Select the data from collections plsql

Hi all

I'm not a developer but working as a DBA, so not very familiar with pl/sql, always crossed with documentation and could lead to a solution of my problem. I need advice from expert here.

Problem: I am writing in a kind of special program plsql for surveillance of certain lots, I know that we have much option to do the same db/grid control including... etc but for some
the reason I have to do this, use only plsql.

Requirement: my requirement is to select data in the plsql table and then have the opportunity to ask questions again and again. I prefer not to go to table, rather than directly from plsql...

I wrote below the code for the sample, bulk data in collection type collection and can print using the loop.

Declare
TS type is table v$ session % rowtype index by pls_integer;
tsess ts.
Start
Select * bulk collect into tsess from v$ session;
I'm looping 1.tsess.count
dbms_output.put_line (tsess (i) .terminal);
end loop;
end;
/

But is it possible same collection (tsess in the example above) can be queried using a select as ' select * from table (Tsess) "I searched the net and found this can be done using create type at the database level.» But my problem is that I can't create any object in the database as being it's a production one.

I was looking as if is it possible even can be accomplished... as cast / multiset... However, I could not get it through.

your help would be appreciated!

Kind regards

I don't think you should use the tables here, only SQL, take a look at the factors of subquery and will indicate if it is not enough...

Published by: BrendanP on February 12, 2012 03:07 for an example:

I understand you want to "Refresh" of data that you already have the database purely to be able to use the SQL such as ORDER BY in multiple ways. Here's how you can do it in the original SQL for a particular example, where you query v$ sql time control processor and disk reads separately (I tested it but the result won't be good look here, so omitting it):

WITH v AS (
SELECT
    Substr (sql_text,1,500)             sql_text,
    cpu_time/1000000                    cpu_seconds,
    disk_reads,
    buffer_gets,
    executions,
    CASE WHEN rows_processed != 0 THEN Round( buffer_gets / Nvl (Replace (rows_processed, 0, 1) ,1)) END Buffer_gets_rows_proc,
    Round (buffer_gets / Nvl (Replace (executions, 0, 1), 1)) Buffer_gets_executions,
    elapsed_time / 1000000              elapsed_second,
    module
FROM v$sql s)
SELECT
    'CPU'                order_by,
    cpu_seconds          order_val,
    sql_text,
    cpu_seconds,
    disk_reads,
    buffer_gets,
    executions,
    buffer_gets_rows_proc,
    buffer_gets_executions,
    elapsed_second,
    module
FROM v
 UNION
SELECT
    'Disk reads',
    disk_reads,
    sql_text,
    cpu_seconds,
    disk_reads,
    buffer_gets,
    executions,
    buffer_gets_rows_proc,
    buffer_gets_executions,
    elapsed_second,
    module
FROM v
ORDER BY order_by, order_val DESC

Generic procedure to load the data from the source to the table target

Hi all

I want to create a generic procedure to load data of X number of the source table to X number of the target table.

such as:

Source1-> Target1

Source2-> Target2

-> Target3 Source3

Each target table has the same structure as the source table.

The indexes are same as well. Constraint are not predefined in the source or target tables.there is no involved in loading the data from the business logic.

It would simply add.

This procedure will be scheduled during off hours and probably only once in a month.

I created a procedure that does this, and not like:

(1) make a contribution to the procedure as Source and target table.

(2) find the index in the target table.

(3) get the metadata of the target table indexes and pick up.

(4) delete the index above.

(5) load the data from the source to the target (Append).

(6) Re-create the indexes on the target table by using the collection of meta data.

(7) delete the records in the source table.

sample proc as: (logging of errors is missing)

CREATE or REPLACE PROCEDURE PP_LOAD_SOURCE_TARGET (p_source_table IN VARCHAR2,

p_target_table IN VARCHAR2)

How to insert into a GLOBAL TEMPORARY TABLE and get the data from it?
The requrement is
Split the string ENTRY point on the base and store it in a Collection. And the values of the collection will be stored in a global temporary table. Then, I'm updating some other table based on the data from the temporary table.

There is in fact no error message. But there is no data in the temporary table and also no change in the update statement

First of all, I'm creatiing a global temporary table only once outside the procedure.

CREATE GLOBAL TEMPORARY table GLt (data_element number)

create or replace procedure test_proc (p_in_string VARCHAR2) is
i the number: = 0;
number of POS: = 0;
CLOB lv_str: = p_in_string;
p_delim VARCHAR2 (1): = ', ';

TYPE t_array IS TABLE OF VARCHAR2 (20) INDEX directory.
t_array channels;

BEGIN

-cutting of string input and store in the strings (i) collection

POS: = instr (lv_str, p_delim, 1, 1);
WHILE (pos! = 0) LOOP
i: = i + 1;
Strings (i): = substr(lv_str,1,pos-1);
lv_str: = substr (lv_str, pos + 1, length (lv_str));
POS: = instr (lv_str, p_delim, 1, 1);
IF pos = 0 THEN
Strings (i + 1): = lv_str;
END IF;
END LOOP;

run immediately "drop table TWG;
run immediately ' CREATE GLOBAL TEMPORARY table (data_element number) TWG on commit preserve rows ";

FORALL i in strings.first... Strings.Last
INSERT INTO VALUES TWG (strings (i));
commit;

Update first_tbl set PIN is "XXX" where first_col in (select data_element from TWG);.
commit;

END test_proc;

Remove the two execute immediate line. They are wrong.

And then use the table in your code that you created at the beginning. The name is GLT.
And delete the first commit. This validation would empty the temporary table of GLT.

You get an error? Or it does not work as expected?

Also, show how you call the procedure.

How can I get the data from a range of AutoFilter in Excel?

I have a spreadsheet with a large number of lines (5000) where I want to extract data. I have opened the workbook successfully, configure an automatic filter and filtered the data to select the data corresponding to the criteria using the nodes property of the ActiveX Excel object and invoke. I now have to enter the selected data in a table for later processing, and this is where I am stuck. Help Excel online seems to suggest the creation of a Range object by using special cells with the xlCellTypeVisible type. If I Range.Count I get the right number of cells, but Range.Value2 produces a variant which contains only the first block of data (a beach filtered automatically seems to consist of several non continuous blocks). Anyone know how I can read the contents of the range in an array of strings?

Thanks in advance

Ken

IT SOLVED!

Found a calling areas of property which returns a collection of the areas of each of them continues a range object. Simply cycled through these areas using the earlier technique, build the table I want. See below

Select the data in a table and update in another table

Dear experts,
create the table TB_ENCRYPT
(
Identification number,
Varchar2 (200) KEY
);
INSERT INTO TB_ENCRYPT VALUES(1,'HJUVHDUIFBSDGVU');
SELECT * FROM TB_ENCRYPT;
1 HJUVHDUIFBSDGVU
create TABLE users)
username, NUMBER of
password VARCHAR2 (200)
);
Insert users
values (1, 123 # "")
Insert users
values (2, 456 #')
Select * from users;
1 123 #.
# 2 456
I want to select the data KEY for table TB_ENCRYPT column and update in the column of tables for the respective key user password
TB_ENCRYPT table contains only a single key value. Comparing this key, I want to update the old value of the key to the new value.
For encryption and decryption I followed the java class method.no is worried about that.
create or replace
PACKAGE PCK_ENC AUTHID CURRENT_USER AS
FUNCTION DECRYPT (VARCHAR arg0, arg1 VARCHAR) AS VARCHAR BACK LANGUAGE JAVA NAME 'Encrclass.decrypt (java.lang.String, java.lang.String) return java.lang.String ';
FUNCTION ENCRYPT (VARCHAR arg0, arg1 VARCHAR) AS VARCHAR BACK LANGUAGE JAVA NAME 'Encrclass.encrypt (java.lang.String, java.lang.String) return java.lang.String ';
END;
SELECT PCK_ENC. ENCRYPT('1234','HJUVHDUIFBSDGVU') FROM DUAL;
HERE,
1234 - is the password of the users table column data
HJUVHDUIFBSDGVU - represents the key of table TB_ENCRYPT column data.
Comparing this key, I want to update the old value of the key to the new value.
I tried with this method
declare
cursor c1 is
Select the key
of TB_ENCRYPT
where id = 1
update the id;
Start
for c1_rec looping c1
update users
password is PCK_ENC. Encrypt (Password, Key)
the location being c1;
commit;
end loop;
end;
/
Help, please

You can use the MERGE statement.
```
merge into users
using tb_encrypt
   on (id = userid)
  when matched then
      update set password = PCK_ENC.ENCRYPT(password,key);
```
And why you encrypt your password. This isn't a good idea. Just password hash.

How can I get the data from the drive of barcodes to forms

Hi Experts,
Forms 6i
I would like to collect data from the barcode scanner.
No idea if you got it please share.
Thanks in advance.

Hello

I think that his works even as the keyboard. You type the code manually or you can read it from a scanner. With the help of the keyboard that you can able to type what anyone on the position of the cursor, in the same way the barcode scanner also works. Just like a copy and paste the scanner copies the data from the physical device and paste it into your corrent cursor position. There is no separate program encodings necessary for this work.

SELECT the data inserted into a global temporary Table in a stored proc
A stored procedure is run from Oracle SQL Developer to insert data into a global temporary table. A SQL (in Oracle SQL Developer) worksheet is open to run a SELECT query to retrieve the data from the temporary table overall which was populated in the stored procedure. No row is returned. I guess it's because the stored procedure and the SELECT statement executed in different sessions.

Is it possible to run the stored procedure in Oracle SQL Developer and then execute a select statement on the temporary table overall which was filled in the stored procedure by using the same connection so that the data can be extracted?

I use version 1.5.1 build HAND-5440 of Oracle SQL Developer.
In a worksheet, do something like

Start
insert_proc;
end;

Select * from my_temp_table;

Place the cursor on each statement in turn and Press f9 (where it all began... the end is a single statement.

I bought an iPhone 6s and want to transfer the data from my old iPhone 4S with iTunes

I bought an iPhone 6s and want to transfer the data from my old iPhone 4S with iTunes but it says "the"iPhone"iPhone cannot be used because it requires a newer version of iTunes. Go to www.itunes.com to download the latest version of iTunes. "

I checked and the version of itunes is the latest AID!

Most likely, what you found, is that the iTunes version is the latest available for your operating system.

The latest version of iTunes is 12.4.3. This version requires at least OS X 10.8.5 or later version, or Windows 7 or later version.

If your iTunes version is earlier than 12.4.3, it will probably not recognize your 6s performance iPhone iOS 9.

If you do not have the required operating system, get first. Then download from iTunes

Unable to delete the data from the Safari Web site...

Hello.

I need help with my Safari browser on my Mac.

Im trying to remove all Web site data with the following procedure:

Safari-> Preferences-> privacy-> Remove All Data Web site...

His does not work. Before clicking on the button I have 108 Web sites stored cookies or other data, I click the button, and nothing happens... I'm still 108 cookies.

I also did the following:

. - activate the Menu developer and Cache empty and tried again... nothing

. - used CleanMyMac v3 and it says I don't have cookies.

. - order iCloud Sync of Safari on the computer and try again... same problem

. - removed manually com.apple. Safari. Secure

Any help will be great. Please let me know if you need any additional info.

Thank you.

Hello DZanvettor,

Thank you for using communities of Apple Support.

If I understand your message that nothing happens when you try to remove the Safari Web site data. I know how it is important for you to be able to remove the Safari Web site data. I recommend that you restart your Mac into safe mode and see if you can remove the data from the Web site in secure mode.

Here are the steps to restart your Mac in safe mode:

Safe mode (sometimes called secure boot) is a way to start up your Mac so that it performs certain checks and prevents certain software from loading automatically or opening.

From your Mac in safe mode does the following:

* Check your startup disk and attempts to fix problems if necessary directory
* Loads only required kernel extensions
* Prevents the elements start and the login items open automatically
* Disables installed user fonts
* Delete font caches, hiding the kernel and other files of the system cache
* Together, these changes can help resolve or isolate issues related to your startup disk.

Follow these steps to start in safe mode.

1. start or restart your Mac.
2. as soon as you hear the startup tone, hold down the SHIFT key.
3. release the SHIFT key when you see the Apple logo appears on the screen.

After you delete data from the Web site in safe mode restart your Mac and allow it to start up as usual. Then test the issue again.

Best regards.

Hi I want to erase all the data from my current phone if I erase content and settings would be deleted all the data off my sim card? Thanks for your help

Erase the data on your phone will not erase the data on the sim card.

If I remove all the data from the Web site it will also remove all my passwords?

If I remove all the data from the Web site it will also remove all my passwords?

It will not erase your saved in the Keychain passwords, but you need to connect back to all Web sites (like this one) that require you to log in.

Extract the data from the ReadyNAS Duo 3 to disk?

Hello

I have a ReadyNAS Duo chassis crashed with two drives of 3 TB in it. Both discs seem to work very well.

How can I do to retrieve the data from disks of theses? they were in a RAID 1 configuration, so I guess I just need to extract one of the disks. Does it matter which drive is it?

I started to connect one of the disks to an installation of Ubuntu and I can find from the disc with respect to the available partitions, but I get no info on the file system used, only that it is flagged as RAID.

Because I don't want ot destroy all the data I was very careful when working with the partitioning tool. So far, I've installed and looked parted, gparted, gdisk and a few others.

Since I'm really new to Linux, I need more detailed assistance with indicators to be used to access the drive.

Any input is highly appreciated.
