Types of functions cannot used in PL/SQL

I'm trying to find out information on what types of functions cannot be used in PL/SQL. Can someone provide me with some directions and assistance?
Thanks a lot.
Tony

its really depends upon your implementation way..
if u are callinga pl/sql from a trigger, then you can't use any DDL or DML effecting on the same table.
If u are calling a function then it must return only one value, it should not written more than one value.

We're running Oracle 11g

Hi,
In a sub-query (such as the USING sub-query in a MERGE statement), each column in the SELECT clause has to have a unique, valid name.
In an unnested SQL query, you don't have to name the columns at all. If you say
SELECT NVL (dummy, 'FOO')
FROM    dual;In SQL*Plus, it will automatically name the column "NVL(DUMMY,'FOO')" for you, and it doesn't insist that the name be unique.
In a sub-query, you have to explicitly name all the columns, and make sure they're unique; for example
,nvl(fld.MULTSELECT,0)   AS multselect_or_0
To be excruciatingly precise, some versions of Oracle let you get away with not having aliases in certain circumstances, but there's no point in doing so. Always assign unique aliases to columns in a sub-query.

IaaS SQL/VM - how to use an existing SQL VM

Hello
I have a Cloud Service with a Window Web VM and SQL VM. They both are on the same Vnet. Now I want to add a DB using the existing SQL VM. But this VM does not show up of the Server drop down menu in "Specify Database setting"
wizard. What am I missing here?
If I let the DB Wizard add a new server (leveraging PaaS offer for SQL DB), how can I make sure that this new server shows up on my Vnet (the same one where I have Web VM on)? I assume that these VMs needs to be on the same Vnet to be able to communicate
with each other.
Thanks in advance for your help

Hello,
It seems that you had mix up Windows Azure SQL database with SQL Server on Azure VM. When you create a SQL Server virtual machine in Azure, it similar to on-premises SQL Server installed on VM. You can create and manage databases with SSMS.
If you create a SQL database on Management Portal, the SQL database server host a VM of the datacenter, you cannot using the existing SQL Server VM which your created yourself.
When connect to the SQL database from your azure VM which hosted on Cloud Service, there is no need to create a virtual network, just configure the firewall rule of the SQL database server to allow connection from Windows
Azure Serivces.

Cannot use BOOLEAN in Oracle

Why we can't use BOOLEAN in SQL statement but we can use it in PL/SQL statement. But what does that mean? Thanks.

grus wrote:

Oracle however allows you to define your own SQL data types - and create these in a similar way as you would define an object orientated class. These data types have constructors, properties and methods, static class methods - and supports abstract definitions and inheritance. All the basics of an o-o class definition is supported.
This allows you to, for example, create your own boolean data type that you can use in both SQL and PL. Not that this is specifically a good idea for boolean values (as a single character column with a Y/N constraint can do the job equally well to). But even so, to define your own data types is a very powerful feature that can be used to deal with non-common data types in specialised database implementations.
An example of how to create a SQL boolean type was posted some time ago in [this thread|http://forums.oracle.com/forums/thread.jspa?messageID=2116991#2116991].

PLS-00455: cursor 'CUR_1' cannot be used in dynamic SQL OPEN statement

I would suggest that cur_1 refcur_pkg.refcur_t1 is a stongly typed ref cursor i.e. it has RETURN dept%ROWTYPE or something similar in the declaration. You can't use strongly typed ref cursors with dynamic SQL in this way. The declaration should be weakly typed or just use sys_refcursor.

Function which returns multiple values that can then be used in an SQL Sele

I'd like to create a function which returns multiple values that can then be used in an SQL Select statement's IN( ) clause
Currently, the select statement is like (well, this is a very simplified version):
select application, clientid
from tbl_apps, tbl_status
where tbl_apps.statusid = tbl_status.statusid
and tbl_status.approved > 0;
I'd like to pull the checking of the tbl_status into a PL/SQL function so my select would look something like :
select application, clientid
from tbl_apps
where tbl_apps.statusid in (myfunction);
So my function would be running this sql:
select statusid from tbl_status where approved > 0;
... will return values 1, 5, 15, 32 (and more)
... but I haven't been able to figure out how to return the results so they can be used in SQL.
Thanks for any help you can give me!!

EBS ISG using custom PL/SQL functions that return XMLType

Hi,
We have a custom PL/SQL package that we use for interfacing systems and some of the functions in this package ruturn an XMLType. We want to deploy the package functions as web services through the ISG, but it is not working as expected. When deployed through the ISG, the functions with XMLType return type produce a null response from the ISG (they work fine when called in SQL or PL/SQL; functions with non-XMLTypes work fine).
If we change the return type to CLOB (and use getClobVal() on the XMLType) then we get a response from the ISG, but it changes all the angle-brackets in the CLOB (which is still arbitrary XML text) to < > ...
What is the proper way to get the complex XMLType output through the ISG? Anyone have any more experience?
Thanks,
--Walt

Alex,
For the predicate groups that are indexed/stored, the exact operator types (as in equality, inequality, like etc) that are indexed are specified while assigning the default index parameters. In the following example, exf$indexoper is used to specify the list of indexed operators.
BEGIN
DBMS_EXPFIL.DEFAULT_INDEX_PARAMETERS('Car4Sale',
    exf$attribute_list (
       exf$attribute (attr_name => 'HorsePower(Model, Year)',
                      attr_oper => exf$indexoper('=','<','>','>=','<='),
                      attr_indexed => 'FALSE')    --- stored predicate group
END;
/You can find more information about exf$indexoper at
http://download.oracle.com/docs/cd/B28359_01/appdev.111/b28419/t_expfilobj.htm#ARPLS153
Could you confirm that you chose to index 'is null' and 'is not null' while assigning the default index parameters ? This information is available in OPERATOR_LIST column of the USER_EXPFIL_DEF_INDEX_PARAMS view.
Hope this helps,
-Aravind.

How to use type, packages, functions, and procedures in another schema ?

I have two target schema in one OWB project, such as A and B. In a mapping of A, I would like to use some types, packages, functions, and procedures from B. I have tried the method of synonym as suggested, but I could not find the metadata of these when importing ... The only type of synonym I can import is the synonym for table. Is there a bug for synonym?
If I cannot use synonym for this issue, is there another way to solve the problem?

Now, in some instances you will absolutely need to create the second module as Carsten describes, however it should also be noted that you can reference objects in things like Expressions even if you have not loaded up the metadata. It is only when you need strong binding that it becomes neccessary to import objects. For everything else, as long as the reference will resolve at compile-time then you are good to go.
For example, I have a function in one target schema (S1) and a private synonym to it in another(s2). A mapping in the S2 schema has an expression object that uses the synonym to the function in the expression property for a couple of the output attirbutes. The synonym has not been loaded into metadata - indeed OWB has no knowledge of its existance. But it resolves at compile time so the mapping validates and generates successfully.

But after that while i am retrieving records through dblinks from one of my other Oracle 9.2.0.8 databse it's throwing the error : PL/SQL: ORA-22992: cannot use LOB locators selected from remote tables.* This error i am getting in TOAD as well as SQL Developer.
Can anybody tell me how to fix this error ? Because am not able to get the records.
Also am getting another error during retrieving data from some of my tables after migrating i.e the table which having CLOB data type while am accessing to retrieve the records using select query it's throwing the error :
+(The following error has occurred:+
A query with LOB's requires OCI8 mode, but OCI7 mode is used.)
If anyone having any idea kindly share.
Thanks and Regards

Which SQL function to use to get previous month's data?

Hi
The reporting need: Display of two month's payroll run results....current and previous (based on the parameter passed) in Oracle Discoverer.
Data source: A table in which run result values are stored. Of course to be linked to number of other tables.
Can somebody guide me on which SQL function to use to get the data for previous month?
Secondly, as Discoverer does not support parameters, I cannot put parameter in the query itself. I'll be applying parameter later while generating my report.
Please advice.
Thanks and regards,
Aparna

It's not very clear in my head... but you can try :
SQL> select * from test;
ENAM        SAL DT
TOTO       1000 30/05/06
TOTO       1001 20/04/06
TOTO       1002 11/03/06
TATA       2000 30/05/06
TATA       1500 20/04/06
TUTU       3500 30/05/06
6 rows selected.
SQL> select ename, dt, sal currmonth,
            case when trunc(lag(dt,1,dt) over (partition by ename order by dt),'MM') = trunc(add_months(dt,-1),'MM')
                 then lag(sal,1,sal) over (partition by ename order by dt)
                 else null end prevmonth
     from   test
SQL> /
ENAM DT        CURRMONTH PREVMONTH
TATA 20/04/06       1500
TATA 30/05/06       2000       1500
TOTO 11/03/06       1002
TOTO 20/04/06       1001       1002
TOTO 30/05/06       1000       1001
TUTU 30/05/06       3500
6 rows selected.

Just an additional question : do the previous month is current month-1, or is there hole in month suite (e.g. the previous month can be current month-2) ?
