  • Linq-to-SQL: How to perform a count on a sub-select

    - by Peter Bridger
    I'm still trying to get my head round how to use LINQ-to-SQL correctly, rather than just writing my own sprocs. In the code belong a userId is passed into the method, then LINQ uses this to get all rows from the GroupTable tables matching the userId. The primary key of the GroupUser table is GroupUserId, which is a foreign key in the Group table. /// <summary> /// Return summary details about the groups a user belongs to /// </summary> /// <param name="userId"></param> /// <returns></returns> public List<Group> GroupsForUser(int userId) { DataAccess.KINv2DataContext db = new DataAccess.KINv2DataContext(); List<Group> groups = new List<Group>(); groups = (from g in db.Groups join gu in db.GroupUsers on g.GroupId equals gu.GroupId where g.Active == true && gu.UserId == userId select new Group { Name = g.Name, CreatedOn = g.CreatedOn }).ToList<Group>(); return groups; } } This works fine, but I'd also like to return the total number of Users who are in a group and also the total number of Contacts that fall under ownership of the group. Pseudo code ahoy! /// <summary> /// Return summary details about the groups a user belongs to /// </summary> /// <param name="userId"></param> /// <returns></returns> public List<Group> GroupsForUser(int userId) { DataAccess.KINv2DataContext db = new DataAccess.KINv2DataContext(); List<Group> groups = new List<Group>(); groups = (from g in db.Groups join gu in db.GroupUsers on g.GroupId equals gu.GroupId where g.Active == true && gu.UserId == userId select new Group { Name = g.Name, CreatedOn = g.CreatedOn, // ### This is the SQL I would write to get the data I want ### MemberCount = ( SELECT COUNT(*) FROM GroupUser AS GU WHERE GU.GroupId = g.GroupId ), ContactCount = ( SELECT COUNT(*) FROM Contact AS C WHERE C.OwnerGroupId = g.GroupId ) // ### End of extra code ### }).ToList<Group>(); return groups; } }

  • MS-Access to SQL Server 2000 problem with datetime

    - by 0plus1
    I'm trying to transfer some data from Access to SQL Server 2000 (there are no other way to do this sadly), I'm using Access to mssql to do the job. The program fails everytime it finds a datetime in this fashion: 03/07/2009 10.17.00 While it imports date like this: 29/12/2008 I don't understand where this problem come from so I ask you for your help. Thank you very much.

  • Why would you use "AS" when aliasing a SQL table?

    - by froadie
    I just came across a SQL statement that uses AS to alias tables, like this: SELECT all, my, stuff FROM someTableName AS a INNER JOIN someOtherTableName AS b ON a.id = b.id What I'm used to seeing is: SELECT all, my, stuff FROM someTableName a INNER JOIN someOtherTableName b ON a.id = b.id I'm assuming there's no difference and it's just syntactic sugar, but which of these is more prevalent/wide-spread? Is there any reason to prefer one over the other?

  • SQL Random number not working

    - by JMSA
    declare @fieldForceCounter as int declare @SaleDate as dateTime declare @RandomNoSeed as decimal set @fieldForceCounter = 1 set @SaleDate = '1 Jan 2009' set @RandomNoSeed = 0.0 WHILE @fieldForceCounter <= 3 BEGIN while @SaleDate <= '1 Dec 2009' begin INSERT INTO MonthlySales(FFCode, SaleDate, SaleValue) VALUES(@fieldForceCounter, @SaleDate, RAND(@RandomNoSeed)) set @saleDate = @saleDate + 1 set @RandomNoSeed = Rand(@RandomNoSeed) + 1 end set @SaleDate = '1 Jan 2009' set @fieldForceCounter = @fieldForceCounter + 1 END GO This T-SQL command was supposed to insert random values in the 'SaleValue'-column in the 'MonthlySales'-table. But it is inserting '1' every time . What can be the problem?

  • Convert a MSSQL database to MYSQL database

    - by soldieraman
    Alright so I want to convert an already exist MSSQL database (2005) to a MYSQL database. There is nothing extraordinary to be done The only things I need to achieve is Recreate the tables Transfer data Relationships would be nice but not necessary No views, no sprocs, no functions. Any easy way to do this. Also do you know of any DST (Database Synchronization Tool) which would let me do MSSQL to MYSQL MYSQL to MYSQL MSSQL to MSSQL (I know there is SQL Delta for this)

  • T-SQL String Functions: difference between using Left/Right and Substring and strange behaviour

    - by TheObserver
    I am using SQL Server 2008 & 2005 (Express). I'm trying to extract part of an alpha numeric string from a varchar field. RIGHT(str_field,3) yields null values but substring(str_field, len(str_field)-2, len(str_field)) gives the right value. left(str_field,7) gives the expected values. What gives? I would have thought that RIGHT(str_field,3) and substring(str_field, len(str_field)-2, len(str_field)) are equivalent expressions.

  • Command line or library "compare tables" utility for SQL server with comprehensive diff output to a

    - by MicMit
    I can't find anything like that. Commercial or free ( XSQL Lite is suitable for my case and ) tools show diffs in grids with possibility to export to CSV. Also they generate sync SQL scripts when run from command line. What I need is an output as a comprehensive report ( XML , HTML ) suitable for parsing so that I would be able to show similar diff grid in my application ( updated old/new values for each column , added - all values for row , deleted - all values for row and etc... ) .

  • Microsoft SQL Count problem

    - by Matt
    Hey smarties. I'm having trouble with the following SQL statement. I know that I can't do a GROUP BY on the OnlineStatus column, and it makes sense because it's a function call, not an actual column in my table. How would I modify this so that I can get a count of how many users are online? SELECT CASE dbo.fnGetWebUserOnlineStatus(W.Id) WHEN 1 THEN 'Online' WHEN 2 THEN 'Ingame' ELSE 'Offline' END AS OnlineStatus FROM dbo.WebUsers W WHERE W.[Status]=1 GROUP BY OnlineStatus

  • Is there an equivalent of "OPTION(RECOMPILE)" or "WITH RECOMPILE" for an entire connection?

    - by kamens
    I'm curious. Is there any way to prevent SQL query execution plans from being cached for an entire connection's duration? Can I run a command that basically says, "use OPTION(RECOMPILE) for all subsequent commands until I tell you to stop doing so?" I'm acutely aware of all the performance trade-offs here, and I know this is not a step to be taken lightly. However, I'm in a unique situation where this behavior may be advantageous.

  • Performance in SQL Mobile with one big column that's not being selected

    - by Anthony Mastrean
    I have a SQL Mobile database with one table. It has several columns with useful, often queried data and one column that stores a relatively large string per record (1000+ characters) that is not queried often. Imagine this fake schema, the "lifeStory" field is the large one. table1 String firstName String lastName String address String lifeStory A representative query would be SELECT firstName, lastName, address FROM table1 WHERE firstName = :p1 Does anyone know of any performance concerns leaving that large, infrequently queried column in this table?

How is it possible in MS SQL Server 2005?
