Creating arrays in PL-SQL

hello,
please help me to create an array in plsql.
i want to store a string in this array so that i can fetch one element at a time.
also the array can be extended dynamically.

What Werwer did is define a nested-table of a column. It's sort of a varray except that you can have unlimited size.
Now the .EXTEND must be used to insert values into the nested-table and varray. It makes room for the value.
In his example (using two values) he could have simply had: str_array.extend(2); make room for two values
and let the other .extend off.
So, you can define a varray, but only if you know you will not 'store' more than a pre-defined number of values.
Werwer
I have done a bit more research and it appears you are using the syntax for varrays. Shouldn't this be declared as a varray rather than a table ?
(I'm not sure as I have always used index-by tables and not varrays.)
Varrays have some restrictions which index-by tables do not have, so do they have any advantages ?

How to create Array type parameter of Oracle 10.2.0.1.0 in java

I create a collection type with:
CREATE OR REPLACE
type TEST_User.T_ARRAY AS TABLE OF VARCHAR2(100);
and in java code, I use following code to create a parameter of this type, and set it for a procdure
String[] userMakeArray = new String[]{"V", "N", "A"};
oracle.sql.ArrayDescriptor descriptor = oracle.sql.ArrayDescriptor.createDescriptor("TEST_User.T_ARRAY", cn); // cn is connection instance to database
oracle.sql.ARRAY array = new oracle.sql.ARRAY(descriptor, cn, userMakeArray);
((oracle.jdbc.OracleCallableStatement)call).setArray(8, array);
when i use this to call procedure in Oracle 10.1, it work well.
In Oracle 10.2, it does not work well.
For test, I can execute procedure well in sql plus, but in java client, I found that array contains three items "Null", while array is correct when conect to 10.1 enviroment.
does anybody know what's the reason for this.
thanks a lot.

Hi,
Too long to copy/paste here but i have a simpler working example of Nested Table of VARCHAR2 type against 10.2.0.x, in chapter 3 and 8 of my book:
create or replace type NTab_Vc2 as TABLE of varchar2(30)
create table NSTableTab (id int, numnt NTab_Num, vc2nt NTab_Vc2, datnt
NTab_Dat)
nested table numnt store as NSTabNum,
nested table vc2nt store as NSTabVc2,
nested table datnt store as NSTabDat;
insert into NSTableTab values (1,
NTab_Num(1, 2, 3, 4, 5, 6, 7, 8, 9, 10),
NTab_Vc2 ('One', 'Two', 'Three', 'Four', 'Five', 'Six', 'Seven', 'Eight', 'Nine', 'Ten'),NTab_Dat('01-JAN-2003', '02-JAN-2003', '03-JAN-2003', '04-JAN-2003',
'05-JAN-2003', '06-JAN-2003', '07-JAN-2003', '08-JAN-2003',
'09-JAN-2003', '10-JAN-2003')
// The following code snippet retrieves and returns a
// NTab_Vc2 as a java.sql.Array
OraclePreparedStatement ps = (OraclePreparedStatement)
conn.prepareStatement ("SELECT VC2NT FROM NSTableTab
WHERE ID = ?");
ps.setNUMBER (1, id[0]);
OracleResultSet rs = (OracleResultSet) ps.executeQuery();
Array a = null;
while (rs.next())
a = (Array) rs.getObject(1);
ps.close();
return a;

PL/SQL array passed to SQL IN

Hi,
I have a PL/SQL array which type is defined like this:
create or replace type type_id_array as table of number(6, 3);
then i create a variable and initilaize:
var_1 type_id_array;
var_1 := .....
then i have a select statement.
select * from table t where t.id in(var_1)
That's it, i want to use the array in an SQL in. This seems not possible.
Can you explain why? Any alternate solutions?
Thanks

Can you explain why? Any alternate solutions?SQL supports set commands specifically for arrays (in addition to the using the TABLE() method mentioned). For example:
SQL> create or replace type TNumbers is table of number;
2 /
Type created.
SQL>
SQL> declare
2          numList TNumbers;
3          cnt     integer;
4 begin
5          numList := new TNumbers(1,2,3,4,5,6,7);
6          select
7                  count(*) into cnt
8          from    user_objects
9          where   TNumbers(object_id) member of numList;
10          DBMS_OUTPUT.put_line( 'cnt='||cnt );

Need To Create a table in Sql Server and do some culculation into the table from Oracle and Sql

Hello All,
I'm moving a data from Oracle to Sql Server with ETL (80 tables with data) and i want to track the number of records that i moving on the daily basis , so i need to create a table in SQL Server, wilth 4 columns , Table name, OracleRowsCount, SqlRowCount,
and Diff(OracleRowsCount - SqlRowCount) that will tell me the each table how many rows i have in Oracle, how many rows i have in SQL after ETL load, and different between them, something like that:
Table Name OracleRowsCount   SqlRowCount  Diff
Customer                150                 150
0
Sales                      2000                1998
2
Devisions                 5                       5

(I can add alot of SQL Tasks and variables per each table but it not seems logicly to do that, i tryid to find a way to deal with that in vb but i didn't find)
What the simplest way to do it ?
Thank you
Best Regards
Daniel

Hi Daniel,
According to your description, what you want is an indicator to show whether all the rows are inserted to the destination table. To achieve your goal, you can add a Row Count Transformation following the OLE DB Destination, and redirect bad rows to the Row
Count Transformation. This way, we can get the count of the bad rows without redirecting these rows. Since the row count value is stored in a variable, we can create another string type variable to retrieve the row count value from the variable used by the
Row Count Transformation, and then use a Send Mail Task to send the row count value in an email message body. You can also insert the row count value to the SQL Server table through Execute SQL Task. Then, you can check whether bad rows were generated in the
package by querying this table.

How to bind arrays to PL/SQL stored procedure using OCI?

Hi,
We are having problems trying to bind arrays to PL/SQL stored procedure using OCI. Here is the situation:
- We have a stored procedure called "GetVEPFindTasks" with the following interface:
PROCEDURE GetVEPFindTasks (
p_ErrorCode OUT NUMBER,
p_ErrorMsg OUT VARCHAR2,
p_RowCount OUT NUMBER,
p_VEPFindTasks OUT t_VEPFindTaskRecordTable,
p_MaxTask IN NUMBER);
t_VEPFindTaskRecordTable is a record with the following entries:
TYPE t_VEPFindTaskRecord IS RECORD (
RTCID NUMBER,
TransNum NUMBER,
TransTimestamp VARCHAR2(20),
Pathname1 image_data.pathname%TYPE,
Pathname2 image_data.pathname%TYPE,
Pathname3 image_data.pathname%TYPE,
OperatorID operator.id%TYPE);
- Now, we are trying to call the stored procedure from C++ using OCI (in UNIX). The call that we use are: OCIBindByName and OCIBindArrayOfStruct to bind the parameters to the corresponding buffers. We bind all parameters in the interface by name. Now, we do bind the record's individual item by name (RTCID, TransNum, etc.), and not as a record. I don't know if this is going to work. Then, we use the bind handles of the binded record items (only record items such as RTCID, TransNum, and NOT error_code which is not part of the record) to bind the arrays (using OCIBindArrayOfStruct).
All of the parameters that are binded as arrays are OUTPUT parameters. The rest are either INPUT or INPUT/OUTPUT parameters. Now, when we try to execute, OCI returns with an error "Invalid number or types of arguments" (or something to that sort... the number was something like ORA-06550). Please help...
Is there any sample on how to use the OCIBindArrayOfStruct with PL/SQL stored procedures? The sample provided from Oracle is only for a straight SQL statement.
Thank's for all your help.
** Dannil Chan **

As you said:
You have to pass in an array for every field and deconstruct/construct the record in the procedure. There is no support for record type or an array of records. Can you give me a example? I'am very urgently need it.

Create statspack report using sql*developer

Hello,
While connecting with PERFSTAT user I can not create statspack report using SQL*Developer:
@?/rdbms/admin/awrrpt
Error starting at line 1 in command:
@?/rdbms/admin/awrrpt
Error report:
Unable to open file: "?/rdbms/admin/awrrpt.sql"
Actually, my problem or question is that how can PERFSTAT user can generate statspack reports from a Client side. What is the other way a non-dba can see the snapshots histroy and generate report (by using perfstat user ) while joing tables or using views?
Thanks a lot.
Best Regards

Hi,
for awr reports @?/rdbms/admin/awrrpt (you need EE+Diagnostic Pack) there is a solution.
Grant execute dbms_workload_repository to <user>;
Grant select_catalog_role to <user>;
get all SNAP_IDs
SELECT TO_CHAR(s.startup_time,'YYYY.MM.DD HH24:MI:SS') INSTART_FMT,
 di.instance_name INST_NAME,
 di.db_name DB_NAME,
 s.snap_id SNAP_ID,
 TO_CHAR(s.end_interval_time,'YYYY.MM.DD HH24:MI:SS') SNAPDAT,
 s.snap_level LVL
FROM dba_hist_snapshot s,
 dba_hist_database_instance di
WHERE di.dbid = s.dbid
 AND di.instance_number = s.instance_number
 AND Di.Startup_Time = S.Startup_Time
ORDER BY snap_id desc;
Select * From Table(Sys.Dbms_Workload_Repository.Awr_Report_Html(DBID, 1, BEGIN_SNAP_ID, END_SNAP_ID));
For statspack i don't know a solutuion. I think the best idea is, create a job to make the statspack report on the server side and access it via external tables or mail them forward to you.

Updating array data in sql database

HI,
Im facing problems in updating array data in SQL database.
As of now, i am able to write an "insert" query and insert array data in an image datatype field. Im using image datatype because the array size is very big(around 80,000 x and y values).
Althoug inserting data is easy im unable to write a query to update this data.
Referring to the help of SQL server and Labview database connectivity toolkit, i came across a method of accessing image datatype....using textpointers, which are 16 bit binary values and using the WRITETEXT function instead of the UPDATE function.
but the problem im facing is that ive to pass the array as a 2d string array in the query as a result the updated array is retrieved in the form of a string a
nd not as an array. how do I get over this problem?

Hi Pavitra,
I'm not very clear on how you have inserted the data into your application, but I do know that when you call the UPDATETEXT or WRITETEXT function you use the TEXTPOINTERS to point to the first location of a 1d array. So, depending on how you've stored the data, you may have problems updating your data if you're looking at it as a 1d array instead of how you originally formatted it. If you are able to successfully access the data as a 1d array, you can use the database variant to data type vi and pass in a string array constant for the data type. This will convert the variant datatype into whatever you specify. You may have to index the row and column of the variant (you receive a 2d array of variant) first before you convert. If possible, can yo
u provide some more detail and maybe some example code of how you perform the insert and plan to do the update? I can probably give you a better solution if I know how you are formatting the data. Thanks!

How to create a view in sql workshop depending on an application item value

Hello,
How coud I create a view in SQL worshop based on an application item value? For example select id, name
from gg_provider
where user = ' || :USER
So basically each user would have it's own view. But it does not work like that. I think when I use :USER then the database takes database user not the user logged in to apex application. How would be possible to use application user to create the view?
Thank you very much.

Instead of
:APP_USER
use
v('APP_USER')

Problem in Creating a JDBC System - SQL Server

Hi All
I failed in creating a JDBC System(SQL Server). I am using SAP EP 7.0 SP 9. I tried to create the JDBC system with the following properties:
I am listing them Category wise:
Connection Properties:
1. Connection Timeout: 300
2. Connection URL: jdbc:sap.sqlserver://<server name> : <port name>; DatabaseName=master
3. Driver Class Name: com.sap.portals.jdbc.sqlserver.SQLServerDriver
4. Validate Connection: Yes
UserManagement Properties:
5. User Mapping Type: admin;user
Please help me out in making this work. And let me know if any changes to incorporated.
Regards,
Vijay.

Hi vijay,
I have tried this thing sometime back. But when i create a JDBC system, I never give the Connection Timeout and change the Validate Connection from No to Yes. I just give the Connection URL and the Driver Class Name in the Connection Properties dropdown.
Try making these changes and check whether the user mapping is done correctly. Also check whether the Connection URL and the Driver Class Name are correct or not. Have a look at the following link:
<a href="https://www.sdn.sap.com/irj/sdn/wiki?path=/display/VC/JDBC%2bConnection%2bSetup">https://www.sdn.sap.com/irj/sdn/wiki?path=/display/VC/JDBC%2bConnection%2bSetup</a>
Let me know if this works.

Learning how to look things up in the documentation is time well spent investing in your career. To that end, you should drop everything else you are doing and do the following:
Go to docs.oracle.com.
Locate the link for your Oracle product and version, and click on it.
You are now at the entire documentation set for your selected Oracle product and version.
BOOKMARK THAT LOCATION
Spend a few minutes just getting familiar with what is available here. Take special note of the "books" and "search" tabs. Under the "books" tab (for 10.x) or the "Master Book List" link (for 11.x) you will find the complete documentation library.
Spend a few minutes just getting familiar with what kind of documentation is available there by simply browsing the titles under the "Books" tab.
Open the Reference Manual and spend a few minutes looking through the table of contents to get familiar with what kind of information is available there.
Do the same with the SQL Reference Manual.
Do the same with the Utilities manual.
You don't have to read the above in depth. They are reference manuals. Just get familiar with what is there to be referenced. Ninety percent of the questions asked on this forum can be answered in less than 5 minutes by simply searching one of the above manuals.
Then set yourself a plan to dig deeper.
- *Read a chapter a day from the Concepts Manual*.
- Take a look in your alert log. One of the first things listed at startup is the initialization parms with non-default values. Read up on each one of them (listed in your alert log) in the Reference Manual.
- Take a look at your listener.ora, tnsnames.ora, and sqlnet.ora files. Go to the Network Administrators manual and read up on everything you see in those files.
- *When you have finished reading the Concepts Manual, do it again*.
