  • mysql_fetch_object on complex objects

    - by Arsenal
    Say for example I have the follwoing DB structure Table book id title ... Table Author id name ... Table BookAuthor id bookid authorid And in PHP I have the following object class Book { var $id; var $title; var $authors = array(); function Book() {} } class Author { var $id; var $name; function Author(){} } Now, would it be possible using mysql_fetch_object to retrieve the bookobject including the authors as an array of author objects? If it's possible I'm pretty sure you'll need the basic inner join query SELECT * FROM tblbook INNER JOIN tblbookauthor on ... (wel you get the point) Is it possible? thanks!

  • ManyToManyField error when having recursive structure. How to solve it?

    - by luc
    Hello, I have the following table in the model with a recursive structure (a page can have children pages) class DynamicPage(models.Model): name = models.CharField("Titre",max_length=200) parent = models.ForeignKey('self',null=True,blank=True) I want to create another table with manytomany relation with this one: class UserMessage(models.Model): name = models.CharField("Nom", max_length=100) page = models.ManyToManyField(DynamicPage) The generated SQL creates the following constraint: ALTER TABLE `website_dynamicpage` ADD CONSTRAINT `parent_id_refs_id_29c58e1b` FOREIGN KEY (`parent_id`) REFERENCES `website_dynamicpage` (`id`); I would like to have the ManyToMany with the page itself (the id) and not with the parent field. How to modify the model to make the constraint using the id and not the parent? Thanks in advance

  • If and only if condition SQL -- SQL server 2008

    - by user494901
    I'm writing a SQL statement to select a user on a table if that user does not exist on another table, then I want to pull in all their data from another table then I'll be outputting all that in Coldfusion. How do I do this? I have tried, my atempt is below: pro_profile == All employees mod_userStatus == All Professional Staff members I am doing the not exists to remove professional stuff to just get our student staff. mod_StudentCertifications is a listing of the certifications they (students) hold. If we do an AND statement between the where statements it returns no users, or only users that meet both conditions, if we do an OR it will return users with only 1 condition. I need it first Match the not exists then proceed to the exists statement. Is that do able? Here's my Statement: SELECT profileID, firstName, lastName FROM pro_Profile WHERE not exists ( SELECT profileID FROM mod_userStatus WHERE mod_userStatus.profileID = pro_Profile.profileID ) OR exists ( SELECT cprAdultExp, cprInfantChildExp, cprFPRExp, aedExp, firstAidExp, emtExp, waterSafetyInstructionExp, bloodPathogensExp, oxygenAdminExp, lifegaurdingExp, wildernessResponderExp, notes FROM mod_StudentCertifications WHERE mod_StudentCertifications.profileID = pro_Profile.profileID );

  • How can keep track of the index path of a button in a tableview cell?

    - by Jake
    I have a table view where each cell has a button accessory view. The table is managed by a fatchedresults controller and is frequently reordered. I want to be able to press a button and be able to obtain the index path of the pressed button's tableviewcell. I've been trying to get this working for days by storing the row of the button in it's tag, but when the table get's reordered the row becomes incorrect and I keep failing at reordering the tags correctly when a change is made. Any new ideas on how to keep track of the button's cell's index path? Thanks so much for any help.

  • How to enable an AdventureWorks database in a web application?

    - by salvationishere
    I am developing a C#/SQL ASP.NET web application in VS 2008. I want the users to be able to select an Adventureworks table and then an input file. The user is then able to map columns from the file with the selected table. This app works fine now in VS. But when I Browse in IIS, it doesn't show any of the tables. I think this is because currently Adventureworks connection string is integrated security (Windows authentication). If I want users to be able to select a table, do I have to change connection to SQL Server authentication? And if so, is the only way to do this to reinstall SQL Server? Or can I just reinstall Adventureworks? And if I reinstall SQL Server, do I need to reinstall VS also for this to work? This could be painful...

  • Cannot running next process when a variable save no value

    - by bruine
    First, I wanna compare between 2 tables tb_wrapper and tb_summary to get the data in the tb_wrapper that doesn't exist in the tb_summary then save in $link. If I don't get the same data, I want to print the result $link. When I don't get the not same data, I want it to go to another process. Here's the code : $q2 = mysql_query(" SELECT a.doc_url FROM tb_wrapper a LEFT JOIN tb_summary b ON a.doc_name = b.doc_summ WHERE b.doc_summ IS NULL"); while ($row = mysql_fetch_array($q2)){ $link = $row['doc_url']; if (!$link){ include 'next_process.php'; } else { print_r($link); } } it doesn't work. When I don't get the not same data or $link not save a value. table : CREATE TABLE tb1 (`id` int, `doc_name` varchar(100), `doc_url` varchar(50)) } CREATE TABLE tb2 (`id` int, `doc_summ` varchar(100)) }

  • SQL: joining multiples tables into one.

    - by Graveen
    I have 4 tables. r1, r2, r3 and r4. The table columns are the following: rId | rName I want to have, in fine, an unique table - let's call it R. Obviously, R will have the following structure: rTableName | rId | rName I'm looking for a solution, and the more natural for me is to: add a single column to all rX insert this column the table name i'm processing generate SQLs and concatenate them all Although I see exactly how to perform 1 and 3 with batching, editing, etc... (I have only to perform it once and for all), I don't see how to do the point 2: self-getting the tablename to insert into SQL. Have you an idea / or a different way to do that could solve my problem? Note: In fact, there are 250+ rX tables. That's why i can't do this manually. Note2: Precisely, this is with MySQL.

  • Codeigniter setting multiple where conditions, how to unset one

    - by Dustin
    I've got a script that is a notify_url from paypal that is supposed to update multiple tables in my database using the following code: //update first table $this-db-where('someid', $somid); $this-db-update('table', $data); ///update second table $this-db-where('somesecondid', $somesecondid) $this-db-update('anothertable', $data2); Then I get the following error: Unknown column 'somesecondid' in 'where clause' UPDATE anothertable SET avail = 0 WHERE someid = '13' AND somesecondid = '199' So codeigniter is combining those where clauses into a single query. Is there a way to unset the first one so it only has "UPDATE anothertable SET avail=0 WHERE somesecondid = 199" ? Thanks!

  • Hibernate Many-To-One Foreign Key Default 0

    - by user573648
    I have a table where the the parent object has an optional many-to-one relationship. The problem is that the table is setup to default the fkey column to 0. When selecting, using fetch="join", etc-- the default of 0 on the fkey is being used to try over and over to select from another table for the ID 0. Of course this doesn't exist, but how can I tell Hibernate to treat a value of 0 to be the same as NULL-- to not cycle through 20+ times in fetching a relationship which doesn't exist? <many-to-one name="device" lazy="false" class="Device" not-null="true" access="field" cascade="none" not-found="ignore"> <column name="DEVICEID" default="0" not-null="false"/>

  • Copying a database into a new database including structure and data

    - by Jason
    In phpMyAdmin under operations I can "Copy database to:" and select Structure and data CREATE DATABASE before copying Add AUTO_INCREMENT value I need to be able to do that without using phpMyAdmin. I know how to create the database and user. I have a source database that's a shell that I can work from so all I really need is the how to copy all the table structure and data part. (I know, the harder part) system() & exec() are not options for me which rules out mysqldump. (I think) How can I loop through each table and recreate it's structure and data? Is it just looping through the results of SHOW TABLES then for each table looping through DESCRIBE tablename Then, is there an easy way for getting the data copied?

  • Is there a best practice for maintaining history in a database?

    - by Pete
    I don't do database work that often so this is totally unfamiliar territory for me. I have a table with a bunch of records that users can update. However, I now want to keep a history of their changes just in case they want to rollback. Rollback in this case is not the db rollback but more like revert changes two weeks later when they realized that they made a mistake. The distinction being that I can't have a transaction do the job. Is the current practice to use a separate table, or just a flag in the current table? It's a small database, 5 tables each with < 6 columns, < 1000 rows total.

  • Simple 'database' in c++

    - by DevAno1
    Hello. My task was to create pseudodatabase in c++. There are 3 tables given, that store name(char*), age(int), and sex (bool). Write a program allowing to : - add new data to the tables - show all records - sort tables with criteria : - name increasing/decreasing - age increasing/decreasing - sex Using function templates is a must. Also size of arrays must be variable, depending on the amount of records. I have some code but there are still problems there. Here's what I have: Function tabSize() for returning size of array. But currently it returns size of pointer I guess : #include <iostream> using namespace std; template<typename TYPE> int tabSize(TYPE *T) { int size = 0; size = sizeof(T) / sizeof(T[0]); return size; } How to make it return size of array, not its pointer ? Next the most important : add() for adding new elements. Inside first I get the size of array (but hence it returns value of pointer, and not size it's of no use now :/). Then I think I must check if TYPE of data is char. Or am I wrong ? // add(newElement, table) template<typename TYPE> TYPE add(TYPE L, TYPE *T) { int s = tabSize(T); //here check if TYPE = char. If yes, get the length of the new name int len = 0; while (L[len] != '\0') { len++; } //current length of table int tabLen = 0; while (T[tabLen] != '\0') { tabLen++; } //if TYPE is char //if current length of table + length of new element exceeds table size create new table if(len + tabLen > s) { int newLen = len + tabLen; TYPE newTab = new [newLen]; for(int j=0; j < newLen; j++ ){ if(j == tabLen -1){ for(int k = 0; k < len; k++){ newTab[k] = } } else { newTab[j] = T[j]; } } } //else check if tabLen + 1 is greater than s. If yes enlarge table by 1. } Am I thinking correct here ? Last functions show() is correct I guess : template<typename TYPE> TYPE show(TYPE *L) { int len = 0; while (L[len] == '\0') { len++; } for(int i=0; i<len; i++) { cout << L[i] << endl; } } and problem with sort() is as follows : Ho can I influence if sorting is decreasing or increasing ? I'm using bubble sort here. template<typename TYPE> TYPE sort(TYPE *L, int sort) { int s = tabSize(L); int len = 0; while (L[len] == '\0') { len++; } //add control increasing/decreasing sort int i,j; for(i=0;i<len;i++) { for(j=0;j<i;j++) { if(L[i]>L[j]) { int temp=L[i]; L[i]=L[j]; L[j]=temp; } } } } And main function to run it : int main() { int sort=0; //0 increasing, 1 decreasing char * name[100]; int age[10]; bool sex[10]; char c[] = "Tom"; name[0] = "John"; name[1] = "Mike"; cout << add(c, name) << endl; system("pause"); return 0; }

  • Indexing XMLType columns

    - by Chris
    Hello, I am working with a XMLType and currently experiencing significant performance issues and would like to incorporate indexing to the column type. Currently I am taking the approach of using the XMLTable() and XQuery functions to create a virtual table. I would like to use this Virtual Table to create a function based index on the table containing the XMLType, but I am receiving this error: Error report: SQL Error: ORA-00907: missing right parenthesis 00907. 00000 - "missing right parenthesis" *Cause: *Action: This is the index.. any assistance would be greatly appreciated.

  • Creating custom ribbon with SQL Server linked Access application

    - by andy
    I'm just learning about creating custom ribbons in Access 2010, but I'm running into an issue. The Access application I'm working with is connected to a SQL Server backend (connected, not just linked tables). As I understand it, the USysRibbons table needs to exist in the Access application itself, and not in a connected SQL Server. How does one go about creating a table in an Access application that is already linked to a SQL Server? I tried creating the table in a blank database and then importing it into the Access application without any luck.

  • mysql select where count = 0

    - by david parloir
    Hi, In my db, I have a "sales" table and a "sales_item". Sometimes, something goes wrong and the sale is recorded but not the sales item's. So I'm trying to get the salesID from my table "sales" that haven't got any rows in the sales_item table. Here's the mysql query I thought would work, but it doesn't: SELECT s.* FROM sales s NATURAL JOIN sales_item si WHERE s.date like '" . ((isset($_GET['date'])) ? $_GET['date'] : date("Y-m-d")) . "%' AND v.sales_id like '" . ((isset($_GET['shop'])) ? $_GET['shop'] : substr($_COOKIE['shop'], 0, 3)) ."%' HAVING count(si.sales_item_id) = 0; Any thoughts?

  • MS Sync framework - Identity crisis resolution by partitioning the primary key.

    - by user326136
    Hello, We implementing offline feature to an existing application. We have implemented the syn with SQL Server internal change tracking and over WCF using MS Sync Framework (http://msdn.microsoft.com/en-us/sync/default.aspx) All of our tables have primary key as integer, we cannot move to GUID. So as you are thinking we will have identity crises between applications. So we decided to go with the way Merge replication does(http://msdn.microsoft.com/en-us/library/aa179416(SQL.80).aspx) partition the primary key range. Below is the example scenario - Server Table A - ID Range - 0 to 100 Client 1 Table A - ID Range - 101 to 200 Client 2 Table A - ID Range - 201 to 300 how to implement this ? i know we can use BCC CHECKIDENT (yourtable, reseed, value) CHECK (([ID]<=(100))) but this does not solve the issue.... Merge replication provides an option of "Not for replication"(http://msdn.microsoft.com/en-us/library/aa237102(SQL.80).aspx) to achieve insert form clients and still maintain the set range.. can i use that somehow here? please help...

  • Transform LINQ Dataset into a Matrix for export

    - by Mad Halfling
    Hi folks, I've got a data table with columns in which include Item, Category and Value (and others, but those are the only relevant ones for this problem) that I access via LINQ in a C# ASP.Net MVC app. I want to transform these into a matrix and output that as a CSV file to pull into Excel as matrix with the items down the side, the categories across the top and the values in the row cells. However, I don't know how many, or what, categories there will be in this table, nor will there always be a record for each item/category combination. I've written this by looping round, getting my "master category" list, then looking again for each item, filling in either blank or Value, depending on whether the item/category record exists, but as there are currently 27000 records in the table, this isn't as fast as I'd like. Is there a slicker and faster way I can do this, maybe via LINQ (firing into a quicker SQL statement so the DB server can do the leg-work), or will any method essentially come back to what I am doing? Thx MH
