SQL Server 2012 :: How To Use Scalar Function Without WHILE
Jan 19, 2014
I 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?

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 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

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.

I've a scalar function which is killing my performance. I've been used the SQL profiler and also DMVs to catch execution information. I'd like to store the value received by this function and also the time that it happened, but I can't think in a way to do it.

As an example, I have a scalar function called TRIM that takes a VARCHAR parameter, does a LTRIM(TRIM(VARCHAR)), and returns the result.
How can I call this function from java using JDBC? I have only had luck calling basic stored procedures, but I need to call functions as well.
Thanks, Ken

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':
System.Data.SqlTypes.SqlNullValueException: Data is Null. This method or property cannot be called on Null values.
System.Data.SqlTypes.SqlNullValueException:
at System.Data.SqlTypes.SqlInt64.get_Value()
at System.Data.SqlTypes.SqlInt64.op_Explicit(SqlInt64 x)
at Informed.DCLG.IRS.SQL.IncidentTransform.Lookup.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.
Thanks,
Jan.

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 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?

Hi, I'm having trouble with this multi-statement table-valued function:

Pims.NABP = @arTemp.NABP AND
Pims.NumRx = @arTemp.NumRx

INSERT INTO @arDetail SELECT * FROM @arTemp
RETURN
END
GO
I get
Msg 137, Level 15, State 2, Procedure MakeArDetail, Line 43
Must declare the scalar variable "@arTemp".
I don't understand why SQL thinks @arTemp is a scalar variable which has to be declared.
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 have the following query that supposes to merge multiple result in a single one and put it into a temporary table:
SELECT DISTINCT [AlphaExtension],
STUFF((SELECT A.[NoteText] + '< BR />' FROM #temp A
WHERE A.[AlphaExtension]=B.[AlphaExtension]
FOR XML PATH('')),1,1,'') As [NoteText]
FROM #temp B
GROUP BY [AlphaExtension], [NoteText]
It is working fine unless by a simple detail. If you look at the second line of the query you will see that I am stuffing together a < BR /> tag (break line) because the contents of the field is going to be spitted directly to the screen and I want that the multiple results be displayed in different lines.
OK, the issue is that it is stuffing & lt ; BR / & gt ; instead < BR /> and therefore the browser is displaying the tag instead to break a line.

I have a function that accepts a date parameter and uses getdate() as its default value. If a date is passed in, I'm going to have to find records using the datediff method based on input. If no date is passed, I am going to bypass the datediff logic and search for records based on a column called "is_current" which will reduce the query time.
However, I don't know how to tell if the date value in the function came from an input or was the default.

I have a question regarding windowing functions. I have a sales order table with the columns "orderid", "customerid", "order_date" and "amount". I use the following query to get the amount of every customer as a additional column:
Select customerid,
orderid,
order_date,
amount,
SUM(amount) OVER (PARTITION BY customerid)
FROM sales_orders
My question is if there is a good way to add another column, which includes the SUM(amount) of the customerid, where the order_date > 2012-01-15 , something like this:
Select customerid,
orderid,
order_date,
amount,
SUM(amount) OVER (PARTITION BY customerid),
SUM(amount) OVER (PARTITION BY customerid WHERE order_date > 2012-01-15)
FROM sales_orders
I know, this is not a valid method, so do you know a way to achieve this? Can I maybe use CROSS APPLY or something like this? I know that I could use a subquery to get this, but is there maybe a way / a better way via window functions?

I have the following data stored in a column in a table:
£10,000.00 & ' " % < > Guðmundsdóttir Björk Lårs Marqués María-Jose Carreño Quiñones
I query this in a stored procedure using the FOR XML clause and universal table, and store the result in an XML data type variable:
DECLARE@ResultXML
EXECUTE[someStoredProcedure] @Result OUTPUT
This data (as XML) is then written to a file; in order to do this, I CONVERT the data to NVARCHAR since there are unicode characters in the source:
DECLARE@strResultNVARCHAR(MAX)
SET@strResult= CONVERT( NVARCHAR( MAX ), @Result, 1 )
Now this works fine, except on inspection, SQLServer has decided to render the data thus:
£10,000.00 & ' " % < > Guðmundsdóttir Björk Lårs Marqués María-Jose Carreño Quiñones
Why it has changed the apos and quot entities to the corresponding character but not the other entities is beyond me.
how to preserve XML entities?

In t-sql 2012, the followinng sql works fine when I declare @reportID.
IF @reportID <> 0
BEGIN
SELECT 'Students report 1' AS selectRptName, 1 AS rptNumValue
UNION
SELECT 'Students report 2', 2
UNION
[code]...
However when I use the sql above in an ssrs 2012 report, the query does not work since the @reportID parameter can have 0, 1, or up to 200 values.Thus I am thinking of calling the following following function to split out the parameter values:
FUNCTION [dbo].[fn_splitString]
(
@listString VARCHAR(MAX)
)
RETURNS TABLE WITH SCHEMABINDING
AS
RETURN
(
SELECT SUBSTRING(l.listString, sn.Num + 1, CHARINDEX(',', l.listString, sn.Num + 1) - sn.Num - 1) _id
FROM (SELECT ',' + LTRIM(RTRIM(@listString)) + ',' AS listString) l
CROSS JOIN dbo.sequenceNumbers sn
WHERE sn.Num < LEN(l.listString)
AND SUBSTRING(l.listString, sn.Num, 1) = ','
)
GO
how to remove the @reportID <> 0 t-sql above and replace by calling the fn_splitString function?

The value that you are passing is numeric and numeric with only decimal 0 value, and then convert it to integer otherwise leave as it is

Select value, fn_convertointerger(value) as converted_value from TableA

The code is working good. However i want the return type to be dynamic. If the data type supplied is integer then i want to return a integer value like 0 if its null. if the data value is varchar then i want to return 'No Data'.
