Arrays in oracle

There are some query's to be executed by java code that return more than one rows, but i want this query to be executed by a stored procedure. I am looking for a solution which will return this multiple rows using a parameter in a procedure/Package.
e.g I have emp table that has 10 records, I create a proedure emp_data which will have select * from emp, I want this procedure to return 10 rows.

> there is VARRAY in Oracle - is it different than the array?
A VARRAY is a fixed size (static) array in the SQL Engine. When defining and using arrays in PL/SQL Engine,
these are dynamic (can be extended) arrays (aka PL/SQL "tables").
There are also other differences. The SQL Engine "knows" the VARRAY SQL type and can use it - it has access
to the array's type definition.
The SQL Engine cannot however (directly) use a PL/SQL array - as the type has been defined in the
PL/SQL (and can include non-SQL data types like BOOLEAN). This requires PL/SQL arrays to be casted to
a structure that the SQL Engine can understand (and array data copied from the PL/SQL Engine to
the SQL Engine). Only then can the SQL Engine use a PL/SQL array.
Personally, I do not like using VARRAYs as that does not fit with my views of a relational design. It is
IMO dealing with a bad case of 2nd normal form when using VARRAYs in a SQL table.
Nested tables in a SQL table however can be justified in my view - especially when the child rows of one
parent row have absolutely nothing in common with the child rows from another parent row.
The question as to HOW to use these arrays depend on the requirements - and then selecting the best tool
for the job. Arrays have the same basic data structure, and serve the same basic purpose, irrespective
of the programming language.

How to pass ARRAY to Oracle Procedure

Hi
We are using BC4J with JSP in our project. We need to send an Array to the procedure.
Could somebody provide some info as how this can be achieved.

A while back, I used a SQLJ client to call a Java (also SQLJ) stored procedure and I needed to pass an array of strings to the procedure. I did something like this:
Java Class that was loaded in DB:
public class MyClass
// method that the stored procedure uses
public static void CALL_DOSTUFF(String a,
oracle.sql.ARRAY b,
oracle.sql.ARRAY c)
String[] bb = (String[])b.getArray();
String[] cc = (String[])c.getArray();
doStuff(a,bb,cc);
public static void doStuff(String a,
String[] b,
String[] c)
// process the input
In the database I added the type:
create or replace type STR_ARRAY as table of varchar2(20);
and the procedure:
create or replace procedure CALL_DOSTUFF(a varchar2,
b STR_ARRAY,
c STR_ARRAY)
as
language java
name 'MyClass.CALL_DOSTUFF(java.lang.String,
oracle.sql.ARRAY,
oracle.sql.ARRAY)';
I then used jpub to publish a STR_ARRAY.java file. I compiled this and used it with my SQLJ client to call to the stored procedure. The STR_ARRAY constructor takes a String[], so you do something like this in the SQLJ client:
String x = "X";
String y = {"y1","y2"};
String z = {"z1","z2"};
STR_ARRAY y1 = new STR_ARRAY(y);
STR_ARRAY z1 = new STR_ARRAY(z);
#sql {CALL CALL_DOSTUFF(:x,:y1,:z1)};
Hope this helps.

Sharing in Symetrics Array an Oracle datawerehouse and oracle database 9i

I
i want to know if someone have an sharing in Symetrics Array an Oracle
datawerehouse and oracle database 9i, or any array for high
availability. This because i have to do implement an installation
datawarehouse and db9i on the same arrary. Just know any comment if
whichever with share with me your expertise from any situation with
this, please.
Thanks

Thanks for the reply.
Actually I thought that the OCCI forum was for Object oriented OCI, so while I'm using C++, I'm not using the object oriented side of OCI, just using the normal OCI calls. Guess I should have been a little clearer in my original post.
But my main question really concerned the version of the client and the version of the database which you answered.
Thanks,

Passing arrays to Oracle Stored procedure.

Have any body passed arrays to Oracle stored procedures while the app is running in Weblogic app server. I am able to pass the arrays with regular JDBC connection. If I run the same piece of code using a connection recieved from the datasource of weblogic server, its not working. I am getting serialization errors with the ArrayDescriptor class. Looks like the ArrayDescriptor is not serializable.
Does anybody know solution/workaround to pass arrays ?
Thanks in advance

you could write a wrapper class that extends ArrayDescriptor and implements serializable...
for example your class would look something like this.
public class MyArrayDescriptor extends ArrayDescriptor
implements Serializable
in your regular code use the wrapper class in place of the ArrayDescriptor (it will contain all the same methods as the real ArrayDescriptor) and you should be able to toss your wrapper class anywhere you please.

INSERT into my_table values( l_tab(i) );
end;

any ideas?

I believe when you're doing it with an insert, you're saying "execute this insert statement a bunch of times, here's all the values in advance", which is different than passing an array to a stored procedure where you want it to execute once.
Oracle's ODBC driver doesnt support Associative Arrays (aka index-by tables).
Hope it helps,

Problem passing oracle.sql.ARRAY to Oracle

I am having ClassCastException when I try to pass a oracle.sql.ARRAY to a Oracle Package.
Here is my code:
PreparedStatement stmt = null;
String strArray[] = { "1,2,3,4,5" };
ArrayDescriptor descriptor = ArrayDescriptor.createDescriptor( "TEST_PAC_1.TEST_COLL_2", dbConnection );
//encounter Exception on the line below.
ARRAY array_to_pass = new ARRAY( descriptor, dbConnection, strArray );
String queryStr = "begin TEST_PAC_1.TEST_PROC_2(?); end;";
stmt = dbConnection.prepareStatement(queryStr);
stmt.setArray( 1, array_to_pass );
stmt.execute();
I understand that oracle.sql.ARRAY has been replaced by weblogic.jdbc.vendor.oracle.OracleArray in Weblogic.
MY QUESTION IS: HOW DO I INSERT MY STRING ARRAY INTO THE OracleArray and pass it to the plsql.
Really frustrated searching through the forums for the whole day,
Thanks,

Try this if you are at weblogic 8.1:
Connection con = getConnectionFromDataSource();
Connection vendorConnection = ((WLConnection)con).getVendorConnection();
// use direct oracle connection.
ArrayDescriptor descriptor = ArrayDescriptor.createDescriptor( "TEST_PAC_1.TEST_COLL_2", dbConnection );
vendorConnection.close();
Beware that you should be very careful as you are going to use a direct vendor
connection.
The better aproach is to pass the string array as a delimited string to your storad
procedure and parse it in the SP - then you don't have to mess up with vendor-specific
handling.
Hope this helps.

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.

Problem with database control returning multiple rows as Array using Oracle

Has anybody using Oracle gotten a Database control that
returns multiple rows to work returning an array?
The only way I can seem to return multiple rows is by returning
a RowSet. Returning an array gives me a NullPointerException
(when called within a pageFlow). When calling a database control
that returns an array from a web service I get a
"java.sql.SQLException: ResultSet has no more data." error.
The samples using the pointbase database seem to work, but when I
converted the CustomerDBClient web service to use Oracle, it starts
failing on calling the database control that returns an array
with: "java.sql.SQLException: ResultSet has no more data."
Has anybody gotten this to work using Oracle?
I'm also having some problem returning an Iterator. It seems
to work when called from a web service, but returns nothing
if called from a page flow.
I'm using Oracle 8.1.7 and WebLogic 8.1.
Eric

Do you need a particular service pack installed to return an array of custom object?
I am getting a ResultSet contained no data error when trying.
Thanks,

Unfortunately, returning an Iterator to a JPF (or JSP) from a
database control is broken in WLW 8.1, though it will work inside of
a
JWS or JCS.
There shouldn't be a problem with returning an array of objects out
of Oracle to the JPF, and if you need an Iterator specifically, youcan
wrap the array in an Iterator implementation.
Sorry for the inconvenience.

I get the same error that Eric reported when trying to return an Array
of objects.
It is really frustrating because I can't use much of the built-in control
logic
that WLW provides. All I did was create a data pool for Oracle and a
datasource.
I modified the sample app in C:\bea81\weblogic81\samples\workshop\SamplesApp\WebApp\callJavaControl
to point to that datasource and I get the error that Eric reports above.

Send array to oracle SP

Hello
I'm using .net 4.0 (C#) with oracle 11g.
I wrote a SP that insert data into some tables and I need to send to it two parameters which are arrays of decimals (I don't know in advance how many items will be in the array), I searched the net for a solution but couldn't find an answer...
I tried to use varrays (although they are not dynamic) but still no success, I recieved the following exception when running the C# code:
Unknown datatype System.Decimal[] for parameter value of type Object.
Here is the SP I wrote:
create type varrayFE as varray(1000) of varchar(decimal);
create type varrayBE as varray(1000) of varchar(decimal);
create or replace
PROCEDURE CI_INSERT_HISTORY_REPORT
Report_Name_Param IN VARCHAR2 , User_ID_Param IN NUMBER , Report_Type_Param IN NUMBER
, RootFE_Param IN NUMBER , Time_Period_Param IN NUMBER , Hours_Param IN NUMBER
, SW_Param IN NUMBER , FE_Param IN varrayFE , BE_Param IN varrayBE
) AS
BEGIN
INSERT INTO CI_History_Reports
