I have made a function to add two number create or replace function add_num(a in number, b in number) return number
as
begin
return a+b;
end;
/
i run it via
select add_num(2,5) from dual;
my question is how to call add_num in procedure.
If a user defined function in Oracle may throw and catch exceptions depending on input, now does the Oracle logs the exception? Fundamentally we are asking if Oracle logs any random DML errors (not bulk operation). We hope not, as we do not want our client DBA get concerned. There might be many levels of settings in Oracle to log or not log. So if Oracle may log it depending on setting, how do we suppress it either at Oracle specific schema level, or function level?
This is my user defined function:
create or replace FUNCTION ISNUMERIC(char_in CHAR) RETURN NUMBER IS
n NUMBER ;
BEGIN
n := TO_NUMBER(char_in);
RETURN 1;
EXCEPTION
WHEN OTHERS THEN
RETURN 0;
END;
In one of the interviews , I have attended the guy asked me to write a user defined function which will take the column name and list all the values .
For example
Table Name:Employees
Column Name: Employee_Name
Employee_name
Scott
Ivgun
Jack
Shane
The query should be in this fromat
SELECT col_agg(Employee_name) emp_name from Employees;
The output should be
Emp_names
scott,ivgun,jack,shane
can i create the user-defined functions and use them in the FILTER clause in the sem_match function? there are some built-in functions for the FILTER clasue. however, only one function (DATATYPE(literal)) support for date/time in the built-in functions. i want to implement some user-defined funcitons in the FILTER clause which can check time intervals in ontology. there are some functions about valid time in the WorkSpace Manager such as WM_OVERLAPS, WM_CONTAINS,WM_MEETS, etc. so, can i write some functions using the these valid time functions in WM and use them in the FILTER clause?

View 5 Replies View RelatedI am trying to create a new data type but keeping getting a ORA-0902 invalid data type error. I am using the example show at:
Guess I cannot post a link until I have posted more than 5 messages so here is the link another way:
www(dot)psoug.org/reference/type.html
Specifically, all the steps work up to Create Table which fails with the error.
By work -- I mean the type gets created & the 3 select statements prior to Create Table confirm the existence of the ssn_t data type.
I am trying to create & use a new data type but keep getting a ora-0902 invalid data type error running on 10g express. The create type and select statements execute fine and select confirms the ssn_t is a type. The create table statement fails with the invalid data type error.
Here is an example.
CREATE TYPE ssn_t AS OBJECT ssn_type CHAR(11));
SELECT object_name, object_type
FROM user_objects WHERE object_type = 'TYPE';
CREATE TABLE Z (A CHAR(4), B SSN_T);
That is I have created the User Defined Data Type as following. CREATE OR REPLACE TYPE Bit_Type AS OBJECT(Bit NUMBER(1,0));
After completing this creation of new UDT, I am trying to create the table with this UDT as follows, CREATE OR REPLACE TABLE Sample_Bit ( RegID Bit_Type);
I received an Error Message like:
SQL Error: ORA-22913: must specify table name for nested table column or attribute
22913. 00000 - "must specify table name for nested table column or attribute"
*Cause: The storage clause is not specified for a nested table column or attribute.
*Action: Specify the nested table storage clause for the nested table column or attribute.
Is it possible to easily set up a single User Defined Metric, to monitor all the users quotas? I know I can do it, if I make individual metrics for each user. But was hoping there was a simple way of combining them all into a single metric.
I am using Oracle 10G2 Standard Edition on a windows 2003 Server.
I'm calculating a Z score based on some simple numerical data thus:
create table t (id number, val number);
insert into t values(1, 1795);
insert into t values(2, 1753);
insert into t values(3, 1743);
insert into t values(4, 1876);
insert into t values(5, 1848);

the logic is quite simple - calculate a moving average over the previous 12 rows, and a stdev over the same window. Then subtract the prior row's moving average from the current value, and divide by the prior row's stdev.
The issue is I want to expose this logic in a BI tool (OBI EE v10g), meaning I can't use the nested analytic functions. How to achieve this logic in a single analytic pass? The sql above took about 2 minutes to write this morning, then I've spent all day looking at user-defined aggregate functions, but haven't even been able to get the first step, the moving average, working. I can understand that I can probably create an udaf to replicate the avg(val) over (order by id ROWS BETWEEN 11 PRECEDING AND 0 FOLLOWING) functionality, but I can't see how to bundle the logic for the other three steps in the calculation into this.
From what I've read, the ODCIAggregateMerge should allow me to combine different threads that can return the different values I need for the current row calculation. Is this correct?
The only example udafs I can find are either not relevant (STRAGG) or very simple (ie don't appear to invoke multiple passes). I've also had a look at the COLLECT function, but again I can't see a way to use this.
I have designed a Login form which takes username, password and connect string is hardcoded.I have compiled it, made an fmx file. created a shortcut to desktop. given the BIN path in shortcut.
when i want to lauch it, oracle's default login popup is shown.It can be by passed while defining username/password@string in shortcut properties but it reveals the password. every one can access it. I want to launch my own form without logging in to oracle. how can i avoid default login popup?
Can we able to declare a user define exception name as per defined exception name?Ex: we have predefined exception called :"NO_DATA_FOUND "

Through sql*plus, how can I copy a user-defined type from other schema to mine?
I've granted the execute object privilege over the user-defined type to my user, so I can use the type.
I know I can manually write and create the type, but I wanna learn (if exist) a statement to copy the user-defined type, something like:
CREATE TABLE x2 AS
(SELECT *
FROM x1);
I'm testing ORACLE DATABASE 11g R2 over Windows O. S.
I am migrating sybase to oracle database. A Java developer needs money datatypes.I said to them, please change the cast(<value> as number(19,4) in java code side. but they are not accepted because money data type is used most of the places.
select cast(0 as money) from bank_trans; this sql statements present in java code. I need to create user defined type is equivalent to money datatype.
My steps
I have create user defined data types
create or replace type money as object(money as numbeer(19,4)
select cast(0 as money) from dual;
it shows inconsistent datatypes error.
create or replace type money is table of numbeer(19,4);
select cast(0 as money) from dual;
it shows inconsistent datatypes error.

View 1 Replies View RelatedI am having a OCCI problem, I try to retrieve a collection of user-define objects.

CREATE OR REPLACE

I am defining a function in a schema as a user with admin role (default). The function is to do a call to another function on a custom package in SYS schema.
something funny happens : when I compile the function (defined with authid as DEFINER)it says that the function SYS.custom_package.myFunction is not defined.
however if I do a select sys.custom_package.my Function from dual it's okay.
why this behaviour and how to work around it? You see, the package in SYS proposes a number of other functions that I don't want to expose. I only intend to create some sort of wrapper function that would Marshall the call to the my Function only on the custom_package in SYS.
my wrapper function looks something like that :
create or replace function myFunction_wrapper authid definer return pls_integer is
begin
return sys.custom_package.myFunction;
end;
i am trying to call a function from Sql statement and i am getting this error ORA-06572: Function XX has out arguments.
