| Indexes on a Query with a pivot function Posted: 24 Apr 2013 06:32 PM PDT Hi all,Many thanks to the poster that helped me clear up a misconception that I was having with indexes a week ago but now I have a question as to whether indexes are possible to create on a pivoted view. Say we have two tables:People:PeopleIdFirstNameLastNameAgeAddressCountryProfession.... some other fields .....Employee:EmployeeIdEmQualifier - this is the string name for the column fieldEmData - this is the data valueand in order to access data from the Employee table we have a pivoted view, call it Employee_Pivot_View:Select EmployeeId, LastName, FirstName, Department, Company, EmploymentStatusFrom(Select EmployeeId, EmQualifier, EmData From Employee) as EPIVOT(MAX(EmData) For EmQualifier IN (LastName, FirstName, Department, Company, EmploymentStatus)) As E_PivotIf I were to write a query:SELECT P.FirstName, P.LastName, P.Age, P.Address, EPV.Company, EPV.DepartmentFROM People P INNER JOIN Employee_Pivot_View EPV ON (P.LastName = EPV.LastName AND P.FirstName = EPV.FirstName)Where EPV.EmploymentStatus = 'Employed'I know that I can't use an indexed view on a PIVOT but is it possible to generate an index on the Employee table, in order to improve performance? Please ignore the percentage of hits the WHERE condition can generate, let's say it's under 5 % so that an index seek can be used. |

| Error converting varchar to numeric only in where clause Posted: 24 Apr 2013 12:10 AM PDT Hi experts...I have a problem with one of my SQL Server query's...First of all, we are in SQL Server 2008 R2 Enterprise Edition (64-bit), version 10.50.4000.0 on a server with OS : Microsoft Windows NT 6.0 (6002)I have a table with following columns:DataId intPathId intValue varchar(4000)The column 'Value' can contain all kind of data, from string to int to decimal to dates...But, depending on the PathId, it always has the same type of data.For example, for PathId's 30 and 31, the Value column contains always an amount --> numeric dataFollowing query runs without any problem, returning almost 30.000 records :SELECT DataId, PathId, , CONVERT(numeric(14,2),Value) as AmountFROM dbo.TestTableWHERE PathId IN (30,31)Following query proves to me that all records do have numeric data in the table :SELECT DataId, PathId, , ISNUMERIC(Value) as Test_Value_Numeric, CONVERT(numeric(14,2),Value) as Amount, ISNUMERIC(CONVERT(numeric(14,2),Value)) as Test_Amount_NumericFROM dbo.TestTableWHERE PathId IN (30,31)Both columns Test_Value_Numeric and Test_Amount_Numeric always return 1.Now, when I try to leave out the records which have an amount = 0, my query returns me an error : 'Msg 8114, Level 16, State 5, Line 1; Error converting data type varchar to numeric.'Just add following line to the query to see what's happening : "AND CONVERT(numeric(14,2),Value) > 0"(or use a CTE to create a dataset with amount, and then in your result-query, retrieve data from the cte where amount > 0, same issue)To test, I used the last query which works, and did a "select into" to a 2nd testTable, and the column 'Amount' was created as numeric(14,2) in the new testTable.I really hope someone can point out my issue, I am searching for it now for hours, have tried 3 experts, but nobody can give an explanation.Is this a bug ???PS : I have attached in an Excel the real data, so you can test it yourself with my data... |

The above sample code will give you an idea about what i need. My table contains an identity column and a foreign key. I will get a foreign key as a source id and this id may have multiple records in the table. I take this source records (in above case records in ##Temp1) in a temporary table and i have to compare this source records with other records in original table (in above case records in ##Temp2). In the sample I gave, mentioned the result I am expecting.The first record in result is generated because source table have 'name4' with date and which is not available in target table for id 2.The second record in result is generated because target table have 'name5' and which is not available in source table.The third record in result is generated because source table have 'name4' and which is not available in target table for id 3.The fourth record in result is generated because source table have 'name1' with date '2010-01-02' and which is mismatched with record in source table.Could you help me to create a script for generating this output? Please give me an idea. Right now I have is a very complex script contains left join which will not give the exact result. |
| How to update order status based on detail information Posted: 24 Apr 2013 02:52 PM PDT I have 2 tables ( orderheader and ordershipmentdetail). The order can be closed when all products and their requested quantities are received.A product in a specific order can be shipped partially( for example, the customer orders 10 bulbs, first shipment sends out 6 bulbs, the second shipment 4 bulbs totally the requested quantity of 10).This is sample data where the expected result is to set status=20 on headerid=4 because all its shipments are fulfilled. The other headers will have status=10. Can you suggest how I can find the set of headerids that have all requested shipments fulfilled?Thank you!-- status 10 means open-- status 20 means closedcreate table #header( headerid int, status int) -- status 1 means Requested-- status 2 means Received create table #details (detailid int, headerid int, product int, QuantityRequested int, QuantityReceived int, status int) insert into #header values (1,null), (2,null), (3,null), (4,null) insert into #details values (10, 1, 1000, 100,50,2), (11, 1, 1000, 100,25,2), (12, 1, 1100, 8,8,2), (13, 2, 5000, 100,25,2), (14, 2, 5000, 100,75,2), (15, 3, 6000, 12,null,1), (16, 4, 7000, 12,6,2), (17, 4, 7000, 12,6,2), (18, 4, 8000, 15,5,2), (19, 4, 8000, 15,5,2), (20, 4, 8000, 15,5,2), (21, 4, 9000, 3,3,2) select * from #header select * from #details select headerid, QuantityRequested, sum(QuantityReceived) as QuantityReceived ,product, status from #details d group by headerid,QuantityRequested, product, status drop table #details drop table #header |

| Implicit Conversions in fulltext indexing? Posted: 24 Apr 2013 10:21 AM PDT I periodically run Jonathan Kehayias' script to find implicit conversions in the plan cache for the SQL server that supports our line of business databases. I'm usually able to find these in code and get the data types lined up so that implicit conversions don't have to occur.However, there's multiple instances where an implicit conversion appears to occur when a table which has a full text index is updated. That particular table has an int-type primary key on the account number, yet the full text index is processing it as a bigint data type as far as I can tell. One of the expressions in our plan cache shows the following:Scalar Operator(CASE WHEN CASE WHEN [Expr1068] IS NOT NULL THEN (1) ELSE (4) END=(4) THEN CONVERT_IMPLICIT(bigint,[S**********].[dbo].[tblMainAcc********].[AccountKey],0) ELSE [S******].[sys].[fulltext_index_docidstatus_415508384].[docid] END)If anybody has any ideas on what might cause this, I'd very much appreciate the feedback. It's as much a matter of intellectual curiosity as anything else right now.Sincerely,Andre RanieriPS: Here's Jonathan's implicit conversion query code:/****************************************************************************** Presentation: Performance Tuning with the Plan Cache * FileName: 3.2 - Implicit Column Side Conversions.sql** Summary: Demonstrates how to find column side implicit conversions and the * statements that generated it by parsing XML Plans stored in the * plan cache.** Date: October 16, 2010 ** SQL Server Versions:* 2005, 2008, 2008 R2* ******************************************************************************* Copyright (C) 2010 Jonathan M.

But if I select the path manually in the file name field then it allows to take backup without any error.So why does it happen? I want this user to take backup without these error messages.(But i can't give sysadmin for the user).How can I solve it?(I already some article stating that use sql query and sqlcmd to take backup.but i want it to work using SSMS itself) [url=http://social.msdn.microsoft.com/Forums/en-US/sqltools/thread/a0ada2bb-f66e-4af1-a1d7-3057bd5a7c53]Also see my detailed discussion on this problem in msdn forum by me here[/url] |
