SQL & PL/SQL :: Does Oracle Log Exception In User Defined Function

Jan 12, 2012

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;

SQL & PL/SQL :: User Defined Type

Jun 19, 2012

I 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.

User Defined Data Type

Jun 19, 2012

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);

How To Use User Defined Type While Creating New Table

Oct 13, 2009

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:

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.

Possible To Easily Set Up A Single User Defined Metric

Dec 28, 2010

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.

SQL & PL/SQL :: User-defined Aggregate Calculation For Z Score

Jun 29, 2011

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);

[Code] .....

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.

PL/SQL :: How To Copy A User Defined Type From Other Schema

Aug 25, 2012

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.

SQL & PL/SQL :: User Defined Data Types In Cast Functions

Jun 22, 2010

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.

Precompilers, OCI & OCCI :: Retrieve Collection Of User-defined Object?

May 9, 2003

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

The major steps I am using are
1. define database object

CREATE OR REPLACE TYPE my_obj_t AS OBJECT
( id number, name varchar2(10) )
CREATE OR REPLACE
TYPE my_obj_tab_t as table of my_obj_t;

2. A stored procedure return a collection as out paramerter
my_stored_procedure(obj_list out my_obj_tab_t);

3. Using OTT to generate the *.cpp and header files.

4. Register out parameter like
vector<my_obj_t> vect;
stmt->registerOutParam(1, OCCIVECTOR,
sizeof (vect),
"MY_OBJ_TAB_T");

5. stmt->execute();

6. Try to get the results by
getVector(stmt, 1, vect);

I am getting compilation error:

Could not find a match for
oracle::occi::getVector(oracle::occi::Statement*,
int, std::vector<my_obj_t, std::allocator<my_obj_t>>).

Am I doing the right things ?What steps and function should I use ?

Application Express :: Exception Handling Pl Packages And APEX Exception Handler

Oct 7, 2013

APEX 4.2Oracle 11g Database We are using the standard exception handler that was introduced in APEX 4.1, and we have code in packages & procedures in the database (following proper processes of keeping code in the database where possible).  When an exception is found in the procedures/ packages/functions, should the APEX application level exception handler catch any errors that occur or should they be handled in the package/procedure/function they occurred in? Why I ask if, we right now have exception handling code in the pl/code bodies BUT they write their errors to the same table that Apex's Exception handler does, but the errors are NOT presented to the user using the APEX exception handling mechanism.

ORA_JAVA.CLEAR_EXCEPTION;

when ORA_JAVA.EXCEPTION_THROWN then
ex := ORA_JAVA.LAST_EXCEPTION;

-- lv_exception := Exception_.getMessage(ex);

I get an error for the line: 'message( Exception_.toString(ex));'I have imported the java classes FException et IObject with their methods.

I have to create a Web Service Client, so I wonder if the paragraph Quote:when ORA_JAVA.EXCEPTION_THROWN then ex := ORA_ JAVA. LAST_ EXCEPTION; is mandatory.
