  • SQL Join a View with a Table

    - by gamerzfuse
    CREATE VIEW qtyorderedview AS SELECT titleditors.title_id, titleditors.ed_id, salesdetails.title_id, salesdetails.qty_shipped FROM titleditors, salesdetails WHERE titleditors.title_id = salesdetails.title_id I am using the above SQL statement to create a view. I need to show Editors First Name, Last Name, City where they shipped more than 50 books. The three tables I have are: create table editors ( ed_id char(11), ed_lname varchar(20), ed_fname varchar(20), ed_pos varchar(12), phone varchar(10), address varchar(30), city varchar(20), state char(2), zip char(5), ed_boss char(11)); create table titleditors ( ed_id char(11), title_id char(6), ed_ord integer); create table salesdetails ( sonum integer, qty_ordered integer, qty_shipped integer, title_id char(6), date_shipped date); Can anyone tell me what the second Join code would be to create this result? My first view works fine, but I don't know how to join it to the second table to achieve this result? I didn't make the tables, I just have to work with what I was given. Thanks in advance!

  • attaching linq to sql datacontext to httpcontext in business layer

    - by rap-uvic
    Hello all, I need my linq to sql datacontext to be available across my business/data layer for all my repository objects to access. However since this is a web app, I want to create and destroy it per request. I'm wondering if having a singleton class that can lazily create and attach the datacontext to current HttpContext would work. My question is: would the datacontext get disposed automatically when the request ends? Below is the code for what I'm thinking. Would this accomplish my purpose: have a thread-safe datacontext instance that is lazily available and is automatically disposed when the request ends? public class SingletonDC { public static NorthwindDataContext Default { get { NorthwindDataContext defaultInstance = (NorthwindDataContext)System.Web.HttpContext.Current.Items["datacontext"]; if (defaultInstance == null) { defaultInstance = new NorthwindDataContext(); System.Web.HttpContext.Current.Items.Add("datacontext", defaultInstance); } return defaultInstance; } } }

  • LINQ to SQL SubmitChangess() progress

    - by Emir
    I'm using LINQ to SQLto import old DBF files into MSSQL. I'm reading all rows and adding them to database using ctx.MyTable.InsertOnSubmit(row) After reading phase is completed I have around 100 000 pending inserts. ctx.SubmitChanges() naturally is taking a long time. Is there any way to track progress of the ctx.submitchanges()? Can ctx.Log somehow be used for this purpose? Update: Is it possible to use ctx.GetChangeSet().Inserts.Count and track insert statements using the Log? Dividing ctx.SubmitChanges() into smaller chunks is not working for me, because I need transaction, all or nothing. Update 2: I've found nice class ActionTextWriter using which I will try to count inserts. http://damieng.com/blog/2008/07/30/linq-to-sql-log-to-debug-window-file-memory-or-multiple-writers

  • SQL Get Top 10 records by date

    - by Pselus
    I have a table full of bugs. The BugTitle is the page erroring and I also capture the error line. I would like to build an SQL Query that selects the top 10 bugs based on bugtitle and error line. I have this query: SELECT COUNT(BugTitle) AS BugCount, BugTitle, ErrLine FROM Bugs WHERE BugDate >= DateAdd(Day, -30, DateDiff(Day, 0, GetDate())) GROUP BY BugTitle, ErrLine ORDER BY BugCount, ErrLine DESC But I'm not sure if it's correct. I'm pretty sure that my test data only has 1 bug that happens on the same line but that's not showing up with this query. Can anyone help?

  • SQL Query in Ruby: Only select the changes

    - by JJ Liu
    Suppose I have a table (PriceHistory) like this, every time I change anything in the row, I will record the whole row again in the table. id | buy_price | sell_price | change_date 1 | 2 | 2 | 2012-06-22 2 | 3 | 2 | 2012-06-20 3 | 2 | 6 | 2012-06-15 4 | 5 | 5 | 2012-06-15 5 | 5 | 7 | 2012-06-15 6 | 4 | 8 | 2012-06-12 I only care about the change of BuyPrice, Is there a way to just select row 1, 2, 3, & 5? Here is the Ruby code I come up with, but it does not only select the changed rows PriceHistory.select("id, BuyPrice, change_date"). order("change_date DESC") Both Ruby and SQL answers are fine.

  • varchar comparison in SQL Server

    - by Ram
    I am looking for some SQL varchar comparison function like C# string.compare (we can ignore case for now, should return zero when the character expression are same and a non zero expression when they are different) Basically I have some alphanumeric column in one table which needs to be verified in another table. I cannot do select A.col1 - B.col1 from (query) as "-" operator cannot be applied on character expressions I cannot cast my expression as int (and then do a difference/subtraction) as it fails select cast ('ASXT000R' as int) Conversion failed when converting varchar 'ASXT000R' to int Soundex would not do it as soundex is same for 2 similar strings Difference would not do it as select difference('abc','ABC') = 4 (as per msdn, difference is the difference in the soundex of 2 character expressions and difference =4 implies least different) Is there any other way of doing it ?

  • possible to create sql query with table wildcards?

    - by Rees
    this is probably a simple question, but i have been unable to find a solution online, any help would be much appreciated. I'm trying to create an SQL query in PHP and would like to somehow apply a wild card to the TABLE filter... something perhaps like.... select * from %table%. However, I have only so far been able to see filters for column values not table names. as an example i would have tables such as: jan_table_1 feb_table_1 jan_table_2 feb_table_2 and would want to say, select only tables with a "jan" prefix... or "1" suffix. Is there a quick and easy solution to this that I have not seen? Thanks in advance!

  • LINQ-to-SQL Query Timing Out

    - by kevinw
    I'm running this query in LINQ: var unalloc = db.slot_sp_getUnallocatedJobs("Repair", RadComboBox1.SelectedValue, 20); It runs when I first open the page, but when I go back to it and try to run the same query with a different value, "Con", being passed through, the linq to sql designer.cs tells me that I've got a timeout error. Any ideas? Edit: This is what's in the designer: [Function(Name="dbo.slot_sp_getUnallocatedJobs")] Public ISingleResult<slot_sp_getUnallocatedJobsResult> slot_sp_getUnallocatedJobs([Parameter(Name="JobType", DbType="VarChar(20)")] string jobType, [Parameter(Name="Contract", DbType="VarChar(10)")] string contract, [Parameter(Name="Num", DbType="Int")] System.Nullable<int> num) { IExecuteResult result = this.ExecuteMethodCall(this, ((MethodInfo)(MethodInfo.GetCurrentMethod())), jobType, contract, num); return ((ISingleResult<slot_sp_getUnallocatedJobsResult>)(result.ReturnValue)); } } This is the error: SQLException was unhandled by user code Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.

  • Converting SQL statement into Linq

    - by DMan
    I'm trying to convert the following to a LINQ to SQL statement in C#. Can anyone give me a hand? Basically my table keeps record of all history of changes such that the created date max date for each seedlot is the most recent record and the correct one to show. SELECT reports.* FROM [dbo].[Reports] reports WHERE reports.createdDate IN ( SELECT MAX(report_max_dates.createdDate) FROM [dbo].[Reports] report_max_dates GROUP BY report_max_dates.Lot ) So far this is what I have. var result = (from report in db.Reports where report.createdDate == (from report_max in db.Reports group report_max by report_max.Lot into report_max_grouped select report_max_grouped).Max() select report); I can't figure out how to get the MAX dates for all reports and how to do an IN statement on the report.createdDate.

  • GetOleDbSchemaTable Foreign Keys on Sql Server 2005

    - by haxelit
    I'm trying to get the Foreign Keys for a table in my SQL Server 2005 database. I'm using the GetOleDbSchemaTable function right now: DataTable schemaTable = connection.GetOleDbSchemaTable( OleDbSchemaGuid.Foreign_Keys, new object[] { null, null, null, "TABLE" }); This pulls back the right foreign keys, the only problem is that the UpdateRule and DeleteRule are set to "No Action". If I browse to the same table in SSMS I can see that my DeleteRule is "Set NULL". Does the GetOleDbSchemaTable function not return the proper foreign key rules ? Has any one else ran into this problem ?

  • SQL Like question

    - by mike
    Is there a way to reverse the SQL Like operator so it searches a field backwards? For example, I have a value in a field that looks like this "Xbox 360 Video Game". If I write a query like below, it returns the result fine. SELECT id FROM table WHERE title like "%Xbox%Game%" However, when I search like this, it doesn't find any results. SELECT id FROM table WHERE title like "%Video%Xbox%" I need it to match in any direction. How can I get around this?

  • LINQ to SQL Web Application Best Practices

    - by derek
    In my experience building web applications, I've always used a n-tier approach. A DAL that gets data from the db and populates the objects, and BLL that gets objects from the DAL and performs any business logic required on them, and the website that gets it's display data from the BLL. I've recently started learning LINQ, and most of the examples show the queries occurring right from the Web Application code-behinds(it's possible that I've only seen overly simplified examples). In the n-tier architectures, this was always seen as a big no-no. I'm a bit unsure of how to architect a new Web Application. I've been using the Server Explorer and dbml designer in VS2008 to create the dbml and object relationships. It seems a little unclear to me if the dbml would be considered the DAL layer, if the website should call methods within a BLL, which then would do the LINQ queries, etc. What are some general architecture best practices, or approaches to creating a Web Application solution using LINQ to SQL?

  • Potential for SQL injection here?

    - by Matt Greer
    This may be a really dumb question but I figure why not... I am using RIA Services with Entity Framework as the back end. I have some places in my app where I accept user input and directly ask RIA Services (and in turn EF and in turn my database) questions using their data. Do any of these layers help prevent security issues or should I scrub my data myself? For example, whenever a new user registers with the app, I call this method: [Query] public IEnumerable<EmailVerificationResult> VerifyUserWithEmailToken(string token) { using (UserService userService = new UserService()) { // token came straight from the user, am I in trouble here passing it directly into // my DomainService, should I verify the data here (or in UserService)? User user = userService.GetUserByEmailVerificationToken(token); ... } } (and whether I should be rolling my own user verification system is another issue altogether, we are in the process of adopting MS's membership framework. I'm more interested in sql injection and RIA services in general)

  • Linq To Sql: Compiled Queries and Extension Methods

    - by Beni
    Hi community, I'm interessted, how does Linq2Sql handles a compiled query, that returns IQueryable. If I call an extension method based on a compiled query like "GetEntitiesCompiled().Count()" or "GetEntitiesCompiled().Take(x)". What does Linq2Sql do in the background? This would be very bad, so in this situation I should write a compiled query like "CountEntitiesCompiled". Does he load the result (in this case "GetEntitiesCompiled()") into the memory (mapped to the entity class like "ToList()")? So what situations make sense, when the compiled queries return IQueryable, that query is not able to modify, before request to the Sql-Server. So in my opinion I can just as good return List. Thanks for answers!

  • MS Sql Full-text search vs. LIKE expression

    - by Marks
    Hi. I'm currently looking for a way to search a big database (500MB - 10GB or more on 10 tables) with a lot of different fields(nvarchars and bigints). Many of the fields, that should be searched are not in the same table. An example: A search for '5124 Peter' should return all items, that ... have an ID with 5124 in it, have 'Peter' in the title or description have item type id with 5124 in it created by a user named 'peter' or a user whose id has 5124 in it created by a user with '5124' or 'peter' in his street address. How should i do the search? I read that the full-text search of MS-Sql is a lot more performant than a query with the LIKE keyword and i think the syntax is more clear, but i think it cant search on bigint(id) values and i read it has performance problems with indexing and therefore slows down inserts to the DB. In my project there will be more inserting than reading, so this could be a matter. Thanks in advance, Marks
