• Using Google Weather API with Lat and Lon - how to format?

  - by Paul

  I am wanting to use the Google Weather API - by passing lat and long values. However it seems Google is needing these formatted differently to the values I have stored. i.e. For the town of McTavish I have values of 45.5 and -73.583 This works here: http://api.wunderground.com/auto/wui/geo/WXCurrentObXML/index.xml?query=45.5,-73.583 But when I use Google it does not: See: www.google.com/ig/api?weather=,,,45.5,-73.583 Any help appreciated. I would prefer to use the Google Data.

• End User Ad-Hoc Reporting Tool: Microsoft SQL Server Management Studio or Microsoft Access?

  - by schultkl

  Our centralized IT department has suggested two primary ad hoc query tools for our general user base of approximately 200 staff members: Microsoft SQL Server Management Studio 2008 (SSMS) Microsoft Access 2003 Environment The backend database is a read-only Microsoft SQL Server 2005 database. The schema is 400+ tables; allowing access to the raw data for our general staff would be a disaster. We will be building an "abstraction layer" over the raw data for our general staff to run ad hoc queries against. The abstraction layer will most likely contain a number of views. A number of users have basic knowledge in Microsoft Access; none have used SSMS. Which of the above tools (or alternative) would be best for a decidedly non-techie user base of approximately 200 people? What are the pros and cons of each? Also, the IT department has suggested teaching people T-SQL so they may use SSMS. Is this reasonable?

• jQuery get Function Not Returning Data

  - by senfo

  I'm trying to use the jQuery get function to render the results of an HTML page in a div on my page. The result of the get function appears to be successful because the value of textStatus (in the following code block) is "success". The value of data, however, is always empty. $(document).ready(function() { $.get('http://www.google.com', function(data, textStatus){ $('#RSSContent').html(textStatus + ' ' + data); }); }); Any idea what I might be doing wrong? Note: The final code will query an RSS feed, which I plan on transforming and rendering as HTML in the RSSContent div. I simply used http://www.google.com for testing purposes.

• Using RDL files in Web ReportViewer

  - by user54064

  I want to use a rdl file with the query information stored in it. I don't want to have to convert it to a rdlc file. I have an ASP.NET app that I want to show the report. I thought I would use a ReportViewer on my page and then have it use the rdl file. However, I get an error and in researching it appears that I have to convert the file to an rdlc file. I don't want to strip out the data contained in the report. How can I show the report to the user by running the rdl report?

• Retrieve names by ratio of their occurance

  - by jjiffer

  Hello, I'm somewhat new to SQL queries, and I'm struggling with this particular problem. Let's say I have query that returns the following 3 records (kept to one column for simplicity): Tom Jack Tom And I want to have those results grouped by the name and also include the fraction (ratio) of the occurrence of that name out of the total records returned. So, the desired result would be (as two columns): Tom | 2/3 Jack | 1/3 How would I go about it? Determining the numerator is pretty easy (I can just use COUNT() and GROUP BY name), but I'm having trouble translating that into a ratio out of the total rows returned. Any help is much appreciated!

• MySQL/SQL: Update with correlated subquery from the updated table itself

  - by Roee Adler

  I have a generic question that I will try to explain using an example. Say I have a table with the fields: "id", "name", "category", "appearances" and "ratio" The idea is that I have several items, each related to a single category and "appears" several times. The ratio field should include the percentage of each item's appearances out of the total number of appearances of items in the category. In pseudo-code what I need is the following: For each category find the total sum of appearances for items related to it. For example it can be done with (select sum("appearances") from table group by category) For each item set the ratio value as the item's appearances divided by the sum found for the category above Now I'm trying to achieve this with a single update query, but can't seem to do it. What I thought I should do is: update Table T set T.ratio = T.appearances / ( select sum(S.appearances) from Table S where S.id = T.id ) But MySQL does not accept the alias T in the update column, and I did not find other ways of achieving this. Any ideas?

• Keeping a large volume of data in Session - Suggestions / alternatives?

  - by Fishcake

  I'm developing a web app for which the client wants us to query their data as little as possible. The data will be coming from a Microsoft CRM instance. So we've agreed that data will only be queried as and when it is needed, therefore if a web user wants to see a list of contacts (for example) that list is fetched into a local DataTable. Then if a new contact is created on the website the new contact is sent to CRM and added to the local DataTable at the same time. Likewise for edits. If the user then looks at their contacts again the data will just come from the local DataTable. At the moment local data is being kept in Session but my concern is that too much memory will start being used up. However traffic is expected to be pretty small, perhaps no more than 20 concurrent users so am I worrying about nothing or is there a better way you can suggest to handle this?

• SQLserver multithreaded locking with TABLOCKX

  - by WilfriedVS

  I have a table "tbluser" with 2 fields: userid = integer (autoincrement) user = nvarchar(100) I have a multithreaded/multi server application that uses this table. I want to accomplish the following: Guarantee that field user is unique in my table Guarantee that combination userid/user is unique in each server's memory I have the following stored procedure: CREATE PROCEDURE uniqueuser @user nvarchar(100) AS BEGIN BEGIN TRAN DECLARE @userID int SET nocount ON SET @userID = (SELECT @userID FROM tbluser WITH (TABLOCKX) WHERE [user] = @user) IF @userID <> '' BEGIN SELECT userID = @userID END ELSE BEGIN INSERT INTO tbluser([user]) VALUES (@user) SELECT userID = SCOPE_IDENTITY() END COMMIT TRAN END Basically the application calls the stored procedure and provides a username as parameter. The stored procedure either gets the userid or insert the user if it is a new user. Am I correct to assume that the table is locked (only one server can insert/query)?

• Select the first row in a join of two tables in one statement

  - by Oscar Cabrero

  hi i need to select only the first row from a query that joins tables A and B, on table B exist multiple records with same name. there are not identifiers in any of the two tables. i cannt change the scheme either because i do not own the DB TABLE A NAME TABLE B NAME DATA1 DATA2 Select Distinct A.NAME,B.DATA1,B.DATA2 From A Inner Join B on A.NAME = B.NAME this gives me NAME DATA1 DATA2 sameName 1 2 sameName 1 3 otherName 5 7 otherName 8 9 but i need to retrieve only one row per name NAME DATA1 DATA2 sameName 1 2 otherName 5 7 i was able to do this by adding the result into a temp table with a identity column and the select the Min Id per name. the problem here is that i require to do this in one single statement. this is a DB2 database thanks

• Problem with SQL syntax (probably simple)

  - by Bryan Folds

  I'm doing some custom database work for a module for Drupal and I get the following SQL error when trying to create my table: user warning: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'DEFAULT NULL, rooms INT DEFAULT NULL, adults INT DEFAULT NULL, children' at line 14 query: CREATE TABLE dr_enquiry ( eId INT unsigned NOT NULL auto_increment, eKey VARCHAR(16) NOT NULL, dateSent INT NOT NULL DEFAULT 0, status VARCHAR(30) NOT NULL DEFAULT 'Unanswered', custName VARCHAR(50) NOT NULL, custEmail VARCHAR(200) NOT NULL, custPhone VARCHAR(25) NOT NULL, custCountry VARCHAR(40) NOT NULL, custIP VARCHAR(11) DEFAULT NULL, offerName VARCHAR(100) NOT NULL, offerURL VARCHAR(200) NOT NULL, arrival DATETIME DEFAULT NULL, departure DEFAULT NULL, rooms INT DEFAULT NULL, adults INT DEFAULT NULL, children INT DEFAULT NULL, childAges VARCHAR(32) DEFAULT NULL, toddlers INT DEFAULT NULL, toddlerAges VARCHAR(32) DEFAULT NULL, catering VARCHAR(255) DEFAULT NULL, comments VARCHAR(255) DEFAULT NULL, agent VARCHAR(100) DEFAULT NULL, voucher VARCHAR(100) DEFAULT NULL, PRIMARY KEY (eId) ) /*!40100 DEFAULT CHARACTER SET UTF8 */ in /home/travelco/public_html/includes/database.inc on line 550.

• browser back acts on nested iframe before the page itself - is there a way to avoid it??

  - by kfiroo

  hi, i have a page with dynamic data loaded by some ajax and lots of javascript. the page contains a list from which the user can choose and each selected value loads new data to the page. one of these data items is a url provided to an iframe. i use jQuery BBQ: Back Button & Query Library to simulate the browser-back behavior. all works well besides the fact that when i click the back button for the first time the iframe goes back to its previous location and then i need to click back again to make the page go back. is there a way to disable the iframe's back behavior?

• overlay text on some else's window - HUD

  - by taglius

  I am interested in writing an app that overlays a small heads up display (HUD) over another application, in VB.NET. Does anyone have an example of this? I will need to enumerate all open windows to find the window that I want, and then overlay some text in a specific position on the window. If the user moves that window, my text will need to follow. (I will probably be painting the text in a loop over and over). Edit: nobody answered my original query - I added C# to the keywords to see if any of gurus in that language might have an answer. thanks.

• Easy way to parse a url in C++ cross platform?

  - by Andrew Bucknell

  I need to parse a url to get the protocol host path and query in an application I am writing in c++. The application is intended to be cross platform. Im surprised I cant find anything that does this in boost or poco libraries. Is it somewhere obvious Im not looking? Any suggestions on appropriate open source libs? Or is this something I just have to do my self? Its not super complicated but it seems such a common task I am surprised there isnt a common solution.

• Single Large v/s Multiple Small MySQL tables for storing Options

  - by Prasad

  Hi there, I'm aware of several question on this forum relating to this. But I'm not talking about splitting tables for the same entity (like user for example) Suppose I have a huge options table that stores list options like Gender, Marital Status, and many more domain specific groups with same structure. I plan to capture in a OPTIONS table. Another simple option is to have the field set as ENUM, but there are disadvantages of that as well. http://www.brandonsavage.net/why-you-should-replace-enum-with-something-else/ OPTIONS Table: option_id <will be referred instead of the name> name value group Query: select .. from options where group = '15' - Since this table is expected to be multi-tenant, the no of rows could grow drastically. - I believe splitting the tables instead of finding by the group would be easier to write & faster to execute. - or perhaps partitioning by the group or tenant? Pl suggest. Thanks

• SQL syntax problem (multiple selects)

  - by user279521

  I am having problems retrieving accurate data values with my stored proc query below: CREATE PROCEDURE usp_InvoiceErrorLog @RecID int AS DECLARE @ErrorString as varchar(1000), @ErrorCode as int; Select @ErrorCode = ErrorCode from tbl_AcctRecv_WebRpt Where RecID = @RecID; IF NOT(@ErrorCode = NULL) Begin Select @ErrorString = ErrorDesc from tbl_ErrDesc Where ErrorCode = @ErrorCode End Select RecID, VendorNum, VendorName, InvNum, InvTotal, (SELECT CONVERT(VARCHAR(11), InvDate, 106) AS [DD MON YYYY]) As InvDate, TicketRequestor, ErrorCode, @ErrorString as ErrorDesc from tbl_AcctRecv_WebRpt Where RecID = @RecID The ErrorDesc column (in the final select statement at the bottom) returns a NULL value, when it should return a valid string data. Any ideas?

• jQuery: Preventing list scroll?

  - by Legend

  I have this scenario: Using an ajax query I fetch some data items and push them into a ul element as an li element. I use $("ulele").append(new_li_item). I wrote my own custom scroll for this ul element using the following whenever an event is detected: $("ulele").animate({scrollTop: '+=' + 200}, 'slow'); The problem is when I fire that event and the list scrolls due to the animate function above, I want to keep it stable for at least a few seconds. When it scrolls down, elements are still being pushed so the list keeps scrolling no matter what. Is there a way I can pause this from happening without really stopping the activity of pushing elements into the ul list?

• For SQL select returning more than 1 value, how are they sorted when Id is GUID?

  - by Chris F

  I'm wondering how MSSQL orders data that is returned from a query and the Id columns of the respective tables are all of type uniqueidentifier. I'm using NHibernate GuidComb when creating all of the GUIDs and do things like: Sheet sheet = sheetRepository.Get(_SheetGuid_); // has many lines items IList<SheetLineItem> lineItems = sheet.LineItems; I'm just trying to figure out how they'll be ordered when I do something like: foreach (SheetLineItem lineItem in lineItems) I can't see to find a good article on the way GUIDs are compared by SQL when being ordered, if that's what's happening.

• Core Data: Multiple conditions inside relational aggregate operations

  - by Uzaak

  I have an SQLite table used by Core Data with the following elements: Name: John LastName: Foobar Age: 23 Name: Bob LastName: Baz Age: 37 Name: Peter LastName: Fooqux Age: 32 Name: John LastName: Bar Age: 29 Those are all in a to-many relationship from another object "Company". I need to query the database and retrieve all Company objects with employees called "John" but whose last name does NOT contain "Foo". I did go as far as to make the following predicate: [NSPredicate predicateWithFormat:@"ANY employee.name = 'John'"]; How do I get to filter only by companies whose Johns don't have "Foo" in their last names?

• Querying Two Tables At Once

  - by John

  Hello, I am trying to do what I believe is called a join query. First, in a MySQL table called "login," I want to look up what "loginid" is in the record where "username" equals $profile. (This will be just one record / row in the MySQL table). Then, I want to take that "loginid" and look up all rows / records in a different MySQL table called "submission," and pull data that have that "loginid." This could possibly be more than one record / row. How do I do this? The code below doesn't seem to work. Thanks in advance, John $profile = mysql_real_escape_string($_GET['profile']); $sqlStr = "SELECT l.username, l.loginid, s.loginid, s.submissionid, s.title, s.url, s.datesubmitted, s.displayurl FROM submission AS s, login AS l WHERE l.username = '$profile', s.loginid = l.loginid ORDER BY s.datesubmitted DESC";

• INSERT INTO ... SELECT FROM ... ON DUPLICATE KEY UPDATE

  - by dnagirl

  I'm doing an insert query where most of many columns would need to be updated to the new values if a unique key already existed. It goes something like this: INSERT INTO lee(exp_id, created_by, location, animal, starttime, endtime, entct, inact, inadur, inadist, smlct, smldur, smldist, larct, lardur, lardist, emptyct, emptydur) SELECT id, uid, t.location, t.animal, t.starttime, t.endtime, t.entct, t.inact, t.inadur, t.inadist, t.smlct, t.smldur, t.smldist, t.larct, t.lardur, t.lardist, t.emptyct, t.emptydur FROM tmp t WHERE uid=x ON DUPLICATE KEY UPDATE ...; //update all fields to values from SELECT, except for exp_id, created_by, location, animal, starttime, endtime I'm not sure what the syntax for the UPDATE clause should be. How do I refer to the current row from the SELECT clause?

• search for a winner, returning their rank

  - by incrediman

  Earlier I asked this question, which basically asked how to list 10 winners in a table with many winners, according to their points. This was answered. Now I'm looking to search for a given winner X in the table, and find out what position he is in, when the table is ordered by points. For example, if this is the table: Winners: NAME:____|__POINTS: Winner1 | 1241 Winner2 | 1199 Sally | 1000 Winner4 | 900 Winner5 | 889 Winner6 | 700 Winner7 | 667 Jacob | 623 Winner9 | 622 Winner10 | 605 Winner11 | 600 Winner12 | 586 Thomas | 455 Pamela | 434 Winner15 | 411 Winner16 | 410 These are possible inputs and outputs for what I want to do: Query: "Sally", "Winner12", "Pamela", "Jacob" Output: 3 12 14 623 How can I do this? Is it possible, using only a MySQL statement? Or do I need PHP as well? This is the kind of thing I want: WHEREIS FROM Winners WHERE Name='Sally' LIMIT 1 Ideas?

• PL/SQL bulk collect into associative array with sparse key

  - by Dan

  I want to execute a SQL query inside PL/SQL and populate the results into an associative array, where one of the columns in the SQL becomes the key in the associative array. For example, say I have a table Person with columns PERSON_ID INTEGER PRIMARY KEY PERSON_NAME VARCHAR2(50) ...and values like: PERSON_ID | PERSON_NAME ------------------------ 6 | Alice 15 | Bob 1234 | Carol I want to bulk collect this table into a TABLE OF VARCHAR2(50) INDEX BY INTEGER such that the key 6 in this associative array has the value Alice and so on. Can this be done in PL/SQL? If so, how?

• SQL Server union selects built dynamically from list of words

  - by Adam Tuttle

  I need to count occurrence of a list of words across all records in a given table. If I only had 1 word, I could do this: select count(id) as NumRecs where essay like '%word%' But my list could be hundreds or thousands of words, and I don't want to create hundreds or thousands of sql requests serially; that seems silly. I had a thought that I might be able to create a stored procedure that would accept a comma-delimited list of words, and for each word, it would run the above query, and then union them all together, and return one huge dataset. (Sounds reasonable, right? But I'm not sure where to start with that approach...) Short of some weird thing with union, I might try to do something with a temp table -- inserting a row for each word and record count, and then returning select * from that temp table. If it's possible with a union, how? And does one approach have advantages (performance or otherwise) over the other?
