• Paging Recordsets from SQL Serverside

  - by Jonno

  I've been banging my head off this one for a while. I want to call 1k records from a SQL database and page them per 100. In classic ASP (where I'm moving from) this was dead easy to do with ADODB but with VB using ADO.net I can't find a single way that doesn't involve stored procs (which I want to avoid for now). It seems really stupid to call all 1k and sort it programmatically. Edit: It's SQL Server 2005 / .net 4.0 / Visual Studio 2010. Edit 2: Just to reiterate, I have Googled extensively and don't want to use stored procedures. There are many ways to get paged data but everything I see involves paging the data in the program rather than from the server.

• Select records from XML column (SQL Server 2005) based on node order

  - by jdoe

  I have a column in a SQL Server 2005 table defined as an XML column. Is there a way to select records from this table based on the order of two nodes in that column? For example, we have the following structure in our XML: <item> <latitude/> <longitude/> </item> I want to see if there are any records that have latitude/longitude in the opposite order i.e. <longitude/> then <latitude/>. I've tried some XPath expressions but with no luck.

• Using SQL to get the Last Reply on a Post

  - by Anraiki

  I am trying to replicate a forum function by getting the last reply of a post. For clarity, see PHPBB: there are four columns, and the last column is what I like to replicate. I have my tables created as such: discussion_id (primary key) user_id parent_id comment status pubdate I was thinking of creating a Link Table that would update for each time the post is replied to. The link table would be as follow: discussion_id (primary key) last_user_id last_user_update However, I am hoping that theres a advance query to achieve this method. That is, grabbing each Parent Discussion, and finding the last reply in each of those Parent Discussions. Am I right that there is such a query?

• Exclude records matching subquery

  - by Skudd

  There is probably an obvious answer to this question, but I am having one heck of a time getting anywhere with it. Consider the query: SELECT * FROM reports AS r JOIN reportvalues AS rv ON rv.report_id = r.report_id JOIN metrics AS m ON m.metric_id = rv.metric_id WHERE r.report_id NOT IN( SELECT DISTINCT report_id FROM exclude_report ) In this query, exclude_report is a view constructed in a similar manner. Now what happens is the query takes an EXTREMELY long time to execute, presumably because the subquery is being executed over each and every row in the parent query. However, I am finding no feasible means of doing this any other way. Oh great SQL wizards, please advise. I really need a way of doing this all in SQL, which I will be using in SSRS.

• Unexpected behaviour of Order by clause

  - by Newbie

  I have a table which looks like Col1 col2 col3 col4 col5 1 5 1 4 6 1 4 0 3 7 0 1 5 6 3 1 8 2 1 5 4 3 2 1 4 The script is declare @t table(col1 int, col2 int, col3 int,col4 int,col5 int) insert into @t select 1,5,1,4,6 union all select 1,4,0,3,7 union all select 0,1,5,6,3 union all select 1,8,2,1,5 union all select 4,3,2,1,4 If I do a sorting (ascending), the output is Col1 col2 col3 col4 col5 0 1 5 6 3 1 4 0 3 7 1 5 1 4 6 1 8 2 1 5 4 3 2 1 4 The query is Select * from @t order by col1,col2,col3,col4,col5 But as can be seen that the sorting output is wrong (col2 to col5). I want the output to be every column being sorted in ascending order i.e. Col1 col2 col3 col4 col5 0 1 0 1 3 1 3 1 1 4 1 4 2 3 5 1 5 2 4 6 4 8 5 6 7 Why so and how to overcome this? Thanks in advance

• Microsoft Access vs Native SQL

  - by ktm5124

  Hypothetical: Let's say you are writing complex queries to a database and it is very important that the data you extracted is the correct result set (e.g., that you didn't mess up a JOIN by not using all the correct keys, and all the other things that can go wrong, et cetera). What would you rather use to do this? Would you write the query using Microsoft Access and its Design View, or would you write it in native SQL using a SQL IDE? What is the better professional choice? Thanks in advance your feedback!

• Zip Code to City/State and vice-versa in a database?

  - by Simucal

  I'm new to SQL and relational databases and I have what I would imagine is a common problem. I'm making a website and when each user submits a post they have to provide a location in either a zip code or a City/State. What is the best practice for handling this? Do I simply create a Zip Code and City and State table and query against them or are there ready made solutions for handling this? I'm using SQL Server 2005 if it makes a difference. I need to be able to retrieve a zip code given a city/state or I need to be able to spit out the city state given a zip code.

• Finding group maxes in SQL join result

  - by Gene

  Two SQL tables. One contestant has many entries: Contestants Entries Id Name Id Contestant_Id Score -- ---- -- ------------- ----- 1 Fred 1 3 100 2 Mary 2 3 22 3 Irving 3 1 888 4 Grizelda 4 4 123 5 1 19 6 3 50 Low score wins. Need to retrieve current best scores of all contestants ordered by score: Best Entries Report Name Entry_Id Score ---- -------- ----- Fred 5 19 Irving 2 22 Grizelda 4 123 I can certainly get this done with many queries. My question is whether there's a way to get the result with one, efficient SQL query. I can almost see how to do it with GROUP BY, but not quite. In case it's relevant, the environment is Rails ActiveRecord and PostgreSQL.

• Access DB with SQL Server Back End

  - by uyuni99

  I have an old Access application that has a lot of code in forms and reports. The database is getting too large and I am thinking of moving the back end to SQL Server. My requirements are as follows: The DB needs to be multiuser and the users (3-5) will need to log in over the web I would prefer not to re-write the forms and reports in ASP or some other web front end. When I think about my choices, I see them as: Have an Access ADP front end and allows remote log-in to the server where it is stored. Not sure if it is possible for 2 users to simultaneously log in Distribute an ADP front end to the users, but I am not sure if it is possible to connect to a SQL Server back end over the internet, and the network traffic may be an issue. Any other solution? I appreciate all help. u

• Hibernate HQL to basic SQL

  - by CC

  Hello everybody, I working on a project with Hibernate and we need to replace Hibernate with some "home made persistence" stuff. The idea is that the project is big enough, and we have many HQL queries. The problem is with the queries like select a,b from table1, table2 on t1.table1=t2.table2 Basically all joins are not supported by our "hand made persistence" stuff. What I would need, is to be able to do some sort of transcoder, which will take as a input the HQL queries and output some SQL, but the basic SQL without joins, something like (a dumb example) select a from table1 where t1 IN ( select b from table2) I hope you get the idea. My persistence layer does not supports joins. Does anybody has any idea about something like that? Some framework, or something? Thanks alot everybody. C.C.

• Implications of Fulltext Search over many columns

  - by Alex

  Hello, I have a really wide table which includes separate columns for billing address, shipping address, primary address, names, aliases etc. (I can't normalize this table further, and that's not the question here anyways). I'm implementing SQL Server fulltext search, and I'm wondering whether I should limit the search ability to just the primary fields (primary address and names for example), or if I can extend the search ability across all columns without occurring too much of a performance or memory penalty. I've done some basic testing with 10,000 sample rows and it's quite fast but I don't have much experience with fulltext indexing, especially its dictionary internals, so I don't know if the index is going to grow over time, or if there is anything else to consider. Thoughts?

• Access sql server without directly permission in domain from ASP.NET

  - by Yongwei Xing

  Hi all Here is the situation. All the machines and users are in the same domain.We are in a domain enviroment. There are some sql server 2005/2008 storing data. There is a ASP.NET site in the domain using the Window Authentication. Now, we need read the data from the sql server and display them using SqlDataSource and GridView. But most of users do not have the direct permission to access the database. Is there any solution to get the data from database and display them on the site without granting users permission? Best Regards,

• VBA SQL Loop using QODBC

  - by Dan

  I am trying to loop through an existing table (tblSalesOrder) and I need to run through every line (where they relate to that particular customer) and write each line into an SQL statement and execute it. What is the easiest way to go about this procedure? The number of lines will need to be counted prior to data being written via SQL to a QuickBooks database. I can code something similar in php using the code below, but I am unsure how to convert this into a VBA friendly format: $sql_count = "SELECT count(*) FROM tblSalesOrder WHERE Customer='cust_number'"; execute_query($sql_count) When the above value is greater than 0, the vba code should loop through the queries. Thanks everyone

• SSIS - SharePoint to SQL without Adapter Addin?

  - by Mark

  Hey all, Im looking to Extract a SharePoint List (WSS 2.0) to a SQL(2005) Table using SQL Server Integrated Services. First off I am aware of the "adapter" that does this from http://msdn.microsoft.com/en-us/library/dd365137.aspx however I'm just wondering for compatibility purposes if it can't just be done "out of the box". There are only a limited number of "Data Flow Sources" to select as alternatives and I am unsure if any of these would be able to work in a similar way either directly to SharePoint or via SharePoints web services (e.g. http://server_name/_vti_bin/Lists.asmx) From the list of these sources it looks like the best option would be the OLE DB connector, but not sure how it would do this. Any help you have would be great, Mark

• Handling Timeouts In A Website SQLCommand Object and c#

  - by user341684

  I'm using visual studio 2008 and sql server 2005 and everything is working just fine under normal use. However if a user is on a page for a while several minutes with no activity then clicks a button on occassion the site throws the following exception ... Procedure or Function "sp_name" parameter '@SomeParameterName', which was not supplied I'm also encountering this error in Visual Studio while debugging the application, in otherwords run the site from visual studio then make some change to the html in VS save the changes and refresh the page. The error is not consistent nor is the time the page has to stay idle in order for it to occur.... The current sql command object timeout is 30 secs and the website timeout is 30 minutes. Has anyone else experienced this scenario and what is the fix as I would not except anything to go out of scope until the website timeout occurs ... Any insight will be appreciated.

• Understanding CGI and SQL security from the ground up

  - by Steve

  This question is for learning purposes. Suppose I am writing a simple SQL admin console using CGI and Python. At http://something.com/admin, this admin console should allow me to modify a SQL database (i.e., create and modify tables, and create and modify records) using an ordinary form. In the least secure case, anybody can access http://something.com/admin and modify the database. You can password protect http://something.com/admin. But once you start using the admin console, information is still transmitted in plain text. So then you use HTTPS to secure the transmitted data. Questions: To describe to a learner, how would you incrementally add security to the least secure environment in order to make it most secure? How would you modify/augment my three (possibly erroneous) steps above? What basic tools in Python make your steps possible? Optional: Now that I understand the process, how do sophisticated libraries and frameworks inherently achieve this level of security?

• SQL Server 2008 - Get Geography From Record

  - by user336786

  Hello, I am new to using the geography types in SQL Server 2008. I have a table in my database called "Location". "Location" has the following columns and types: Location -------- City nvarchar(256) State nvarchar(256) PostalCode nvarchar(25) Latitude decimal(9, 6) Longitude decimal(9, 6) Each Location is related to a Store record in my database. I am trying to find the stores within a 10 mile radius or postal code or city/state that a user enters. To accomplish this, I know that I need to rely on geographies. At this time I have: DECLARE @startingPoint geography; SET @startingPoint=geography::STGeomFromText('POINT(-122.34900 47.65100)', 4326); That gives me the starting point from a hard-coded textual value. However, I do not know how to convert a lat/long from my Location table into a geography instance. How do I convert a lat/long in my database to a geography instance so I can continue to work on my query? Thank you!

• SQL Compare-Like tool for Oracle?

  - by Hitchhiker

  We're a .NET team which uses the Oracle DB for a lot of reasons that I won't get into. But deployment has been a bitch. We are manually keeping track of all the changes to the schema in each version, by keeping a record of all the scripts that we run during development. Now, if a developer forgets to check-in his script to the source control after he ran it - which is not that rare - at the end of the iteration we get a great big headache. I hear that SQL Compare by Red-Gate might solve these kind of issues, but it only has SQL Server support. Anybody knows of a similar tool for Oracle? I've been unable to find one.

• Linq To SQL: Retain list order when using .Contains

  - by rockinthesixstring

  I'm using Lucene.net to build a MyListOfIds As List(Of Integer) which I then pass on to my Linq service. I then search the database as follows Return _EventRepository.Read().Where(Function(e) MyListOfIds.Contains(e.ID)).ToList Now I know that Lucene is already ordering MyListOfIds based on the weight it gave each term. What sucks is that Linq is losing that order in it's SQL search. My Question: How can I retain that sort order when building my Lambda expression? I tried using LINQPad to see how the query is being built, but because I had to declare a variable LINQPad didn't show me the resultant SQL :-( Here's what I tried in LINQPad Dim i As New List(Of Integer) i.Add(1) i.Add(100) i.Add(15) i.Add(3) i.Add(123) Dim r = (From e In Events Where i.Contains(e.ID) Select e) note: my example is in VB.NET, but I don't mind if responses are in C#

• Sql Server XML-type column duplicate entry detection

  - by aaaa bbbb

  In Sql Server I am using an XML type column to store a message. I do not want to store duplicate messages. I only will have a few messages per user. I am currently querying the table for these messages, converting the XML to string in my C# code. I then compare the strings with what I am about to insert. Unfortunately, Sql Server pretty-prints the data in the XML typed fields. What you store into the database is not necessarily exactly the same string as what you get back out later. It is functionally equivalent, but may have white space removed, etc. Is there an efficient way to compare an XML string that I am considering inserting with those that are already in the database? As an aside, if I detect a duplicate I need to delete the older message then insert the replacement.
