  • Php PEAR, Database Abstraction & Factory Methods

    - by pws5068
    I'm interested in learning more about design practices in PHP for Database Abstraction & Factory methods. For background, my site is a special-interest social networking community currently in beta mode. Currently, I've started moving my old code for object retrieval to factory methods. However, I do feel like I'm limiting myself by keeping a lot of SQL table names and structure separated in each function/method. Questions: 1.) Is there a reason to use PEAR (or similar) if I dont anticipate switching databases? 2.) Can PEAR interface with the MySqli prepared statements I currently use? 3.) Will it help me separate table names from each method? (If no, what other design patterns might I want to research?) 4.) Will it slow down my site once I have a significantly large member base?

  • SQL: Find difference between dates with grouping

    - by ajbeaven
    I have a problem that seems similar to this fellow - I just want to display the data slightly differently. I'm pretty terrible with SQL so can't modify it to suit, but perhaps someone else can. My table looks similar to this (date format is dd/mm/yyyy): ID User Date_start Role 1 Andy 01/04/2010 A 2 Andy 10/04/2010 B 3 Andy 20/04/2010 A 4 John 02/05/2010 A I want to show the total number of days that anyone was in a certain role. Users stay in the role until there is another entry into the table. Users can only be in one role at a time. So the summary data would look like this (assuming that the date is 04/05/2010): A: 26 days B: 10 days Thanks for any help :)

  • getting mysql_insert_id() while using ON DUPLICATE KEY UPDATE with PHP

    - by julio
    Hi-- I've found a few answers for this using mySQL alone, but I was hoping someone could show me a way to get the ID of the last inserted or updated row of a mysql DB when using PHP to handle the inserts/updates. Currently I have something like this, where column3 is a unique key, and there's also an id column that's an autoincremented primary key: $query ="INSERT INTO TABLE (column1, column2, column3) VALUES (value1, value2, value3) ON DUPLICATE KEY UPDATE SET column1=value1, column2=value2, column3=value3"; mysql_query($query); $my_id = mysql_insert_id(); $my_id is correct on INSERT, but incorrect when it's updating a row (ON DUPLICATE KEY UPDATE). I have seen several posts with people advising that you use something like INSERT INTO table (a) VALUES (0) ON DUPLICATE KEY UPDATE id=LAST_INSERT_ID(id) to get a valid ID value when the ON DUPLICATE KEY is invoked-- but will this return that valid ID to the PHP "mysql_insert_id()" function? Thanks for any advice.

  • Ordering recursive result set in SQL Server

    - by Ben
    I am having extreme difficulty constructing a query which returns an XML style hierarchy. We have a database table which contains a hierarchy of URLs for our website. The table contains the columns: ID, URL, DisplayName, ParentID, ItemOrder The parent ID forms a recursive relationship between the current item and it's parent. The item should site below it's parent in the hierarchy and it should also be ordered using the item order against items at the same level in the hierarchy. I have managed to get a recursive query working so it drills down the hierarchy sequentially but I cannot order this by the item order as well. My current query is below: WITH Parents AS ( SELECT MenuItemId, URL, ParentItemId, ItemOrder FROM CambsMenu UNION ALL SELECT si.MenuItemId, si.URL, si.ParentItemId, si.ItemOrder FROM CambsMenu si INNER JOIN Parents p ON si.ParentItemId = p.MenuItemId ) SELECT DISTINCT * FROM Parents

  • Force redraw as resizing NSTableColumn in NSTableView?

    - by Dov
    I've implemented - (CGFloat)tableView:(NSTableView *)tableView heightOfRow:(NSInteger)row in my NSTableView's delegate to resize the height of my table's rows as the width of the leftmost column changes. The problem is that only that column redraws during the resizing (and any column that slide into view during the resize). This results in the funky visual below after resizing. What I'd like is a way to tell the table view to completely redraw while the user is resizing a column. Right now the most I've been able to figure out is calling setNeedsDisplay after it that column finishes resizing.

  • Show/Hide button (text) for Accordion

    - by Kevin
    Have an accordion with a "view" button to open close the accordion panel (using jQuery Tools), but I would like to have dynamic text that says "show/hide" depending on the state... Here is the code for the accordion in asp.NET <div id="accordion"> <% foreach (var eventModel in ViewModel) { %> <% var isNewMonth = eventModel.Date.Month != previousMonth; %> <% if (isNewMonth && previousMonth > 0) { %></table></div><% } %> <% previousMonth = eventModel.Date.Month; %> <% if (isNewMonth) { %> <h2><%= string.Concat(eventModel.Date.ToString("MMMM"), " ", eventModel.Date.Year) %> <span style="float:right;"><a href="#" class="button blue small">View</a></span></h2> <div class="pane" style="display:block"> <table id="listTable" width="100%" cellpadding="3" cellspacing="0" border="0"> <tr align="left" valign="top"><th align="left" valign="top">Date</th><th align="left" valign="top">Event</th><th align="left" valign="top">Event Type</th></tr> <% } %> <tr align="left" valign="top"><td align="left" valign="top"><b><span id="date" style="float:left;"> <%= string.Concat(eventModel.Date.ToString("MMMM"), " ", eventModel.Date.Day, " </span><span id='day' style='float:left'>" + eventModel.Date.DayOfWeek + "</span> ")%></b></td><td align="left" valign="top" ><%= Html.ActionLink(eventModel.Name.Truncate(40), "event", "register", new { id = eventModel.Id }, null)%></td><td align="left" valign="top"><%= string.Concat(" ", eventModel.Sport)%></td></tr> <% } %> <% if (ViewModel.Count > 0) { %></table></div><% } %> </div> Here is the initialization script using jQuery: $(function() { $("#accordion").tabs("#accordion div.pane", {tabs: 'h2', effect: 'slide', initialIndex: 0}); $(".small").click(function() { moveToTop(); }); });

  • How can I build my SQL query from these tables?

    - by vee
    Hi All, I'm thinking of building query from these 2 tables (on SQL Server 2008). I have 2 tables as shown below: Table 1 MemberId . MemberName . Percentage . Amount1 00000001 AAA 1.0 100 00000002 BBB 1.2 800 00000003 ZZZ 1.0 700 Table 2 MemberId . MemberName . Percentage . Amount2 00000002 BBB 1.5 500 00000002 BBB 1.6 100 00000002 BBB 1.6 150 The result I want is MemberId . MemberName . Percentage . Amount . NettAmount 00000001 AAA 1.0 100 100 00000002 BBB 1.2 800 50 <-- 800-(500+100+150) 00000002 BBB 1.5 500 500 00000002 BBB 1.6 650 650 00000003 ZZZ 1.0 700 700 50 comes from 800 in Table1 minus sum of Amount2 in table2 for MemberID=00000002 Plz someone help me to build the query to reach this result. Thank you in advance.

  • Complicated football league Dynamic Ordering in MySQL?

    - by Dan
    I have a table 'games' for a football league as follows: date home_team_id away_team_id home_score away_score - 1 2 6 21 - 3 1 7 19 I can't figure out how to dynamically generate a list of team ID's ordered by Wins (then points for if poss)? -- I have this query which works fine when I have a $team_id but of cause then I can only do 1 team at a time, and that doesn't allow for ordering at query level ((SELECT COUNT(*) FROM `games` WHERE ((`home_score` > `away_score`) AND `home_team_id` = '.$team_id.')) + (SELECT COUNT(*) FROM `games` WHERE ((`home_score` < `away_score`) AND `away_team_id` = '.$team_id.'))) AS `wins` I wonder if i can use this with some form of GROUP, or mySQL can know the $team_id itself? I've also tried some multiple JOINs with the 'team' table but they didn't work either. Thanks, Dan

  • How to correctly calculate address spaces?

    - by user337308
    Below is an example of a question given on my last test in a Computer Engineering course. Anyone mind explaining to me how to get the start/end addresses of each? I have listed the correct answers at the bottom... The MSP430F2410 device has an address space of 64 KB (the basic MSP430 architecture). Fill in the table below if we know the following. The first 16 bytes of the address space (starting at the address 0x0000) is reserved for special function registers (IE1, IE2, IFG1, IFG2, etc.), the next 240 bytes is reserved for 8-bit peripheral devices, and the next 256 bytes is reserved for 16-bit peripheral devices. The RAM memory capacity is 2 Kbytes and it starts at the address 0x1100. At the top of the address space is 56KB of flash memory reserved for code and interrupt vector table. What Start Address End Address Special Function Registers (16 bytes) 0x0000 0x000F 8-bit peripheral devices (240 bytes) 0x0010 0x00FF 16-bit peripheral devices (256 bytes) 0x0100 0x01FF RAM memory (2 Kbytes) 0x1100 0x18FF Flash Memory (56 Kbytes) 0x2000 0xFFFF

  • NHibernate - is property lazy loading possible?

    - by Ben
    I've got some binary data that I store and was going to separate this out into a separate table so it could be lazy loaded. However, i then came across this post by Ayende (http://ayende.com/Blog/archive/2010/01/27/nhibernate-new-feature-lazy-properties.aspx) which suggests that property lazy loading is now possible. I have added the lazy="true" attribute to my property mapping but the field is still loaded from the database (I am using a simple text field to test). My query: return _session.CreateQuery("from Product") .SetMaxResults(1) .UniqueResult<Product>(); Mapping: <property name="Description" type="string" column="FullDescription" lazy="true"/> Has anyone been able to get this working? Personally I prefer this approach than having to add another table to my database.

  • In Oracle 10g, how do I see tables in schemes other than system

    - by Yasir Arsanukaev
    In the hr schema there's a table emloyees, I can query data from it specifying it implicitly SELECT count(*) FROM hr.employees while logged in as system, but when I navigate to Home-Object Browser in the browser I can't see the table employees and other tables in other schemas. Can I manage tables in schemas other than system while logged in as system? Maybe there's some setting which enables me to group tables by schema. My Oracle Database version is 10.2.0.1 Express Edition. IIRC I could see all tables in Oracle Database 10.1.x.y. Thanks.

  • Future proof Primary Key design in postgresql

    - by John P
    I've always used either auto_generated or Sequences in the past for my primary keys. With the current system I'm working on there is the possibility of having to eventually partition the data which has never been a requirement in the past. Knowing that I may need to partition the data in the future, is there any advantage of using UUIDs for PKs instead of the database's built-in sequences? If so, is there a design pattern that can safely generate relatively short keys (say 6 characters instead of the usual long one e6709870-5cbc-11df-a08a-0800200c9a66)? 36^6 keys per-table is more than sufficient for any table I could imagine. I will be using the keys in URLs so conciseness is important.

  • Will MyISAM type tables work better than InnoDB for large numbers of columns?

    - by Ethan
    I have a MySQL InnoDB table with 238 columns. 56 of them are TEXT type, 27 are VARCHAR(255). I am getting MySQL error 139 when users insert data sometimes. After research I found that I'm probably running into InnoDB row size/column size/column count limitations. (I'm putting it that way because the specific limits among those three things are interdependent.) Docs on InnoDB give an idea of the limits. If I switch this table to MyISAM is it likely to solve the problem? I understand the maximum row size of 65,535 bytes. I think I'm hitting InnoDB's additional 8000 byte limit somehow. Switching to PostgreSQL is also a remote option, but would take much longer.

  • Best practice. Do I save html tags in DB or store the html entity value?

    - by Matt
    Hi Guys, I was wondering about which way i should do the following. I am using the tiny MCE wysiwyg editor which formats the users data with the right html tags. Now, i need to save this data entered into the editor into a database table. Should I encode the html tags to their corresponding entities when inserting into the DB, then when i get the data back from the table, not have the encode it for XSS purposes but I'd still have to use eval for the html tags to format the text. OR Do i save the html tags into the database, then when i get the data back from the database encode the html tags to their entities, but then as the tags will appear to the user, I'd have to use the eval function to actually format the data as it was entered. My thoughts are with the first option, I just wondered on what you guys thought.

  • SQL CHECK constraint issues

    - by blahblah
    I'm using SQL Server 2008 and I have a table with three columns: Length, StartTime and EndTime. I want to make a CHECK constraint on this table which says that: if Length == NULL then StartTime <> NULL and EndTime <> NULL else StartTime == NULL and EndTime == NULL I've begun to try things like this: Length == NULL AND StartTime <> NULL AND EndTime <> NULL Obviously this is not enough, but even this simple expression will not validate. I get the error: "Error validating 'CK_Test_Length_Or_Time'. Do you want to edit the constraint?" Any ideas on how to go about doing this?

  • How can I edit a css rule in jQuery?

    - by chacham15
    The purpose is that rows are dynamically added to a table and it is not as nice (and slower) to apply the rule manually later. The specific example is that I am creating a tree table to represent a folder directory. Each folder is a div. In each div, there is a ul with an li for each columns' information. These li have a class name equivalent to the column name. This provides column width. I want to make the columns resizable however. I could do $('.className').css('width', newWidth) but then this wont apply to newly inserted items. Therefore, I want to modify the css rule. How do I do this?

  • Localized tables and Entity Framework

    - by Pyttroll
    Hi all, I have a scenario where I need to localized values of objects in my database. Let's say you have an application that can create animals, if the user is english the value of the "Name" property of an animal would be entered as "Cat" in the UI whereas it would be entered as "Chat" in french. The animal culture table would contain 2 records pointing to the same animal in the parent table. When reading values back, if the value of "Name" does not exist in the user culture the default value (value the object was originally created with) would be used. The following diagrams demonstrate how the data is stored in SQL: I'm trying to map this schema to an object model using the Entity Framework, I'm a bit confused as to what the best way to approach the problem. Is EF appropriate for this? Should I used EF4? This EF model will be used by .NET RIA Services. Thanks, Pierre-Yves Troel Ayuda Media Systems http://www.ayudasystems.com

  • Need to work out database structure

    - by jim smith
    Hi, Just need a little kickstart with this. I have Mysql/PHP, and I have 5,000 products. I have 30 companies I need to store some data for those 30 companies for each product as follows: a) prices b) stock qty I also need to store data historically on a daily basis. So the table... It makes sense that the records will be the products because there's 5000, and if I put the companies as the columns, I can store the prices, but what about the stock quantities? I could create two columns for each compoany, one for prices, one for qty. Then make the tablename the date for that day...so theer would be a new table for every day with 5000 products in it? is this the correct way? Some idea on how I'll be retreiving data the top 5 lowest prices (and the company) by product for a certain date the price and stock changes in the past 7 days by product

  • Compressing large text data before storing into db?

    - by Steel Plume
    Hello, I have application which retrieves many large log files from a system LAN. Currently I put all log files on Postgresql, the table has a column type TEXT and I don't plan any search on this text column because I use another external process which nightly retrieves all files and scans for sensitive pattern. So the column value could be also a BLOB or a CLOB, but now my question is the following, the database has already its compression system, but could I improve this compression manually like with common compressor utilities? And above all WHAT IF I manually pre-compress the large file and then I put as binary into the data table, is it unuseful as database system provides its internal compression?
