• MySQL - Conflicting WHERE and GROUP BY Statements

  - by TaylorPLM

  I have a query returning the counts of some data, but I do NOT want data that has a null value in it... As an example, the code rolls stats from a clicking system into a table. SELECT sh.dropid, ... FROM subscriberhistory sh INNER JOIN subscriberhistory sh2 on sh.subid = sh2.subid WHERE sh.dropid IS NOT NULL AND sh.dropid != "" ... GROUP BY sh.dropid An example of the record set returned would look like this... 400 2 3 4 5 6 401 2 3 6 5 4 NULL 2 3 4 5 1 There are some other where clauses, and a few more selects (as I said, using the count aggregate) that are also within the query. There is also an order by statement. Again, the goal is to keep the NULL data out of the preceding record set. Could someone explain to me why this behavior is occurring and what to do to solve it.

• Offline Database Write Cache in C#

  - by Todd Gardner

  I have a windows service that receives a large amount of data that needs to be transformed and persisted to a database. To ensure that we do not lose data, I want to create a "Write cache" for the data that will continue regardless if the database is online. Once the database becomes available again, I would want it to flush the content of the cache back into the database. I've seen some articles indicating that I might be able to do this with NHibernate, but I haven't found it conclusively. What options exist for this, and is NHibernate the appropriate direction?

• How do I clear the text contents of a div in javascript?

  - by Ben

  I'm temporarily adding contents to a div,tempDiv, and adding that to a link which is appended to a div, #contentHere, that's displayed. I need to clear the contents of tempDiv so that the links aren't appended to each other, creating a string of urls that don't link to anywhere. $(document).ready(function(){ $.getJSON("data.php", function(data){ for(i = 0; i < 5; i++){ $("#tempDiv").append(data.justIn[i].dataLink+ ' '); $("#contentHere").append("<a href=\"#tempDiv\">Click to go to the div link</a>"); //I need to clear the contents of tempDiv here } }); }); Solutions to clearing the temporary contents of the div as I go?

• How do I set properties related to the calling method's scope?

  - by Thiado de Arruda

  I'm not looking for a way to associate values with a thread using the 'SetData' method. I need to store some kind of data that will only exist during the scope of a calling method, could be the immediate parent or any other call that is made down on the stack. For example: void SomeMethod() { string someInfo = "someInfo"; SomeOtherMethod(); object data = GetDataOnCurrentScope("someKey"); } void SomeOtherMethod() { SetDataOnParentScope("someKey", somevalue); } In this case both the 'someInfo' local variable and the data set with the "someKey" key will disapear after 'SomeMethod' returns. Is something like this possible? This may go against the rules of a stack, but who knows if someone has an idea...

• Running javascript in AJAX loaded DIV

  - by WiseDonkey

  I have page loading, via AJAX a PHP page into a div. In turn, this loaded page has it's own javascript and AJAX loaded div. Reason is to allow user to select data alter data within loaded data. I'm trying to do this without the help of JSON or such to communicate between JS and PHP. I'm guessing the parent calling page has already loaded the javascript, and the AJAX loaded content can't access that? (I've tried running the JS into the AJAX loaded content as well) If so, is there anyway to access that?

• Fortran - String with unknown characters into substrings

  - by Masoud

  I am trying to put an input string into sub-string arrays. The number of data in the input file are less than 10 but unknown. The number of spaces between each data is also unclear. Example: Asd B Cwqe21 Ddsw Eww I am quite novice to Fortran, so I do not know which format I should use. My problem is that I do not know the number of data (here I assumed that there are 5), so how can I make the code work? I tried the following which did not work: CHARACTER (LEN=100), DIMENSION(10) :: string READ (1,*) (string,I=1,10) It seems that the error I got was because there was no 6th string to read and put into string(6). I tried using the "Index" to find the space, but since I do not know how many spaces are in the string, it did not help me.

• WPF input datagrid?

  - by SAD

  I would like to create an input DataGrid - an empty set of rows with the column headers that can be filled with data by a user and then saved to a database. The DataGrid will not be therefore used to display data but acts like an input field. The behaviour would be similar to the one of Excell. The problem is that if the DataGrid has no data provided for it, it is not visible in the application and the user cannot enter anything. Is the DataGrid a good choice? How can this sort of functionality be implemented with a different control? I would prefer to use the DataGrid tough. Thanks a lot for any help on this.

• SQL use comma-separated values with IN clause

  - by user342944

  I am developing an ASP.NET application and passing a string value like "1,2,3,4" into a procedure to select those values which are IN (1,2,3,4) but its saying "Conversion failed when converting the varchar value '1,2,3,4' to data type int." Here is the aspx code: private void fillRoles() { /*Read in User Profile Data from database */ Database db = DatabaseFactory.CreateDatabase(); DbCommand cmd = db.GetStoredProcCommand("sp_getUserRoles"); db.AddInParameter(cmd, "@pGroupIDs", System.Data.DbType.String); db.SetParameterValue(cmd, "@pGroupIDs", "1,2,3,4"); IDataReader reader = db.ExecuteReader(cmd); DropDownListRole.DataTextField = "Group"; DropDownListRole.DataValueField = "ID"; while (reader.Read()) { DropDownListRole.Items.Add((new ListItem(reader[1].ToString(), reader[0].ToString()))); } reader.Close(); } Here is my procedure: CREATE Procedure [dbo].[sp_getUserRoles](@pGroupIDs varchar(50)) AS BEGIN SELECT * FROM CheckList_Groups Where id in (@pGroupIDs) END

• ASP.NET: How to "reset" validation after calling Page_ClientValidate

  - by Josh Young

  I have an ASP.NET page with a jQuery dialog that is displayed to change some data. I am setting up the jQuery dialog so that when the user clicks the OK button it calls ASP.NET's Page_ClientValidate('validationGroup') via javascript, finds all the invalid controls and changes their CSS class. So here's the scenario: the user opens the dialog, keys in some invalid data, clicks OK (receiving the validation messages), and then clicks Cancel. Now the dialog is closed, but the validation messages are still there, so that when they open the dialog again, the data goes back to the way it was initially, but the form is still in the invalid state (the validation messages are still displaying). What I need is a "reset" function of sorts to call after calling Page_ClientValidate('validationGroup'). Does this exist?

• MS Access caching of reports / query results

  - by FrustratedWithFormsDesigner

  Is it possible to cache a query or report the first time it is run? It seems that opening a report will re-query the datasource. For certain queries, the data source does not change frequently enough that I'd be worried about a cache being out of date (users are notified when the database changes), and it would be much easier for the users to be able to open the report instantly rather than having to wait several minutes every time they want to see the data (though I realize if they close the file the caches will be lost - that's OK). Data comes from an ODBC connection to Oracle, using Access 2003.

• otal Number of records required in paged grid

  - by sumitchauhan

  I am using a data grid and has bound a data source with it. I am trying to get the total number of records in the grid in overriden InitializePager method from pagedDataSource DataSourceCount. I thought DataSourceCount returns number of records from SelectCountMethod of ObjectDataSource. But DataSourceCount is giving me the page size and not the total number of records, whereas when I debug and see in SelectCountMethod it is returning correct number of total Records. I am not sure how to get the data from SelectCountMethod in DataGrid.

  - by KA100

  What I'm looking for is something like materialized views in front-end that shows my data in diffident ways without full recalculation. let's say I have stock watcher with many front-end views and dashborads some based on aggregation, order by or just filter with different criteria defined realtime by user.

• How to use SynonymFilterFactory in Solr?

  - by AlxVallejo

  I'm trying to execute synonym filtering at query time so that if I search for X, results for Y also show up. I go to where Solr is being run, edit the .txt file and add X, Y on a new line. This does not work. I check the schema and I see: <analyzer type="query"> <filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt" ignoreCase="true" expand="true" /> What am I missing? EDIT Assessing configuration files tomcat6/Catalina/localhost seems to point to the correct location <Context docBase="/data/solr/solr.war" debug="0" privileged="true" allowLinking="true" crossContext="true"> <Environment name="solr/home" type="java.lang.String" value="/data/solr" override="true" /> </Context> Also, in the Solr admin I see this. What does cwd mean? cwd=/usr/share/tomcat6 SolrHome=/data/solr/

• Exporting ActiveRecord objects into POROs

  - by Lucas d. Prim

  Hello, I'm developing a "script generator" to automatize some processes at work. It has a Rails application running on a server that stores all data needed to make the script and generates the script itself at the end of the process. The problem I am having is how to export the data from the ActiveRecord format to Plain Old Ruby Objects (POROs) so I can deal with them in my script with no database support and a pure-ruby implementation. I tought about YAML, CSV or something like this to export the data but it would be a painful process to update these structures if the process changes. Is there a simpler way? Ty!

  I am trying to understand the purpose of addListener in node.js. Can someone explain please? Thanks! A simple example would be: var tcp = require('tcp'); var server = tcp.createServer(function (socket) { socket.setEncoding("utf8"); socket.addListener("connect", function () { socket.write("hello\r\n"); }); socket.addListener("data", function (data) { socket.write(data); }); socket.addListener("end", function () { socket.write("goodbye\r\n"); socket.end(); }); }); server.listen(7000, "localhost");

• How to write back to database from Silverlight?

  - by Manoj

  Hi, I use LINQ to SQL to get data from a database and use a service contract to access it in Silverlight at the client side. I display the data in a DataGrid. Now how do I make sure that any changes in the datagrid is written back to the database? EDIT: This is the example code I implemented: http://www.silverlight.net/learn/tutorials/sqldatagrid-cs/ Here I wanted any change in the datagrid reflected back in the database. The SubmitChanges function works in the DataContext object which is: public partial class DataClasses1DataContext : System.Data.Linq.DataContext But this is not exposed in the contract and so not visible in the client side code.

• How should I deal with sqlite errors?

  - by Dustin

  I have a long running application written in a mix of C and C++ that stores data in sqlite. While I am confident that committed data will remain available (barring mechanical failure) and uncommitted data will not be, it's not clear to me what I can do with this sort of middle state. I do a large number of inserts in a transaction and then commit it. When an error occurs on a given statement, I can schedule it to be attempted at some point in the future. It sounds like some errors might implicitly rollback my transaction (which would be undesirable if true). A larger problem is what happens when my commit itself fails. Currently, I'm just going to continue to retry it until it works. I would expect that whatever would cause my commit to fail may very well also cause a rollback to fail. What is the recommended mechanism for error handling in such a situation?

• send datas to php with ajax - Internal Server Error(500)

  i try to send my datas to php with ajax but there's strange mistake. this is my ajax script, function deleteData2() { var artistIds = new Array(); $(".p16 input:checked").each(function(){ artistIds.push($(this).attr('id')); }); $.post('/json/crewonly/deleteDataAjax2', { json: JSON.stringify({'artistIds': artistIds}) }, function(response){ alert(response); }); } i think this works correctly but in php side, i face 500 internal server error(500). public function deleteDataAjax2() { $json = $_POST['json']; $data = json_decode($json); $artistIds = $data['artistIds']; $this->sendJSONResponse($artistIds); } Above code is my php. For example, when i try to send $data to ajax, i print my ids in json mode: However, when i try to send $artistIds to ajax side, i gives 500 error why?
