lookup

I have an ID column in a table in my Reporting Services report. I want to title each page of my report based on a corresponding name field. When I try to create an expression for the group-level PageName property, I see that there is a Lookup() function in SSRS. The example given in the description looks like this: =Lookup(Fields!SaleProdId.Value, Fields!ProductID.Value, Fields!Name.Value, "Product") The problem is that these fields are presumably in the same dataset used to create the report table. In my case, however, the name field is in another dataset of my project. Is there a way to span

I already know that MongoDB doesn't support join operations, but i have to simulate a $lookup (from the aggregation framework) with the mapReduce paradigm. My two collections are: // Employees sample { "_id" : "1234", "first_name" : "John", "last_name" : "Bush", "departments" : [ { "dep_id" : "d001", "hire_date" : "date001" }, { "dep_id" : "d004", "hire_date" : "date004" } ] } { "_id" : "5678", "first_name" : "Johny", "last_name" : "Cash", "departments" : [ { "dep_id" : "d001", "hire_date" : "date03" } ] } { "_id" : "9012", "first_name" : "Susan", "last_name" : "Bowdy", "departments" : [ {

I have a table that I'm trying to populate based on the values of two reference tables. I have various different projects 'Type 1', 'Type 2' etc. that each run for 4 months and cost different amounts depending on when in their life cycle they are. These costings are shown in Ref Table 1 . Ref Table 1 Month | a | b | c | d --------------------------------- Type 1 | 1 | 2 | 3 | 4 Type 2 | 10 | 20 | 30 | 40 Type 3 | 100 | 200 | 300 | 400 Ref Table 2 shows my schedule of projects for the next 3 months. With 2 new ones starting in Jan, one being a Type 1 and the other being a Type 2 . In Feb, I'll

I'm trying to find the best way to implement a QHash-like lookup table that uses multiple keys to return one value. I have read that the Boost library has similar functionality, but I would like to avoid this if possible. An example of what I would like to do is as follows (obviously the following pseudo-code is not possible): //First key (int) - Engine cylinders //Second key (int) - Car weight //Value (int) - Top speed MyLookup<int, int, int> m_Lookup m_Lookup.insert(6, 1000, 210); m_Lookup.insert(6, 1500, 190); m_Lookup.value(6, 1000); //Returns 210 My first (and extremely slow) idea was to

I have one dataset Dataset1 and in that I am displaying data based on grouping. The data is like this CityColumn CountColumn City1 5 City2 3 The query of above datase is like this : select count(*) as "CountColumn" from City group by CityColumn Here in above dataset I have counted using grouping on CityColumn . Now I have created another Dataset Dataset2 and in that The data is like this CityColumn City1 City2 City3 Now in dataset2 I have add one calculated field called TotalCount and used the Lookup Function the function is like this =Lookup(CityColumn, CityColumn, CountColumn, "Dataset1")

I am using a GlassFish-3.1.2 server running in my subnet (192.168.1.3:3700). I already deployed an enterprise app including an EJB in which i defined a business method. Now I want to remotely access the EJB from my java application client. How do i have to setup the JNDI resp. the InitialContext object for doing the lookup of the EJB ? How do I need to define the properties? Btw. I had to run "asadmin enabled-secure-admin" in order to make the GlassFish server work on the LAN. Probably I also need to send my credentials with the properties ? Here's my current "solution", which seems to be

Taking into account the code for C# Console application below, using how should I modify it in order to substitute the line: foreach (Product product in productsByCategory[category]) by the code line foreach (Product product in productsByCategory[category][Id]) ? using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace myQuestion { class Program { static void Main(string[] args) { var products = new List<Product> { new Product { Id = 1, Category = "Garden", Value = 15.0 }, new Product { Id = 1, Category = "Garden", Value = 40.0 }, new Product { Id = 3,
