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:

CREATE FUNCTION dbo.MyTest() RETURNS INT

when I run:
SELECT dbo.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 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 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:
alter FUNCTION spGet_Rec_Count
(
@source_tbl varchar(100)
)
RETURNS bigint
AS
BEGIN
-- Declare the return variable here
DECLARE @count bigint
-- Add the T-SQL statements to compute the return value here
select @count = (select count(*) from [member_score] where source_tbl = ''' + @tbl + ''')
-- Return the result of the function
RETURN @count
END
GO
I get zero regardless of where @count is declared as in or bigint.
I have 2 Tables as below,
1) Purchase_Invoice
a. PurchaseInvoiceID
b. SupplierName
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?

If I don't include the UPDATE command the thing works.
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
[Code] ....
The two versions of the SP
CREATE PROCEDURE [dbo].[FastProcedure]
AS
BEGIN
SET NOCOUNT ON;
select
dbo.FastFunction(al.Detaljer)

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.
I'm having trouble with the UDF's I had in SQL 2000 that were migrated to SQL 2005 under the SCALAR FUNCTION item. Before in 2000 you just created the UDF, named it and saved. IN SQL 2005 you create/modify and then have to save it as a .SQL file to a folder. First of all, what folder should it go to so that all can use and secondly, when I do this and run the functions it doesn't work... I need to modify the scalar function and
save it with out saving to a .SQL file. How do I do this or is this the new way to create/modify functions. Any help is much appreciated
thanks
What is the definition of a scalar value in a relational database?

{string selectCmd = "SELECT SUM(hours) FROM tasks WHERE project=@project";
string strConnection = ConfigurationManager.ConnectionStrings["TimeAccountingConnectionString"].ConnectionString;SqlConnection myConnection = new SqlConnection(strConnection);
SqlCommand myCommand = new SqlCommand(selectCmd, myConnection);myCommand.Parameters.Add(new SqlParameter("@project", SqlDbType.VarChar));myCommand.Parameters["@project"].Value = project;
myConnection.Open();float total = (float)myCommand.ExecuteScalar();
myConnection.Close();
return total;

Hi everyone,
I am getting that infamous message on an INSERT Sql query. I am doing everything right by the looks of it. All variables are either passed in through a custom form, or else declared and initialised in the body of the script.
I post the relevent code below:
SQLsqlInsertEmail = "INSERT INTO CandidateLogins (SiteID, LoginName, CandidateEmail, DateRegistered) " & _" VALUES (@SiteID, @LoginName, @CandidateEmail, @DateRegistered); SELECT SCOPE_IDENTITY()"Try sqlSetCandidateEmail.Parameters.Add(New SqlParameter("@SiteID", SqlDbType.Int)) sqlSetCandidateEmail.Parameters("@SiteID").Value = SiteID sqlSetCandidateEmail.Parameters.Add(New SqlParameter("@LoginName", SqlDbType.VarChar)) sqlSetCandidateEmail.Parameters("@LoginName").Value = userName sqlSetCandidateEmail.Parameters.Add(New SqlParameter("@CandidateEmail", SqlDbType.VarChar)) sqlSetCandidateEmail.Parameters("@CandidateEmail").Value = email sqlSetCandidateEmail.Parameters.Add(New SqlParameter("@DateRegistered", SqlDbType.DateTime)) sqlSetCandidateEmail.Parameters("@DateRegistered").Value = DateRegistered sqlSetCandidateEmail = New SqlCommand(sqlInsertEmail, C4LConnection)
C4LConnection.Open() CandidateID = sqlSetCandidateEmail.ExecuteScalar()
Catch Exp As SqlException lblResults.Visible = True lblResults.Text = "Unable to Register Jobseeker: " & Exp.MessageFinallyC4LConnection.Close()End Try
All the variables passed into the SQL statement are initialised, with SiteID beign set to '0', rather than Null (none of the fields are Nullable in the database table) and I have checked that the SqlDbType's correspend to the Table Definition
So far as I can discern, everything is correct and as can be seen, I am not using a stored procedure in this instance, but the script falls over be producing the error message "Must Declare Scalar @SiteID", even though SiteID is declared as Int32 further up in the script.
Any help would be appreciated.
My question is: can I use GETDATE function in  scalar UDF as below:
CREATE FUNCTION dbo.GetDateFunction()
RETURNS DateTime
AS
BEGIN
  RETURN GetDate();
END
I have seen this UDF definition in tutorial,but I thought non-deterministic functions can not be used in UDF.
I also looked at two sites to find out but both says differently:
Technet: [URL] ... states that functions that return different values on each call can not be used in UDF.
MSDN: [URL] .... states that  nondeterministic built-in functions can be used in Transact-SQL user-defined functions and in the list of functions GETDATE is listed.
How to verify which one is true?

Many Thanks in advance
I have a stored procedure that I'm trying too, and must figure out how to convert it to a view. The stored procedure uses two scalar variable for a date range in the WHERE CLAUSE (@StartDate and @EndDate). What can we do in a view if we cannot hard code date ranges? If I use the date field (Paydate) in the view then I cannot get a sum of the Payamt.
I appreciate your help.

I tried to execute above sproc in SQL Server Management Studio , I received the error: Must declare the scalar variable "@Score1".
Hey Guys, I am creating a scalar function for the first time. I have googled, ck'd your FAQ's, looked 2 text books but cannot find the answer to my questions.
Is the IF statement used in the Scalar function like it is in the stored procedure. In other words does it have to return a Boolean? I want to perform a loop after I call the function, do I have to use a Cursor? Or can I code it like a VB function with a FOR/DO While? Also I can call this UDF from my Stored Proc, right?
Here is a quick synopsis of what I have been assigned to do:
--- Calculate Run Dates
--(start from Previous Saturday subtract 41 days
-- if the 41st day does not fall on a Saturday (day = 7)
-- keep subtracting days until Day=Saturday. Add 6 days to make
-- END date the following Friday)
Thanx,

OK i have my stored procedure all set up and working.. But when i try and add a second variable called @iuser and then after i execute the stored procedure, i get an error saying:-
ERROR
"Must declare scalar variable @iuser"
Here is the code i am using in my stored proc, also my stored proc worked fine before i used a second variable??!
//BEGIN
ALTER PROCEDURE [dbo].[putpending]
(@cuuser nvarchar(1000), @iuser nvarchar(1000))
AS
Declare @sql nvarchar(1000)
SELECT @sql =
'INSERT INTO ' +
@cuuser +
' (Pending) VALUES (@iuser)'
EXECUTE (@sql)
RETURN
//END
And i know my VB.NET code is working but i will put it in anyway:-
//BEGIN
'variables
Dim user As String
user = Profile.UserName
Dim intenduser As String
intenduser = DetailsView1.Rows(0).Cells(1).Text.ToString()
'connection settings
Dim cs As String
cs = "Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|friends.mdf;Integrated Security=True;User Instance=True"
Dim scn As New SqlConnection(cs)
'parameters
Dim cmd As New SqlCommand("putpending", scn)
cmd.CommandType = CommandType.StoredProcedure
cmd.Parameters.Add("@cuuser", SqlDbType.NVarChar, 1000)
cmd.Parameters("@cuuser").Value = user
cmd.Parameters.Add("@iuser", SqlDbType.NVarChar, 1000)
cmd.Parameters("@iuser").Value = intenduser
'execute
scn.Open()
cmd.ExecuteNonQuery()
scn.Close()
//END
Any ideas why i am getting this error message?
