  • Remove specific string from multiple database rows in SQL

    - by Scott
    I have a column that contains page titles, which has the website name appended to the end of each. (e.g. Product Name | Company Name Inc.) I would like to remove the " | Company Name Inc." from multiple rows simultaneously. What SQl query commands (or query itself) would allow me to accomplish this? To re-illustrate, I want to convert multiple rows of 1 column from this: Product Name | Company Name Inc. To this: Product Name

  • putting data from a for loop into a table using matlab and fprintf

    - by user2928537
    I am trying to put the following data from my for loop into a table formatted so that there are 11 values of F in each column, with a total of 4 columns. but I am always ending up with one long column of my data instead of the four columns I want. I was wondering if there is some way to put the data into a matrix and then reshape it, but I am having trouble. Any help greatly appreciated. fprintf ('Electrostatic Forces:\n') for r = 1:4; q2 = 0: 1*10^-19: 1*10^-18; for F = coulomb(q2,r); fprintf ('%d\n',F) end end Where the code for the function coulomb is function F = coulomb (q2,r); k = 8.98*10^9; q1 = 1.6*10^-19; F = k*abs(q1*q2)/r^2; end

  • How to achieve jQuery scrolling/overlay effect (video in description)

    - by waffl
    I have two columns. The left column contains text of dynamic lengths. The right column is of fixed height and will contain a set of images selected at random per page load. I am trying to create an effect where while the user scrolls, the Image 2 scrolls above Image 1. When it reaches the top, the Image 1 begins to scroll up until it disappears, then Image 3 comes in and repeats the process. As this is rather confusing, I made a short video describing the desired effect. Video - MP4 I have begun trying to get it working in this jsbin but am at a loss for when the user scrolls back down and also when more images are required. I am thinking my current path is not the right direction. I'm thinking that employing something like jQuery waypoints is more the direction I should be pursuing?

  • MySQL Query to receive random combinations from two tables.

    - by Michael
    Alright, here is my issue, I have two tables, one named firstnames and the other named lastnames. What I am trying to do here is to find 100 of the possible combinations from these names for test data. The firstnames table has 5494 entries in a single column, and the lastnames table has 88799 entries in a single column. The only query that I have been able to come up with that has some results is: select * from (select * from firstnames order by rand()) f LEFT JOIN (select * from lastnames order by rand()) l on 1=1 limit 10; The problem with this code is that it selects 1 firstname and gives every lastname that could go with it. While this is plausible, I will have to set the limit to 500000000 in order to get all the combinations possible without having only 20 first names(and I'd rather not kill my server). However, I only need 100 random generations of entries for test data, and I will not be able to get that with this code. Can anyone please give me any advice?

  • TDBGrid columns design time or run time?

    - by Mawg
    I am using TDBGrid for the first time. I didn't even notice the Columns property in the object inspector and everything went just fine: the grid was filled. Then I saw the Columns property and tried it. When I use the object insector to add items to the Columns property of the grid, they do not all of them show up at run time. To me, it looks like the FieldName property is important. It looks like it is correct, but there are no values in some columns. If I leave this property blank (no columns at all) it seems that the control populates it itself at run time and I do see all the columns. I could live with that. When I set column titles at run time it works, but setting column width does not.

  • Can I bypass an intermediate object in hibernate

    - by Jherico
    I have top level entities TRACK, MEDIA_GROUP and MEDIA, each with an integer primary key. I also have a join table from TRACK to MEDIA_GROUP which is 1:1 and MEDIA has a FK column into MEDIA_GROUP. I'm trying to find a way in hibernate to map a collection of Media directly into the Track object, bypassing the creation of a MediaGroup object. Basically I want to turn this: TRACK <-> MEDIA_TRACK_MAP <-> MEDIA_GROUP <-> MEDIA into this: TRACK <-> MEDIA_TRACK_MAP <-> MEDIA But the join column between MEDIA_TRACK_MAP and MEDIA isn't the primary key of MEDIA.

  • How to localize numerals?

    - by SoLoGHoST
    Ok, I'm using mathematical equations to output numbers, though, I need this to be compatible for all languages. Currently, all language strings are within a php array called $txt, and each key of the array gets called for that language. I'm outputting the following: Column 1, Column 2, Column 3, and so on, as well as Row 1, Row 2, Row 3, and so on. The calculations are done via php and javascript, so I'm wondering on the best approach for how to support all languages for the numbers only. I don't do the translations, someone else does, but I need to be able to point it to, either the php variable $txt of where the language is defined, or, since the calculations are done via javascript also, I need to somehow store this in there. I'm thinking of storing something like this: // This part goes in the php language file. $txt['0'] = '0'; $txt['1'] = '1'; $txt['2'] = '2'; $txt['2'] = '3'; $txt['4'] = '4'; $txt['5'] = '5'; $txt['6'] = '6'; $txt['7'] = '7'; $txt['8'] = '8'; $txt['9'] = '9'; // This part goes in the php file that needs to call the numbers. echo '<script> var numtxts = new Array(); numtxts[0] = \'', $txt['0'], '\'; numtxts[1] = \'', $txt['1'], '\'; numtxts[2] = \'', $txt['2'], '\'; numtxts[3] = \'', $txt['3'], '\'; numtxts[4] = \'', $txt['4'], '\'; numtxts[5] = \'', $txt['5'], '\'; numtxts[6] = \'', $txt['6'], '\'; numtxts[7] = \'', $txt['7'], '\'; numtxts[8] = \'', $txt['8'], '\'; numtxts[9] = \'', $txt['9'], '\'; </script>'; And than in the javascript function it could grab the correct string for each number like so: // Example Number String below. var numString = "10"; var transNum = ""; for(x=0;x<numString.length;x++) { var numChar = numString.charAt(x); transNum += numtxts[parseInt(numChar)]; } return transNum; The problem with this bit of code is that it groups the numbers, not sure if all languages do that, like the english language does...? Perhaps there's a better approach for this? Can anyone help please? Thanks :)

  • SQL update statement to change the value of a field and not replace it

    - by wzzrd
    I'm in the process of migrating some databases. I have this table that has a couple of hundred rows, and has a filename column. To each record in this table, the filename column needs to be altered and part of a path needs to be prepended to the value that is in that field. The table is like: | 1 | filename1 | | 2 | filename2 | and needs to become: | 1 | path/filename1 | | 2 | path/filename2 | I am not an SQL guru, but I know the basics. This eludes me though. Is there a way to do something like: update table set filename = 'path/' + filename where id = 1;

  • Rails creating and updating 2 model records simultaneously

    - by LearnRails
    I have 2 tables product and history product table id name type price location 1 abc electronics $200 aisle1 history table id product_id status 1 1 price changed from $200 to $180 Whenever the product price or location is updated by a user by hitting the update button, 1) the changes should be automatically be reflected in the history status column without the user having to enter that manually. if the price is updated from 200 to 180 then a new history row will be created with new id and the status column will say ' price changed from $200 to $180' if the location is updated from aisle1 to aisle 2 then status displays ' loc changed from ailse1 to aisle 2' I tried to @product = Product.new(params[:product]) @history= History.new(params[:history]) if @product.save @history.new(attributes) == I am not sure of whether this approach is correct I would really appreciate if someone could tell me how the history can be automatically updated in this case.

  • How do I specify a default value in a MS Access query?

    - by jheddings
    I have three tables similar to the following: tblInvoices: Number | Date | Customer tblInvDetails: Invoice | Quantity | Rate | Description tblPayments: Invoice | Date | Amount I have created a query called exInvDetails that adds an Amount column to tblInvDetails: SELECT tblInvDetails.*, [tblInvDetails.Quantity]*[tblInvDetails.Rate]* AS Amount FROM tblInvDetails; I then created a query exInvoices to add Total and Balance columns to tblInvoices: SELECT tblInvoices.*, (SELECT Sum(exInvDetails.Amount) FROM exInvDetails WHERE exInvDetails.Invoice = tblInvoices.Number) AS Total, (SELECT Sum(tblPayments.Amount) FROM tblPayments WHERE tblPayments.Invoice = tblInvoices.Number) AS Payments, (Total-Payments) AS Balance FROM tblInvoices; If there are no corresponding payments in tblPayments, the fields are null instead of 0. Is there a way to force the resulting query to put a 0 in this column?

  • How to get the right row in a sorted DataView?

    - by ZeissS
    Hi, I have a DataGrid containing a small table. Until now, I had a double click handler on this grid which iterated over all rows to find the selected one: DataTable table = (DataTable)this.dataGrid.DataSource; int selectedRow = -1; for (int i=0; i<table.Rows.Count; i++) if (this.dataGrid.IsSelected(i)) selectedRow = i; break; } if ( selectedRow != -1 ) { DataRow row = table.Rows[selectedRow]; // More code ... } Problem: When the user clicks on a column header and sort the table, table.Rows does not return the right rows. It still contains the unsorted rows. How can I get the right column?

  • Find and sort by number of ocurrences of tag with Active Admin and act_as_taggable_on

    - by nunopolonia
    I'm using act_as_taggable_on and Active Admin on a Rails project. In that project there are Posts and each Post has Tags. I want to show a list of Tags in Active Admin and the number of ocurrences of each one. The way I found to do this was: index do column :name column :ocurrences do |tag| ocurrences = Post.tag_counts.find(tag.id).count end default_actions end Which will search the Tag List every time for every Post, which performance wise looks really bad. I would also like to be able to sort the tags by ocurrence. Any idea of how I can do it?

Anyone know how to create an indexed view using aliased columns please let me know.

  • How do I specify a dynamic position for the start of substring?

    - by analyticsPierce
    As in the example, I am trying to substring the Video_full column in a data.frame (video_data_2) I am working on. I want to keep all the characters after the period. The period is always present, there is only one period and it is in a different position in each value for the column. Date Video_full Instances 1 Apr 1, 2010 installs/AA.intro_video_1 546 2 Apr 1, 2010 installs/ABAC.intro_video_2 548 I got substring to work; video_data_2$Video_full <- substring(video_data_2$Video_full,11) And strsplit also; strsplit("installs/AA.intro_video_1 ",'[.]') I'm just not able to figure out how to start the substring in a dynamic position or only keep the second value returned by strsplit. Thanks for any help you can offer for a simple question.

  • How to split row into multiple rows from the MySQL?

    - by user2818537
    I have a MySQL data table, in which I have more than 2 columns. First column has a unique value clinical trial value whereas second column has disease information. There are, in most of the cases, more than 2 disease names in one cell for a single id. I want to spilt those rows which cell contains two or more than two diseases. There is a pattern for searching also, i.e. small character is immediately followed by capital character., e.g. MalariaDengueTuberculosis like this. Suppose for these three diseases there is unique id, it should show like the following: NCT-ID disease 4534343654 Maleria 4534343654 Dengue 4534343654 Tubercoulsosis

  • Trying to get unique records with MySQL

    - by Joshmattvander
    I have a query that is looking at a 'page_views' table. And I so far have the ability to get the total views by day. However, I am having an issue with getting unique views by day. The column I am testing against is user_id... Here's the query I have for total views. SELECT site_id, CONCAT(month(created_at) , '-', day(created_at), '-' , year(created_at)) as created_at_date, COUNT(*) as total_results FROM page_views GROUP BY day(created_at) I can't figure out the logic to just get the unique views, by day based on the user_id column though.

  • Getting time from a cell in Google Spreadsheet

    - by lostInTransit
    Hi I have created a Google Spreadsheet form in which for one of the fields I get the time (hh:mm:ss) in 24-hour format. I am using Google Apps Scripts to read values from this spreadsheet and put it into another file. But the other file gets the entire date (don't know from where) and shows a date from 1899. Also the time is shown in PDT (not my time zone). Even the time it prints is not correct How do I read the column value as a string and put it in the other file OR get just the time from the column value (and the correct time) I am using a simple row[0][3] to get the values from an array after doing range.getValues() Thanks.

  • How can I ask Hibernate to create an index on a foreign key (JoinColumn)?

    - by Kent Chen
    Hi, This is my model. class User{ @CollectionOfElements @JoinTable(name = "user_type", joinColumns = @JoinColumn(name = "user_id")) @Column(name = "type", nullable = false) private List<String> types = new ArrayList<String>(); } You can imagin there would be a table called "user_type", which has two columns, one is "user_id", the other is "type". And when I use hbm2ddl to generate the ddls, I can have this table, along with the foreign key constraint on "user_id". However, there is no index of this for this column. And I need this index. How can I let hibernate to generate this index for me? Thank you!
