  • I Need Help Fixing My Small Time Sheet Table - Relational DB - SQL Server

    - by user327387
    I have a TimeSheet table as: CREATE TABLE TimeSheet ( timeSheetID employeeID setDate timeIn outToLunch returnFromLunch timeOut ); Employee will set his/her time sheet daily, i want to ensure that he/she doesn't cheat. What should i do? Should i create a column that gets date/time of the system when insertion/update happens to the table and then compare the created date/time with the time employee's specified - If so in this case i will have to create date/time column for timeIn, outToLunch, returnFromLunch and timeOut. I don't know, what do you suggest? Note: i'm concerned about tracking these 4 columns timeIn, outToLunch, returnFromLunch and timeOut

  • Making fscanf Ignore Optional Parameter

    - by adi92
    I am using fscanf to read a file which has lines like Number <-whitespace- string <-whitespace- optional_3rd_column I wish to extract the number and string out of each column, but ignore the 3rd_column if it exists Example Data: 12 foo something 03 bar 24 something #randomcomment I would want to extract 12,foo; 03,bar; 24, something while ignoring "something" and "#randomcomment" I currently have something like while(scanf("%d %s %*s",&num,&word)>=2) { assign stuff } However this does not work with lines with no 3rd column. How can I make it ignore everything after the 2nd string?

  • Differences between extension methods in C#3 & 4

    - by Buh Buh
    I think I remember reading a long time ago that in C#3 extension methods could only be applied to primitive types and interfaces; and that in C#4 they could be used to extend any type. This doesn't seam to match up with what I am seeing now and I am finding it difficult to find this documented. Is there any truth to this or did my memory make it all up? What are the rules relating to which types can be extended? Are there any differences between C# 3 and 4?

  • Proper use of use of "cor" function in R

    - by order
    I am interested to know what a proper x (vector matrix or data frame) input looks like. I am currently using the function in two different sorts of matrices. However, I am not sure how R would interpret my data the way I intend. I will explain the types of matrix by example. Type 1 Gene1 Gene2 Gene3 sample1 sample2 Type 2 Sample1 Sample2 Sample3 gene 1 gene 2 gene 3 Are either of these formats valid x parameters? I input both of types of matrices and get some results, but without knowing whether or not this a proper use the function, these are just random numbers. Thank you for your time. I apologize that this isn't more interesting.

  • Determining child count of path

    - by sqlnewbie
    I have a table whose 'path' column has values and I would like to update the table's 'child_count' column so that I get the following output. path | child_count --------+------------- | 5 /a | 3 /a/a | 0 /a/b | 1 /a/b/c | 0 /b | 0 My present solution - which is way too inefficient - uses a stored procedure as follows: CREATE FUNCTION child_count() RETURNS VOID AS $$ DECLARE parent VARCHAR; BEGIN FOR parent IN SELECT path FROM my_table LOOP DECLARE tokens VARCHAR[] := REGEXP_SPLIT_TO_ARRAY(parent, '/'); str VARCHAR := ''; BEGIN FOR i IN 2..ARRAY_LENGTH(tokens, 1) LOOP UPDATE my_table SET child_count = child_count + 1 WHERE path = str; str := str || '/' || tokens[i]; END LOOP; END; END LOOP; END; $$ LANGUAGE plpgsql; Anyone knows of a single UPDATE statement that does the same thing?

  • 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

  • get n records at a time from a temporary table

    - by Claudiu
    I have a temporary table with about 1 million entries. The temporary table stores the result of a larger query. I want to process these records 1000 at a time, for example. What's the best way to set up queries such that I get the first 1000 rows, then the next 1000, etc.? They are not inherently ordered, but the temporary table just has one column with an ID, so I can order it if necessary. I was thinking of creating an extra column with the temporary table to number all the rows, something like: CREATE TEMP TABLE tmptmp AS SELECT ##autonumber somehow##, id FROM .... --complicated query then I can do: SELECT * FROM tmptmp WHERE autonumber>=0 AND autonumber < 1000 etc... how would I actually accomplish this? Or is there a better way? I'm using Python and PostgreSQL.

  • How do I guarantee row uniqueness in MySQL without the use of a UNIQUE constraint?

    - by MalcomTucker
    Hi I have some fairly simple requirements but I'm not sure how I implement them: I have multiple concurrent threads running the same query The query supplies a 'string' value - if it exists in the table, the query should return the id of the matching row, if not the query should insert the 'string' value and return the last inserted id The 'string' column is (and must be) a text column (it's bigger than varchar 255) so I cannot set it as unique - uniqueness must be enforced through the access mechanism The query needs to be in stored procedure format (which doesnt support table locks in MySQL) How can I guarantee that 'string' is unique? How can I prevent other threads writing to the table after another thread has read it and found no matching 'string' item? Thanks for any advice..

  • Partially parse C++ for a domain-specific language

    - by PierreBdR
    I would like to create a domain specific language as an augmented-C++ language. I will need mostly two types of contructs: Top-level constructs for specialized types or declarations In-code constructs, i.e. to add primitives to make functions calls or idiom easier The language will be used for scientific computing purposes, and will ultimately be translated into plain C++. C++ has been chosen as it seems to offer a good compromise between: ease of use, efficiency and availability of a wide range of libraries. A previous attempt using flex and bison failed due to the complexity of the C++ syntax. The existing parser can still fail on some constructs. So we want to start over, but on better bases. Do you know about similar projects? And if you attempted to do so, what tools would you use? What would be the main pitfalls? Would you have recommendations in term of syntax?

  • 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?

  • How do I transform a single colmn list to item matrix in R?

    - by Indy
    I currently have data that is in the following format (note, this is 1 column, 4 row matrix): aa|bb bb|cc|ee|ee cc cc|ee and I want it displayed so that the column names are: aa, bb, cc, dd, and ee. And I want there to be 4 row such that each row counts the number of times each string was present in the matching row above. ie) aa bb cc dd ee 1 1 0 0 0 0 1 1 0 2 0 0 1 0 0 0 0 1 0 1 Does anyone know how to do this in R? I would post my attempt, but it is just getting ugly and complicated. Any help would be much appreciated. Thanks in advance.

  • Incorrect value for UNIQUE_CONSTRAINT_NAME in REFERENTIAL_CONSTRAINTS

    - by van
    I am listing all FK constraints for a given table using INFORMATION_SCHEMA set of views with the following query: SELECT X.UNIQUE_CONSTRAINT_NAME, "C".*, "X".* FROM "INFORMATION_SCHEMA"."KEY_COLUMN_USAGE" AS "C" INNER JOIN "INFORMATION_SCHEMA"."REFERENTIAL_CONSTRAINTS" AS "X" ON "C"."CONSTRAINT_NAME" = "X"."CONSTRAINT_NAME" AND "C"."TABLE_NAME" = 'MY_TABLE' AND "C"."TABLE_SCHEMA" = 'MY_SCHEMA' Everything works perfectly well, but for one particular constraint the value of UNIQUE_CONSTRAINT_NAME column is wrong, and I need it in order to find additional information from the referenced Column. Basically, for most of the rows the UNIQUE_CONSTRAINT_NAME contains the name of the unique constraint (or PK) in the referenced table, but for one particular FK it is the name of some other unique constraint. I dropped and re-created the FK - did not help. My assumption is that the meta-data is somehow screwed. Is there a way to rebuild the meta data so that the INFORMATION_SCHEMA views would actually show the correct data?

  • GWT HTMLTable colaspan feature

    - by Sanjay
    Hello all I am using HTMLTable of import com.google.gwt.user.client.ui.HTMLTable I instantiated it like below: HTMLTable table = new Grid(rows, col); Number of rows and columns are decided by the user input. Now I want to used colspan for the specific rows of the table. One way to this is apply css to the that specific row.But problem with this is that Number of column to span are decided by the user input, i.e It may vary every time. So by using css it is something like making it static. So I want to know the way through which I can do colspan on the rows of the table. and Number of column to span is different every time. Thanks in advance

  • 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?

  • 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 :)

  • 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

  • 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.

  • why this httaccess code results into a redirect loop?

    - by user3606997
    Here I am stuck with my htaccess code. I have been trying to figure it out for the last 11 hours why am I getting a redirect loop for the below code. Options -Indexes +FollowSymLinks RewriteEngine on #Check for no www or www RewriteCond %{HTTP_HOST} ^dummysite.com$ [or] RewriteCond %{HTTP_HOST} ^www.dummysite.com$ [NC] RewriteRule . - [E=FIRSTPART:true] # IE 6 RewriteCond %{HTTP_USER_AGENT} !MSIE\s6 RewriteCond %{ENV:FIRSTPART} true RewriteRule ^(.*)$ https://www.dummysite.com/$1 [R=302,L] Why the above code results into a redirect loop? EDIT: What I actually want is that if the user is from IE6 then he should be redirected to http version with www as prefix no matter if he types www or not in the url. And on the other hand if the user is from any other browsers then he should be redirected to a https version with www as prefix no matter if he types www in the url or not.

  • 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.
