  • Improve Efficiency in Array comparison in Ruby

    - by user2985025
    Hi I am working on Ruby /cucumber and have an requirement to develop a comparison module/program to compare two files. Below are the requirements The project is a migration project . Data from one application is moved to another Need to compare the data from the existing application against the new ones. Solution : I have developed a comparison engine in Ruby for the above requirement. a) Get the data, de duplicated and sorted from both the DB's b) Put the data in a text file with "||" as delimiter c) Use the key columns (number) that provides a unique record in the db to compare the two files For ex File1 has 1,2,3,4,5,6 and file2 has 1,2,3,4,5,7 and the columns 1,2,3,4,5 are key columns. I use these key columns and compare 6 and 7 which results in a fail. Issue : The major issue we are facing here is if the mismatches are more than 70% for 100,000 records or more the comparison time is large. If the mismatches are less than 40% then comparison time is ok. Diff and Diff -LCS will not work in this case because we need key columns to arrive at accurate data comparison between two applications. Is there any other method to efficiently reduce the time if the mismatches are more thatn 70% for 100,000 records or more. Thanks

  • How can I select a column with no values?

    - by Lye
    I have a table with thousands of rows and hundreds of columns (not my design). I'm trying to find out which columns are never used so I can simplify the table a little. How can I find which of the columns have no value in all rows?

  • SQL Script To Generate a Database Dictionary **With Linked Fields**

    - by Albert
    I would like to generate a Data Dictionary for a SQL Server 2008 database that has one row for each field, and the following columns: table_name field_name data_type link_table (for when the field in question is a foreign key) link_field (for when the field in question is a foreign key) I can get the first 3 columns with something like the SQL script below...but I don't know how to get the last two columns of foreign key information. INFORMATION_SCHEMA.TABLE_CONSTRAINTS gets close, but doesn't have the data I'm looking for. Can someone help with this point? SELECT TABLE_NAME,COLUMN_NAME,DATA_TYPE FROM INFORMATION_SCHEMA.COLUMNS Secondarily if anyone has any suggestions on additional fields which would be helpful please post.

  • Is it possible to shuffle a 2D matrix while preserving row AND column frequencies?

    - by j_random_hacker
    Suppose I have a 2D array like the following: GACTG AGATA TCCGA Each array element is taken from a small finite set (in my case, DNA nucleotides -- {A, C, G, T}). I would like to randomly shuffle this array somehow while preserving both row and column nucleotide frequencies. Is this possible? Can it be done efficiently? [EDIT]: By this I mean I want to produce a new matrix where each row has the same number of As, Cs, Gs and Ts as the corresponding row of the original matrix, and where each column has the same number of As, Cs, Gs and Ts as the corresponding column of the original matrix. Permuting the rows or columns of the original matrix will not achieve this in general. (E.g. for the example above, the top row has 2 Gs, and 1 each of A, C and T; if this row was swapped with row 2, the top row in the resulting matrix would have 3 As, 1 G and 1 T.) It's simple enough to preserve just column frequencies by shuffling a column at a time, and likewise for rows. But doing this will in general alter the frequencies of the other kind. My thoughts so far: If it's possible to pick 2 rows and 2 columns so that the 4 elements at the corners of this rectangle have the pattern XY YX for some pair of distinct elements X and Y, then replacing these 4 elements with YX XY will maintain both row and column frequencies. In the example at the top, this can be done for (at least) rows 1 and 2 and columns 2 and 5 (whose corners give the 2x2 matrix AG;GA), and for rows 1 and 3 and columns 1 and 4 (whose corners give GT;TG). Clearly this could be repeated a number of times to produce some level of randomisation. Generalising a bit, any "subrectangle" induced by a subset of rows and a subset of columns, in which the frequencies of all rows are the same and the frequencies of all columns are the same, can have both its rows and columns permuted to produce a valid complete rectangle. (Of these, only those subrectangles in which at least 1 element is changed are actually interesting.) Big questions: Are all valid complete matrices reachable by a series of such "subrectangle rearrangements"? I suspect the answer is yes. Are all valid subrectangle rearrangements decomposable into a series of 2x2 swaps? I suspect the answer is no, but I hope it's yes, since that would seem to make it easier to come up with an efficient algorithm. Can some or all of the valid rearrangements be computed efficiently? This question addresses a special case in which the set of possible elements is {0, 1}. The solutions people have come up with there are similar to what I have come up with myself, and are probably usable, but not ideal as they require an arbitrary amount of backtracking to work correctly. Also I'm concerned that only 2x2 swaps are considered. Finally, I would ideally like a solution that can be proven to select a matrix uniformly at random from the set of all matrices having identical row frequencies and column frequencies to the original. I know, I'm asking for a lot :)

  • Create or override Rails Active Record macros (

    - by Jocelyn
    In a Rails app, Active Record creates created_at and updated_at columns thank to macros, (it seems to be also called "magic columns"). See Active Record Migrations I have some questions about that mecanism: Is it possible to override that to get a third column (e.g. deleted_at) ? Is it possible to create a new macro t.publishing that will create publish_up and publish_down columns, for example? And where to code that? Obviously, I know I can add those columns manually, but I wonder how to achieve it with macros. Working on Rails 4.

  • IN SQL operator in R-Shiny

    - by Piyush
    I am taking multiple selection for component as per below code. selectInput("cmpnt", "Choose Component:", choices = as.character(levels(Material_Data()$CMPNT_NM)),multiple = TRUE) But I am trying to write a sql statement as given below, then its not working.

  • Grid View Button Passing Data Via On Click

    - by flyersun
    Hi, I'm pretty new to C# and asp.net so aplogies if this is a really stupid question. I'm using a grid view to display a number of records from a database. Each row has an Edit Button. When the button is clicked I want an ID to be passed back to a funtion in my .cs file. How do I bind the rowID to the Button field? I've tired using a hyper link instead but this doens't seem to work because I'm posting back to the same page which already has a Permanter on the URL. asp.net <asp:GridView ID="gvAddresses" runat="server" onrowcommand="Edit_Row"> <Columns> <asp:ButtonField runat="server" ButtonType="Button" Text="Edit"> </Columns> </asp:GridView> c# int ImplantID = Convert.ToInt32(Request.QueryString["ImplantID"]); Session.Add("ImplantID", ImplantID); List<GetImplantDetails> DataObject = ImplantDetails(ImplantID); System.Data.DataSet DSImplant = new DataSet(); System.Data.DataTable DTImplant = new DataTable("Implant"); DSImplant.Tables.Add(DTImplant); DataColumn ColPostCode = new DataColumn(); ColPostCode.ColumnName = "PostCode"; ColPostCode.DataType = typeof(string); DTImplant.Columns.Add(ColPostCode); DataColumn ColConsigneeName = new DataColumn(); ColConsigneeName.ColumnName = "Consignee Name"; ColConsigneeName.DataType = typeof(string); DTImplant.Columns.Add(ColConsigneeName); DataColumn ColIsPrimaryAddress = new DataColumn(); ColIsPrimaryAddress.ColumnName = "Primary"; ColIsPrimaryAddress.DataType = typeof(int); DTImplant.Columns.Add(ColIsPrimaryAddress); DataColumn ColImplantCustomerDetailsID = new DataColumn(); ColImplantCustomerDetailsID.ColumnName = "Implant ID"; ColImplantCustomerDetailsID.DataType = typeof(int); DTImplant.Columns.Add(ColImplantCustomerDetailsID); foreach (GetImplantDetails Object in DataObject) { DataRow DRImplant = DTImplant.NewRow(); DRImplant["PostCode"] = Object.GetPostCode(); DRImplant["Consignee Name"] = Object.GetConsigneeName(); DRImplant["Primary"] = Object.GetIsPrimaryAddress(); DRImplant["Implant ID"] = Object.GeTImplantCustomerDetailsID(); DTImplant.Rows.Add(DRImplant); <--- this is what I need to be added to the button } gvAddresses.DataSource = DTImplant; gvAddresses.DataBind();

  • Finding center of fingerprints.

    - by an_ant
    If we suppose that every fingerprint is made of concentric curves (ellipses or circles) - and I'm aware of the fact that not every fingerprint is - how can I find center of those concentric curves? Let's take this "ideal" fingerprint and try to find out its center ... My approaches were to try: Find the spectrum through columns/rows of the image and try to find columns/rows that maximize particular band of the spectrum. I thought that column going through the center would have most regular pattern of changing amplitudes - therefore, most recognizible harmonic. My second approach was to try to count the changes of black-and-white also through the columns and rows, and to maximize that amount among rows and columns also. While these methods work to the some extant, with some additional filtering, they fail, when fingerprint is "not ideal as this one is". Can you think of any different approach? Are there standard ways to do it?

  • HTML Table: How to resize data cells when already specified "colspan"?

    - by Jenny
    I have tabular data to display, which has a meaning to both rows and columns. Columns are time blocks, rows are days. A particular datacell is confined to a single day, but can be in multiple time block. To show this, I am using the colspan tag. <div id = "GuideTable"> <table> <tr> <td colspan = 3> </td></tr></table> </div> Or Whatever. I'm trying to apply CSS formating to the entire table, and for changing colors, etc, things are fine, but wanting to have a consistent width is where I am running into problems. Right now, each data cell's width seems tied to the maximum width in its column (everything auto lines up). Some columns are itty bitty, others are huge. I'm trying to make columns consistently sized (even if that means every column is as big as the biggest column needs to be), but setting an individual datacells width (either via css or in the tag itself) is getting me nowhere. I'm thinking maybe the colspan tag is overriding my manual width? If that's the case, how can I change the width of a column as a whole, especially since they aren't explicitly defined? (CAN you explicitly define columns?) Examples of the CSS I'm using: #GuideTable td{ background:#ffffff; border-style: solid; border-width: 1px; width: 100px; }

  • Import data from multiple CSV files to an Excel sheet

    - by Chetan
    I need to import data from 50 similar csv files to a single excel sheet. Is there any way to get only selected columns from each file and put them together in one sheet. Structure of my csv files: A few columns exactly same in all the files. (I want them to be in excel) then one column with same column name but different data which I want to place next to each other with different names in the excel sheet. I do not not want all other remaining columns from csv files. In short, read all csv files, get all the columns which are common to all csv & put in excel sheet. Now, take one column from each file which has the same header but different data and put one after the other in excel sheet with named from the csv file name. Leave remaining rest of the columns. Write excel sheet to a excel file. Initially I thought it can be easily done, but considering my programming skill in learning stage it is way difficult for me. Please help.

  • Determining Best Table Structure for MySQL Performance

    - by Joe Majewski
    I'm working on a browser-based RPG for one of my websites, and right now I'm trying to determine the best way to organize my SQL tables for performance and maintenance. Here's my question: Does the number of columns in an SQL table affect the speed in which it can be queried? I am not a newbie when it comes to PHP or MySQL. I used to develop things with the common goal of getting them to work, but I've recently advanced to the stage where a functional program is not good enough unless it's fast and reliable. Anyways, right now I have a members table that has around 15 columns. It contains information such as the player's username, password, email, logins, page views, etcetera. It doesn't contain any information on the player's progress in the game, however. If I added columns for things such as army size, gold, turns, and whatnot, then it could easily rise to around 40 or 50 total columns. Oh, and my database structure IS normalized. Will a table with 50 columns that gets constantly queried be a bad idea? Should I split it into two tables; one for the user's general information and one for the user's game statistics? I know I could check the query time myself, but I haven't actually created the tables yet and I think I'd be better off with some professional advice on this important decision for my game. Thank you for your time! :)

  • Greatest not null column

    - by Álvaro G. Vicario
    I need to update a row with a formula based on the largest value of two DATETIME columns. I would normally do this: GREATEST(date_one, date_two) However, both columns are allowed to be NULL. I need the greatest date even when the other is NULL (of course, I expect NULL when both are NULL) and GREATEST() returns NULL when one of the columns is NULL. This seems to work: GREATEST(COALESCE(date_one, date_two), COALESCE(date_two, date_one)) But I wonder... am I missing a more straightforward method?

  • SQL Server column level security

    - by user46372
    I think I need some pointers on security in SQL Server. I'm trying to restrict some of our end users from getting access to certain columns (i.e. SSN) on a table. I thought I could just use column level security to restrict access to the columns. That successfully prevented users from accessing the table directly, but I was surprised that they could still get to those columns through a view that accessed that table. I followed the tips here: http://www.mssqltips.com/sqlservertip/2124/filtering-sql-server-columns-using-column-level-permissions/ Those were very helpful, but when I created a view at the end, the intern was able to access that column by default I've read that views are the best way to accomplish this, but I really don't want to go through and change all of the views and the legacy front-end application. I would rather just restrict it once on the table and if a view tries to access that column it would just fail. Is that possible or am I misunderstanding how security works in SQL Server?

  • Splitting values into groups evenly

    - by Paul Knopf
    Let me try to explain the situation the best I can. Lets say I have 3 values 1, 2, 3 I tell an algorithm to split this values into x columns. Lets say x = 2 for clarification. The algorithm determines that the group of values is best put into two columns the following way. 1st column 2nd column --------------------------- 1 3 2 Each column has an even number (totals, not literals) value. Now lets say I have the following values 7, 8, 3, 1, 4 I tell the algorithm that I want the values split into 3 columns. The algorithm now tells me that the following is the best fit. 1st column 2nd column 3rd column 8 7 3 1 4 Notice how the columns arent quiet even, but it is as close as it can get. A little over and a little under is considered ok, as long as the list is AS CLOSE TO EVEN AS IT CAN BE. Anybody got any suggestions? Know any good methods of doing this?
