  • 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(); } }

  • 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.

  • Need help building SQL Query (simple JOIN)

    - by Newbie
    Hello! In my database, I have a "users", a "quests" and a "questings" table. A user can solve a quest. Solving a quest will save the "user_id" and the "quest_id" in my "questings" table. Now, I want to select all quests, a user has NOT solved (meaning there is no entry for this user and quest in "questings" table)! Let's say the user has the id 14. How to write this query? After solving this query, I want to filter the results, too. A quest and a user has a city, too. What to do for writing a query which returns all quests, a user has NOT solved yet, in the users city (user city == quest city)?

  • Looping over some selected values in a stored procedure

    - by macca1
    I'm trying to modify a stored procedure hooked into an ORM tool. I want to add a few more rows based on a loop of some distinct values in a column. Here's the current SP: SELECT GRP = STAT_CD, CODE = REASN_CD FROM dbo.STATUS_TABLE WITH (NOLOCK) Order by STAT_CD, SRT_ORDR For each distinct STAT_CD, I'd also like to insert a REASN_CD of "--" here in the SP. However I'd like to do it before the order by so I can give them negative sort orders so they come in at the top of the list. I'm getting tripped up on how to implement this. Does anyone know how to do this for each unique STAT_CD?

    I'm trying to rename the columns.

  • Use Linq to SQL to generate sales report

    - by Richard Reddy
    I currently have the following code to generate a sales report over the last 30 days. I'd like to know if it would be possible to use linq to generate this report in one step instead of the rather basic loop I have here. For my requirement, every day needs to return a value to me so if there are no sales for any day then a 0 is returned. Any of the Sum linq examples out there don't explain how it would be possible to include a where filter so I am confused on how to get the total amount per day, or a 0 if no sales, for the last days I pass through. Thanks for your help, Rich //setup date ranges to use DateTime startDate = DateTime.Now.AddDays(-29); DateTime endDate = DateTime.Now.AddDays(1); TimeSpan startTS = new TimeSpan(0, 0, 0); TimeSpan endTS = new TimeSpan(23, 59, 59); using (var dc = new DataContext()) { //get database sales from 29 days ago at midnight to the end of today var salesForDay = dc.Orders.Where(b => b.OrderDateTime > Convert.ToDateTime(startDate.Date + startTS) && b.OrderDateTime <= Convert.ToDateTime(endDate.Date + endTS)); //loop through each day and sum up the total orders, if none then set to 0 while (startDate != endDate) { decimal totalSales = 0m; DateTime startDay = startDate.Date + startTS; DateTime endDay = startDate.Date + endTS; foreach (var sale in salesForDay.Where(b => b.OrderDateTime > startDay && b.OrderDateTime <= endDay)) { totalSales += (decimal)sale.OrderPrice; } Response.Write("From Date: " + startDay + " - To Date: " + endDay + ". Sales: " + String.Format("{0:0.00}", totalSales) + "<br>"); //move to next day startDate = startDate.AddDays(1); } }

    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.

  • 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.

  • Eliminate duplicates in SQL query

    - by ewdef
    i have a table with 6 fields. the columns are ID, new_id price,title,Img,Active. I have datawhich is duplicated for the price column. When I do a select i want to show only distinct rows where new_id is not the same. e.g.- ID New_ID Price Title Img Active 1 1 20.00 PA-1 0X4... 1 2 1 10.00 PA-10 0X4... 1 3 3 20.00 PA-11 0X4... 1 4 4 30.00 PA-5 0X4... 1 5 9 20.00 PA-99A 0X4... 1 6 3 50.00 PA-55 0X4... 1 When the select statement runs, only rows with ID (1,4,9,6) should show. Reason being the new_ID with the higher price should show up. How can i do this?

  • 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?

  • Adding more OR searches with CONTAINS Brings Query to Crawl

    - by scolja
    I have a simple query that relies on two full-text indexed tables, but it runs extremely slow when I have the CONTAINS combined with any additional OR search. As seen in the execution plan, the two full text searches crush the performance. If I query with just 1 of the CONTAINS, or neither, the query is sub-second, but the moment you add OR into the mix the query becomes ill-fated. The two tables are nothing special, they're not overly wide (42 cols in one, 21 in the other; maybe 10 cols are FT indexed in each) or even contain very many records (36k recs in the biggest of the two). I was able to solve the performance by splitting the two CONTAINS searches into their own SELECT queries and then UNION the three together. Is this UNION workaround my only hope? Thanks. SELECT a.CollectionID FROM collections a INNER JOIN determinations b ON a.CollectionID = b.CollectionID WHERE a.CollrTeam_Text LIKE '%fa%' OR CONTAINS(a.*, '"*fa*"') OR CONTAINS(b.*, '"*fa*"') Execution Plan (guess I need more reputation before I can post the image):

  • How to use multiple identity numbers in one table?

    - by vincer
    I have an web application that creates printable forms, these forms have a unique number on them, the problem is I have 2 forms that separate numbers need to be created for them. ie) Form1- Numbered 2000000-2999999 Form2- Numbered 3000000-3999999 dbo.test2 - is my form information table Tsel - is my autoinc table for the 3000000 series numbers Tadv - is my autoinc table for the 2000000 series numbers What I have done is create 2 tables with just autoinc row (one for 2000000 series numbers and one for 3000000 series numbers), I then created a trigger to add a record to the coresponding table, read back the autoinc number and add it to my table that stores the form information including the just created autoinc number for the right series of forms. Although it does work, I'm concerned that the numbers will get messed up under load. I'm not sure the @@IDENTITY will always return the right value when many people are using the system. (I cannot have duplicates and I need to use the numbering form show above. See code below. ** TRIGGER ** CREATE TRIGGER MAKEANID2 ON dbo.test2 AFTER INSERT AS SET NOCOUNT ON declare @someid int declare @someid2 int declare @startfrom int declare @test1 varchar(10) select @someid=@@IDENTITY select @test1 = (Select name1 from test2 where sysid = @someid ) if @test1 = 'select' begin insert into Tsel Default values select @someid2 = @@IDENTITY end if @test1 = 'adv' begin insert into Tadv Default values select @someid2 = @@IDENTITY end update test2 set name2=(@someid2) where sysid = @someid SET NOCOUNT OFF

  • Grails: Duplicates & unique constraint validation

    - by rukoche
    OK here is stripped down version of what I have in my app Artist domain: class Artist { String name Date lastMined def artistService static transients = ['artistService'] static hasMany = [events: Event] static constraints = { name(unique: true) lastMined(nullable: true) } def mine() { artistService.mine(this) } } Event domain: class Event { String name String details String country String town String place String url String date static belongsTo = [Artist] static hasMany = [artists: Artist] static constraints = { name(unique: true) url(unique: true) } } ArtistService: class ArtistService { def results = [ [ name:"name", details:"details", country:"country", town:"town", place:"place", url:"url", date:"date" ] ] def mine(Artist artist) { results << results[0] // now we have a duplicate results.each { def event = new Event(it) if (event.validate()) { if (artist.events.find{ it.name == event.name }) { log.info "grrr! valid duplicate name: ${event.name}" } artist.addToEvents(event) } } artist.lastMined = new Date() if (artist.events) { artist.save(flush: true) } } } In theory event.validate() should return false and event will not be added to artist, but it doesn't.. which results in DB exception on artist.save() Although I noticed that if duplicate event is persisted first everything works as intended. Is it bug or feature? :P
