We are trying to use the methods/constructors in the object types and find it more similar to the procedures and functions in the packages. I am wondering how they are different from stored procs and functions and what are the advantages?
View 2 RepliesI 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.
I need to transfer PL/SQL or NESTED table from LOCAL database to REMOTE.I need to be able to use that transfered table in SELECT statement.I tried:

create or replace type varchar_number_oid OID '966D2DFEAEEB80D6E0430A0166CB80D6' as object (

I tried using PL/SQL types it worked, but then i have a problem that i can not use local collection in SQL.
I come from a Microsoft SQL background and am having trouble adjusting to the PL/SQL syntax. I'd like to build this up to pass back a certain value back into a web form.

View 5 Replies View RelatedLet us say there is an oracle table A. How do i find out what stored procedures/packages/views are using this table A.
Reason to know: When some DDL changes happen on table A, how do i know what are the impacted sp/pkg/views which should also be modified. Is there any query with which i can find this?
I have to run queries on a gov't computer. There are errors in some of the stored procedures that will NEVER go away. Fact of life, and I have to live with it (I'm just a data analyst--not the developer of the procedures)So I do this, in the hope of trapping the error
BEGIN
run_stored_proc (my_cursor, my_id, param3);
EXCEPTION
WHEN OTHERS THEN DBMS_OUTPUT.PUT_LINE ('ERROR IN ID (' || my_id || '). The error was ' || SQLCODE || ' -ERROR- ' ||SQLERRM);
END;Well, it can still crash.
SQL> @c:mysql
un_test
ERROR IN ID (2692). The error was -20100 -ERROR- ORA-20100: Exception occurred in some_other_stored_procedure
ORA-01422: exact fetch returns more than requested number of rowsSo it looks like run_stored_proc calls some_other_stored_procedure which is having issues. I was hoping that by trying to capture the error in the top level procedure, it would also capture the error in a lower-level "sub-procedure". This is the way a TRY-CATCH in java works. If an error happens anywhere along the way inside the TRY-CATCH, it is caught. Sure, PL/SQL ins't java, but is there a way for me to catch a lower level error and not have this code crash?
Fortunately for me, it actually doesn't crash that often. But I have to put this code in a loop, and run it for many different my_id's. And when it does crash, it isn't significant from a data analysis standpoint. I can't do without a small percentage of the data. But I'd love to be able to just run my script and not have to watch it for unexpected crashes.

View 3 Replies View RelatedWhy do stored procedures and functions improve performance?
A. They reduce network round trips.
B. They reduce the number of calls to the database and decrease network traffic by bundling commands.
C. They reduce the number of calls to the database and decrease network traffic by using the local PL/SQL engine.
D. They allow the application to perform high-speed processing locally.
E. They postpone PL/SQL parsing until run time.
I think the answer should be A and B but i came across answers as B and E Can u explain me what is the difference between option A and B and does it postpone parsing till run time?
Am using Oracle 9i and developing stored procedures in SQL Developer. Have a situation where one stored procedure A is calling another B. Stored proc B builds the SQL based on parameters passed in. For one of the parameters i would like to use a bind variable in the SQL that proc B builds. The bind var is passed back to proc A as a part of the SQL string. In proc A, i then try to bind that variable to a parameter(value), however, the bind does not seeem to work.
The SQL string contained in v_SQLStatement defined as VARCHAR(4000) that is passed back to proc A looks like:
SELECT em.event_title AS event_name,
e.start_date AS start_date,
e.end_date AS end_date
FROM d_event_ml em
inner join d_event e
ON em.event_id = e.event_id
WHERE em.language_id = 46
AND e.end_date >= SYSDATE
AND e.stream_id IN ( :v_x1 )
AND e.event_id IN (SELECT event_id
FROM d_events_seas
[code]....
and o_EventList is defined as REF CURSOR. i'm experiencing is that :v_x1 stays as :v_x1 and does not change.This is my first attempt at using bind vars. URL....

I'm using an existing stored procedure in my C code. The stored procedure in question has been compiled and is proven to work without any errors. However, when I use the same in my C code, its failing with the above error.

View 2 Replies View RelatedHow I could pass list of arguments passed to a pl/sql block in a generic way without knowing their names in advance? I mean that in machine languages you could just get the stack dumped. In PERL you would access @_.In Oracle I could use AWR to extract values bound to a query using system views but what about PL/SQL code?
Let say that I have abstract method:

procedure p(...) is

Actually the our database performance is currently satisfactory, except for occasional few minutes spikes of CPU highs > 80 .I just want to catch the culprit process/program responsible for this spikes. Is it wise to run ASH, AWR, ADDM with an input from time 1AM to 1AM next day? What I mean is I will analyze a 1-day period, so that I can catch the program/process that has the higest cpu/memory usage for the day.

what are the main points that these examples are considered cursors? and why are they called explicit and implicit cursor.
explicit
for x in (select * from emp) loop
dbms_output.put_line('emp no: '||x.empno);
end loop;
implicit
select empno
into vEmpno
from empno
where empname = 'SCOTT';
for all we know that these are not clearly defined on the declaration area as cursor.
we get daily a full dump from our customer. We have to build the differences of tables (deltas) and load them in separate tables.
There some questions, requiremenst and restrictions:
1) Is it possible the merge the dumps ?
2) How to build the differences as the easiest ?
3) The whole process (import, merge, extract) should be run in batch.
4) We have only a solid knowledge and liitle time for doing.
