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.
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
[Code] ......
Can anyone recommend a good reference book on views, stored procedures (system stored
procedures as well) and triggers? I am in need of assistance in these areas.
Thanks!

guys, ive never worked with Views before so forgive me.
i know how to create one, and that it creates a virtual table in memory, but i've got one small question.
if i create a view:
CREATE view dbo.myView
as
select Distinct FirstName,LastName from SomeTable
When ever i reference that view, such as
Select FirstName,LastName
from myView
where LastName like 'Jo%'
does that View Refresh itself??
in other words does it run each time i Reference it??? or is it static from when i created it.
Wouldnt it be easier just to use a #TempTable or some other Table thats used to hold a few values?
thanks for any help

Is there anybody familiar with indexed view here?
Can I add a foriegn key on a indexed view to reference other table?

Hi everybody.
I created an application role in a database (DB1) and gave it all the rights on a view in DB1 which refers to a table located in another db (DB2). I also gave the rights to the app role on a table of DB1
I tried to use this app. role through the sp_setapprole launched by a user (server principal?) which is SQL Server administrator (and local administrator (Win 2003 Server)).
With the following query
SELECT USER_NAME()
I see that the approle is being used.
Than, if I query the table on DB1 everything works, but if I query the view, referring a table in db2 I get following error:
The server principal "NameOfServerPrincipal" is not able to access the database "DB2" under the current security context.
What should I do to make it work?
The table in DB2 has the same schema of the view in DB1 which refers to it.
I put the DB1 TrustWorthy and both the database have the db_chaining option activated.
Any idea on how to solve the problem would be widely appreciated.
Thank you very much.

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.

Hi,
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,

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.

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 am using vs 2010 to write my dtsx import scripts.I use a script component as a source to create a flat file destination file.Everything have been working fine,but then my development machine crashed and we have to install everything again.Now when i use the execute package utility to test my scripts i get the following error:
Error system.NullReferenceException: Object refrence not set to an instance reference.
In PreExecute section

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?)
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

I have a SQL table that consists of columns A, B and C. I am trying to construct a view consisting of all columns (i.e. A, B, C) and a computed column. This computed column has the following logic:
If B is blank or null then NewColumn = A + ' - ' C
else
NewColumn = A + ' - ' + B

Is there a way of changing the value of a column in a view? For example, I have a table with defect code and a description (other columns as well). In a view, I would like to see only the defect code and the description, but if the code is > 90, I would like to define what the description is.

I have a view that has 2 columns. The first column is associated with a function for the Units. The second column calculates the Market Value:
View
====
Col1: Unit = get_number_of_units()
Col2: MV = get_number_of_units() * get_unit_value()
I need to call get_number_of_units() twice in the view. Is it possible to changes Col2 to something like: MV = Col1 * get_unit_value()?
Is get_unit_value() being called if I do Select Col1 from View?
Thanks.

I'm using SQL Server 2008 to solve the following exercise.
I have three Tables:
Table CUSTOMER with columns: CustomerID,Company,ContactName,Phone
Table ORDER with columns: OrderID,OrderDate,ShippedDate,ShipperID,Freight,CustomerID
Table Shipper with columns:ShipperID,Company,Phone
I need to Create a view listing the shipper and the number of unshipped orders. I have been trying to use joins or possibly subqueries, but I'm not getting a correct result for a ShipperID with NO unshipped orders.My view should looks like: ShipperID, Company, Phone, UnshippedOrders
Not sure if I am approaching this correctly. I can get name, address, zip code from a table via a VIEW. But the problem is I need to create another column called "status" in the same view that is based on "customer_end_date" if end_date> GETDATE() then 'P'(pick-up) and end_date< GETDATE () then 'I'(install). Using a stored procedure this is easy...but how would I do this in a VIEW?

View 2 Replies View RelatedHello all,
I'd like to create a view which shows all specific column values

as calculated values from another column,
if for example i have the table:

| 123 | null |
| 126 | 9 |

i would like the view to be:
---------------
| col1 | col2 |

I don't really know how to do that, although i'm quite sure it's possible, any help will be appreciated,

Hi,I have a view that looks something like this -CREATE VIEW myview AS SELECTmyudf(col1) as col1, col2, col3FROM mytableThe view has an 'INSTEAD OF' trigger on it to do the correct thing oninsert. When I run the bcp, it runs successfully, but the valueinserted into col1 is always NULL. I modified my trigger to get abetter idea of what was happening, and when I look at the values ofINSERTED.col1, they are all null. It appears that bcp is setting thecolumn value to null, presumable because the view definintion for thiscolumn is a derived column.Does any one know a way around this?Thanks!

I have a view that shows payment amount, payment date. I need to add a column to the view that shows what fiscal year the payment belongs to.
How can this be done?
I do have a table that has the fiscal start and end in it, tblGlobal with fields FiscalYearStart and FiscalYearEnd.
