  • excel:mysql: rs.Update not working

    - by every_answer_gets_a_point
    i am updating a table using an ODBC connection from excel to mysql unfortunately the only column that gets updated is this one: .Fields("instrument") = "NA" where i am assigning variables to .Fields, it is putting NULL values!! what is going on here? here's the code Option Explicit Dim oConn As ADODB.Connection Private Sub ConnectDB() Set oConn = New ADODB.Connection oConn.Open "DRIVER={MySQL ODBC 5.1 Driver};" & _ "SERVER=localhost;" & _ "DATABASE=employees;" & _ "USER=root;" & _ "PASSWORD=pas;" & _ "Option=3" End Sub Function esc(txt As String) esc = Trim(Replace(txt, "'", "\'")) End Function Private Sub InsertData() Dim dpath, atime, rtime, lcalib, aname, rname, bstate, instrument As String Dim rs As ADODB.Recordset Set rs = New ADODB.Recordset ConnectDB With wsBooks rs.Open "batchinfo", oConn, adOpenKeyset, adLockOptimistic, adCmdTable Worksheets.Item("Report 1").Select dpath = Trim(Range("B2").Text) atime = Trim(Range("B3").Text) rtime = Trim(Range("B4").Text) lcalib = Trim(Range("B5").Text) aname = Trim(Range("B6").Text) rname = Trim(Range("B7").Text) bstate = Trim(Range("B8").Text) ' instrument = GetInstrFromXML(wbBook.FullName) With rs .AddNew ' create a new record ' add values to each field in the record .Fields("datapath") = dpath .Fields("analysistime") = atime .Fields("reporttime") = rtime .Fields("lastcalib") = lcalib .Fields("analystname") = aname .Fields("reportname") = rname .Fields("batchstate") = bstate .Fields("instrument") = "NA" .Update ' stores the new record End With ' get the last id Set rs = oConn.Execute("SELECT @@identity", , adCmdText) 'MsgBox capture_id rs.Close Set rs = Nothing End With End Sub

  • What job title should be most suitable for my object in resume and what salary range should I expect

    - by user354177
    I was a classic asp developer in 2000. After a year of full-time employment, I left the field. I found a part-time position as an asp developer again in 2005 and taught myself vb.net. In 2007, I got the current full-time job as an Asp.net web developer. I taught myself C#, LING t0 SQL, Web Services, AJAX, and creating all kinds of reports with reporting services. One and half years ago, I sent myself to part-time graduate program in Database and Web Systems. I'll have two semesters to go and so far my GPA is 4.0/4.0. My job responsibility is to collect business requirements from other departments, design the database, write stored procedures, create aspx pages, and create reports. I love what I do and want to advance my career to the next level. What I enjoy most is to design the relational database. I would want to become an .Net Architect eventually. I got an interview. They were looking for asp.net web developer. But I was surprised and disappointed that position would only create aspx pages. I would not even have opportunity to write stored procedures, let alone design the database (those would be provided by another group). Furthermore, they asked me some detailed questions about web forms, some of which I did not know the answers. they might be disappointed as well. I am eager to learn and can apply what I learn to real projects right away. I believe no matter what specific skills I am lacking for a new position, I can catch up quickly. I am looking for $70k range job. The object in my resume is Experience C# Web Application Developer. Due to the experience from last interview, I wonder if the object is really what I want. Could somebody answer my questions? Thank you.

  • Hibernate Performance Best Practice?

    - by user829237
    Im writing a Web application using Hibernate 3. So, after a while i noticed that something was slow. So i tested hibernate profiler and found that hibernate will make unreasonably many db-calls for simple operation. The reason is ofcourse that i load an Object (this object has several "parents") and these "parents" have other "parents". So basicly hibernate loads them all, even though i just need the basic object. Ok, so i looked into lazy-loading. Which lead me into the Lazyloading-exception, because i have a MVC webapp. So now i'm a bit confused as to what is my best approach to this. Basicly all I need is to update a single field on an object. I already have the object-key. Should I: 1. Dig into Lazy-loading. And then rewrite my app for a open-session-view? 2. Dig into lazy-loading. And then rewrite my dao's to be more specific. E.g. writing DAO-methods that will return objects instanciated with only whats necessary for each use-case? Could be a lot of extra methods... 3. Scratch hibernate and do it myself? 4. Cant really think of other solutions right now. Any suggestions? What is the best practice?

  • jquery autocomplete extra spaces

    - by elasticrash
    I got this loop in a jsp file <% for (int i = 0; i < length; i++) { for( int j = 0; j < width; j++) { element = MAP_LIST[j][i]; if (element.equals("A")) {} else if (j == width-1 && i == length-1){ %> <%=element%><%} else { %> <%=element%>,<%} } } %> which gets me a csv list from an oracle database for my autocomplete text field by using jquery function Mapsheets(type,nomos) { $(function() { var f_data; $.get('/gaec_web/MapSheets.jsp',{'datasrc-select':datasource, 'type_1': type, 'nomos': nomos}, function(data){ f_data = data.split(','); $( "#fx_no" ).autocomplete({ source: f_data, minLength: 2 }); }); }); } everything works like a charm, i type the first 2 chars and the autocomplete pops up displays every thing as it was supposed to and when I try to pick a value i get the value with several (5) extra spaces in the tail. And then when it gets submitted it fails cause it doesnt match the mapname in question. the results look like this " 320-197" So what is causing this? if i run the jsp page alone also get normal results for example 372-146, 376-146, 372-149, 368-149, 376-149, 380-149, 380-152, 376-152, 372-152, 368-152, 368-155, 376-155, 372-155, 380-155, 368-158, 380-158, 376-158, 372-158 thanks in advance

  • WP_Insert_Post and GUID Issue [Wordpress]

    - by morningglory
    Hello, I have a posting form at my theme. I used wp_insert_post there. My code looks like this $post = array( 'ID' => '', 'post_author' => $post_author, 'post_category' => $post_category, 'post_content' => $post_content, 'post_title' => $post_title, 'post_status' => 'publish', ); $post_id = wp_insert_post($post); $fullpost = get_post($post_id); wp_redirect($fullpost->guid); Everything works fine. But when it's inserted to the database, at the GUID field, the entry format is like this permalinks_structure/id. So if my permalinks_structure is like /category/id , it become like http://www.example.com/uncategorized/1. So the problem is, if i post through wordpress admin panel, GUID of the post is http://www.example.com?p=1 . So my post database GUID become mess, because if i want to change permalinks_structure , the post which becomes from outside form will follow the structure. What I want to do is, I want to get the GUID like that I posted through admin panel which is http://www.example.com?p=1 How can i do it ? Please point me out. Thank you.

  • Copy not null and not empty fields from one object to another object of the same type(Objects are same type) in java

    - by Chinni
    I am using hibernate, struts, extjs in my project. I have a Customer object with these fields: custId, custName, address, phone and in my project from UI side I get an object customer with custName. So I need to update the above object(custName is unique). I have only one object with the same customer name. So I will get that object using customer name (object from DB). Now I have to save the object with the updated customer name. If I save as follows I have Customer Object from UI, is cust Customer cust1 = getCustomerByName(cust.getCustName()); cust.setCustId(cust1.getCustId()); save(cust); If I do this I lose the customer address and phone number. So, how can I copy one object not null or not empty field values to another object of same type. Can any one please help. I just stuck here. It's stopping me to save. Thanks in advance!

  • Why does false invalidate validates_presence_of?

    - by DJTripleThreat
    Ok steps to reproduce this: prompt> rails test_app prompt> cd test_app prompt> script/generate model event_service published:boolean then go into the migration and add not null and default published to false: class CreateEventServices < ActiveRecord::Migration def self.up create_table :event_services do |t| t.boolean :published, :null => false, :default => false t.timestamps end end def self.down drop_table :event_services end end now migrate your changes and run your tests: prompt>rake db:migrate prompt>rake You should get no errors at this time. Now edit the model so that you validate_presence_of published: class EventService < ActiveRecord::Base validates_presence_of :published end Now edit the unit test event_service_test.rb: require 'test_helper' class EventServiceTest < ActiveSupport::TestCase test "the truth" do e = EventServer.new e.published = false assert e.valid? end end and run rake: prompt>rake You will get an error in the test. Now set e.published to true and rerun the test. IT WORKS! I think this probably has something to do with the field being boolean but I can't figure it out. Is this a bug in rails? or am I doing something wrong?

  • Sending a message to nil?

    - by Ryan Delucchi
    As a Java developer who is reading Apple's Objective-C 2.0 documentation: I wonder as to what sending a message to nil means - let alone how it is actually useful. Taking an excerpt from the documentation: There are several patterns in Cocoa that take advantage of this fact. The value returned from a message to nil may also be valid: If the method returns an object, any pointer type, any integer scalar of size less than or equal to sizeof(void*), a float, a double, a long double, or a long long, then a message sent to nil returns 0. If the method returns a struct, as defined by the Mac OS X ABI Function Call Guide to be returned in registers, then a message sent to nil returns 0.0 for every field in the data structure. Other struct data types will not be filled with zeros. If the method returns anything other than the aforementioned value types the return value of a message sent to nil is undefined. Has Java rendered my brain incapable of grokking the explanation above? Or is there something that I am missing that would make this as clear as glass? Note: Yes, I do get the idea of messages/receivers in Objective-C, I am simply confused about a receiver that happens to be nil.

  • PHP form validation function

    - by Barbs
    I am currently writing some PHP form validation (I have already validated clientside) and have some repetitive code that I think would work well in a nice little PHP function. However I have having trouble getting it to work. I'm sure it's just a matter of syntax but I just can't nail it down. Any help appreciated. //Validate phone number field to ensure 8 digits, no spaces. if(0 === preg_match("/^[0-9]{8}$/",$_POST['Phone']) { $errors['Phone'] = "Incorrect format for 'Phone'"; } if(!$errors) { //Do some stuff here.... } I found that I was writing the validation code a lot and I could save some time and some lines of code by creating a function. //Validate Function function validate($regex,$index,$message) { if(0 === preg_match($regex,$_POST[$index],$message) { $errors[$index] = $message; } And call it like so.... validate("/^[0-9]{8}$/","Phone","Incorrect format for Phone"); Can anyone see why this wouldn't work? Note I have disabled the client side validation while I work on this to try to trigger the error, so the value I am sending for 'Phone' is invalid.

  • Modifying Django's pre_save/post_save Data

    - by Rodrogo
    Hi, I'm having a hard time to grasp this post_save/pre_save signals from django. What happens is that my model has a field called status and when a entry to this model is added/saved, it's status must be changed accordingly with some condition. My model looks like this: class Ticket(models.Model): (...) status = models.CharField(max_length=1,choices=OFFERT_STATUS, default='O') And my signal handler, configured for pre_save: def ticket_handler(sender, **kwargs): ticket = kwargs['instance'] (...) if someOtherCondition: ticket.status = 'C' Now, what happens if I put aticket.save() just bellow this last line if statement is a huge iteration black hole, since this action calls the signal itself. And this problem happens in both pre_save and post_save. Well... I guess that the capability of altering a entry before (or even after) saving it is pretty common in django's universe. So, what I'm doing wrong here? Is the Signals the wrong approach or I'm missing something else here? Also, would it be possible to, once this pre_save/post_save function is triggered, to access another model's instance and change a specific row entry on that? Thanks

  • How do I sort an activerecord result set on a i18n translated column?

    - by PlanetMaster
    Hi, I have the following line in a view: <%= f.select(:province_id, options_from_collection_for_select(Province.find(:all, :conditions => { :country_id => @property.country_id }, :order => "provinces.name ASC"), :id, :name) %> In the province model I have the following: def name I18n.t(super) end Problem is that the :name field is translated (through the province model) and that the ordering is done by activerecord on the english name. The non-english result set can be wrongly sorted this way. We have a province in Belgium called 'Oost-Vlaanderen'. In english that is 'East-Flanders". Not good for sorting:) I need something like this, but it does not work: <%= f.select(:province_id, options_from_collection_for_select(Province.find(:all, :conditions => { :country_id => @property.country_id }, :order => "provinces.I18n.t(name) ASC"), :id, :name) %> What would be the best approach to solve this? As you may have noticed, my coding knowledge is very limited, sorry for that.

  • Saving information in the IO System

    - by djTeller
    Hi Kernel Gurus, I need to write a kernel module that simulate a "multicaster" Using the /proc file system. Basically it need to support the following scenarios: 1) allow one write access to the /proc file and many read accesses to the /proc file. 2) The module should have a buffer of the contents last successful write. Each write should be matched by a read from all reader. Consider scenario 2, a writer wrote something and there are two readers (A and B), A read the content of the buffer, and then A tried to read again, in this case it should go into a wait_queue and wait for the next message, it should not get the same buffer again. I need to keep a map of all the pid's that already read the current buffer, and in case they try to read again and the buffer was not changed, they should be blocked until there is a new buffer. I'm trying to figure it there is a way i can save that info without a map. I heard there are some redundant fields inside the I/O system the I can use to flag a process if it already read the current buffer. Can someone give me a tip where should i look for that field ? how can i save info on the current process without keeping a "map" of pid's and buffers ? Thanks!

  • Best way to store data in database when you don't know the type

    - by stiank81
    I have a table in my database that represents datafields in a custom form. The DataField gives some representation of what kind of control it should be represented with, and what value type it should take. Simplified you can say that I have 2 entities in this table - Textbox taking any string and Textbox only taking numbers. Now I have the different values stored in a separate table, referencing the datafield definition. What is the best way to store the data value here, when the type differs? One possible solution is to have the FieldValue table hold one field per possible value type. Now this would certainly be redundant, but at least I would get the value stored in its correct form - simplifying queries later. FieldValue ---------- Id DataFieldId IntValue DoubleValue BoolValue DataValue .. Another possibility is just storing everything as String, and casting this in the queries. I am using .Net with NHibernate, and I see that at least here there is a Projections.Cast that can be used to cast e.g. string to int in the query. Either way in these two solutions I need to know which type to use when doing the query, but I will know that from the DataField, so that won't be a problem. Anyway; I don't think any of these solutions sounds good. Are they? Or is there a better way?

  • Optional mix of filter parameters in a search the Rails way.

    - by GSP
    I've got a simple list page with a couple of search filters status which is a simple enumeration and a test query which I want to compare against both the title and description field of my model. In my controller, I want to do something like this: def index conditions = {} conditions[:status] = params[:status] if params[:status] and !params[:status].empty? conditions[???] = ["(descr = ? or title = ?)", params[:q], params[:q]] if params[:q] and !params[:q].empty? @items = Item.find(:all, :conditions => conditions) end Unfortunately, it doesn't look like I can mix the two types of conditions (the hash and the paramatized version). Is there a "Rails Way" of doing this or do I simply have to do something awful like this: has_status = params[:status] and !params[:status].empty? has_text = params[:q] and !params[:q].empty? if has_status and !has_text # build paramatized condition with just the status elsif has_text and !has_status # build paramatized condition with just the text query elsif has_text and has_status # build paramatized condition with both else # build paramatized condition with neither end I'm migrating from Hibernate and Criteria so forgive me if I'm not thinking of this correctly...

  • Populate an Object Model from a data dataTable(C#3.0)

    - by Newbie
    I have a situation I am getting data from some external sources and is populating into the datatable. The data looks like this DATE WEEK FACTOR 3/26/2010 1 RM_GLOBAL_EQUITY 3/26/2010 1 RM_GLOBAL_GROWTH 3/26/2010 2 RM_GLOBAL_VALUE 3/26/2010 2 RM_GLOBAL_SIZE 3/26/2010 2 RM_GLOBAL_MOMENTUM 3/26/2010 3 RM_GLOBAL_HIST_BETA I have a object model like this public class FactorReturn { public int WeekNo { get; set; } public DateTime WeekDate { get; set; } public Dictionary<string, decimal> FactorCollection { get; set; } } As can be seen that the Date field is always constant. And a single(means unique) week can have multiple FACTORS. i.e. For a date(3/26/2010), for Week No. 1, there are two FACTORS(RM_GLOBAL_EQUITY and RM_GLOBAL_GROWTH). Similarly, For a date(3/26/2010), for Week No. 2, there are three FACTORS(RM_GLOBAL_VALUE , RM_GLOBAL_SIZE and RM_GLOBAL_MOMENTUM ). Now we need to populate this data into our object model. The final output will be WeekDate: 3/26/2010 WeekNo : 1 FactorCollection : RM_GLOBAL_EQUITY FactorCollection : RM_GLOBAL_GROWTH WeekNo : 2 FactorCollection : RM_GLOBAL_VALUE FactorCollection : RM_GLOBAL_SIZE FactorCollection : RM_GLOBAL_MOMENTUM WeekNo : 3 FactorCollection : RM_GLOBAL_HIST_BETA That is, overall only 1 single collection, where the Factor type will vary depending on week numbers. I have tried but of useless. Nothing works. Could you please help me?. I feel it is very tough I am using C# 3.0 Thanks

  • Ensure that all getter methods were called in a JUnit test

    - by Freiheit
    I have a class that uses XStream and is used as a transfer format for my application. I am writing tests for other classes that map this transfer format to and from a different messaging standard. I would like to ensure that all getters on my class are called within a test to ensure that if a new field is added, my test properly checks for it. A rough outline of the XStream class @XStreamAlias("thing") public class Thing implements Serializable { private int id; private int someField; public int getId(){ ... } public int someField() { ... } } So now if I update that class to be: @XStreamAlias("thing") public class Thing implements Serializable { private int id; private int someField; private String newField; public int getId(){ ... } public int getSomeField() { ... } public String getNewField(){ ... } } I would want my test to fail because the old tests are not calling getNewField(). The goal is to ensure that if new getters are added, that we have some way of ensuring that the tests check them. Ideally, this would be contained entirely in the test and not require modifying the underlying Thing class. Any ideas? Thanks for looking!

  • I need help with a SQL query. Fetching an entry, it's most recent revision and it's fields.

    - by Tigger ate my dad
    Hi there, I'm building a CMS for my own needs, and finished planning my database layout. Basically I am abstracting all possible data-models into "sections" and all entries into one table. The final layout is as follows: Database diagram: I have yet to be allowed to post images, so here is a link to a diagram of my database. Entries (section_entries) are children of their section (sections). I save all edits to the entries in a new revision (section_entries_revisions), and also track revisions on the sections (section_revisions), in order to match the values of a revision, to the fields of the section that existed when the entry-revision was made. The section-revisions can have a number of fields (section_revision_fields) that define the attributes of entries in the section. There is a many-to-many relationship between the fields (section_revision_fields) and the entry-revisions (section_entry_revisions), that stores the values of the attributes defined by the section revision. Feel free to ask questions if the diagram is confusing. Now, this is the most complex SQL I've ever worked with, and the task of fetching my data is a little daunting. Basically what i want help with, is fetching an entry, when the only known variables are; section_id, section_entry_id. The query should fetch the most recent revision of that entry, and the section_revision model corresponding to section_revision_id in the section_entry_revisions table. It should also fetch the values of the fields in the section-revision. I was hoping for a query result, where there would be as many rows as fields in the section. Each row would contain the information of the entry and the section, and then information for one of the fields (e.g. each row corresponding to a field and it's value). I tried to explain the best I could. Again, feel free to ask questions if my description somehow lacking. I hope someone is up for the challenge. Best regards. :-)

  • Update MySQl table onDrop?

    - by dougvt
    Hi all. I am writing a PHP/MySQL application (using CodeIgniter) that uses some jQuery functionality for dragging table rows. I have a table in which the user can drag rows to the desired order (kind of a queue for which I need to preserve the rank of each row). I've been trying to figure out how to (and whether I should) update the database each time the user drops a row, in order to simplify the UI and avoid a "Save" button. I have the jQuery working and can send a serialized list back to the server onDrop, but is it good design practice to run an update query this often? The table will usually have 30-40 rows max, but if the user drags row 1 far down the list, then potentially all the rows would need to be updated to update the rank field. I've been wondering whether to send a giant query to the server, to loop through the rows in PHP and update each row with its own Update query, to send a small serialized list to a stored procedure to let the server do all the work, or perhaps a better method I haven't considered. I've read that stored procedures in MySQL are not very efficient and use a separate process for each call. Any advice as to the right solution here? Thanks very much for your help!
