How to pass an array to a function from a SELECT statement

Hi all. I have a problem with passing an array to a function directly from a SELECT statement.
Here is what I want. If I have a function
function AAA(arrayVar <ArrayType>) return number;
I want to be able to call this function this way
select AAA((2,3,4))
from dual
or this way
select AAA((10,12))
from dual
In other words I want to be able to pass an arbitrary number of numbers to the function. And I want this to work in a SELECT statement.
Does anyone have any ideas how to implement this? What <ArrayType> should I use?(I've read about VARRAY, nested tables in the Oracle documentation but as far as I've understood these array types are meant to be used within PL/SQL blocks).
I found only this http://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:208012348074 through Google but it didn't help me.
Thank you in advance.

> What <ArrayType> should I use?
SQL data types - as 3360 showed above. You cannot use PL/SQL structures and user types in the SQL Engine.
You can however use all SQL structures and types in PL/SQL.
Arrays in SQL is created as collection type - basic o-o. The collection type (or class) serve as a container for instantiated objects or scalar type.
This is covered in detail in [url http://download-uk.oracle.com/docs/cd/B19306_01/appdev.102/b14260/toc.htm]

Pass string array to Oracle function from Web page

Hi. I need to pass a two-dimensional array of string values to an Oracle function from an ASP.NET page. Is there an efficient way to accomplish this? I'm thinking I'll have to create a long string with special delimiters,
|12345^4.000|67890^3.670|.....
I'd parse the string on Oracle and break it into its component parts. In this example, each "record" is separated by the bar "|" and each field is separated by the up arrow "^". So each record has two fields.
Is this a good approach? Your input is much appreciated. Thanks.

In PL/SQL, it is easy enough to define a record type with two attributes and declare a store procedure that takes in an array of those parameters. I know that from Java it is possible to create and pass in such an array. I would suspect that the same is possible from .Net but I am not a competent .Net developer.

How to pass rowtype argument to a function from select statement?

Hi all!
I have function that takes mytable%rowtype as in parameter. can I pass entire row of mytable to the function from select statement? kind of
select myfunction(mytable.*) from mytable where ....
Thanks in advance

The function can be used in a SQL statement only if it accepts SQL types and returns SQL type. %ROWTYPE being PL/SQL construct and not a SQL datatype, can not be used in this context.

Using TestStand How I pass an array of data into a DLL (IPC3.dll) for serial communication

I am ussing a DLL created by another party. I have the list of the C declaretions. I have been able to write a seq that can turn the comport ON/OFF or select a different port but I have not been able to send or recieved any data. I have created an array of bytes(unsigned 8-bit integers)to send and recieved data but nothing goes out or in.

Hi Toro,
There is an example in your \Examples\AccessingArrays\PassingArrayParametersToDLL directory that illustrates exactly how to pass TestStand arrays as arguments to dll functions. The source files for the .dll are located in the same directory.
For more information on passing arrays as parameters to modules you should read the "DLL Flexible Prototype Adapter" section of Chatper 13 in the TestStand User Manual, and pay special attention to the subsection entitled "Array Parameters". You can access the User Manual from the TestStand Start Menu group, the TestStand Sequence Editor's Help menu, the \Doc directory, or online at the following link:

How to pass int array as an IN parameter to PLSQL Procedure

Hi,

Thanks,

Hi,
The best way to do what you want depends on what you want. Start by describing what you need to do. It's best to post some sample data (CREATE TABLE and INSERT statments) and what results you want from that sample data. (See the forum FAQ: https://forums.oracle.com/message/9362002)
If you have ideas about how to do the job (e.g., populating a temporary table) it can be helpful to include those, too, but distinguish clearly between WHAT you need to do and HOW you might do it.
As Bencol suggested, a SYS_REFCURSOR might be the best way to pass back the results.
Since you didn't post your table, or even describe what you wanted to do with it, I'll illustrate using scott.emp, which is probably on your system.
Say you wanted a procedure that took a DATE as an argument, and returned a some designated columns (empno, ename and hiredate in the example below) for all employees hired on or after the given DATE. You might write a procedure like this:
CREATE OR REPLACE PROCEDURE hired_since
(   start_date IN   DATE
,   out_data    OUT SYS_REFCURSOR
AS
BEGIN
    OPEN out_data FOR
        SELECT empno, ename, hiredate
        FROM    scott.emp
        WHERE   hiredate >= start_date;
END hired_since;
SHOW ERRORS
You can test it in SQL*Plus like this:
VARIABLE   c REFCURSOR
EXEC hired_since (DATE '1982-01-01', :c);
PRINT :c
The output I got from this test was:
     EMPNO ENAME      HIREDATE
      7788 SCOTT      19-APR-87
      7876 ADAMS      23-MAY-87

How to pass runtime parameters to MySQL Query from xMII server

Please can anybody help in How to pass runtime parameters to Orcle Query from xMII server

The answer is the same as for your other thread. The mechanism is the same regardless of the end database. The SQL syntax will be different for each database vendor depending upon which functions you are invoking. The main areas of difference between SQL Server, Oracle, DB2, etc. deal with dates (times also) and strings, but there are others as well.

thanks for your reply
i 'm doing what exactly you mention here .
my problem here is
i have 15 columns
i am executing a query based on the values of the column(column name) in the target page
1)here i am passing(all) the column values to the next page-but i want to pass only one column values(column name)
when i click on any cell of that column
OR
2)i can pass all column name to target page -there(in the target page) i can filter out
i think option 1 would good if you filter out the unwanted columns

It works the same way as I described in this thread [How to pass runtime parameters to MySQL Query from xMII server]. It does not matter the datasource MII will work the same for all queries, at least for passing in parameters. How to write those queries and their datatypes will be the differences.

Return multiple values from a function to a SELECT statement

I hope I've provided enough information here. If not, just let me know what I'm missing.
I am creating a view that will combine information from a few tables. Most of it is fairly straightforward, but there are a couple of columns in the view that I need to get by running a function within a package. Even this is fairly straightforward (I have a function named action_date in a package called rp, for instance, which I can use to return the date I need via SELECT rp.action_date(sequence_number).
Here's the issue: I actually need to return several bits of information from the same record (not just action_date, but also action_office, action_value, etc.) - a join of the tables won't work here as I'll explain below. I can, of course, run a separate function for each statement but that is obviously inefficient. Within the confines of the view select statement however, I'm not sure how to return each of the values I need.
For instance, right now, I have:
Table1:
sequence_number NUMBER(10),
name VARCHAR(30),
Table2:
Table1_seq NUMBER(10),
action_seq NUMBER(10),
action_date DATE,
action_office VARCHAR(3),
action_value VARCHAR(60),
I can't simply join Table1 and Table2 because I have to do some processing in order to determine which of the matching returned rows I actually need to select. So the package opens a cursor and processes each row until it finds the one that I need.
The following works but is inefficient since all of the calls to the package will return columns from the same record. I just don't know how to return all the values I need into the SELECT statement.
CREATE VIEW all_this_stuff AS
SELECT sequence_number, name,
rp.action_date(sequence_number) action_date,
rp.action_office(sequence_number) action_office,
rp.action_value(sequence_number) action_value
FROM table1
Is there a way to return multiple values into my SELECT statement or am I going about this all wrong?
Any suggestions?
Thanks so much!

Hi,
What you want is a Top-N Query , which you can do using the analytic ROW_NUMBER function in a sub-query, like this:
WITH     got_rnum     AS
     SELECT     action_seq, action_dt, action_office, action_type, action_value
     ,     ROW_NUMBER () OVER ( ORDER BY action_date
                               ,            action_seq
                         ,            action_serial
                       ) AS rnum
     FROM     table2
     WHERE     action_code     = 'AB'
     AND     action_office     LIKE 'E'     -- Is this right?
SELECT     action_seq, action_dt, action_office, action_type, action_value
FROM     got_rnum
WHERE     rnum     = 1
;As written, this will return (at most) one row.
I suspect you'll really want to get one row for each group , where a group is defined by some value in a table to which you're joining.
In that case, add a PARTITION BY clause to the ROW_NUMBER function.
If you'd post a little sample data (CREATE TABLE and INSERT statements), I could show you exactly how.
Since I don't have your tables, I'll show you using tables in the scott schema.
Here's a view that has data from the scott.dept table and also from scott.emp, but only for the most senior employee in each department (that is, the employee with the earliest hiredate). If there happens to be a tie for the earliest hiredate, then the contender with the lowest empno is chosen.
CREATE OR REPLACE VIEW     senior_emp
AS
WITH     got_rnum     AS
     SELECT     d.deptno
     ,     d.dname
     ,     e.empno
     ,     e.ename
     ,     e.hiredate
     ,     ROW_NUMBER () OVER ( PARTITION BY d.deptno
                               ORDER BY         e.hiredate
                         ,                e.empno
                       ) AS rnum
     FROM     scott.dept     d
     JOIN     scott.emp     e     ON     d.deptno     = e.deptno
SELECT     deptno
,     dname
,     empno
,     ename
,     hiredate
FROM     got_rnum
WHERE     rnum     = 1
SELECT     *
FROM     senior_emp
;Output:
.    DEPTNO DNAME               EMPNO ENAME      HIREDATE
        10 ACCOUNTING           7782 CLARK      09-JUN-81
        20 RESEARCH             7369 SMITH      17-DEC-80
        30 SALES                7499 ALLEN      20-FEB-81
By the way, one of the conditions in the query you posted was
action_office     LIKE 'E'which is equivalent to
action_office     = 'E'(LIKE is always equivalent to = if the string after LIKE doesn't contain any wildcards.)
Did you mean to say that, or did you mean something like this:
action_office     LIKE 'E%'instead?
