  • ColdFusion Timeout Error

    - by Jason
    I have a scheduled task that runs once a day that builds an XML file that I pass off to another group. Recently the amount of data has greatly increased and is now causing the task to time out (I think). I have tried to optimize my script as much as possible but with no luck. It times out long before an hour and I don't get any kind of ColdFusion error. Instead I get a "This page cannot be found" after it runs. Could this be a timeout someplace other than Coldfusion? Is there a more efficient way to build this XML file? select PersonID, FirstName, LastName from People select d.DepartmentID, DepartmentName, pd.PersonID from Department d inner join PersonDepartment pd on d.DepartmentID = pd.DepartmentID select PaperID, PaperTitle, PaperDescription, pp.PersonID from Paper p inner join PersonPaper pp on p.PaperID = pp.PaperID select DepartmentID, DepartmentName from getDepartments where PersonID = #getPeople.PersonID# select PaperID, PaperDescription from getpapers where PersonID = #getPeople.PersonID# #getPeople.PersonID# #getPeople.Firstname# #getPeople.LastName# #getPersonDepartments.DepartmentID# #getPersonDepartments.DepartmentName# #getPersonPapers.PaperID# #getPersonPapers.PaperDescription# Done!

  • SQL SELECT using in() but excluding others.

    - by Pickledegg
    I have a table called 'countries' linked to another table 'networks' with a many to many relationship: countries countries_networks networks +-------------+----------+ +-------------+----------+ +-------------+---------------+ | Field | Type | | Field | Type | | Field | Type | +-------------+----------+ +-------------+----------+ +-------------+---------------+ | id | int(11) | | id | int(11) | | id | int(11) | | countryName | char(35) | | country_id | int(11) | | name | varchar(100) | +-------------+----------+ | network_id | int(11) | | description | varchar(255) | To retrieve all countries that have a network_id of 6 & 7, I just do the following: ( I could go further to use the networks.name but I know the countries_networks.network_id so i just use those to reduce SQL.) SELECT DISTINCT countryName FROM countries AS Country INNER JOIN countries_networks AS n ON Country.id = n.country_id WHERE n.network_id IN (6,7) This is fine, but I then want to retrieve the countries with a network_id of JUST 8, and no others. I'ver tried the following but its still returning networks with 6 & 7 in. Is it something to do with my JOIN? SELECT DISTINCT countryName FROM countries AS Country INNER JOIN countries_networks AS n ON Country.id = n.country_id WHERE n.network_id IN (8) AND n.network_id not IN(6,7) Thanks.

  • Can jQuery perform a compound select against the top level only?

    - by harpo
    Basically, is there a way to write a.children('.outer').children('.inner') without the intermediate selector? I can't write $('.outer > .inner', a) because I don't want to do full-depth search against a — I know that the .outer elements are immediate children of a. It's partly a matter of "elegance", but partly because I'm trying to avoid "throwaway" element sets. Yes, jQuery may in effect do the same thing, but it has a better chance of optimizing (at least in theory), when it knows the full query's intent.

  • In SQL, a Join is actually an Intersection? And it is also a linkage or a "Sideway Union"?

    - by Jian Lin
    I always thought of a Join in SQL as some kind of linkage between two tables. For example, select e.name, d.name from employees e, departments d where employees.deptID = departments.deptID In this case, it is linking two tables, to show each employee with a department name instead of a department ID. And kind of like a "linkage" or "Union" sideway". But, after learning about inner join vs outer join, it shows that a Join (Inner join) is actually an intersection. For example, when one table has the ID 1, 2, 7, 8, while another table has the ID 7 and 8 only, the way we get the intersection is: select * from t1, t2 where t1.ID = t2.ID to get the two records of "7 and 8". So it is actually an intersection. So we have the "Intersection" of 2 tables. Compare this with the "Union" operation on 2 tables. Can a Join be thought of as an "Intersection"? But what about the "linking" or "sideway union" aspect of it?

  • Getting the most recent entry per group in a select statement

    - by TheObserver
    I have 3 tables to join to get table1.code, table1.series, table2.entry_date, table3.title1 and I'm trying to get the most recent non null table3.title1 grouped by table1.code and table1.series. select table1.code, table1.series, max(table2.entry_date), table3.Title1 from table3 INNER JOIN table2 ON table3.ID = table2.ID INNER JOIN table1 ON table2.source_code = table1.code where table3.Title1 is not NULL group by table1.code, table1.series, table3.Title1 seems to give me all entries with a non null title1 instead of the most recent one. How should I structure the query to just pick the newest version of Title1 per code & series?

  • Wildcard in query for ASP.NET GridView

    - by cinu
    I am using GridView in ASP.NET 2.0. I am want to show the details from 3 tables (SQL2005) in the GridView per my search crieteria (Name of Visitor,Passport Number,Name of Company). It is working, but I want to use a wildcard for searching by first letter of "Name of Visitor". I have my code in the QueryBuilder in GridView (using Configure Datasource). The query is as follows: SELECT FormMaster.NameofCompany, VisitorMaster.NameofVisitor, VisitorMaster.PassportNumber, FormMaster.FormID, VisitorMaster.VisitorID FROM VisitorMaster INNER JOIN VisitorDetails ON VisitorMaster.VisitorID = VisitorDetails.VisitorID INNER JOIN FormMaster ON VisitorDetails.FormID = FormMaster.FormID WHERE (FormMaster.FormStatusID = 1) AND (VisitorMaster.PassportNumber = @PassportNumber ) OR (VisitorMaster.NameofVisitor = @NameofVisitor) OR (FormMaster.NameofCompany = @NameofCompany )

  • SQL Server, fetching data from multiple joined tables. Why is slow?

    - by user562192
    I have problem with performance when retrieving data from SQL Server. My sql query looks something like this: SELECT table_1.id, table_1.value, table_2.id, table_2.value,..., table_20.id, table_20.value From table_1 INNER JOIN table_2 ON table_1.id = table_2.table_1_id INNER JOIN table_3 ON table_2.id = table_3.table_2_id... WHERE table_1.row_number BETWEEN 1 AND 20 So, I am fetching 20 results. This query takes about 5 seconds to execute. When I select only table_1.id, it returns results instantly. Because of that, I guess that problem is not in JOINs, it is in retrieving data from multiple tables. Any suggestions how I would speed up this query?

  • Tag filtering Query using T-SQL and Linq-to-SQL?

    - by EdenMachine
    I'm trying to figure out how to allow a user to enter in a string of tags (keywords separated by spaces) in a textbox to filter a grid of results. Here are the tables: PACKETS *PacketID Name PACKETTAGS *PacketTagID PacketID TagID Tags *TagID Name Here is the basic query without the WHERE parameters: SELECT Packets.Name, Tags.Name AS Tag, PacketTags.PacketTagID FROM Packets INNER JOIN PacketTags ON Packets.PacketID = PacketTags.PacketID INNER JOIN Tags ON PacketTags.TagID = Tags.TagID I need to filter out all the Packets that don't have tags that match any of the words BUT ALSO ONLY include the Packets that have the tags entered in the string of text (spaces separate the tags when entered into the textbox) I'm starting with the basics by figuring this out in t-SQL first but ultimately I need to be able to do this in Linq-to-SQL

  • Sql join, 2 tables, same fields

    - by Lobuno
    I have 2 tables. To simplify: Table 1, users: userId int, userName nvarchar(50) Table 2 , messages: msgId int, msgFrom int, msgTo int... msg1 and msg2, both contain userId. Now I want to get all messages, but instead of the msgFrom I want the user name. I know what to do here: select tabMessages.*, tabUsers.userName as Sender from tabMessages inner join tabUsers on msgFrom=userId where msgId = @someParameter; Everything works fine and dandy. The same to get the user name instead of msgTo. Now the problem is, how do I do to get BOTH fields in the same call? I want to get the table as msgId, msgFrom, msgTo, Sender, Recipient. I have tried as: select tabMessages.*, tabUsers.userName as Sender, tabUsers.userName as Recipient from tabMessages inner join tabUsers on msgFrom=userId and msgTo=userId where msgId = @someParameter; but that doesn't work. I'm using Ms sql2000 by the way.

  • Rails activerecord includes. How to access the included columns?

    - by Lee Quarella
    I my User has_many :event_patrons and EventPatron belongs_to :user. I would like to slap together the user with one specific event patron with something like this sql statement: SELECT * FROM `users` INNER JOIN `event_patrons` ON `event_patrons`.`user_id` = `users`.`id` WHERE `event_patrons`.`event_id` = 1 So in rails I tried this: User.all(:joins => :event_patrons, :condidions => {:event_patrons => {:event_id => 1}}) But that gives me SELECT users.* instead of SELECT *: SELECT `users`* FROM `users` INNER JOIN `event_patrons` ON `event_patrons`.`user_id` = `users`.`id` WHERE `event_patrons`.`event_id` = 1 I then tried to switch the :joins with :include and got a whole jumbled mess that still returned me only the columns in User and none from EventPatron. What am I missing?

  • Matlab - building an array while looping

    - by Mark
    Hello, I have a for loop that loops over one array... for i=1:length(myArray) In this loop, I want to do check on the value of myArray and add it to another array myArray2 if it meets certain conditions. I looked through the Matlab docs, but couldn't find anything on creating arrays without declaring all their values on initialization or reading data into them in one shot. Many thanks!

  • VS 2010 SQL Update for SQL Statement

    - by Mike Tucker
    Please bear with me as I'm just beginning to learn this stuff. I have a VS 2010 Web project up and I'm trying to understand how I can make a custom UpdateCommand (Because I chose to write my own SQL statement, I do not have the option for VS 2010 to auto generate an update command for me.) Problem is: I don't know what the UpdateCommand should look like. Here is my Select: SELECT * FROM Dbo.MainAsset, dbo.Model, dbo.Hardware WHERE MainAsset.device = Hardware.DeviceID AND MainAsset.model = Model.DeviceID Which, VS 2010 turns into: SELECT MainAsset.pk, MainAsset.img, MainAsset.device, MainAsset.model, MainAsset.os, MainAsset.asset, MainAsset.serial, MainAsset.inyear, MainAsset.expyear, MainAsset.site, MainAsset.room, MainAsset.teacher, MainAsset.FirstName, MainAsset.LastName, MainAsset.Notes, MainAsset.Dept, MainAsset.AccountingCode, Model.Model AS Hardware, Model.pk AS Model, Model.DeviceID, Hardware.Computer, Hardware.pk AS Expr3, Hardware.DeviceID AS Expr4 FROM MainAsset INNER JOIN Hardware ON MainAsset.device = Hardware.DeviceID INNER JOIN Model ON MainAsset.model = Model.DeviceID How would I approach updating one column, say "MainAsset.site" if that's changed in the Gridview DDL? Any help constructive help would be appreciated. Thank you.

  • What table is affected by delete when form based on query?

    - by webworm
    In MS Access 2003 I have a form whose record source is equal to a query that involves an INNER JOIN. The join is between a location table and a container table. Containers are objects that are stored in specific locations each location and container are specified by ID values. SELECT DISTINCTROW Container.Container_ID, Location.Location_ID FROM Location INNER JOIN Container ON Location.[Location_ID] = Container.[Location_ID] What I am trying to figure out is this …. When I delete a record (using the form navigation controls) in the form based on the above query which tables are affected? Are records in the Container and Location tables deleted or is it just in the location table? Thanks!

  • PHP while(variable=mysql_fetch_assoc) - explanation

    - by Petr
    Hi, I have been working with C# so this is quite strange for me: while($variable=mysql_fetch_assoc) I have not been able to look up in PHP manual how it works. I guess that in each loop it advances to next element of assoc.array. But what is this generally called in PHP? I am just not used to see '=' in loop condition.

    stack overflow wont let me post images so heres the link: http://4m0.org/images/qt.png This is my application. For this question, ignore the top part with the buttons. I have a QScrollArea Filled with many QGroupBoxes Filled with a horizontal box layout of QLabel (on the left) and QGroupBox (on the right) The right side is a vertical box layout of QPushButtons Every single element, the scrollarea, both boxes, the labels, and the buttons all have their style sheets modified so padding is 0px and margin is 0px. Why do i have all this extra space? The scroll area has space on all sides until its inner elements (the blue boxes) start. Then those boxes have space until its inner elements (the white boxes) start. Can someone tell me what is going on?

  • How do you make long SQL invoked from other code readable?

    - by Artem
    This is a very open question, but I think it can be very beneficial for SQL readability. So you have a Java program, and you are trying to call a monster SQL statement from it, with many subqueries and joins. The starting point for my question is a string constant like this: static string MONSTER_STATEMENT = "SELECT " + " fields" + "WHERE "+ " fieldA = (SELECT a FROM TableC) " + "AND fieldB IN (%s)" + "AND fieldC = %d " + "FROM " " tableA INNER JOIN tableB ON ..."; It later gets filled using String.format and executed. What are you tricks for making this kind of stuff readable? Do you separate your inner joins. Do you indent the SQL itself inside the string? Where do you put the comments? Please share all of the tricks in your arsenal.

  • MySQL: Query to obtain recipes using all given ingredients.

    - by John_A
    hi I have the following simplified tables: CREATE TABLE recipe(id int, name varchar(25)); CREATE TABLE ingredient(name varchar(25)); CREATE TABLE uses_ingredient(recipe_id int, name varchar(25)); I want to make a query that returns all id's of recipes that contain both Chicken and Cream. I have tried SELECT recipe_id FROM uses_ingredient INNER JOIN (SELECT * FROM ingredient WHERE name="Chicken" OR name="Cream") USING (name) GROUP BY recipe_id HAVING COUNT(recipe_id) >= (SELECT COUNT(*) FROM theme); which gives me :"ERROR 1248 (42000): Every derived table must have its own alias" and is probably wrong too. Next I tried SELECT recipe_id FROM (SELECT * FROM ingredient WHERE name="Chicken" OR name="Cream") AS t INNER JOIN uses_ingredient USING (name) GROUP BY recipe_id HAVING COUNT(recipe_id)>= (SELECT COUNT(*) FROM t); which gives "ERROR 1146 (42S02): Table 'recipedb.t' doesn't exist" I want to avoid creating temporary tables including using ENGINE=MEMORY.
