  • Get recursive data with sql server

    - by user228777
    I am trying to get recursive data. Following code returns all parents on the top and then the children. I would like to get data Parent 1 – his children then parent 2 - his children then parent3 – his children. How do I do this? USE Subscriber GO WITH Parent (ParentId, Id, Name,subscriberID) AS ( -- Anchor member definition SELECT A.ParentId,A.id, A.name,A.SubscriberId FROM Subscriber.Budget.SubscriberCategory AS A WHERE ParentId IS NULL UNION ALL -- Recursive member definition SELECT B.ParentId, B.id, B.name,B.SubscriberId FROM Subscriber.Budget.SubscriberCategory AS B INNER JOIN Parent AS P ON B.ParentId = P.Id ) -- Statement that executes the CTE SELECT parentId, id, name FROM Parent where subscriberID = '1C18093B-5031-42E4-9251-CEF69114365F' GO

  • Prevent Excel from evaluating unneeded expressions in OR()

    - by Wesley
    IF(OR(ISNA(MATCH(8,B10:B17,0)),MATCH(8,B10:B17,0)>8),"",...BLAH...) I understand how to fix this problem by rearranging my formula. I have it the way it is to show this point. You can see the OR() statement checks to see if the first MATCH() returns NA. When it does, OR() should automatically return TRUE and not evaluate the second MATCH() because conditions have been met for the OR() to return true no matter what other arguments there are. You'll notice that the first and second MATCH() functions do the same thing. What's happening is the entire function is returning NA because the second MATCH() is executing even though it doesn't have to, the OR() has been satisfied with one TRUE, therefore the function should return "". Is this a bug or is this intentional?

  • Can I get.seed() somehow?

    - by a different ben
    In reference to the statement set.seed(), can I get the seed instead after running some code if I didn't set it explicitly? I've been re-running some code containing a function that randomises some sample of the input data (the function is part of the kohonen package). After playing with it for some time to see the variety of output (it was an 'unstable' problem), I noticed one result that was pretty interesting. I of course had not used set.seed(), but wondered if I could get the seed after running the code to reproduce the result? In ?set.seed I see .Random.seed saves the seed set for the uniform random-number generator But I don't know how that helps.

  • Seeking assistance with Escaping Data for MySQL queries

    - by JM4
    Please don't send me a link to php.net referencing mysql_real_escape_string as the only response. I have read through the page and while I understand the general concepts, I am having some trouble based on how my INSERT statement is currently built. Today, I am using the following: $sql = "INSERT INTO tablename VALUES ('', '$_SESSION['Member1FirstName'], '$_SESSION['Member1LastName'], '$_SESSION['Member1ID'], '$_SESSION['Member2FirstName'], '$_SESSION['Member2LastName'], '$_SESSION['Member2ID'] .... and the list goes on for 20+ members with some other values entered. It seems most people in the examples already have all their data stored in an array. On my site, I accept form inputs, action="" is set to self, php validation takes place and if validation passes, data is stored into SESSION variables on page 2 then redirected to the next page in the process (page 3) (approximately 8-10 pages in the whole process). thanks!

  • Defining action on window load

    - by zac
    I am trying to get a page to display specific properties depending on whether or not a specific cookie is set... I am trying this var x = readCookie('age'); window.onload=function(){ if (x='null') { document.getElementById('wtf').innerHTML = ""; }; if (x='over13') { document.getElementById('wtf').innerHTML = ""; }; if (x='not13') { document.getElementById('emailBox').innerHTML = "<style type=\"text/css\">.formError {display:none}</style><p>Good Bye</p><p>You must be 13 years of age to sign up.</p>"; }; } It always just defaults to whatever is in the first if statement... I am still learning my javaScript so I am sure this is sloppy.. can someone please help me get this working?

  • Easy way to compute how close an auto_increment is to its maximum value?

    - by David M
    So yesterday we had a table that has an auto_increment PK for a smallint that reached its maximum. We had to alter the table on an emergency basis, which is definitely not how we like to roll. Is there an easy way to report on how close each auto_increment field that we use is to its maximum? The best way I can think of is to do a SHOW CREATE TABLE statement, parse out the size of the auto-incremented column, then compare that to the AUTO_INCREMENT value for the table. On the other hand, given that the schema doesn't change very often, should I store information about the columns' maximum values and get the current AUTO_INCREMENT with SHOW TABLE STATUS?

  • PHP preg_match Math Function

    - by Matt
    I'm writing a script that will allow a user to input a string that is a math statement, to then be evaluated. I however have hit a roadblock. I cannot figure out how, using preg_match, to dissallow statements that have variables in them. Using this, $calc = create_function("", "return (" . $string . ");" ); $calc();, allows users to input a string that will be evaluated, but it crashes whenever something like echo 'foo'; is put in place of the variable $string.

  • MS SQL Specific Tables Hanging at Queries

    - by Jonn
    I have SQL Server 2008. I run a query in a table on a database. The weirdest thing keeps happening. I run a simple select statement on the table. I know there are 62 rows in the table but it gets stuck at row 48 and goes on "querying...". Waited already for hours and it didn't move on from there. I only know of two programs, and one reporting service connecting to that particular table and one other user. Does anyone have any idea on what could be causing this and how I could trace the source of the lock on that table? As a side note, I noted that the logs only had a notice that Autogrow failed the day before I checked. Could this have something to do with it?

  • Making linq avoid using in memory filtering where possible

    - by linqmonkey
    Consider the these two LINQ2SQL data retrieval methods. The first creates a 'proper' SQL statement that filters the data, but requires passing the data context into the method. The second has a nicer syntax but loads the entire list of that accounts projects, then does in memory filtering. Is there any way to preserve the syntax of the second method but with the performance advantage of the first? public partial class Account { public IQueryable<Project> GetProjectsByYear(LinqDataContext context, int year) { return context.Projects.Where(p => p.AccountID==this.AccountID && p.Year==year).OrderBy(p => p.ProjectNo) } public IQueryable<Project> GetProjectsByYear(int year) { return this.Projects.Where(p => p.Year==year).OrderBy(p => p.ProjectNo).AsQueryable() } }

  • Error messages in ASP.NET with jQuery UI

    - by eugeneK
    I've been using my own Error reporting module which was combination of simple c# and jQueryUI Dialog. Problem is that once error or success occurs i do write it's value to session. It does work pretty good on pages with Responce.Redirect on error but not on pages where i catch an error and then return to same form. My question is why does session which added pre-postback fails to load in pages where i have return statement on some condition. And if there another way to save errors and success message except in session ? Maybe global variables or something like that ...

  • Preserving NULL values in a Double Variable

    - by Sam
    Hi, I'm working on a vb.net application which imports from an Excel spreadsheet. If rdr.HasRows Then Do While rdr.Read() If rdr.GetValue(0).Equals(System.DBNull.Value) Then Return Nothing Else Return rdr.GetValue(0) End If Loop Else I was using string value to store the double values and when preparing the database statement I'd use this code: If (LastDayAverage = Nothing) Then command.Parameters.AddWithValue("@WF_LAST_DAY_TAG", System.DBNull.Value) Else command.Parameters.AddWithValue("@WF_LAST_DAY_TAG", Convert.ToDecimal(LastDayAverage)) End If I now have some data with quite a few decimal places and the data was put into the string variable in scientific notation, so this seems to be the wrong approach. It didn't seem right using the string variable to begin with. If I use a double or decimal type variable, the blank excel values come across as 0.0. How can I preserve the blank values? Thanks

  • Drupal - db_fetch_array returns NULL for every row

    - by darudude
    I'm using Drupal's db_fetch_array to fetch rows from my db_query. However, every row returned is equal to NULL. Typing the query into PHP myadmin works, so I have no idea whats going on. db_num_rows returns the number of rows as well. Here is the code: if(count($rebuild_ids)) { $ids=implode(",",$rebuild_ids); $type_stmt = "SELECT * from {" . ItemType::$type_table_name . "} where id IN ($ids)"; $new_items=db_query($type_stmt); if(!$new_items || db_num_rows($new_items) == 0) { return; } while($row = db_fetch_array($new_items)); { if ($row!=NULL) { echo "I work!" $game_items[] = $row['id']; ItemInstance::$nid_to_item_type_code[$row['nid']] = $row['id']; } } } However, it never gets into the third if statement (i.e. never echos "I work!") Any ideas?

  • Variable within variable possible?

    - by JM4
    I am trying to create a loop statement for some of my code and am wondering how I can put a variable within another variable. For example: <?php $j=1; while ($j <= 9): { $f$jfname = $_SESSION['F$jFirstName']; $f$jmi = $_SESSION['F$jMI']; $f$jlname = $_SESSION['F$jLastName']; } $j++; endwhile; ?> Where the goal is to have the j variable increase during the loop and change the values as: $f1fname $f2fname $f3fname and so on. Any ideas?

  • Multiple column Union Query without duplicates

    - by Adam Halegua
    I'm trying to write a Union Query with multiple columns from two different talbes (duh), but for some reason the second column of the second Select statement isn't showing up in the output. I don't know if that painted the picture properly but here is my code: Select empno, job From EMP Where job = 'MANAGER' Union Select empno, empstate From EMPADDRESS Where empstate = 'NY' Order By empno The output looks like: EMPNO JOB 4600 NY 5300 MANAGER 5300 NY 7566 MANAGER 7698 MANAGER 7782 MANAGER 7782 NY 7934 NY 9873 NY Instead of 5300 and 7782 appearing twice, I thought empstate would appear next to job in the output. For all other empno's I thought the values in the fields would be (null). Am I not understanding Unions correctly, or is this how they are supposed to work? Thanks for any help in advance.

  • Debugging (displaying) SQL command sent to the db by SQLAlchemy

    - by morpheous
    I have an ORM class called Person, which wraps around a person table: After setting up the connection to the db etc, I run the ff statement. people = session.query(Person).all() The person table does not contain any data (as yet), so when I print the variable people, I get an empty list. I renamed the table referred to in my ORM class People, to people_foo (which does not exist). I then run the script again. I was surprised that no exception was thrown when attempting to access a table that does not exist. I therefore have the following 2 questions: How may I setup SQLAlchemy so that it propagates db errors back to the script? How may I view (i.e. print) the SQL that is being sent to the db engine If it helps, I am using PostgreSQL as the db

  • Attention all SQL gods! Query help needed.

    - by gurun8
    I need a little help putting together a SQL query that will give me the following resultsets: and The data model looks like this: The tricky part for me is that the columns to the right of the "Product" in the resultset are really columns in the database but rather key/value pairs spanned across the data model. Table data is as follows: My apologies in advance for the image heavy question and the image quality. This just seemed like the easiest way to convey the information. It'll probably take someone less time to write the query statement to achieve the results. By the way, the "product_option" table image is truncated but it illustrated the general idea of the data structure. The MySQL server version is 5.1.45.

  • Recursion: using values passed in parameters

    - by Tom Lilletveit
    I got this line of code that pops a int of the array saves it to int element then removes it from array. then in the return statement return CountCriticalVotes(rest, blockIndex + element); it ads it to the blockIndex variable and if it reaches 10 before the array is empty it returns 1. But my problem is this, I do not want it to add up all the values in the array in the parameter, but only add one then revert the parameter value back to it´s original state, then add a new, revert etc... How would i do this? int NumCriticalVotes :: CountCriticalVotes(Vector<int> & blocks, int blockIndex) { if (blockIndex >= 10) { return 1; } if (blocks.isEmpty()) { return 0; } else { int element = blocks.get(0); Vector<int> rest = blocks; rest.remove(0); return CountCriticalVotes(rest, blockIndex + element);

  • Dataset Binding stored procedures update/insert/delete

    - by Jin
    Hi all, I am currently having a problem since the DB has been changed. I am using Datasets for a c# application, and there is a user management system. For the security issues, our current DB design is like user log into app. DB returns a session ID On use of any other stored procedures, a session ID must be specified. BUT, the DB didn't request session ID before. since I am using the datasets, I used update/insert/delete stored procedures with "TableAdaptor Configuration Wizard". Bind Commands to Existing Stored Procedures (choose stored procedures to call and specify any reuiqred parameters) Now, it seems like I have to specify session ID for Insert/Update/Delete stored procedures. How do I specify session ID parameter here? It seems like I have to pick one return parameter variable from a select statement. Thanks,

  • How to access Oracle system tables from inside of a PL/SQL function or procedure?

    - by mjumbewu
    I am trying to access information from an Oracle meta-data table from within a function. For example (purposefully simplified): CREATE OR REPLACE PROCEDURE MyProcedure IS users_datafile_path VARCHAR2(100); BEGIN SELECT file_name INTO users_datafile_path FROM dba_data_files WHERE tablespace_name='USERS' AND rownum=1; END MyProcedure; / When I try to execute this command in an sqlplus process, I get the following errors: LINE/COL ERROR -------- ----------------------------------------------------------------- 5/5 PL/SQL: SQL Statement ignored 6/12 PL/SQL: ORA-00942: table or view does not exist I know the user has access to the table, because when I execute the following command from the same sqlplus process, it displays the expected information: SELECT file_name FROM dba_data_files WHERE tablespace_name='USERS' AND rownum=1; Which results in: FILE_NAME -------------------------------------------------------------------------------- /usr/lib/oracle/xe/oradata/XE/users.dbf Is there something I need to do differently?

  • MULTIPLE CRITERIA TABLE JOIN

    - by user1447203
    I have a table listing clothing items (shirt, trousers, etc) named . Each item is identified with a unique CLOTHING.CLOTHING_ID. So a blue shirt is 01, a flowery shirt is 12 and jeans are 07 say. I have a second table identifying outfits with a column for shirts, for trousers, shoes etc. For example Outfit 1: shirt 01, trousers 07 (i.e. blue shirt with jeans) Outfit 2: shirt 12, trousers 07 (so flowery shirt with jeans). This table is named and each outfit is unique with OUTFIT_LIST.OUTFIT_ID. I want to produce a select statement that will list each outfit's contents, i.e. find the clothing specified in Outfit 1. Any help would be very much appreciated, and apologies in advance if I am missing a very simple solution. I have been playing with JOINS of all descriptions and CONCATS and so on with now luck - I am very new to this. Thanks.

  • jQuery selector to target any CSS name (of multiple present) starting with a prefix?

    - by John K
    I'm considering one selection statement that would target one of many css class names in a single class attribute value based on a string prefix. For example, I want any detail- prefixed class names to get targeted from the following sample links. <a href="eg.html" class="detail-1 pinkify another"> <a href="eg.html" class="something detail-55 minded"> <a href="eg.html" class="swing narrow detail-Z"> <a href="eg.html" class="swing narrow detail-Z detail-88 detail-A"> It's reminiscent of how [class|="detail"] prefix selector works on a scalar attribute value, and also of .hasClass(className), but my question needs both concepts applied simultaneously. Note: The detail- prefix won't necessarily be the first class name of the bunch.

  • How to use php variables (arrays) in mysql select statements?

    - by davidconn
    Hi everybody, How do you use a php variable (array) inside a mysql select statement? I am designing an auction site and currently working on a page that lets people view a list of all the current bids for an item. I want to display 3 columns: amountbid - the amount each bidder has bid for the item (held in tblbid) bidderid - the id of each bidder who has bid (found in tbluser) total_positivity_feedback - how many users have left positive feedback for the bidder (calculated from tblfeedback) To find the 'amount' and the 'bidderid' columns i pass the essayid URL parameter from the previous page. This works fine. Despite this, i can't display the total_positivity_feedback column for the various users who have made each bid. My mysql query looks like this: select tblbid.bidderid, tblbid.amount, (select count(tblfeedback.feedbackid) from tblfeedback WHERE tblfeedback.writerid = "ARRAY VARIABLE GOES HERE") AS total_positivity_feedback FROM tblbid WHERE tblbid.essayid = $essayid_bids I assume that the only way to accomplish this is to make the variable contain the bidderid's of those people who bid for that particular essay? I can't seem to work out how to do this tho?!? Many thanks for your help

  • Possible to exclude or reorder a column from `*` ?

    - by Earlz
    Is it possible to exclude a column from a select * from table statement with SQL Server? I have a need for this and this is my only option other than parsing a raw SQL string to get out the required field names (I really don't want to do that). Just to be bold. When the query is made I do not have access to the list of fields needed from the table but I do know which field I do not need. This is part of a complex multi-part query. Surely there must be some way even if it's "hackish" such as using table variables or views My other option is to reorder the columns. My problem is with ExecuteScalar SQL functions which get the first row and first column.
