  • SQL LIKE question

    - by user176121
    I was wondering if there's a drawback (other than bad practice) to using something like this SELECT * FROM my_table WHERE id LIKE '1'; where id is an integer. I know you're supposed to use id=1 but I am writing a java program and if everything can use LIKE it'll be a lot easier for me. Also, so far, everything works fine; I get the correct query results, so if there is no drawback I will continue doing it like this. edit: I am using MySQL.

    - by Tony
    There's a field with type of varchar. It actually stores a float point string. Like 2.0 , 12.0 , 34.5 , 67.50 ... What I need is a update statement that remove the ending zeros of fields like 2.0 , 12.0 , change them to their integer representation , that is 2 , 12 ...,and leave 3.45 , 67.50 unchanged . How should I do this ? I am using oracle 10.

  • MongoDB equivalent of SQL "OR"

    - by Matt
    So, MongoDB defaults to "AND" when finding records. For example: db.users.find({age: {'$gte': 30}, {'$lte': 40}}); The above query finds users = 30 AND <= 40 years old. How would I find users <= 30 OR = 40 years old?

  • Trying to use table aliases in SQL...

    - by user366685
    I'm a graphic designer trying my best to understand table aliases, but it's not working. Here's what I have so far: SELECT colours.colourid AS colourid1, combinations.manufacturercolourid AS colourmanid1, colours.colourname AS colourname1, colours.colourhex AS colourhex1, combinations.qecolourid2 AS colouridqe2, colours.colourid AS colourid2, colours.colourname AS colourname2, colours.colourhex AS colourhex2, colours.colourid AS colourid3, combinations.qecolourid3 AS colouridqe3, colours.colourname AS colourname3, colours.colourhex AS colourhex3, colours.colourid AS colourid4, combinations.qecolourid4 AS colouridqe4, colours.colourname AS colourname4, colours.colourhex AS colourhex4, combinations.coloursupplierid FROM combinations INNER JOIN colours ON colours.colourid = combinations.manufacturercolourid; Now, the idea is that in the colours lookup table, the id will pull the colour code, hex and name from the lookup table so that I can pull the colour code, hex and name for the 4 colours that I'm looking for. I can get this to work, but it only pulls up the first name, code and hex and I'm just not seeing what I'm doing wrong.

  • 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 . . .

  • Setting custom SQL in django admin

    - by eugene y
    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?

  • 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(); } }

  • Oracle SQL outer join query puzzle

    - by user1651446
    So I am dumb and I have this: select whatever from bank_accs b1, bank_accs b2, table3 t3 where t3.bank_acc_id = t1.bank_acc_id and b2.bank_acc_number = b1.bank_acc_number and b2.currency_code(+) = t3.buy_currency and trunc(sysdate) between nvl(b2.start_date, trunc(sysdate)) and nvl(b2.end_date, trunc(sysdate)); My problem is with the date (actuality) check on b2. Now, I need to return a row for each t3xb1 (t3 = ~10 tables joined, of course), even if there are ONLY INVALID records (date-wise) in b2. How do I outer-join this bit properly? Can't use ANSI joins, must do in a single flat query. Thanks.

  • Efficiently select top row for each category in the set

    - by VladV
    I need to select a top row for each category from a known set (somewhat similar to this question). The problem is, how to make this query efficient on the large number of rows. For example, let's create a table that stores temperature recording in several places. CREATE TABLE #t ( placeId int, ts datetime, temp int, PRIMARY KEY (ts, placeId) ) -- insert some sample data SET NOCOUNT ON DECLARE @n int, @ts datetime SELECT @n = 1000, @ts = '2000-01-01' WHILE (@n>0) BEGIN INSERT INTO #t VALUES (@n % 10, @ts, @n % 37) IF (@n % 10 = 0) SET @ts = DATEADD(hour, 1, @ts) SET @n = @n - 1 END Now I need to get the latest recording for each of the places 1, 2, 3. This way is efficient, but doesn't scale well (and looks dirty). SELECT * FROM ( SELECT TOP 1 placeId, temp FROM #t WHERE placeId = 1 ORDER BY ts DESC ) t1 UNION ALL SELECT * FROM ( SELECT TOP 1 placeId, temp FROM #t WHERE placeId = 2 ORDER BY ts DESC ) t2 UNION ALL SELECT * FROM ( SELECT TOP 1 placeId, temp FROM #t WHERE placeId = 3 ORDER BY ts DESC ) t3 The following looks better but works much less efficiently (30% vs 70% according to the optimizer). SELECT placeId, ts, temp FROM ( SELECT placeId, ts, temp, ROW_NUMBER() OVER (PARTITION BY placeId ORDER BY ts DESC) rownum FROM #t WHERE placeId IN (1, 2, 3) ) t WHERE rownum = 1 The problem is, during the latter query execution plan a clustered index scan is performed on #t and 300 rows are retrieved, sorted, numbered, and then filtered, leaving only 3 rows. For the former query three times one row is fetched. Is there a way to perform the query efficiently without lots of unions?

  • Creating a stored procedure in SQL Server 2008 that will do a "facebook search"

    - by dig
    Hello, I'm trying to implement a facebook search in my system (auto suggest while typing). I've managed to code all the ajax stuff, but I'm not sure how to query the database. I've created a table called People which contains the fields: ID, FirstName, LastName, MiddleName, Email. I've also created a FTS-index on all those fields. I want to create a stored procedure that will get as a parameter the text inserted in the query box and returns the suggestions. For example, When I will write in the textbox the query "Joh Do" It will translate to the query: select * from People where contains(*, '"Joh*"') and contains(*, '"Do*"') Is there a way to do that in stored procedure? P.S I've tried to use the syntax select * from People where contains(*,'"Joh*" and "Do*"') but it didn't returned the expected results, probably because it needs to search the words on different fields. Is there a way to fix that? Thanks.

  • Application self aware of external database record modifications.

    - by Khou
    How do you make your application aware that a database record was changed or created by an external application rather than the application itself? Do you add a special check sum to the database record or what do you do to stop external changes to the database? (in case it was hacked and the hacker decides to add a new record or change an existing database record)
