I wrote a Scalar UDF in SQL2005 that returns an integer. I want to be able to display this integer in a ASP.Net 2.0 web page. I typically use a DAL for all data so I added an ObjectDataSource as a Qeury that contains only the UDF. How do I easily display the value in a Label Control or?
I have tried to use a Repeater with a label, a Formview with a Label, all to no avail. Any suggestions?
I want to add four fields of a table and place the toatal in a new field.Also I wanna have the average of the fields.
For e.g
I have created a marksheet having four subjects.Now I wanna add the subjects and find the average of the subjects and place them in two different fields in the same table along with the respective names in the table.Pls help.
Thanks in advance.
I build a UDF scalar function like this:
CREATE FUNCTION VerificaAcessoPerfil
(
@codigo INT
)
RETURNS INT
[Code] ....
Curiously when i call my function the same one return always the same value, ex:
Select VerificaAcessoPerfil(2)
the return value is : 698 ??
but if i run the Select statment like this:
SELECT DISTINCT codigo,
(case codigo WHEN 1 THEN 695
WHEN 11 THEN 697 WHEN 2 THEN 211
WHEN 10 THEN 698 WHEN 13 THEN 696
WHEN 4 THEN 1 END)[codigo]
FROM pf (NOLOCK) INNER JOIN pfu (NOLOCK) ON pfu.pfstamp=pf.pfstamp
WHERE codigo IN (1,11,2,10,13,4)
ORDER BY 1 ASC
The value are:
1695
2211
41
10698
11697
13696
Is it ill-advised to have columns whose values pull from scalar functionsusing other fields in the record as parameters? For example, if I havecreate table a(iID int primary key)create table b(iID int ,iDetail int,CONSTRAINT PK PRIMARY KEY(iID,iDetail),CONSTRAINT FK FOREIGN KEY (iID) REFERENCES a(iID))Let's say in table b I put price information for each detail and in table aI'd like to put a column that sums these prices for the children of eachrecord. Should I make a computed column that references a function usingiID as a parameter? Or would it be better to create a view for this kind ofpurpose?Regards,Tyler
View 4 Replies View RelatedI have a scalar function, which calculates the similarity of two strings. I use the following query, to compare the entries of one table against the value 'Test' and return the entries, which have a value > 50:
;WITH cte1 AS (
SELECT b.FirstName,
(SELECT fn_similarity('Test', b.FirstName)) AS [Value],
b.LastName
FROM [AdventureWorks2012].[Person].[Person] b
)
SELECT *
FROM cte1
WHERE [Value] > 50.00
ORDER BY [Value] DESC
Now I want to use this query against the first 50 entries of the [Person] table, so that the resultset includes all the values of the first 50 persons and the entries, which are similar to them.
At the moment I use a WHILE-loop and write the five single resultsets in a temporary table. Is there another way / a better way, maybe via a join?
Hi, I have the follow function:
CREATE FUNCTION [dbo].[ToTime]
(
@intHora int, --A valid hour
@intMin int -- A valid minute
)
RETURNS smalldatetime
AS
BEGIN
declare @strTime smalldatetime
declare @errorvar int
select @strTime=cast(convert(varchar,cast((cast(@intHora as varchar) +':'+ cast(@intMin as varchar)) as smalldatetime),108) as varchar)
return @strTime;
END
the function works perfect but when the parameter for the hour is a negative number (for example -1), or a number > 23
and the parameter for the minute is an negative number (-1) or a number > 59, the function produce an error.
I need handle this error converting the wrong value in 0, but i don't want to do this using "if statement". for example
if @intHora < 0 or @intHora >23
begin
set @intHora = 0
end
if @intMin <0 or @intMin>59
begin
set @intMin = 0
end
please, If someone know some sql function (try - catch doesn't work) to handle this kind of error or some good way to do it, please help me.

Hi,
I have an assembly that contains the following function:
Public Class Lookup
<SqlFunction()> _
Public Shared Function MyTest() As Integer
Return System.Data.SqlTypes.SqlInt64.Null
End Function
End Class
Then in SSMS:
CREATE ASSEMBLY IRS_MyTest
FROM '\machine empmyAssembly.dll'
GO
CREATE FUNCTION dbo.MyTest() RETURNS INT
AS EXTERNAL NAME IRS_MyTest.[MyClass].MyTest
GO
when I run:
SELECT dbo.MyTest()
the following is returned:
Msg 6522, Level 16, State 2, Line 1
A .NET Framework error occurred during execution of user defined routine or aggregate 'MyTest':

Can anyone please advise on how to return back a null value. Currently, my only other option is to return nothing (actually returns 0) and then wrap this up to convert the value to null - not ideal.

I have created a local user on Report Server Computer and the user has the administrative rights.
When i try to connect Report Server (http://xxx.xxx.xxx.xxx/reportserver) with this user's credantials. (ReportServer directory security is set -only- to Basic Authentication. ).

I have this code:
Declare @sql as varchar(4000)
declare @tbl as varchar(100)
declare @exists as bit
select @tbl = 'ACA_RSF'
select @sql = 'select count(*) from [member_score] where source_tbl = ''' + @tbl + ''''
print @sql
exec (@sql)
and it returns 18 million for a record count.I have this scalar returning function, which models the above, and it returns zero:
select dbo.fnGet_Rec_Count('ACA_RSF') as cnt
here is the code:

-- Add the T-SQL statements to compute the return value here
select @count = (select count(*) from [member_score] where source_tbl = ''' + @tbl + ''')

I get zero regardless of where @count is declared as in or bigint.
I have 2 Tables as below,

c. BillNo
d. BillDate
2) Purchase_Invoice_Items
a. PurchaseInvoiceItemID
b. PurhcaseInvoiceID (FK to Purchase_Invoice Table)
c. ItemName
d. Quantity
e. Rate
Now I want to select all the records of Purhcase_Invoice table exactly once with one column at last containing comma separated Item name of particular PurhcaseInvoiceID as below
PurchaseInvoiceID | SupplierName | BillNo | BillDate | Items (Comma Separated Items)
Currently I am using Scalar Function which takes PurchaseInvoiceID as Argument and Returns Comma Separated Itemnames€¦
It works well but when number of records are large than performance is very poor.
Is there another way of doing same thing? By Join or By some System Function?

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)
I have a procedure that calls a SVF to convert an xmldocument. The ultimate purpose is to update the xml in a column in a multi-million row table. The xml is stored as varchar(MAX), it was supposed to carry any type of text, initially at least.
My question is: why is the xml-parsing performed inside the function much slower when i pass the xmldocument as type xml than when it is passed as varchar(MAX) and the CAST to xml is within the function? Does processing the xml input parameter in SlowFunction involve expensive crossing of some context border?
The two versions of the SVF (they return the rowcount in this simplified example):
CREATE FUNCTION [dbo].[FastFunction]
(
@inDetaljerText varchar(MAX)
)
RETURNS int

Hi There,
I need to call a function to calculate a value. This function accepts a varchar parameter and returns a boolean value. I need to call this function for each row in the dataflow task. I thought I would use an oledb command transformation and for some reason if I say..
'select functioname(?)' as the sqlcommand, it gives me an error message at the design time. In the input/output properties, I have mapped Param_0(external column) to an input column.
I get this erro.."syntax error, ermission violation or other non specific error". Can somebiody please suggest me what's wrong with this and how should I deal this.
Thanks a lot!!
Dear all,
Basically I want to set chain up the rights so that the anonymous web user IUSR_ .. can execute the new .NET subs, functions etc in the assembly, just as the anonymous web user can execute Stored Procedures when granted. In this way, it should be possible to call the .NET assembly just as classic stored procedures from ASP/ASP.NET.
I have written a .NET function which I can successfully execute if I log on to the database as an administrator by sending this T-SQL query; it returns the result of a given string:
select dbo.CLRHTMLString('abc')
The scenario is now to try to grant access to this assembly for a different role (webuser), which the classic IUSR_MYSERVERNAME is a login of, so that I can call the .NET Assembly when I am authenticated as the anonymous web user (e.g. via ASP, etc.).
To test access, I created a login (webusertest) for a user (webusertest) in the same role (webuser) on the database. But when I use this login, which supposedly has the same rights as the IUSR_, execution right is denied:
EXECUTE permission denied on object 'CLRHTMLString', database 'adt_db', schema 'dbo'.
Note: The 'webuser' database role has Execute permission on the Assembly.
I have also tested this from my actual web page, with the following results:
(1) IUSR_MYSERVER member of db_owner role: Web page has right to call assembly.
(2) IUSR_MYSERVER not member of db_owner role: Web page does not have right to call assembly.
Further test results:
(3) Function can be called when making the user "webusertest" member of the "db_owner" role, which is too much rights to grant for the anonymous web user.
(4) When adding the user 'webusertest' to get 'Execute' permissions on the assembly, it does not get added. After clicking OK, there is no warning message, but when opening the Assembly Properties -> Permission dialog box the same time, the 'webusertest' user does not appear in the list.
Thankful for any advice on this matter.

View 2 Replies View RelatedThe stored procedure takes ~ 10 seconds every call. The execution plan is Index seek or clustered index scan almost everywhere . No table spools or lazy loads or key lookups. Cannot share the code or execution plan due to company rules and regulations.Issue is that i am dealing with result set of around 50,000 records . Out of these i have to return 20 records at a single time (which is also customizable i.e 40 / 60/ 150 records in a page). Application cannot handle all 50k records so i have to return 20 records for every stored procedure call.
The result set changes as per the start date and end date which i recieve as parameters. In application there are few Column filters namely- Country(around 50 countries), Outcome(around 6 to 10 values ) . These filters will values in drop down( as excel ) depending on the distinct values in that columns. These filters will be populated on every page, if no filter value is selected.Issue is if user does sorting or filtering any records , this stored procedure is called and every time i have to deal with ~50000 records.
Current Code :
Step 1 ) Get the required result set in temp table .
Step 2) Compute the results on some business rules . (Outcome and SharesAvailable calculation - see attachment)
Step 3) populate filter Columns (Country,Outcome) these values will be comma seperated.
Step 4) Dynamic query to get required result set i.e if user wants only 10 records in single page then TOP 10 . Sorting can be applied on any column mentioned in screenshot.

Where - in SQL Server Profiler - can I see the port number that someone has used to connect to a database?

I would like to run a SELECT statement using the SQLCMD, however, I do not like the count of records be displayed after the execution. How do I do that?
Thanks in advance.
I've got a stored procedure that processes a TON of records...
What I would liek to do is to write a row to a "progress" table which shows how many rows have actually been processed.
I have a simple counter defined in the procedure:
SET @COUNTER = 0
Each time the procedure loops through, it increments by 1:
SET @COUNTER = @COUNTER + 1
What I would like to do is write rows to a PROCESS table which would reads:
PROCESSED 1000 rows
PROCESSED 2000 rows
PROCESSED ...... rows
etc.
I have a slight idea how to pull this off, but not sure about the whole even number thing by 1000.
If anyone has any insight it would be greatly appreciated!!
Thanks in advance!
Hello,
I am working on a project that displays images. Before you can get to the image, you have to select a category that the image may be in. After that, you select the sub categories. I am trying to display a count of the number of records that the subcategories contain. Here is an example:
The user can make a selection from the categories listed below:
Geographic Area
Time Period
Topic
Record Type
If the user selects time period, he/she is taken to a list of subcategories. I would like to display the subcategories with a count of the number of records that will be displayed if it is selected. Listed below is an example of what this would look like:
Colonial (10) -----the number in parenthesis is the number of records that will be displayed if selected------
Gilded Age (12)
Revolutionary (9)
Progressive Era (22)
Is there a way to display the number in parenthesis using ASP.Net and SQL Server 2000? Any clues will be greatly appreciated.
Thanks
I'm stuck on converting a datetime field to Int. Basically, one of the fields in the select returns the datetime of a journey. However I need to be able to add up the number of days for a specific person who done that journey, e.g. it will return 21/08/2014, 22/08/2014 etc...
I then need to total up the days as a new field to display the number of days.
Can you do this by converting a datetime to int then use COUNT on the int?
