MS SQL Server :: Function To Call Function By Name Given As Parameter

Using A Scalar Valued Function As A Parameter Of A Table Valued Function?
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)

Need Help Understanding A Call To A Sql Function
Can someone help me to understand a stored procedure I am learning about? At line 12 below, the code is calling a function named"ttg_sfGroupsByPartyId" I ran the function manually and it returns several rows/records from the query. So I am wondering? does a call to the function return a temporary table? And if so, is the temporary table named PartyId? If so, the logic seems strange to me because earlier they are using the name PartyId as a variable name that is passed in.

1 ALTER PROCEDURE [dbo].[GetPortalSettings]2 (3 @PartyId uniqueidentifier,45 AS6 SET NOCOUNT ON7 CREATE TABLE #Groups8 (PartyId uniqueidentifier)910 /* Cache list of groups user belongs in */11 INSERT INTO #Groups (PartyId)12 SELECT PartyId FROM ttg_sfGroupsByPartyId(@PartyId)

Call Custom SQL Function In ASP.NET

When I call this SQL function in VS2005, it says it does not recognize the function. Does anyone know what this may cause? thank you. For the people who are bored, I added the SQL statement. The error is at the function

Call Function From Stored Procedure

I'll admit that I'm not the greatest at stored procedure/functions but I want to learn as much as possible. So I have two questions:

When Updating a record and calling the stored procedure, I want to query another table (we'll call it tblBatchNo) that has only one record, Batchno. I want to put that current batchno into the Update statement and update the record with the current batchno. Can someone point me in the right direction? Remember that I'm still a beginner on this subject.
2) Can someone provide any links to online tutorials on t-sql?

Function Call In Dataset Query
Hello Guys,

I have a question that seems easy but I can not figure out...

Premise:

Have Custom code that fixes Divide by Zero Errors in SSRS. I have added the code to the Custom Code area in Report Properties correctly.

I have a Dataset that has a calculation for a column within a select statement

Query Pseudocode:

select ...[FRC%]=convert(decimal(13,2),sum(cost))/convert(decimal(13,2),sum(income))...
,year
from

(subquery"blah" )

Union

(Subquery"blah")

Custom Code:

Public Function SafeDiv(ByVal numerator as Double, ByVal denominator as Double) as Double
    if denominator = 0 then
        return 0
    else
        return numerator/denominator
    end if
End Function

How To use:

If you have a field that does division and you need to eliminate the divide by zero error that occurs with SSRS then type =code.SafeDiv(first,second) in the field.

Problem:

How do I add this code reference in the following dataset select statement

select ...[FRC%]=convert(decimal(13,2),sum(cost))/convert(decimal(13,2),sum(income))...
,year
from

(subquery"blah" )

Union

(Subquery"blah") table1

I tried to do this:

from this:

[FRC%]=convert(decimal(13,2),sum(cost))/convert(decimal(13,2),sum(income)) ...

to this

[FRC%]=code.Safediv(convert(decimal(13,2),sum(cost)),convert(decimal(13,2),sum(income))) ...

But it did not work...gave me this error:

TITLE: Microsoft Report Designer
------------------------------

An error occurred while executing the query.
Cannot find either column "code" or the user-defined function or aggregate "code.safediv", or the name is ambiguous.

Problem With Nested Function Call (UDFs)
Hello Folks,I encountered a problem with SQL server 2000 and UDFs.I have a scalar UDF and a table UDF where I would like the scalar UDFto provide the argument for the table UDF like in:SELECT*FROMtransaction_tWHEREtrxn_gu_id in (select get_trxns_for_quarter(get_current_quarter( GetDate() ) ))'get_current_quarter' returns an integer which is a GUID in a tablecontaining business quarter definitions, like start date, end date.'get_current_quarter' is a scalar UDF.'get_trxns_for_quarter' will then get all transctions that fall intothat quarter and return their GUID's in a table.'get_trxns_for_quarter' is a table UDF.This doesn't seem to work at all. Regardless whether I provide thenamespace (schema) calling the scalar UDF or not. Error message isjust different.Both functions operate correctly invoked un-nested.The whole expression does work fine if I turn 'get_trxns_for_quarter'into a scalar UDF as well, e.g. by returning just one trxn_gu_id withe.g. MAX() in a scalar datatype. But of course that's no good to me.It also works fine if I select the result of 'get_current_quarter'into a variable and pass that variable into 'get_trxns_for_quarter'.But that's no good to me either since then I cannot use the wholething embedded into other SELECT clauses.Both UDF's are non-deterministic but I couldnt see how that would havean impact anyway.Never mind the syntax on that example or anyhting, I tried all theobvious and not so obvious stuff and it really seems to come down tothe fact that one UDF is scalar and the other one is not. However, Idid not come across any type of information saying that this cannot bedone.Have you any ideas?Any help would be greatly appreciated.Carsten

Is Possible To Call A VB.NET Function Within Derived Transformation Editor
Hi,

In a nut shell I want to be able to instruction some Data Analysts on how to modify SSIS packages using the simpliest solutions possible. This is because there are many different data sources and some of these data sources have a huge number of fields, and yes you guessed it these data sources are subject to change on a regular basis.

A very common task they will need to do is to modify an SSIS package to do a to transform of a source date string format of "YYYYMMDD" into a date data type field within a table.

Similar threads have advised the use of the Data Flow Transformations->Derived Column for this sort of thing.

So within the Expression Text box I have inserted the following SSIS compatible SQL to convert the above string into a british format date data type; -

Code Snippet
(SUBSTRING(DOB_SRC,8,2) + "/" + SUBSTRING(DOB_SRC,5,2) + "/" + SUBSTRING(DOB_SRC,1,4))

But really what I want to be able to do is to instruct the Data Analysts to do is something like; -

ConvertTextToDate(DOB_SRC)

Where I previously defined that behaviour of ConvertTextToDate as a public VB.NET function.

Can someone please help. I'm pretty certain I'm not the only one with this type of requirement.

Thanks in advance,

Kieran.

Can I Apply A Database Function Or Assembly Call In An Expression For Filter Data?
I need to translate a user€™s regional setting into one of our own language codes before I send it through as a filter to the model query. If our language codes were the same, the filter would look like this in the report filter -
                     Language Code = GetUserCulture()
Which translates to this in the database query (for us english) -
                        table.language_code = 'EN-us'
And of course I need it to look like this -
                             table.language_code = 'ENG'

I would like the logic to be globally available to all report writers (ie not forcing each report writer to have an iif or case stataement). I was thinking custom assemblies or maybe a database function, but at this level of the filter, I cannot seem to figure out how to embed a database function call to apply to the filter criteria like this
              Language Code = dbo.ConvertFcnIWrote(GetUserCulture())
Or how I would access the custom assembly in the filter expression.

Do you have a recommended implementation for this situation?

SELECT     Year_Key, Year_Name, Year_Short_Name, Year_Number, Year_Start_Date, Year_End_Date
FROM         d_Time_School_Year
WHERE     (Year_Key = ?)

This works fine. But I want to pass the year_key to a function which accepts a parameter. The SQL should be like this

SELECT     Year_Key, Year_Name, Year_Short_Name, Year_Number, Year_Start_Date, Year_End_Date
FROM        fn_TimeDimension (?)

But SSIS doesn't like this. When I click on parameters command button I get and error like this

"Parameters cannot be extracted from the SQL command. The provider might not help.........

Syntax error, Permission Violation, or the non-specific error(Microsoft SQL native Client)"

Any clue how to utilize the variables in a SQL which gets data from a function instead of a table?

Thanks

Can't Use Parameter With DateAdd Function??
Hi, I encountered a strange error today. I have an Integer parameter "hours" that I am trying to use in my SQL Query.

DATEADD(hh, @hours, @startTime)

It works if I have it set such as DATEADD(hh, 8, @startTime), but I need that parameter there for what I need.

I get this error:

Error Source: System.Data
Error Message: Failed to convert parameter value from Decimal to DateTime. I tried a variety of CInt and other conversion functions to no avail.

Any ideas?

Multi-value Parameter And Function
I have a report with the following dataset query:

Code Snippet
SELECT    ...,
       dbo.getActivitySinceBeginningYear(..., @countryId ,...) AS HoursYear
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)
set @return = 0.0

SELECT @return = SUM(detail.HOURS_WORKED)
FROM ...
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
WHERE cast(detail.COUNTRY_ID as nvarchar(max)) IN (@countryId)

If I do:

Code SnippetWHERE detail.COUNTRY_ID IN (@countryId)

I have the following error:
Conversion failed when converting the nvarchar value '3,5' to data type int.
(I transmitted 3 and 5 for countryId)

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

Using A Cursor As A Function Parameter

I've created a function that converts the rows of a column into a delimited string using a passed cursor and delimiter character. In the past I did this in Oracle and called it as shown in the following example:

SELECT Table1.ID, Table1.FirstName, Table1.LastName, fnDelimitRows(CURSOR(SELECT Table2.CourseName FROM Table2 WHERE Table2.StudentID = Table1.ID), ',') AS AssignedCourses FROM Table1

23 John Smith CS101,MT200,BIO100
43 Julio Johnson CS200,ENG100,MT300

How would I pass a cursor into a function in SS like I did above in Oracle?

Thanks!
