• Add page item to either Joomla, Drupal or Wordpress

  - by HP

  I just want to design this very simple website. Basically there are multiple pages A, B, C... and each page has item A1, A2.. or B1, B2... These items follow fixed HTML template (table,image) and only specific content fields (name, body text..) can be change in the back-end. Backend users can add new pages or new items each page. Does anyone know some plugin for either Joomla, Drupal or Wordpress that can do the simple purpose above? Thanks

• CakePHP hasAndBelongsToMany (HABTM) Delete Joining Record

  - by Jason McCreary

  I have a HABTM relationship between Users and Locations. Both Models have the appropriate $hasAndBelongsToMany variable set. When I managing User Locations, I want to delete the association between the User and Location, but not the Location. Clearly this Location could belong to other users. I would expect the following code to delete just the join table record provided the HABTM associations, but it deleted both records. $this->Weather->deleteAll(array('Weather.id' => $this->data['weather_ids'], false); However, I am new to CakePHP, so I am sure I am missing something. I have tried setting cascade to false and changing the Model order with User, User-Weather, Weather-User. No luck. Thanks in advance for any help.

• Hibernate Auto-Increment not working

  - by dharga

  I have a column in my DB that is set with Identity(1,1) and I can't get hibernate annotations to work for it. I get errors when I try to create a new record. In my entity I have the following. @GeneratedValue(strategy=GenerationType.IDENTITY, generator="native") @Column(name="SeqNo", unique=true, nullable=false) BigDecimal seqNo; But when I try to add a new record I get the following error. Cannot insert explicit value for identity column in table 'MemberSelectedOptions' when IDENTITY_INSERT is set to OFF. I don't want to set IDENTIY_INSERT to ON because I want the identity column in the db to manage the values. The SQL that is run is the following; where you can clearly see the insert. insert into dbo.MemberSelectedOptions (OptionStatusCd, EffectiveDate, TermDate, SelectionStatusDate, SysLstUpdtUserId, SysLstTrxDtm, SourceApplication, GroupId, MemberId, OptionId, SeqNo) values (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?) What am I missing?

• mysql ON DUPLICATE KEY UPDATE

  - by julio

  Hi-- I'm stuck on a mySQL query using ON DUPLICATE KEY UPDATE. I'm getting the error: mySQL Error: 1062 - Duplicate entry 'hr2461809-3' for key 'fname' The table looks like this: id int(10) NOT NULL default '0', picid int(10) unsigned NOT NULL default '0', fname varchar(255) NOT NULL default '', type varchar(5) NOT NULL default '.jpg', path varchar(255) NOT NULL default '', PRIMARY KEY (id), UNIQUE KEY fname (fname), KEY picid (propid) ) ENGINE=MyISAM DEFAULT CHARSET=utf8; And the query that's breaking is this: INSERT INTO images SET picid=732, fname='hr2461809-3', path='pictures/' ON DUPLICATE KEY UPDATE picid=732, fname='hr2461809-3', path='pictures/' I'm using a very similar query elsewhere in the app with no issues. I'm not sure why this one breaks. I expected that when the UNIQUE KEY on fname gets violated, that it would simply update the row where the violation occurred? Thanks for any help

• Oracle: delete suddenly taking a long time

  - by Damo

  Hi We have a feed process which runs every day of the year. As part of that we delete every row from a table (approx 1 million rows) every day, repopulate it using 5 different stored procedures and then commit the transaction. This is the only commit statement that we call. All of a sudden the delete has started takign about 2 hours to complete. The delete is also very simple (delete from T_PROFILE_WORK) This has worked perfectly well for the past year, but in the past week i have noticed this issue. Any help on this is greatly appreciated Thanks Damien

• Does DB2 OS/390 BLOB support .docx file

  - by Barry

  ASP.net app inserts .docx fileinto a row on DB2 OS/390 Blob table. A different VB.net app gets the DB2 OS/390 Blob data. When Microsoft Word tries to open the .docx file Microsoft Word pops up a message that the data is corrupted. Word will fix the data so the file can be viewed. I've seen some examples where .docx can be converted to .doc but they only talk about stripping out the text. Some of our .docx have pictures in them. Any ideas?

• CSS sticky footer makes scroll bar unscrollable in IE 8

  - by maraujop

  I'm using this sticky footer in my website: http://www.cssstickyfooter.com/using-sticky-footer-code.html It is fully working in Firefox, Chrome, IE7, but not IE8. In IE8 the scrollbar appears but doesn't work, and I don't have any other way to move down. I'm using the conditional statement that appears in the web: <!--[if !IE 7]> <style type="text/css"> #wrap {display:table;height:100%} </style> <![endif]--> Sorry, but I can't post an address, I don't have a server online right now with the web.

• Python: Time a code segment for testing performance (with timeit)

  - by Mestika

  Hi, I've a python script which works just as it should but I need to write the time for the execution. I've gooled that I should use timeit but I can't seem to get it to work. My Python script looks like this: import sys import getopt import timeit import random import os import re import ibm_db import time from string import maketrans myfile = open("results_update.txt", "a") for r in range(100): rannumber = random.randint(0, 100) update = "update TABLE set val = %i where MyCount >= '2010' and MyCount < '2012' and number = '250'" % rannumber #print rannumber conn = ibm_db.pconnect("dsn=myDB","usrname","secretPWD") for r in range(5): print "Run %s\n" % r ibm_db.execute(query_stmt) query_stmt = ibm_db.prepare(conn, update) myfile.close() ibm_db.close(conn) What I need it the time it takes the execution of the query and written to the file "results_update.txt". The purpose is to test an update statement for my database with different indexes and tuning mechanisms. Sincerely Mestika

• CSS - Overlapping divs

  - by Jens Törnell

  I have no code to start with. I want to add 2 divs overlapping on each other and then use the new CSS3 Rotate function. The effect I want to create is shown on this page Requirements I don't want to use images I don't mind using CSS3 It should be easy to align the whole thing in the center (which makes it harder to use position: absolute;). It's going to be content below the boxed content (which makes it harder to use position: absolute;). If it's possible without too much position: absolute; it's better. I prefer table free solutions. Have fun!

• How do you encode an apostrophe so that it's searchable in mysql?

  - by Yegor

  I don't think that was the most clear question, but an example should make it a little clearer. I have a table filled with movie names, some of which contain apostrophes. I have a search box which is used to find movies. If I perform searches via mov_title = '$search_keywords' it all works, but this method will not yield any results for partial searches, so I have to use this mov_title LIKE '%$search_keywords%' This method works fine for titles that are A-Za-z0-9, but if a title has an apostrophe, it's not able to find the movie, even if I do an exact match. Before the titles are stored in the DB, I put them through this: $search_keywords = htmlspecialchars(mysql_escape_string($_GET["search_keywords"])); So in the DB, there is a forward slash before every single apostrophe. The only way to match a movie title with an apostrophe is to physically put a forward slash in front of the apostrophe, in the search box. This seems so trivial, and I'm sure the solution is painfully obvious, but I'm just not seeing it.

• LinqToSql: How can I create a projection to adhere to DRY?

  - by mhutter

  Just wondering if there is a way to take some of the repitition out of a LINQ to SQL projected type. Example: Table: Address Fields: AddressID, HouseNumber, Street, City, State, Zip, +20 more Class MyAddress: AddressID, HouseNumber, Street (Only 3 fields) LINQ: from a in db.Addresses select new MyAddress { AddressID = a.AddressID, HouseNumber = a.HouseNumber, Street = a.Street } The above query works perfectly, and I understand why something like this will return all 20+ fields in each row: from a in db.Addresses select new MyAddress(a); class MyAddress { public MyAddress(Address a) { this.AddressID = a.AddressID, this.HouseNumber = a.HouseNumber, this.Street = a.Street } } Which leads me to my Question: Is it possible to implement some kind of helper function or extension method to "map" from the LINQ model to MyAddress yet only return the necessary fields in the query result rather than all of the fields?

• Performing multiple fetches in Core Data within the same view

  - by yesimarobot

  I have my CD store setup and everything is working. Once my initial fetch is performed, I need to perform several fetches based on calculations using the data from my first fetch. The examples provided from Apple are great, and helped me get everything going but I'm struggling with executing successive fetches. Any suggestions, or tutorial links are appreciated. Table View loads data from CD store. When a user taps a row it pushes a detail view The detail view loads details from CD. [THE ABOVE STEPS ARE ALL WORKING] I perform several calculations on the data fetched in the detail view. I need to then perform several other fetches based on the results of my calculations.

• MySQL command-line tool: How to find out number of rows affected by a DELETE?

  - by ambivalence

  I'm trying to run a script that deletes a bunch of rows in a MySQL (innodb) table in batches, by executing the following in a loop: mysql --user=MyUser --password=MyPassword MyDatabase < SQL_FILE where SQL_FILE contains a DELETE FROM ... LIMIT X command. I need to keep running this loop until there's no more matching rows. But unlike running in the mysql shell, the above command does not return the number of rows affected. I've tried -v and -t but neither works. How can I find out how many rows the batch script affected? Thanks!

• django modeling

  - by SledgehammerPL

  Concept: Drinks are made of components. E.g. 10ml of Vodka. In some receipt the component is very particular (10ml of Finlandia Vodka), some not (10 ml of ANY Vodka). I wonder how to model a component to solve this problem - on stock I have particular product, which can satisfy more requirements. The model for now is: class Receipt(models.Model): name = models.CharField(max_length=128) (...) components = models.ManyToManyField(Product, through='ReceiptComponent') def __unicode__(self): return self.name class ReceiptComponent(models.Model): product = models.ForeignKey(Product) receipt = models.ForeignKey(Receipt) quantity = models.FloatField(max_length=9) unit = models.ForeignKey(Unit) class Admin: pass def __unicode__(self): return unicode(self.quantity!=0 and self.quantity or '') + ' ' + unicode(self.unit) + ' ' + self.product.genitive class Product(models.Model): name = models.CharField(max_length = 128) (...) class Admin: pass def __unicode__(self): return self.name class Stock(Store): products = models.ManyToManyField(Product) class Admin: pass def __unicode__(self): return self.name I think about making some table which joins real product (on stock) with abstract product (receiptcomponent). But maybe there's easy solution?

• SQL Server 2000 - Filter by String Length

  - by user208662

  Hello, I have a database on a SQL Server 2000 server. This database has a table called "Person" that has a field call "FullName" that is a VARCHAR(100). I am trying to write a query that will allow me to get all records that have a name. Records that do not have a name have a FullName value of either null or an empty string. How do I get all of the Person records have a FullName? In other words, I want to ignore the records that do not have a FullName. Currently I am trying the following: SELECT * FROM Person p WHERE p.FullName IS NOT NULL AND LEN(p.FullName) > 0 Thank you

• How can I clean up this SELECT query?

  - by Cruachan

  I'm running PHP 5 and MySQL 5 on a dedicated server (Ubuntu Server 8.10) with full root access. I'm cleaning up some LAMP code I've inherited and I've a large number of SQL selects with this type of construct: SELECT ... FROM table WHERE LCASE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE( strSomeField, ' ', '-'), ',', ''), '/', '-'), '&', ''), '+', '') ) = $somevalue Ignoring the fact that the database should never have been constructed to require such a select in the first place, and the $somevalue field will need to be parameterised to plug the gaping security hole, what is my best option for fixing the WHERE condition into something less offensive? If I was using MSSQL or Oracle I'd simply put together a user-defined function, but my experience with MySQL is more limited and I've not constructed a UDF with it before, although I'm happy coding C. Update: For all those who've already raised their eyebrows at this in the original code, $somevalue is actually something like $GET['product']—there are a few variations on the theme. In this case the select is pulling the product back from the database by product name—after stripping out characters so it matches what could be previously passed as a URI parameter.

• Can Grails exceptionHandler support the following Error Handling Flow

  - by Andrew

  In my rails app that I am porting to grails whenever an unexpected error occurs I intercept the error automatically and display a form to the user informing them that an error has occured and asking them for further information. Meanwhile, as the form is rendered I write the stack trace and other information about who was logged in to a database table. Then if the form is submitted I add that information to the error report. I cannot tell from the exceptionHandler documentation and BootStrap examples whether that will allow me to grab all the information including various session and request parameters and then stuff them into a database and then post a form. Any thoughts?

• SQL Compact Edition 3.5 SP 1 - LockTimeOutException - how to debug?

  - by Bob King

  Intermittently in our app, we encounter LockTimeoutExceptions being throw from SQL CE. We've recently upgraded to 3.5 SP 1, and a number of them seem to have gone away, but we still do see them occasionally. I'm certain it's a bug in our code (which is multi-threaded) but I haven't been able to pin it down precisely. Does anyone have any good techniques for debugging this problem? The exceptions log like this (there's never a stack trace for these exceptions): SQL Server Compact timed out waiting for a lock. The default lock time is 2000ms for devices and 5000ms for desktops. The default lock timeout can be increased in the connection string using the ssce: default lock timeout property. [ Session id = 6,Thread id = 7856,Process id = 10116,Table name = Product,Conflict type = s lock (x blocks),Resource = DDL ] Our database is read-heavy, but does seldom writes, and I think I've got everything protected where it needs to be. EDIT: SQL CE already automatically uses NOLOCK http://msdn.microsoft.com/en-us/library/ms172398(sql.90).aspx

• SQL select statement - returning records starting with variable length string

  - by alpheus

  I am using an alphabetical sorting feature and need a SQL statement to return records beginning with a variable length string. However, records also need to be returned if there are periods, spaces, or dashes between any of the characters in the string. For example, the string could be "M" (easy). Or "MA" (in which case it needs to return records starting with "MA", "M.A", "M A", and "M-A"). Or "MAA", and so on. This is the statement I have so far: "SELECT * from table where LEFT(name," + value.Length + ")='" + value + "'" But I can't work out how to get it to return results where there are periods, spaces or dashes in name. Any help constructing the statement would be great.

• VBA SQL Loop using QODBC

  - by Dan

  I am trying to loop through an existing table (tblSalesOrder) and I need to run through every line (where they relate to that particular customer) and write each line into an SQL statement and execute it. What is the easiest way to go about this procedure? The number of lines will need to be counted prior to data being written via SQL to a QuickBooks database. I can code something similar in php using the code below, but I am unsure how to convert this into a VBA friendly format: $sql_count = "SELECT count(*) FROM tblSalesOrder WHERE Customer='cust_number'"; execute_query($sql_count) When the above value is greater than 0, the vba code should loop through the queries. Thanks everyone
