  • SQL Group by Minute- Expanded

    - by Barnie
    I am working on something similar to this post here: TS SQL - group by minute However mine is pulling from an message queue, and I need to see an accurate count of the amount of traffic the Message Queue is creating/ sending, and at what time Select * From MessageQueue mq My expanded version of this though is the following: A) User defines a start time and an end time (Easy enough using Declare's @StartTime and @EndTime B) Give the user the option of choosing the "grouping". Will it be broken out by 1 minutes, 5 minutes, 15 minutes, or 30 minutes (Max). (I had thought to do this with a CASE statement, but my test problems fall apart on me.) C) Display the data to accurately show a count of what happened during the interval (Grouping) selected. This is where I am at so far SQL Blob: DECLARE @StartTime datetime DECLARE @EndTime datetime SELECT DATEPART(n, mq.cre_date)/5 as Time --Trying to just sort by 5 minute intervals ,CONVERT(VARCHAR(10),mq.Cre_Date,101) ,COUNT(*) as results FROM dbo.MessageQueue mq WHERE mq.cre_date BETWEEN @StartDate AND @EndDate GROUP BY DATEPART(n, mq.cre_date)/5 --Trying to just sort by 5 minute intervals , eq.Cre_Date This is the output I would like to achieve: [Time] [Date] [Message Count] 1300 06/26/2012 5 1305 06/26/2012 1 1310 06/26/2012 100

  • UPDATE from SELECT complains about more that one value returned

    - by Álvaro G. Vicario
    I have this data structure: request ======= building_id lot_code building ======== building_id lot_id lot === lot_id lot_code The request table is missing the value for the building_id column and I want to fill it in from the other tables. So I've tried this: UPDATE request SET building_id = ( SELECT bu.building_id FROM building bu INNER JOIN lot lo ON bu.lot_id=lo.lot_id WHERE lo.lot_code = request.lot_code ); But I'm getting this error: Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , , = or when the subquery is used as an expression. Is it due to wrong syntax? The data model allows more than one building per lot but actual data doesn't contain such cases so there should be at most one building_id per lot_code.

  • Append Results from two queries and output as a single table.

    - by tHeSiD
    I have two queries that I have to run, I cannon join them But their resultant tables have the same structrure. For example I have select * from products where producttype=magazine select * from products where producttype = book I have to combine the result of these two queries, and then output it as one single result. I have to do this inside a stored procedure. PS These are just examples I provided, i have a complex table structure. The main thing is I cannot join them.

  • Why does MS SQL Mgmt Studio Express keep forgetting my passwords?

    - by Ryan
    I have about had it with this tool, I check the save password box at the login dialogue but it just doesn't work. Sometimes it will for a few days, and then the password will just be gone. Nearly every time I load this thing up I have to track down the password again and type it in. Is there some password rule in the database that would be causing this? This is driving me absolutely crazy.

  • Firefox Does NOT get local site cookie

    - by Campo
    This is a weird one. We have a production server (Server 2008) and two staging servers (Server 2008 and Server 2003) I have sites on all of these. They all use cookies. On the Production server when browsing to our site www.supernovainteractive.com there is a cookie that detects when you visted the site and it will not refresh the logo animation (top left hand side) on clicking to another page. This works for all browsers on the production server. I’m not sure what’s going on but for some reason cookies are not working on one site in the 2008 staging server only. This is when browsing using Firefox (3.6.3) they work fine on all other browsers (IE, Chrome, Safari, Opera) In addition, the 2003 staging server works fine. You can test on the Supernova Interactive site by noticing the logo in the top left corner. It uses a cookie to detect if you’ve already seen the animation. Once you’ve seen it once, it doesn’t animate again until tomorrow. Currently, it’s animating every time. I have opened an outside facing port so others can see the issue. Http://exchange.supernova.com:10009 Any ideas on this one? Firewalls are off on the server. Notice you do not get a cookie from Exchange.supernova.com.

  • Sub Query making Query slow.

    - by Muhammad Kashif Nadeem
    Please copy and paste following script. DECLARE @MainTable TABLE(MainTablePkId int) INSERT INTO @MainTable SELECT 1 INSERT INTO @MainTable SELECT 2 DECLARE @SomeTable TABLE(SomeIdPk int, MainTablePkId int, ViewedTime1 datetime) INSERT INTO @SomeTable SELECT 1, 1, DATEADD(dd, -10, getdate()) INSERT INTO @SomeTable SELECT 2, 1, DATEADD(dd, -9, getdate()) INSERT INTO @SomeTable SELECT 3, 2, DATEADD(dd, -6, getdate()) DECLARE @SomeTableDetail TABLE(DetailIdPk int, SomeIdPk int, Viewed INT, ViewedTimeDetail datetime) INSERT INTO @SomeTableDetail SELECT 1, 1, 1, DATEADD(dd, -7, getdate()) INSERT INTO @SomeTableDetail SELECT 2, 2, NULL, DATEADD(dd, -6, getdate()) INSERT INTO @SomeTableDetail SELECT 3, 2, 2, DATEADD(dd, -8, getdate()) INSERT INTO @SomeTableDetail SELECT 4, 3, 1, DATEADD(dd, -6, getdate()) SELECT m.MainTablePkId, (SELECT COUNT(Viewed) FROM @SomeTableDetail), (SELECT TOP 1 s2.ViewedTimeDetail FROM @SomeTableDetail s2 INNER JOIN @SomeTable s1 ON s2.SomeIdPk = s1.SomeIdPk WHERE s1.MainTablePkId = m.MainTablePkId) FROM @MainTable m Above given script is just sample. I have long list of columns in SELECT and around 12+ columns in Sub Query. In my From clause there are around 8 tables. To fetch 2000 records full query take 21 seconds and if I remove Subquiries it just take 4 seconds. I have tried to optimize query using 'Database Engine Tuning Advisor' and on adding new advised indexes and statistics but these changes make query time even bad. Note: As I have mentioned that this is test data to explain my question the real data has lot of tables joins columns but without Sub-Query the results us fine. Any help thanks.

  • Ordering sql query results

    - by user343409
    My sql query gives the columns: product_id (which is an integer) pnl (which is float - can be negative) I get more than 100 rows. I want to filter out the top 40 rows based on abs(pnl). But the results should be ordered by pnl column only and not by abs(pnl). I want to do this for MSSQL 2005. Is there a way to do this?

  • Software automation testing

    - by dotnet-practitioner
    I work in a .net shop where we need to automate software testing. We write ASP.net web apps, web services, windows services, scheduled console application. Back end for all these applications is SQL Server. We would like to automate testing of any bug fixes, any where from web UI change to, middle tier .net code change to sql code change. This tool would be used by programmers to do unit test and played back in different test environments to ensure that bug fix is test correctly in all the environments including the produciton environment. This test would be executed by different teams such as QA, Build, and production site testers. What tool or approach do you recommend?

  • Modeling many-to-one with constraints?

    - by Greg Beech
    I'm attempting to create a database model for movie classifications, where each movie could have a single classification from each of one of multiple rating systems (e.g. BBFC, MPAA). This is the current design, with all implied PKs and FKs: TABLE Movie ( MovieId INT ) TABLE ClassificationSystem ( ClassificationSystemId TINYINT ) TABLE Classification ( ClassificationId INT, ClassificationSystemId TINYINT ) TABLE MovieClassification ( MovieId INT, ClassificationId INT, Advice NVARCHAR(250) -- description of why the classification was given ) The problem is with the MovieClassification table whose constraints would allow multiple classifications from the same system, whereas it should ideally only permit either zero or one classifications from a given system. Is there any reasonable way to restructure this so that a movie having exactly zero or one classifications from any given system is enforced by database constraints, given the following requirements? Do not duplicate information that could be looked up (i.e. duplicating ClassificationSystemId in the MovieClassification table is not a good solution because this could get out of sync with the value in the Classification table) Remain extensible to multiple classification systems (i.e. a new classification system does not require any changes to the table structure)? Note also the Advice column - each mapping of a movie to a classification needs to have a textual description of why that classification was given to that movie. Any design would need to support this.

  • Efficiently select top row for each category in the set

    - by VladV
    I need to select a top row for each category from a known set (somewhat similar to this question). The problem is, how to make this query efficient on the large number of rows. For example, let's create a table that stores temperature recording in several places. CREATE TABLE #t ( placeId int, ts datetime, temp int, PRIMARY KEY (ts, placeId) ) -- insert some sample data SET NOCOUNT ON DECLARE @n int, @ts datetime SELECT @n = 1000, @ts = '2000-01-01' WHILE (@n>0) BEGIN INSERT INTO #t VALUES (@n % 10, @ts, @n % 37) IF (@n % 10 = 0) SET @ts = DATEADD(hour, 1, @ts) SET @n = @n - 1 END Now I need to get the latest recording for each of the places 1, 2, 3. This way is efficient, but doesn't scale well (and looks dirty). SELECT * FROM ( SELECT TOP 1 placeId, temp FROM #t WHERE placeId = 1 ORDER BY ts DESC ) t1 UNION ALL SELECT * FROM ( SELECT TOP 1 placeId, temp FROM #t WHERE placeId = 2 ORDER BY ts DESC ) t2 UNION ALL SELECT * FROM ( SELECT TOP 1 placeId, temp FROM #t WHERE placeId = 3 ORDER BY ts DESC ) t3 The following looks better but works much less efficiently (30% vs 70% according to the optimizer). SELECT placeId, ts, temp FROM ( SELECT placeId, ts, temp, ROW_NUMBER() OVER (PARTITION BY placeId ORDER BY ts DESC) rownum FROM #t WHERE placeId IN (1, 2, 3) ) t WHERE rownum = 1 The problem is, during the latter query execution plan a clustered index scan is performed on #t and 300 rows are retrieved, sorted, numbered, and then filtered, leaving only 3 rows. For the former query three times one row is fetched. Is there a way to perform the query efficiently without lots of unions?

  • Copy new records from datatable and identify changes in old records

    - by Betite
    Assume there are two tables: Remote_table and My_table. Remote_table has 6 columns: **PROJECT JOB_TYPE MONTH YEAR** HOURS IS_DELETED 134393 70 1 2013 30 0 134393 70 2 2013 50 0 134393 70 3 2013 80 0 134393 70 10 2012 10 0 134393 70 11 2012 0 0 134393 70 12 2012 15 0 My_table is a copy of remote_table. I tried to copy only the new records from the remote_table by this query: SELECT * FROM [remote_DB].[LudanProjectManager].[dbo].Remote_table EXCEPT SELECT * FROM My_table It works OK but I get a duplicate primary key exception when changes have been made on the remote_table on the hours column. Can anyone think of a way to copy only the new records from remote_table and if changes has been made on old records, to identify them and update the my_table to correspond?

  • What is the most effective and flexible way to generate combinations in TSQL?

    - by SDReyes
    What is the most effective and flexible way to generate combinations in TSQL? With 'Flexible', I mean you should be able to add easily combination rules. e.g.: to generate combinatories of 'n' elements, sorting, remove duplicates, get combinatories where each prize belongs to a different lottery, etc. For example, Having a set of numbers representing lottery prizes. Number | Position | Lottery --------------------------- 12 | 01 | 67 12 | 02 | 67 34 | 03 | 67 43 | 01 | 89 72 | 02 | 89 33 | 03 | 89 (I include the position column because, a number could be repeated among different lottery's prizes) I would like to generate combinatories like: Numbers | Lotteries ------------------- 12 12 | 67 67 12 34 | 67 67 12 34 | 67 67 12 43 | 67 89 12 72 | 67 89 12 33 | 67 89 . . .

  • batch - append either date/time of creation or random to end of filename

    - by Maclovin
    Hi Damsel in distress needing help with a batch-script. I have a bunch of files that one system creates. Either in one of 2 directories, or in the directory above that. The naming is apparently not very important, so It's a bit random. 2 questions for you batch-geniuses out there. a) How can I append date/time of creation to the end of the filename with a batch-script? b) How can I append a random filename (so I make the files unique) with a batch-script? Thanks in advance, dudes and dudettes. Yours sincerely, the Maclovin!

    Hello, I have MSSQL 2008 Ent and OLTP database with two big tables. How I can move this tables to another filegroup without service interrupting? Now, about 100-130 records inserted and 30-50 records updated each second in this tables. Each table have about 100M records and six fields (including one field geography). I looking for solution via google, but all solutions contain "create second table, insert rows from first table, drop first table, bla bla bla". Can I use partitioning functions for solving this problem? Thank you.

  • Pivot to obtain EAV data

    - by Snowy
    I have an EAV table (simple key/value in every row) and I need to take the 'value' from two of the rows and concat them into a single row with a single column. I can't seem to get through the part where I just have the pivot straight. Can anyone help me figure this out? Declare @eavHelp Table ( [Key] VARCHAR (8) NOT NULL, [Value] VARCHAR (8) NULL ) Insert Into @eavHelp Values ( 'key1' , 'aaa' ) Insert Into @eavHelp Values ( 'key2' , 'bbb' ) Select * From @eavHelp Pivot ( Min( [Value] ) For [Value] in ( hmm1 , hmm2 ) ) as Piv Where [Key] = 'key1' or [Key] = 'key2' That makes: Key hmm1 hmm2 -------- -------- -------- key1 NULL NULL key2 NULL NULL But what I want to make is: hmmmX ----- aaa;bbb

  • How can I improve my select query for storing large versioned data sets?

    - by Jason Francis
    At work, we build large multi-page web applications, consisting mostly of radio and check boxes. The primary purpose of each application is to gather data, but as users return to a page they have previously visited, we report back to them their previous responses. Worst-case scenario, we might have up to 900 distinct variables and around 1.5 million users. For several reasons, it makes sense to use an insert-only approach to storing the data (as opposed to update-in-place) so that we can capture historical data about repeated interactions with variables. The net result is that we might have several responses per user per variable. Our table to collect the responses looks something like this: CREATE TABLE [dbo].[results]( [id] [bigint] IDENTITY(1,1) NOT NULL, [userid] [int] NULL, [variable] [varchar](8) NULL, [value] [tinyint] NULL, [submitted] [smalldatetime] NULL) Where id serves as the primary key. Virtually every request results in a series of insert statements (one per variable submitted), and then we run a select to produce previous responses for the next page (something like this): SELECT t.id, t.variable, t.value FROM results t WITH (NOLOCK) WHERE t.userid = '2111846' AND (t.variable='internat' OR t.variable='veteran' OR t.variable='athlete') AND t.id IN (SELECT MAX(id) AS id FROM results WITH (NOLOCK) WHERE userid = '2111846' AND (t.variable='internat' OR t.variable='veteran' OR t.variable='athlete') GROUP BY variable) Which, in this case, would return the most recent responses for the variables "internat", "veteran", and "athlete" for user 2111846. We have followed the advice of the database tuning tools in indexing the tables, and against our data, this is the best-performing version of the select query that we have been able to come up with. Even so, there seems to be significant performance degradation as the table approaches 1 million records (and we might have about 150x that). We have a fairly-elegant solution in place for sharding the data across multiple tables which has been working quite well, but I am open for any advice about how I might construct a better version of the select query. We use this structure frequently for storing lots of independent data points, and we like the benefits it provides. So the question is, how can I improve the performance of the select query? I assume the nested select statement is a bad idea, but I have yet to find an alternative that performs as well. Thanks in advance. NB: Since we emphasize creating over reading in this case, and since we never update in place, there doesn't seem to be any penalty (and some advantage) for using the NOLOCK directive in this case.
