• Sum of XML duration elements in SQL2008

  - by Matt

  I have a XML column that holds information about my games. Here's a sample of the information looks like. <game xmlns="http://my.name.space" > <move> <player>PlayerA</player> <start movetype="Move">EE5</start> <end movetype="Move">DF6</end> <movetime>PT1S</movetime> </move> <move> <player>PlayerB</player> <start movetype="Move">CG7</start> <end movetype="Move">DE6</end> <movetime>PT3S</movetime> </move> <move> <player>PlayerA</player> <start movetype="Move">FD3</start> <end movetype="Move">EG8</end> <movetime>PT4S</movetime> </move> </game> I'm trying to design an XML query to take the sum of my movetime element. Basically I need the sum of each players move time. So using the above sample, PlayerA would have a total move time of 5 seconds and PlayerB would have a total move time of 3 seconds. Here's the XML query that I've been currently been working with SELECT GameHistory.query('declare default element namespace "http://my.name.space"; data(/game/move/movetime)') AS Value FROM GamesWHERE Id=560 I'm a newbie to XSLT / XPATH functions :P

• MSSQL Efficiently dropping a group of rows with millions and millions of rows

  - by Net Citizen

  I recently asked this question: http://stackoverflow.com/questions/2519183/ms-sql-share-identity-seed-amongst-tables (Many people wondered why) I have the following layout of a table: Table: Stars starId bigint categoryId bigint starname varchar(200) But my problem is that I have millions and millions of rows. So when I want to delete stars from the table Stars it is too intense on MS SQL. I cannot use built in partitioning for 2005+ because I do not have an enterprise license. When I do delete though, I always delete a whole category Id at a time. I thought of doing a design like this: Table: Star_1 starId bigint CategoryId bigint constaint rock=1 starname varchar(200) Table: Star_2 starId bigint CategoryId bigint constaint rock=2 starname varchar(200) In this way I can delete a whole category and hence millions of rows in O(1) by doing a simple drop table. My question is, is it a problem to have thousands of tables in your MS SQL? The drop in O(1) is extremely desirable to me. Maybe there's a completely different solution I'm not thinking of?

• Making a DateTime field in SQLExpress database?

  - by Mike

  I'm putting together a simple test database to learn MVC with. I want to add a DateTime field to show when the record was CREATED. ID = int Name = Char DateCreated = (dateTime, DateTime2..?) I have a feeling that this type of DateTime capture can be done automatically - but that's all I have, a feeling. Can it be done? And if so how? While we're on the subject: if I wanted to include another field that captured the DateTime of when the record was LAST UPDATED how would I do that. I'm hoping to not do this manually. Many thanks Mike

• dynamically creating the #temp table and then used to insert the data

  - by praveen

  Hi All, I am importing an intermediate result of query into a temp table for further use, so I used a #temp table to maintain the same schema as select * into # temp from schema.tableName where 1<1; insert into # temp from exec(table) While I am doing this statement as a variable to pass the different tableName its not working SET @TEMPSCHEMA = 'SELECT * INTO #temp FROM ' + @PKSchema + '.dbo.' + @PKTableName + ' WHERE 1<1;' exec(@TEMPSCHEMA) INSERT INTO #temp EXEC ( @SELECTSTATEMENT ) however after exec statement it is not taking the values to the temp table. it is showing the invalid object id #temp

• Getting filtered results with subquery

  - by josepv

  I have a table with something like the following: ID Name Color 1 Bob Blue 2 John Yellow 1 Bob Green 3 Sara Red 3 Sara Green What I would like to do is return a filtered list of results whereby the following data is returned: ID Name Color 1 Bob Blue 2 John Yellow 3 Sara Red i.e. I would like to return 1 row per user. (I do not mind which row is returned for the particular user - I just need that the [ID] is unique.) I have something already that works but is really slow where I create a temp table adding all the ID's and then using a "OUTER APPLY" selecting the top 1 from the same table, i.e. CREATE TABLE #tb ( [ID] [int] ) INSERT INTO #tb select distinct [ID] from MyTable select T1.[ID], T2.[Name], T2.Color from #tb T1 OUTER APPLY ( SELECT TOP 1 * FROM MyTable T2 WHERE T2.[ID] = T1.[ID] ) AS V2 DROP TABLE #tb Can somebody suggest how I may improve it? Thanks

• Database with users design

  - by 1110

  I am in database design development phase. Application will work with large number of users (LARGE :)) I designed 80% of database but I have one Users table which is connected to everything else: Users {UserId, FirstName, LastName, Username, Password, PasswordQuestion, PasswordAnswer, Gender, RoleId, LastLoginDate etc etc} I saw asp.net membership database structure where Users and Membership are two tables. My questions are: Should I use one users table with all users data in it or more tables? If answer is 'more tables', what tables to use? Any advice on how to structure relation between those tables? This is sample relation that I have, and trying to improve. I don't understand why user and userChild are separated tables?

• Best Practices - Stored Procedure Logging

  - by hgulyan

  If you have a long running SP, do you log somehow it's actions or just wait for this message? "Command(s) completed successfully." I assume, that there can be plenty solutions on this subject, but is there any best practice - a simple solution that is frequently used? EDIT I've found an interesting link on this subject http://weblogs.sqlteam.com/brettk/archive/2006/09/21/12391.aspx Article describes using a log table, but there's an issue The logging procedure must be executed outside of any transaction I can't call that insert outside, because of cursor that I use and insert a line to that table on every row. Any ideas?

  hi all, can any one tell how to tell svn that these files are to be deleted from repository through command line. i am using cruise control to automate the svn commit process. but the execution of svn commit command restores the files which i deleted from my working copy. the way i am doing is. 1. delete some files in my working copy.( no. of files in my WC is less than no. of files in repository) 2. execute svn command using cruise control. <exec executable="svn.exe"> <buildArgs>ci -m "test msg" --no-auth-cache --non-interactive</buildArgs> <buildTimeoutSeconds>1000</buildTimeoutSeconds> </exec> result: the deleted files are restored in my WC... Can someone help me in figuring out where i have gone wrong... or if i have to do some changes / configurations... thank u all. regards. uday

• Skipping one item in the column

  - by zurna

  I created a simple news website. I store both videos and images in IMAGES table. Videos added have videos and images added have images stored in a column called ImagesType. Images and Videos attached to a news is stored in ImagesID column of the NEWS table. My problem occurs when I need to display the first image of a news. i.e. IMAGES table: ImagesID ImagesLgURL ImagesType 1 /FLPM/media/videos/0H7T9C0F.flv videos 2 /FLPM/media/images/8R5D7M8O.jpg images 3 /FLPM/media/images/0E7Q9Z0C.jpg images NEWS table NewsID ImagesID NewsTitle 1 1;2; Street Chic: Paris ERROR 2 3; Paris Runway NO ERROR The following code give me an error with the 2nd news item because the first ImageID stored in the list is not an image but a video. I need to figure out a way to skip the video item and display the next image. I hope I made sense. SQL = "SELECT NEWSID, CATEGORIESID, IMAGESID, NEWSTITLE, NEWSSHORTDESC, NEWSACTIVE, NEWSDATEENTERED" SQL = SQL & " FROM NEWS N" SQL = SQL & " WHERE NEWSACTIVE = 1" SQL = SQL & " ORDER BY NEWSDATEENTERED DESC" Set objNews = objConn.Execute(SQL) Do While intLooper1 <= 3 And Not objNews.EOF IMAGES = Split(Left(objNews("IMAGESID"),Len(objNews("IMAGESID"))-1), ";") SQL = "SELECT ImagesID, ImagesName, ImagesLgURL, ImagesSmURL, ImagesType" SQL = SQL & " FROM IMAGES I" SQL = SQL & " WHERE ImagesID = " & IMAGES(0) & " AND ImagesType = 'images'" Set objLgImage = objConn.Execute(SQL) <div> <a href="?Section=news&SubSection=redirect&NEWSID=<%=objNews("NEWSID")%>"> <img src="<%=objLgImage("ImagesLgURL")%>" alt="<%=objLgImage("ImagesName")%>" /> </a> </div> <% objLgImage.Close Set objLgImage = Nothing intLooper1 = intLooper1 + 1 objNews.MoveNext Loop %>

• How can I select values from different rows depending on the most recent entry date, all for the sam

  - by user321185

  Basically I have a table which is used to hold employee work wear details. It is formed of the columns: EmployeeID, CostCentre, AssociateLevel, IssueDate, TrouserSize, TrouserLength, TopSize & ShoeSize. An employee can be assigned a pair of trousers, a top and shoes at the same time or only one or two pieces of clothing. As we all know peoples sizes and employee levels can change which is why I need help really. Different types of employees (associatelevels) require different colours of clothing but you can ignore this part. Everytime an employee receives an item of clothing a new row will be inserted into the table with an input date. I need to be able to select the most recent clothes size for each item of clothing for each employee. It is not necessary for all the columns to hold values because an employee could receive trousers or poloshirts at different times in the year. So for example if employee '54664LSS' was given a pair of 'XL' trousers and a 'L' top on 24/03/11 but then received a 'M' top on 26/05/10. The input of these items would be help on two different rows obviously. So if I wanted to select the most recent clothing for each clothes category. Then the values of the 'M' sized top and the 'L' sized trousers would need to be returned. Any help would be greatly appreciated as I'm pretty stuck :(. Thanks.

• Inserting "null" (literally) in to a stored procedure parameter.

  - by Nazadus

  I'm trying to insert the word "Null" (literally) in to a parameter for a stored procedure. For some reason SqlServer seems to think I mean NULL and not "Null". If I do a check for IF @LastName IS NULL // Test: Do stuff Then it bypasses that because the parameter isn't null. But when I do: INSERT INTO Person (<params>) VALUES (<stuff here>, @LastName, <more stuff here>); // LastName is 'Null' It bombs out saying that LastName doesn't accept nulls. I would seriously hate to have this last name, but someone does... and it's bombing the application. We're using SubSonic 2.0 (yeah, it's fairly old but upgrading is painful) as our DAL and stepping through it, I see it does create the parameters properly (for what I can tell). I've tried creating a temp table to see if I could replicate it manually but it seems to work just fine. Here is the example I create: DECLARE @myval VARCHAR(50) SET @myval = 'Null' CREATE TABLE #mytable( name VARCHAR(50)) INSERT INTO #mytable VALUES (@myval) SELECT * FROM #mytable DROP table #mytable Any thoughts on how I can fix this?

• Is it possible to use ContainsTable to get results for more than one column?

  - by LockeCJ

  Consider the following table: People FirstName nvarchar(50) LastName nvarchar(50) Let's assume for the moment that this table has a full-text index on it for both columns. Let's suppose that I wanted to find all of the people named "John Smith" in this table. The following query seems like a perfectly rational way to accomplish this: SELECT * from People p INNER JOIN CONTAINSTABLE(People,*,'"John*" AND "Smith*"') Unfortunately, this will return no results, assuming that there is no record in the People table that contains both "John" and "Smith" in either the FirstName or LastName columns. It will not match a record with "John" in the FirstName column, and "Smith" in the LastName column, or vice-versa. My question is this: How does one accomplish what I'm trying to do above? Please consider that the example above is simplified. The real table I'm working with has ten columns and the input I'm receiving is a single string which is split up based on standard word breakers (space, dash, etc.)

• SQL to retrieve aggregated data with computed columns

  - by Remnant

  I have a table that looks like this for about ~30 students: StudentID Course* CourseStatus 1 Math Pass 1 English Fail 1 Science Pass 2 Math Fail 2 English Pass 2 Science Fail etc. *In my actual database the 'Course' column is a CourseID e.g. (1 = Math; 2 = English etc.) which references a 'CourseName' table. I amended the table above just to make it clear the nature of the problem. I want to write a query (stored procedure) in SQL that summarises performance for a given course and returns the following: EXEC usp_GetCourseSummary 'Math' Total Students Total Pass % Pass Total Fail % Fail 25 15 60 10 40 Have been scratching my head on this one for some time. Any ideas?

• Isn't INT more efficient than UNIQUEIDENTIFIER?

  - by ck

  I have a parent table and child table where the columns that join them together are the UNIQUEIDENTIFIER type. The child table has a clustered index on the column that joins it to the parent table (its PK, which is also clustered). I have created a copy of both of these tables but changed the relationship columns to be INTs instead, have rebuilt the indexes so that they are essentially the same structure and can be queried in the same way. When I query for a known 20 records from the parent table, pulling in all the related records from the child tables, I get identical query costs across both, i.e. 50/50 cost for the batches. If this is true, then my giant project to change all of the tables like this appears to be pointless, other than speeding up inserts. Can anyone provide any light on the situation?

• Storing a SHA512 Password Hash in Database

  - by Chris

  In my ASP.NET web app I'm hashing my user passwords with SHA512. Despite much SO'ing and Googling I'm unclear how I should be storing them in the database (SQL2005) - the code below shows the basics of how I'm creating the hash as a string and I'm currently inserting it into the database into a Char(88) column as that seems to be the length created consistently Is holding it as a String the best way to do it, if so will it always be 88 chars on a SHA512 (as I have seen some bizarre stuff on Google)? Dim byteInput As Byte() = Encoding.UTF8.GetBytes(sSalt & sInput) Dim hash As HashAlgorithm = New SHA512Managed() Dim sInsertToDatabase As String = Convert.ToBase64String(hash.ComputeHash(byteInput))

• Converting plain text in SQL to hyperlink in Access

  - by manemawanna

  Hello, I've just started a new job my first since leaving University and as part of this my first task is to convert a wholly Access 2003 database to an Access front-end, SQL back-end. The Access database consists of a series of front end forms to add or review staff data, as part of this there is hyperlinks pointing to a photograph of the employee and there CV located on a shared drive. These were saved as hyperlinks within the Access DB. I have since converted the data in the Access DB to SQL and stored it in a database for me to test on, now as part of the data conversion the photo and CV locations were converted to nvarchar from hyperlink. I've done this using SSMA. My issue now is that I need to have these text links displayed and working as hyperlinks on the front end hidden behind the words "Photo" and "CV", but am unsure as to how to go about this, as in the past I've only ever used SQL and not Access. Any help or suggestions would be appreciated and if I've not been clear in any areas please feel free to ask questions and I'll try to clear anything up for you.

• Trigger Code on a table in my ERP Database

  - by David Stein

  My ERP Vendor has the following trigger on a table: SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO CREATE TRIGGER [dbo].[SOItem_DeleteCheck] ON [dbo].[soitem] FOR DELETE AS BEGIN DECLARE @RecCnt int, @LogInfo varchar(256) SET @RecCnt = (SELECT COUNT(*) FROM deleted) IF @RecCnt > 150 BEGIN RAISERROR (54010, 18, 1, 'SOItem') WITH LOG ROLLBACK TRANSACTION END SET @LogInfo = 'Deleting ' + LTRIM(STR(@RecCnt)) + ' Rows From SOItem' EXEC LogDeletes @LogInfo END GO This seems very inefficient to me. Doesn't select count(*) take longer than Count(specific field)?
