  • What is the point declaring variables at the end of class?

    - by serhio
    I saw multiple examples in MSDN that uses to declare the internal fields at the end of the class. What is the point? I find this a little embarrassing, because each time Visual Studio adds a method it adds it to the end of the class, so there is need every time to move it... class A { public A(){} // Methods, Properties, etc ... private string name; } class A { private string name; public A(){} // Methods, Properties, etc ... }

  • Fastest method for SQL Server inserts, updates, selects

    - by Ian
    I use SPs and this isn't an SP vs code-behind "Build your SQL command" question. I'm looking for a high-throughput method for a backend app that handles many small transactions. I use SQLDataReader for most of the returns since forward only works in most cases for me. I've seen it done many ways, and used most of them myself. Methods that define and accept the stored procedure parameters as parameters themselves and build using cmd.Parameters.Add (with or without specifying the DB value type and/or length) Assembling your SP params and their values into an array or hashtable, then passing to a more abstract method that parses the collection and then runs cmd.Parameters.Add Classes that represent tables, initializing the class upon need, setting the public properties that represent the table fields, and calling methods like Save, Load, etc I'm sure there are others I've seen but can't think of at the moment as well. I'm open to all suggestions.

  • Grails searchable plugin with hasMany

    - by user2624442
    I am using grails searchable plugin to search my domain classes. However, I cannot yet search by my hasMany (skills and interests) fields even though they are of the simple type String. This is my domain class: class EmpactUser { static searchable = [except: ['dateCreated','password','enabled','accountExpired','accountLocked','passwordExpired']] String username String password boolean enabled = true boolean accountExpired boolean accountLocked boolean passwordExpired String email String firstName String lastName String address String phoneNumber String description byte[] avatar byte[] resume Date dateCreated static hasMany = [ skills : String, interests : String, // each user has the ability to list many skills and interests so that they can be matched with a project. ] static constraints = { username blank: false, unique: true password blank: false email email: true, blank: false firstName blank: false lastName blank: false description nullable: true address nullable: true avatar nullable: true, maxSize: 1024 * 1024 * 10 resume nullable: true, maxSize: 1024 * 1024 * 10 phoneNumber nullable: true, matches: "/[(][+]d{3}[)]d+/", maxSize: 30 } } This is the code I am using to search: def empactUserList = EmpactUser.search( searchQuery, [reload: false, result: "every", defaultOperator: "or"]) Am I missing something? Thanks, Alan.

  • Does this make any sense (Apple-documentation)?

    - by Paperflyer
    Here is a snippet of the official Apple Documentation of AudioBufferList (Core Audio Data Types Reference) AudioBufferList Holds a variable length array of AudioBuffer structures. struct AudioBufferList { UInt32 mNumberBuffers; AudioBuffer mBuffers[1]; }; typedef struct AudioBufferList AudioBufferList; Fields mNumberBuffers The number of AudioBuffer structures in the mBuffers array. mBuffers A variable length array of AudioBuffer structures. If mBuffers is defined as AudioBuffer[1] it is not of variable length and thus mNumberBuffers is implicitly defined as 1. Do I miss something here or is this just nonsense?

  • Handling missing data

    - by soppotare
    Say I have a simple helpdesk application which logs calls made by users. I would typically have such fields in a table relating to the call e.g. CallID, Description, CustomerID etc. I Would also have a table of customers including CustomerID, Username, Password, FullName etc. Now when a user is deleted from the customers table then the inner join between the calls table and the users table to find out historically which user logged a call would produce no results. How do people usually deal with this? Have seperate customer and useraccount tables Just disable the accounts so the data is still available Record the customers name in the calls table as a seperate field. or any other methods / suggestions?

  • How do stop form posting to mysql if database contains a specific ID?

    - by user342391
    I have a form that I am using to post data to mysql. Before submitting the form I want to check the database and see if there are any fields in the column 'customerid' that equal 'userid' and if so not to post the form. Basically, I am trying to limit my users from posting more than once. Users will be able to login to my system and make ONE post. They will be able to delete and modify their post but are only limited to one post. How would I do this??? Code so far: <?php include '../login/dbc.php'; page_protect(); $userid = $_SESSION['user_id']; $sql="INSERT INTO content (customerid, weburl, title, description) VALUES ('$_POST[userid]','$_POST[webaddress]','$_POST[pagetitle]','$_POST[pagedescription]')"; if (!mysql_query($sql)) { die('Error: ' . mysql_error()); } echo "1 record added"; ?>

  • How to change particular column entries in a mysql table when uploading data from csv file?

    - by understack
    I upload data into a mysql table from csv file in a standard way like this: TRUNCATE TABLE table_name; load data local infile '/path/to/file/file_name.csv' into table table_name fields terminated by ',' enclosed by '"' lines terminated by '\r\n' (id, name, type, deleted); All 'deleted' column entries in csv file has either 'current' or 'deleted' value. Question: When csv data is being loaded into table, I want to put current date in table for all those corresponding 'deleted' entries in csv file. And null for 'current' entries. How can I do this? Example: csv file: id_1, name_1, type_1, current id_2, name_1, type_2, deleted id_3, name_3, type_3, current Table after loading this data should look like this: id_1, name_1, type_1, null id_2, name_1, type_2, 2010-05-10 id_3, name_3, type_3, null Edit Probably, I could run another separate query after loading csv file. Wondering if it could be done in same query?

  • NSMutableArray of Objects misbehaves ...

    - by iFloh
    I hope someone understands what happens to my NSMutableArray. I read records a, b, c, d from a database, load the fields into an object an add the object to an array. To do this I read the records into an instance of that object (tmpEvent) and add the Object to the target array (NSMutableArray myArray). the code looks like: for (condition) { tmpEvent.field1 = [NSString stringWithUTF8String:(char*)sqlite3_column_text(stmt, 0)]; tmpEvent.field2 = [NSString stringWithUTF8String:(char*)sqlite3_column_text(stmt, 1)]; tmpEvent.field3 = [NSString stringWithUTF8String:(char*)sqlite3_column_text(stmt, 2)]; NSLog(@"myArray: adding %@", tmpEvent.field1); [myArray addObject:tmpEvent]; } The NSLog shows myArray: adding a myArray: adding b myArray: adding c myArray: adding d Subsequent I enumerate the array (this can be in the same or a different method): for (myObject *records in myArray) { NSLog(@"iEvents value %@", records.field1); } The NSLog now shows: myArray value d myArray value d myArray value d myArray value d a mystery .... ??? any thoughts?

  • fields_for to stop pluralizing.

    - by Dmitriy Likhten
    I have a fields_for tag, where I specify the prefix (lets say for some good reasons), and this is supposed to represent a one-to-one relationship. I am trying to represent a relationship widget has_many thingamagigs thingamagig has_one whatchamacallit The field_for code is: fields_for "widgt[thingamagigs_attributes][][whatchamacallit_attributes]", thingamagig.whatchamacallit do |x| which generates names (wrongly): widget[thingamagigs_attributes][][whatchamacallit_attributes][][value] The better solution would be t.fields_for :whatchamacallit do |x| where t = fields_for the thingamagig... However if I do that, the following names are generated widgt[thingamagigs_attributes][whatchamacallit_attributes][] which is completely wrong as all other fields for a thingamagig is... widgt[thingamagigs_attributes][][name] So in all cases I am screwed. The original field_for using a string cannot be used with accepts_nested_attributes_for :whatchamacallit since whatchamacallit is a singular relationship and an object is expected not an array. The second fields_for will simply not work because rails cannot parse the params object correctly. Is there a way to tell the first forms_for to not add the [] after [whatchamacallit_attributes] in all field names?

  • Proper chart scaling in Reporting Services 2005

    - by lastas
    I'm developing a simple bar-chart in Reporting Services 2005 with a stored procedure as data-source. The values in this graph can be both positive and negative, and can span a very big range, and hence I cannot specify any non-dynamic scale that will work for all scenarios. The problem I'm facing is that the automatic scaling pretty much sucks. I get no line to show where the zero-point is, and the y-scale labels are from top to bottom: 8818 -191181 -391181 etc etc... So my question is, what is the best approach to make the scale more adapted to human reading? Is there any guide out there? Does reporting services 2008 handle this better? Also, moving away from Reporting Services is not really an option. I realize how to put values and expression in the max, min, and the gridline interval fields, although its more of a question what expressions I should put there.

  • Why are my Lucene Document results empty?

    - by vegashacker
    I'm running a simple test--trying to index something and then search for it. I index a simple document, but then when a search for a string in it, I get back what looks to be an empty document (it has no fields). Lucene seems to be doing something, because if I search for a word that's not in the document, it returns 0 results. Any reason why Lucene would reliably return a document when it finds one that matches the given query, and yet that document has nothing in it? Thanks! PS: I'm actually running Lucandra (Lucene + Cassandra). That certainly may be a relevant detail, but not sure.

  • Map a property in the entity framework to a different type

    - by Tom
    I have a SQL Server 2008 database. I have a bunch of fields in TableA that are just strings that corresponds to booleans. So every value is either true or false. The edmx I generated using Entity Framework 4.0 has them as strings. This is technically correct but I would like to have them mapped as Booleans instead. Is this possible? If so how can I accomplish this? Thanks much!

  • Need help with jquery sorting

    - by Klerk
    I have a column within which are multiple 'records' (each a div). Each record has a bunch of fields (each a span whose id is the fieldname). I want to allow the user to sort all the records based on a field. I also want, the field that has been sorted to be moved to the beginning of the record. So I came up with this. But its really slow for a large sets. Not sure whats the best way to do this. Any ideas? $(".col1 div").sort( function (a,b) { if($(a).children("."+field).text() > $(b).children("."+field).text()) return -1; else return 1; }).appendTo(".col1");

  • Why is it inserting 0's instead of blank spaces into my DB using php?

    - by zeckdude
    I have an insert: $sql = 'INSERT into orders SET fax_int_prefix = "'.$_SESSION['fax_int_prefix'].'", fax_prefix = "'.$_SESSION['fax_prefix'].'", fax_first = "'.$_SESSION['fax_first'].'", fax_last = "'.$_SESSION['fax_last']; The value of all of these fields is that they are blank right before the insert. Here is an example of one of them I echo'd out just before the insert: $_SESSION[fax_prefix] = For some reason it inserts the integer 0, instead of a blank value or null, as it should. Why is it inserting 0's instead of blank spaces into my DB?

  • JQuery validation based on class?

    - by Mark Kadlec
    I have a form that will have dynamically created elements, one of those will be of date type. There can also be many fields of this type on my form, all which must be validated. I am using a strongly typed view in Asp MVC, so the name will change based on various factors. What I would like to do is validate based on a class name instead, since that will be constant for that type of field. Ie: <%= Html.TextBox("questionAnswers[" + index + "].AnswerValue", qa.AnswerValue, new { @class = "DateTypeClass" })%> So then I would need JQuery validation based on the classname DateTypeClass versus the Name. Any ideas?

  • Getting changes in one column of an historical table

    - by Javi
    Hello, I have a table which stores historical data. It's mapped to an Entity with the following fields (I use JPA with Hibernate implementation): @Entity @Table(name="items_historical") public class ItemHistory{ private Integer id; private Date date; @Enumerated(EnumType.ORDINAL) private StatusEnum status @ManyToOne(optional=false) private User user; @ManyToOne(optional=false) private Item item; } public enum StatusEnum { OK, BAD,...//my status } In every row I store historical data of another table. I need to get the list of the changes on "status" column: the status, the date and the previous status on a specified item (It would be good as well getting the status and date when status was changed). I don't know if this is possible by using HQL. Thanks.

  • How to insert the recently inserteddata of a table to others DB's Table? See description...

    - by Parth
    I am using MySQL DB and I have created a PHP script for the following, now i need the idea for the below asked question.... please help... I have a table called audit trail whose structure is: id, trackid, table, operation, newvalue, oldvalue, field, changedone I have created triggers for insert/update/delete for every table of same DB, now whenever there is change in ny DB the triggers get activated and updates the Audit trail table accordingly.. I am tracking these changes so that i can use these changes to be done on production DB which is of same structure as of this test DB. Also when the admin finds that he does not need the changes recently he did for production DB then he can rollback it using the Old Data it stored in Ausittrail table of test db. Now here in audit trail table structure, there will be an insert for every single field change like-wise if a table has 4 fields then the change in that tavle will insert 4 rows in audit trail.. Coming to the question now, How can i find the latest change done from the Audit table so that I can insert these changes in Production DB.

  • Create ordering in a MySQL table without using a number (because then it's hard to put something in

    - by user347256
    I have a long list of items (say, a few million items) in a mysql table, let's call it mytable and it has the field mytable.itemid. The items are given an order, and can be re=ordered by the user by drag and drop. If I add a field called mytable.order and just put numbers in them, it creates problems: what if I want to move an item between 2 other items? Then all the order fields have to be updated? That seems like a nightmare. Is there a (scalable) way to add order to a table that is different from just giving every item a number, order by that, and do loads of SQL queries everytime the order is changed?

  • Where does one get data like Country:(list) State:(list)

    - by rlb.usa
    As a programmer of data-entry forms of all kinds, I often find myself making fields for things like Country: <choose from list>, State: <choose from list>, Race/Ethnicity: <choose from list>. Consider: Perhaps a list the 50 United States names is an easy thing to find (does one include DC?) , but the countries are not. Nearly every site you find has a differing list with all of the political goings on over the years, and they become outdated quickly. What's the best/common practice regarding population of these kinds of lists? Where does this data come from if it's not given in the specs?
