  • ListView: Display data divided into groups?

    - by jawonlee
    I would like to display the contents of a DataTable, divided into several groups depending on the value of one of the columns. So, if I have a DataTable (from SQL query) with: GroupID Name Description 1 foo bar 1 one two 2 some thing I would like to place all records containing GroupID 1 in one div, all records with GroupID 2 in another div, and so on. How can I do this? I'm writing in ASP.NET 4.0, with C# codebehind.

  • SQL Server 2008 2mb Limit for XML??

    - by Nai
    I am trying to output a long XML result from SMSS. When I right click on the results and 'save results as...', I can only get a 2mb file? I have changed the settings in SMSS via Tools - Options - Query Results - SQL Server - Results to Grid, for XML data to be unlimited. Forever, it still seems to be truncating my XML results? So, how can I bypass this problem and output my XML result to a file? Thanks

    - by KeriLynn
    I have a table with my products and I'm trying to write a page that would pull bracelets with certain colors from the database. So here's what I have right now (in php): $query = "SELECT * FROM products WHERE (products.colors LIKE '%black%')"; But I only want to select rows where the value for the column "category" equals "bracelet". I've tried a few different things, but I keep getting warnings and errors. I appreciate any help you can give, thank you!

  • Hibernate (JPA) Entity with Static collection as a member

    - by Kyle Partridge
    Is it possible to have a static collection as a member of a hibernate entity? Say I have an object Question: public class Question { private String category; ... } Would it be possible to populate a static Set<String> that is a distinct set of all categories in the Database? I know I could just query this, but I was wondering if there was a more elegant solution, as it seems like something that other people may have come across.

  • How to save a Stored Procedure ?

    - by Richard77
    Hello, I've been playing today with stored procedures. I'm stoned that I picked the basic of it up so easily. (I'll also try triggers very soon). Now, I'd like to know how to save my SPROC under the stored procedure folder (Programmability - Stored Procedure) so that I can access it by name (eventually from my C# application). So far, when I press the save icon, I'm proposed to save the whole query. That's not what I want. Thanks for helping

  • difference between where and nested queries

    - by Chris H
    I'm not able to figure out the difference between these queries. I'm pretty sure that the first one is an equi-join. I'm not sure how the second one ISN'T the same as the first. The sub query in #2 selects all Ids from S, and then it returns all R's that also have those ID's, no? SELECT R.cname FROM R, S, WHERE R.Id = S.Id SELECT R.cname FROM R WHERE R.Id IN (SELECT S.Id FROM S)

  • R equivalent of SELECT DISTINCT on two or more fields/variables

    - by wahalulu
    Say I have a dataframe df with two or more columns, is there an easy way to use unique() or other R function to create a subset of unique combinations of two or more columns? I know I can use sqldf() and write an easy "SELECT DISTINCT var1, var2, ... varN" query, but I am looking for an R way of doing this. It occurred to me to try ftable coerced to a dataframe and use the field names, but I also get the cross tabulations of combinations that don't exist in the dataset: uniques <- as.data.frame(ftable(df$var1, df$var2))

  • Confused about distinct/aggregate queries with (N)Hibernate

    - by nw
    I'm not sure how to approach queries that don't map 1:1 to my persistent entities - in other words, distinct and aggregate queries. For example, I need to retrieve a distinct list of property values for populating a drop-down list. Should I write a class and a mapping for the "entities" that are returned by this query? Or should I just use the native DB provider and work with native data sets instead?

  • Multithreaded ActiveRecord requests in rspec

    - by jeem
    I'm trying to recreate a race condition in a test, so I can try out some solutions. I find that in the threads I create in my test, ActiveRecord always returns 0 for counts and nil for finds. For example, with 3 rows in the table "foos": it "whatever" do puts Foo.count 5.times do Thread.new do puts Foo.count end end end will print 3 0 0 0 0 0 test.log shows the expected query, the expected 6 times: SELECT count(*) AS count_all FROM `active_agents` Any idea what's going on here?

  • "Ambiguous column name" error on one particular server

    - by jazbit
    This simple query throws the "Ambiguous column name TaskID" error on one db-server only. This is ridiculous. We tested this with the same database structure on different servers and different versions of ms sql (2005/2008), and it's only THIS particular client's server that throws the error. I'm actually frustrated. SELECT Tasks.TaskID FROM Tasks INNER JOIN TaskHelpers ON TaskHelpers.TaskID = Tasks.TaskID order by TaskID Yes, I know I can put "Tasks.TaskID" into the order by clause, but for some reasons I can't.
