Diff between function,procedure/packages and Diff bet delete,truncate,drop

Dear all
I am your pal ranga from IT capital bangalore india. I would like have detail discussion with respect to subject. Pls discuss
Thanks and Regards
B.Rangarajan

Justin gave good advise but here is the short version of the answer just for the heck of it
Function => stored code suitable for use in the select list of a query and in the where clause conditions that generally accepts one parameter and returns one value. Allows user to extend list of Oracle provided row queries.
Procedure => stored code designed to return one or more values to the caller. Procedures are generally called from other stored code routines or directly from the user application and not as part of a query or DML statement.
Package => a collection of stored procedures and functions
Delete => DML row operation to remove rows from a table
Truncate => DDL operation to quicky and with minimum overhead mark a table and its associated indexes as empty
Drop => DDL operation to remove a table or other object from the database
Maybe these definitions will help until you cover the reading. You can also learn this from the Concepts manual. If you are a DBA this manual is where you should start. For a Developer I would start with the Application Developers - Fundamentals.

Private function / procedure to be used with in a package

Hi All
I wanted to find out how would the definition be for a function which is defined so as to be used/called by the other functions / procedures with in a particular pakage and should not be visible/accessible for any other routine out side the package in which it is defined..
could you please advice me on this? Thanks!
Sarat

It is possible: you can nest one function/procedure in another:
SQL>CREATE OR REPLACE FUNCTION sum_squares(
2     p_a   IN   NUMBER,
3     p_b   IN   NUMBER)
4     RETURN NUMBER
5 IS
6     FUNCTION square(
7        p_n   IN   NUMBER)
8        RETURN NUMBER
9     IS
10     BEGIN
11        RETURN p_n * p_n;
12     END square;
13 BEGIN
14     RETURN square(p_a) + square(p_b);
15 END sum_squares;
16 /
Function created.
SQL>SELECT sum_squares(3, 4) FROM dual;
SUM_SQUARES(3,4)

How to check if column_ name is used by any procedure ,package ,function

Hello
Help Is greatly appreciated .
Kindly please let me know for the folllwoing:
How to check if column_ name is used by any procedure ,package ,function ,trigger or in any dataabse objects

>

In general you can't. Code can always exist outside the database and it is always possible that you have dynamic code and there is no way to find references like that if used by dynamic code. That dynamic code reference could be based on a query stored in a table.
And there is no way of knowing if external code (e.g. a Java app) references that column.
Another issue is that a column could exist in multiple schemas and in multiple objects of different types in those schemas. So a global DB search for 'MY_COLUMN' might turn up references in multiple schemas and you may only care about one schema.
Unfortunately a reference to 'MY_COLUMN' in code could refer to many different objects or to an object in different schemas so how would you resolve those? Especially if you take synonyms into account which can ponit about anywhere.
Why don't you tell us what it is you are really trying to do?
Are you trying to find the references to a particular column? Why? Are you planning on removing/renaming the column? If so then the simplest way is to remove/rename the column and see what objects become invalid. Those invalid objects will have become invalid because that column is no longer available.
As suggested you can use DBA_SOURCE for references in code that use the standard names. But for tables/views you need to use all_tab_columns. And for dynamic code or client code (e.g. a Java application) there is no way.

Calling DB Objects (packages- Pl/SQL procedures) from the ADF

Hi,
1.How can we call DB Procedures/Packages using ADF ?
2. Are there some scenarios which depicts when to use which Layout? & Also any introduction to Layouts in ADF.
Thanks.

Hi,
You can expose your PL/SQL package as web services as well and use it on your layout. check this blog entry about calling PL/SQL from ADF you may find it helpful
http://baigsorcl.blogspot.com/2010/05/calling-plsql-procedure-and-function-in.html
This presentation would help to understand layouts http://blogs.oracle.com/shay/2010/05/adf_faces_layouts_demo_-ahid.html
also you can refer to web user interface guide.

How can I compile all functions, procedures and packages with a script?

I need to compile all functions, procedures and packages of 5 schemas (users) with a script.
How can I do it?
Thanks!

you can create a script to select all invalid objects in those schemas Since Oracle 8 introduced NDS this approach has struck me as a trifle old fashioned. It's much simpler to loop round the query in PL/SQL and use EXECUTE IMMEDIATE to fire off the DDL statements. No scripts, no muss, no fuss.
Having said that, the problem with this approach and also with using DBMS_UTILITY.COMPILE_SCHEMA is that they do not compile all the invalid objects in dependency order. This may result in programs being invalidated by the subsequent compilation of dependencies. This is due to the introduction of Java into the database.
The UTLRP script is much better, because it (usually) avoids cyclic references. But you still may need to run it more than once.
In general it is better to avoid sledgehammer recompilations (like DBMS_UTILITY.COMPILE_SCHEMA, which starts by invalidating all the objects). If we have twenty invalid objects, nineteen of which are dependencies of the twentieth, we actually only need to recompile the master object, as recompiling it will trigger the recompilation of all the others.

Searching strings in procedures, function and packages (OWB)

Hi all,
I'm working on an OMB script to look for a string in procedures, function and packages in OWB. So far, I found how to do it for functions and procedures:
string match -nocase \*text_to_find* [OMBRETRIEVE FUNCTION 'my_function' GET PROPERTIES(IMPLEMENTATION)]
string match -nocase \*text_to_find* [OMBRETRIEVE PROCEDURE 'my_procedure' GET PROPERTIES(IMPLEMENTATION)]
I have tried something similar for packages but it didn't work. Does someone know how to do this search in packages? Any help will be appreciated.
Regards,
Mauricio

Of course, if you are looking for a match in any source - including procedures and packages not imported into OWB, then OMB+ isn't going to be a ton of help as it won't be aware of those other packages.
In that case, you can always find those dependencies by doing a standard select owner, name, type, text from all_source where text like '%YOUR_SEARCH_CRITERIA%' query.
and you can embed that in your OMB+ using the Java/SQL library: How to run SQL from OMB+

Mike

Datatype of parameters defined in PLSQL function and procedures (packages)

Hi,
Require help with this one.
We have written a unit test generator given a PLSQL package name (and several other unit test attributes). This it does by looking at metadata from user_arguments.
We have hit upon a issue with %ROWTYPE parameters.
It apparently splits such arguments into data_level = 0 (the actual ROWTYPE parameter) and data_level = 1 (the individual components of the ROWTYPE) in user_arguments table.
From the data_level = 0 row, i am unable to retrieve the name of the table of which the ROWTYPE is hinged to.
I am looking for this information to be able to declare a variable, initialize it and pass it over to the package.function / procedure being tested.
Is there a way i can retrieve this information (what's the table name its %ROWTYPE of) ?
Thanks,
Krishnan

We have written a unit test generator given a PLSQL package name (and several other unit test attributes)Nice.
Is there a way i can retrieve this information (what's the table name its %ROWTYPE of) ?Unfortunately not that I know of, the underlying anchored datatype is not recorded in USER_ARGUMENTS or the underlying SYS.ARGUMENT$.
Assuming such types were declared at package specification it would be theoretically possible to do this lookup by exploiting the DIANA interface (DIUTIL, DIANA and PIDL packages) but that would be a significant undertaking. Alternatively I suppose you could consider parsing the source code but this again would be a significant undertaking and would not support wrapped code.
The good news is that the compiler does not require that an identically anchored record is passed to the function/procedure, rather the declaration of the attributes of the record must match. In which case you can (simplistically) just declare a local record type with the argument_name, data_type, data_precision, data_scale and/or data_length from USER_ARGUMENTS level 1 then declare a variable of that type and pass it to the function/procedure under test. I say simplistically because there is (albeit rather rarely used) support for nested record types in PL/SQL, hence levels > 1 may exist in USER_ARGUMENTS.

How to query DDL locks on stored procedures/functions and packages?

Hi!
The subject says it all: How do I see existing DDL locks on stored procedures/functions and packages?
While a procedure is executed it can't be deleted or replaced, so there has to be a DDL lock on it. The information does not seem to be in V$LOCK or V$LOCKED_OBJECTS.
Thanks!
Marcus

Hello,
Here you can find an article about the view DBA_DDL_LOCKS:
[http://www.praetoriate.com/int_40.htm]
If you don't have this view on the Data Dictionary, you may have
to execute the "OH/rdbms/admin/catblock.sql" script first.
Hope it can help.

Compiling Procedures/Packages/Functions

I'm fairly new to the arena of compiling Procedures/Packages/Funcitons but I was given the task of updating a development DB with a lot of newly created/updated Objects. I have created a shell script to go through all the new files and create or replace all the new objects in sqlplus. My question is how to compile all the newly created objects and their dependencies correctly? I have been using SQL Developer to verify that everything has compiled but I see that some are marked invalid which I assume is because a dependency was compiled after it. What would be my best way to making sure everything is valid? I hope this makes sense but any help would be appreciated.

You can use a script like this to build your own sql statement to compile the invalid objects. You can add your own statement for other object types at the end with a union, ie TYPE body.
You will probably need to run it repeated until all objects are VALID. You can put it in a PL/SQL block with a loop and execute immediate so reduce the manual work.
--PACKAGE
select 'alter package ' || object_name || ' compile;' from user_objects
WHERE Status = 'INVALID'
and object_type= 'PACKAGE'
union
-- PACKAGE BODY
select 'alter package ' || object_name || ' compile body;' from user_objects
WHERE Status = 'INVALID'
and object_type= 'PACKAGE BODY'
union
--PROCEDURE
select 'alter procedure ' || object_name || ' compile;' from user_objects
WHERE Status = 'INVALID'
and object_type= 'PROCEDURE'
union
--FUNCTION
select 'alter function ' || object_name || ' compile;' from user_objects
WHERE Status = 'INVALID'
and object_type= 'FUNCTION'
union
--TRIGGER
select 'alter trigger ' || object_name || ' compile;' from user_objects
WHERE Status = 'INVALID'
and object_type= 'TRIGGER'
union
--VIEW
select 'alter view ' || object_name || ' compile;' from user_objects
WHERE Status = 'INVALID'
and object_type= 'VIEW'
