  • linq2sql left join with "multiselect"

    - by just_azho
    Hi, folks I'm trying to achieve following by linq2sql, but not successful. I've Member and Reference tables. DB is design in such a manner that Member can have multiple (=0) References. What I want as a result of query is, list (rows) of members, where all references of the member are "collected" in one column. What I had achieved is following query, but for this one there exist a row for each Reference. var refs = (from m in db.Members join r in db.References on m.PID equals r.PID into g from o in g.DefaultIfEmpty() select new { member = m, name = (o == null ? "" : o.NameSurname) }); I feel I need to insert SelectMany somewher :) Could you please give hints on achieving the goal?

  • SQL change "like" to "contains"

    - by Paul
    products table (mySQL) record_id categories (comma-delimited list) --------- -------------------------------- 1 960|1,957|1,958|1 I have the following dynamic query (simplified for the purposes of this question). The query is passed specified categories, each in the format xxxx|yyyy, and I need to return products having the passed category in its comma-delimited list of categories. The current query looks like: select p.* from products p where (p.categories like '%27|0%' or p.categories like '%972|1%' or p.categories like '%969|1%') But, the LIKE clause sometimes permits anomalies. I would like to write the query more like: select p.* from products p where (p.categories contains '27|0' or p.categories contains'972|1' or p.categories contains '969|1') How would I do this?

  • Aggregate SQL column values by time period

    - by user305688
    I have some numerical data that comes in every 5 minutes (i.e. 288 values per day, and quite a few days worth of data). I need to write a query that can return the sums of all values for each day. So currently the table looks like this: 03/30/2010 00:01:00 -- 553 03/30/2010 00:06:00 -- 558 03/30/2010 00:11:00 -- 565 03/30/2010 00:16:00 -- 565 03/30/2010 00:21:00 -- 558 03/30/2010 00:26:00 -- 566 03/30/2010 00:31:00 -- 553 ... And this goes on for 'x' number of days, I'd like the query to return 'x' number of rows, each of which containing the sum of all the values on each day. Something like this: 03/30/2010 -- <sum> 03/31/2010 -- <sum> 04/01/2010 -- <sum> The query will go inside a Dundas webpart, so unfortunately I can't write custom user functions to assist it. All the logic needs to be in just the one big query. Any help would be appreciated, thanks. I'm trying to get it to work using GROUP BY and DATEPART at the moment, not sure if it's the right way to go about it.

  • FreeText COUNT query on multiple tables is super slow

    - by Eric P
    I have two tables: **Product** ID Name SKU **Brand** ID Name Product table has about 120K records Brand table has 30K records I need to find count of all the products with name and brand matching a specific keyword. I use freetext 'contains' like this: SELECT count(*) FROM Product inner join Brand on Product.BrandID = Brand.ID WHERE (contains(Product.Name, 'pants') or contains(Brand.Name, 'pants')) This query takes about 17 secs. I rebuilt the FreeText index before running this query. If I only check for Product.Name. They query is less then 1 sec. Same, if I only check the Brand.Name. The issue occurs if I use OR condition. If I switch query to use LIKE: SELECT count(*) FROM Product inner join Brand on Product.BrandID = Brand.ID WHERE Product.Name LIKE '%pants%' or Brand.Name LIKE '%pants%' It takes 1 secs. I read on MSDN that: http://msdn.microsoft.com/en-us/library/ms187787.aspx To search on multiple tables, use a joined table in your FROM clause to search on a result set that is the product of two or more tables. So I added an INNER JOINED table to FROM: SELECT count(*) FROM (select Product.Name ProductName, Product.SKU ProductSKU, Brand.Name as BrandName FROM Product inner join Brand on product.BrandID = Brand.ID) as TempTable WHERE contains(TempTable.ProductName, 'pants') or contains(TempTable.BrandName, 'pants') This results in error: Cannot use a CONTAINS or FREETEXT predicate on column 'ProductName' because it is not full-text indexed. So the question is - why OR condition could be causing such as slow query?

  • How can an SQL query return data from multiple tables

    - by Fluffeh
    I would like to know how to get data from multiple tables in my database, what types of methods are there to do this, what are joins and unions and how are they different from one another? When should I use each one compared to the others? I am planning to use this in my (for example - PHP) application, but don't want to run multiple queries against the database, what options do I have to get data from multiple tables in a single query? Note: I am writing this as I would like to be able to link to a well written guide on the numerous questions that I constantly come across in the PHP queue, so I can link to this for further detail when I post an answer. The answers cover off the following: Part 1 - Joins and Unions Part 2 - Subqueries Part 3 - Tricks and Efficient Code

  • SQL Query, return value from table with no join

    - by jdenomme19
    I'm hoping for an idea on the best way to approach what I'm trying to do. I have a table with a list of transactions. Each transactions has a PostDate in DateTime format. I have another table holding the fiscal period values. This table has the following columns; FiscalYear, FiscalMonth, StartDate, EndDate. I'm trying to write a query that will return all values from my transactions table, along with the FiscalYear and FiscalMonth of the PostDate. So I guess I'm just trying to return the FiscalYear and FiscalMonth values when the PostDate falls between the StartDate and EndDate. I've tried using a Subbuery, but I have little experience with them and kept returning an error message that the subquery was returning more than 1 value. Help would be appreciated SELECT Transactions.PostDate, Transactions.TranKey, Transactions.CustKey, (SELECT FiscalPeriod.FiscPer FROM FiscalPeriod WHERE (Transactions.PostDate > CONVERT(Datetime, FiscalPeriod.StartDate, 102)) AND (Transactions.PostDate < CONVERT(DATETIME, FiscalPeriod.EndDate, 102))) AS FisPer FROM Transactions

  • Question about inserting/updating rows with SQL Server (ASP.NET MVC)

    - by Alex
    I have a very big table with a lot of rows, every row has stats for every user for certain days. And obviously I don't have any stats for future. So to update the stats I use UPDATE Stats SET Visits=@val WHERE ... a lot of conditions ... AND Date=@Today But what if the row doesn't exist? I'd have to use INSERT INTO Stats (...) VALUES (Visits=@val, ..., Date=@Today) How can I check if the row exists or not? Is there any way different from doing the COUNT(*)? If I fill the table with empty cells, it'd take hundreds of thousands of rows taking megabytes and storing no data.

  • SQL and/or LINQ query for determining daily increases in viewers

    - by Gio
    We're montioring usage of a certain resources by monitoring users logins (We can see user logins growing daily). After filtering out repeat inter day logins for users, we'd like to track the # of users using the service each day, and then using that info to determine overall incremental gains for each calendar day. Our table is pretty simple: class ServiceLogin { String login; DateTime loginTime; }

  • How can I do a left outer join where both tables have a where clause?

    - by cdeszaq
    Here's the scenario: I have 2 tables: CREATE TABLE dbo.API_User ( id int NOT NULL, name nvarchar(255) NOT NULL, authorization_key varchar(255) NOT NULL, is_active bit NOT NULL ) ON [PRIMARY] CREATE TABLE dbo.Single_Sign_On_User ( id int NOT NULL IDENTITY (1, 1), API_User_id int NOT NULL, external_id varchar(255) NOT NULL, user_id int NULL ) ON [PRIMARY] What I am trying to return is the following: is_active for a given authorization_key The Single_Sign_On_User.id that matches the external_id/API_User_id pair if it exists or NULL if there is no such pair When I try this query: SELECT Single_Sign_On_User.id, API_User.is_active FROM API_User LEFT OUTER JOIN Single_Sign_On_User ON Single_Sign_On_User.API_User_id = API_User.id WHERE Single_Sign_On_User.external_id = 'test_ext_id' AND API_User.authorization_key = 'test' where the "test" API_User record exists but the "test_ext_id" record does not, and with no other values in either table, I get no records returned. When I use: SELECT Single_Sign_On_User.id, API_User.is_active FROM API_User LEFT OUTER JOIN Single_Sign_On_User ON Single_Sign_On_User.API_User_id = API_User.id WHERE API_User.authorization_key = 'test' I get the results I expect (NULL, 1), but that query doesn't allow me to find the "test_ext_id" record if it exists but would give me all records associated with the "test" API_User record. How can I get the results I am after?

  • check for null date in CASE statement, where have I gone wrong?

    - by James.Elsey
    Hello, My source table looks like this Id StartDate 1 (null) 2 12/12/2009 3 10/10/2009 I want to create a select statement, that selects the above, but also has an additional column to display a varchar if the date is not null such as : Id StartDate StartDateStatus 1 (null) Awaiting 2 12/12/2009 Approved 3 10/10/2009 Approved I have the following in my select, but it doesn't seem to be working. All of the statuses are set to Approved even though the dates have some nulls select id, StartDate, CASE StartDate WHEN null THEN 'Awaiting' ELSE 'Approved' END AS StartDateStatus FROM myTable The results of my query look like : Id StartDate StartDateStatus 1 (null) Approved 2 12/12/2009 Approved 3 10/10/2009 Approved 4 (null) Approved 5 (null) Approved StartDate is a smalldatetime, is there some exception to how this should be treated? Thanks

  • sql select from a large number of IDs

    - by Claudiu
    I have a table, Foo. I run a query on Foo to get the ids from a subset of Foo. I then want to run a more complicated set of queries, but only on those IDs. Is there an efficient way to do this? The best I can think of is creating a query such as: SELECT ... --complicated stuff WHERE ... --more stuff AND id IN (1, 2, 3, 9, 413, 4324, ..., 939393) That is, I construct a huge "IN" clause. Is this efficient? Is there a more efficient way of doing this, or is the only way to JOIN with the inital query that gets the IDs? If it helps, I'm using SQLObject to connect to a PostgreSQL database, and I have access to the cursor that executed the query to get all the IDs.
