SQL CE Top/limit, Unable To Find WORKABLE Solution
Feb 20, 2007
Hi all, I'm being driven to distraction by my inability to find a workable solution here, i'll try and lay out my problem as simple as possible:
My application analyses sentence structure, it stores hundreds of thousands of web pages, and stores all the words on those pages sequentially in a database with a primary id, the id of the page the word is from, and the word itself of course.
ie : id , parent_id , word
What i'm trying to do (which already works successfully in both SQL and MySQL) is to retrieve the word immediately before the one I specify and 3 words after the word I specify. Ideally in one union query but i'll accept it if that's too complex and go for two for now.
Because of the sheer size of the database ( millions of keywords ) I can't afford to retrieve every single record and feed off the top results in the application itself.
I've attempted to use subqueries:
SELECT yek FROM child_barrels A WHERE 3 > (SELECT COUNT(*) FROM child_barrels B WHERE A.yek < B.yek) AND id>'" + id + "' AND parent_id='" + parent_id[x] + "' ORDER BY id ASC
SELECT yek FROM child_barrels A WHERE 1 < (SELECT COUNT(*) FROM child_barrels B WHERE A.yek < B.yek) AND id>'" + id + "' AND parent_id='" + parent_id[x] + "' ORDER BY id ASC
These raise an error on the first select statement in the sub query.
(SELECT yek FROM child_barrels WHERE id>'" + id + "' AND parent_id='" + parent_id[x] + "' ORDER BY id ASC LIMIT 3) UNION (SELECT yek FROM child_barrels WHERE id<'" + id + "' AND parent_id='" + parent_id[x] + "' ORDER BY id DESC LIMIT 1)
Above directly is the original MySQL code.
I would appreciate any help available on this, thanks in advance.
I have created a solution which contains only 2 packages say Package1.dtsx and Pakage2.dtsx. I want to create a deployment utility to deploy onto other developers machince. I changed the project properties "CreateDeploymentUtility" to TRUE. When I do the build it is not creating the files in "Deployment" folder. It is saying Rebuild All Failed but the error is not showing.
For more information the 2 packages have 4 indirect configurations from environment variables which are storing the actual config file path.
Hi,I want to know the optimal solution, to find if all the data was entered. Lets say, Table A (date field) and for a given month, i need that all the days in the given month are present in the Table A. Right now i have different solutions, 1) a stored procedure which loops through all the days in the given month against a select statement on Table A2) a stored procedure, create a temp table which contains all the dates in the given month, and a single select statement using where condition (select * from.... where datefield not in (select * from...))I want to know what is the best solution of these two or any other solution.Thanks
I have searched the archives and haven't found a solution that works.
I started out with a package based on the Excel import wizard and have modified it to include a for each loop for processing more than one Excel source file and also modified it to do some dynamic SQL like dropping and creating the tables with names that are variable based. The package is cabable of processing more than one file, and each file has the same data elements or columns in it, but each file has to go in it's own table. The drop and preperation tasks use string variable SQL that does dynamically create the SQL and runs great. The data flow task and it's OLE destination task (which the wizard did intially create) does not perform as expected. There were some posts in the archives stating that for dynamic destination table names it can be done in the OLE destination but I can't get it to work. I tried using an access mode of table/view name variable and select a variable that is string expression based. But this variable isn't fully populated until run time and so when I'm trying to configure this I get a msg stating the table name object doesn't exist and I can't save the task.
Am I doing something wrong, or trying to do something that wrong way or trying to do something that isn't possible?
Hello, I'm trying to access the MSSQl 'remotey'. I open telnet and go to 127.0.0.1 1433 but can't. It seems I have done everything I can to fix it, but nothing solves the problem.
My firewall is disabled.
I have TCP/IP enabled in "SQL Server Configuration Manager" for both Client Protocol and protocols for MSSSQLSERVER (Shared Memory and NAmed Pipes are also both enabled). VIA is disabled.
In SQL Services, SQL Server Integration Services, Full Text Searc, SQL Server, SQL Server Analysis Services, and Server Browser are running. SQL Server Agent is disabled.
In Server Surface Area configuration, under Database Engine is running (automatic) and "Remote Connections" is enabled to TCP/IP and named pipes. Analysis Service has Local and Remote connections checked and is running (automatic). SQL Server agent is stopped.
Integration Services is running (Automatic) SQL Server Browser is running. (Automatic)
When I look in the error log, it shows...

I have tried to telnet to port 1434 and 1433 but nothing happens. Does anyone know what else I need to be able to access that port??
Hi. I am trying to put a hugh chunk of text into my database for example information to a particular product which has more than 2000 characters. I had saw this datatype "nvarchar(MAX)" in SQL Server 2005 and was wondering if i can use this to store my text. Thanks
I've installed .NET 2.0 and SQL 2005 express but am unable to locate SQLDMO90.DLL on my machine. I've looked in the expected location (...90inn folder) but it's not there. I've searched the entire drive. Where can I download it?
i installed visual studio'05 on my sys to build cubes in SSAS.But its not having BIDS in its pop-up menu,nor it has BI project templates.Can any one help me out.
I have just successfully published an web app and db to a server but when the web app tries to use a stored procedure it says that it cannot find stored procedure.....in my data base......eeeer anyone had this problem
I want to migrate DB from sybase to SQL server 2012 and i am using SSMA for it. Till yesterday it was working fine. Today when i try connecting sybase i am getting below error.
Unable to find specified provider.Error occurred while establishing connection to Sybase server. If you have 64-bit connectivity components installed on the machine, you can run 64-bit version of SSMA application whose shortcut can be found under the Programs menu. Or you can install the 32-bit connectivity libraries form Sybase product media or download it from Sybase web site.
Hi all, When I try to open a connection it gives me error "Stored Procedure sp_sdidebug not found" Can anyone help me in this respect? I was running the same application with the SQL Server 2005 only earlier when it was running.But now after I reinstalled VS.NET & SQL Server I am getting this error.What could be the problem?
Sorry if this is a simple question, I've not seen any similar posts.
I'm just finished installed SQL 2005 on Vista Business edition (first time for both). I subsequently installed SP2 for 2005.
Upon completing the SP2 installation, the SQL Server Surface Area Configuration manager opened asking me to grant admin rights to the account I used to install the software. The account I used is the local admin account on the machine (only account on the machine as this is my dev box) .
Nothing shows in the two boxes below on this dialog, "Available Privelages" is blank and "Privelages granted is blank".
In addition, if I go to SQL Server Configuration Manager, and click on SQL Server 2005 Services, nothing shows in the right pain. It's as if the software installed, and yet no instance of the database exists or is running.
My thought was that the admin account I used to install the software doesn't have sufficient privelages to to start the SQL Server or SQLBrowser. So I went to computer management, Local Users and groups (machine isn't on a network yet), and made sure this same account is part of the administrators group.
I am able to work fine in my development environment, however when I deploy the application to a clean machine, I get the dreaded "Unable to find the requested .Net Framework Data Provider" error.
I have included the eight dlls required by the Sql Server 2005 CE engine (per the documentation) in the deployment project.
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.
Thanks, Barry G. Sumpter

I tried all the INFORMATION_SCHEMA on SQL 2000 andI see that the system tables hold pretty much everything I aminterested in: Objects names (columns, functions, stored procedures, ...)stored procedure statements in syscomments table.My questions are:If you script your whole database everything you end up havingin the text sql scripts, are those also located in the system tables?That means i could simply read those system tables to get any informationI would normally look in the sql script files?Can i quickly generate a SQL statement of all the indexes on my database?I read many places that Microsoftsays not to modify anything in those tables and not query them since theirstructure might change in future SQL versions.Is it safe to use and rely the system tables?I basically want to do at least fetching of information i want from thesystem tables rather than the SQL script files.I also want to know if it's pretty safe for me to make changes in thesetables.Can i rename an object name for example an Index name, a Stored Procedurename?Can i add a new column in the syscolumns table for a user table?Thank you
I need to setup a script to read all the table names in the database above and then query the database to find the list of Stored Procedure using each table.(SQL Server)
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.

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?
