  • SQL Server: How to remove empty lines in SSMS?

    - by atricapilla
    I have many .sql files with lots of empty lines e.g. WITH cteTotalSales (SalesPersonID, NetSales) AS ( SELECT SalesPersonID, ROUND(SUM(SubTotal), 2) FROM Sales.SalesOrderHeader WHERE SalesPersonID IS NOT NULL GROUP BY SalesPersonID ) SELECT sp.FirstName + ' ' + sp.LastName AS FullName, sp.City + ', ' + StateProvinceName AS Location, ts.NetSales FROM Sales.vSalesPerson AS sp INNER JOIN cteTotalSales AS ts ON sp.BusinessEntityID = ts.SalesPersonID ORDER BY ts.NetSales DESC Is ther a way to remove these empty lines in SQL Server Management Studio? This is what I would like to have: WITH cteTotalSales (SalesPersonID, NetSales) AS ( SELECT SalesPersonID, ROUND(SUM(SubTotal), 2) FROM Sales.SalesOrderHeader WHERE SalesPersonID IS NOT NULL GROUP BY SalesPersonID ) SELECT sp.FirstName + ' ' + sp.LastName AS FullName, sp.City + ', ' + StateProvinceName AS Location, ts.NetSales FROM Sales.vSalesPerson AS sp INNER JOIN cteTotalSales AS ts ON sp.BusinessEntityID = ts.SalesPersonID ORDER BY ts.NetSales DESC

  • Convert executed SQL result to a list of Model object

    - by huynq9
    I'm wondering that is it possible to convert the executed query result to a list of models. I'm using Ruby with ActiveRecord and need to execute custom SQL query to join two or many tables. The code looks like below: connection = ActiveRecord::Base.connection sql = "select T1.f1, T2.f2 from T1 left join T2 on T1.id = T2.id" @result = connection.execute(sql) In Ruby code, I defined a models to manage the executed SQL result: class Model property :f1, :f2 end Is there any way to convert @result to list of Model object? so I can deal with each item in the list as following @result.each do |item| puts item.f1 puts item.f2 end

  • Thin & Sinatra not taking port

    - by NekoNova
    I'm having problems settig up my application using Thin and Sinatra. I have created a development-config.ru file that contains the following settings: # This is a rack configuration file to fire up the Sinatra application. # This allows better control and configuration as we are using the modular # approach here for controlling our application. # # Extend the Ruby load path with the root of the API and the lib folder # so that we can automatically include all our own custom classes. This makes # the requiring of files a bit cleaner and easier to maintain. # This is basically what rails does as well. # We also store the root of the API in the ENV settings to ensure we have # always access to the root of the API when building paths. ENV['API_ROOT'] = File.dirname(__FILE__) $:.unshift ENV['API_ROOT'] $:.unshift File.expand_path(File.join(ENV['API_ROOT'], 'lib')) $:.unshift File.expand_path(File.join(ENV['API_ROOT'], 'db')) # Now we can require all the gems used for the entire API by simpling requiring # them here. We can also include the classes that we have defined inside the lib # folder. require 'rubygems' require 'bundler' # Run Bundler to setup our gems properly. This will install all the missing gems on # the system and ensure that the deployment environment is ready to run. Bundler.require # To make the loading easier for the application, we will now automatically load all # models that have been defined inside the lib folder. This ensures that we do not need # to load them anymore anywhere else in our application, as the models will be known to # ruby everywhere. Dir.glob(File.join(ENV['API_ROOT'], 'lib', '**', '*.rb')).each{|file| require file} # Now we will configure the Sinatra application so that we can fire up the entire API. # This requires some detailed settings like whether logging is allowed, the port to be # used and some folder locations. require 'sinatra' require 'app' set :logging, true set :dump_errors, true set :port, 3001 set :views, "#{ENV['API_ROOT']}/views" set :public_folder, "#{ENV['API_ROOT']}/public" set :environment, :test # Start up the Sinatra application with all the settings that we have defined. run App.new This is based upon the information I found on the Sinatra website. However, the problem is that I cannot get the application running on port 3001. If I use thin start -R development-config.ru it runs on port 3000. If I use rackup config-development.ru it runs on port 9696. However I never see Sinatra kick in or run over port 3000. My application looks like this: # Author : Arne De Herdt # Email : # This is the actuall application that will be running under Sinatra # to serve the requests for the billing middleware API. # We use the modular approach here to allow control when deploying # the application using Capistrano. require 'sinatra/base' require 'logger' require 'savon' require 'billcrux' class App < Sinatra::Base # This action responds to POST requests on the URI '/billcrux/register' # and is responsible for handeling registration requests with the # BillCrux payment system. # The post "/billcrux/register" do # do stuff end end Can someone tell me what I am doing wrong?

  • How do I select differing rows in two MySQL tables with the same structure?

    - by chiborg
    I have two tables, A and B, that have the same structure (about 30+ fields). Is there a short, elegant way to join these tables and only select rows where one or more columns differ? I could certainly write some script that creates the query with all the column names but maybe there is an SQL-only solution. To put it another way: Is there a short substitute to this: SELECT * FROM table_a a JOIN table_b b ON a.pkey=b.pkey WHERE a.col1 != b.col2 OR a.col2 != b.col2 OR a.col3 != b.col3 # .. repeat for 30 columns

  • linq to sql using foreign keys returning iqueryable(of myEntity]

    - by Gern Blandston
    I'm trying to use Linq to SQL to return an IQueryable(of Project) when using foreign key relationships. Using the below schema, I want to be able to pass in a UserId and get all the projects created for the company the user is associated with. DB tables: Projects Projid ProjCreator FK (UserId from UserInfo table) Companyid FK (CompanyID from Companies table) UserInfo UserID PK Companyid FK Companies CompanyId PK Description I can get the iqueryable(of project) when simply getting the ProjectCreator with this: Return (From p In db.Projects _ Where p.ProjectCreator = Me.UserId) But I'm having trouble getting the syntax to get a iqueryable(of projects) when using foreign keys. Below gives me an IQueryable(of anonymous) but I can't seem to convince it to give me an IQueryable(of project) even if I try to cast it: Dim retval = (From p In db.Projects _ Join c In db.Companies On p.CompanyId Equals c.CompanyId _ Join u In db.UserInfos On u.CompanyId Equals c.CompanyId _ Where u.Login = UserId)

  • SQL Server 2008 full-text search doesn't find word in words?

    - by Martijn
    In the database I have a field with a .mht file. I want to use FTS to search in this document. I got this working, but I'm not satisfied with the result. For example (sorry it's in dutch, but I think you get my point) I will use 2 words: zieken and ziekenhuis. As you can see, the phrase 'zieken' is in the word 'ziekenhuis'. When I search on 'ziekenhuis' I get about 20 results. When I search on 'zieken' I get 7 results. How is this possible? I mean, why doesn't the FTS resturn the minimal results which I get from 'ziekenhuis'? Here's the query I use: SELECT DISTINCT d.DocID 'Id', d.Titel, (SELECT afbeeldinglokatie FROM tbl_Afbeelding WHERE soort = 'beleid') as Pic, 'belDoc' as DocType FROM docs d JOIN kpl_Document_Lokatie dl ON d.DocID = dl.DocID JOIN HandboekLokaties hb ON dl.LokatieID = hb.LokatieID WHERE hb.InstellingID = @instellingId AND ( FREETEXT(d.Doel, @searchstring) OR FREETEXT(d.Toepassingsgebied, @searchstring) OR FREETEXT(d.HtmlDocument, @searchstring) OR FREETEXT (d.extraTabblad, @searchstring) ) AND d.StatusID NOT IN( 1, 5)

  • File IO, Handling CRLF

    - by aCuria
    Hi, i am writing a program that takes a file and splits it up into multiple small files of a user specified size, then join the multiple small files back again. 1) the code must work for c, c++ 2) i am compiling with multiple compilers. I am reading and writing to the files by using the stl functions fread() and fwrite() The problem I am having pertains to CRLF. If the file I am reading from contains CRLF, then I want to retain it when i split and join the files back together. If the file contains LF, then i want to retain LF. Unfortunately, fread() seems to store CRLF as \n (I think), and whatever is written by fwrite() is compiler-dependent. How do i approach this problem? Thanks.

  • DMX Analysis Services question

    - by user282382
    Hi, I am have two mining models, both are time series. One is [Company_Inputs] and the other is [Booking_Projections]. What I want to do is use EXTEND_MODEL_CASES to join the results of [Company_Inputs] as the extended cases. So basically something like: Select Flattened PredictTimeSeries([Bookings], 1, 6, EXTEND_MODEL_CASES) FROM [Booking_Projections] Natural Prediction Join (Select Flattened PredictTimeSeries([Metric1], 1, 6) From [Company_Inputs]) AS T This code of course doesn't work, but the idea is to use the predictions made from [Company_Inputs] as cases for predicting future values of [Booking_Projections] If anyone has an idea of how I can accomplish this I would appreciate it very much.

Thanks

  • Using a temp table in a view

    Hi Everyone I would really like to create a view. I know you can't use temp tables in MSSQL2005 views. Without rewriting the sql, is there anything obvious I've missed?

  • Whats wrong with my SQL query?

    - by William
    I'm trying to set up a query that shows the first post of each thread and is ordered by the date of the last post in each thread. I got the first part down with this query: SELECT * FROM ( SELECT Min( ID ) AS MinID FROM test_posts GROUP BY Thread )tmin JOIN test_posts ON test_posts.ID = tmin.MinID Now I need to figure out how to call the last post of each thread into a table, than use that table to order the first tables results. So far I got this, but it doesn't work.

  • Linq query joining with a subquery

    - by Alan Fisher
    I am trying to reproduce a SQL query using a LINQ to Entities query. The following SQL works fine, I just don't see how to do it in LINQ. I have tried for a few hours today but I'm just missing something. SELECT h.ReqID, rs.RoutingSection FROM ReqHeader h JOIN ReqRoutings rr ON rr.ReqRoutingID = (SELECT TOP 1 r1.ReqRoutingID FROM ReqRoutings r1 WHERE r1.ReqID = h.ReqID ORDER BY r1.ReqRoutingID desc) JOIN ReqRoutingSections rs ON rs.RoutingSectionID = rr.RoutingSectionID Edit*** Here is my table scema- Requisitions: ReqID PK string ReqDate datetime etc... ReqRoutings: ID PK int ReqID FK RoutingSection FK int RoutingDate ReqRoutingSections: Id PK int RoutingSection string The idea is that each Requisition can be routed many times, for my query I need the last RoutingSection to be returned along with the Requisition info. Sample data: Requisitions: - 1 record ReqID 123456 ReqDate '12/1/2012' ReqRoutings: -- 3 records id 1 ReqID 123456 RoutingSection 3 RoutingDate '12/2/2012' id 2 ReqID 123456 RoutingSection 2 RoutingDate '12/3/2012' id 3 ReqID 123456 RoutingSection 4 RoutingDate '12/4/2012' ReqRoutingSections: -- 3 records id 2 Supervision id 3 Safety id 4 Qaulity Control The results of the query would be ReqID = '123456' RoutingSection = 'QualityControl' -- Last RoutingSection requisition was routed to

  • Should I use integer primary IDs?

    - by arthurprs
    For example, I always generate an auto-increment field for the users table, but I also specify a UNIQUE index on their usernames. There are situations that I first need to get the userId for a given username and then execute the desired query, or use a JOIN in the desired query. It's 2 trips to the database or a JOIN vs. a varchar index. Should I use integer primary IDs? Is there a real performance benefit on INT over small VARCHAR indexes?

  • MySQL break out group clause from subquery

    Here is my query SELECT COALESCE(js.name,'Lead saknas'), count(j.id) FROM jobs j LEFT JOIN job_sources js ON j.job_source=js.id LEFT JOIN (SELECT * FROM quotes GROUP BY job_id) q ON j.id=q.job_id GROUP BY j.job_source The problem is that it's allowed for each job to have more than one quote. Because of that i group the quotes by job_id. Now sure, this works. But i don't like the solution with a subquery. How can i break out the group clause from the subquery to the main query? I have tried to add q.job_id to the main group clause, both before and after the existing one but don't get the same results.

  • Hibernate Criteria: Return different entity type than rooted entity?

    - by Gilean
    I have entities similar to: ProductLine: id, name ProductLineContents: content_id, product_line_id Content: id, text, updated_time What I'd like to do is: for each product line, get the latest content (so if theres two content entries associated to one product line, the latest updated_time is rturned, and if one content item is associated to two product lines, it is returned twice). Something similar to: select content.* from productline inner join productlinecontents inner join content; However I can't seem to figure out how to have Hibernate Criteria return a different entity than the original one it was created with. So if I wanted to start the criteria at the product line with createCriteria(ProductLine.class) along with the proper joins, then it only returns ProductLine objects, but I need Content objects. What's the best way to accomplish this? The actual data model is much more complex and can't be modified
