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
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.
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.
Here 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
We are trying to create a TVF that executes a CLR Stored Procedure we wrote to use the results from the SP and transform them for the purposes of returning to the user as a table.

Help! Been doing the box step with BOL for several hours , Using tables in Adventureworks to create inline-table-valued function to provide a parameterized view of three JOINS - Have sucessfully created the function but can't figure out where to 'Declare' my variable "@SalesAgentID" need to be able to invoke the function with a particular ID - If you can help me cut this dance short I would REALLY Appreciate it.
View 7 Replies View RelatedOk, 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)
Hello Gurus,
I have a stored procedure that gathers data from three tables and joins them, two of the tables need to have different rowcounts set, ie. pull only a certain number of rows from one table and only a certain number of rows from another table... The number of rows it should pull are stored within a table for each. Let me explain.... these tables hold Exchange storage group and mailstore data for a number of servers. Each server has a table entry with the number of child storage groups and each storage group has a table entry with the number of child mailstores. The tables get updated every two minutes via a program. I need to be able to get the most Data with the correct child counts for each server and storage group.
I believe that i've found a way to do this with a stored procedure that calls a table-valued function. The table-valued function simply filters down the storage group table to it's number of storage groups, ordered by timestamp. I may be way off here, but i can't tell because both the stored procedure and function check out fine but when i execute the stored procedure it gives me the following error:
Cannot find either column "dbo" or the user-defined function or aggregate "dbo.GetExchSGInfo", or the name is ambiguous.
My code is below:
Stored Procedure:
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON

CREATE PROCEDURE [dbo].[GetExchangeData2]
@top INT,
@SID INT,
@SGCount INT,

Set @SID = (SELECT ServerID FROM dbo.Servers WHERE ServerName = @ServerName)
Set @top = (SELECT sum(Children) FROM dbo.ExchangeSG WHERE ServerID = @SID)
Set @SGCount = (SELECT SGCount FROM dbo.Servers WHERE ServerID = @SID)

I have some code that I need to run every quarter. I have many that are similar to this one so I wanted to input two parameters rather than searching and replacing the values. I have another stored procedure that's executed from this one that I will also parameter-ize. The problem I'm having is in embedding a parameter in the name of the called procedure (exec statement at the end of the code). I tried it as I'm showing and it errored. I tried googling but I couldn't find anything related to this. Maybe I just don't have the right keywords. what is the syntax?

View 2 Replies View RelatedHi 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."

I 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,

I have some SQL code as inline SQL (bad habit, I know). Now I want to convert this to an sproc, but I'm pretty much out of ideas here. The code looks like this:
string SQL = "SELECT * FROM MyDBTable WHERE 1=1";
if (txtMyField1.Text != "")
{
SQL = SQL + " AND MyField1 = @MyField";
}
if (txtMyField2.Text != "")
{
SQL = SQL + " AND MyField2 LIKE '%'+ @MyField2 + '%'";
}
if (txtMyField3.Text != "")
{
SQL = SQL + " AND MyField3 LIKE '%' + @MyField3 + '%'";
}
I have an search page built on ASP.NET 2.0. Based on what the user has entered to the form fields, the SQL in constructed on the fly. Since this is now inside codebehind file (aspx.cs), I want to get rid of it and move it to an sproc. But the question is how ? Some simple SQL clauses are easy to convert to an sproc but this is causing me lots of issues.

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.
I have a stored proc that is being executed from an OLE DB Source component in my Data Flow. Takes one input parm, has several variables declared within, a derived table which is used in a join and all within a try catch block with transaction handling. No updates, just returning data, works great, except now I have been asked to replace these stored procs with inline queries.
ALTER PROCEDURE [dbo].[usp_Get_Test]
(
@numberOfMonthsint
)
AS
BEGIN
SET NOCOUNT ON
set transaction isolation level read uncommitted
[Code] ....
The problems I have run into so far are...
SQL command text in OLE DB Source Editor does not like:
- TRY/CATCH block
- Will not let me use my input parm (@numberOfMonths int)
- When I hard code in my input parm (select @BeginDate = dateadd(MONTH, -1, GETDATE())) I can parse query and run the step but no results are returned. So I am let to assume that it does not like the @TESTY derived table.
The query here as a sample has had pivots removed as well, but research suggests this should be an issue in the SQL command text.
Also, I know not even to try the Build Query... cause it will complain about any variable declarations (i.e., declare @BeginDate datetime).
For instance, can I pull this off with an Execute SQL Task? The problem is I don't see this available in the toolbox for the Data Flow.
Also, would my error handling be done in the Event Handlers tab now and if so, is there a good example of this?
Hi,
i am encountering a problem in a stored procedure when a pass a variable value into a table-valued function. The table-valued function is named getCurrentDriver and has 1 attribute: car-ID.
The syntax is as follows:

(select driverName from getCurrentDriver(car.id)) as driverName
from car
When I try to compile I get following error on the line of the function:

What am I doing wrong? Is there a workaround for this error?
I am using SQL2005 EE with SP1. The server OS is windows 2K3 sp2
I have a table-valued function (E.g. findAllCustomer(Name varchar(100), gender varchar(1)) to join some tables and find out the result set base the the input parameters.
I have created indexes for the related joinning tables.
I would like to check the performance of a table-valued function and optimize the indexing columns by the execution plan.
I found the graphic explanation only show 1 icon to represent the function performance. I cannot find any further detail of the function. (E.g. using which index in joinning)
If I change the function to stored procedure, I can know whether the T-SQL is using index seek or table scan. I also found the stored procedure version subtree cost is much grether that the table-valued function
I would like to know any configureation in management studio can give more inform for the function performance?
Thanks
