  • SQl rows to columns conversion

    - by Thihara
    Hi, I have a table ClassAttendance and I'm using MSSQL 2005 studentID--attendanceDate---------------------------------------status 1004--------2010-03-17--------------------------------------------------0 1005--------2010-03-17--------------------------------------------------1 1006--------2010-03-17--------------------------------------------------0 1007--------2010-03-17--------------------------------------------------0 1004--------2010-03-19--------------------------------------------------0 1005--------2010-03-19--------------------------------------------------1 1006--------2010-03-19--------------------------------------------------0 1007--------2010-03-19--------------------------------------------------0 1004--------2010-03-20--------------------------------------------------1 as you can see studentID is a foreign Key for a table called StudentData and attendedDate has an unknown number of rows. Can i get the output like below by using a query? I need the dates in one month to be columns and the value of the date columns will be values in the status column. The number of date records per studentID is the same its the number of dates in the attendanceDate filed that is unknown. studentID---------2010-03-17--------2010-03-19------2010-03-20 1004-----------------------------0----------------------0--------------------1 etc. This is for a creating a report so I need to do it in a query. Please help if you can.

  • code optimization; switch versus if's

    - by KaiserJohaan
    Hello, I have a question about whether to use 'case' or 'ifs' in a function that gets called quite alot. Here's the following as it is now, in 'ifs'; the code is self-explanatory: int identifyMsg(char* textbuff) { if (!strcmp(textbuff,"text")) { return 1; } if (!strcmp(textbuff,"name")) { return 2; } if (!strcmp(textbuff,"list")) { return 3; } if (!strcmp(textbuff,"remv")) { return 4; } if (!strcmp(textbuff,"ipad")) { return 5; } if (!strcmp(textbuff,"iprm")) { return 6; } return 0; } My question is: Would a switch perform better? I know if using ifs, I can place the most likely options at the top.

  • SQL 2005: Select top N, group by ID with joins

    - by Suzy Fresh
    I'm having real difficulty with a query involving 3 tables. I need to get the 3 newest users per department grouped by department names. The groups should be sorted by the users.dateadded so the department with the newest activity is first. The users can exist in multiple departments so Im using a lookup table that just contains the userID and deptID. My tables are as follows. Department - depID|name Users - userID|name|dateadded DepUsers - depID|userID The output I need would be Receiving John Doe - 4/23/2010 Bill Smith - 4/22/2010 Accounting Steve Jones - 4/22/2010 John Doe - 4/21/2010 Auditing Steve Jones - 4/21/2010 Bill Smith - 4/21/2010

  • How to transform vertical table into horizontal table?

    - by avivo
    Hello, I have one table Person: Id Name 1 Person1 2 Person2 3 Person3 And I have its child table Profile: Id PersonId FieldName Value 1 1 Firstname Alex 2 1 Lastname Balmer 3 1 Email [email protected] 4 1 Phone +1 2 30004000 And I want to get data from these two tables in one row like this: Id Name Firstname Lastname Email Phone 1 Person1 Alex Balmer [email protected] +1 2 30004000 What is the most optimized query to get these vertical (key, value) values in one row like this? Now I have a problem that I done four joins of child table to parent table because I need to get these four fields. Some optimization is for sure possible. I would like to be able to modify this query in easy way when I add new field (key,value). What is the best way to do this? To create some StoreProcedure? I would like to have strongly types in my DB layer (C#) and using LINQ (when programming) so it means when I add some new Key, Value pair in Profile table I would like to do minimal modifications in DB and C# if possible. Actually I am trying to get some best practices in this case.

  • SQL Server 2008 - Keyword search using table Join

    - by Aaron Wagner
    Ok, I created a Stored Procedure that, among other things, is searching 5 columns for a particular keyword. To accomplish this, I have the keywords parameter being split out by a function and returned as a table. Then I do a Left Join on that table, using a LIKE constraint. So, I had this working beautifully, and then all of the sudden it stops working. Now it is returning every row, instead of just the rows it needs. The other caveat, is that if the keyword parameter is empty, it should ignore it. Given what's below, is there A) a glaring mistake, or B) a more efficient way to approach this? Here is what I have currently: ALTER PROCEDURE [dbo].[usp_getOppsPaged] @startRowIndex int, @maximumRows int, @city varchar(100) = NULL, @state char(2) = NULL, @zip varchar(10) = NULL, @classification varchar(15) = NULL, @startDateMin date = NULL, @startDateMax date = NULL, @endDateMin date = NULL, @endDateMax date = NULL, @keywords varchar(400) = NULL AS BEGIN SET NOCOUNT ON; ;WITH Results_CTE AS ( SELECT opportunities.*, organizations.*, departments.dept_name, departments.dept_address, departments.dept_building_name, departments.dept_suite_num, departments.dept_city, departments.dept_state, departments.dept_zip, departments.dept_international_address, departments.dept_phone, departments.dept_website, departments.dept_gen_list, ROW_NUMBER() OVER (ORDER BY opp_id) AS RowNum FROM opportunities JOIN departments ON opportunities.dept_id = departments.dept_id JOIN organizations ON departments.org_id=organizations.org_id LEFT JOIN Split(',',@keywords) AS kw ON (title LIKE '%'+kw.s+'%' OR [description] LIKE '%'+kw.s+'%' OR tasks LIKE '%'+kw.s+'%' OR requirements LIKE '%'+kw.s+'%' OR comments LIKE '%'+kw.s+'%') WHERE ( (@city IS NOT NULL AND (city LIKE '%'+@city+'%' OR dept_city LIKE '%'+@city+'%' OR org_city LIKE '%'+@city+'%')) OR (@state IS NOT NULL AND ([state] = @state OR dept_state = @state OR org_state = @state)) OR (@zip IS NOT NULL AND (zip = @zip OR dept_zip = @zip OR org_zip = @zip)) OR (@classification IS NOT NULL AND (classification LIKE '%'+@classification+'%')) OR ((@startDateMin IS NOT NULL AND @startDateMax IS NOT NULL) AND ([start_date] BETWEEN @startDateMin AND @startDateMax)) OR ((@endDateMin IS NOT NULL AND @endDateMax IS NOT NULL) AND ([end_date] BETWEEN @endDateMin AND @endDateMax)) OR ( (@city IS NULL AND @state IS NULL AND @zip IS NULL AND @classification IS NULL AND @startDateMin IS NULL AND @startDateMax IS NULL AND @endDateMin IS NULL AND @endDateMin IS NULL) ) ) ) SELECT * FROM Results_CTE WHERE RowNum >= @startRowIndex AND RowNum < @startRowIndex + @maximumRows; END

  • SSIS - Skip Missing Files

    - by Greg
    I have a SSIS 2008 package that calls about 10 other SSIS packages (legacy issues, don't ask). Each of those child packages loads a specific file into a table. But sometimes one or more of these input files will be missing. How can I let a child package fail (because a file is missing) but let the rest of the parent package keep on running? I've tried increasing the maximum error count on the parent package, the tasks in the parent package that call each child, and in the child package itself. None of that seemed to make any difference. I still get this error when I run it with a file missing: SSIS Warning Code DTS_W_MAXIMUMERRORCOUNTREACHED. The Execution method succeeded, but the number of errors raised (2) reached the maximum allowed (1); resulting in failure. This occurs when the number of errors reaches the number specified in MaximumErrorCount. Change the MaximumErrorCount or fix the errors. Edit: failpackageonfailure and faulparentonfailure are already all set to false everywhere.

  • SQL Query Help Part 2 - Add filter to joined tables and get max value from filter

    - by Seth
    I asked this question on SO. However, I wish to extend it further. I would like to find the max value of the 'Reading' column only where the 'state' is of value 'XX' for example. So if I join the two tables, how do I get the row with max(Reading) value from the result set. Eg. SELECT s.*, g1.* FROM Schools AS s JOIN Grades AS g1 ON g1.id_schools = s.id WHERE s.state = 'SA' // how do I get row with max(Reading) column from this result set The table details are: Table1 = Schools Columns: id(PK), state(nvchar(100)), schoolname Table2 = Grades Columns: id(PK), id_schools(FK), Year, Reading, Writing...

  • net c# lock statement in data access layer

    - by Pedro Rivera
    I saw a code where they have the data access layer like this: public class CustomerDA{ private static readonly object _sync = new object(); private static readonly CustomerDA _mutex = new CustomerDA(); private CustomerDA(){ } public CustomerDA GetInstance(){ lock(_sync){ return _mutex; } } public DataSet GetCustomers(){ //database SELECT //return a DataSet } public int UpdateCustomer(some parameters){ //update some user } } public class CustomerBO{ public DataSet GetCustomers(){ //some bussiness logic return CustomerDA.GetInstance().GetCustomers(); } } I was using it, but start thinking... "and what if had to build a facebook like application where there are hundreds of thousands of concurrent users? would I be blocking each user from doing his things until the previous user ends his database stuff? and for the Update method, is it useful to LOCK THREADS in the app when database engines already manage concurrency at database server level?" Then I started to think about moving the lock to the GetCustomers and UpdateCustomer methods, but think again: "is it useful at all?"

    Why are UNIQUE Constraints needed in database ? Can you provide any examples ? Primary Key is UNIQUE by default... Understandable as they are referred in other tables as Foreign keys... relation is needed to connect them for rdbms platform... but why would one refer to other columns as UNIQUE, what is benefit of doing so ?)

  • sql query --need some suggestions

    - by benjamin button
    I have a table with list of cycle codes.CYCLE_DEFINITION. each and every cycle_code has 12 months entries in another table(PM1_CYCLE_STATE). Each and every month has a cycle_start_date and a cycle_close_date. i will check with a particular date(lets say sysdate) and check what is the current month of every cycle.additionally i will also get the list of future 3 more months of that particular cycle. the query i have written is as below: SELECT cycd,cm,sd,ed,ld FROM (SELECT pcs.cycle_code CYCD,LTRIM(pcs.cycle_month,'0')+0 CM, pcs.cycle_start_date SD,pcs.cycle_close_date ED,ld.logical_date LD FROM pm1_cycle_state pcs,logical_date ld WHERE ld.logical_date BETWEEN pcs.cycle_start_date AND pcs.cycle_close_date and ld.logical_date_type='B') UNION SELECT cycd,cm,sd,ed,ld FROM (SELECT pcs.cycle_code CYCD,DECODE(LTRIM(pcs.cycle_month,'0')+1,13,1,14,2,15,3,LTRIM(pcs.cycle_month,'0')+1) CM ,pcs.cycle_start_date SD,pcs.cycle_close_date ED,ld.logical_date LD FROM pm1_cycle_state pcs,logical_date ld WHERE ld.logical_date BETWEEN pcs.cycle_start_date AND pcs.cycle_close_date and ld.logical_date_type='B') UNION SELECT cycd,cm,sd,ed,ld FROM (SELECT pcs.cycle_code CYCD,DECODE(LTRIM(pcs.cycle_month,'0')+2,13,1,14,2,15,3,LTRIM(pcs.cycle_month,'0')+2) CM ,pcs.cycle_start_date SD,pcs.cycle_close_date ED,ld.logical_date LD FROM pm1_cycle_state pcs,logical_date ld WHERE ld.logical_date BETWEEN pcs.cycle_start_date AND pcs.cycle_close_date and ld.logical_date_type='B') UNION SELECT cycd,cm,sd,ed,ld FROM (SELECT pcs.cycle_code CYCD,DECODE(LTRIM(pcs.cycle_month,'0')+3,13,1,14,2,15,3,LTRIM(pcs.cycle_month,'0')+3) CM ,pcs.cycle_start_date SD,pcs.cycle_close_date ED,ld.logical_date LD FROM pm1_cycle_state pcs,logical_date ld WHERE ld.logical_date BETWEEN pcs.cycle_start_date AND pcs.cycle_close_date and ld.logical_date_type='B') This query is running perfectly fine. This will result in all the cycle_codes with exactly 4 rows for current month and future 3 months. Now the requirement is if any of the month is missing.how could i show it? for eg: the output of the above query is cycd cm 102 1 102 10 102 11 102 12 103 1 103 10 103 11 103 12 104 1 104 10 104 11 104 12 Now lets say the row with cycd=104 and cm=11 is not present in the table,then the above query will not get the row 104 11. I want to display only those rows. how could i do it?
