  • Sql: simultaneous aggregate from two tables

    - by Ash
    I have two tables: a Files table, which includes the file type, and a File Properties table, which references the file table via a foreign key. Sample Files table: | id | name | type | --------------------- | 1 | file1 | zip | | 2 | file2 | zip | | 3 | file3 | zip | | 4 | file4 | jpg | And the Properties table: | file_id | property | ----------------------- | 1 | x | | 2 | x | I want to make a query, which shows the count of each file type, and how many files of that type have a property. So in the example, the result would be | type | filecount | prop count | ---------------------------------- | zip | 3 | 2 | | jpg | 1 | 0 | I could accomplish this by select f.type, (select count(id) from files where type = f.type), count(fp.id) from files as f, file_properties as fp where f.id = fp.file_id group by f.type; But this seems very suboptimal and is very slow. Any better way to do this?

  • How to remove duplicate records in a table?

    - by Mason Wheeler
    I've got a table in a testing DB that someone apparently got a little too trigger-happy on when running INSERT scripts to set it up. The schema looks like this: ID UNIQUEIDENTIFIER TYPE_INT SMALLINT SYSTEM_VALUE SMALLINT NAME VARCHAR MAPPED_VALUE VARCHAR It's supposed to have a few dozen rows. It has about 200,000, most of which are duplicates in which TYPE_INT, SYSTEM_VALUE, NAME and MAPPED_VALUE are all identical and ID is not. Now, I could probably make a script to clean this up that creates a temporary table in memory, uses INSERT .. SELECT DISTINCT to grab all the unique values, TRUNCATE the original table and then copy everything back. But is there a simpler way to do it, like a DELETE query with something special in the WHERE clause?

  • Using SQL to get the Last Reply on a Post

    - by Anraiki
    I am trying to replicate a forum function by getting the last reply of a post. For clarity, see PHPBB: there are four columns, and the last column is what I like to replicate. I have my tables created as such: discussion_id (primary key) user_id parent_id comment status pubdate I was thinking of creating a Link Table that would update for each time the post is replied to. The link table would be as follow: discussion_id (primary key) last_user_id last_user_update However, I am hoping that theres a advance query to achieve this method. That is, grabbing each Parent Discussion, and finding the last reply in each of those Parent Discussions. Am I right that there is such a query?

  • error handling in asp.net

    - by user98454
    Hi How can i pass the different types of errors from Data access layer to presentation layer? suppose if we take the northwind database scenario I want to delete the customer, so i selected one customer in ui and clicked the "delete" button.It internally calls the "delete" in data access layer. The prerequisite for deleting the customer is that the customer doesn't have any orders.So in data access layer we wil check whether that customer has any orders.If the customer has orders how can we pass the message from dal to presentation layer that the customer has orders and we don't delete. Am i doing right?is there any other ways to deal with this type? Thanks in advance

  • Keeping Linq to SQL alive when using ViewModels (ASP.NET MVC)

    - by Kohan
    I have recently started using custom ViewModels (For example, CustomerViewModel) public class CustomerViewModel { public IList<Customer> Customers{ get; set; } public int ProductId{ get; set; } public CustomerViewModel(IList<Customer> customers, int productId) { this.Customers= customers; this.ProductId= productId; } public CustomerViewModel() { } } ... and am now passing them to my view instead of the Entities themselves (for example, var Custs = repository.getAllCusts(id) ) as it seems good practice to do so. The problem i have encountered is that when using ViewModels; by the time it has got to the the view i have lost the ability to lazy load on customers. I do not believe this was the case before using them. Is it possible to retain the ability of Lazy Loading while still using ViewModels? Or do i have to eager load using this method? Thanks, Kohan.

  • Inserting Strings Without Trailing Spaces SQL

    - by Soo
    I have a database with a field named Field1 that has 100 nchars per entry. Each time I add a value, it is stored as: "value (100-ValueLength Spaces) " So Basically each stored value has a string of spaces after it. This is getting to be an issue when I try doing: if (value == "Example") because of all of the empty spaces after the string. How can I get it so the stored values don't have all of these trailing spaces?

  • script to dynamically fix ophaned users after db restore

    - by JJgates
    After performing a database restore, I want to run a dynamic script to fix ophaned users. My script below loops through all users that are displayed after executing sp_change_users_login 'report' and apply "alter user [username] with login = [username]" to fix SID conflicts verses static go statements. Although, I'm getting an "incorrect syntax error on line 15." can't figure out why... DECLARE @Username varchar(100), @cmd varchar(100) DECLARE userLogin_cursor CURSOR FAST_FORWARD FOR SELECT UserName = name FROM sysusers WHERE issqluser = 1 and (sid IS NOT NULL AND sid <> 0×0) AND suser_sname(sid) IS NULL ORDER BY name FOR READ ONLY OPEN userLogin_cursor FETCH NEXT FROM userLogin_cursor INTO @Username WHILE @@fetch_status = 0 BEGIN SET @cmd = ‘ALTER USER ‘+@username+‘ WITH LOGIN ‘+@username EXECUTE(@cmd) FETCH NEXT FROM userLogin_cursor INTO @Username END CLOSE userLogin_cursor DEALLOCATE userLogin_cursor

  • Help with Oracle SQL Count function! =)

    - by user363024
    Hi guys.. The question im struggling with is this: i have a list of helicopter names in different charters and i need to find out WHICH helicopter has the least amount of charters booked. Once i find that out i need to ONLY display the one that has the least. I so far have this: SELECT Helicopter_Name COUNT (Distinct Charter_NUM) FROM Charter_Table GROUP BY Helicopter Name ^ this is where i am stuck, i realise MIN could be used to pick out the value that is the smallest but i am not sure how to integrate this into the command. Something like Where MIN = MIN Value Id really appreciate it

  • SQL, problem with OrderBy / GroupBy

    - by Tristan
    Hi, In my table I have two fields among others : article_id and *version* *example: article_id : 5 // version 1 aricle_id: 5 // version 2 article_id: 6 // version 1* What i want to do is to retrieve the latest version for each article id (in my example i want to retrieve the article 5 version 2 object and article 6 and version 1 object).

  • How to prompt user input parameters for SQL Queries in Access 2010

    - by user1848907
    SELECT Transactions.TransactionNumber FROM Transactions WHERE (((Transactions.Date)>=#11/23/12#)) AND (((Transactions.Date)<=#11/23/12#)); The above code returns all the transaction that happened between the specified dates. But I want those dates to be defined by the user every time the query is executed. I tried using the [] operators to have the user define the criteria in the WHERE, something like this: WHERE (((Transactions.Date)>=[Input a Date])) AND (((Transactions.Date)<=[Input a Date])); But microsoft Access throws a Syntax error message. The same happens when I include the # (date operators) like this WHERE (((Transactions.Date)>=#[Input a Date]#)) AND (((Transactions.Date)<=#[Input a Date]#)); Is there anopther way to manage dates that I'm not aware of or is asking a user for dates in a query out of the question

  • SQL Server Reporting Services Bar Chart

    - by Avitus
    I am trying to create horizontal bar chart to look like a pill chart. I would like to take a either a stacked bar chart or a 100% stacked bar chart and put rounded ends onto this chart. I would only be using 1 row within the chart. One idea I had was just putting rounded images on either end of the chart to accomplish this but I'm not sure that this will give the smooth feel of a single pill. Does anyone have a good suggestion? I am not tied to the idea of using a chart object. But I would prefer to stay away from third party components that need to be purchased.

  • SQL IF ELSE with output params stored proc help

    - by Kettenbach
    Hi All, I have a stored proc (SS2008) that takes a couple int ids and needs to look up if they exist in a table before adding a record. I have an int output param I would like to return and set its value based on what occrured. I have this so far, but it always returns 1. Can someone point me in the right direction?

    I'd like to do had a dynamic number of one start/end time pairs passed to a function as an input parameter. The function would then use the list instead of just one start, and one end time in a select statement. CREATE FUNCTION [dbo].[GetData] ( @StartTime datetime, @EndTime datetime ) RETURNS int AS BEGIN SELECT @EndTime = CASE WHEN @EndTime > CURRENT_TIMESTAMP THEN CURRENT_TIMESTAMP ELSE @EndTime END DECLARE @TempStates TABLE (StartTime datetime NOT NULL , EndTime datetime NOT NULL , StateIdentity int NOT NULL ) INSERT INTO @TempStates SELECT StartTime , EndTime , StateIdentity FROM State WHERE StartTime <= @EndTime AND EndTime >= @StartTime RETURN 0 END

  • Can't get DataGridView to refresh over Linq to SQL (WinForm)

    - by GringoFrenzy
    Very strange situation here: I'm using L2S to populate a DataGridView. Code follows: private void RefreshUserGrid() { var UserQuery = from userRecord in this.DataContext.tblUsers orderby userRecord.DisplayName select userRecord; UsersGridView.DataSource = UserQuery; //I have also tried //this.UserBindingSource.DataSource = UserQuery; //UsersGridView.Datasource = UserBindingSource; UsersGridView.Columns[0].Visible = false; } Whenever I use L2S to Add/Delete records from the database, the GridView refreshes perfectly well. However, if someone is editing the grid and makes a mistake, I want them to be able to hit a refresh button and have their mistakes erased by reloading from the datasource. For the life of me, I can't get it to work. The code I am currently using on my refresh button is this: private void button1_Click(object sender, EventArgs e) { this.DataContext.Refresh(RefreshMode.OverwriteCurrentValues); RefreshUserGrid(); } But the damn GridView remains unaffected. All that happens is the selected row becomes unselected. I have tried .Refresh(), .Invalidate(), I've tried changing the DataSource to NULL and back again (all suggestions from similar posts here)....none of it works. The only time the Grid refreshes is if I restart the app. I must be missing something fundamental, but I'm totally stumped and so are my colleagues. Any ideas? Thanks!
