  • Enums in java compile error

    - by London
    Hi, I'm trying to learn java from bottom up, and I got this great book to read http://www.amazon.com/o/ASIN/0071591060/ca0cc-20 . Now I found example in the book about declaring Enums inside a class but outside any methods so I gave it a shot : Enum CoffeeSize { BIG, HUGE, OVERWHELMING }; In the book its spelled enum and I get this compile message Syntax error, insert ";" to complete BlockStatements Are the Enums that important at all?I mean should I skip it or its possible that I will be using those some day?

  • Why there are no semicolons and {} blocks in some languages

    - by Incognito
    I know the question has no practical value, but it is interesting why in some languages semicolons and {} blocks are removed although their predecessor have them. Actually it makes me nervous to write a code in Python as there are no ";" and {}. Also in new language Google-GO semicolons are also missing although it says that lexer uses a rule to insert semicolons automatically as it scans. So is there any secret :) reason for this.

    - by gsp
    I have a large data file that is creatd from a shell script. Next script processes it by sorting and reading several times, that takes more than 14 hours, it is not viable.

I have to read a group of records everytime, sort and process and write to the output sort file and at the same time insert into db2/sql tables.

  • What does `?` stand for in SQL?

    - by user295189
    I have this SQL by a programmer: $sql = " INSERT INTO `{$database}`.`table` ( `my_id`, `xType`, `subType`, `recordID`, `textarea` ) VALUES ( {$my_id}, ?xType, ?subType, {$recordID}, ?areaText ) "; My question is why is he using ? before values? How do I see what values are coming in? I did echo and it shows ?xType as ?xType. No values. What does ? stand for in SQL?

  • MySQL using function IN with variable

    - by misanov
    I have problem querying table with variable in IN function. SELECT s.date, (SELECT GROUP_CONCAT(value) FROM value WHERE id_value IN(s.ref_values) ) AS vals FROM stats s ORDER BY s.date DESC LIMIT 1 Where s.ref_values is '12,22,54,15'. I get only one return for first number (12). When I insert that value directly in IN(12,22,54,15) it finds all 4. So, there must be problem with using variable in IN. What am I doing wrong?

  • Single entity with single view or two views in mvc3 vs2010?

    - by user2905798
    I have the following entity model public class Employee { public int Employee ID{get;set;} public string employeename{get;set;} public datetime employeeDOb{get;set;} public datetime? employeeDateOfJoin{get;set;} public string empFamilyname{get;set;} public datetime empFamilyDob{get;set;} } here I have to design a view for collecting employee information and employee family information. Since I am working on already available data, where in empFamilyDob was not mandatory. But now it is being made mandatory, the previous data doesn't contain EmpFamilyDob. So naturally I have added this new property EmpFamilyDob to the Model and made it required through DataAnnotations. Now there are two set of views to be developed. 1. A view which simply allows to collect the employee information without employee family information. i.e, empFamilyName and EmpFamilyDob.--This view is used by the Hr section to insert empplyee details Since the empFamilyname and EmpFamilyDob being now made mandatory, some other section will edit the data and update the EmpFamilyName and EmpFamilyDob as and when the information about employee family details are received. I have action controller for CreateNew and Edit Which is being generated by using the default model. There are two user actions being performed. 1.When the user clicks the Create new -- he will be able to update only the Employee information 2.As and when the other section receives the employee family details they update the familyname and family date of birth. i.e, EmployeeFamilyname and EmployeFamilyDob. While creating new record the uses should be able to update employee information only and while editing the information he should be able to update the employeefamily information. Since I have a single view with most of these fields as required and not allowing null , How can I achieve this in a sincle view? I have recorrected the model like this public class Employee { public int Employee ID{get;set;} public string employeename{get;set;} public datetime employeeDOb{get;set;} public datetime? employeeDateOfJoin{get;set;} public string empFamilyname{get;set;} public datetime? empFamilyDob{get;set;} } Now by default I hope the createnew action would insert null value for empFamilyname(string datatype) and empFamilyDob . In the Edit action the user should be made to enter empFamilyname and empFamilyDob(mandatory). As there is every chance that the user might edit other information about the employee(like employeeDob) I don't want to go for partial views. Can you help me out with some illustration. Thanks in advance
