  • c++ std::ostringstream vs std::string::append

    - by NickSoft
    In all examples that use some kind of buffering I see they use stream instead of string. How is std::ostringstream and << operator different than using string.append. Which one is faster and which one uses less resourses (memory). One difference I know is that you can output different types into output stream (like integer) rather than the limited types that string::append accepts. Here is an example: std::ostringstream os; os << "Content-Type: " << contentType << ";charset=" << charset << "\r\n"; std::string header = os.str(); vs std::string header("Content-Type: "); header.append(contentType); header.append(";charset="); header.append(charset); header.append("\r\n"); Obviously using stream is shorter, but I think append returns reference to the string so it can be written like this: std::string header("Content-Type: "); header.append(contentType) .append(";charset=") .append(charset) .append("\r\n"); And with output stream you can do: std::string content; ... os << "Content-Length: " << content.length() << "\r\n"; But what about memory usage and speed? Especially when used in a big loop. Update: To be more clear the question is: Which one should I use and why? Is there situations when one is preferred or the other? For performance and memory ... well I think benchmark is the only way since every implementation could be different. Update 2: Well I don't get clear idea what should I use from the answers which means that any of them will do the job, plus vector. Cubbi did nice benchmark with the addition of Dietmar Kühl that the biggest difference is construction of those objects. If you are looking for an answer you should check that too. I'll wait a bit more for other answers (look previous update) and if I don't get one I think I'll accept Tolga's answer because his suggestion to use vector is already done before which means vector should be less resource hungry.

  • Changing GORM table name

    - by Matthias Hryniszak
    Hi I'm fighting to get the following mapping working in Grails 1.3.1 and MySQL: class Login { int id String email static mappings = { table 'my_table' id column: "Mgr_id" version: false } } No matter what I do the queries that are being issued refer to "schema.login" table instead of "schema.my_table". This is very frustrating... Can anyone answer why this might not be working?

  • How to count how many items for distinct items in mysql?

    - by Vincent Duprez
    Imagine a have a table with a column named status: status ------ A A A B C C D D D How can I count how many rows have A, how many rows have B etc? this kind of output: A |B |C |D |E ------------------ 3 |1 |2 |3 |0 As for E = O , this will always be A,B,C,D and E Output should be one row (thus 1 query). When doing a distinct count (most returning answer on my searches, it does return how many different elements there are, 4 in this case...)

  • Get metadata out of a webHttpBinding endpoint

    - by decyclone
    Hi, With a reference to my previous question, I would like to know how would I extract information of a WCF service from a client application to know what methods/types are exposed if the service exposes only one endpoint that uses webHttpBinding? Just to summarize, in my previous question, I came to know that an endpoint using webHttpBinding does not get exposed in the generated WSDL because it would be a JSON endpoint and is just not compatible.

  • Get name given a phone number on the iPhone

    - by ganti
    I'm using a TextField where the user types a phone number. When the TextField changes, it should check if this number is already in the phonebook and display the name. So far, my only way is to parse all names and number in a Dict and read it from there. Is there a simpler, more efficient and sophisticated way to do that?

  • Character encoding issues?

    - by Santosh
    We had a a clob column in DB. Now when we extract this clob and try to display it (plain text not html), it prints junk some characters on html screen. The character when directly streamed to a file looks like ” (not the usual double quote on regular keyboard) One more observation: System.out.println("”".getBytes()[0]); prints -108. Why a character byte should be in negative range ? Is there any way to display it correctly on a html screen ?

  • If I create a transient property in the model, isn't this managed by core data then?

    - by mystify
    Just to grok this: If I had a transient property, lets say averagePrice, and I mark that as "transient" in the data modeler: This will not be persistet, and no column will be created in SQLite for that? And: If I make my own NSManagedObject subclass with an averagePrice property, does it make any sense to model that property in the xcdatamodel file? Would it make a difference if I would simply create a property in my subclass and not model that in the entity? (I think: yes, it doesn't matter at all ... but not sure)

  • True or False: Good design calls for every table to have a primary key, if nothing else, a running i

    - by Velika
    Consider a grocery store scenario (I'm making this up) where you have FACT records that represent a sale transaction, where the columns of the Fact table include SaleItemFact Table ------------------ CustomerID ProductID Price DistributorID DateOfSale Etc Etc Etc Even if there are duplicates in the table when you consider ALL the keys, I would contend that a surrogate running numeric key (i.e. identity column) should be made up, e.g., TransactionNumber of type Integer. I can see someone arguing that a Fact table might not have a unique key (though I'd invent one and waste the 4 bytes, but how about a dimension table?

  • Can Drupal terms in different Taxonomies be synonymous?

    - by DKinzer
    Let's say Taxonomy_A is associated to Node_Type_A Taxonomy_B is associated to Node_Type_B. AND Both Taxonomy_A and Taxonomy_B have a term called 'yellow'. Is it possible to make terms 'yellow' synonymous, so that if I'm looking at a list of 'yellow' stuff, I'm seeing content of both types (Node_Type_A, and Node_Type_B)?

  • Excel macro to change external data query connections - e.g. point from one database to another

    - by Rory
    I'm looking for a macro/vbs to update all the external data query connections to point at a different server or database. This is a pain to do manually and in versions of Excel before 2007 it sometimes seems impossible to do manually. Anyone have a sample? I see there are different types of connections 'OLEDB' and 'ODBC', so I guess I need to deal with different formats of connection strings?

  • MySQL More Tables or More Rows

    - by Pez Cuckow
    I am working on a game that I am going to open to the public to have on their game. The game stores lots of information (about 300 rows) per website and spends a lot of time updating values within this MySQL database. Is it better (faster/efficient) to add a new table for every website or to just have 1000's of rows in one table and add a column "website_id" or similar?
