  • How to invert rows and columns using a T-SQL Pivot Table

    - by Jeff Stock
    I have a query that returns one row. However, I want to invert the rows and columns, meaning show the rows as columns and columns as rows. I think the best way to do this is to use a pivot table, which I am no expert in. Here is my simple query: SELECT Period1, Period2, Period3 FROM GL.Actuals WHERE Year = 2009 AND Account = '001-4000-50031' Results (with headers): Period1, Period2, Period3 612.58, 681.36, 676.42 I would like for the results to look like this: Desired Results: Period, Amount Period1, 612.58 Period2, 681.36 Period3, 676.42 This is a simple example, but what I'm really after is a bit more comlex than this. I realize I could produce theses results by using several SELECT commands instead. I'm just hoping someone can shine some light on how to accomplish this with a Pivot Table or if there is yet a better way.

  • Getting the ranking of a photo in SQL

    - by Jake Petroules
    I have the following tables: Photos [ PhotoID, CategoryID, ... ] PK [ PhotoID ] Categories [ CategoryID, ... ] PK [ CategoryID ] Votes [ PhotoID, UserID, ... ] PK [ PhotoID, UserID ] A photo belongs to one category. A category may contain many photos. A user may vote once on any photo. A photo can be voted for by many users. I want to select the ranks of a photo (by counting how many votes it has) both overall and within the scope of the category that photo belongs to. The count of SELECT * FROM Votes WHERE PhotoID = @PhotoID being the number of votes a photo has. I want the resulting table to have generated columns for overall rank, and rank within category, so that I may order the results by either. So for example, the resulting table from the query should look like: PhotoID VoteCount RankOverall RankInCategory 1 48 1 7 3 45 2 5 19 33 3 1 2 17 4 3 7 9 5 5 ... ...you get the idea. How can I achieve this? So far I've got the following query to retrieve the vote counts, but I need to generate the ranks as well: SELECT PhotoID, UserID, CategoryID, DateUploaded, (SELECT COUNT(CommentID) AS Expr1 FROM dbo.Comments WHERE (PhotoID = dbo.Photos.PhotoID)) AS CommentCount, (SELECT COUNT(PhotoID) AS Expr1 FROM dbo.PhotoVotes WHERE (PhotoID = dbo.Photos.PhotoID)) AS VoteCount, Comments FROM dbo.Photos

  • Linq-to-Sql query advice please

    - by Mantorok
    Hi all Just wondering if this is a good approach, I need to search for items containing all of the specified keywords in a space-delimted string, is this the right approach this? var result = (from row in DataContext.PublishedEvents join link in DataContext.PublishedEvent_EventDateTimes on row.guid equals link.container join time in DataContext.EventDateTimes on link.item equals time.guid orderby row.EventName select new {row, time}); // Split the keyword(s) to limit results with all of those words in. foreach(var keyword in request.Title.Split(" ".ToCharArray(), StringSplitOptions.RemoveEmptyEntries)) { var val = keyword; result = result.Where(row=>row.row.EventName.Contains(val)); } var end = result.Select(row=>new EventDetails { Title = row.row.EventName, Description = TrimDescription(row.row.Description), StartDate = row.time.StartDate, EndDate = row.time.EndDate, Url = string.Format(ConfigurationManager.AppSettings["EventUrl"], row.row.guid) }); response.Total = end.Count(); response.Result = end.ToArray(); Is there a slick Linq-way of doing all of this in one query? Thanks

    I am trying to get data from my Database of those who have upcoming birth days in next few days(declared earlier) it's working fine for days but this query will not work if i add 24 days to current date cause than it will need change in month. i wonder how can i do it declare @date int=10, @month int=0 select * from STUDENT_INFO where DATEPART(DD,STDNT_DOB) between DATEPART(DD,GETDATE()) and DATEPART(DD,DATEADD(DD,@date,GETDATE())) and DATEPART(MM,STDNT_DOB) = DATEPART(MM,DATEADD(MM,@month,GETDATE())) This query works fine but it only checks date between 8 & 18 but if i use it like this declare @date int=30, @month int=0 select * from STUDENT_INFO where DATEPART(DD,STDNT_DOB) between DATEPART(DD,GETDATE()) and DATEPART(DD,DATEADD(DD,@date,GETDATE())) and DATEPART(MM,STDNT_DOB) = DATEPART(MM,DATEADD(MM,@month,GETDATE())) it will return nothing since it require addition in month as well If I Use it like this declare @date int=40, @month int=0 select * from STUDENT_INFO where DATEPART(DD,STDNT_DOB) between DATEPART(DD,GETDATE()) and DATEADD(DD,@date,GETDATE()) and DATEPART(MM,STDNT_DOB) = DATEPART(MM,DATEADD(MM,@month,GETDATE())) than it will return results till the last of this month but will not show till 18/12 which was required

  • SQL Server connection identification

    - by andrew007
    Hi, I have several developers which connect to production and test servers where we have DBs with similar names and structures. In SSMS there are info related to the connection, but sometimes are not properly displayed and/or hidden. I know that it is possible to customize the status bar of each connection in SSMS, but how do you ensure that your developer is connecting to the right server before he runs a query? Is there any way to handle this? THANKS!

  • Don't display dynamic query in result

    - by Tom Andrews
    Hi all, Is it possible to hide a dynamic query from the result sets provided from a Stored Procedure? I am using the @@rowcount of the dynamic query to set a variable that is used to determine whether another query runs or not. The other query is used by code that I cannot change - hence why I am changing the Stored Procedure. The dynamic query returns as the first result set from the Stored Procedure is now the result of the dynamic query which currently is "breaking" the calling code. Thanks in advance

  • Whats wrong with my SQL query?

    - by William
    I'm trying to set up a query that shows the first post of each thread and is ordered by the date of the last post in each thread. I got the first part down with this query: SELECT * FROM ( SELECT Min( ID ) AS MinID FROM test_posts GROUP BY Thread )tmin JOIN test_posts ON test_posts.ID = tmin.MinID Now I need to figure out how to call the last post of each thread into a table, than use that table to order the first tables results. So far I got this, but it doesn't work. SELECT * FROM ( SELECT Min( ID ) AS MinID FROM test_posts GROUP BY Thread )tmin JOIN test_posts ON test_posts.ID = tmin.MinID ORDER BY (SELECT MAX( ID ) AS MaxID, Thread, MAX( Date ) FROM test_posts GROUP BY Thread )tmax tmax.Date

  • Can this be done with single SQL query

    - by Ghostrider
    I'm using MySQL. I have a table Type SubType 1 1 1 5 1 6 1 8 2 2 2 3 3 1 3 2 3 3 For each type there is some number of subtypes. For every subtype in a type there is a corresponding subtype in the next type: (1,1) => (2,2) (1,5) => (2,3) (1,6) => (2,2) (1,8) => (2,3) (2,2) => (3,1) (2,3) => (3,2) In case you haven't seen the pattern, here it is: you sort both current and next types by subtype, then in the next type you get subtype in the same position as your current subtype in current type is. If there are more subtypes in the current type that in the next one, you warp around and start from the first subtype in the next type. Is it possible to construct a query that takes current type and subtype and returns corresponding subtype in the next type?

  • Simplest way to use a DatagridView with Linq to SQL

    - by Martín Marconcini
    Hi, I have never used datagrids and such, but today I came across a simple problem and decided to "databind" stuff to finish this faster, however I've found that it doesn't work as I was expecting. I though that by doing something as simple as: var q = from cust in dc.Customers where cust.FirstName == someString select cust; var list = new BindingList<Customer>(q.ToList()); return list; Then using that list in a DataGridView1.DataSource was all that I needed, however, no matter how much I google, I can't find a decent example on how to populate (for add/edit/modify) the results of a single table query into a DataGridView1. Most samples talk about ASP.NET which I lack, this is WinForms. Any ideas? I've came across other posts and the GetNewBindingList, but that doesn't seem to change much. What am I missing (must be obvious)? Thanks in advance. Martin.

  • How to join table to itself and select max values in SQL

    - by Jakub Konop
    I have a contracts table: contractId date price partId 1 20120121 10 1 2 20110130 9 1 3 20130101 15 2 4 20110101 20 2 The contract with greatest date being the active contract (don't blame me, I blame infor for creating xpps) I need to create query to see only active contracts (one contract per part, the contract with highest date). So the result of the query should be like this: contractId date price partId 1 20120121 10 1 3 20130101 15 2 I am out of ideas here, I tried self joining the table, I tried aggregation functions, but I can't figure it out. If anyone would have any idea, please share them with me..

  • Bulletproof way to DROP and CREATE a database under Continuous Integration.

    - by H. Abraham Chavez
    I am attempting to drop and recreate a database from my CI setup. But I'm finding it difficult to automate the dropping and creation of the database, which is to be expected given the complexities of the db being in use. Sometimes the process hangs, errors out with "db is currently in use" or just takes too long. I don't care if the db is in use, I want to kill it and create it again. Does some one have a straight shot method to do this? alternatively does anyone have experience dropping all objects in the db instead of dropping the db itself? USE master --Create a database IF EXISTS(SELECT name FROM sys.databases WHERE name = 'mydb') BEGIN ALTER DATABASE mydb SET SINGLE_USER --or RESTRICTED_USER --WITH ROLLBACK IMMEDIATE DROP DATABASE uAbraham_MapSifterAuthority END CREATE DATABASE mydb;

  • SQL Server stored procedure return code oddity

    - by gbn
    Hello The client that calls this code is restricted and can only deal with return codes from stored procs. So, we modified our usual contract to RETURN -1 on error and default to RETURN 0 if no error If the code hits the inner catch block, then the RETURN code default to -4. Where does this come from, does anyone know...?

  • Sql query: use where in or foreach?

    - by phenevo
    Hi, I'm using query, where the piece is: ...where code in ('va1','var2'...') I have about 50k of this codes. It was working when I has 30k codes, but know I get: The query processor ran out of internal resources and could not produce a query plan. This is a rare event and only expected for extremely complex queries or queries that reference a very large number of tables or partition I think that problem is related with IN... So now I'm planning use foreach(string code in codes) ...where code =code Is it good Idea ??

  • Removing duplicate SQL records to permit a unique key

    - by j pimmel
    I have a table ('sales') in a MYSQL DB which should have rightfully have had a unique constraint enforced to prevent duplicates. To first remove the dupes and set the constraint is proving a bit tricky. Table structure (simplified): 'id (unique, autoinc)' product_id The goal is to enforce uniqueness for product_id. The de-duping policy I want to apply is to remove all duplicate records except the most recently created, eg: the highest id Or to put another way, I would like to delete duplicate records, excluding the ids matched by the following query: select id from sales s inner join (select product_id, max(id) as maxId from sales group by product_id having count(product_id) > 1) groupedByProdId on s.product_id and s.id = groupedByProdId.maxId I've struggled with this on two fronts - writing the query to select the correct records to delete and then also the constraint in MYSQL where a subselect FROM clause of a DELETE cannot reference the same table from which data is being removed.
