this?
What is the best Backup plan that can be give for a sql databse that is on a very high usage. Will a six hour backup will decrease the performance of the SQL server...
Goal:Off-site backup of database without onsite tech intervention
Obstacles: * Webhost does not want SQL Server Agent running for fear of viruses * Database is 3.4GB, LDF is 3.7GB, and a Full Backup is 3.1GB.
Connection / Access:Enterprise Manager, RDP and FTP all work to access data and backups.
I have looked into doing a full backup then differential backups, doing transaction replication, and log shipping. The client doesn't really need replication, he just wants to know that if his server with the production database goes up in flames he has a way of getting back in business without losing more than one day of data.
I am hoping there is a method of "restoring" on his off-site server the data that is "backed up" on the production server. Is that possible if we're doing differential backups?
Is that the best solution or is there a better way?
Thanks for any recommendations or advice, Alec Sherman

I am trying to return a result from a select statement where I want unique (distinct) records but i want to return other columns as well as the distinct column. for example
select distinct field1, field2 from mytable
I want unique records for field1 but for those records returned I also want their field2 value. It seems distinct is not the correct choice for this. I have a hard time imagining there is not a standard solution for this. Can anyone tell me? Thanks in advance!!!!
I have a project named MF_SQL and i have created packages, config files for it, now I need to change the name of the project from MF_SQL to OLF_STG_ACC. So what should i do now to change this. If i change the name what are all the objects affected and what should i do to correct those?
I volunteer for a non-for profit group and they have alot of names in amultiple databases. the problem is that some people are in multipledatabases. and if they send out a mailing from multiple databases somepeople get 2 and 3 of the same thing. my idea was to either make or find aprogram that has everyone is 1 database and then make the people part ofmultiple groups. (ex: bill is part of group a and b and im doing a mailingfrom both group i only want 1 piece of mail to go to him).It can be a separate program or with access. that use access now but i cantfigure out how to make my idea work.any question please ask.tiaStephen
Let me know what you think about the following code:DECLARE @MaxIdValue intDECLARE @MaxSortFieldValue nvarchar(50)SELECT TOP 1 @MaxIdValue = [id], @MaxSortFieldValue = [SortField]FROM (SELECT TOP PageNumber*RowsPerPage [id], [SortField]FROM MyTableWHERE (FilterCondition) ORDER BY [SortField], [id]) TORDER BY [SortField] DESC, [id] DESCSELECT TOP RowsPerPage * FROM MyTableWHERE ([SortField] >= @MaxSortFieldValue) AND (([id] > @MaxIdValue) OR([SortField] <> @MaxSortFieldValue)) AND (FilterCondition)ORDER BY [SortField], [id]This is a dynamic SQL and it should be easily fixable.PageNumber, RowsPerPage, FilterCondition and SortField are going to bethe variables and will be based on the user's searchcondition/criteria.-----------------------------Thanks for you attention.
2- Create/access "local"/"Single-User" files for processing purposes. (try to minimize network trafic...)
So far, I've read a lot about SQL Server products (SQL Server, Sql Server Express, SQL Server CE), at least all articles I could find, and would like to have your opinion on what would be the best approach?
1- What SQL version to use for "multi-user" databases?
2- What SQL version to use for "single-user" databases/files?
3- Can SQL Express allow me to achieve both "multi-user" and "single-user" approaches within same app? If not, what would you rather suggest?
I don't have much background with SSIS or SQLServer or development for that matter. I was thrust in to this and I apologize if my questions are not up to snuff in any way.
I have built an SSIS package based on the import/export wizard and have customized it by adding a For Each Loop container for processing multiple source data files and it works great so far but I need to add some advanced functionality to make it more flexible. I'm having some problems with the best way to enhance the solution and I'm getting frustrated with variables and expressions, which is what I think I need to use. Hopefull what I need is something that's doable.
The package processes mutliple source files using the For Each Loop. The data is stored in a destination table that is dropped and recreated each time. I've also added a couple of CREATE INDEX statements to the source SQL.
I need to make the SQL DROP, CREATE TABLE and INDEX statements dynamic based on part of the filename string. I'm capturing the filename in the FOR EACH container using Variable Mapping. What I need to do is parse out part of the string from the filename and use it in the SQL statements. An example would be CREATE TABLE XXX_[stringvar] where [string] comes from the variable mapping done in the For Each loop.
My thinking was to setup a new variable within the scope of the SSIS package and enable Evaluate as Expression and then build an expression for the varible where I parse out the string from the filename variable that already exists. So if the filename was filename.filetype and I needed the last 4 characters from the filename the string value would be whatever characters were in 'name' each time. But there isn't an expression builder editor built in to the variable properties expression element, so I'm not clear that I can actually create a variable in SSIS and then have it's value be set using an expression. It seems to me that if this was doable, then the expression builder I've seen elsewhere in SSIS would be visable.
Then I was hoping I could edit the SQL behind the DROP and CREATE statements where I've hard coded the table name and insert the variable right in the SQL. My SQL isn't that strong and I don't know how to work with variables but I was thinking the SQL would look like CREATE TABLE XXX_@[stringvar].... I believe another approach would be to setup another string variable for the entire SQL statement and build the statement string dynamically. But I don't know if this is necessary or better.
Anyway, I hope someone can help and that my original post is clear enough.
