How to Use Sequence Object Inside User-defined Function In SQL Server
I'm trying to call sequence object inside SQL Server user-defined function. I used
Next Value for dbo.mySequence to call the next value for my sequence created. But I'm getting an error like below.
"NEXT VALUE FOR function is not allowed in check constraints, default objects, computed columns, views, user-defined functions, user-defined aggregates, user-defined table types, sub-queries, common table expressions, or derived tables."
Is there any standard way to call sequence inside a function?
I would really appreciate your response.
Thanks!
The NEXT
VALUE FOR function cannot be used for User Defined function. It's one of the limitation.

What are you trying to do? Can you give us an example and required output?

User define function for SQL Server
Hi all,
it's possible to write an UDF for SQL Server in Java?
I know that it is possible with DB2 and Oracle.
My main goal is to write an UDF that works well with all of these DB.
Thank'sHi all,
it's possible to write an UDF for SQL Server in
Java?Okay, JDBC can talk to any database (given you have a driver implementation). Also, JDBC is like a conduit. So the real question is likely, will your database let you do this?
I know that it is possible with DB2 and Oracle.
My main goal is to write an UDF that works well with
all of these DB.I also don't know what a UDF is, but if you ARE talking about stored procedures, then no, it's not possible. All databases are different. On that note, I typically recommend NEVER using stored procedures unless absolutely necessary.
But it also sounds like you want to do this at runtime. I've seen systems that do this (bind stored procs at runtime dynamically) and it's a freakin nightmare! So be careful. -

Using User Defined Function is SQL
Hi
I did the following test to see how expensive it is to use user defined functions in SQL queries, and found that it is really expensive.
Calling SQRT in SQL costs less than calling a dummy function that just returns
the parameter value; this has to do with context switchings, but how can we have
a decent performance compared to Oracle provided functions?
Any comments are welcome, specially regarding the performance of UDF in sql
and for solutions.
create or replace function f(i in number) return number is
begin
return i;
end;
declare
l_start number;
l_elapsed number;
n number;
begin
select to_char(sysdate, 'sssssss')
into l_start
from dual;
for i in 1 .. 20 loop
select max(rownum)
into n
from t_tdz12_a0090;
end loop;
select to_char(sysdate, 'sssssss') - l_start
into l_elapsed
from dual;
dbms_output.put_line('first: '||l_elapsed);
select to_char(sysdate, 'sssssss')
into l_start
from dual;
for i in 1 .. 20 loop
select max(sqrt(rownum))
into n
from t_tdz12_a0090;
end loop;
select to_char(sysdate, 'sssssss') - l_start
into l_elapsed
from dual;
dbms_output.put_line('second: '||l_elapsed);
select to_char(sysdate, 'sssssss')
into l_start
from dual;
for i in 1 .. 20 loop
select max(f(rownum))
into n
from t_tdz12_a0090;
end loop;
select to_char(sysdate, 'sssssss') - l_start
into l_elapsed
from dual;
dbms_output.put_line('third: '||l_elapsed);
end;
Results:
first: 303
second: 1051
third: 1515
Kind regards
TaoufikI find that inline SQL is bad for performance but
good to simplify SQL. I keep thinking that it should
be possible somehow to use a function to improve
performance but have never seen that happen.inline SQL is only bad for performance if the database design (table structure, indexes etc.) is poor or the way the SQL is written is poor.
Context switching between SQL and PL/SQL for a User defined function is definitely a way to slow down performance.
Obviously built-in Oracle functions are going to be quicker than User-defined functions because they are written into the SQL and PL/SQL engines and are optimized for the internals of those engines.
There are a few things you can do to improve function
performance, shaving microseconds off execution time.
Consider using the NOCOPY hints for your parameters
to use pointers instead of copying values. NOCOPY
is a hint rather than a directive so it may or may
not work. Optimize any SQL in the called function.
Don't do anything in loops that does not have to be
done inside a loop.Well, yes, but it's even better to keep all processing in SQL where possible and only resort to PL/SQL when absolutely necessary.
The on-line documentation has suggested that using a
DETERMINISTIC function can improve performance but I
have not been able to demonstrate this and there are
notes in Metalink suggesting that this does not
happen. My experience is that DETERMINISTIC
functions always get executed. There's supposed to
be a feature in 11g that acually caches function
return values.Deterministic functions will work well if used in conjunction with a function based index. That can improve access times when querying data on the function results.
You can use DBMS_PROFILER to get run-time statistics
for each line of your function as it is executed to
help tune it.Or code it as SQL. ;) -

Hi All,
I am trying to use jar files provided to me in user defined function as follows:
DataEncryption temp = new DataEncryption();
String ret = new String();
ret = temp.getEncryptedData(a);
return ret;
All jar files working perfectly in java software, But when i am trying to test the mappings by using above user-defined function.
I am catching the error and put in target field then, I am getting following message in target field:
"An error occured in getEncryptedData method : java.lang.SecurityException: The provider SunJCE may not be signed by a trusted party"
Please help in finding the error.

Check if the XI Server JRE is the same as the client machine on which you have compiled your JAR.

Please let me know if you come across any reference articles related to
Creating a SQL Server table and View with columns as SQL Server TVP similar to Oracle UDT like

"CUST_ADDRESS" "OE"."CUST_ADDRESS_TYP" ,
"PHONE_NUMBERS" "OE"."PHONE_LIST_TYP" ,
"NLS_LANGUAGE" VARCHAR2(3 BYTE),
And also creating a SQL Server TVP inside an another SQL Server TVP as in Oracle
create or replace TYPE customer_typ
AS OBJECT
( customer_id NUMBER(6)

How to export values to a user defined function
Hi Experts,
I want to create a function module under FUNCTION EXIT_SAPMIWO0_020.How to access these values into the called function?
I tried it using IMPORT parameters of the called function.But while debugging I am not getting these values.
Can any1 suggest a solution for this problem?
Regards,
Sam.> Earlier I was using RFC enabled function module for sending the mail under FUNCTION EXIT_SAPMIWO0_020
You were using aRFC (starting new task: it starts immediately and asynchronously), not tRFC (transactional RFC: it starts only at the end of COMMIT WORK).
> and the mail was getting delivered instantly.
It was only because you were using RSCONN01 (preceded by commit of course), not because of the aRFC.
> Here also I am using COMMIT WORK before
> SUBMIT rsconn01 WITH mode = 'INT' AND RETURN.
Well that's very strange it doesn't send the mail immediately! (see my answer below)
Note that it is dangerous (for many reasons I don't need to explain here) to run COMMIT WORK, SUBMIT, and a few other statements, in a BAdI, especially when it's at save time. Prefer to use tRFC as I said (and not the aRFC).
> Also the sent item of the mail in outlook is 50 minutes ahead of our system time
> Is it the reason for a delay in mail delivery?
As you call RSCONN01, the delay can only come from something external to SAP. Check the logs in SCOT, to make sure SAP has sent the mail immediately. In the mail you receive, look at the MIME information in the header of the mail, to check the times at which the mail is transferred from a server to another. Ask your administrator to help you. -
How to use classes from different user defined Packages
well i made 2 packages... one containing employee class and realted matter and other contaning bankaccounts and bank related work... now how can i use them in an another.. i know about the import statement but still couldn't make it work.... now suppose iam makin a obejct of employee class and passing in name and salary and all in the constructor... now i want that when i create the bankaccount class then the name of the employee should be passed to the bankaccount class so that it can assigen a account no. .. now how do i do this as when i create a object of employee class its made at runtime.. and if i create a object of bankaccount.. how wil it take that name as before goin to bank account i should already have a list of emplyees and then this list should be worked upon by the backaccount class to assign the accountno.s
Hope my question was clear... would appriciate a explanation and guidance!!!Thank you so much ... i was able to solve the problem... i passed the object in the constructor of the accounts class and it all worked out the way i wanned... thank you so much... it wasn't that difficult but the idea was just not clicking...this place is wonderful... everyone rocks!!! and so greatful about all the help.. please keep up the good work and even i will try to contribute as much as possible!!

Where are User Defined Functions and Stored Procedures kept in SQL Server?
Hi,
I have a growing list of Stored Procedures and User-Defined Functions in SQL Server, and would like to be able to list all my user SP and UDF easily.
Is it possible to write a query to list all SP and UDF?
I saw the following specimen code in an SQL book, but am not sure this is what I need because I could not make it work.
SELECT *
FROM INFORMATION_SCHEMA.ROUTINES
WHERE SPECIFIC_SCHEMA = N'CustomerDetails'
AND SPECIFIC_NAME = N'apf_CusBalances'
I tried:
SELECT *
FROM INFORMATION_SCHEMA.ROUTINES
but it does not work.
Suppose all my SP are named following this pattern:
dbo.usp_Storeproc1
How would I modify the above code? or is there a better code?
Thanks
Leon LaiHi ,
try this to get list of all stored procedures:
SELECT *
FROM sys.procedures where name like 'dbo.usp%'

Using a SQL user-defined function in Crystal Reports XI
Post Author: JoannKarp
CA Forum: Formula
Is it possible to use a user defined function in SQL and use this in multiple Crystal reports?
JoannKarpSELECT COALESCE(ufn_GetAddressByBusinessEntityIDandAddressTypeID(table1.BusinessEntityID,712),ufn_GetAddressByBusinessEntityIDandAddressTypeID(table1.BusinessEntityID,712)) AS Zipcode
FROM table1
Nope. This is two function calls. coalesce(a, b, c, ...) is just syntatic sugar for
CASE WHEN a IS NOT NULL THEN a
WHEN b IS NOT NULL THEN b
WHEN c IS NOT NULL THEN c
END
But if you use isnull it's a different matter. (But isnull() permits two arguments.)

? Regarding 'SQL user-defined function' execution performance ?
Hi All,
I have an user-defined function in SQL which am using in a SQL select statement and i found that the execution time taken by the user-defined function is 9-10 minutes as a result of which my whole query execution time is affected.
How to i improvise the execution time. Should i do some sort of scheduling for executing the user-defined functions only. Am new to the database world. Your early response with a good suggestion would really be appreciated.
Thanks in Advance.Try to read SQL tuning documents along with TkProf. Then only you will be able to detect the problem.
There is no instant method by which you can solve this problem.
But, you can get idea from this samples.
