• Copy Rows in a One to Many with LINQ to SQL

  - by Refracted Paladin

  I have a table that stores a bunch of diagnosis for a single plan. When the users create a new plan I need to copy over all existing diagnosis's as well. I had thought to try the below but this is obviously not correct. I am guessing that I will need to loop through my oldDiagnosis part, but how? Thanks! My Attempt so far... public static void CopyPlanDiagnosis(int newPlanID, int oldPlanID) { using (var context = McpDataContext.Create()) { var oldDiagnosis = from planDiagnosi in context.tblPlanDiagnosis where planDiagnosi.PlanID == oldPlanID select planDiagnosi; var newDiagnosis = new tblPlanDiagnosi { PlanID = newPlanID, DiagnosisCueID = oldDiagnosis.DiagnosisCueID, DiagnosisOther = oldDiagnosis.DiagnosisOther, AdditionalInfo = oldDiagnosis.AdditionalInfo, rowguid = Guid.NewGuid() }; context.tblPlanDiagnosis.InsertOnSubmit(newDiagnosis); context.SubmitChanges(); } }

• Get substring between "\" where multiple "\"

  - by AceAlfred

  Found this solution to get substring after slash () character DECLARE @st1 varchar(10) SET @st1 = 'MYTEST\aftercompare' SELECT @st1 ,SUBSTRING(@st1, CHARINDEX('\', @st1) + 1, LEN(@st1)) http://social.msdn.microsoft.com/Forums/sqlserver/en-US/5c3a5e2c-54fc-43dd-b12c-1a1f6784d7d8/tsql-get-substring-after-slash-character But is there a way to get substring after second slash or even more? DECLARE @st1 varchar(50) --Added more slashes SET @st1 = 'MYTEST\aftercompare\slash2\slash3\slash4' SELECT @st1 --This part would need some work --,SUBSTRING(@st1, CHARINDEX('\', @st1) + 1, LEN(@st1)) And getting only the substring between the slashes. Values: [1] "aftercompare" - [2] "slash2" - [3] "slash3" - [4] "slash4"

  - by durilai

  I have a table that has millions of records and we are looking at implementing table partitioning. Looking at it we have a foreign key "GroupID" that we would like to partition on. Is this possible? The Group will have more entries added to it, so as new GroupID's are added can the partition's be made dynamically?

• SQL return error within PHP

  - by Luke

  I use GET to get the id of a result. $id = $_GET['id']; I then use the following code: <? $q = $database->friendlyDetails($id); while( $row=mysql_fetch_assoc($q) ) { $hu = $row['home_user']; $ht = $row['home_team']; $hs = $row['home_score']; $au = $row['away_user']; $at = $row['away_team']; $as = $row['away_score']; $game = $row['game']; $name = $row['name']; $match = $row['match_report1']; $compid = $row['compid']; $date = $row['date_submitted']; $sub = $row['user_submitted']; } ?> And friendDetails- function friendlyDetails($i) { $q = "SELECT * FROM ".TBL_SUB_RESULTS." INNER JOIN ".TBL_FRIENDLY." ON ".TBL_FRIENDLY.".id = ".TBL_SUB_RESULTS.".compid WHERE ".TBL_SUB_RESULTS.".id = '$i'"; return mysql_query($q, $this->connection); } For some reason, the code will only return what is under id =1. Can anyone see anything obvious I am doing wrong?

• Database normalization and duplicate values

  - by bretddog

  Consider a Parent / Child / GrandChild structure in a database table schema, or even a deeper hierarchy. These being in the same aggregate. One table DAYS keeps a single row per day, and has a "Date" field. This is the root table, or maybe a child of the root. No row can ever be deleted in this table. In this case, however complex my table schema looks like, however far away in the hierarchy any other table is, is there any reason why any other table would hold a Date value? Can't it instead just have a FK to the DAYS table. I obviously assume that the creation of these date fields happen not before such datefield exist in the DAYS table. I'm now thinking just about the date part to be relevant, not the time part. Not sure if all databases can store these individually. That's maybe relevant, but not really the focus of the question.

• Figuring out the resource a lock in SQL Server 2000 affects

  - by Michael Lang

  I am adding a simple web-interface to show data from a commercial off the shelf (COTS) application. This COTS issues locks on any record the user is actively looking at (whether they intend to edit and update it or not). I have found sp_lock and the Microsoft sp_lock2 scripts and can see the locks, so that's all well and good. However, I cannot figure out how I can tell if a specific record I am about to update has been affected by one of these locks. If I submit the update request and there is in fact a lock, the web-interface will wait indefinitely until the user closes the window in the COTS. How can I either: a) determine before issuing an update that the record has been locked OR b) issue an update that will immediately return with a LOCKED status rather than indefinitely waiting on the COTS user to close their window on that record?

• Linq to SQL - design question.

  - by UshaP

  HI, Currently i have one big datacontex with 35 tables (i dragged all my DB tables to the designer). I must admit it is very comfortable cause i have ORM to my full DB and query with linq is easy and simple. My questions are: 1. Would you consider it bad design to have one datacontext with 35 tables or should i split it to logic units? 2. Is there any performance penalties for using such a big datacontext? Thanks, Pini.

• Is there a way to split the results of a select query into two equal halfs?

  - by Matthias

  I'd like to have a query returning two ResultSets each of which holding exactly half of all records matching a certain criteria. I tried using TOP 50 PERCENT in conjunction with an Order By but if the number of records in the table is odd, one record will show up in both resultsets. Example: I've got a simple table with TheID (PK) and TheValue fields (varchar(10)) and 5 records. Skip the where clause for now. SELECT TOP 50 PERCENT * FROM TheTable ORDER BY TheID asc results in the selected id's 1,2,3 SELECT TOP 50 PERCENT * FROM TheTable ORDER BY TheID desc results in the selected id's 3,4,5 3 is a dup. In real life of course the queries are fairly complicated with a ton of where clauses and subqueries.

• 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 . . .

• Asynchronous SQL Operations

  - by Paul Hatcherian

  I've got a problem I'm not sure how best to solve. I have an application which updates a database in response to ad hoc requests. One request in particular is quite common. The request is an update that by itself is quite simple, but has some complex preconditions. For this request the business layer first requests a set of data from the data layer. The business logic layer evaluated the data from the database and parameters from the request, from this the action to be performed is determined, and the request's response message(s) are created. The business layer now executes the actual update command that is the purpose of the request. This last step is the problem, this command is dependent on the state of the database, which might have changed since the business logic ran. Locking down the data read in this operation across several round-trips to the database doesn't seem like a good idea either. Is there a 'best-practice' way to accomplish something like this? Thanks!

• how can i substitute a NULL value for a 0 in an SQL Query result

  - by Name.IsNullOrEmpty

  SELECT EmployeeMaster.EmpNo, Sum(LeaveApplications.LeaveDaysTaken) AS LeaveDays FROM EmployeeMaster FULL OUTER JOIN LeaveApplications ON EmployeeMaster.id = LeaveApplications.EmployeeRecordID INNER JOIN LeaveMaster ON EmployeeMaster.id = LeaveMaster.EmpRecordID GRoup BY EmployeeMaster.EmpNo order by LeaveDays Desc with the above query, if an employee has no leave application record in table LeaveApplications, then their Sum(LeaveApplications.LeaveDaysTaken) AS LeaveDays column returns NULL. What i would like to do is place a value of 0 (Zero) instead of NULL. I want to do this because i have a calculated column in the same query whose formular depends on the LeaveDays returned and when LeaveDays is NULL, the formular some how fails. Is there away i can put 0 for NULL such that that i can get my desired result.

• using NEWSEQUENTIALID() with UPDATE Trigger

  - by Ram

  I am adding a new GUID/Uniqueidentifier column to my table. ALTER TABLE table_name ADD VersionNumber UNIQUEIDENTIFIER UNIQUE NOT NULL DEFAULT NEWSEQUENTIALID() GO And when ever a record is updated in the table, I would want to update this column "VersionNumber". So I create a new trigger CREATE TRIGGER [DBO].[TR_TABLE_NAMWE] ON [DBO].[TABLE_NAME] AFTER UPDATE AS BEGIN UPDATE TABLE_NAME SET VERSIONNUMBER=NEWSEQUENTIALID() FROM TABLE_NAME D JOIN INSERTED I ON D.ID=I.ID/* some ID which is used to join*/ END GO But just realized that NEWSEQUENTIALID() can only be used with CREATE TABLE or ALTER TABLE. I got this error The newsequentialid() built-in function can only be used in a DEFAULT expression for a column of type 'uniqueidentifier' in a CREATE TABLE or ALTER TABLE statement. It cannot be combined with other operators to form a complex scalar expression. Is there a workaround for this ? Edit1: Changing NEWSEQUENTIALID() to NEWID() in the trigger solves this, but I am indexing this column and using NEWID() would be sub-optimal

• Use a SELECT to Print a Bunch of INSERT INTOs

  - by Mikecancook

  I have a bunch of records I want to move to another database and I just want to create a bunch of inserts that I can copy and paste. I've seen someone do this before but I can't figure it out. I'm not getting the escapes right. It's something like this where 'Code', 'Description' and 'Absent' are the columns I want from the table. SELECT 'INSERT INTO AttendanceCodes (Code, Description, Absent) VALUES (' + Code + ',' + Description + ',' + Absent')' FROM AttendanceCodes The end result should be a slew of INSERTS with the correct values like this: INSERT INTO AttendanceCodes (Code, Description, Absent) VALUES ('A','Unverified Absence','UA')

• Connecting to an MS SQL Server from Silverlight?

  Normally, I would use a PHP webservice to do this, but since the front-end is hosted on a linux box, I need another way to do this (so I don't have to go through the trouble of installing FreeTDS, etc. I will if I have to). Is there a better way to do this? I'm not a web guy, but I'm trying my best.

• Setting custom SQL in django admin

  I'm trying to set up a proxy model in django admin. It will represent a subset of the original model. The code from models.py: class MyManager(models.Manager): def get_query_set(self): return super(MyManager, self).get_query_set().filter(some_column='value') class MyModel(OrigModel): objects = MyManager() class Meta: proxy = True Now instead of filter() I need to use a complex SELECT statement with JOINS. What's the proper way to inject it wholly to the custom manager?
