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.
View 4 RepliesI 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?

This is a big table to get the it's taking 8 minutes time, so that I tried the following SQL to get the count quickly.
SELECT num_rows FROM all_tables WHERE table_NAME='BIG_TABLE'
and owner='APP'; --Number of records 237213998
But I got the different count for the two SQLs. Why there is a difference in the count. Which one is correct.
Want to understand difference between Concat function and "||" operator. I am getting the same result for both. Below is the test case for your reference.
Select 'H '||' S' From Dual;
--Output H S
Select Concat('H ',' S') A From Dual;
--Output H S
Select Length('H '||' S') A From Dual;
--Output 6
Select Length(Concat('H ',' S')) A From Dual;
--Output 6
Explain with the best example for difference between translate and replace function.

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:

2. add_new_classes(1002,'first','daily',3002);

Is it possible to use WITH statement in an Oracle procedure or function?
I've had problems compiling a procedure with "WITH" statement.
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*
11.1.2013 09:00:01 END.*TEST_PACKAGE.proc_2*
I tried to use "dbms_utility.format_call_stack" but it did not return the name of procedure/function.
