I have question in procedure execution and function execution oracle database. I want know that which is faster in execution procedure or function. Can i see the time taken by procedure and select query only time.

how can i prove it through examples. can i see the explain plan for a procedure and a function or is there any way to prove which one is faster in execution.
I have a very big oracle procedure. Since it's too big and calling many other procedures, I am not able to debug the exceptions thrown. Any oracle utility which logs all the procedures called by the master procedure step by step and maintains a detailed record.

I am using Oracle 9i.
When the procedure is executing can we drop a procedure . Is there any way to drop the procedure with force .
View 5 Replies View RelatedMy need is to check whether procedure execution is successful and write sysdate and procedure name into log table.
Sure I can check target table which procedure uses to write result and count lines after execution. But I've got different procedures, some of them can write 0 lines and it's not error. I think Oracle should have something like return codes and some number means "ok".
Oracle Version is 11g.
I need to call the same procedure with different parameter multiple time in parallel.
I have job_control Table
CREATE TABLE JOB_CONTROL
(
JOB_CONTROL_ID NUMBER NOT NULL,
JOB_SEQ_NO NUMBER NOT NULL,
MODULE_NAME VARCHAR2(32 BYTE) NOT NULL,
JOB_STATUS VARCHAR2(15 BYTE),
NO_OF_RECORDS NUMBER,
PROCESSED_RECORDS NUMBER
);
Insert into JOB_CONTROL
(JOB_CONTROL_ID, JOB_SEQ_NO, MODULE_NAME, JOB_STATUS, NO_OF_RECORDS)
Values
(20, 1, 'SALES', NULL, 5);
Insert into JOB_CONTROL
[code]........
Now the table look like this.

based on the data available in table i wanted to execute a procedure 6 times
create table job_table
(now date, seq_no number)
the procedure will have one parameter as job_seq_no
create of replace procedure job_call (i_job_seq_no number)
is
begin
for i in 1.. i_job_seq_no
loop
insert into job_table
values
[code]......
the problem is i want to do this activity in parallel , i.e. all six calls to the procedure would be parallel. and this will be one time activity.
I created the following stored procedure which I am calling from a script. I compiled my Stored Procedure with Debug Info. For some reason Execution jumps from the second BEGIN to the END statement.
Since the SP compiles w/o any errors, I suspect I have a logic error.
Stored Procedure:
CREATE OR REPLACE PROCEDURE VALIDATE_PATIENT_NEW
(
VALIDATED OUT int,
LAST_NAME IN VARCHAR2 DEFAULT NULL,
FIRST_NAME IN VARCHAR2 DEFAULT NULL,
DOB date DEFAULT NULL,
PAT_NUMBER OUT int,
FACILITY_KEY OUT CHAR
)
AS
BEGIN
/* SELECT * */
BEGIN

Is there any way of returning output parameter values to calling environment before completion of procedure execution. I may achieve it by using GTTs, looking for any other way (because calling environment again need to issue select statement to retrieve data from GTT).
Example case:
Procedure have multiple ref cursors as out parameters.
....
...
if exp1=exp2
then
open v_ref_var1 for select ...from ... ;
end;
[code]..........
If the first if condition satisfies, ref cursor - v_ref_var1 data should be immediately available for the calling environment.
I have a procedure which i wrapped using the oracle 11g wrap utility. If i execute the wrapped procedure using jdbc i am getting an error of 0RA-00900 invalid sql statement.
The procedure is having basic sql statements only.The same procedure if i wrap using Oracle 9i and execute using jdbc it works fine.Is there any change in Oracle 9i wrap utility and Oracle 11g wrap utility.
I tried even Oracle 10g wrap it is also not working fine.
I am currently studying a Foundation degree in computer software development, and one of my assignment in PL/SQL I am stuck on one of the tasks.
I have to create a procedure where one of the parameters needs to have a default value of one, if no value is entered when the procedure is called. I have trued to use the NVL function which worked when using a anonymous block, but now I have to convert that to a procedure. My problem is I'm getting an error.
The code for the procedure is
CREATE OR REPLACE PROCEDURE add_new_classes
(p_number_of_classes NUMBER := NVL(NULL,1), -- This will enter a default value of 1 if the user does not specify a number
p_course_id classes.course_id%TYPE,
p_period classes.period%TYPE,
p_frequency classes.frequency%TYPE,
[code]....
I then use this to test it
BEGIN
add_new_classes(1002,'first','daily',3002);
END;
and the error I get is
Quote:ORA-06550: line 2, column 4:
PLS-00306: wrong number or types of arguments in call to 'ADD_NEW_CLASSES'
ORA-06550: line 2, column 4:
PL/SQL: Statement ignored
1. BEGIN
2. add_new_classes(1002,'first','daily',3002);
3. END;
I know difference between procedure and function.if we want a return value from procedure, we can have OUT parameter. Similarly with function, in addition to returning a value from function, it can also send an OUT parameter value as a return value. That means, in one or the other way we are able to get a return value from both program units. Normally, I would fill a OUT variable with error message when an exception occurs. I use this varaible,after procedure call, to detect if an exception occurred or not. Similar task can be performed by a function, it returns a true/false and a value thru OUT variables.
both program units return values in the form of OUT parameters. Where exactly should we use a function, where exactly should we use a procedure?

difference between Procedure and Function.We Know that Procedure is Basically Used to perform Actions and Functions are Basically Used for Calculations but what would be the exact difference since Actions/Calculations can be done in both Procedure and Functions.Which factors decide whether we need to write a Procedure and in which cases we need Function.

I would like to know if it is possible to get the arguments of a function (or procedure), in the same way as - for example - the "arguments" object in JavaScript.
I have seen the table ALL_ARGUMENTS, for example, that is providing a lot of interesting details, but I still miss the most important for me: the values of the arguments, not only the name, or type, etc...
Something that could be called as soon as the function (or procedure) is run, at the beginning of its process, and that would give a kind of array of arguments values.
i'm trying to make a sp/function for inserting a record and return the new index.The previous code used regular inserts and needed an additional round-trip to get the id before inserting,, since this is part of a import routine performance is an issue.

is it possible to obtain a called procedure/function name within package?
For a measuring and tracing purpose, I would like to store an info at the beginning of each procedure/function in package with timestamp + additional details if needed.
For example:
CREATE OR REPLACE PACKAGE BODY "TEST_PACKAGE" IS
PROCEDURE proc_1 IS
BEGIN
[Code]....
I would like to replace "???????" with a function which would return a name of called procedure, so result of trace data after calling TEST_PACKAGE.proc_2 would be:
11.1.2013 09:00:01 START.*TEST_PACKAGE.proc_2*
11.1.2013 09:00:01 START.*TEST_PACKAGE.proc_1*
11.1.2013 09:00:01 END.*TEST_PACKAGE.proc_1*
