Oracle SQL Functions

There's a function that does what I need.
Can I pass parameters from ODI to Oracle SQL?

I will have to find out. The initial approach was to create a view and import via Knowledge Module...
Do you think that would be a better approach?

Using an Oracle SQL Function from JPA/TopLink

How do I get the return value from a simple (one string input parameter, returns a string) Oracle SQL Function?
Thanks!

If you mean calling a stored function in Oracle, you might try something like:
    ValueReadQuery vrq = new ValueReadQuery();
    SQLCall call = new SQLCall("begin ###res := pkg.funcInp(#inp); end;");
    vrq.setCall(call);
    Query q = em.createNativeQuery("");   // we need a Query; any query would do; we replace its contents below
    ((EJBQuery)q).setDatabaseQuery(vrq);
    q.setParameter("inp", "paramValue");
    String result = (String)q.getSingleResult();
    // #=input; ###=output; ####=input/output;
    // if you want to explicitly specify the type of an output parameter, use #### instead of ###,
    // because pure "output" parameters are always treated as java.lang.StringThis will only work in TopLink Essentials, though. I don't know how to do it in Hibernate. I have dealt mainly with TopLink, and just a little with Hibernate.
In my opinion, it's a HUGE omission not to have support for stored procedures in JPA. Virtually every project I have worked on (in two large companies) has consisted of a large portion of code in stored procedures (sometimes as much as 50% of the overall code). It's a pain to have to go through all that trouble to call the stored procedures.
Also, pay special attention to TopLink's shared L2 cache. If a stored procedure changes something in the database, TopLink won't know about it and chances are that you will end up with stale objects in the cache which you will either have to refresh, or you'd have to invalidate TopLink's cache for these objects.

Oracle sql function to find VARCHAR2 data is numeric

Hi Everyone,
Is there oracle sql function to find whether the VARCHAR2 data is numeric?
Thanks

hi,
see the below example .
with t as
(select '12' as col from dual union all
select '1 2' as col from dual union all
select '2 1 3' as col from dual union all

Utils is a packege then should i use sql function in place of utils.

Hi,
while translating my sp from mssql to oracle few code is converted into : utils
utils is a package i think so is it good to use it or should i find any sql equivenlent function.
then please tel me oracle sql function for utils.patindex();
yours sincerely

Please bear in mind that most people here know Oracle but not SQL Server. So if you wish to use us as a translation service it would be helpful if you told us what the SQL Server function does.
Googling for [url http://msdn.microsoft.com/en-US/library/ms188395(v=sql.90).aspx]PATINDEX() reveals that it is a function which returns the position of a pattern in a string. --The Oracle equivalent is INSTR(). [url http://docs.oracle.com/cd/E11882_01/server.112/e26088/functions080.htm#sthref1174]Find out more.--
Just to prove the point I now think INSTR() is the equivalent of CHARINDEX and what you actually want is one of the regex functions such as REGEXP_INSTR() [url http://docs.oracle.com/cd/E11882_01/server.112/e26088/functions148.htm#sthref1419]Check it out.
Oh, and please, don't use us as a translation service. Read the Oracle documentation or [url http://www.google.co.uk/#q=ms+sql+patindex+oracle&oq=ms+sql+patindex+oracle]use Google.

Using sql functions (min, max, avg) on varray or table collection

Hi,

Does anyone encountered this type of problem ?
Thanks

Yes you can apply Min,Max, Avg... if varray or table collection type is SQL (created in the databaase) UDF, not PL/SQL declared type:

Oracle SQL trim() vs MS Excel clean()

I have some data being extracted from Oracle 11 db views into CSV files.
When importing the data into some other system, said other system's data importer crashes.
I can open the CSV files in MS Excel, apply its clean() function to some columns, paste the values of that, and then the CSV file is a bit smaller, unprintable characters are removed, and data importer in new system is OK.
Its a cumbersome process.
I tried Oracle SQL trim() but it doesn't remove all the chars, it seems, that MS Excel clean() function removes.
Is there a comparable Oracle SQL function that does what [MS Excel clean()|http://office.microsoft.com/en-us/excel-help/clean-HP005209014.aspx] does?
Edited by: 972095 on Nov 19, 2012 2:35 PM

I've used: regexp_replace(your_string,'[[:cntrl:]]') for this.
SQL> declare
2     s varchar2(30) := chr(10) || 'hello' || chr(10);
3 begin
4     dbms_output.put_line('*' || s || '*');
5     dbms_output.put_line('*' || regexp_replace(s,'[[:cntrl:]]') || '*');

T-SQL functions in ORACLE

Use T-SQL functions in ORACLE too, so you can write one script version that works in SYBASE, SQLSERVER and ORACLE when need to use the following functions:
ceiling, charindex, dateadd, datediff, datename, datepart, day, db_id, db_name, getdate, host_id, host_name, left, len, month, replicate, right, space, str, str_replace, stuff, substring, suser_id, suser_name, user_id, user_name and year.
The file [comp_tsql_ORA_schema.txt|http://forums.databasejournal.com/attachment.php?attachmentid=564&d=1258547015] creates the tablespace and schema to put the objects, and the file [comp_tsql_ORA.txt|http://forums.databasejournal.com/attachment.php?attachmentid=569&d=1259256898] creates the functions into the new schema. They will be avaliable for any schema of the oracle instance.
Hope this help!
Any suggestion please contact.

J2EE beta released around 1999. Religious programming wars far preceded that.

I'm no longer convinced that elegance is a desirable trait for a language. So call me a heretic.
Ever tried XLISP? :-)
It's different. Back then it was simply the language itself. And it was not really a religious kind of battle, but more a mine-is-bigger-and-better-than-yours one.
With Java, it is all about The Acrhitecture and the blessed language of Java. ;-)
I wouldn't so much blame J2EE believers for that. I think there is a fundamental complexity to web type paradigms that hasn't been described in a precise and encompassing enough manner to enable correct project planning.The basic problem is that the database is treated as a persistent storage layer only. A bit bucket. And that is exactly what a database is not.
But as it is used that, loads of database features now need to be duplicated in the application layer. Which is done. Very poorly.
Heck, I've even been told that J2EE's 3-tier architecture is not client server. Such ignorance is really unbelievable. Or is it pure stupidity?Until you just made me look it up, I would have thought that too, I'm sure I saw client/server defined as two-tier in the last century. But I have much more stupid misdefinitions to deal with on a daily basis, simply from the multiplicity of paradigms. I tend to retreat into my shell. Hehehe. Know that feeling... These days I rather run away, or set shields to full power, than try to get in yet another frustrating, fruitless and futile discussion with a Java head about the wonders of the J2EE architecture. Or trying to explain that this "new" architecture is predated with what we used in the 80's on mainframe systems with transaction monitors, block devices (the 80's web browsers) and databases - which software layer for software layer was almost identical to "+The Great Architecture+" of today. (and we did it without buzzwords too) ;-)
Client-server is a software architecture and in essence describes 3 basic software components. The User Interface (UI), the Application (APP) and the Database (DB). And there are various ways to put these components together in a client-server architecture. The mistake that the Java fanbois make is thinking that client-server means having the client as the UI and APP as a single component (so-called fat client) and then the DB component as the server.
There are numerous versions of these - including the APP component being a server component (as we now these days more commonly used in over the web).
My beef with the J2EE "+religion+" always has been that client-server is client-server. The fundamentals stay the same.

Calling a pl/sql function from oracle forms

I have written a pl/sql function in a package.
package name- sup

I have written a when-button-pressed trigger .from here I want to call this function.
How can I do that?
Please help..

Thanks a lot..
User may select 20-30 check boxes for respective name & id...then at the end , user will hit OK...from here when-button-click will call a procedure....that will update/insert/delete a table data.The procedure I have written is:-

Setting Oracle Permissions for file access from a pl/sql function

I have a pl/sql function that calls a java method which moves a
file from a directory to another.
Since we are using Linux, Oracle wants some permissions.
Those permissions are set using:
call dbms_java.grant_permission(USER, 'java.io.FilePermission',
FILE, permission)
OK, i want to use this in my pl/sql function, but it doesn't
work.
My function looks like something like this:
-- some pl/sql code
dbms_java.grant_permission(someUSER, 'java.io.FilePermission',
sourceFILE, 'write');
dbms_java.grant_permission(someUSER, 'java.io.FilePermission',
destFILE, 'write');
flag := move(sourceFILE, destFILE);
-- flag is for 1 -> done and 0 -> error
-- some more code ...
The problem is the lines of
dbms_java.grant_permission(someUSER, 'java.io.FilePermission',
sourceFILE, 'write');
do not work!
When i grant permissions manually in sql plus it works great,
but when i do it from the function it does not work!
Any ideas anyone?
Any help would be appreciated.

The command :
dbms_java.grant_permission
(someUSER, 'java.io.FilePermission',sourceFILE, 'write');
is right.
Open sqlplus
Connect as sys or system
type :
execute dbms_java.grant_permission
(someUSER, 'java.io.FilePermission',sourceFILE, 'write');
commit;
try to compile again your procedure...does it work now ?

Oracle SQL-92 Non compliance: When will oracle support empty strings?

Oracle is the only database on the planet that equates an empty string to a null value. For several major versions, Oracle has said "Make sure you don't rely on null and empty string equivalency because it could go away in the future." When will Oracle get with it and support this aspect of the SQL-92 standard (not to mention mathmatical logic)?

You log enhancement requests through Metalink.
The procedure is documented in Metalink document 166650.1 as follows:
How to Log an Enhancement Request:

In other cases, you may be presenting a valuable product enhancement that can improve Oracle product functionality. In all cases, the Support Engineer will be able to qualify your request and pass along the information to Oracle Development.
Once the Support Engineer validates your request, and an agreed upon action plan is created, your Support Engineer will create a new Enhancement Request and provide you with an Enhancement Request tracking number. The BUG search tool on MetaLink can then be used to receive status updates.
Please note that the Support Engineer will close the SR once the enhancement has been logged.

Application Report Missing PL/SQL Functional Area

All,
I just wanted to bring to the ApEx developers something I just noticed... I use the Shared Components > Database Object Dependencies report to make sure all is well before moving applications into production.
The Parsing Errors feature of that report is WONDERFUL! But it seems to be overlooking buttons that use a conditional display based on PL/SQL Function Body Returning a Boolean.

Hi Dan,
I think the place is perfect, but I read once somewhere that "Bug" or "Bug Report" should be in the subject so that's easier to find for the Oracle guys.

Interactive Report with PL/SQL Function Source

Is it possible to create interactive report with PL/SQL function source returing a query? If not, has anyone done any work to simulate the interactive reporting feature for a normal report using API?

I haven't tried that before but you could:
1. create a collection from your result set returned by a dynamic query,
2. create a view on that collection,
3. use the view in your interactive report.
The usability of this proposal depends from a question how "dynamic" your query is - does it always have the same number of columns or not.
