hello,
in the script task component - i need to refer to Row.Column9.ToString() but the Column9 is coming from a variable. meaning - at run time it can be Column9 or Column7 at other runs. how can i write Row.ColumnName.ToString() in a dynamic way? (aka that the ColumnName is dynamic and not hard coded?)
thanks!

Hi Craig/Kamal,
I got your email address from your web cast. I really enjoyed the web cast and found it to be
very informative.
Our company is planning to use SSIS (VS 2005 / SQL Server 2005). I have a quick question
regarding the product. I have looked for the information on the web, but was not able to find
relevant information.
We are getting Source data from two of our client in the form of Excel Sheet. These Excel sheets
Are generated using reporting services. On examining the excel sheet, I found out that the name
Of the columns contain data itself, so the names are not static such as Jan 2007 Sales, Feb 2007 Sales etc etc.
And even the number of columns are not static. It depends upon the range of date selected by the user.
I wanted to know, if there is a way to import Excel sheet using Integration Services by defining the position
Of column, instead of column name and I am not sure if there is a way for me to import excel with dynamic
Number of columns.
Your help in this respect is highly appreciated!
Thanks,
Hi Anthony, I am glad the Web cast was helpful.
Kamal and I have both moved on to other teams in MSFT and I am a little rusty in that area, though in general dynamic numbers of columns in any format is always tricky. I am just assuming its not feasible for you to try and get the source for SSIS a little closer to home, e.g. rather than using Excel output from Reporting Services, use the same/some form of the query/data source that RS is using.
I suggest you post a question on the SSIS forum on MSDN and you should get some good answers.

how can i reference a column in a view.
My duplicate check runs against the entire column. There might be another test field that has the same value, and that might be valid, so im trying to make sure that when i do the check, i am checking only against the serial number field and not all test fields.
Hi,I have a DataGrid whose DataSource is an SQLDataSource. This SQLDataSource references a SQL Server table with an Identity column, named Id. The SQLDataSource has generated an Update statement for me, but this only works if the Id column is selected for display in the DataGrid, and has Visible = True. If not, then the @original_Id parameter to the generated Update statement has a value of Nothing, and the Update has no effect. So is there a way to enable the Update statement to work, without the user having to see the Id column in the DataGrid? Many thanks,Keith.

I am writing the following querry.
Code Snippet
Select dbo.fn_EnGiftId(116) AS 'EnGiftId', dbo.fn_DeGiftId(''+ EnGiftId +'') AS 'DeGiftId'
But the above querry giving me the following error When i am executing the querry:
Code Snippet
Server: Msg 207, Level 16, State 3, Line 1
Invalid column name 'EnGiftId'.
The scenario is I have created two functions 1st is for encryption of GiftId and 2nd is for Decryption of the Encrypted Giftid.
But in the same select querry i want to use the name of column which i have given to the encrypted data in the selct querry i want to use that same column name in the decryption function uin the same querry.
When i am executing the below querry it gives me the required output. So Why not above querry.
Code Snippet
Select dbo.fn_EnGiftId(116) AS 'EnGiftId', dbo.fn_DeGiftId(''+ dbo.fn_EnGiftId(116) +'') AS 'DeGiftId'
i d't want to write the encryption function again and again. Is theer any way to avoid this.?????
I create a matrix,
Row groups: Province
Column groups: Project Type
Values: Count of # of Projects, Sum of Amount ($)
What this displays is the following. How do I go about calculating what's highlighted in yellow? It is Amount of OneProjectType / Amount of TwoProject Type.
I have two tables shown below and I wish to add a calculated column to Table 1.
Table1 Table2
ID Activity Activity 1 Activity 2 Activity 3 etc etc etc Total
1 Activity 1 values values values Total value
2 Activity 2 values values values Total value
3 Activity 3 values values values Total value
etc
I want each row in the new column to show the corresponding activity divided by the sum of the total. So in the row with Activity 3 I want the formula SUM(Table2[Activity 3])/SUM(Table2[Total]). Also the number of activities will vary.
I am actually wanting to calculate a more complicated formula which calculates the correlation .
How can I list the stored procedures and user-defined functions that reference a given column? I could search ROUTINE_DEFINITION in INFORMATION_SCHEMA.ROUTINES for '%MyColumnName%' but MyColumnName is not always unique.
Thanks.
Hi there,
I am a new member of this site and I am not very much aware of T-sql's working.
My question is what if I need to get one column's data to be the heading of another column.
To be very exact I have a school's database. The table I am talking about is of the results of students. The table contains Student ID, Subject ID, Total marks of the subject, Marks obtained in the subject. Now I want to print a report by generating data from this table. Right now the data is something like this
StuID - - - SubID - - - -Tot - - -Obt
1 - - - - - - -1 - - - - - - -50 - - - 38
1 - - - - - - -2 - - - - - - -50 - - - 41
1 - - - - - - -3 - - - - - - -50 - - - 42
1 - - - - - - -4 - - - - - - -50 - - - 40
2 - - - - - - -1 - - - - - - -50 - - - 35
2 - - - - - - -2 - - - - - - -50 - - - 40
2 - - - - - - -3 - - - - - - -50 - - - 42
2 - - - - - - -4 - - - - - - -50 - - - 41
StudentID and SubjectID fields are related to other tables so I can get the names from there but when I need the report I need the data in the form of
StuID - Sub 1 - - - Sub 2 - - - Sub 3 - - - -Sub4
1 - - - - 38 - - - - - - 41 - - - - - - 42 - - - - - - 40
2 - - - - 35 - - - - - - 40 - - - - - - 42 - - - - - - 41
The Subjects can be different for different students so the query should be dynamic instead of hard coding the names of the subjects. I hope I am clear with my question. The subjectIDs or their names will become the headings and they will contain the obtained marks for that subjects in their columns just for the reports. I have also checked the PIVOT function but was not able to do what I wanted.
Thanks.
Just encountered something that I wasn't expected, in that a user who has an explicit deny on a column in a table was able to select it when referenced through a view in a schema they have the SELECT permission on. This seems to me to go against the principle that DENY overrides everything when it comes to permissions? Is this how it's meant to work?
Code is below:-
--create test user
CREATE USER TestDenyOnViewUser WITHOUT LOGIN
GO
--create test schema (authorization dbo - same owner as dbo schema so ownership chaining will apply)
CREATE SCHEMA TestDenyOnView AUTHORIZATION dbo

Hi,
On my aspx Web page, I want to delete a member from database table 'tblMember', but if this MemberID is used as FK in another table, I want to display a user friendlier message like "You cannot delete this member, ....." I am using Try, Catch blocks in my Web Page.
Currently it display this message:
"DELETE statement conflicted with COLUMN REFERENCE constraint 'FK_..._....' The conflict occurred in database '...', table 'tblMembers', column 'MemberID'. The statement has been terminated. "
So how should I precisely trap this error? Does anybody know what Exception is it? or what error number in SQL server?
Thanks

I have a requirement of table partitioning. we have 10 years of data on a table which is 30 billion up rows on 2005 server we are upgrading it to 2014. we have to keep 7 years of data. there is no keys on table or date column. since its a huge amount of data and many users its slow down the process speed. we are thinking to do partition on 7 years for Quarterly based. but as i said there is no date column on table we have to use reference table to get date. is there a way i can do the partitioning with out adding date column on table? also does partition will make query faster?
I have think three ways to do it.
1. leave as it is.
2. 7 years partition on one server
3. 3 years partition on server1 and 4 years partition on server2 (for 4 years is snapshot better?)
Hello,I'm still extremely novice to SQL and I've tried googling how to produce this result but I've been encountering a lot dynamic sql commands which isn't exactly what I want. If this is an ignorant question I do apologize but heres my scenario: I have a table with columns of the day, for instance: Monday_hasData (bit)Monday_DataAnd what I want to do is essentially pass in "Monday" as a parameter and rather than doing an If statement on each row, I would like to just like to do something like assign @dayCheck + "_hasData" to a variable and then use @dayCheck as part of my query. Is this possible or am I going to have to have 7 cases? Thank you for any input,Chance

Hi everyone,
So I have to export from a SQL 2005 table to a dBaseIV table using SSIS. Easy enough, however the catch is that the tables being exported will vary. I can send variables to the the package calling the sql table name and creating the DBF file with the same columns on the fly.
The problem is mapping the columns. From what I've been reading there is no way to alter the mapping in a package at runtime. I was hoping that there would be some sort of auto mapping setting that would match on the field names but I guess not. Anybody run in to this issue and have a work around? Thanks in advance....

Got my first real job to do in SSIS and it's not really much fun. Here goes. I have excel files from various vendors, none of which are in the same format. Now I'm less concerned with the names, I have those in variables so that's not a big deal. My issue is around the column names. Let's say we have file a, b and c. In file a the first name field is called [first name], in file b it's first_name and in file c it's firstname. What I want to do is create 1 package that can handle these files regardless of how first name is spelled. I was thinking I could open the file and somehow search for a column name that contained the word "first%" and then map the column name to a variable. I'm sort of stuck though on how to actually do that. Help. And please don't tell me to tell the vendors to standardize. That's the end goal but it's like herding cats.

Hi guys 'n gals,
I am trying to achieve something a bit complex (or at least appears to be for me).
I have the following table structure:
UID, GroupID, ColumnName, ColumnValue
here is some example data:
UID, GroupId, ColumnName, ColumnValue
1, 1, MAC Address, 8a7sd87sad
2, 1, IP Address, 192.168.1.100
3, 1, Name, John
4, 2, MAC Address, 09a8sd098as
5, 2, Name, Steven
and here is what I would like the example to come out like:
GroupID, MAC Address, IP Address, Name
1, 8a7sd87sad, 192.168.1.100, John
2, 09a8sd098as, NULL, Steven
It needs to be completely dynamic though, as a new column name could be entered to the source table at any time...
I have tried Dynamic SQL and JOINs, but can only seem to get it to work correctly. I was starting to consider doing a loop similar to this:
Code Snippet
DECLARE @ColumnName varchar(128)
DECLARE @Sql varchar(255)
SELECT @ColumnName = [ColumnName] FROM tblSourceData
SELECT @Sql = 'SELECT [GroupId], [ColumnValue] AS ['+@ColumnName+'] FROM tblSourceData'
EXEC (@Sql)
Could somebody please point me in the right direction? I've heard a bit about Pivot tables in my search for this solution, is that perhaps the route I need to go?
Regards,
Justin

Hi,
I have to choose a particular column from a table whenever a condition met. That means i have to use the column in the select query whenever the condition met otherwise i have to create a dummy column with the same column name.
I tried to use the following sample query.
Eg:
Create table temp
(test_id int,
test varchar(100))
Declare @var varchar(100)
Set @Var='Hi'
Select
case when @Var='HI' then "None" else Test_new End as Test
from Temp
But it throw error as "Invalid column 'Test_new' "
As per my situation the Test_new column will be available in temp table whenever the condition is not met.So when @var<>'HI' i have to get the details of the test_new column otherwise i have to create a dummy column with the same name.
Example, suppose you have these 2 tables(NOTE: My example is totally different, but I'm simply trying to setupthe a simpler version, so excuse the bad design; not the point here)CarsSold {CarsSoldID int (primary key)MonthID intDealershipID intNumberCarsSold int}Dealership {DealershipID int, (primary key)SalesTax decimal}so you may have many delearships selling cars the same month, and youwanted a report to sum up totals of all dealerships per month.select cs.MonthID,sum(cs.NumberCarsSold) as 'TotalCarsSoldInMonth',sum(cs.NumberCarsSold) * d.SalesTax as 'TotalRevenue'from CarsSold csjoin Dealership d on d.DealershipID = cs.DealershipIDgroup by cs.MonthIDMy question is, is there a way to achieve something like this:select cs.MonthID,sum(cs.NumberCarsSold) as 'TotalCarsSoldInMonth',TotalCarsSoldInMonth * d.SalesTax as 'TotalRevenue'from CarsSold csjoin Dealership d on d.DealershipID = cs.DealershipIDgroup by cs.MonthIDNotice the only difference is the 3rd column in the select. Myparticular query is performing some crazy math and the only way I knowof how to get it to work is to copy and past the logic which isgetting out way out of hand...Thanks,Dave

How can I make this stored procedure concept work:
-----------------------------------------------
Create Procedure MyProc @MyValue varchar(5)
As
Declare @ColumnName as varchar(11)
Set @ColumnName = 'Price_' + @MyValue
Select Sum(Price) As @ColumnName --????
From MyTable where Item = @MyValue
Return
-----------------------------------------------
Using @MyValue = 23 should make the Sum(Price) column name 'Price_23'. It's not working. What am I doing wrong?

I am unfortunately lumered with a table I cannot edit that stores a division 2 characters along with boolean fields '0506', '0607', '0708' ... (academic years) to represent if that particular division is active in the current academic year. This has made me have to resort to dynamic sql within a stored procedure to input the appropriate field names.
Is there a better way to do it, it's not mission critical to make it not use dynamic sql but I would prefer not to.
I want to write a query that will give me a dynamic amount of columns back.What I want to do, I want to create a calendar application, in which foreach employee, I want to show if he is in the office or not.this should look like:ID, Name, 1,2,3,4,5,6,7,888,Leo,0,0,1,1,1,0,0,1The amount of columns is dynamic, and is a period of time, with a column foreach day.Any suggestions what the best approach to this could be?ThanksLeo
View 3 Replies View RelatedIll start off by saying that I am an ASP.NET developer and I am self-taught in using SSRS2005. (quite poorly I might add) That being said I am having a problem with a report im building. This report has 10-12 different metrics I am reporting on and I have each of them displayed in their own matrix. The first matrix was created by the report wizard that launches when you add a new report.
To give you an overview of how I am setting up these reports I will describe the structure I am using on nearly all of the matrices. I am reporting on classes that are managed by my company and held at 3rd party locations. My matrix has the 3rd party location in the rows and the quarter the class was held is the column. Matrix setup looks like this:
________|_______Quarter____________
|MetricA|MetricB|MetricC|etc...
LocationA|
LocationB|
LocationC|
The problem Im having is this. All matrices that weren't created by the wizard don't grow dynamically. Say I have 2 quarters of data I am reporting on, Instead of having a column for quarter1 and quarter 2, the report generates separate matrices for each quarter. This is true for each matrix that I created using a matrix control from the toolbox. The matrix that was created by the wizard however, has dynamic columns that grow to the right as expected.
I am populating my datasets using Stored Procedures and the matrix that behaves normally uses a different dataset than the 4 others I have completed thus far which share a dataset.
I have looked everywhere I can think of for a checkbox or a property I need to adjust and I cant find one. Anyone have any ideas??
