How To Avoid Using Scalar User Defined Functions
Sep 26, 2015Following the horrendous performance of Scalar UDFs demonstrated in this thread URL....(Scalar UDF 10x slower than writing the code, long hand, in the SELECT) I now have the worry that their widespread usage in my code needs to be refactored. I guess pretty much any single-line non-table-valued scalar-function would do
CREATE FUNCTION dbo.FNSafeString
(
@strValuevarchar(8000),-- STRING Value to convert to SAFE string
@intModeint = 0-- 0=NULL as '[NULL]', 1=NULL as ''
)
RETURNS varchar(8000)
WITH SCHEMABINDING
AS
BEGIN
RETURN COALESCE(@strValue,
CASE WHEN @intMode = 0
THEN '[NULL]'
ELSE ''
END
)
END
Its a little bit too big to really want to have to write it in each place where I need to use it, and its just big enough that it is worth centralising, and it might just be that I could code it more efficiently / different / handle more "edge cases" in the future.I do have even more straightforward UDFs - just to avoid typing something "Lengthy"
CREATE FUNCTION dbo.FNDateMidnight
(
@dtDateTimedatetime-- Date/Time Value to adjust
)
RETURNS datetime
WITH SCHEMABINDING
AS
BEGIN
RETURNDATEADD(Day, DATEDIFF(Day, 0, @dtDateTime)+1, 0)
END
Perhaps I should consider changing them to inline table valued functions, or CROSS APPLY them? but I can't think of a way to centralised them and re-use the code WITHOUT a function, can I?
How To Avoid The Need Of Adding User In Administrator Group.
Oct 5, 2006Hi,
I've created an rdl report in reporting services 2005. Report is working fine. I've deployed this report on SQL Server 2005. The problem is this that to access the reports from client, I need to add client's login ID in Administrator user's group os server. If I dont add them in that group, it shows following error:
"The permissions granted to user 'loginname' are insufficient for performing this operation. (rsAccessDenied)".
This solution works fine in development but in actual environment, I can't add users in that group. Can anyone tell me how to view reports without adding user in administrator group. Its urgent.
Looking forward for help.
How Can We Avoid Somebody To Access The MDF Data By Doing User Instance Connection?
Dec 11, 2006I created a database that will be distributed to my customers. This database is running on an Instance of SQL Server 2005 Express edition. I removed the admin logins from my SQL Server Instance so in theory, only my application connecting itself using the Sql Server autenthication will be able to be access the data (using "sa" having a password that I set at the installation).
For now, all this is working fine and after some tests, I haven't been able to access the data in any ways except by using the "sa" and the password my app is the only one to know.
But the problem is coming from a security leak when using User Instance. Indeed, I've been able to create a program getting the content from my MDF file. If somebody try to get connected using User Instance on his own SQL Server instance, he will be able to reach the data.
How could I prevent this to happend? Is there a property or something that could be set into the database that would prevent the database (mdf file) to be used with User Instance?
Thanks!
Change Connected User To Avoid Owner Prefix In Queries
Mar 16, 2007Hi everybody,I've five instances of SQL Server 2000 with the SAME database with aDIFFERENT owner in each server. I, as the administrator, have a lot ofqueries that I have to execute in some or all servers. The problem isthat I have to connect to all servers with MY user, not each of the dbowners...So I have queries this way:select * from mike.table1 t1 join mike.table2 t2 on...And when I connect to another server I have to change mike for jeremyin all the SQLs...And when I connect to another server I have to change jeremy for ninain all the SQLs...I know that there was an old, v7, deprecated way to change the"schema", something likechange current user to kimberlygoselect * from table1 t1 join table2 t2 on...This way, I'll change ONLY once the connected user. I could even do atthe beginning of the script an IF, to change the connected userdepending on @@SERVERNAME !!!Can someone remember this instruction???Thanks in advance for your help !!!

Jan 23, 2007 Hi,
I have several reports for users to view on our Intranet. After installation of SQL 2005 SP2 patch, I cannot delete user or user's authority from Report in Properties Tab. An error message was shown on the status bar. It indicated that JavaScript Error: 'Return' statement outside of function. Seems something wrong with the 'Delete' funciton in SQL 2005 after update. The other functions worked fine. Could you point me out how to fix it or need to install any updates / hotfix. Thanks a lot!

Searching A Column For A Value To Avoid Inserting A Duplicate Value
Jul 17, 2007Hi there, newbie here.
I'm building a web application that allows for tagging of items, using ASP.NET 2.0, C# and SQL Server.
I have my USERS, ITEMS and TAGS separated out into three tables, with an intersection table to connect them.
Imagine a user has found an item they are interested in and is about to tag it. They type their tag into a textbox and hit Enter.
Here's what I want to do:
I want to search the TagText column in my TAGS table, to see if the chosen tag is already in the table. If it is, the existing entry will be used in the new relationship the user is creating. Thus I avoid inserting a duplicate value in this column and save space. If the value is not already in the column, a new entry will be created.
Here's where I'm up to:
I can type a tag into a textbox and then feed it to a query, which returns any matches to a GridView control.
Now I'm stuck... I imagine I have to use "if else" scenario, but I'm unsure of the code I'll have to use. I also think that maybe ADO.NET could help me here, but I have not yet delved into this. Can anyone give me a few pointers to help me along?
Cheers!

Jun 18, 2007Hi all,
(I am using SQL Server 2005)
I have created a new 'CUSTOMERS' table and created a colum 'CustomerID' as an Identity column.
Now, a problem I find is that when I delete a particular record, its Identity value is used automatically for the New record I insert later!
I do not want to re-use the already used Identity value.
I just want to have the last CustomerID to be higher that all the previous ones.
Is there any way to do this?

Cannot Add Windows User, Cannot Delete Sql User
Jul 23, 2005We were using sql authentication on our sql server 2000 servers, Butneed to use windows authentication. I have an sql user jdoe that ownsmany different objects in multiple databases. I have tried adding thewindows login of jdoe with the exact same permissions as the sql userjdoe, but it complains because it says jdoe already exists. So Iattempt to delete the sql user of jdoe (remembering the permissions soI can reapply them to the windows user soon to be created) But it says"you cannot drop the selected login id because that login id ownsobjects in one or more databases" So now I am trying to figure out howto change the ownership of those many many objects in the manydatabases from jdoe to dbo so I can delete this sql user of jdoe. Doesanyone know of a way to convert an sql login to a windows login? Or ifthat can't be done, how to change the owner of many objects to dbo so Ican delete this user? Maybe a T-SQL script or stored procedure. Thereis a stored procedure called sp_changeobjectowner but that only worksfor one object, how would I do that on all the objects that jdoe owns?As you can see I am a newbie but I appreciate any help you canprovide!!! Thanks in advance!

Unable To Delete User
Aug 27, 2007When trying to delete a user on SQL server 2000, we recieve the message "You cannot drop the selected login ID because that login ID owns objects in one or more databases."
We've tried a number of operations to find the objects owned by the user by searching for this error message in Google but, none of those suggestions work.
My questions are; Why does this happen, How can we avoid it in the future?
Our software applicaiton is case sensistive, and if a SQL security login is not created that matches the Domain login to the method used in the application - somehow we are suck. We can't create a new security for the login, nor can we delete or use the existing one.

SQL Server Express 2005 - How To Delete/drop A User Instance
May 23, 2008Hi,
I have been working around with SQL Server Express 2005 on VISTA. I created a small C++2008 application which interface with SSE 2005. When running my application, it automatically created a user instance which I would like to get rid of. I just forgot from start to set "User Instance = False" in my connectionstring. (oups...)
I'm aware, from readings I did, that a couple of tables as well as log files, etc. are created under directory "utilisateurs...AppDataLocalMicrosoftMicrosoft SQL Server DataSQLEXPRESS". SQLEXPRESS is the instance name chosen during install of SSE2005.
Also using following SQL Statement:
select owning_principal_name, instance_pipe_name, heart_beat
from sys.dm_os_child_instances
I got following result:
owning_principal_name: PC-DE-STEPHANEStéphane
instance_pipe_name: \.pipe6172F4E8-622E-4A sqlquery
heart_beat: dead (at this moment...)
==> How can I make a good cleanup of all this as well as get rid of the user instance itself?
Thanks in advance for any help.

Delete Partial From Column
Jan 30, 2006Guys, i have a table that one of the columns (Email To) is
a concatenated list of email addresses separated by semi colons ";".
i.e.:
rrb7@yahoo.com;richard.butcher@sthou.com;administr ator@sthou.com
etc like that.
each row varies with one exception. administrator@sthou.com is in each one.
is there a simple way thru sql or T-SQL to delete that "administrator@sthou.com" part? or should i call each row individually into say, a VB.net form using a split with the deliminator ";"
and then looping thru and updating each row?
thanks again for any easy answer
