Using A Scalar Valued Function As A Parameter Of A Table Valued Function?
Feb 1, 2006Ok, 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)
SQL Server 2008 :: Recursive CTE On Inline Table Valued Function
Jun 22, 2015I have a recursive CTE on an inline table valued function. I need to set the MAXRECURSION option on the CTE, but SQL Server is complaining with "Incorrect syntax near the keyword 'OPTION'".
It works fine on non-inline function. I couldn't find any documentation indicating this wasn't possible.
I can use the MAXRECURSION option in call to the function
SELECT * FROM MyFunction ()
OPTION ( MAXRECURSION 0 )
but that means that the user needs to know the "MyFunction" uses recursive CTE, which defeats the purpose of the abstraction.

Inline Table-valued Function With Multi-value Parameter
Jul 18, 2007Hello everybody,
I need to create a function which takes a multi-value parameter. When I select more than one item, I get the error that I have too many arguments. Does anybody have a solution?
Or can I create a view and then do a "SELECT * FROM viewName WHERE columnName IN (@param)"?
Thanks in advance for your answers.
Table-valued Function Does Not Accept Chinese Characters As Parameter
Nov 15, 2007I have a table-valued function in mssql 2005 as below:
ALTER FUNCTION fn_test{ @test nvarchar(1000)}RETURNS@TEMP TABLE{ test nvarchar(1000)}ASBEGIN INSERT INTO @TEMP SELECT @test
RETURNEND
Everytime, I passed in chinese character (@test), such as 測驗, the function will return ????. What should I do for the table-valued function, so that the chinese character can be passed in? Please help.
Note: I can search and get the chinese characters if I use stored procedures; and the columns in the tables can store chinese chararcters as well. Only table-valued function is not working with the chinese characters. Is it a bug from MSSQL 2005?
Transact SQL :: Preserve And Return NULL For Non Matching Values From A Table Valued Function
Jun 29, 2015I have tables and a function as representated by the code below. The names for objects here are just for representation and not the actual names of objects.

When I run the following query, I get the required result except the rows for CID 500 for which PID is NULL in table T1. I want the rows for CID 500 as well with PID values as NULL.
SELECT A.CID,
A.ANI,

SQL Server 2012 :: Return Random Records In A Table-valued Function?
Dec 19, 2013My overarching goal is to generate sets of random Symptom records for each Enrollee in a drug study, so that for each cycle (period of time), the code will insert a random number of random records for each enrollee.
I'm trying to return a number of random records from a table, but inside a table-valued function... (which could be my problem).
CREATE FUNCTION dbo.ufn_GetTopSymptoms (
@enrollID INT
, @CTCVersion VARCHAR(20)
, @NumRecords INT
)
RETURNS TABLE
[Code] ....
But that ORDER BY NEWID() clause is illegal apparently, because here's the error it throws:
Msg 443, Level 16, State 1, Procedure ufn_GetTopSymptoms, Line 13
Invalid use of a side-effecting operator 'newid' within a function.
I was hoping I could return a set of enrollmentIDs and then use CROSS APPLY to generate a random set of records for each enrollmentID... is this not possible with APPLY? I was trying to avoid using a cursor...
The idea is basically to create all the Symptom records for all the patients in treatment cycle at once by using Enrollee OUTER APPLY dbo.ufn_GetTopSymtoms(dbo.Enrollment.EnrolleeID)
but that's clearly not working. Is there a way to do this without resorting to a cursor?

SQL XML :: Scalar Valued Function Slow Querying XML Passed As Parameter
May 28, 2015I 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)

View 2 Replies View RelatedHow To Join Using A Table-valued Function?
Oct 22, 2007Hi there. I've hit some gap in my SQL fundementals. I'm playing with table-valued functions but I can't figure out how to join those results with another table. I found another way to hit my immediate need with a scalar function, but ultimately I'm going to need to use some approach like this. What am I misunderstanding here?
The Given Objects:
function Split(stringToSplit, delimiter) returns table (column: token)
table Words (column: Words.word) -- table of predefined words
table Sentences (column: Sentences.sentence) -- table of sentences; tokens may not be in Words table, etc
The Problems:
1) how do I query a set of Sentences and their Tokens? (using Split)
2) how do I join tables Sentences and Words using the Split function?
The Attempts:
A)
select word, sentence, token
from Words,
Sentences,
dbo.Split(sentence, ' ') -- implicitly joins Split result with Sentences?
where word = token
resulting error: "'sentence' is not a recognized OPTIMIZER LOCK HINTS option."
B)
select word, sentence
from Words, Sentences
where word in (select token from dbo.Split(sentence, ' ')) -- correlated subquery?
resulting error: "'sentence' is not a recognized OPTIMIZER LOCK HINTS option."

Indexing Table-valued Function?
Aug 30, 2007I am using a multi-statement table-valued function to assemble data from several tables and views for a report. To do this, I INSERT data into the first few columns and then use UPDATEs to put data additional data into each row. Each UPDATE uses a WHERE criteria that identifies a unique row, based on the value of the first few columns.
The problem I'm having is that the UPDATEs are taking forever to execute. I believe the reason is that the temporary table that's created for the function is not indexed, so each row update requires a complete search of several columns.
In other situations I've been able to define one column as a primary key for the temporary table, but in this situation the primary key would have to consist of four columns, which doesn't seem to be allowed in the table definition for the function.
Is there any way to create indexes for the temporary tables that are created for multistatement table-valued functions? I think that would improve the UPDATE performance dramatically.
Thanks,

How Can I Assign Data Returned From A Stored Procedure Into The Return Table Of A Table Valued Function
Apr 18, 2007Here is the scenario,
I have 2 stored procedures, SP1 and SP2
SP1 has the following code:
declare @tmp as varchar(300)
set @tmp = 'SELECT * FROM
OPENROWSET ( ''SQLOLEDB'', ''SERVER=.;Trusted_Connection=yes'',
''SET FMTONLY OFF EXEC ' + db_name() + '..StoredProcedure'' )'
EXEC (@tmp)
SP2 has the following code:
SELECT *
FROM SP1 (which won't work because SP1 is a stored procedure. A view, a table valued function, or a temporary table must be used for this)
Views - can't use a view because they don't allow dynamic sql and the db_name() in the OPENROWSET function must be used.
Temp Tables - can't use these because it would cause a large hit on system performance due to the frequency SP2 and others like it will be used.
Functions - My last resort is to use a table valued function as shown:
FUNCTION MyFunction
( )
RETURNS @retTable
(
@Field1 int,
@Field2 varchar(50)
)
AS
BEGIN
-- the problem here is that I need to call SP1 and assign it's resulting data into the
-- @retTable variable
-- this statement is incorrect, but it's meaning is my goal
INSERT @retTableSELECT *FROM SP1
RETURN
END

Multi-statement Table-Valued Function
Oct 18, 2007I'm creating a Multi-statement Table-Valued Function...
Is it possible to insert variables into the table? In other words, is it possible
to have something like
declare
@value1 varchar(10)
@value2 varchar(10)
BEGIN
<do some work on value1 and value2>
INSERT @returningTable
@value1, @value2
instead of
BEGIN
<do some work on value1 and value2>
INSERT @returningTable
SELECT col1, col2 from T_SOURCE
Here's why I want to insert variables...My function needs to return a table which contains a 'partial' incremental key.
I'll go with an example to explain what i have to do
Source_table
col1 col2
Mike 10
Mike 20
Ben 50
John 15
John 25
John 35
The table that my function needs to create should look like this
col1 col2 col3
Mike 10 1
Mike 20 2
Ben 50 1
John 15 1
John 25 2
John 35 3
I thought of creating a cursor and then looping through it generate col3 and save values of other individual columns in variables. But don't know how to use those variables when inserting records into function table.
Any other ideas? I'm caoming from Oracle world, I might be having some strange ideas on how to solve this problem. Any help is appreciated.
Thank you.

Table-Valued Function Result Vs. Calculation Table
Jun 6, 2006
I need to return a table of values calculated from other tables. I have about 10 reports which will use approx. 6 different table structures.
Would it be better performance wise to create a physical table in the database to update while calculating using an identity field to id the stored procedure call, return the data and delete the records. For Example:
DataUserID, StrVal1,Strval2,StrVal4,IntVal1,IntVal2,FloatVal1...
Or using a table-valued function to return a temp table as the result.
I just dont know which overhead is worst, creating a table per function call, or using a defined table then deleting the result set per sp call.
