  • How can I tweak this split-tar-gz-archive script?

    - by Sai
    I came across this shell script that can be used to split an entire directory across multiple compressed files. I am interested in making a minor tweak to this script. Lets say I have n GB of files in a directory. I do not want the contents of a particular folder to be split across multiple tar files but inside the same file. I want the n MB folder to be fit within a single compressed file and the remaining (n GB -n MB) split across multiple files. I am not sure whether it is possible with this script. I was looking forward to some suggestions. Though the script has been well documented, it is quite complex to understand for me

  • T-SQL Re-Assigning Order Numbering

    - by Meltdown
    Say I have a table with a field called "ordernum" that denotes the order of a given set of rows. Now imagine that I delete one of these rows. What type of query would work best for re-assigning the order numbers so that they remain sequential? Here's an example: id group_id name ordernum active --------------------------------------------------- 0_____0______'Name1'___5__true 1_____0______'Name2'___4__true 2_____0______'Name3'___3__true 3_____1______'Name4'___2__true 4_____1______'Name5'__1__true 5_____1______'Name6'__NULL___false Now if I deleted the column with id='4' how would I reset the values in the 'ordernum' field for that specific group? Is this even possible? Or if I added a new row. (The first time the rows are created they are sorted by date, but then the user has the option to set the order himself.) In my table design I have a column 'active' boolean. If 'active' is set to false, then 'ordernum' is set to NULL. Otherwise it should be given an order number.

  • Creating items in groups in Rails

    - by LearnRails
    My product table is id type price location 1 chips $3 aisle3 I have a question with adding the products in groups. There is a quantity field(nonmodel) where the user can enter the quantity While adding a new product if the user enters: type: soda quantity: 3 Then there 3 records should be created in product model with type= soda like the following. id type 2 soda 3 soda 4 soda If user enters location: aisle4 quantity: 2 Then id location 5 ailse4 6 ailse4 Can you tell me how to pass the nonmodel field 'quantity' to the rails(model or controller) and how use it to add the products in groups as mentioned above? or should I create a column called quantity in my product table? Will the history be updated too for all these new records with after_create filter which I already have ? Is there any good tutorial or book which shows how to pass such nonmodel html/javascript fields from view to rails and then back to the view? Any help will be greatly appreciated. Thanks

Notice: Cost of the second query ist somewhat higher than for the first query. So the main question is: Why does the planner make the first decision, instead of the second? Also interesing: Via SET enable_seqscan TO false; i temp. disabled seq scans. Than the planner used indexes and hash joins, and the query still was slow. So the problem seems to be the hash join. Maybe someone can help in this confusing situation? thx, R.

  • SQLite and PostgreSql longtext

    - by Nik
    Hello all, Does anyone know how to change a column in SQLite and PostgreSQL to LONGTEXT? I have done so in MySQL successfully with: "ALTER TABLE projects MODIFY description LONGTEXT;" But this clause doesn't seem to work on SQLite. I tried hard to find documentation on PostgreSQL, but that site's format really makes people puke. SQLite's website is better but the only command I find relevant, alter table, doesn't seem to support changing column data type at all. ( infact, it doesn't even allow changing column name!!!) Thanks all!

  • SQL Server - Query Short-Circuiting?

    - by Sam Schutte
    Do T-SQL queries in SQL Server support short-circuiting? For instance, I have a situation where I have two database and I'm comparing data between the two tables to match and copy some info across. In one table, the "ID" field will always have leading zeros (such as "000000001234"), and in the other table, the ID field may or may not have leading zeros (might be "000000001234" or "1234"). So my query to match the two is something like: select * from table1 where table1.ID LIKE '%1234' To speed things up, I'm thinking of adding an OR before the like that just says: table1.ID = table2.ID to handle the case where both ID's have the padded zeros and are equal. Will doing so speed up the query by matching items on the "=" and not evaluating the LIKE for every single row (will it short circuit and skip the LIKE)?

  • Add UIView behind UITableView in UITableViewController code

    - by Drew C
    I would like to use a fixed image as the background in a simple grouped table view in my iPhone program. Unfortunately, no matter what I do, the background is always solid white. I have followed several supposed solutions on this site and others to no avail. Here is the relavant code in the viewDidLoad method of the table view controller class (note, this code uses a solid blue color rather than an image for simplicity's sake): self.tableView.opaque = NO; self.tableView.backgroundColor = [UIColor clearColor]; UIView *backgroundView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)]; backgroundView.backgroundColor = [UIColor blueColor]; [self.tableView.window addSubview:backgroundView]; [backgroundView release]; I suspect that I am not positioning the backgroundView view in the right place. I have tried sendToBack:, bringToFront:, and others but I always just get a white background. Is it possible to do this from within the UITableViewController? Must I use Interface Builder?

  • MySQL - how long to create an index?

    - by user293594
    Can anyone tell me how adding a key scales in MySQL? I have 500,000,000 rows in a database, trans, with columns i (INT UNSIGNED), j (INT UNSIGNED), nu (DOUBLE), A (DOUBLE). I try to index a column, e.g. ALTER TABLE trans ADD KEY idx_A (A); and I wait. For a table of 14,000,000 rows it took about 2 minutes to execute on my MacBook Pro, but for the whole half a billion, it's taking 15hrs and counting. Am I doing something wrong, or am I just being naive about how indexing a database scales with the number of rows?

  • MS Word: Mailmerge hyperlinks with query get url string with a mergefield.

    - by oterrada
    Hi, I'm trying to send an email merging one document (docx) with a contacts database (via OleDB). Using MSWord2007, it seems easy (it works for easy things: name, address, ...) but I can't find how fill an query-get url string with a merge field inside an hyperlink. An hyperlink like: Click here where here is an hyperlink to http://domain.com/[email protected] where [email protected] is the address of the contact, a merge field. I've tried the special/merge fields: {HYPERLINK "http://domain.com/test.php?contact={MERGEFIELD contactEmail}" \o "Here"} but it doesn't work, sometimes it merge only the first record and then send all the mails with the same address, I got this alternating the view with ALT+F9. This support doc doesn't work for me because I don't have the complete URL in my database for each contact, and I can't change the design of the table or add a view (it's from the CRM), I don't like to do it exporting the table and adding the field. Any idea? Thanks in advance,

  • Placing & deleting element(s) from a object (stack)

    - by Chris
    Hello, Initialising 2 stack objects: Stack s1 = new Stack(), s2 = new Stack(); s1 = 0 0 0 0 0 0 0 0 0 0 (array of 10 elements wich is empty to start with) top:0 const int Rows = 10; int[] Table = new int[Rows]; public void TableStack(int[] Table) { for (int i=0; i < Table.Length; i++) { } } My question is how exactly do i place a element on a stack (push) or take a element from the stack (pop) as the following: Push: s1.Push(5); // s1 = 5 0 0 0 0 0 0 0 0 0 (top:1) s1.Push(9); // s1 = 5 9 0 0 0 0 0 0 0 0 (top:2) Pop: int number = s1.Pop(); // s1 = 5 0 0 0 0 0 0 0 0 0 0 (top:1) 9 got removed Do i have to use get & set, and if so how exactly do i implent this with a array? Not really sure what to exactly use for this. Any hints highly appreciated. The program uses the following driver to test the Stack class (wich cannot be changed or modified): public void ExecuteProgram() { Console.Title = "StackDemo"; Stack s1 = new Stack(), s2 = new Stack(); ShowStack(s1, "s1"); ShowStack(s2, "s2"); Console.WriteLine(); int getal = TryPop(s1); ShowStack(s1, "s1"); TryPush(s2, 17); ShowStack(s2, "s2"); TryPush(s2, -8); ShowStack(s2, "s2"); TryPush(s2, 59); ShowStack(s2, "s2"); Console.WriteLine(); for (int i = 1; i <= 3; i++) { TryPush(s1, 2 * i); ShowStack(s1, "s1"); } Console.WriteLine(); for (int i = 1; i <= 3; i++) { TryPush(s2, i * i); ShowStack(s2, "s2"); } Console.WriteLine(); for (int i = 1; i <= 6; i++) { getal = TryPop(s2); //use number ShowStack(s2, "s2"); } }/*ExecuteProgram*/ Regards.

  • Query to find all the nodes that are two steps away from a particular node.

    Suppose I have two columns in a table that represents a graph, the first column is a FROMNODE and second one is TONODE. What I would like to know is that how will we find all the nodes that are two steps away from a particular node. Lets suppose I have a node numbered '1' and i would like to know all the nodes that are two steps away from it. I have tried(I am assuming the table name as graph) SELECT FROMNODE FROM GRAPH WHERE TONODE=1 (this is to select all the nodes that are connected to node 1, but I couldn't figure out how would I find all the nodes that are two steps away from node 1??)

  • SQL Like question

    - by mike
    Is there a way to reverse the SQL Like operator so it searches a field backwards? For example, I have a value in a field that looks like this "Xbox 360 Video Game". If I write a query like below, it returns the result fine. SELECT id FROM table WHERE title like "%Xbox%Game%" However, when I search like this, it doesn't find any results. SELECT id FROM table WHERE title like "%Video%Xbox%" I need it to match in any direction. How can I get around this?
