  • Stored proc executes >30 secs when called from website, but <1 sec when called from ssms

    - by Blootac
    I have a stored procedure that is called by a website to display data. Today the web page has started timing out so I got profiler going and saw the query that was taking too long. I then ran the same query in management studio, under the same user login, and it takes less than a second to return. Is there anything obvious that could be causing this? I can't think of a reason why when ASP calls the stored proc it takes 30 secs but when I call it it's fine. Thanks

  • Set a class for an element in a PHP include()

    - by paracaudex
    I have an identical horizontal menu at the top of all of my pages, which I add using a PHP include() statement. In my stylesheet I want to have a class where if the user is on a particular page, the menu item corresponding to that page will have a different color. So, more or less: #dropdown { background-color:blue; } #dropdown .active { background-color:green; } But, since the menu comes from the PHP include, it's always the same. How can I write some PHP or JavaScript that adds class="active" to the appropriate menu item for each page?

  • Pre-load audio files at the client-side for later use

    - by awj
    I'm building an online test which implements audio (mp3) using the native audio player (i.e. non Flash-based). The test shows one question at a time and loads each subsequent question asynchronously. Some questions have an accompanying audio file, others don't, and the audio files can be several MB in size. So what I'm hoping to do is to preload the audio files client-side at the start of the test and then move these into place when the relevant question comes up. So far I've tried loading an audio file into a QuickTime player, then when that question comes up I use jQuery's clone(true) method to copy this into a part of the page which is displayed. However, when I do this the QuickTime player has to reload the audio file from source. Same is true for Windows Media Player. Does anyone have any suggestions as to how I can preload the audio client-side and then call it forward when needed?

  • Time to start a counter on client-side.

    - by Felipe
    Hi everybody, I'm developing an web application using asp.net mvc, and i need to do a stopwatch (chronometer) (with 30 seconds preprogrammed to start in a certain moment) on client-side using the time of the server, by the way, the client's clock can't be as the server's clock. So, i'm using Jquery to call the server by JSon and get the time, but it's very stress because each one second I call the server to get time, something like this: $(function() { GetTimeByServer(); }); function GetTimeByServer() { $.getJSon('/Home/Time', null, function(result) { if (result.SecondsPending < 30) { // call another function to start an chronometer } else { window.SetTimeout(GetTimeByServer, 1000); //call again each 1 second! } }); } It works fine, but when I have more than 3 or 4 call like this, the browser slowly but works! I'd like to know, how improve more performace in client side, or if is there any way to do this... is there any way to client listen the server like a "socket" to know if the chronometer should start... PS: Sorry for my english! thanks Cheers

    - by The King
    Hi.. I have 3 tables similar to the sctructure below CREATE TABLE [dbo].[EmpBasic]( [EmpID] [int] IDENTITY(1,1) NOT NULL Primary Key, [Name] [varchar](50), [Address] [varchar](50) ) CREATE TABLE [dbo].[EmpProject]( [EmpID] [int] NOT NULL primary key, // referencing column with EmpBasic [EmpProject] [varchar](50) ) CREATE TABLE [dbo].[EmpFull_Temp]( [ObjectID] [int] IDENTITY(1,1) NOT NULL Primary Key, [T1Name] [varchar](50) , [T1Address] [varchar](50) , [T1EmpProject] [varchar](50) ) The EmpFull_Temp table has the records with a dummy object ID column... I want to populate the first 2 tables with the records in this table... But with EmpID as a reference between the first 2 tables. I tried this in a stored procedure... Create Table #IDSS (EmpID bigint, objID bigint) Insert into EmpBasic output Inserted.EmpID, EmpFull_Temp.ObjectID into #IDSS Select T1Name, T1Address from EmpFull_Temp Where ObjectID < 106 Insert into EmpProject Select A.EmpID, B.T1EmpProject from #IDSS as A, EmpFull_Temp as B Where A.ObjID = B.ObjectID But it says.. The multi-part identifier "EmpFull_Temp.ObjectID" could not be bound. Could you please help me in achieving this...

  • Implementing the server side of Webhooks

    - by Howiecamp
    If I want to Webhooks-enable a web application (I'm referring to the server-side of things, ie the server where the event happens and the callback is initiated from), are there libraries for this, or is this functionality typically part of the web server stack? Or, am I looking at this incorrectly, and to implement Webhooks I simply code my application to do an HTTP POST callback based on whatever events I care about?

What I am looking for is a walkthrough of how to get SqlExpress2008 included in the same manner. Second choice would be how to get (or make) a MergeModule (MSM) file to do the same.

  • Why do updates inside of a SQL transaction still need disk IO?

    - by usr
    In SQL Profiler you can see that very simple updates to a table by primary key take about 10-30ms each. On about every 10th update the write column shows 1, on all other updates it shows 0. This must mean that about every 10th update statement still requires disk IO. I wonder why that is. Would it not be more efficient queue up all IO until the transaction commits?

  • SQL aggregation query, grouping by entries in junction table

    - by cm007
    I have TableA in a many-to-many relationship with TableC via TableB. That is, TableA TableB TableC id | val fkeyA | fkeyC id | data I wish the do select sum(val) on TableA, grouping by the relationship(s) to TableC. Every entry in TableA has at least one relationship with TableC. For example, TableA 1 | 25 2 | 30 3 | 50 TableB 1 | 1 1 | 2 2 | 1 2 | 2 2 | 3 3 | 1 3 | 2 should output 75 30 since rows 1 and 3 in Table have the same relationships to TableC, but row 2 in TableA has a different relationship to TableC. How can I write a SQL query for this?

  • BULK INSERT from one table to another all on the server

    - by steve_d
    I have to copy a bunch of data from one database table into another. I can't use SELECT ... INTO because one of the columns is an identity column. Also, I have some changes to make to the schema. I was able to use the export data wizard to create an SSIS package, which I then edited in Visual Studio 2005 to make the changes desired and whatnot. It's certainly faster than an INSERT INTO, but it seems silly to me to download the data to a different computer just to upload it back again. (Assuming that I am correct that that's what the SSIS package is doing). Is there an equivalent to BULK INSERT that runs directly on the server, allows keeping identity values, and pulls data from a table? (as far as I can tell, BULK INSERT can only pull data from a file) Edit: I do know about IDENTITY_INSERT, but because there is a fair amount of data involved, INSERT INTO ... SELECT is kinda of slow. SSIS/BULK INSERT dumps the data into the table without regards to indexes and logging and whatnot, so it's faster. (Of course creating the clustered index on the table once it's populated is not fast, but it's still faster than the INSERT INTO...SELECT that I tried in my first attempt) Edit 2: The schema changes include (but are not limited to) the following: 1. Splitting one table into two new tables. In the future each will have its own IDENTITY column, but for the migration I think it will be simplest to use the identity from the original table as the identity for the both new tables. Once the migration is over one of the tables will have a one-to-many relationship to the other. 2. Moving columns from one table to another. 3. Deleting some cross reference tables that only cross referenced 1-to-1. Instead the reference will be a foreign key in one of the two tables. 4. Some new columns will be created with default values. 5. Some tables aren’t changing at all, but I have to copy them over due to the "put it all in a new DB" request.

  • Unexpected behaviour of Order by clause

    - by Newbie
    I have a table which looks like Col1 col2 col3 col4 col5 1 5 1 4 6 1 4 0 3 7 0 1 5 6 3 1 8 2 1 5 4 3 2 1 4 The script is declare @t table(col1 int, col2 int, col3 int,col4 int,col5 int) insert into @t select 1,5,1,4,6 union all select 1,4,0,3,7 union all select 0,1,5,6,3 union all select 1,8,2,1,5 union all select 4,3,2,1,4 If I do a sorting (ascending), the output is Col1 col2 col3 col4 col5 0 1 5 6 3 1 4 0 3 7 1 5 1 4 6 1 8 2 1 5 4 3 2 1 4 The query is Select * from @t order by col1,col2,col3,col4,col5 But as can be seen that the sorting output is wrong (col2 to col5). I want the output to be every column being sorted in ascending order i.e. Col1 col2 col3 col4 col5 0 1 0 1 3 1 3 1 1 4 1 4 2 3 5 1 5 2 4 6 4 8 5 6 7 Why so and how to overcome this? Thanks in advance

  • Watermarking Flash Videos (server-side)

    - by Roberto Aloi
    Hi all, I have a bunch of flash videos that I need to watermark with user related information, to make illegal re-distribution of these files harder. I'm wondering how can this be done server-side. If done client-side, it will be quite easy for the user to intercept the videos before they are watermarked. Since the watermark should contain user-specific information I can't really watermark the videos before encoding them (unless I have an encoded video per user - not feasible). I'm expecting this to affect the streaming performances a lot, though. Any idea how this can be done (possibly in an efficient way)?

  • Optimizing T-SQL where an array would be nice

    - by Polatrite
    Alright, first you'll need to grab a barf bag. I've been tasked with optimizing several old stored procedures in our database. This SP does the following: 1) cursor loops through a series of "buildings" 2) cursor loops through a week, Sunday-Saturday 3) has a huge set of IF blocks that are responsible for counting how many Objects of what Types are present in a given building Essentially what you'll see in this code block is that, if there are 5 objects of type #2, it will increment @Type_2_Objects_5 by 1. IF @Number_Type_1_Objects = 0 BEGIN SET @Type_1_Objects_0 = @Type_1_Objects_0 + 1 END IF @Number_Type_1_Objects = 1 BEGIN SET @Type_1_Objects_1 = @Type_1_Objects_1 + 1 END IF @Number_Type_1_Objects = 2 BEGIN SET @Type_1_Objects_2 = @Type_1_Objects_2 + 1 END IF @Number_Type_1_Objects = 3 BEGIN SET @Type_1_Objects_3 = @Type_1_Objects_3 + 1 END [... Objects_4 through Objects_20 for Type_1] IF @Number_Type_2_Objects = 0 BEGIN SET @Type_2_Objects_0 = @Type_2_Objects_0 + 1 END IF @Number_Type_2_Objects = 1 BEGIN SET @Type_2_Objects_1 = @Type_2_Objects_1 + 1 END IF @Number_Type_2_Objects = 2 BEGIN SET @Type_2_Objects_2 = @Type_2_Objects_2 + 1 END IF @Number_Type_2_Objects = 3 BEGIN SET @Type_2_Objects_3 = @Type_2_Objects_3 + 1 END [... Objects_4 through Objects_20 for Type_2] In addition to being extremely hacky (and limited to a quantity of 20 objects), it seems like a terrible way of handling this. In a traditional language, this could easily be solved with a 2-dimensional array... objects[type][quantity] += 1; I'm a T-SQL novice, but since writing stored procedures often uses a lot of temporary tables (which could essentially be a 2-dimensional array) I was wondering if someone could illuminate a better way of handling a situation like this with two dynamic pieces of data to store. Requested in comments: The columns are simply Number_Type_1_Objects, Number_Type_2_Objects, Number_Type_3_Objects, Number_Type_4_Objects, Number_Type_5_Objects, and CurrentDateTime. Each row in the table represents 5 minutes. The expected output is to figure out what percentage of time a given quantity of objects is present throughout each day. Sunday - Object Type 1 0 objects - 69 rows, 5:45, 34.85% 1 object - 85 rows, 7:05, 42.93% 2 objects - 44 rows, 3:40, 22.22% On Sunday, there were 0 objects of type 1 for 34.85% of the day. There was 1 object for 42.93% of the day, and 2 objects for 22.22% of the day. Repeat for each object type.
