  • SQL Cartesian product joining table to itself and inserting into existing table

    - by Emma
    I am working in phpMyadmin using SQL. I want to take the primary key (EntryID) from TableA and create a cartesian product (if I am using the term correctly) in TableB (empty table already created) for all entries which share the same value for FieldB in TableA, except where TableA.EntryID equals TableA.EntryID So, for example, if the values in TableA were: TableA.EntryID TableA.FieldB 1 23 2 23 3 23 4 25 5 25 6 25 The result in TableB would be: Primary key EntryID1 EntryID2 FieldD (Default or manually entered) 1 1 2 Default value 2 1 3 Default value 3 2 1 Default value 4 2 3 Default value 5 3 1 Default value 6 3 2 Default value 7 4 5 Default value 8 4 6 Default value 9 5 4 Default value 10 5 6 Default value 11 6 4 Default value 12 6 5 Default value I am used to working in Access and this is the first query I have attempted in SQL. I started trying to work out the query and got this far. I know it's not right yet, as I’m still trying to get used to the syntax and pieced this together from various articles I found online. In particular, I wasn’t sure where the INSERT INTO text went (to create what would be an Append Query in Access). SELECT EntryID FROM TableA.EntryID TableA.EntryID WHERE TableA.FieldB=TableA.FieldB TableA.EntryID<>TableA.EntryID INSERT INTO TableB.EntryID1 TableB.EntryID2 After I've got that query right, I need to do a TRIGGER query (I think), so if an entry changes it's value in TableA.FieldB (changing it’s membership of that grouping to another grouping), the cartesian product will be re-run on THAT entry, unless TableB.FieldD = valueA or valueB (manually entered values). I have been using the Designer Tab. Does there have to be a relationship link between TableA and TableB. If so, would it be two links from the EntryID Primary Key in TableA, one to each EntryID in TableB? I assume this would not work because they are numbered EntryID1 and EntryID2 and the name needs to be the same to set up a relationship? If you can offer any suggestions, I would be very grateful.

  • In a pre-commit hook - how to access/compare current and previous versions of files

    - by EthanML
    I'm trying to add to our existing pre-commit SVN hook so that it will check for and block an increase in file size for files in specific directory/s. I've written a python script to compare two file sizes, which takes two files as arguments and uses sys.exit(0) or (1) to return the result, this part seems to work fine. My problem is in calling the python script from the batch file, how to reference the newly committed and previous versions of each file? The existing code is new to me and a mess of %REPOS%, %TXN%s etc and I'm not sure how to go about using them. Is there a simple, standard way of doing this? It also already contains code to loop through the changed files using svnlook changed, so that part shouldn't be an issue. Thanks very much

  • php convert images and upload to amazon s3

    - by faraklit
    I am looking for a best practice while uploading images to amazon s3 server and serving from there. We need four different sizes of an image. So just after image upload we convert the image and scale in 4 different widths and heights. And then we send them to the amazon s3 using official php api. // ... // image conversions, bucket setting, s3 initialization etc. $sizes= array("", "48", "64", "128"); foreach($sizes as $size) { $filename = $upload_path.$dest_file.$size.$ext; $s3->batch()->create_object($bucket, , array( 'fileUpload' => $filename, 'acl' => AmazonS3::ACL_PUBLIC, )); } But for a 1M image the client sometimes wait up to 30 seconds which is a very long time. Instead of sending images immediately to S3, it may be better to add them to a job queue. But the user should see the uploaded image immediately.

  • Questions About SQl BulkCopy

    - by chobo2
    Hi I am wondering how can do a mass insert and bulk copy at the same time? I have 2 tables that should be affect by the bulk copy as they both depend on each other. So I want it that if while inserting table 1 a record dies it gets rolled back and table 2 never gets updated. Also if table 1 inserts good and table 2 an update fails table 1 gets rolled back. Can this be done with bulk copy?

  • How would I implement code in a .h file into the main.cpp file?

    - by Lea
    I have a c++ project I am working on. I am a little stumped at the moment. I need a little help. I need to implement code from the .h file into the main.cpp file and I am not sure how to do that. For example code code from main.cpp: switch (choice){ case 1: // open an account { cout << "Please enter the opening balence: $ "; cin >> openBal; cout << endl; cout << "Please enter the account number: "; cin >> accountNum; cout << endl; break; } case 2:// check an account { cout << "Please enter the account number: "; cin >> accountNum; cout << endl; break; } and code from the .h file: void display(ostream& out) const; // displays every item in this list through out bool retrieve(elemType& item) const; // retrieves item from this list // returns true if item is present in this list and // element in this list is copied to item // false otherwise // transformers void insert(const elemType& item); // inserts item into this list // preconditions: list is not full and // item not present in this list // postcondition: item is in this list In the .h file you would need to use the void insert under transformer in the main.cpp under case 1. How would you do that? Any help is apprecaited. I hope I didn't confuse anyone on what I am needing to know how to do. Thanks

  • Entity framework 4 many-to-many insertion?

    - by Saxman
    Hi all, I'm not very familiar with the many-to-many insertion process using Entity Framework 4, POCO. I have a blog with 3 tables: Post, Comment, and Tag. A Post can have many Tags and a Tag can be in many Posts. Here are the Post and Tag models: public class Tag { public int Id { get; set; } [Required] [StringLength(25, ErrorMessage = "Tag name can't exceed 25 characters.")] public string Name { get; set; } public virtual ICollection<Post> Posts { get; set; } } public class Post { public int Id { get; set; } [Required] [StringLength(512, ErrorMessage = "Title can't exceed 512 characters")] public string Title { get; set; } [Required] [AllowHtml] public string Content { get; set; } public string FriendlyUrl { get; set; } public DateTime PostedDate { get; set; } public bool IsActive { get; set; } public virtual ICollection<Comment> Comments { get; set; } public virtual ICollection<Tag> Tags { get; set; } } Now when I'm adding a new post, I'm not sure what would be the right way to do. I'm thinking that I'll have a textbox where I can select multiple tags for that post (this part is already done), in my controller, I will check to see if the tag is already exists or not, if not, then I will insert the new tag. But I'm not even sure based on the models that I've created for EF, will they create a PostsTags table, or they are creating just a Tags and a Posts table and links between the two? How would I insert the new Post and set the tags to that post? Is it just newPost.Tags = Tags (where Tags are the one that got selected, do I even need to check to see if they already exists?), and then something like _post.Add(newPost);? Thanks.
