  • T-SQL 2005 - Divide by zero error encountered

    - by Grant
    Hi, I am trying to get some percentage data from a stored procedure using code similar to the line below. Obviously this is going to cause a (Divide by zero error encountered) problem when base.[XXX_DataSetB] returns 0 which may happen some of the time. Does anyone know how i can deal with this in the most efficient manner? Note: There would be about 20+ lines looking like the one below... cast((base.[XXX_DataSetB] - base.[XXX_DataSetA]) as decimal) / base.[XXX_DataSetB] as [XXX_Percentage]

  • SQL SERVER Spatial Data

    - by Sam
    Hi All, I am struggeling finding an effectient way to find a distance between a Point that interetcts a polygon and the border of that polygon. I was able to use the STDistance comparing the point to every point that made up the polygon but that is taking a lot of time. Using SPatial indexed wasnt much helpful because the STDistance is not part of any constraint and even when I did put the constraint, the index didnt help much. I appreciate any feedback. Thanks.

  • An aggregate may not appear in the WHERE clause unless it is in a subquery contained in a HAVING cla

  • Comparing date range quarters sql server

    - by CR41G14
    I have a policies in a system PolRef Start End POL123 22/11/2012 23/12/2014 POL212 24/09/2012 23/10/2012 POL214 23/08/2012 29/09/2012 I am asking a user for a reporting date, the user enters 24/10/2012 this becomes @StartDate From this I derive what the quarter is by the month: set @currentMonth = Month(@StartDate) if @currentMonth = 1 or @currentMonth = 2 or @currentMonth = 3 begin set @startmonth = 1 set @endmonth = 3 end if @currentMonth = 4 or @currentMonth = 5 or @currentMonth = 6 begin set @startmonth = 4 set @endmonth = 6 end if @currentMonth = 7 or @currentMonth = 8 or @currentMonth = 9 begin set @startmonth = 7 set @endmonth = 9 end if @currentMonth = 10 or @currentMonth = 11 or @currentMonth = 12 begin set @startmonth = 10 set @endmonth = 12 end I then get a date range: @quarterStartDate = CAST(CAST(YEAR(@StartDate) AS varchar) + '-' + CAST(@startMonth AS varchar) + '-' + '01') AS Date) @quarterEndDate = CAST(CAST(YEAR(@EcdDate) AS varchar) + '-' + CAST(@endMonth AS varchar) + '-' + '31') AS Date) This will give me 01-10-2012 and 31-12-2012. Basically I need a script to only bring back the policies that are in this quarter. The policy doesn't have to span the entire quarter date range, just exist in the quarter date range. The results expected would be PolRef Start End POL123 22/11/2012 23/12/2014 POL212 24/09/2012 23/10/2012 Pol123 appears because it spans over the quarterly date range. Pol212 is there because it expires in that quarter date range. Pol214 does not appear because it neither spans, expires or starts in this quarter. Any help would be greatly appreciated

  • Dynamically changing databases in SQL Server 2000

    - by spuppett
    At work we have a number of databases that we need to do the same operations on. I would like to write 1 SP that would loop over operations and set the database at the beginning of the loop (example to follow). I've tried sp_executesql('USE ' + @db_id) but that only sets the DB for the scope of that stored procedure. I don't really want to loop with hard coded database names because we need to do similar things in many different places and it's tough to remember where things need to change if we add another DB. Any thoughts Example: DECLARE zdb_loop CURSOR FAST_FORWARD FOR SELECT distinct db_id from DBS order by db_id OPEN zdb_loop FETCH NEXT FROM zdb_loop INTO @db_id WHILE @@FETCH_STATUS = 0 BEGIN USE @db_id --Do stuff against 3 or 4 different DBs FETCH NEXT FROM zdb_loop INTO @db_id END CLOSE zdb_loop DEALLOCATE zdb_loop

  • Next Identity Key LINQ + SQL Server

    - by user569347
    To represent our course tree structure in our Linq Dataclasses we have 2 columns that could potentially be the same as the PK. My problem is that if I want to Insert a new record and populate 2 other columns with the PK that was generated there is no way I can get the next identity and stop conflict with other administrators who might be doing the same insert at the same time. Case: A Leaf node has right_id and left_id = itself (prereq_id) **dbo.pre_req:** prereq_id left_id right_id op_id course_id is_head is_coreq is_enforced parent_course_id and I basically want to do this: pre_req rec = new pre_req { left_id = prereq_id, right_id = prereq_id, op_id = 3, course_id = query.course_id, is_head = true, is_coreq = false, parent_course_id = curCourse.course_id }; db.courses.InsertOnSubmit(rec); try { db.SubmitChanges(); } Any way to solve my dilemma? Thanks!

  • Sql Server Development Server and Live

    - by Chris
    I have a database project that goes through iterations (only one so far) and I need to deploy a testing version to a live server. I'm not sure how to go about this. I can make all the changes in a copy and then remake those changes in the live version. That doesn't make sense. Is there a way to change a server name to an existing server? What's the best practice for this scenario?

  • SQL Select Upcoming Birthdays

    - by Crob
    I'm trying to write a stored procedure to select employees who have birthdays that are upcoming. SELECT * FROM Employees WHERE Birthday > @Today AND Birthday < @Today + @NumDays This will not work because the birth year is part of Birthday, so if my birthday was '09-18-1983' that will not fall between '09-18-2008' and '09-25-2008'. Is there a way to ignore the year portion of date fields and just compare month/days? This will be run every monday morning to alert managers of birthdays upcoming, so it possibly will span new years. Here is the working solution that I ended up creating, thanks Kogus. SELECT * FROM Employees WHERE Cast(DATEDIFF(dd, birthdt, getDate()) / 365.25 as int) - Cast(DATEDIFF(dd, birthdt, futureDate) / 365.25 as int) <> 0

  • What scenarios/settings will result in a query on SQL Server (2008) return stale data

    - by s1mm0t
    Most applications rarely need to display 100% accurate data. For example if this stack overflow question displays that there have been 0 views, when there have really been 10, it doesn't really matter. This is one way that the (perceived) performance of applications can be improved, by caching results and therefore sometimes not showing 100% accurate results. There are some cases where the data does need to be 100% accurate though. So if I run the query select * from Foo I want to be sure that the results are not stale. Now depending on how my database is set up, other activity on the database, use of transactions and isolation levels etc this query may or may not be a true reflection of the world. What scenario's and settings can people think of that will result in this query returning stale results or given that another connection is part way through a transaction that has updated this table, how can I guarantee that when the above query returns, the results will be accurate.

  • Basic SQL Query, I am newbie

    - by user3530547
    I just started my database and query class on Monday. We met on Monday and just went over the syllabus, and on Wednesday the network at school was down so we couldn't even do the power point lecture. Right now I am working on my first homework assignment and I am almost finished but I am having trouble on one question. Here is is... Write a SELECT statement that returns one column from the Customers table named FullName that joins the LastName and FirstName columns. Format the columns with the last name, a comma, a space, and the first name like this: Doe, John Sort the result set by last name in ascending sequence. Return only the contacts whose last name begins with letters from M to Z. Here is what I have so far... USE md0577283 SELECT FirstName,LastName FROM Customers ORDER BY LastName,FirstName My question is how do I format is Lastname, FirstName like the professor wants and how do I only select names M-Z? If someone could point me in the right direction I would greatly appreciate it. Thank you. PS With all do respect, I didn't ask for the answer I asked for a nudge in the right direction so why the down vote guys?

  • Creating a SQL lookup

    - by Scott
    I’m in the process of cleaning up a database table. Due to the way some of the data needed to be processed, now I need to go back and perform a “reverse lookup” on the data. For example, a field for one of the records is set to “car” and I need to set that record’s tranportmode field to “1” (for “car”). The lookup tables are already created. I just need to do the reverse lookup part. The cleansed tables will only have the numeric lookup value.
