PL/SQL :: Oracle 11g Table Function Returns No Records On First Call?
Jul 13, 2012
On a Oracle 11g R2 I've a table function ( PIPELINED ) returning rows selected from a table.The first time the function is selected, in a session ( I've tried to disconnect and log in again ), it returns no rows.I've tried to log the call using DBMS_OUTPUT and from what I see the select on the table function returns no rows and no output is printed. So I presume Oracle is not calling the function.
The same function on a similar environment ( same db versions, patches and database structure ) works fine. The second environment is a production environment so it has more memory and some other settings enabled.

CREATE OR REPLACE TYPE TEST_OBJ_TYPE IS OBJECT
(
TEST_ID NUMBER(9),
TEST_DESC VARCHAR(30)
)
/
CREATE OR REPLACE TYPE TEST_TABTYPE AS TABLE OF TEST_OBJ_TYPE

[code]....
I need to include the above function in a plsql package. How I can declare a object type and table type in a pks file? the syntax to include the above code in a .pks and .pkb file?
I got this code snippet online when I was looking for function that returns a table type. what exactly that Exception block does? delete the table when there is an exception, otherwise return the table type?

I am attempting to port some Pro*C code from Tru64 to AIX 6.1.I have compiled the PRO*C into an executable which is then called as follows:
host$ CJSPC004 /@WHDA 19/11/2012
Starting module : CJSPC004
Connected to the database
Running database procedure cjspk003.p_create_job_schedule
Module CJSPC004 completed successfully
However, when querying $? to get the status of the last command I get a non-zero code even though everything has worked.
host$ echo $?
39
On Tru64 this works fine with the echo $? returning a zero as expected:
host$ echo $?
0
The PRO*C was compiled using gcc

How to call a function with a row type return in an Oracle select statement.
For e.g. :
If I had this function with a rowtype return:
------------------------------
create function abc
return xyz%rowtype
is
rec xyz%rowtype;
begin
select * into rec from xyz where col1 = n;
return rec;
end;
--------------------------------
How could I use this in a select clause, as there is a multi column return by the function ?

I have an existing database with several hundred tables and triggers on the tables in the schema S1. Most of the triggers are for storing audit information USER and SYSDATE in the respective columns.
We have built procedures what will accept incoming XML parameters from a BPMS application on the intranet which will have information about which table to update, which columns to update, what values to update and what the O/S user id is. The O/S user ids are mapped to oracle user ids in a specific table. Therefore when we receive the request we can easily figure out the oracle user id. The application always connects to the database using a specified user id S2.
The trouble is, the existing tables have triggers which read :NEW.userid := USER;and whenever a DML is fired from the procedure, the function USER always returns S2, since that is the user id the BPMS application connects to and therefore the audit columns do not capture the correct information as required.
The impact of changing all the existing triggers/procedures will be a mammoth task including regression testing and will certainly not be approved by the project sponsor.
override the value that USER returns? Using session contexts, etc? If so, we can possibly set it at the point of connect and have to do nothing else.

I am interested if there maybe exists any function that would return all source tables that are present in the given sql. For example function('select 'abc' from table_1, table2') would return a list containing 'table_1' and 'table_2'.

I have an requirement to create an function which takes table or hierarchy of tables as input and returns xml output in hierarchy. Below given is the Tables hierarchy.
AAAA
----AAA
----BBB
----CCC
-------CC1
-------CC2
-------CC3
[code]....
Requirement: Initially input was table name and using table as the root node output should generate xml of all the records of child tables.But now requirement is to give the flexibility to user to select what hierarchy he needs i.e he may select AAAA, CCC and in the nodes C1,C2,C3 and C4 if he doesn't want C3 then that node should not be shown in output.
I have created Hierarchy table having 3 columns SI.No, ParentNode and ChildNode and entered the above hierarchy relation.
1. What is the best to way (design)to pass input parameter for the function.
2. How to generate hierarchy in xml using DBMS_XMLGEN

The SAMPLE clause in the select statement works well in most cases, but we found in some instances the result is way off - between 200% to 700% discrepancy has been observed.
For example, we have thee tables with the following results:
Table1: 495,365,317 rows (20 cols, unique primary key present), SAMPLE ( 0.002018712182064212 ) returns 41,499 (about four times off - we expected about 10,000)
Table2: 3,350,864,539 rows ( 5 cols, unique primary key present), SAMPLE ( 0.00029843044634040336 ) returns 9,835 (this is good as it is close to 10,000)
Table3: 6,974,724,543 rows ( 5 cols, no unique primary key present), SAMPLE ( 0.00014337483779250091 ) returns 58,789 (about six times off - we expected about 10,000)
The tables got billions of rows, and that is why we want to do sampling. The sample percentage rate is computed to return about 10,000 rows in all three tables.On Table3, we ran the sampling three times in one occasion, and we got "58,570", "24,575" and "24,561"
I expected +/- 20% of variance, but 200% to 700% seems to be way too much.Once again, I stress that it does work well in most cases (another 3.4 billion table and numerous smaller tables we tested were well within +/- 5 percent of the target).I noted the presence of a primary key above because I read an article saying that the SAMPLE function relies on the existence of a primary key (which does not quite explain the examples above).Is this kind of spread something we should expect or is it a bug? Is the sampling rate too small for such large tables?

I am trying to update records in the target table based on the records coming in from source. For instance, if the incoming record is present in the target table I would update them in the target else I would simply insert. I have over one million records in my source while my target has 46 million records. The target table is partitioned based on calendar key. I implement this whole logic using Informatica. Looking at the informatica session log I find that the informatica code is perfectly fine but its in the update part it takes long time (more than 5 days to update one million records). find the TARGET TABLE query and the UPDATE query as below.
TARGET TABLE:
CREATE TABLE OPERATIONS.DENIAL_REGRET_FACT
(
CALENDAR_KEY INTEGER NOT NULL,
DAY_TIME_KEY INTEGER NOT NULL,
SITE_KEY NUMBER NOT NULL,
RESERVATION_AGENT_KEY INTEGER NOT NULL,
LOSS_CODE VARCHAR2(30) NOT NULL,
PROP_ID VARCHAR2(5) NOT NULL,
[code].....

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 have a package includes 22 functions, each function just returns a sql template (clob type).
I also have a stored procedure called query_builder, query_builder has applicationName and statementName as parameters. I need to call these functions in the package based on the given applicationname and statementname.
CREATE OR REPLACE PROCEDURE Query_builder (ApplicationName varchar2, StatementName varchar2) IS
SQLSkeleton varchar2;
BEGIN
PackageName := ApplicationName||'_SKELETON;
SQLSkeleton := PackageName.StatementName; -- I know this will not work, but how can i call these function dynamically?

I made this script but I still don't quite understand if the syntax is correct. I just wanted to create a function and call it in an anonymous block. I then wanted it to use a variable as a parameter in an iteration and output the variable every iteration. It's done basically but I know it's not 100% right. The fibonacci function looks like its going to loop an infinite number of times if the parameter is greater than 2.
CREATE OR REPLACE PACKAGE myPACKAGE AS
CREATE OR REPLACE FUNCTION fibonacci
(n BINARY_DOUBLE) RETURN BINARY_DOUBLE IS
BEGIN
IF n <= 2 THEN
RETURN 1;

why function does no raise error no_data found when call in select statement.
1) create one function.
CREATE OR REPLACE function fn_sal(v_id NUMBER) RETURN NUMBER
IS
v_sal NUMBER;
BEGIN
SELECT sal INTO v_sal FROM emp where empno=0;
RETURN v_sal;
END;
2) call it in select statement.
SELECT fn_sal(e.sal),e.* FROM emp e
select satement cause no error , it displayes all the records but null for the function cloumn.
why it not gives no_data_found error.
