Pass Output Of A Function To Another Function As Input
Jan 7, 2014
I need to be able to pass the output of a function to another function as input, where all functions involved are user-defined in-line table-valued functions. I already posted this on Stack Exchange, so here is a link to the relevant code: [URL] ...
I am fairly certain OUTER APPLY is the core answer here; there's *clearly* some way in which does *not* do what I need, or I would not get the null output you see in the link, but it seems clear that there should be a way to fool it into working.

i want to make a function that will take a table as input parameter. this table will be the output of a stored procedure. while i were writing the function i have an error and when i read about it i found that i can not send a table as input parameter to a function till i create a new TYPE of this table with its columns and data types as UDT but i found that sql server 2005 does not support the type 'table'...
my question now is it possible technically to make this function? is it possible to write something like that :
SELECT dbo.MyFunction(exec dbo.MystoredProc)
and in my function i am using CLR-Integration as this :
create function MyFunction
(
@TempTable table
(
ContractID int,
ContractNumber nvarchar(20),
Name_En nvarchar(80),
Name_Ar nvarchar(80),
ContractAmount money,
CurrencyID nchar(3),
DateStart smalldatetime,
DateEnd smalldatetime,
Currency_En nvarchar(30),
Currency_Ar nvarchar(30)
)
)
returns table( ContractNumber nvarchar(20),
Name_En nvarchar(80),
Name_Ar nvarchar(80),
ContractAmount decimal,
Currency_En nvarchar(30),
Currency_Ar nvarchar(30),
[Year] int,
[Month] int,
DomesticAmount decimal
)
as external name [AssemblyName].[PathOfTheFunctionInTheAssembly].[FunctionNameInAssembly]
please help me in this code as i need it urgently...
thanks in advance,

I am trying to use a Execute SQL task in which I call a query and get back a scalar value. I THINK I have it set up correctly, yet I am getting a very unhelpful error message of:
Error: 0xC002F210 at Determine Previous Trade Date, Execute SQL Task: Executing the query "SELECT[Supporting].[dbo].[fGetOffsetTradeDate](?, -1) AS [PreviousTradeDate]" failed with the following error: "Syntax error, permission violation, or other nonspecific error". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.
The Parameter Mapping has a single INPUT entry of data type DATE mapped to parameter 0.
The Result Set property (in General) is set to Single Row and there is a single entry in the Result Set config which maps [PreviousTradeDate] to a variable.
Odd thing is, if I replace the ? in the query with a date (say '03/24/2006') everything works fine. This would indicate that my query syntax is fine.

Hi,
I have a problem passing the resultset of a query to a function.
so I started like this:
DECLARE @idoc as int, @MyResultset as ????,@StartPath as nvarchar(50);
set @StartPath ='nodes/node'
EXEC sp_xml_preparedocument @idoc output,@XML_IN
set @MyResultset =(select * from OPENXML(@idoc,@startpath,2))
select fn_myfunction( @MyResultset); -- get the recursive path for example
but this don't work.
Do i have to use a temporary table or is there any way to do it with parameters?
Thanks in advance

In the snippet below, ExecuteSqlString is a stored procedure that accepts one parameter. SelectChangeDropdownRowsource is a function in my code behind page that generates the string I want to pass. I can't seem to find the correct syntax to get it to work. The way it is show below, the error comes back about incorrect syntax near ')' . Is this doable?

I would like to wrap the following code in a function and reuse it. I use this code in many triggers.
DECLARE @Action as char(1);
SET @Action = (CASE WHEN EXISTS(SELECT * FROM INSERTED) AND EXISTS(SELECT * FROM DELETED)
THEN 'U' -- Set Action to Updated.
WHEN EXISTS(SELECT * FROM INSERTED)
THEN 'I' -- Set Action to Insert.
WHEN EXISTS(SELECT * FROM DELETED)
THEN 'D' -- Set Action to Deleted.
ELSE NULL -- Skip. It may have been a "failed delete".
END)
Is it possible to write a function and pass the INSERTED and DELETED logical tables to it?

I would like to create a function that take a value and run some logic and output the value
I have a table like this
Table A
value
*
001
004.00
3.0
1.22
Logic I want to run is
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
So if I run a query something like this
Select value, fn_convertointerger(value) as converted_value from TableA
I will get
Value converted_value
* *
001 1
004.00 4
3.0 3
1.22 1.22
2.02 2.02
4.000 4

I'm using SS 2012.
I started with an inline table returning function with a hard coded input table name. This works fine, but my boss wants me to generalize the function, to give it in input table parameter. That's where I'm running into problems.
In one forum, someone suggested that an input parameter for a table is possible in 2012, and the example I saw used "sysname" as the parameter type. It didn't like that. I tried "table" for the parameter type. It didn't like that.
The other suggestion was to use dynamic sql, which I assume means I can no longer use an inline function.
This means switching to the multi-line function, which I will if I have to, but those are more tedious.
Any syntax for using the inline function to accomplish this, or am I stuck with multi-line?
A simple example of what I'm trying to do is below:
Create FUNCTION [CSH388102].[fnTest]
(
-- Add the parameters for the function here
@Source_Tbl sysname
)
RETURNS TABLE
AS
RETURN
(
select @Source_Tbl.yr from @Source_Tbl
)
Error I get is:
Msg 1087, Level 16, State 1, Procedure fnTest, Line 12
Must declare the table variable "@Source_Tbl".
If I use "table" as the parameter type, it gives me:
Msg 156, Level 15, State 1, Procedure fnTest, Line 4
Incorrect syntax near the keyword 'table'.
Msg 137, Level 15, State 2, Procedure fnTest, Line 12
Must declare the scalar variable "@Source_Tbl".
The input table can have several thousand rows.

I need to create an output from a T-SQL query that picks a numeric variable and uses the print function to output with leading zeroes if it is less than three characters long when converted to string. For example if the variable is 12 the output should be 012 and if the variable is 3 the output should be 003.
Presently the syntax I am using is PRINT STR(@CLUSTER,3) . But if @CLUSTER which is numeric is less than three characters I get spaces in front.

I want to run a sql script that creates some views using "osql". The views in turn refer to user defined functions which need a two-part name reference(MyUser.MyFunction). Is there a way to do this without hardcoding the value of the "MyUser" in the script?
Example..
I want to run a script called myscript.sql using OSQL. The file myscript.sql looks like this..
CREATE view V1
AS
SELECT *, UserOwner1.MyFunction1(5)
FROM MyTable
go
CREATE view V11111
AS
SELECT *, UserOwner1.ScalarFunction11111(7)
FROM MyTable
go
-----
I do not want to hardcode the username (UserOwner1) since it varies from database to database. So when I run this script from command prompt using "osql" I want the ability to supply the value for the username (UserOwner1) which owns the user defined function. How to do this?
This problem would go away if SQLServer 2000 was not so adamant about requiring two part reference to a user defined function.
Thanks!

Hello Everybody,
I am sure this has been asked a thousand times before in a thousand different ways, but here goes...
I am in need of the ability to prompt users for a From Date and To Date to insert into a WHERE clause in SQL queries. What is the easiest least painful way of accomplishing this? A great many of our customers utilized SQL Server Express or MSDE, so they do not have the full gambit of SQL tools handy. Believe me when I say that I have searched high and low across the internet for this solution. I was hoping I might be able to accomplish this through VB Script or J Script. Or, anything reasonable.
Thanks in advance for your time and patience,

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)

Hi All
Yesterday Peso was gracious enough to help me with creating function/views/sp's
I took those examples and extended what had from excel into function in SQL
however I see myself repeating certain parts of the query and i'm wondering if there is a way to call a function (in part or in whole) from another function?
Here are excerpts two functions I have:
We'll call this function UserUsage()
------------------------------------
RETURN(
SELECT ut.LastName, ut.FirstName,
CEILING(Sum(hu.session_time)/ 60000) AS [Time Spent(MIN)],
Max(hu.time_stamp) AS [Last Log Date],
pct.Title, cat.topic_name
FROM ZSRIVENDEL.dbo.UserTable ut,
ZSRIVENDEL.dbo.history_usage hu,
ZSRIVENDEL.dbo.pc_CourseTitles pct,
ZSRIVENDEL.dbo.cam_topics cat
WHERE ut.student_id = hu.student_id
AND hu.course_id = pct.CourseID
AND hu.topic_id = cat.topic_id
AND ((ut.ClientID=@ClientID)
AND (pct.ClientID=@ClientID)
AND (ut.GroupID=3400)
AND (hu.time_stamp>= @StartDate
And hu.time_stamp< @EndDate)
AND (hu.session_time<21600000))
GROUP BY ut.LastName, ut.FirstName, pct.Title, cat.topic_name
)
and will call this function UserSummary():
-----------------------------------------
RETURN (
SELECTut.LastName, ut.FirstName,
CEILING(SUM(hu.Session_Time) / 60000.0) AS [Time Spent(MIN)]
FROM ZSRIVENDEL.dbo.UserTable AS ut
INNER JOIN ZSRIVENDEL.dbo.History_Usage AS hu
ON hu.Student_ID = ut.Student_ID
WHERE ut.ClientID = @ClientID
AND ut.GroupID = 3400
AND hu.Time_Stamp >= @StartDate
AND hu.Time_Stamp < @EndDate
AND hu.Session_Time < 21600000
GROUP BY ut.LastName, ut.FirstName
)
As you can see the first part of the both query are simlar. In particular the:
SELECTut.LastName, ut.FirstName,
CEILING(SUM(hu.Session_Time) / 60000.0) AS [Time Spent(MIN)]
and also the variables @StartDate and @EndDate.
In C# it would create a method and just call that method as well as the variables. However i'm not sure how to do that with sql functions. Could someone shed some light please?
Thank you!
