Function Overloading in PL/SQL

Hi Guyz,
I have 2 questions regarding function overloading.
1) Is it necessary for the functions to be inside a package to perform function overloading ?
2) I have 2 functions :-
a) function check_hello( P_INPUT1 VARCHAR2, P_INPUT2 NUMBER) RETURN BOOLEAN
b) function check_hello( P_INPUT1 VARCHAR2, P_INPUT2 NUMBER) RETURN VARCHAR2
The difference is the return type . I dont think this is possible since the signature of the arguments are the same. I just need to confirm that its not possible.
Thanks.

Give them different names, or add another argument if you really want them to have the same name.

Function Overloading concept in PL/SQL

hi all,
do we have Function Overloading concept in PL/SQL? If so, how to implement it? can anybody help me out with an example?

Yep.

Error ORA-06502 When using function REPLACE in PL/SQL

Hi,
I have a PL/SQL procedure which gives error 'Error ORA-06502 When using function REPLACE in PL/SQL' when the string value is quite long (I noticed this with a string 9K in length)
variable var_a is of type CLOB
and the assignment statement where it gives the error is
var_a := REPLACE(var_a, '^', ''',''');
Can anyone please help!
Thanks

Even then that shouldn't do so:

Function overloading advantage..

Hi,
One of the package feature is function overloading i.e same name objects with different parameters or different datatype parameters.
how does it(function overloading) increase the performance ?

How to test a simple PL SQL function from another PL SQL script

Hi,
I have created a function. Now i need to test that whether it is returning the correct values or not.
For that, i have written anothe pl sql script and trying to call this function. Im passing all the IN parameters in that function. I assume here that OUT parameters will provide me the result. Im trying to display the OUT parameter one by one to see my result.
I'm using toad as sql client here connected with oracle.
pl sql script:-

Don't look at the function, it might have errors but my primary concern is how to test this function. Once I start doing its testing then only i can understand any bugs(if any).
My pl sql is not so good. Im still learning. I don't understand IN and OUT parameters are.
I just know that IN parameters r those whick we pass in to the function wen we call it and OUT parameters are those through which we get the result.
Thanks in advance

Function as Attribute in SQL raising error

I have a problem
I have a stored procedure 'test_p' and a function 'test_sub'. The Stored Procedure 'test_p' calls function 'test_sub' from a SQL. What I'd like to have is the error from the function to be raised to the 'parent' stored procedure. What happens is, the error occurs in the function. The SQL will therefore not be executed, but code in the stored procedure after the sql will still be executed. It seems that errors from a function called in a sql won't have any impacts to the errorhandling in the stored procedure. Besides that the value of the variable v_errorcode in the stored procedure after the call to the function is still 0 event tough i fill the variable in the exception case in the function.
Anybody has an idea how to raise the error from the underlying function to the stored procedure and whats wrong why the value of the variable v_errorcode in the stored procedure is still 0 after the function call ?
Appreciated urs

Hi,
Call your Function independently.In your code FUNCTION
is not getting executed , so you are not seeing the
error getting raised.
In your code change
open p_ref_cur for select test_sub('E') as tee from dual;
to
x := test_sub('E');
Now call your procedure and you will find the correct results which you are expecting.

Analyze: PL/SQL function body returning an SQL query

I need to obtain the final SQL returned by the PL/SQL function.

I am trying to modify the export_to_excel package from Denes kubicek to provide me an excel from PL/SQL function body returning an SQL query.

begin
l2:= 'Select NAME,ORIGINATED,OWNER,ORIGINATOR,';
l2:= l2 || 'DESIGNATED_UNIT,SOURCE,';
l2:= l2 || 'REFERENCE';
l2:= l2 || ' from MV_DETAILED_DATA';
return l2;
end;
I would like to get the SQL returned from this PLSQL and use it in a procedure to get the Excel.
As you mentioned earlier "copy the generated query string into an application item". [ +In the PL/SQL function body returning an SQL query, copy the generated query string into an application item. The app item value can then be passed as a parameter value to the procedure+ ]
I do not know how to dynamically excute this PLSQL in the region source and obtain the returned value in my procedure.
Best Regard,

Log Function behaving diffently in SQL vs Pl/SQL

Hello
This equation works OK in SQL but its implementation in PL/SQL throws an error:
SELECT CAST(LOG(2,32) as FLOAT) FROM DUAL;
Returns: 5
vs
x FLOAT := 0;
x := CAST(LOG(2,32) as FLOAT) ;

Incidentally I ran into a situation where LOG(2,32) return 5 in SQL but returns 4 where formatted TRUNC(LOG(2,32),0)
Any assistance would be appreciated

Function Call returning old SQL Query

Hello All,
I have a Pipeline Function which creates a SQL within (Dynamic SQL that gets stored in a LONG variable) based on the parameter STRING passed to the function. Inside this function, once the SQL is built, I am inserting this SQL into a log table, for logging purpose.
Note: my function has only one parameter which is a string. This string accepts a name:value pairs with a delimiter which I breakdown inside the function. But this functionality is working fine.
Issue:
When I run the function with parameter with a STRING say (Age = 20, Gender = M) for the first time, it works.
<code>SELECT * FROM TABLE (
PIPE_FUN_SEARCH_PKG.get_search_records ('EMP_AGE:20|EMP_GENDER:M'));
</code>
When I change the parameters to (Age = 20, Gender = F), it gives me the results of the earlier function call.
<code>SELECT * FROM TABLE (
PIPE_FUN_SEARCH_PKG.get_search_records ('EMP_AGE:20|EMP_GENDER:F'));
</code>
When I open the logs, I see the SQL being built is the earlier one.
As a test I closed the session and ran (Age = 20, Gender = F) first. It works fine. When I run a different parameter string, it always mimics the earlier function call.
Is CACHING in play here. I tried both the following:
<code> dbms_result_cache.bypass(FALSE);
dbms_result_cache.flush;
</code>
I tried multiple tests, with different parameters and only the first one runs fine and second one copied the earlier. However, when I open two sessions on two different windows it doesn't happen.
Also, in the Logging table I am capturing the input string as a confirmation, which is coming correctly. But the SQL being build mimics the earlier call.
I tried to set the variable which hold the SQL Statement to empty (v_sql := '';) at the beginning and also at the end. Still no use.
Kindly help if I am over looking anything.
Regards,
Aj

Why a pipeline function? Why dynamic SQL? Are you using +DBMS_SQL+ to create the dynamic cursor? If not, why not? Only +DBMS_SQL+ allows dynamic binding in PL/SQL. Without that, your code will burn a lot of additional CPU on hard parsing and trash and fragment Shared Pool memory.
When I open the logs, I see the SQL being built is the earlier one.
How do you record the current SQL? Are you using a static variable to capture the SQL statement generated?
From what you have described - this is yet another horribly flawed approach in all respects. To data modelling. To relational databases. To Oracle. To SQL.
Reinventing the SQL language for data retrieval as a pipeline function using a funky parameter interface - sorry, I just don't get that. It is an insane approach.

Will ellipsis contradict function overloading

Recently I was reading the Oracle tech magazin. There was an article in it about the next java major release ( J2SE 1.5 tiger). It said the tiger release will support the ellipsis ("...") concept for parameter passing. I have seen this in C/C++ for passing variable number of arguments in functions like printf() or scanf(). I am not sure has there such a concept already in java but if we are going to have such a mechanism, wont that affect the function overloading concept? Please post ur opinions
thanks
boolee

The method will have a signature ending in (I think the current spec says) Object[], so it shouldn't affect the method overloading much.

Function overloading in flex?

Hi
Is it possible to function overloading in flex?
Any send me example.
Regards
D.Mahesh Babu

ActionScript aims to follow the EcmaScript 4 language specification which does not include method overloading. The two have diverged somewhat because EcmaScript 4 is still in a proposal stage and is subject to change. Read more here:
http://en.wikipedia.org/wiki/ECMAScript
A proposed EcmaScript feature called generic functions may offer capabilties similar to method overloading. It is possible such a feature may find its way into ActionScript 4, but I'm not aware of any official announcements to that effect.

i get "Avoid procedure or function calls between a SQL operation and an implicit cursor test.",as far has i know
iff you're doing a sql%rowcount    after an update.. trying to see how many rows were updated... you dont want procedure or function calls between the update and the sql% line
correct me if im wrong and how would i fix it?or maybe i shouldnt
You correct it by NOT executing function calls as part of the UPDATE statement.
1. Issue the function calls BEFORE the update statement
2. save the function results into variables
3. use those variables in the UPDATE statement.
v_rectab1 := vrectab(1);
v_rectab2 := vrectab(21);
v_rectab5 := vrectab(5);

How can i migrate Power Builder 8.0 Function into oracle PL/SQL

Hi Oracle Experts...
How can i migrate Power Builder 8.0 Function into oracle PL/SQL.. I had migrate some of the coding from PB to PL/SQL. But i don't know how can i convert PB structure(here structure is a data type) into oracle PL/SQL.
Instead of structure what is the equivalent in oracle plsql
Below i pasted my POWER BUILDER FUNCTION:

What are you going to return the structure to? What I would normally use here if the code was going to be used by other PL/SQL would be a PL/SQL object type.
However, if PowerBuilder is still in the equation (you're moving the logic to PL/SQL but keeping PowerBuilder for the GUI ), then you'll have to return something else, because PowerBuilder doesn't understand PL/SQL object types. Perhaps passing a REF CURSOR as a OUT argument and populating it from the procedure. PowerBuilder could then retrieve the result of the procedure using a stored procedure based DataWindow.

Function overloading ... Is there any benefit ?

Where is the benefit if I write this ..
using function overloading :
add(Integer, Integer);
add(String, String);
instead of
addInt(Integer, Integer);
addStr(String, String);
Is there any benefit ?

why you are saying "add() *does not contain an argument type name*"?The statement that you are still claiming to find unclear was 'embed the argument type names in the function name'. The function name 'add()' doesn't do that. Your alternative function name 'addInt() does do that. 'Int'. A type name. Embedded in the function name.
Am I missing something ?Yes. I don't see how you can agree that add() is shorter than addInt() without also seeing that the difference consists precisely of the embedded type name. Frankly, I don't think you have been reading very carefully.

Function Overloading in sql

is there any way by which one can over load function with out affecting any change in .net code or sql proc or function which refer that function

No, there is no way to "overload" a function.
However, what you are describing can be done by creating a layer of stored procs and views the .Net code calls instead of direct accessing the database. This gives the SQL developer the ability to change the physical database and change the layer
to match the same output, without changing the .Net code.
