SQL Servers Place In The 'Application'
Jan 28, 2004
I'm rapidly understanding that much more of my application as a whole is in SQL Server that I would have originally thought.
Stored Procedures
Triggers
Constrains
And so on
It generally means that some of the stuff I'd have naturally done in the Business Layer might be best done in SQL - certain issues in the Business Layer might be best being triggers or constraints for example...
One thing that still puzzles me, and I'd like some references or advice now as it's a blank area in my mind is how this interfaces to your asp.net code.
Obviously I call stored procedures and the like from code, and use parameters, etc, not problem, it's more what I do when these stored procedures or associated triggers fail (or a constrain fails - though this should be less likely)?
SQL sends back an error? But what? Then what do you get your page to do, especially if SQL failed midway through a 'big' transaction? Do you have save 'where the user was somehow' so they don't start inputting again?
It's all a bit vague at the moment, some detail would be nice? :)

Hi, What I want to do is simple to explain, hard to obtain (i guess): I want to fill a dropdownlist with the names of the sqlservers detected on the system. I´ve installed a sw recently that prompts for that, and when you select that server, then it prompts you to insert username and password, and then appears a dropdownlist again with the names of the databases of that sqlserver. Is this possible to do, at least fill dropdownlists with sqlservers and database names?!?I don't see how, thanks!

We are planning to move all of our System Center Databases that reside on front end servers to each system center application to a centrally located SQL 2012 server. We'd like to centralize everything and have our DBA care for the server. here is our setup:
SCOM has 1 monitoring and 1 Data warehouse server. SCCM has 1 server with all roles on it. DPM database is on the same server as Application. Same with SCVMM. I have 2 questions regarding this move:
1. Can I have all these databases running on 1 SQL instance?
2. Is there a best practice document that highlights steps and "gotchyas"

I have a report that was designed using SQL Reporting Services that sits on a SQL reporting server. It's nothing too exciting, it is essentially a three page application with legal jumbo on pages 2 and 3 and applicant data in fields on page 1.
We use rectangles to force page breaks to page 2 and to page 3.
When running the report on the report server, it shows and prints fine.
When running the report from the QA website internally, it shows and prints just fine.
When running the report from the production website from a machine internally, it shows and prints just fine.
When running the report from outside of the company network, the report is jacked. It obliterates large chunks of text, crams text together, and creates blank pages.
I need help in determining where I even begin with trouble shooting this!

can anyone tell me if they know of a way to automate the update process from development servers to live server, with little interference from an administrator
I have a development team that are constantly updating their databases along with their ASP code, and want to publish changes an a weekly basis. They have asked me for a way to take their new structures, tables, procedures etc, and copy them to the live servers, but NOT to interfere with existing customer data.
Funny I know – and I hate the idea btw :(
Any references, contacts, 3rd party tool recommendations welcome,
Thanx,
Darren

I am in the middle of a major migraton project, moving from x86 SQL 2000 to IA64 SQL 2005. I have a business need to link to several legacy servers. I have a number of problems I am trying to solve.
1) Linking a Kerberos server to a non-Kerberos server.
2) Linking x64 or IA64 servers to x86 servers.
3) Linking SQL 2005 to SQL 2000.
Two of the errors I am encountering are:
------------------------------
TCP Provider: An existing connection was forcibly closed by the remote host.
Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection.
OLE DB provider "SQLNCLI" for linked server "SCDC250DB" returned message "Communication link failure".
(Microsoft SQL Server, Error: 10054)
------------------------------
And
------------------------------
The OLE DB provider "SQLNCLI" for the linked server "SCDC250DB" reported an error. Authentication failed.
Cannot initialize the data source object of OLE DB provider "SQLNCLI" for linked server "SCDC250DB".
OLE DB provider "SQLCLI" for linked server "SCDC250DB" returned message "Invalid authorization specification".
(Microsoft SQL Server, Error: 7399)
If someone has worked through these problems before, I would appreciate it if you could direct me to the relevant documentation to resolve these issues.
Thanks!

Hi,
Can anyone give me any input on this. Recently TempDB one of my production server came down because tempDB got so big that it chewed up all the space in it's drive. My TempDB was in drive C:, where the Operating system and the rest of the SQL systems databases are(msdb,model,master). The actual production data are located in another logical RAID 5(Drive E:) Drive. I want to prevent the problem from happening again. Is it wise or does it degrade performance if i move TEMPDB from drive C: to drive E:? Is this going to cause a major bottom neck in drive E:, where the data are located?
Thank You for any help!
Eric

I am fairly versed with SQL 2005 as I have been using it since it came out. Now I have need to learn about Cubes.
Does anybody have any suggestions of where I need to begin to learn about what cubes are, how to create them and use them?
Ultimately we will be incorporating them into Reporting Services.
Thanks for the information.

I have a design that includes articles that will be searched. Obviously its too slow to put them into fields, and impossible because some have photos or are otherwise html documents. So I want to put pointers to their location.
Two questions. For each deployment, both desktop and web, where is the best place to put the articles. In any folder, or only in an iis virtual folder?

Hello all,I have an SQL query which retrieves a COUNT number from 2 different tables, and i want to do a division with botht he COUNT data retrieved. Trouble is I can't get it in the format that I want, my SQL query is as below :-SELECT ROUND( ((T1.Present/T2.Total ) * 100), 2) FROM(Select Count(Date) as Present from Attendance WHERE Month(Date)=12 AND Status=1) T1,(Select Count(Date) as Total from Attendance WHERE Month(Date)=12) T2The trouble here is that the result should be as below: T1.Present = 3T2.Total = 5 T1.Present/T2.Total = 3/5 = 0.6The final should be 60 after divided by 100But i am getting a zero as my result, even when I don't multiply the number by 100, the division result is still zero. I am guessing it is a conversion problem. Could anyone please offer me any advise on how to get the final result in the format I want?

One of our customers has a production and a test database. We are loading tables via a C++ program that works on production, but not on test, which is supposed to be an exact duplicate.
The error we are getting when trying to add columns to one of the table is 80004e21 null That is it.
When we load the exact same records in the production environment we do not get the error. We have spent many hours ensuring that the tables are exactly the same on test as in production.
Does anyone know, is there an environment variable at a database level that says how to handle null values?
Thanks!!!

Does anyone know if it is possible to use a variable in place of a database..table combination in a select statement
For Example: Instead of using the following with each database hardcoded in the SP:
select @dataused = sum(b.reserved)
from DBSglep..sysindexes b
where b.indid in (0, 1, 255) and segment != 2
I would like to loop for every database listed in sysdatabases and do this:
select @dbname = @dataname+'..sysindexes'
select @dataused = sum(b.reserved
from @dbname b
where b.indid in (0, 1, 255) and segment != 2
I have got the loop working, but just can't get the name substitution working as MSSQL dosn't seem to allow a variable after the FROM statement (it only seems to work with a hardcoded specific database..table name).
Any assistance in resolving this problem would be greatly appreciated! :-)
Many thanks in advance...
Regards,
Wayne

I have a very simple query that gets a field to use as constraints in another query.
Code:
SELECT A.RIN
FROM apcType T
INNER JOIN apcAttribute a on A.T = T.RIN
WHERE T.Name like '%Sales'
The results of the first query are used in the following query where it is bolded and marked with and <<<<========
Code:
SELECT AP.Arg2, AP.Arg3, M.Parcel,
M.Serial, M.Name, M.Acres, M.District,
V.YearBuilt, V.Code, V.Size,
(SELECT SUM(V1.Acres)
FROM TRValue V1
WHERE V1.Year = V.Year and V1.Parcel = V.Parcel and
SUBSTRING(V1.Code, 1, 1) = 'L'
[code]....
My question is How can I fold the first query into the second?

thanks for reading.
i'm wondering if i can use a stored procedure in place of a UDF in the case where i want a return value based on a simple calculation involving the input parameter.
i'd like to use this inline in a query somewhere else. that's why the UDF.
the UDF would be something like this ...
create function getFiscalYear (@when datetime)
returns int
as
BEGIN
declare @rv int
-- months of Oct, Nov, Dec are rolled into following year
if datepart(month, @when) >= 10
select @rv = datepart(year, @when) + 1
-- whereas all other months stay in this year
else
select @rv = datepart(year, @when)
end
END
so, the only reason i'm not using this UDF (and haven't tested it either) is because i can't find (or can't remember how :( ) to add a UDF to my database. when i run this code in Query Analyzer i get an error on the keyword "function". but that's another question altogether.
thanks in advance. (a) for helping with a stored procedure that does the equivalent or (b) nudging me in the right direction towards getting UDFs to work in my SQL 2000 install.

example
policy_number Policy_date_time Portfolio_set, status
12345 1/1/2011 1 I

I have many tables that have the same structure as the Employees table but have different names. I would like to pass the PS a paramater with the table name I want to process. My question is what is the correct syntax to use a parameter in place of the literals for the table name?
