Resolving Function USER
Mar 24, 2006If I log in to Query Analyzer using Windows Auth and run "PRINT USER", it returns "dbo". Is there any way to have the USER function actually return <Domain><login> for myself?

Resolving IP To Machine Names
Feb 3, 2006Hi,
I am exploring with data drawn from a network monitoring box and would like to translate the IP addresses in that data to machine names. The SQL server that has the data also has a linked server to our AD.
Is there anyway that anyone knows of resolving IP to machine name via AD? and .... can i do this via 'SELECT blah from OpenQuery (ADSI, 'Select blah ....) ????
any ideas on how i might resolve this greatly welcomed.
Alternatively, can i get DNS records into a file that i can import to SQL for the lookup?
thanks

Help Convert MS Access Function To MS SQL User Defined Function
Aug 1, 2005I have this function in access I need to be able to use in ms sql. Having problems trying to get it to work. The function gets rid of the leading zeros if the field being past dosn't have any non number characters.For example:TrimZero("000000001023") > "1023"TrimZero("E1025") > "E1025"TrimZero("000000021021") > "21021"TrimZero("R5545") > "R5545"Here is the function that works in access:Public Function TrimZero(strField As Variant) As String Dim strReturn As String If IsNull(strField) = True Then strReturn = "" Else strReturn = strField Do While Left(strReturn, 1) = "0" strReturn = Mid(strReturn, 2) Loop End If TrimZero = strReturnEnd Function

Feb 11, 2006HiOur product uses MS-SQL Server 2000. One of our customer has 10installations with each installation stroring data in its own database.Now the customer wants to consolidate these databases into one and wealready have plan for that by consolidating one DB at a time. But firstthey want to find how many unique or duplicate entries they have acrossall the 10 databasesAssumptions:1. All the databases reside on the same server. (This is just anassumption, not the real environment at customer site)2. Databases can not be merged before it is found how many unique orduplicate rows exist.Table under consideration:Message(HashID PK,....)# of rows in Message table in each of databases: 1 MillionHere is my question: How can I find how many unique or duplicateentries they have across all the 10 databases. I easily find uniquerows for two databases with a query like this:SELECT COUNT(A.HasID) FROM db1.dbo.Message A LEFT OUTER JOIN ONdb2.dbo.Message B ON A.HashID = B.HashID WHERE B.HashID IS NULLHow can I do this for 10 databases. This will require factorial of 10queries to solve this problem.I will appreciate if someone can provide hint on this.RegardsAK

SQL 2012 :: AlwaysOn Secondary Replica - Resolving State
May 21, 2013I have an AlwaysOn Availability group configured between 2 nodes (Synchronous)
Automatic failover was working fine until recently
I can failover between the nodes manually but automatic failover doesn't seem to be working. In my earlier test, I would shut down the SQL Service on the primary and within seconds, the secondary replica would take over. Recently I have performed the same test and the secondary replica enters the resolving state and the DB in unavailable.
I have tried everything here: [URL] ....
The only change I made was changing the availability mode from Synchronous to Asynchronous - Could that be the cause?
SQL 2012 :: AlwaysOn Availability Group Listener DNS Resolving To DR Node
Jan 19, 2015We are rolling out the use of Availability Group listeners to our SQL Server 2012 Environment which has a 2 node multi-subnet cluster. The Primary is R/W and the Secondary is a non-readable node that would be manually failed over to in a DR scenario
I have set up the AGL and asked the sysadmins to create a DNS record in both subnets with fixed IP's.
The issue I have having is that when I ask the app developers to connect to the databases using the AGL it is totally random whether the AGL resolves to the Primary or DR node - as a result that are having problems getting their apps to connect.
I was thinking of asking the sys admins to remove the DNS record in the DR subnet and then add it back in should we need to fail over - but I was thinking there must be a better way.
User ID Function
Jul 17, 2007Greetings all
I have a question on using this function to limit the information to an individual. I've used this before on a report so that when an individual logs in he sees only his information. Now for this report I want a supervisor to only see his subordinates. Am I right in my train of thought here? I should be able to establish a relationship between the supervisor_id and the employee to limit the report to only his group?
thanks in advance -- if someone has done something similar to this and can share some specifics that would be great

Jan 10, 2007I have a UDF that takes my input and returns the next valid business day date. My valid date excludes weekends and holidays.
It works perfect except for one issue. It doesn't check to see if today's date is a holiday.
I pass a query to sql server like so " select dbo.getstartdate('01/ 10/2007',2)"
It then moves ahead two business days and returns that date.
Here is the current code. Hopefully someone can tell me how to do the holiday check on the current date.

I am tring to pass acomma delimited string to a function and this function is parsing the string so that I can see individual values so for example I am passing 1,2,3,4,5 as a parameter to my function and I am parsing this string so that I can write something like this

It is working fine. Only problem is if the user passes word 'all' instead of 1,2,3,4 then I have to doSelect * from tableA
My function looks like this. How can I modify this function if I pass 'all' as a paramater. Any help will be appreciated.CREATE FUNCTION [dbo].[ParseText2File] (@p_text varchar(4000), @p_Delimeter char(1))

User Defined Function
Aug 2, 1999Dear friends,
I am a new user for SQL server. Coming from an oracle background, I find it very difficult to live without user defined functions. At the moment, I urgently need to have a function returning an custom-made ID string, so that it can be used in one of my stored procedures. I have heard the rumours that SQL server 7 does NOT support user defined functions, (which SQL 6.5 does). I would be really grateful if anyone can clarify this for me, and if possible, suggest a get-around approach.
Thanks in advance!

Jun 23, 2004I am trying to compare the data from one table (shipments) with the data from a view. The point of the function is to match the correct territory with the account depending on the data. Basically, I this deals with accounts that are transfering from one territory to another.

Can someone tell me how I can get this to work and insert a territory ID for the account that has transfered into the shipments table?
CREATE FUNCTION fnShipments ()

I want the UDF to do the following for me
Return in hours the difference between what the user has send and now (lets say now = '10 Nov 2004 11:00:00')
So the UDF will return to me 20.
But I dont want 20, I want the UDF to avoid any all hours which are not work related (any time after 16h00
until 8h00 in the morning), so I want this UDF to return 4. That means from '9 Nov 2004 15:00:00' I have calculated
1hr until 16h00 and 3hrs from 8 until 11h00 on '10 Nov 2004 11:00:00'
AGAIN IT MUST NOT CALCULATE WEEKENDS. Lets say '12 Nov 2004 15:00:00' was Friday and now = '15 Nov 2004 11:00:00', I must still
get 4 as a return from UDF
I would also like now to be my getdate(), but it seems like you can't use it in UDF

Apr 6, 2006I am accustomed to doing most of my function work in Access, but the boss would really like it if I could shedule some cubes to do the stuff that takes forever when you run it live.
To that end, I have an Access function that I call to get a field value for a query. I would like to be able to create an User Defined Function on the SQL server and call that function as a field value in a view. I have searched the forums and have not really found anything that wants to make sense to me as to how to do this.
The access function is as follows:
Public Function BuyerDeltas(IFSDate As Date, PODate As Date) As Long
If IFSDate < (Date + 14) Then
BuyerDeltas = IFSDate - 3 - PODate
ElseIf IFSDate < (Date + 29) Then
BuyerDeltas = IFSDate - 7 - PODate
ElseIf IFSDate > (Date + 28) Then
BuyerDeltas = IFSDate - 10 - PODate
Else
MsgBox "This should not be possible!", vbOKOnly, "Fix It!!!!!!!"
End If
End Function
The view that this is called from contains the IFSDate and PODate fields and I am able to call the function from the access query, but this is completely different than what I have seen in the help files on SQL.
I would love to be able to keep plugging away at doing this myself, but the boss also is pushing me to get it done and he doesn't want me taking forever to do it.
Any direction would be greatly appreciated!
Calling The User Defined Function!!!
Aug 28, 2007hai,
the problem is - I have created a userdefined function using SQL 2000
create function getfulldate (@date varchar(10))returns datetimeasbegindeclare @getfulldate datetime set @getfulldate = dateadd (mi,55,@date)
return @getfulldateend
and normally we call this in the SQL statements as
select *, dbo.getfulldate('2006-05-03') from emp
This works fine and what I need was, I need to invoke the user-defined function like
select *, getfulldate('2006-05-03') from emp that is, without using "dbo".
If I call in that manner, it gives error as - 'getfulldate' is not a recognized function name.
So, here what is the purpose of dbo and can I call in my desired manner as mentioned above.
anyone guide me, thanks!

Need Help Optizing A User Defined Function
Mar 3, 2004Hi,
I posted a question sometime back about any one has written a function which converts a given date to a a new timezone.
As it turns out I have actually written the function and it is functionally sound.
the issue I am not facing is the performace.
The Algorithm is pretty simple.
step 1
I have create a table called TZ1 which has the TImezoneCODE (PST,EST..), daylightsavingsstart (DATETIME on which the daylight savings start), daylightsavingsend ( end of DLS) and offset (EG -8 for PST, -5 for EST etc)
step 2
I check the timezone and pick out corresponding start and enddate for daylight savings.
Step 3
Depending on where the date lies I create a new date by adding offset to the original datetime (+1) for the new date and then return this new datetime.
As simple as this looks the response time is 16 times than that of a select statement without the function.
Do you see something that I can tune to get a better response time.
Heres my code

It should returnsomething similiar to:Column1 Column2 UDFColumn1 SomeValue 02 OtherValue 13 DifferentValue 04 LastValue 1After reading some of the posts and discovering you can't executedynamic SQL in a UDF I decided to split the function into a functionand stored procedure:CREATE FUNCTION dbo.SelectedByApplication(@ApplicationID int,@TableToChecknvarchar(50),@ColumnToComparenvarchar(50),@ValueInTableint)RETURNS BIT ASBEGINDeclare @Result INTEXEC DynamicCompare @ApplicationID, @TableToCheck, @ColumnToCompare,@ValueInTable, @Resultif(@Result > 0)return 1return 0ENDCREATE PROCEDURE dbo.DynamicCompare(@ApplicationID int,@TableToChecknvarchar(50),@ColumnToComparenvarchar(50),@ValueInTableint,@Resultint out)ASDECLARE @SQLNVARCHAR(1000)DECLARE @Param NVARCHAR(500)SET @SQL = N'SELECT @result = COUNT(*) FROM [' + @TableToCheck + ']' +'WHERE [' + @ColumnToCompare + '] = @ValueInTable ANDApplicationID = @ApplicationID'SET @Param = N'@result int out, @ValueInTable int, @ApplicationIDint'EXECUTE sp_executesql @SQL, @Param, @result out, @ValueInTable,@ApplicationIDI get the same error message about only being able to execute functionsand extended stored procedures in a user defined function.Does anyone have any ideas as to how I can dynamically execute thisquery? The reason I say dynamic is I need this same comparison forabout 25 different tables. Thanks!

Jul 20, 2005Is it possible to call a user-defined function without prefixing itwith 'dbo.' within a SELECT clause somehow? Just curious; it's not abig issue but just a stylistic one for me.Thanks!Joel Thornton ~ <groups@joelpt.eml.cc>

Jul 20, 2005I have a user defined function that may be called multiple times inthe same query - here's a rough exampleselect col1, get_random_number(), col2, col3, get_random_number() fromtable1The problem I am having is that I need to have both calls to the userdefined function return the same value if it is called multiple timesfor one row. The values returned from the query would be somethig likethis -John 23456 Engineer Junior 23456Frank 33333 Engineer Senior 33333Tom 80331 Engineer Junior 80331I have thought about having two seperate udf's likeget_random_number() and use_last_random_number(), but I'm not sure howto store the value of the get_random_number() to be used byuse_last_random_number(). These udfs are used in bulk load requests,so performance is a big issue. Any suggestions would be greatlyappreciated. I know the example is kind of silly, but I think itillustrates the problem.
