Hi, I am using Sql Server 2005 as the database management and Access 2003 as the front-end. In the database, I intend to give different views of tables to different users. That's why I used suser_sname system function, which returns the windows login id and authenticates users to see different records in the same view. What I want to do in Access is, allowing some specific users to be able to do update, insert and delete operations through a form based on this view (which only depends on 1 table). However, Access tells me that "the recordset is not updateable". In order to be able to change records, I tried to create new index for the view in Sql Server, which failed giving "Sql Server, Error number:1949" and telling me that it fails since suser_sname yields non-deterministic results. The strange thing is that when I open VB Editor in Access and write a simple update code within this form, it updates both the view and the table in the database. My question is: How can I do update, delete and insert operations on the form directly? Is there a way to do the authentication without using a nondeterministic function in Sql Server or using the front-end Access 2003? Maybe a function similar to the current_user function in Access can do that, I don't know.
It's been a long question but I desperately need the answer. Any thanks will be appreciated.

Determinism Deterministic functions always return the same result any time they are called with a specific set of input values and given the same state of the database. Nondeterministic functions may return different results each time they are called with a specific set of input values even if the database state that they access remains the same. The Database Engine automatically analyzes the body of Transact-SQL functions and evaluates whether the function is deterministic. For example, if the function calls other functions that are non-deterministic, or if the function calls extended stored procedures, then the Database Engine marks the function as non-deterministic. For common language runtime (CLR) functions, the Database Engine relies on the author of the function to mark the function as deterministic or not using the SqlFunction custom attribute.
Now my question. When wouldn't a function return the same result under these circumstances? When wouldn't any query do this for that matter? What would possibly cause different result sets when the same input parameters are supplied?
"Deterministic functions always return the same result any time they are called with a specific set of input values and given the same state of the database.

Shows whether the data type of the selected column can be determined with certainty. (Applies only to Microsoft SQL Server 2000 or later.) This is what Microsoft documentation says for this column property. How I can use his feature for database application development? What is the practical use of this property?
I am new to SQL Server and am migrating another database
In my original database I have a default(constant) type field and a calculated field both of which call the same user defined function: GetMyUID()
My Function GetMyUID() returns the current date, time and users initials, i.e. "20080522T09:31:15.250LSG"
When a record is first created both fields have identical values
As the record is updated over time my constant field stays constant and my calculated field reflects the time the record was last updated and the initials of that person. So my first field is called 'Created' and my second is called 'Updated'
I would have thought that something like this would be a pretty bog standard and very straightforward requirement in any database
However in SQL I am getting error messages about the return value being non deterministic
I searched the web and found advice that to sort the problem I need to use WITH SCHEMABINDING in my function definition
Unfortunately I am still getting the same 'non deterministic' error
I wonder if (in the quest to not have an overlong field) by looking up the persons initials from a 'STAFF' file rather than leaving the username in full tacked on to the end that this is causing the problem?
I can't imagine that what I am trying to achieve is rocket science but unfortunately have not been able to find any resource on the web that solves this issue for me
In desperation I turn to you
Please help (preferably by letting me have a few lines of code that return the current date/time followed by the username lookup of a Username's initials, here is a snippet of my code...
I 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
I need to be able to pass the output of a function to another function as input, where all functions involved are user-defined in-line table-valued functions. I already posted this on Stack Exchange, so here is a link to the relevant code: [URL] ...
I am fairly certain OUTER APPLY is the core answer here; there's *clearly* some way in which does *not* do what I need, or I would not get the null output you see in the link, but it seems clear that there should be a way to fool it into working.
Can anybody know ,how can we add builtin functions(ROW_NUMBER()) of Sql Server 2005 into database library. I get this error when i used into storeprocedure : ROW_NUMBER() function is not recognized in store procedure. i used MS SQL SERVER 2005 , so i think "ROW_FUNCTION()" is not in MS SQL SERVER 2005 database library. I need to add that function into MS SQL SERVER 2005 database library. Can anbody know how we can add that function into MS SQL SERVER 2005 database library?
I want to write function to call another function which name isparameter to first function. Other parameters should be passed tocalled function.If I call it function('f1',10) it should call f1(10). If I call itfunction('f2',5) it should call f2(5).So far i tried something likeCREATE FUNCTION [dbo].[func] (@f varchar(50),@m money)RETURNS varchar(50) ASBEGINreturn(select 'dbo.'+@f+'('+convert(varchar(50),@m)+')')ENDWhen I call it select dbo.formuła('f_test',1000) it returns'select f_test(1000)', but not value of f_test(1000).What's wrong?Mariusz
Ok, I'm pretty knowledgable about T-SQL, but I've hit something that seems should work, but just doesn't... I'm writing a stored procedure that needs to use the primary key fields of a table that is being passed to me so that I can generate what will most likely be a dynamically generated SQL statement and then execute it. So the first thing I do, is I need to grab the primary key fields of the table. I'd rather not go down to the base system tables since we may (hopefully) upgrade this one SQL 2000 machine to 2005 fairly soon, so I poke around, and find sp_pkeys in the master table. Great. I pass in the table name, and sure enough, it comes back with a record set, 1 row per column. That's exactly what I need. Umm... This is the part where I'm at a loss. The stored procedure outputs the resultset as a resultset (Not as an output param). Now I want to use that list in my stored procedure, thinking that if the base tables change, Microsoft will change the stored procedure accordingly, so even after a version upgrade my stuff SHOULD still work. But... How do I use the resultset from the stored procedure? You can't reference it like a table-valued function, nor can you 'capture' the resultset for use using the syntax like: DECLARE @table table@table=EXEC sp_pkeys MyTable That of course just returns you the RETURN_VALUE instead of the resultset it output. Ugh. Ok, so I finally decide to just bite the bullet, and I grab the code from sp_pkeys and make my own little function called fn_pkeys. Since I might also want to be able to 'force' the primary keys (Maybe the table doesn't really have one, but logically it does), I decide it'll pass back a comma-delimited varchar of columns that make up the primary key. Ok, I test it and it works great. Now, I'm happily going along and building my routine, and realize, hey, I don't really want that in a comma-delimited varchar, I want to use it in one of my queries, and I have this nice little table-valued function I call split, that takes a comma-delimited varchar, and returns a table... So I preceed to try it out... SELECT *FROM Split(fn_pkeys('MyTable'),DEFAULT) Syntax Error. Ugh. Eventually, I even try: SELECT *FROM Split(substring('abc,def',2,6),DEFAULT) Syntax Error. Hmm...What am I doing wrong here, or can't you use a scalar-valued function as a parameter into a table-valued function? SELECT *FROM Split('bc,def',DEFAULT) works just fine. So my questions are: Is there any way to programmatically capture a resultset that is being output from a stored procedure for use in the stored procedure that called it? Is there any way to pass a scalar-valued function as a parameter into a table-valued function? Oh, this works as well as a work around, but I'm more interested in if there is a way without having to workaround: DECLARE @tmp varchar(8000) SET @tmp=(SELECT dbo.fn_pkeys('MyTable')) SELECT * FROM Split(@tmp,DEFAULT)
Yesterday Peso was gracious enough to help me with creating function/views/sp's
I took those examples and extended what had from excel into function in SQL
however I see myself repeating certain parts of the query and i'm wondering if there is a way to call a function (in part or in whole) from another function?
Here are excerpts two functions I have:
We'll call this function UserUsage() ------------------------------------ RETURN( SELECT ut.LastName, ut.FirstName, CEILING(Sum(hu.session_time)/ 60000) AS [Time Spent(MIN)], Max(hu.time_stamp) AS [Last Log Date], pct.Title, cat.topic_name FROM ZSRIVENDEL.dbo.UserTable ut, ZSRIVENDEL.dbo.history_usage hu, ZSRIVENDEL.dbo.pc_CourseTitles pct, ZSRIVENDEL.dbo.cam_topics cat WHERE ut.student_id = hu.student_id AND hu.course_id = pct.CourseID AND hu.topic_id = cat.topic_id AND ((ut.ClientID=@ClientID) AND (pct.ClientID=@ClientID) AND (ut.GroupID=3400) AND (hu.time_stamp>= @StartDate And hu.time_stamp< @EndDate) AND (hu.session_time<21600000)) GROUP BY ut.LastName, ut.FirstName, pct.Title, cat.topic_name )
and will call this function UserSummary(): ----------------------------------------- RETURN ( SELECTut.LastName, ut.FirstName, CEILING(SUM(hu.Session_Time) / 60000.0) AS [Time Spent(MIN)] FROM ZSRIVENDEL.dbo.UserTable AS ut INNER JOIN ZSRIVENDEL.dbo.History_Usage AS hu ON hu.Student_ID = ut.Student_ID WHERE ut.ClientID = @ClientID AND ut.GroupID = 3400 AND hu.Time_Stamp >= @StartDate AND hu.Time_Stamp < @EndDate AND hu.Session_Time < 21600000 GROUP BY ut.LastName, ut.FirstName )
As you can see the first part of the both query are simlar. In particular the:
SELECTut.LastName, ut.FirstName, CEILING(SUM(hu.Session_Time) / 60000.0) AS [Time Spent(MIN)]
and also the variables @StartDate and @EndDate.
In C# it would create a method and just call that method as well as the variables. However i'm not sure how to do that with sql functions. Could someone shed some light please?
Hi,I have written a stored proc with some temporary tables and also useda getdate() in my stored proc. When i try to call the sproc the erroris that we can only use extended sprocs or function inside a sproc.Now if try to write the stored proc directly inside a fuction ie copypaste after changing my temp tables to tables the problem is , i get aerror invalid use of getdate in sproc.What do i do to get somethingfor my results inside a table.Thanks in advance.RVG
I have a table:tblRateUserUserIDJudge intUserIDJudged intscore int this table contains the userid of the person giving a score (judge) and the person receiving the score (judged) and the score itself. Each user can only score another user once. tblRateUser content:judged judge score6 5 87 5 107 6 515 7 415 5 9 When a new score is inserted I want to get the average score for the rated user by counting all scores for that user and divide by the number of records. declare @avgscore decimal(4,1) set @avgscore=(select avg(score) from tblRateUser WHERE UserCodeJudged=@ID) print 'avg score: '+ cast(@avgscore as nvarchar(15)) in the above example this results for usercode judged 7 in an average score of 7.0 whereas I would expect 7.5 (10+5)/2 what am I doing wrong?
I have this scalar -valued function in sql called dbo.GetGoodCustomer ALTER function [dbo].[GetGoodCustomer](@client_id int)returns numeric(10, 2)asbegin declare @getgoodcustomer as numeric(10, 2) declare @review_type as int select @review_type = item_num from customers where client_id = @client_id if @review_type = 0 begin select @getgoodcustomer = getgoodcustomer from customers where client_id = @client_id end if @review_type > 0 begin select @getgoodcustomer = l.g from customers c inner join detail l on c.client_id = l.client_id where c.client_id = @client_Id and c.item_num = l.item_num endReturn @getgoodcustomerendNow, how can I use this function in asp.net (vb.net) ?Because whatever is getgoodcustomer would give me I need to display that in datagrid's text box.Loop thru datagrid If CType(dgItem.FindControl("txtID"), TextBox).Text = 13 ThenDim txtgoodcustomer As TextBox = CType(dgItem.FindControl("txtcust"), TextBox)basically amount returns from function would be showing in txtcust textbox.I don't know I have never done this before..
DECLARE @TotalAmount AS INTEGER DECLARE @TotalPoints As INTEGER SELECT @TotalAmount = SUM(Amount) From Rewards WHERE MemberID = @MemberID AND Redeemed = 1 @TotalPoints = @TotalAmount MOD 20

SQL Server has no Last() and Max() pulls the Max not the last. Is there a way to pull the Last payment amount with the date of that payment, in SQL Server????
I'm creating DTS packages to load data from text files. I'm finding that a lot of the data needs to be transformed in the same way (e.g trailing "." removed). Rather than writing individual activex scripts to do this, is it possible to write my own DTS function which I call from my DTS packages?
I am upgrading an AccessXP database to SQL 2000 and have an issue with week numbers.
There is currently a piece of VBA that calculates the week number for time recording purposes using the DatePart function as DefaultVal_WeekNo = DatePart("ww", TaxDate, vbMonday, vbFirstFourDays)
I have tried to get this replicated in SQL by using
declare @TaxDate as datetime declare @TheWeek float
set @TaxDate = @TheDate -90 -7
set @TheWeek = cast(datepart("ww",@TheDate) as numeric (30)) - cast(datediff("wk", @TaxDate, @TheDate) as numeric (30))
but this is not reurning the correct values, i belive this is because the VB function has the vbMonday argument. Can anyone tell me how i can get wround this please?
We have len() function in some of our stored procedures. Why one of our SQL servers (6.5) will not recognize this function while others do? While we transfer the stored procedures, the stored procedure can not be transfered to the database of that server. Your immediate help will be appreciated. Su
I am having some difficulty with the Max function. I would expect it to return one row when you use it in a select statement (as long as there is truly one unique row)
Executing the query below give me the following result

I have a function dbo.Validlan which is takes 4 paramentes: par1,par2,par3,par4 I would like to select all 4 at run time: SELECT par1,par2,par3,par4 FROM table1 t1 INNER JOIN table2 t2 ON t1.enrl=t2.enrl
I have the following problem statement: Quote: What was the most expensive merchandise item sold in July? Display sale date, sale price and merchandise description. Sort output by descending sales price. (hard-coding date is OK). Here's my query statement: Code:
SELECT saleDate AS "Sale Date", salePrice AS "Sale Price",description AS "Merchandise Description"FROM Sale, SaleItem, MerchandiseWHERE salePriceAND DATENAME(MONTH, dateBorn) = 'July'ORDER BY salePrice DESC
I want to know how I would use the MAX function on my query since I know this would give me the most expensive item. Am I writing my query statement correctly? Do I have to declare the MAX function in the SELECT statement and on the WHERE statement of just on the WHERE statement? Any clarifications/help would be appreciated
