Hi All ...
WITH myCTE (x,y,z) AS (SELECT x,y,z, from myTable)
SELECT x,y,sum(z) from myCTE
SELECT y,z,sum(x) from myCTE
the second SELECT fails, and says invalid object name. does the CTE go out of scope after i reference it once?
never mind the semantics of what I am SELECTing, I just want to be able to reference the CTE more than once in my SP
am I trying to use the CTE in a way that was not intended?
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
TextReader = new system.io.streamreader(" file name")
In the CreateNewOutputRows:
dim nextLine as string
nextLine = textReader.ReadLine
[code]...
is there something which i did not install or what can be the error?
Hi y'all
Does anybody know reference or pdf file or free e-learning on the web?
DECLARE Loan_cursor CURSOR FOR
SELECT Loan_No,store
FROM loan
WHERE maturity_date > '2001-04-30' and loan_no like 'ABL%'
OPEN Loan_cursor
-- Perform the first fetch.
FETCH NEXT FROM Loan_cursor
-- Check @@FETCH_STATUS to see if there are any more rows to fetch.
WHILE @@FETCH_STATUS = 0
BEGIN
Declare @LoanNo varchar(12)
** Set @LoanNo = Loan_No
-- This is executed as long as the previous fetch succeeds.
FETCH NEXT FROM Loan_cursor
END
CLOSE Loan_cursor
DEALLOCATE Loan_cursor
when l run the cursor l get the error
Server: Msg 207, Level 16, State 3, Line 15
Invalid column name 'Loan_No'.
.
If l reference it as Set @LoanNo = LoanTable.Loan_No l get the error
Server: Msg 107, Level 16, State 3, Line 15
The column prefix 'loan' does not match with a table name or alias name used in the query.
All l'm trying to do is to compare the loan number that l get from the cursor to the value in the loans table. Maybe reference is a better word

Hi,
I'm looking for a good reference guide online as I am more used to mysql (and stil quite limited vocab at that)
I create table outside of a database by accident and I'm now looking for the sql syntaxt for moving tables, but I can't find it anywhere?
most simple guides don't seem to provide the syntax to do this. :(
does any one know any good pages to get some sql commands
and explainations thanks
Hi,
I am access SQL 7 via ADO in some ASP pages. My database objects were created under a user name aliased to the dbo. As a result, when I have my client logon to make a connection, I have to preface all my object references with the name of the owner, i.e., Select * from mydboname.people . Is there a way to avoid having to prefix all my transact sql statements with the owner?
thanks,
steve
I have two tables that are reference to each other by foreign key, now I would like to alter the table so the it doesn't reference each other any more. What is the syntax to alter a table so that the fk field doesn't reference a table anymore. Thanks in advance for the help.

As I posted earlier, I am relatively new to TSQL. I have been given a few books:
O'Reilly SQL on SQL Server 2005
O'Reilly SQL in a Nutshell
Mastering SQL Server 2005 - Sybex
Beginning SQL Server 2005 Programming - Wrox
I have a copy of SQL2005 Developers Edition on a development server. So I think I have some decent tools at my disposal.
I was wondering if there are any other sites or forums that might be suggested for learning SQL programming? Right now, I am just making stuff up and following examples in books, etc. I would like to find a site where there are beginner level projects for no other purpose than educational. Something where I can get more hands on of the design and programming aspects. Just to practice.
Thanks,

i have this code,
CREATE TABLE s

name VARCHAR(16),

)
CREATE TABLE p
(pno VARCHAR(5) NOT NULL PRIMARY KEY,
descr VARCHAR(16),
color VARCHAR(8)
)
CREATE TABLE sp
(sno VARCHAR(5) NOT NULL REFERENCES s,
pno VARCHAR(5) NOT NULL REFERENCES p,
qty INT CHECK (qty>=0),
PRIMARY KEY (sno, pno)
)
when i run this query i get an error saying:
Column 's.sno' is not the same length as referencing column 'sp.sno' in foreign key 'FK__sp__sno__5EBF139D'. Columns participating in a foreign key relationship must be defined with the same length.
can anyone assist me what to be done?

Hello. I'm getting an error - "Object reference not set to an instance of an object" when running an SSRS report with graphs. It only happens when the returned dataset is empty (based on parameters set by the user, it is possible to return no rows). I've tried using the NoRows property (I entered "No Data" in the property box), but I still get the same error. Is there another way to account for an empty dataset in charts?
Thanks,

Hello everyone !
Given a UDT, is there any way to get a reference to the table where the specific instance is running ?
IE: Let's suppose we have defined a UDT named UDTPoint; now we define two tables: ATable & BTable, wich both have one column that is defined as UDTPoint.
When an insert/update/delete operation on ATable or BTable occurs, the UDTPoint class needs to verify in which context it is running (ATable or BTable) before doing operations on data.
Is there any way to achieve that ?
Thanks

Hi,
I wanted to add a reference to an assembly in my report (not a DLL, but an EXE). As I see there is no option to select an assembly which is an EXE. Firstly, is it possible to add a reference to an EXE (I guess not)? Secondly, If no, why is it not possible?

Hi,
Our tables have a reference field which users can enter their own references into.
However, they can choose to have the system calculate the next reference number.
The reference can contain any characters from a-z, A-Z and 0-9.
In our system, reference AAAA is greater than reference ZZZ; the next reference after AAAA is AAAB.
How would I calculate the greatest current reference in the table?

The table above is my users table. It allows for a user to be at multiple sites or multiple locations within a single site or multiple sites. Would it be wise to use a auto incrementing primary key instead of the 3 column composite key? The reason I ask is because if I am referencing this SU table (which I will be a lot), a lot more data would be replicated to the tables which have the foreign key to this table, right? But if I used a single incrementing column as the primary key, only a small integer would be used as the foreign key, saving space?Does this make sense?
View 1 Replies View RelatedI have a .NET assembly that I need to reference and use within my SSIS script task.
The only way I can acheive this is to strongly name my assembly and put it in the GAC.
This is not possible as my assembly is already in production and uses other 3rd party assemblies that would also need to be registered in the GAC.
As a workaround, I have created a .Net console application that references my assembly, that call from a SSIS Process Task.
Does anyone know of another way I could use my .NET assembly within my SSIS package?
Any help appreciated.

I had a 2003 project designed by someone else. I upgraded it to 2005 using the conversion wizard.
Now it all works find within vs2005, I deploy it to a location else where on my pc and create a virtaul directory and map it so that I'm using IIS. This all works fine.
As soon as I move it to a virtual machine (windows 2k server SP4 IIS5) I get object reference not set to an instance, basically what I can determine is my sqlconnection fails when it is opened. Can anyone tell me?

See previous errors. Could anyone please let me know how to create reference for composite key. Thanks in advance,Arun.
