  • How to match data between columns to do the comparasion

    - by NCC
    I do not really know how to explain this in a clear manner. Please see attached image I have a table with 4 different columns, 2 are identical to each other (NAME and QTY). The goal is to compare the differences between the QTY, however, in order to do it. I must: 1. sort the data 2. match the data item by item This is not a big deal with small table but with 10 thousand rows, it takes me a few days to do it. Pleas help me, I appreciate. My logic is: 1. Sorted the first two columns (NAME and QTY) 2. For each value of second two columns (NAME and QTY), check if it match with first two column. If true, the insert the value. 3. For values are not matched, insert to new rows with offset from the rows that are in first two columns but not in second two columns

  • How to design a database where the main entity table has 25+ columns but a single entity's columns g

    - by thenextwebguy
    The entities to be stored have 25+ properties (table columns). The entities are pretty diverse, meaning that, most of the columns are empty. On average, I'd say, less than 20% (<5) properties have a value in any particular item. So, I have a lot of redundant empty columns for most of the table rows. Almost all of the columns are decimal numbers. Given this scenario, would you suggest serializing the columns instead, or perhaps, create another table named "Property", which would contain all the possible properties and then creating yet another table "EntityProperty" which would map an property to an entity using foreign keys? Or would you leave it as it is?

  • Filtering columns in SQL Server replication - how?

    - by truthseeker
    Hi, I need to replicate some data from two tables in one database to another databases. I used snapshot replication. The issue is that I would like to replicate only some selected columns and the others should stay with untouched data. I don't want to loose their data. The sours of those columns is other system. So I need to replicate only data from my columns. Do anybody know how to achieve this?

  • Multiple columns in a single index versus multiple indexes

    - by Tim Coker
    The short version of my question is what's the difference between three indexes each indexing a single column and one index indexing three columns. Background follows. I'm primarily a programmer but have to do DBA work because we don't have a DBA. I'm evaluating our indexes versus the queries run against a particular table. The table as 3 columns that I'm often filtering against or getting the max value of. Most of the time the queries look like select max(col_a) from table where col_b = 'avalue' or select col_c from table where col_b = 'avalue' and col_a = 'anothervalue' All columns are independently indexed. My question is would I see any difference if I had an index that indexed col_b and col_a together since they can appear in a where clause together?

  • calculate next line numbers

    - by osomanden
    Weird question I guess.. But I am not very math wiz - soo here goes.. I am trying to create a patterne (or variable patterns based on selection) based on x and y numbers (2 rows and 4 columns) and the direction of the counting of x numbers like: 1-2-3-4 5-6-7-8 That one is easy, when number of x-columns is reached, next line and continue x count. But with eg. this one (still 2 rows and 4 columns): 1-2-3-4 8-7-6-5 upsie.. what if it is eg. 3++ rows and still 4 columns? 1-2-3-4 8-7-6-5 9-10-11-12 what would be the formula for this - or other possible variations (teaser for variations): 9-10-11-12 8-7-6-5 1-2-3-4 or reversed

  • R: convert data.frame columns from factors to characters

    - by Mike Dewar
    Hi, I have a data frame. Let's call him bob: > head(bob) phenotype exclusion GSM399350 3- 4- 8- 25- 44+ 11b- 11c- 19- NK1.1- Gr1- TER119- GSM399351 3- 4- 8- 25- 44+ 11b- 11c- 19- NK1.1- Gr1- TER119- GSM399352 3- 4- 8- 25- 44+ 11b- 11c- 19- NK1.1- Gr1- TER119- GSM399353 3- 4- 8- 25+ 44+ 11b- 11c- 19- NK1.1- Gr1- TER119- GSM399354 3- 4- 8- 25+ 44+ 11b- 11c- 19- NK1.1- Gr1- TER119- GSM399355 3- 4- 8- 25+ 44+ 11b- 11c- 19- NK1.1- Gr1- TER119- I'd like to concatenate the rows of this data frame (this will be another question). But look: > class(bob$phenotype) [1] "factor" Bob's columns are factors. So, for example: > as.character(head(bob)) [1] "c(3, 3, 3, 6, 6, 6)" "c(3, 3, 3, 3, 3, 3)" [3] "c(29, 29, 29, 30, 30, 30)" I don't begin to understand this, but I guess these are indices into the levels of the factors of the columns (of the court of king caractacus) of bob? Not what I need. Strangely I can go through the columns of bob by hand, and do bob$phenotype <- as.character(bob$phenotype) which works fine. And, after some typing, I can get a data.frame whose columns are characters rather than factors. So my question is: how can I do this automatically? How do I convert a data.frame with factor columns into a data.frame with character columns without having to manually go through each column? Bonus question: why does the manual approach work?

  • making html table columns optionally sortable

    - by jdamae
    I have an html table that is populated from a text file, formatted and semi colon separated. I would like the user to have the option of sorting alphabetically with either of the columns when clicking on the column name (header). How do I do this in php?? Or is there another way of doing this? Thanks for your help. Sample raw data/input looks like this: TYPE=abc;PART=georgetown;FILE=goog_abc.dat.2010122211.gz TYPE=xyz;PART=ucny;FILE=aol_xyz.dat.2010122209.gz Php code for table: $lines = preg_split('~\s*[\r\n]+\s*~', file_get_contents('/temp/tab.txt')); foreach($lines as $i => $line) { $pairs = explode(';', $line); foreach($pairs as $pair) { list($column, $value) = explode('=', $pair, 2); $columns[$column] = true; $rows[$i][$column] = $value; } } $columns = array_keys($columns); echo '<table><thead><tr>'; foreach($columns as $column) { echo '<th>'.$column.'</th>'; } echo '</tr></thead><tbody>'; foreach ($rows as $row) { echo '<tr>'; foreach($columns as $column){ echo '<td>'.$row[$column].'</td>'; } echo '</tr>'; } echo '</tbody></table>';

  • Uniform grid Rows and Columns

    - by Carlo
    I'm trying to make a grid based on a UniformGrid to show the coordinates of each cell, and I want to show the values on the X and Y axes like so: _A_ _B_ _C_ _D_ 1 |___|___|___|___| 2 |___|___|___|___| 3 |___|___|___|___| 4 |___|___|___|___| Anyway, in order to do that I need to know the number of columns and rows in the Uniform grid, and I tried overriding the 3 most basic methods where the arrangement / drawing happens, but the columns and rows in there are 0, even though I have some controls in my grid. What method can I override so my Cartesian grid knows how many columns and rows it has? C#: public class CartesianGrid : UniformGrid { protected override Size MeasureOverride(Size constraint) { Size size = base.MeasureOverride(constraint); int computedColumns = this.Columns; // always 0 int computedRows = this.Rows; // always 0 return size; } protected override Size ArrangeOverride(Size arrangeSize) { Size size = base.ArrangeOverride(arrangeSize); int computedColumns = this.Columns; // always 0 int computedRows = this.Rows; // always 0 return size; } protected override void OnRender(DrawingContext dc) { int computedColumns = this.Columns; // always 0 int computedRows = this.Rows; // always 0 base.OnRender(dc); } } XAML: <local:CartesianGrid> <Label Content="Hello" /> <Label Content="Hello" /> <Label Content="Hello" /> <Label Content="Hello" /> <Label Content="Hello" /> <Label Content="Hello" /> </local:CartesianGrid> Any help is greatly appreciated. Thanks!

  • Reordering columns (fields) in a ADO Recordset

    - by Sukotto
    I have a classic asp webpage written in vbscript that outputs the results from a third-party stored procedure. My user wants the page to display the columns of data in a different order than they come in from the database. Is there an easy and safe way to re-order the columns in an ADO recordset? I did not write this page and cannot change the SP. What is the minimum change I can make here to get the job done and not risk screwing up all the other stuff in the page? The code looks something like dim Conn, strSQL, RS Set Conn = Server.CreateObject("ADODB.Connection") Conn.Open ServerName Set strSQL = "EXEC storedProc @foo = " & Request("fooParam") 'This stored procedure returns a date column, an arbitrary ' ' number of data columns, and two summation columns. We ' ' want the two summation columns to move so they appear ' ' immediately after the data column ' Set RS = Server.CreateObject("ADODB.RecordSet") RS.ActiveConnection = Nothing RS.CursorLocation = adUseClient RS.CursorType = adOpenStatic RS.LockType = adLockBatchOptimistic RS.Open strSQL, Conn, adOpenDynamic, adLockOptimistic dim A ' ----- ' ' Insert some code here to move the columns of the RS around ' ' to suit the whim of my user ' ' ----- ' ' Several blocks of code that iterate over the RS and display it various ways ' RS.MoveFirst For A = 0 To RS.Fields.Count -1 ' do stuff ' Next ... RS.MoveFirst For A = 0 To RS.Fields.Count -1 ' do more stuff ' Next RS.Close : Set RS = Nothing Conn.Close : Set Conn = Nothing

  • How to columnate text with tabs (in vim or on the shell)

    - by kine
    I have a frequent need to manually manipulate tab-delimited text for data entry and other purposes, and when i do this it helps if the text is aligned properly into columns. For example (assuming 4-space tabs): # original format abcdefghijklmnop field2 abcdefgh field2 abcdefghijkl field2 # ideal format abcdefghijklmnop field2 abcdefgh field2 abcdefghijkl field2 I am very familiar with using the column utility to columnate text this way, but the problem is that it uses spaces to align the columns, and i specifically need tabs. This requirement also appears to rule out the Tabularize plug-in. Is there any way that i can columnate text with tabs specifically, either within vim or at the shell? It looks like i might be able to do it with groff/tbl, but honestly i'd rather columnate it by hand than mess with that....

  • Dynamic DataGrid columns in WPF DataGrid based on the underlying set of data (and their type)

    - by StatsMan
    Hello everyone, I've got kind of a conceptual question. I am in the process of wrapping some statistics classes I wrote into WPF. For that I have two DataGrid(-Views, currently in WinForms). In one DataGrid each row represents a column in the other. There I can set-up different variables (as in mathematical/statistical variables) with fields like "Header", "DataType", "ValidationBehaviour", "DisplayType". There I can also set-up how it should be displayed. Some Columns can automatically be set to ComboBoxColumns, some TextBoxColumns, and so on and so forth. So, now once I've set-up these Columns I can go to the other grid and enter my data. I may, for instance, have generated (in grid 1) one Column called "Annual Gross Salary" with input of numerical values. Another Column called "Education" with "0=NoEducation", "1=College Level", "3=Universitary" etc. These labels are displayed as text in the combobox and my statistics engine behind then selects the respective value (0-3) for calculations (i.e. ordinal, nominal variables). Sooo. In WinForms I could basically generate all the columns by hand in code and then add my data in the respective cells/rows. Now in WPF I thought that must be easy to realise. However, yesterday I got started with ICustomPropertyDescriptor which (maybe I was too thick) didn't give me the results I was looking for. Basically, I just need to be able to dynamically generate columns (and rows) with different Layout, Controls (ComboBox, simple Input, DateTimes) based on the data that I have. But I don't really know how to go about it? So here in summary: DataGrid 1 Purpose is to display columns that have been specified in DataGrid 2 In rows, the user can add any kind of data in the rows below the columns that is allowed as to the columns specifications DataGrid 2 Each row in this grid represents a column in DataGrid 1 Contains fields like Name/Header, DataType, Validation Behaviour, Default Value, Data Formatting, etc. Also contains a function to be able to set-up how it should be displayed. The user can select from, for instance, ComboBoxColumn (and also add the available options), DateTime, normal TextBox, CheckBox etc. After finishing adding a row it will automatically appear as a new column in DataGrid 1 I'd appreciate any kind of pointer into the right direction. Thanks very, very much in advance! :)

  • Create or Open an .xlsx file having >256 columns in MS Excel 2003

    - by Daredev
    I'm using Microsoft Office 2003. I have installed 'Microsoft Office Compatibility Pack for Word, Excel, Powerpoint 2007' to support new xml based formats (.docx, .xlsx, .pptx). Now given that I have installed Compatibility pack, can I create or open a Microsoft Excel 2007 file (.xlsx) having more than 256 columns in Excel 2003? If no, then how can I achieve the same. My observation: When I open a .xlsx file in Excel 2003 with compatibility, I can't see more than 256 columns (till Column IV).

  • Results copied from SSMS splitting across columns when pasted into Excel

    - by adolf garlic
    SSMS 2008 - Excel 2003 This isn't happening all the time, but sometimes when I 'copy with headers' from sql server management studio, the results in Excel look as though I've used the 'text to columns' wizard with 'spaces' and 'brackets' as delimiters, meaning that the results become raggedly distributed across columns making them useless I've looked in the 'grid output' query options but can't see anything which may be causing the issue (not sure if this should be on superuser?)

  • Moving Data from One Column into Six Columns

    - by Alex Rudd
    I have an Excel sheet that has six columns that are currently all combined into one column. I need to separate them out but the issue is the first column is words that sometimes are one word and sometimes two. Here is an example: Twin 70 442 186 310 221 Twin Futon 70 389 160 272 195 XL twin 70 463 196 324 231 XL Twin Futon 70 418 174 293 209 Double 100 590 245 413 295 How can I separate these data sets while keeping the words all in the same columns?

  • SharePoint - Summing Calculated Columns By Groups (DVWP)

    - by Mark Rackley
    I had a problem… okay.. okay.. so I have many problems… but let’s focus on one in particular or this blog post would never end… okay? Thank you…. So, I had an electronic timesheet where users entered hours for each day of the week. It also had a “Week Total” column which was a calculated column of the sum. The calculated column looked like this: Pretty easy.. nothing spectacular. So, what’s the problem? WELL……………….. There is a row in the timesheet for each task a person worked on in a given week. So, if you worked on 4 tasks, you would have 4 rows of data, and 4 week totals for that week: This is all fine and dandy, but I want to know what the total was for the entire week. Yes.. I realize the answer is 24 from my example… I mean, I know how to add! I just want SharePoint to display it for me for the executives (we all know, they have math problems).  You may be thinking, hey genius (in a sarcastic tone of course), why don’t you just go to the view and total on the “Week Total” field. What a brilliant idea! Why didn’t I think of that… let’s go to the view and do just that…. Ohhhhhh… you can’t total on a Calculated Column.. it’s not even an option…  Yeah… I had the same moment. So, what do you do? Well… what do you think I did? 1) Googled “SharePoint total calculated column” 2) Said it couldn’t be done 3) Took a nap 4) Asked the question on twitter? The correct answer of course is number 4… followed by number 3… although I may have told my boss number 2 so that I look more brilliant than I am? It’s safe to say I did NOT try to find the solution on my own doing step 1… that would be just WAY to easy… So, anyway, I posted the question on Twitter and it turns out several people had suggestions from using jQuery to using DVWPs. I tend to be a big fan of the DVWP except for the disgusting process of deploying them to another farm.. ugh… just shoot me…. so, that is the solution I went with. Laura Rogers (@WonderLaura) has a super duper easy to follow video on the subject over at EndUserSharePoint.com: SharePoint: Displaying Calculated Column SUMS in a View (Screencast) Laura’s video was very easy to follow and was ALMOST exactly what I needed. She does a great job walking you through every step of summing up a calculated field which was PART of my problem. The other part was my list is grouped by date! So, I wanted to see for a given week, the summed “Week Total” of hours. Laura got me on the right track with her video and I dug a little deeper into the DVWP to accomplish my task. So, here are the steps you follow: 1. Click on the "chevron” (I didn’t know it was actually called that until I heard Laura say it).. I always call it the “little-button-in-the-top-right-corner-with-the-greater-than-sign”.. but “chevron” is much shorter. So, click on the chevron, click on “Sort and Group”. The Add the field you want to group by, in my example it is the “Monday Date” of the timesheet entry. Make sure to check the check boxes for “Show Group Header” AND “Show Group Footer”. Click “OK”. The view now shows the count of each grouped set of data: Interesting, this looks very similar to Laura’s video… right? So, let’s take a look at the code for the Count: Count : <xsl:value-of select="count($nodeset)" /> Wow, also very similar… except in Laura’s video it looks like: Count : <xsl:value-of select="count($Rows)" /> So.. the only difference is that instead of $Rows we have $nodeset. It turns out the $nodeset will go through each Row in the group just like $Rows goes through each row in the entire view. So, using the exact same logic as in Laura’s blog except replacing $Rows with $nodeset we get the functionality of being able to sum up the values for a group. So, I want to replace “Count: #” with the total hours, this is done using the following changes to the above code: Week Total : <xsl:value-of select="sum($nodeset/@Monday)+sum($nodeset/@Tuesday) +sum($nodeset/@Wednesday)+sum($nodeset/@Thursday)+sum($nodeset/@Friday) +sum($nodeset/@Saturday)+sum($nodeset/@Sunday)" /> Our final output has the summed hours for each group! So… long story short… follow Laura’s blog, then group your list, then replace “$Rows” with “$nodeset”. One caveat, this will not work if you group by a person field. For some reason the person field does not go through each row in the group. I haven’t dug into this much yet. Maybe if I find some time… whatever that is… Anyway, Laura did all the work, I just took it one small step forward… as always, feel free to leave any additional insights you may have. We’re all learning here!

  • dependency analysis from C# code thru to database tables/columns

    - by fpdave
    I'm looking for a tool to do system wide dependency analysis in C# code and SQL-Server databases. Its looking like the only tool available that does this might be CAST (cast software), which is expensive and it does lots more besides that I dont really need. c# code thru to database column dependency would be hugely useful for many reasons, including: - determining effects of database changes throughout the system - seeing hot spots in the database schema - finding dead stored procedures/tables/etc - understanding the existing code base does anyone know of any such tools?

  • SQL SERVER – Grouping by Multiple Columns to Single Column as A String

    - by pinaldave
    One of the most common questions I receive in email is how to group multiple column data in comma separate values in a single row grouping by another column. I have previously blogged about it in following two blog posts. However, both aren’t addressing the following exact problem. Comma Separated Values (CSV) from Table Column Comma Separated Values (CSV) from Table Column – Part 2 The question comes in many different formats but in following image I am demonstrating the same question in simple words. This is the most popular question on my Facebook page as well. (Example) Here is the sample script to build the sample dataset. CREATE TABLE TestTable (ID INT, Col VARCHAR(4)) GO INSERT INTO TestTable (ID, Col) SELECT 1, 'A' UNION ALL SELECT 1, 'B' UNION ALL SELECT 1, 'C' UNION ALL SELECT 2, 'A' UNION ALL SELECT 2, 'B' UNION ALL SELECT 2, 'C' UNION ALL SELECT 2, 'D' UNION ALL SELECT 2, 'E' GO SELECT * FROM TestTable GO Here is the solution which will build an answer to the above question. -- Get CSV values SELECT t.ID, STUFF( (SELECT ',' + s.Col FROM TestTable s WHERE s.ID = t.ID FOR XML PATH('')),1,1,'') AS CSV FROM TestTable AS t GROUP BY t.ID GO I hope this is an easy solution. I am going to point to this blog post in the future for all the similar questions. Final Clean Up Act -- Clean up DROP TABLE TestTable GO Here is the question back to you - Is there any better way to write above script? Please leave a comment and I will write a separate blog post with due credit.

  • Better way to search for text in two columns

    - by David
    Here is the scenario. I am making a custom blogging software for my site. I am implementing a search feature. It's not very sophisticated - basically it just takes the search phrase entered and runs this query: $query="SELECT * FROM `blog` WHERE `title` LIKE '%$q%' OR `post` LIKE '%$q%'"; Which is meant to simply search the title and post body for the phrase entered. Is there a better way to do that, keeping in mind how long it would take to run the query on up to 100 rows, each with a post length of up to 1500 characters? I have considered using a LIMIT statement to (sometimes) restrict the number of rows that the query would examine. Good idea?
