Hello 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.
I 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.
Hi,
I'm trying to call a Stored Procedure from a Inline Table-Valued Function. Is it possible? If so can someone please tell me how? And also I would like to call this function from a view. Can it be possible? Any help is highly appreciated. Thanks
I'm attempting to convert some INSERT-EXEC structures into table-valued functions because the procedures are deeply nested and INSERT-EXEC doesn't like nesting (Error 3915: Cannot use the ROLLBACK statement within an INSERT-EXEC statement)
The procedure has a single select statement, so I created an inline table-valued function. When I ran it with sample data, I received this error (yes, twice):
Msg 0, Level 11, State 0, Line 0
A severe error occurred on the current command. The results, if any, should be discarded.
Msg 0, Level 20, State 0, Line 0
A severe error occurred on the current command. The results, if any, should be discarded.
After ruling out obvious mistakes, I started to deconstruct the select statement with its CTE and TVP. The result is the following, built in my local sandbox database:
CREATE TYPE test_list AS TABLE(a int);
GO
CREATE FUNCTION test_function (@p int, @theTable test_list READONLY)
RETURNS TABLE
AS
RETURN (
WITH cte
AS (SELECT a FROM @theTable)
SELECT cte.a
FROM cte);
GO
DECLARE @t test_list;
INSERT @t VALUES(1);
SELECT * FROM test_function(1, @t);
When I run this, I get the same error as noted above. I'm running on version 10.50.4000.0, Developer Edition. (2008 R2 SP2)
The function above does just about nothing and has redundancies because I stripped the actual function down to the essential elements to cause the error. The essential elements are:
- One of the parameters is a table-valued parameter (the UDTT definition does not seem to matter)
- The SELECT statement has a CTE
- The TVP is accessed within the CTE
- The outer FROM clause references the CTE
- There is also a scalar parameter on the function (scalar type does not seem to matter).
- The scalar parameter precedes the TVP in the parameter list.
So I have an easy work-around: put the TVP first in the parameter list.
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'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.
Hi all,
I've created a number of tables, views, sproc, and functions whose names begin with "sys_", but when I tried to create a multi-statement table-valued function with this type of name, I got:
Server: Msg 1706, Level 16, State 2, Procedure sys_tmp, Line 9
System table 'sys_test' was not created, because ad hoc updates to system catalogs are not enabled.
I had a quick look in this forum for 1706 (and on Google) but couldn't find anything. Does anyone know for certain if this is a bug in SQL2K?
Thanks, Jos

I 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?
Is it possible to pass multiple values to a TVF, such as using an IN clause?

I am forced to use a Sp in teh first place as my query is too long for the text dataset. I have a parameter Time_Period which ia a multivalued one but it is not allowing me to use this in the SP. using RS 2005.

Hello,
I am attempting to create a cascading parameter.
Parameter's 1 & 2 are multi-valued.
Datasets 1 & 2 supply Parameter's 1 & 2.
The values for Parameter 1 as derived from Dataset 1 are 'A', 'B', 'C', 'D' and 'E'.
The potential values for Parameter 2 will only be created if value 'C' is amongst the multiple values selected for Parameter 1.
Thus I need to write my query for Dataset 2 so that it can check the values of Parameter 1 for the existence of 'C' otherwise it returns nothing.
What is the best practice for a dataset referencing the values of a multi-valued parameter in order to generate it's resultset?
Any help is appreciated.
I want to set defaults for my multi-valued report parameter MONTH so that when the report starts, it automatically selects all the months prior to the current month (effectively creates a YTD report). However, using RS2005, I can't seem to figure out how to do this. I can create an IIF expression in 12 different value entries in the report parameters that returns the month based on the system date, but the first time I pass blanks, null or anything except a valid parameter, it clears the entire parameter list when the report displays.
Does anyone have any suggestions for auto-populating multiple values in a parameter at runtime where one or more of the parameter values may be empty? Checking "Allow Null" or "Allow Blank" doesn't fix this problem.
I tried to pass all the values in a single value entry on the report parameters page, but can't find the syntax that will allow this. I'm not sure if it will let you do that anyway...

Hi,
I am creating a data set for a ROLAP report which executes a dynamic SQL using EXEC. I am finding problems parameterizing multi-valued report parameters in the SQL being executed through EXEC.
To consider a sample code:
EXEC('select * from country where country_key in ('+@country+')')
where @country is a multi-valued report parameter.

I have a multi-valued parameter that I want to pass to a subreport. The values are 11, 12, 13, and 14.
So here's what I've done:
1. For the properties of the clickable field of the first report, I have gone to the Navigation tab and chosen the subreport in the "jump to report" pulldown.
2. Then I clicked on the Parameters button and added a parameter name for the multi-valued parameter I am trying to send. For the Parameter value, I have tried 11,12,13,14. I have also tried =Split(11,12,13,14)
3. On the subreport, I create a report parameter with the same name, data type is string, multi-value is checked, and the available values pulldown is populated by a query.
So I run the first report and click on the link that brings me to the subreport, but all the subreport shows is the results for 11, not 12, 13, and 14.
How can I get the second report to understand that I want it to show all the records related to 11, 12, 13, and 14? If I bypass the first report and simply use the drop-down to choose 11, 12, 13, and 14 in the subreport, it works fine. I just can't seem to figure out how to correctly have the first report tell the subreport that it wants 11, 12, 13, and 14.
Thanks in advance for any advice!

Hello Everyone,
I am trying to expand the multi-valued parameter menu object so I can display the selection list in a more user-friendly format since the text is fairly long. If left at the default setting then I have to scroll to the right to see the complete string(s). For a single-select parameter I can just CAST the string to CHAR(100) and the menu object will expand. However, it seems that this approach is not working for multi-valued parameter menu objects.
Is this a bug in SSRS, and is there another way to accomplish this. Please let me know.
Thank You!!!
How does one return all selected values in a multi-valued parameter? Right now i have a filter on the dataset where
(Expression)
=Fields!LOCATION_ID.Value
(Operator)
=
(Value)
=Parameters!Loc.Value(0)
This is just giving me data from the first value that is selected in the multi-valued dropdown. I need all returned from the parameter. Any ideas.
Hi There.
I have a Multi-valued parameter that is a string type and it freaks out when a do a select all from my drop down list. I suspect it has something to do with size as it works great if a pick a reasonable amount of items. My parameter list is populated by 1463 items of 12 characters each. Is there a threshold I should have to worry about?
Thanks, Mike
Hi All,
I'm having trouoble with changing my report name when I swtich to different parameter values.
I use the following expression.
IIf(Parameters!GroupVar1.Label = "CBank", "CBank", IIf(Parameters!GroupVar1.Value ="DTC","DTC","Total"))
This works fine when I clear Mutli-Value box in paramter properties. but when I use multi-value, this does not work.
Is there any solution for this?
Thanks
Hi All,
I'm unable to run the report the report with multi-valued parameter using the below StoredProcedure as dataset:

RETURN
And when I'm replacing this dataset to a query as below I'm able to run the report with multiple values selected for productid parameter :
select SalesOrderID,OrderQty,UnitPrice,ProductID

So, can anyone please help me out possibly using the same stored procedure as above.

I have an SSRS report with several variables, some of which are multi-valued. Â The main query that feeds the report uses some table value functions. Â For example, the query looks something like this:
select tv1.a, tv1.b, tv2.x, tv2.y, tbl.m, tbl.n
from tableValueFunction1(@MultiValueParam) as tv1
inner join tableValueFunction2(@MultiValueParam) as tv2 on tv1.xxx = tv2.xxx
inner join regularTable as tbl on tv1.xxx = tbl.xxx
where tbl.abc in (@MultiValueParam).When I try to run this, I get an error saying that I'm feeding the wrong number of parameters into the table value functions. Â I've fed multi-valued parameters to stored procedures before and used a splitter function to split out the comma separated values, so I was planning to do the same thing in this scenario. Â However, this is different. Â When I look at the query in SQL Profiler, it shows discrete values for the multi value parameter. Â For example, the same query above looks like this when viewed through the profiler (using 1,2,3 as my multi-value selection):
select tv1.a, tv1.b, tv2.x, tv3.y, tbl.m, tbl.n
from tableValueFunction1(1,2,3) as tv1
inner join tableValueFunction2(1,2,3) as tv2 on tv1.xxx = tv2.xxx
inner join regularTable as tbl on tv1.xxx = tbl.xxx
where tbl.abc in (1,2,3)
In other words, SSRS isn't converting the multi-value parameter to a comma separated string, like it normally does.
I have a sp where query is as below.
DECLARE @ServerCIName varchar(5000)
SELECT * FROMÂ dbo.INC
WHERE Status in ('Assigned','In Progress','Pending')
and Description like '%' + (Select * from SplitDelimiterString(@ServerName,',')) + '%'
and (select DATEADD(dd, DATEDIFF(dd, 0, (Submit_Date)), 0)) = (select DATEADD(dd, DATEDIFF(dd, 0, getdate()), 0))
In place of "and Description like '%' + (Select * from SplitDelimiterString(@ServerName,',')) + '%' ", if I use "and Description like '%' + @ServerName + '%' " and pass a single value, it works.
But @ServerName contains multiple values and it is dynamic (not constant).
How do I query the data?

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)

I have a report with the following dataset query:
Code Snippet
SELECT ...,

FROM ....
WHERE cast(detail.COUNTRY_ID as nvarchar(max)) IN (@countryId)
AND ...
GROUP BY ...
countryId is defined as a String multi-valued parameter.
The getActivitySinceBeginningYear is defined as follows:
Code Snippet
ALTER FUNCTION dbo.getActivitySinceBeginningYear
(
...
@countryId ntext,
...
)
RETURNS decimal(18,5)
AS
BEGIN
declare @return decimal(18,5)

inner join charlist_to_table(@countryId, Default) f on detail.COUNTRY_ID = f.str
WHERE ...
RETURN @return
END
This function works as expected if I transmit one ID or several.
The report works fine if I check only one ID.
If I check several IDs, the report displays this error:
Procedure or function dbo.getActivitySinceBeginningYear has too many arguments specified.
Why???
My second problem is with the Where clause:
Code Snippet

Code SnippetWHERE detail.COUNTRY_ID IN (@countryId)
I have the following error:

That's why I tried to use a cast, but the data returned by the query is wrong when I transmit several value.
