  • SQL: how to get the left 3 numbers from an int

    - by dmr
    I want to retrieve the left 3 numbers from an integer to be stored in a table. For example, if the int is 1234567, I want to retrieve 123. I want the second number (123) to also be an int; I don't want to convert anything to a string. (And yes, really I should be working with strings. But I don't have control over that aspect of the issue.) Thank you!

  • Cannot open a SQL2000 DTS package I imported into SQL2008

    - by RJ
    I am running into a problem trying to open a SQL2000 DTS package I imported into SQL2008. I set up a new server and installed a fresh install of SQL2008. The database I need to run is a SQL2000 database. I moved the database over with no problem but there are a few DTS packages that need to run in legacy on SQL2008. I exported the DTS packages I need out of SQL2000 and imported them successfully into SQL2008. My SQL2008 server is x64. I can see the DTS packages under Data Transformation Service in Legacy but when I try to open the package I get this message. "SQL Server 2000 DTS Designer components are required to edit DTS packages. Install the special web download, "SQL Server 2000 DTS Designer components" to use this feature. (Microsoft.SqlServer.DtsObjectExplorerUI)" I downloaded the components and installed them and still get this error. I researched and found an article about this not working on x64 so I have an x86 machine that I installed the SQL2008 tools and tried to open the package from there and got the same error. I have spent days on this and need help. Has anyone run across this and can tell me what to do. If you have solved this problem, please help me out. Thanks.

  • Improve SQL Server 2005 Query Performance

    - by user366810
    I have a course search engine and when I try to do a search, it takes too long to show search results. You can try to do a search here http://76.12.87.164/cpd/testperformance.cfm At that page you can also see the database tables and indexes, if any. I'm not using Stored Procedures - the queries are inline using Coldfusion. I think I need to create some indexes but I'm not sure what kind (clustered, non-clustered) and on what columns. Thanks

  • Translate SQL to NHibernate Query

    - by Thad
    I have a SQL query that I would like to translate to nhibernate criteria, but I have not found a way to generate the MatchCount field. I tried adding it using a sqlprojection but I could not find a place to set the parameters. SELECT (CASE WHEN LEFT([FirstName], LEN(@Text0)) = @Text0 OR LEFT([FirstName], LEN(@Text1)) = @Text1 OR LEFT([FirstName], LEN(@Text2)) = @Text2 THEN 1 ELSE 0 END + CASE WHEN LEFT([LastName], LEN(@Text0)) = @Text0 OR LEFT([LastName], LEN(@Text1)) = @Text1 OR LEFT([LastName], LEN(@Text2)) = @Text2 THEN 1 ELSE 0 END + CASE WHEN LEFT([PreferredName], LEN(@Text0)) = @Text0 OR LEFT([PreferredName], LEN(@Text1)) = @Text1 OR LEFT([PreferredName], LEN(@Text2)) = @Text2 THEN 1 ELSE 0 END) AS MatchCount , * FROM [client].[Individual] WHERE ( [FirstName] LIKE @Text0 + '%' OR [FirstName] LIKE @Text1 + '%' OR [FirstName] LIKE @Text2 + '%' OR [LastName] LIKE @Text0 + '%' OR [LastName] LIKE @Text1 + '%' OR [LastName] LIKE @Text2 + '%' OR [PreferredName] LIKE @Text0 + '%' OR [PreferredName] LIKE @Text1 + '%' OR [PreferredName] LIKE @Text2 + '%' ) ORDER BY (CASE WHEN LEFT([FirstName], LEN(@Text0)) = @Text0 OR LEFT([FirstName], LEN(@Text1)) = @Text1 OR LEFT([FirstName], LEN(@Text2)) = @Text2 THEN 1 ELSE 0 END + CASE WHEN LEFT([LastName], LEN(@Text0)) = @Text0 OR LEFT([LastName], LEN(@Text1)) = @Text1 OR LEFT([LastName], LEN(@Text2)) = @Text2 THEN 1 ELSE 0 END + CASE WHEN LEFT([PreferredName], LEN(@Text0)) = @Text0 OR LEFT([PreferredName], LEN(@Text1)) = @Text1 OR LEFT([PreferredName], LEN(@Text2)) = @Text2 THEN 1 ELSE 0 END) DESC And yes, this is a ugly statement. Hate having a sql statement in the middle of everthing. Note: There is paging involved and I would prefer not returning all the data to the app server before cutting it down.

  • Linq to SQL duplicating entry when referencing FK

    - by Oscar
    Hi! I am still facing some problems when using LINQ-to-SQL. I am also looking for answers by myself, but this problem is so akward that I am having problems to find the right keywords to look for it. I have this code here: public CustomTask SaveTask(string token, CustomTask task) { TrackingDataContext dataConext = new TrackingDataContext(); //Check the token for security if (SessionTokenBase.Instance.ExistsToken(Convert.ToInt32(token)) == null) return null; //Populates the Task - the "real" Linq to SQL object Task t = new Task(); t.Title = task.Title; t.Description = task.Description; //****The next 4 lines are important**** if (task.Severity != null) t.Severity = task.Severity; else t.SeverityID = task.SeverityID; t.StateID = task.StateID; if (task.TeamMember != null) t.TeamMember = task.TeamMember; else t.ReporterID = task.ReporterID; if (task.ReporterTeam != null) t.Team = task.ReporterTeam; else t.ReporterTeamID = task.ReporterTeamID; //Saves/Updates the task dataConext.Tasks.InsertOnSubmit(t); dataConext.SubmitChanges(); task.ID = t.ID; return task; } The problem is that I am sending the ID of the severity, and then, when I get this situation: DB State before calling the method: ID Name 1 high 2 medium 3 low Call the method selecting "medium" as severity DB State after calling the method: ID Name 1 high 2 medium 3 low 4 medium The point is: -It identified that the ID was related to the Medium entry (and for this reason it could populate the "Name" Column correctly), but if duplicated this entry. The problem is: Why?!! Some explanation about the code: CustomTask is almost the same as Task, but I was having problems regarding serialization as can be seen here I don't want to send the Severity property populated because I want my message to be as small as possible. Could anyone clear to my, why it recognize the entry, but creates a new entry in the DB?

  • C# & SQL Server Authentication

    - by Peter
    Hello, I'm currently developing a C# app with an SQL Server DB back-end. I'm approaching the point of deployment and hitting a problem. The applicaiton will be deployed within an active directory network. As far as SQL authentication goes, I understand that I have 2 options - Windows Authenticaiton or Server Authenticaiton. If I use Server Authentication, I'm concerned that the username and password for the account will be stored in plain text in the app.config file, and therefore leave the database vulnerable. Using Windows Authenticaiton will avoid this issue, however it would mean giving every member of staff within our organisation read/write access to the database in order to run the app correctly. Whilst this is ok, it also means that they can easily connect to the database themselves via other means and directly alter the data outside of the app. I'm guessing there is someting really obvious I'm missing here, but I've been googling all evening to no avail. Any advice/guidance would be much appreciated! Peter Addition - my project is Windows Form based not ASP.NET - is encrypting the app.config file still the right answer? If it is, does anyone have any examples that are not ASP.NET based?

  • compiling a linq to sql query

    - by frenchie
    Hi, I have queries that are built like this: public static List<MyObjectModel> GetData (int MyParam) { using (DataModel MyModelDC = new DataModel()) { var MyQuery = from.... select MyObjectModel { ...} } return new List<MyObjectModel> (MyQuery) } } It seems that using compiled linq-to-sql queries are about as fast as stored procedures and so the goal is to convert these queries into compiled queries. What's the syntax for this? Thanks.

  • How to fix this simple SQL query?

    - by morpheous
    I have a database with three tables: user_table country_table city_table I want to write ANSI SQL which will allow me to fetch all the user data (i.e. user details including the name of the country of the last school and the name of the city they live in now). The problem I am having is that I have to use a self join, and I am getting slightly confused. The schema is shown below: CREATE TABLE user_table (id int, first_name varchar(16), last_school_country_id int, city_id int); CREATE TABLE country_table (id int, name varchar(32)); CREATE TABLE city_table (id int, country_id int, name varchar(32)); This is the query I have come up with so far, but the results are wrong, and sometimes, the db engine (mySQL), asks me if I want to show all [HUGE NUMBER HERE] results - which makes me suspect that I am unintentionally creating a cartesian product somewhere. Can someone explain what is wrong with this SQL statement, and what I need to do to fix it? SELECT usr.id AS id, usr.first_name, ctry1.name as loc_country_name, ctry2.name as school_country_name, city.name as loc_city_name FROM user_table usr, country_table ctry1, country_table ctry2, city_table city WHERE usr.last_school_country_id=ctry2.id AND usr.city_id=city.id AND city.country_id=ctry1.id AND ctry1.id=ctry2.id;

  • Unable to access SQL reporting services on shared site with Themes enabled

    - by Grant
    Hi, i am having some trouble with my IIS web server & SQL reporting services. At the current time my site is playing host to both reporting services (/reports & /reportserver) as well as my personal website (domain.com) Only just recently have i implemented a Theme on my site and as such i have placed a statement in my web.config file directing it to apply a certain theme in the following manner <pages styleSheetTheme="General"> Because of this when i try to access the report pages it failed telling me it couldnt find the Theme so what i did was locate the source files for the /reports & /reportserver directories and place the App_Theme folder in them hoping that would sort everything out. What i am getting now is the following error *Using themed css files requires a header control on the page. e.g. head runat="server" * Does anyone know how i can get around this? Do i have to hack the sql reporting aspx pages? Please note i do NOT want to remove the web.config declaration.

  • Scope of Derived Tables in SQL Server

    - by FailBoy
    I've been looking into SQL recently and exploring a bit. in regards to Temp Tables I have discovered 3 different temp table types: 1) CREATE TABLE #TempTable 2) DECLARE TABLE @TempTable 3) SELECT * FROM (SELECT * FROM Customers) AS TempTable Now I understand the scope behind the #TempTable and the @TempTable types, but what about the derived table as in example 3? Where does this derived table get stored? and if it is declared in 1 transaction, can a 2nd transaction access it, or is the scoping of Derived Tables that same as example 1 and 2?

  • XUL: Printing value from SQL query without using value attribute

    - by Grip
    I want to print the results of an SQL query in XUL with word-wrapping using the description tag. I have the following code: <grid> <columns> <column flex="2" /> <column flex="1" /> </columns> <rows datasources="chrome://glossary/content/db/development.sqlite3" ref="?" querytype="storage" > <template> <query>select distinct * from Terms</query> <action> <row uri="?"> <description value="?name" /> <description value="?desc" /> </row> </action> </template> </rows> This works for printing the data, but since I'm using the value attribute of description, there's no word-wrapping. I don't understand entirely what I'm doing with the value attribute, but I don't seem to be able to get the values of my SQL query in any other way. So, how could I get those values without the value tag? Thanks.

  • WPF & Linq To SQL binding ComboBox to foreign key

    - by ZeroDelta
    I'm having trouble binding a ComboBox to a foreign key in WPF using Linq To SQL. It works fine when displaying records, but if I change the selection on the ComboBox, that change does not seem to affect the property to which it is bound. My SQL Server Compact file has three tables: Players (PK is PlayerID), Events (PK is EventID), and Matches (PK is MatchID). Matches has FKs for the the other two, so that a match is associated with a player and an event. My window for editing a match uses a ComboBox to select the Event, and the ItemsSource is set to the result of a LINQ query to pull all of the Events. And of course the user should be able to select the Event based on EventName, not EventID. Here's the XAML: <ComboBox x:Name="cboEvent" DisplayMemberPath="EventName" SelectedValuePath="EventID" SelectedValue="{Binding Path=EventID, UpdateSourceTrigger=PropertyChanged}" /> And some code-behind from the Loaded event handler: var evt = from ev in db.Events orderby ev.EventName select ev; cboEvent.ItemsSource = evt.ToList(); var mtch = from m in db.Matches where m.PlayerID == ((Player)playerView.CurrentItem).PlayerID select m; matchView = (CollectionView)CollectionViewSource.GetDefaultView(mtch); this.DataContext = matchView; When displaying matches, this works fine--I can navigate from one match to the next and the EventName is shown correctly. However, if I select a new Event via this ComboBox, the CurrentItem of the CollectionView doesn't seem to change. I feel like I'm missing something stupid! Note: the Player is selected via a ListBox, and that selection filters the matches displayed--this seems to be working fine, so I didn't include that code. That is the reason for the "PlayerID" reference in the LINQ query

  • .NET Application with SQL Server CE Database

    - by blu
    I just started using SQL Server CE 3.5 in my WinForms Application (C# in VS 2008 SP1). I've noticed a couple of interesting things I'd like some input on: 1. Copying of sdf file to bin My sdf file is located inside of an Infrastructure project that houses my repository implementations. When the application is first debugged the sdf was copied to debug\bin. This is where all future reads/writes operate. At some point when this is deployed the file will go into a data folder using Click Once, but during development where should I be putting this sdf? Is having it in the bin typical, or are there any other recommendations? 2. Updating sdf It appears that writing to the sdf file does not immediately update the database. I am using Linq-to-SQL and am calling SubmitChanges, but on read the values are not returned. However if I close the application and re-open it the added value is there. Is there an additional flush step I need to take? What is causing this, file locking, buffering, something else? Update 3. Unit Tests I have an MS test project, and the sdf file is not being copied to the correct output directory. I have the settings: Build Action: Content Copy to Output Directory: Copy Always The message is: System.Data.SqlServerCe.SqlCeException: The database file cannot be found. Check the path to the database. I appreciate any guidance on these questions, thanks. If there is a tutorial other than what is on MSDN that you know about that would be great too. Working with CE is proving to be a difficult task and I welcome any help I can find.

  • SQL Query to separate data into two fields

    - by Phillip
    I have data in one column that I want to separate into two columns. The data is separated by a comma if present. This field can have no data, only one set of data or two sets of data saperated by the comma. Currently I pull the data and save as a comma delimited file then use an FoxPro to load the data into a table then process the data as needed then I re-insert the data back into a different SQL table for my use. I would like to drop the FoxPro portion and have the SQL query saperate the data for me. Below is a sample of what the data looks like. Store Amount Discount 1 5.95 1 5.95 PO^-479^2 1 5.95 PO^-479^2 2 5.95 2 5.95 PO^-479^2 2 5.95 +CA8A09^-240^4,CORDRC^-239^7 3 5.95 3 5.95 +CA8A09^-240^4,CORDRC^-239^7 3 5.95 +CA8A09^-240^4,CORDRC^-239^7 In the data above I want to sum the data in the amount field to get a gross amount. Then pull out the specific discount amount which is located between the carat characters and sum it to get the total discount amount. Then add the two together and get the total net amount. The query I want to write will separate the discount field as needed, see store 2 line 3 for two discounts being applied, then pull out the value between carat characters.

  • How can I pivot these key+values rows into a table of complete entries?

    - by CodexArcanum
    Maybe I demand too much from SQL but I feel like this should be possible. I start with a list of key-value pairs, like this: '0:First, 1:Second, 2:Third, 3:Fourth' etc. I can split this up pretty easily with a two-step parse that gets me a table like: EntryNumber PairNumber Item 0 0 0 1 0 First 2 1 1 3 1 Second etc. Now, in the simple case of splitting the pairs into a pair of columns, it's fairly easy. I'm interested in the more advanced case where I might have multiple values per entry, like: '0:First:Fishing, 1:Second:Camping, 2:Third:Hiking' and such. In that generic case, I'd like to find a way to take my 3-column result table and somehow pivot it to have one row per entry and one column per value-part. So I want to turn this: EntryNumber PairNumber Item 0 0 0 1 0 First 2 0 Fishing 3 1 1 4 1 Second 5 1 Camping Into this: Entry [1] [2] [3] 0 0 First Fishing 1 1 Second Camping Is that just too much for SQL to handle, or is there a way? Pivots (even tricky dynamic pivots) seem like an answer, but I can't figure how to get that to work.

  • SQL Binary Microsoft Access - Combining two tables if specific field values are equal

    - by Jordan
    I am new to Microsoft Access and SQL but have a decent programming background and I believe this problem should be relatively simple. I have two tables that I have imported into Access. I will give you a little context. One table is huge and contains generic, global data. The other table is still big but contains specific, regional data. There is only one common field (or column) between the two tables. Let’s call this common field CF. The other fields in both tables are different. I’ll take you through one iteration of what I need to do. I need to take each CF value in the regional, smaller table and find the common CF value in the larger, global table. After finding the match, I need to take the whole “record” or “row” from the global data and copy it over to the corresponding record in the smaller regional table (This should involve creating the new fields). I need to do this for all CF values in the regional, smaller table. I was recommended to use SQL and a binary search, but I am unfamiliar. Let me know if you have any questions. I appreciate the help!

  • Get a unique data in a SQL query

    - by Jensen
    Hi, I've a database who contain some datas in that form: icon(name, size, tag) (myicon.png, 16, 'twitter') (myicon.png, 32, 'twitter') (myicon.png, 128, 'twitter') (myicon.png, 256, 'twitter') (anothericon.png, 32, 'facebook') (anothericon.png, 128, 'facebook') (anothericon.png, 256, 'facebook') So as you see it, the name field is not uniq I can have multiple icons with the same name and they are separated with the size field. Now in PHP I have a query that get ONE icon set, for example : $dbQueryIcons = mysql_query("SELECT * FROM pl_icon WHERE tag LIKE '%".$SEARCH_QUERY."%' GROUP BY name ORDER BY id DESC LIMIT ".$firstEntry.", ".$CONFIG['icon_per_page']."") or die(mysql_error()); With this example if $tag contain 'twitter' it will show ONLY the first SQL data entry with the tag 'twitter', so it will be : (myicon.png, 16, 'twitter') This is what I want, but I would prefer the '128' size by default. Is this possible to tell SQL to send me only the 128 size when existing and if not another size ? In an another question someone give me a solution with the GROUP BY but in this case that don't run because we have a GROUP BY name. And if I delete the GROUP BY, it show me all size of the same icons. Thanks !

  • SQL return ORDER BY result as an array

    - by EarthMind
    Is it possible to return groups as an associative array? I'd like to know if a pure SQL solution is possible. Note that I release that I could be making things more complex unnecessarily but this is mainly to give me an idea of the power of SQL. My problem: I have a list of words in the database that should be sorted alphabetically and grouped into separate groups according to the first letter of the word. For example: ape broom coconut banana apple should be returned as array( 'a' => 'ape', 'apple', 'b' => 'banana', 'broom', 'c' => 'coconut' ) so I can easily created sorted lists by first letter (i.e. clicking "A" only shows words starting with a, "B" with b, etc. This should make it easier for me to load everything in one query and make the sorted list JavaScript based, i.e. without having to reload the page (or use AJAX). Side notes: I'm using PostgreSQL but a solution for MySQL would be fine too so I can try to port it to PostgreSQL. Scripting language is PHP.

  • Optimize SQL connection?

    - by user1484035
    I am building a multi-page web project in HTML and Javascript that is constantly reading from AND writing to an SQL database. I can connect to the database and successfully run my project with this type of connection. var connection = new ActiveXObject("ADODB.Connection") ; var connectionstring="Data Source=<server>;Initial Catalog=<catalog>;User ID=<user>; Password=<password>;Provider=SQLOLEDB"; connection.Open(connectionstring); var rs = new ActiveXObject("ADODB.Recordset"); rs.Open("SELECT * FROM table", connection); rs.MoveFirst while(!rs.eof) { document.write(rs.fields(1)); rs.movenext; } rs.close; connection.close; Works great and runs fine. BUT, the first 5 lines (from var connection = to var rs =) causes the whole browser to freeze for a few seconds while it establishes the connection. I need to speed that up since I am constantly connecting to the database throughout my project. Is there a more effective way of connecting to a SQL database? or is my computer just bad and this should run faster?

  • SQL aggregate query question

    - by Phil
    Hi, Can anyone help me with a SQL query in Apache Derby SQL to get a "simple" count. Given a table ABC that looks like this... id a b c 1 1 1 1 2 1 1 2 3 2 1 3 4 2 1 1 ** 5 2 1 2 ** ** 6 2 2 1 ** 7 3 1 2 8 3 1 3 9 3 1 1 How can I write a query to get a count of how may distinct values of 'a' have both (b=1 and c=2) AND (b=2 and c=1) to get the correct result of 1. (the two rows marked match the criteria and both have a value of a=2, there is only 1 distinct value of a in this table that match the criteria) The tricky bit is that (b=1 and c=2) AND (b=2 and c=1) are obviously mutually exclusive when applied to a single row. .. so how do I apply that expression across multiple rows of distinct values for a? These queries are wrong but to illustrate what I'm trying to do... "SELECT DISTINCT COUNT(a) WHERE b=1 AND c=2 AND b=2 AND c=1 ..." .. (0) no go as mutually exclusive "SELECT DISTINCT COUNT(a) WHERE b=1 AND c=2 OR b=2 AND c=1 ..." .. (3) gets me the wrong result. SELECT COUNT(a) (CASE WHEN b=1 AND c=10 THEN 1 END) FROM ABC WHERE b=2 AND c=1 .. (0) no go as mutually exclusive Cheers, Phil.
