• how to compare two tables fields name with another value in mysql?

  - by I Like PHP

  I have two tables table_school school_open_time|school_close_time|school_day 8:00 AM | 9:00PM | Monday 10:00 AM | 7:00PM | Wednesday table_college college_open_time|college_close_time|college_day 10:00 AM | 8:00PM | Monday 10:00 AM | 9:00PM | Tuesday 10:00 AM | 5:00PM | Wednesday Now I want to select school_open_time school_close time, college_open_time and college_close_time according to today (means college_day=school_day=today), and also if there is no row for a specific day in any of one table then it display blank field ( LEFT JOIN , I think I can use). Please suggest me best and optimized query for this. UPDATE: if there is no open time and close time for school then college_open_time and college_close_time has to be returned( not to be filled in database,just return) as school_open_time and school_close_time. and there always must be college_open_time and college_close_time for a given day MORE UPDATE: i m using below query SELECT college_open_time,college_close_time ,school_open_time, school_close_time FROM tbl_college LEFT JOIN tbl_school ON school_owner_id=college_owner_id WHERE college_owner_id='".$_session['user_id']."' AND college_day='".date('l',time())."'"; it return single row (left hand having some value and right hand having blank value) when there is no row of a given day in table_school, BUT display seven rows with same value on left hand side(college_open_time, college_close_time) and 6 blank row on right hand side (school_open_time and school_close_time) i need only one row when both table have a row of a given day but using above query take only first row of corresponding table_school where school_owner_id is 50(let), it not see the condition that school_day name should be given day

• MATLAB, time match filter

  - by Paul

  OK, I am still getting the hang of MATLAB. I have two files in different format. One Excel file. data1.xls, size= 86400 X 62. It looks like: Date/Time par1 par2 par3 par4 par5 par6 par6 par7 par8 par9 08/02/09 00:06:45 0 3 27 9.9 -133.2 0 0 0 1 0 Another file, data2.csv, size = 144 X 27. (If nothing is missing.) It looks like: date time P01 P02 P03 P04 P05 P06 P07 P08 P09 P10 P11 8/16/2009 0:00 51 45 46 54 53 52 524 5 399 89 78 Now I am using Data10minAvg = mean(reshape(Data,300,144,62)); to get the 10 min average of the first Excel file. Now I need to match up that file I am making above with the .csv file. The problem is many timestamps are missing in the .csv file. How do I make data2.csv into a file of size 144 X 27, replacing the missing datestamps by rows of zero? It will really help me than compare data1.xls file with newdata2.csv.

• MDX: Filtering a member set by a measure's table values

  - by oyvinro

  I have some numbers in a fact table, and have generated a measure which use the SUM aggregator to summarize the numbers. But the problem is that I only want to sum the numbers that are higher than, say 10. I tried using a generic expression in the measure definition, and that works of course, but the problem is that I need to be able to dynamically set that value, because it's not always 10, meaning users should be able to select it themselves. More specifically, my current MDX looks like this: WITH SET [Email Measures] AS '{[Measures].[Number Of Answered Cases], [Measures].[Max Expedition Time First In Case], [Measures].[Avg Expedition Times First In Case], [Measures].[Number Of Incoming Email Requests], [Measures].[Avg Number Of Emails In Cases], [Measures].[Avg Expedition Times Total],[Measures].[Number Of Answered Incoming Emails]}' SET [Organizations] AS '{[Organization.Id].[860]}' SET [Operators] AS '{[Operator.Id].[3379],[Operator.Id].[3181]}' SET [Email Accounts] AS '{[Email Account.Id].[6]}' MEMBER [Time.Date].[Date Period] AS Aggregate ({[Time.Date].[2008].[11].[11] :[Time.Date].[2009].[1].[2] }) MEMBER [Email.Type].[Email Types] AS Aggregate ({[Email.Type].[0]}) SELECT {[Email Measures]} ON columns, [Operators] ON rows FROM [Email_Fact] WHERE ( [Time.Date].[Date Period] ) Now, the member in question is the calculated member [Avg Expedition Times Total]. This member takes in two measures; [Sum Expedition Times] and [Nr of Expedition Times] and splits one on the other to get the average, all this presently works. However, I want [Sum Expedition Times] to only summarize values over or under a parameter of my/the user's wish. How do I filter the numbers [Sum Expedition Times] iterates through, rather than filtering on the sum that the measure gives me in the end?

• a potentially dangerous request.form value was detected but validateinput(false) not working

  - by tonybolding

  I have installed VS2010 and MVC2 and testing a simple form using tinyMCE. When I post the contents of the textarea in tinyMCE I get the dreaded YSD and the message "a potentially dangerous....." No problem I thought - seen this before so I put the ValidateInput(false) on the controller but no joy - I still get the error. page code in edit.aspx is: <% using (Html.BeginForm()){ % <!-- Gets replaced with TinyMCE, remember HTML in a textarea should be encoded --> <textarea id="elm1" name="mceText" rows="15" cols="80" style="width: 80%"> &lt;p&gt; This is some example text that you can edit inside the &lt;strong&gt;TinyMCE editor&lt;/strong&gt;. </textarea> <br /> <input type="submit" name="save" value="Submit" /> <input type="reset" name="reset" value="Reset" /> <%} % and Controller action is: [AcceptVerbs(HttpVerbs.Post)] [ValidateInput(false)] public ActionResult Edit(string mceText) { return View(); } Any thoughts - (I know the code is not complete) been trying this for hours but everyone just says to use ValidateInput(false)

• SQL Server insert performance with and without primary key

  - by Eric

  Summary: I have a table populated via the following: insert into the_table (...) select ... from some_other_table Running the above query with no primary key on the_table is ~15x faster than running it with a primary key, and I don't understand why. The details: I think this is best explained through code examples. I have a table: create table the_table ( a int not null, b smallint not null, c tinyint not null ); If I add a primary key, this insert query is terribly slow: alter table the_table add constraint PK_the_table primary key(a, b); -- Inserting ~880,000 rows insert into the_table (a,b,c) select a,b,c from some_view; Without the primary key, the same insert query is about 15x faster. However, after populating the_table without a primary key, I can add the primary key constraint and that only takes a few seconds. This one really makes no sense to me. More info: The estimated execution plan shows 0% total query time spent on the clustered index insert SQL Server 2008 R2 Developer edition, 10.50.1600 Any ideas?

  - by user338322

  I am trying to use a custom cell, My custom cell is of size 320*220 pixels. My table size is 320* by 1500 which is large enough I have set custom cell's view in scale to fill mode. But when i fill the table using custom cell all i see is first row. i have total four rows to be filld in a custom way. but they gets overlapped and i can not see any of the table.. They do look, but overlapped, Any hints .. about why its happening Do i need to make changes into nib? -(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{ static NSString *CellIdentifier = @"CustomCell"; CustomCell *cell = (CustomCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"CustomCell" owner:self options:nil]; for (id oneObject in nib) if ([oneObject isKindOfClass:[CustomCell class]]) cell = (CustomCell *)oneObject; } cell.iconImage.image = [UIImage imageNamed:[NSString stringWithFormat:@"beach%d.jpg",indexPath.row+1]]; cell.title.text=[[RArrray objectAtIndex:indexPath.row] objectForKey:@"Beach"]; return cell; }

• MySQL Query - WHERE and IF?

  - by Prash

  I'm not quite sure how to right this query. Basically, I'm going to have a table with two columns (OS and country_code) - more columns too, but those are the conditional ones. These will be either set to 0 for all, or specific ones, separated by commas. Now, what I'm trying achieve is pull data from the table if the OS and country_code = 0, or if they contain matching data (separated by commas). Then, I have a column for time. I want to select rows where the time is GREATER than the time column, unless the column time_t is set to false, in which case this shouldn't matter. I hope I explained it right? This is what I kind of have so far: $get = $db->prepare("SELECT * FROM commands WHERE country_code = 0 OR country_code LIKE :country_code AND OS = 0 OR OS LIKE :OS AND IF (time_t = 1, expiry > NOW()) "); $get->execute(array( ':country_code' => "%{$data['country_code']}%", ':OS' => "%{$data['OS']}%" ));

• How do I prevent my table cell's textview from being editable after editing is done?

  - by Gorgando

  So this is an interesting problem. I have custom tableviewcells that include a text field. When In my cellForRowAtIndexPath I have an if statement that determines whether or not the cell's text field should be editable- it looks like this: (self.isEditing) ? [infoCell.textField setEnabled:YES] : [infoCell.textField setEnabled:NO]; This actually works well - except for the issue I'm having. It makes it so that when the tableview is displayed, the rows' text field cannot be edited. When the user clicks "Edit" to put it into editing mode, then the text fields are enabled for editing. The Problem: When I am editing a field, and click "Done", it goes back to the regular tableview but the keyboard stays visible and the last cell's text field I was editing continues to be editable. What Should happen: The keyboard should go away and all the cells' text fields should no longer be editable. Any ideas about what could be going wrong? Things to look for? Thanks!

• Excel: Automating the Selection of an Unknown Number of Cells

  - by user1905080

  I’m trying to automate the formatting of an excel file by a macro and am seeking a solution. I have two columns titled Last Name and First Name which I would like to concatenate into a separate column titled Last Name, First Name. This is simple enough when done by hand: create one cell which does this, then drag that cell to include all cells within the range. The problem appears when trying to automate this. Because I can’t know the number of names that need to be concatenated ahead of time, I can’t automate the selection of cells by dragging. Can you help me automate this? I’ve tried a process of copying the initial concatenated cell, highlighting the column, and then pasting. I’ve also tried to use a formula which returned the concatenation only if there is text in the “Last Name” and “First Name” columns. However, in both cases, I end up with some 100,000 rows, putting a serious cramp on my ability to manipulate the worksheet. The best solution I can think of is to create concatenations within a fixed range of cells. Although this would create useless cells, at least there wouldn’t be 99,900 of them.

• Batch Inserts And Prepared Query Error

  - by ircmaxell

  Ok, so I need to populate a MS Access database table with results from a MySQL query. That's not hard at all. I've got the program written to where it copies a template .mdb file to a temp name and opens it via odbc. No problem so far. I've noticed that Access does not support batch inserting (VALUES (foo, bar), (second, query), (third query)). So that means I need to execute one query per row (there are potentially hundreds of thousands of rows). Initial performance tests show a rate of around 900 inserts/sec into Access. With our largest data sets, that could mean execution times of minutes (Which isn't the end of the world, but obviously the faster the better). So, I tried testing a prepared statement. But I keep getting an error (Warning: odbc_execute() [function.odbc-execute]: SQL error: [Microsoft][ODBC Microsoft Access Driver]COUNT field incorrect , SQL state 07001 in SQLExecute in D:\....php on line 30). Here's the code I'm using (Line 30 is odbc_execute): $sql = 'INSERT INTO table ([field0], [field1], [field2], [field3], [field4], [field5]) VALUES (?, ?, ?, ?, ?, ?)'; $stmt = odbc_prepare($conn, $sql); for ($i = 200001; $i < 300001; $i++) { $a = array($i, "Field1 $", "Field2 $i", "Field3 $i", "Field4 $i", $i); odbc_execute($stmt, $a); } So my question is two fold. First, is there any idea on why I'm getting that error (I've checked, and the number in the array matches the field list which matches the number of parameter ? markers)? And second, should I even bother with this or just use the straight INSERT statements? Like I said, time isn't critical, but if it's possible, I'd like to get that time as low as possible (Then again, I may be limited by disk throughput, since 900 operations/sec is high already)... Thanks

• Use where clause with Like in codeigniter

• Parsing a Multi-Index Excel File in Pandas

  - by rhaskett

  I have a time series excel file with a tri-level column MultiIndex that I would like to successfully parse if possible. There are some results on how to do this for an index on stack overflow but not the columns and the parse function has a header that does not seem to take a list of rows. The ExcelFile looks like is like the following: Column A is all the time series dates starting on A4 Column B has top_level1 (B1) mid_level1 (B2) low_level1 (B3) data (B4-B100+) Column C has null (C1) null (C2) low_level2 (C3) data (C4-C100+) Column D has null (D1) mid_level2 (D2) low_level1 (D3) data (D4-D100+) Column E has null (E1) null (E2) low_level2 (E3) data (E4-E100+) ... So there are two low_level values many mid_level values and a few top_level values but the trick is the top and mid level values are null and are assumed to be the values to the left. So, for instance all the columns above would have top_level1 as the top multi-index value. My best idea so far is to use transpose, but the it fills Unnamed: # everywhere and doesn't seem to work. In Pandas 0.13 read_csv seems to have a header parameter that can take a list, but this doesn't seem to work with parse.

• How do I manipulate the format on a DataGridView that is bound to a Data Source?

  - by Jack Johnstone

  I´m using SQL Server 2005 and Visual Studio 2008, C#. In the data source (the SQL Server data table) I use the DateTime format mm/dd/yyyy, however, in a forms overview (DataGridView) users would like to see a completely other format, with year, week number and day number of week (yyww,d) which is in string format. I´ve created an algorithm for the transformation between values (date to weekday), but can I populate the affected cells with yyww,d (string) instead of mm/dd/yyyy (DateTime)? This is what I´ve been testing out, without success (and note, it´s on the last line the problem becomes obvious, as the cell value won´t accept a string on runtime - it still wants to be a DateTime...) private void DataGridViewQueryFindRequests_CellFormatting( object sender, DataGridViewCellFormattingEventArgs e) { string weekAndDay = ""; DataGridViewCell cell = DataGridViewQueryFindRequests.Rows[e.RowIndex].Cells[e.ColumnIndex]; if (cell.ColumnIndex == 13 && cell.Value == null) mEmptyRow = true; if ((cell.ColumnIndex == 14 || cell.ColumnIndex == 15) && !mEmptyRow) { weekAndDay = ClassWeeksAndDates.dateToWeekNumber(Convert.ToDateTime(cell.Value)); cell.ValueType = typeof(string); cell.Value = weekAndDay; } }

• Scalable way to store files on server (PHP)?

  - by Nathaniel Bennett

  I'm creating my first web application - a really simplistic online text editor. What I need to do is find the best way to store text based files - a lot of them. These text files can be past 10,000 words in size (text words not computer words.) in essence I want the text documents to be limitless in size. I was thinking about storing the text files in my MySQL database - but thought there was a better way. Instead I'm planing on storing the text files in XML based format in a directory on my server. The rows in the database define the name of the xml based text file and the user who created the text along with basic metadata. An ID is generated using a V4 GUID generator , which gives the text an id and stores the text in the "/store" directory on my server. The text definitions in my server contain this id, and the android app I'm developing gets the contents of the text file by retrieving the text definition and then downloading the text to the local device using the GUID in the text definition. I just think this is a botch job? how can I improve this system? There has been cases of GUID colliding. I don't want this to happen. A "slim" possibility isn't good enough - I need to make sure there is absolutely no chance in a GUID collision. I was planning on checking the database for texts that have the same id before storing the text with a particular id - I however believe with over 20,000 pieces of text in my database this would take an long time and produce unneeded stress on the server. How can I make GUID safe? What happens when a GUID collides? The server backend is going to be written in PHP.

• saving mySql row checkpoint in table ?

  - by Keet

  hello, I am having a wee problem, and I am sure there is a more convenient/simpler way to achieve the solution, but all searches are throw in up a blanks at the moment ! I have a mysql db that is regularly updated by php page [ via a cron job ] this adds or deletes entries as appropriate. My issue is that I also need to check if any details [ie the phone number or similar] for the entry have changed, but doing this at every call is not possible [ not only does is seem to me to be overkill, but I am restricted by a 3rd party api call limit] Plus this is not critical info. So I was thinking it might be best to just check one entry per page call, and iterate through the rows/entires with each successive page call. What would be the best way of doing this, ie keeping track of which entry/row in the table that the should be checked next? I have 2 ideas of how to implement this: 1 ) The id of current row could be save to a file on the server [ surely not the best way] 2) an extra boolean field [check] is add to the table, set to True on the first entry and false to all other. Then on each page call it; finds 'where check = TRUE' runs the update check on this row, 'set check = FALSE' 'set [the next row] check = TRUE' Si this the best way to do this, or does anyone have any better sugestion ? thanks in advance ! .k PS sorry about the title

• Union and order by

  - by David Lively

  Consider a table like tbl_ranks -------------------------------- family_id | item_id | view_count -------------------------------- 1 10 101 1 11 112 1 13 109 2 21 101 2 22 112 2 23 109 3 30 101 3 31 112 3 33 109 4 40 101 4 51 112 4 63 109 5 80 101 5 81 112 5 88 109 I need to generate a result set with the top two(2) rows for a subset of family ids (say, 1,2,3 and 4) ordered by view count. I'd like to do something like select top 2 * from tbl_ranks where family_id = 1 order by view_count union all select top 2 * from tbl_ranks where family_id = 2 order by view_count union all select top 2 * from tbl_ranks where family_id = 3 order by view_count union all select top 2 * from tbl_ranks where family_id = 4 order by view_count but, of course, order by isn't valid in a union all context in this manner. Any suggestions? I know I could run a set of 4 queries, store the results into a temp table and select the contents of that temp as the final result, but I'd rather avoid using a temp table if possible. Note: in the real app, the number of records per family id is indeterminate, and the view_counts are also not fixed as they appear in the above example.

• Aggregate SQL column values by time period

  - by user305688

  I have some numerical data that comes in every 5 minutes (i.e. 288 values per day, and quite a few days worth of data). I need to write a query that can return the sums of all values for each day. So currently the table looks like this: 03/30/2010 00:01:00 -- 553 03/30/2010 00:06:00 -- 558 03/30/2010 00:11:00 -- 565 03/30/2010 00:16:00 -- 565 03/30/2010 00:21:00 -- 558 03/30/2010 00:26:00 -- 566 03/30/2010 00:31:00 -- 553 ... And this goes on for 'x' number of days, I'd like the query to return 'x' number of rows, each of which containing the sum of all the values on each day. Something like this: 03/30/2010 -- <sum> 03/31/2010 -- <sum> 04/01/2010 -- <sum> The query will go inside a Dundas webpart, so unfortunately I can't write custom user functions to assist it. All the logic needs to be in just the one big query. Any help would be appreciated, thanks. I'm trying to get it to work using GROUP BY and DATEPART at the moment, not sure if it's the right way to go about it.

• NSMagedObjectContext, threads and NSFechedResultsController

  - by tmpz

  Dear iphone developers, Core Data newbie speaking here. In my application I have two NSManagedObjectContext that refer to that same NSPersistentStorageController. One ManagedObjectContext (c1) is in the main thread --created when I create a NSFetchedResultsController -- and the second ManagedObjectContext (c2) created in a second thread, running in the background, detached from the main thread. In the background thread I pull some data off a website and insert the entities created for the pulled data in the thread's ManagedObjectContext (c2). In the meanwhile, the main thread sits doing nothing and displaying a UITableView whose data do be display should be provided by the NSFetchedResultsController. When the background thread has finished pulling the data and inserting entities in c2, c2 saves, and the background thread notifies the main thread that the processing has finished before it exiting. As a matter of fact, the entities that I have inserted in c2 are know by c1 because it can ask it about one particular entity with [c1 existingObjectWithID:ObjectID error:&error]; I would expect at this point, if I call on my tableview reloadData to see some rows showing up with the data I pulled from the web in the background thread thanks to the NSFetchedResults controller which should react to the modifications of its ManagedObjectContext (c1). But nothing is happening! Only if I restart the application I see what I have previously pulled from the web! Where am I doing things wrong? Thank you in advance!

• SQL query select from table and group on other column...

  - by scaryjones

  I'm phrasing the question title poorly as I'm not sure what to call what I'm trying to do but it really should be simple. I've a link / join table with two ID columns. I want to run a check before saving new rows to the table. The user can save attributes through a webpage but I need to check that the same combination doesn't exist before saving it. With one record it's easy as obviously you just check if that attributeId is already in the table, if it is don't allow them to save it again. However, if the user chooses a combination of that attribute and another one then they should be allowed to save it. Here's an image of what I mean: So if a user now tried to save an attribute with ID of 1 it will stop them, but I need it to also stop them if they tried ID's of 1, 10 so long as both 1 and 10 had the same productAttributeId. I'm confusing this in my explanation but I'm hoping the image will clarify what I need to do. This should be simple so I presume I'm missing something.

• Is it possible to get multiple forms to work with one ajax post function

  - by Scarface

  Hey guys I have a system where there is one form for each friend you have and I used to have an ajax post function for each form, but I want to save code and was wondering if it was possible to get multiple forms to work with just one post function. If anyone has any advice on how to achieve this I would appreciate it. For example <div id="message"> <form id='submit' class='message-form' method='POST' > <input type='hidden' id='to' value='friend1' maxlength='255' > Subject<br><input type='text' id='subject' maxlength='50'><br> Message<br><textarea id='message2' cols='50' rows='15'></textarea> <input type='submit' id='submitmessage' class='responsebutton' value='Send'> </form> </div> $(document).ready(function(){ $(".message-form").submit(function() { $("#submitmessage").attr({ disabled:true, value:\"Sending...\" }); var to = $('#to').attr('value'); var subject = $('#subject').attr('value'); var message = $('#message2').attr('value'); $.ajax({ type: "POST", url: "messageprocess.php", data: 'to='+ to + '&subject=' + subject + '&message=' + message, success: function(response) { if(response == "OK") { $('.message-form').html("<div id='message'></div>"); $('#message').html("<h2>Email has been sent!</h2>") .append("<p>Please wait...</p>") .hide() .fadeIn(1500, function() { $('#message').append(\"<img id='checkmark' src='images/check.png' />\"); });

• initialize jquery slider with hidden input value from database.

  - by ludwigs3rd

  I'm using a slider as user input for a screen. Basically it's a bulk update screen where there is a table with multiple rows, thus multiple sliders. I created it so that the hidden value is what gets posted in the form. <td> <input class="percentageProvidedHidden" type="hidden" name='<%= "Values[" + i + "].Percentage" %>' value='<%=item.Percentage %>' /> <div class="percentageProvidedSlider"></div> </td> I have the update working just fine (move slider changes hidden input value, submit, values are updated in db), however, I can't get the damn thing to initialize with the value of the hidden input (note the "value: " parameter below). In this case I think $(this) isn't actually $('percentageProvidedSlider') but the page itself. Can someone help me get the slider value to initialize with the hidden input field? I'm using ASP .Net MVC 2 so if there are any methods I should try with that I welcome them as well. $('.percentageProvidedSlider').slider( { min: 0, max: 100, step: 25, value: $(this).parents('tr').find('input.percentageProvidedHidden').val(), slide: function(e, ui) { var mypos = ui.value; $(this).find('.ui-slider-handle').text(ui.value); }, change: function(event, ui) { var myVal = $(this).slider("option", "value"); $(this).parents('tr').find('input.percentageProvidedHidden').val(myVal); var myDropDown = $(this).parents('tr').find('select.verified'); } });
