I am describing a SQL statement to get it's column list:DECLARE
cur NUMBER;
col_cnt INTEGER;
rec_tab DBMS_SQL.DESC_TAB;
[Code]....
Now I need to get out the columns list from rec_tab.col_name and put it to my_colls collection. Have Oracle any build-in to do that?
There is a nested table with in a nested table type and i want to print the value and again assign a new value to the next subscript and i have tried a lot but couldn't find any solution.
declare
type type_name is table of varchar2(10);
type type_name1 is table of type_name;
names type_name1:=type_name1(type_name('hello'));
begin
-----HOW TO PRINT A VALUE--------
-----HOW TO ASSIGN A NEW VALUE TO NEW SUBSCRIPT
null;
end;
1) need to print the values of names(1)
2)Assign a value to names(2)
My collection is not working as expected, what could be the issue here. This is what i did,
1. I created a collection in a process to fire on page load
if apex_collection.collection_exists(p_collection_name=>'MMMM') then
apex_collection.delete_collection(p_collection_name=>'MMMM');
end if;
APEX_COLLECTION.CREATE_OR_TRUNCATE_COLLECTION(p_collection_name => 'MMMM');
2. On my page i have a text field P1_text1 when i enter value into text field like ="sample data" i want this data loaded into my collection, so i created a button and added a process(on submit - before computations...) so it should insert into the collection when i click the button but no data is loaded, process:
APEX_COLLECTION.ADD_MEMBER(
p_collection_name => 'MMMM',
p_c001 => :P1_TEXT1,
p_c002 => 'TESTDATA' );
3. when i run the below query it shows "no data found" ,
SELECT c001,c002
FROM APEX_COLLECTIONS
WHERE collection_name = 'MMMM';

A table X : NUM, INST are column names
NUM ----- INST
1234 ----- 23,22,21,78
2235 ----- 20,7,2,1
1298 ----- 23,22,21,65,98
9087 ----- 20,7,2,1
-- Based upon requirement :
1) Split values from "INST" Column : suppose 23
2) Find all values from "NUM" column for above splitted value i.e 23 ,
Eg:
For Inst : 23 ,
It's corresponding "NUM" values are : 1234,1298
3) Save these values into
A table Y : INST, NUM are column names.
INST NUM
23 1234,1298
1) I have a thousand records in Table X , and for all of those records i need to split and save data into Table Y.Hence, I need to do this task with best possible performance.
2) After this whenever a new data comes in Table X, above 'split & save' operation should automatically be called and append corresponding data wherever possible..

I need to select multiple columns but only have 2 of them which are distinct. For instance if i have
userid lastname firstname city country time
1 jones tom lon gb 2:25
2 wall paul la usa 2:30
1 jones tom lon gb 2:50
3 smith jane ny usa 2:55
what i would want to do is select all the columns but avoid duplicate lastname-firstname combination rows. The problem is if i use a group by i have to include all the columns and because time is different i will get tom jones twice. a way of getting round this so i can select all the columns but only 1 row of tom jones.
I have a table with, for example, three columns: A, B,C.
I execute on this table only one select: CODESELECT * FROM TABLE WHERE A = :1 AND B=:2
Column A has a lot of distinct values (numbers), but B can have only two values: 'Y' or 'N' (cardinality about 50%/50%). It is worth to create index on two columns: A, B? Does query using index on A column will be much slower than using index on A, B?
I have in my database (OLTP-System) a table with about 6000000 records and a zise of about 2GB.
the way to create multi_column indexes on the table?
What are the rule to define the best-position of a column in an index?
index_1(col_1,Col_2,col_3) and not [ (col_1,Col_3,col_2) or (col_2,Col_3,col_1) or (col_2,Col_1,col_3) or (col_3,Col_2,col_1) or (col_3,Col_1,col_2) ] ?
What is the advantage of collections over CURSOR? What is the use for collections and when collections is used?

explain slow performance of multicolumn indexes on oracle 11g R2 observed in the following scenario? A multi-column index (b-tree index) not partitioned, not unique, not reversed with 3 columns.
A series of queries are run using all 3 columns. The performance hit comes when the first order column values changes. So, maybe after 10 select queries the value changes. The 2nd and 3rd order columns are changing throughout the series of select calls, but no performance bottleneck it hit then.
Is there any table except (global temp table and permanent table) which can be used to store data and be used in inner, left and right join for a session.

I have an existing Procedure that uses a ref cursor as a parameter. The procedure currently simply selects data into the ref cursor using an OPEN FOR and then exits.
I have a need to extend the processing of the procedure. This will mean retrieving extra columns in the select and also removing some of the retrieved records.
I have the constraint that the definition of the REF CURSOR (which is based on a record type as follows) cannot be modified.
TYPE t_charge
IS
RECORD (
id number,
date_from invoice_detail.from_date%TYPE,
date_to invoice_detail.to_date%TYPE,
description invoice_detail.desc_text%TYPE,
amount invoice_detail.amount%TYPE
);
TYPE t_charge_cursor IS REF CURSOR RETURN t_charge;
The procedure does this
PROCEDURE get_bill_lines (
p_bill_id IN NUMBER,
bill_lines_list OUT t_charge_cursor )
IS
OPEN bill_lines_list FOR
SELECT id, from_date, to_date, desc_text, amount
from invoice_table
where id = p_bill_id;
I am thinking instead of selecting directly into the bill_lines_list parameter I will use a local REF CURSOR to select into a COLLECTION. I can then do some work on the collection, similar to below:
PROCEDURE get_bill_lines (
p_bill_id IN NUMBER,
bill_lines_list OUT t_charge_cursor )
TYPE t_local_charge
IS
RECORD (
[code].....
This all works fine, but the question is, how do I then put the collection into the bill_lines_list REF CURSOR where the '*** HERE ***' comment is so I can send the existing REF CURSOR structure back? (Remember I cannot change any definition that is referenced externally)

I need to check if a small collection contains a specific value. I know I can use the .exist method to let me know if the nth element exists. But is there a similar syntax for checking if an actual value exists?
So the below collection has 6 values (300,301,310,320,400,410) after the cursor values are fetched. I want to use something similar to the below exists syntax in order to search the collection for a value (rather than position) within an IF statement.
The below code shows the kind of thing I want to do. Currently, unless my test value (310) is in the range 1 to 6 the test will always return FALSE. But is there a similar syntax for testing against the value?
The example I have given is a simplification of what I need. In reality there will be more than one test value... returned by another cursor.
DECLARE
CURSOR c_type_id_usg
IS
[Code]....
-- get the list of sms type id usg values
OPEN c_type_id_usg;
FETCH c_type_id_usg bulk collect into l_type_ids;
CLOSE c_type_id_usg;
-- the above returns value 300,301,310,320,400,410
IF l_type_ids.exists(310)
then
dbms_output.put_line('I have found an entry ');
else
dbms_output.put_line('I have NOT found an entry ' );
end if;

I'm working on a plsql program and i'm using collections. I loop the collection and delete rows of it depending on the edits of my program. Here is the question.
if my collection holds
rows

i can simply do something like FOR indx in invoice.first..invoice.lasthowever if i delete row 2 of my collection i get an error. no data found.

how to use collection variables as OUT parameters in procedure.
In PL/Sql, I create a new collection using TYPE. Then populate it with BULK COLLECT.The next step I need is to load data from the collection to pass as WHERE condition to a ref cursor.How I can do this?Every test I did fais. It seems to me that I cannot use some kind of SELECT to retrieve all data from the collection, but I might use a cursor to read row by row. (I'm on Oracle 11gR2 DB )

does this mean, we are having memory crunch for this instance on node 1? we have sga_target=26gb and sga_max_size=32gb set for this instance.
