  • copy an identity column into another table

    - by slake
    I have 2 tables that are related,both have identity columns for primary keys and i am using a vb form to insert data into them,My problem is that i cannot get the child table to get the primary key of the parent table and use this as its foreign key in my database. the data is inserted fine though no foreign key constraint is made.I am wondering if a trigger will do it and if so how. All my inserting of data is done in vb. The user wont insert any keys. all these are identity columns that are auto generated. If a trigger is my way out please illustrate with an example. If there is another way i can do this in VB itself then please advise and an example will be greatly appreciated Thanks in advance

  • AWS ECS API - ItemLookup - Get item's (EAN) SalesRank by BrowseNode

    - by Lysender
    I'm using amazon japan, using ItemLookup. We already have the EAN numbers (used as ItemId). It was working well until we need to modify the SalesRank. The previous SalesRank returned is for the whole SearchIndex, ex: Books, Music, etc. What we want is to get the SalesRank for a specific BrowseNode. I don't know but it seems that it is not implemented on Amazon US. For example: http: // www . amazon . com / Slackware-Essentials-Cantrell-Johnson-Lumens/dp/1571763384/ref=sr_1_1?ie=UTF8&s=books&qid=1276142663&sr=1-1 The book above only shows the SalesRank (Bestsellers Rank) but on Japan Amazon: http://www.amazon.co.jp/Slackware-Linux-Dummies/dp/0764506897/ref=sr_1_4?ie=UTF8&s=english-books&qid=1276142708&sr=1-4 It shows SalesRank for other three different BrowseNodes. We need to get the SalesRank for a specific BrowseNode for a given ItemId or by any other means. Any ideas guys? TIA

  • How to stable_sort without copying?

    - by Mehrdad
    Why does stable_sort need a copy constructor? (swap should suffice, right?) Or rather, how do I stable_sort a range without copying any elements? #include <algorithm> class Person { Person(Person const &); // Disable copying public: Person() : age(0) { } int age; void swap(Person &other) { using std::swap; swap(this->age, other.age); } friend void swap(Person &a, Person &b) { a.swap(b); } bool operator <(Person const &other) const { return this->age < other.age; } }; int main() { static size_t const n = 10; Person people[n]; std::stable_sort(people, people + n); }

  • Duplicate / Copy records in the same MySQL table

    - by Digits
    I have been looking for a while now but I can not find an easy solution for my problem. I would like to duplicate a record in a table, but of course, the unique primary key needs to be updated. I have this query: INSERT INTO invoices SELECT * FROM invoices AS iv WHERE iv.ID=XXXXX ON DUPLICATE KEY UPDATE ID = (SELECT MAX(ID)+1 FROM invoices) the problem is that this just changes the ID of the row instead of copying the row. Does anybody know how to fix this ? Thank you verrry much, Digits //edit: I would like to do this without typing all the field names because the field names can change over time.

  • TinyMce plugin, how to copy 'Link' functionality.

    - by Tom
    I'm creating a new plugin for TinyMce. However I cannot find any examples to see some of the functionality I've seen in other plugins. I've read their source code but I cannot find where it is done: When you click on an 'A' element, the link/unlink buttons in the taskbar become enabled. When you right click on an 'A' element, then click on the "Insert/edit link" icon that is shown in the popup menu, the "Insert/edit link" window is setup (has all the attributes for that particular link) prefilled. Could you suggest somewhere where I could learn how to do this? A file and line number is fine. Thanks in advance.

    - by No Body
    Just need to clarify this one, If I have the below interface public interface IRepository<T> { T Add(T entity); } when implementing it, does checking for duplication if entity is already existing before persist it is still a job of the Repository, or it should handle some where else?

  • Finding Most Recent Order for a Particular Item

    - by visitor
    I'm trying to write a SQL Query for DB2 Version 8 which retrieves the most recent order of a specific part for a list of users. The query receives a parameter which contains a list of customerId numbers and the partId number. For example, Order Table OrderID PartID CustomerID OrderTime I initially wanted to try: Select * from Order where OrderId = ( Select orderId from Order where partId = #requestedPartId# and customerId = #customerId# Order by orderTime desc fetch first 1 rows only ); The problem with the above query is that it only works for a single user and my query needs to include multiple users. Does anyone have a suggestion about how I could expand the above query to work for multiple users? If I remove my "fetch first 1 rows only," then it will return all rows instead of the most recent. I also tried using Max(OrderTime), but I couldn't find a way to return the OrderId from the sub-select. Thanks! Note: DB2 Version 8 does not support the SQL "TOP" function.

  • load different images for each item on the listbox

    - by user161179
    Javascript: function changeMap() { imagesource = "http://maps.google.com/maps/api/staticmap?size=500x500&maptype=hybrid&zoom=16&sensor=false&markers=color:blue|label:K|28.541250,77.204100" ; mapimage.src = imagesource ; } Html code : <select name="choose_colony" id="choose_colony" size="8" onchange="changeMap()" style="float: left;"> <option value="1" >Big apartments</option> . . <option value="999">plaza</option> </select> <img name="mapimage" src="" alt="Select your Colony" style="float: right;"> In this whenever a selection on the listbox is made changeMap is called and an image is loaded. What I want is for a different image to be loaded everytime depending upon the option selected . there will be over 2000 entries in the listbox. Considering this what is the best way of going about this ? I can figure out the if/then part , but my main question is whether its ok to put all the 2000 long image addresses in the html file itself ? I hope I was clear ..

  • memcpy does not copy the data

    - by user437777
    I am caught up with a weird problem. I have one build that copies data using memcpy, while another build does not. I don't understand why, because the relevant file is still the same. I am using following code: memcpy(pxCurrentInfo, &pxInfoBuffer->axgInfoBuffer[0], sizeof(tInfo)); Data in pxInfoBuffer is fine. When I check pxCurrentInfo they are all 0s. tInfo is a structure. To give a pointer, when I put the break point and change the value pxCurrentInfo->xDL.eMethod=0 it automatically updates/copies all the correct info from pxInfoBuffer->axgInfoBuffer[0], afterwards. I don't know why.
