simultaneous immediate execution of multiple instructions?

are there techniques to call execute immediate instructions so that they could run simultaneously without waiting than the previous ones (can be different "background", in sessions but at the same time)?

for example if I write:

declare
  stmt_1 varchar2(100) := 'update ... 1 .. ';
  stmt_2 varchar2(100) := 'update ... 2 .. ';
  ...
  stmt_n varchar2(100) := 'update ... n .. ';
begin
  execute immediate stmt_1;
  execute immediate stmt_2;
  ...
  execute immediate stmt_n;
end;

stmt_1 runs first, then stmt_2 and so on. is there a technique to rewrite it so that these statements would be sent for execution without waiting for the other, IE. Here stmt_2 Wouln't expect stmt_1 finish, stmt_3 for stmt_2 etc. I know autonomous operations, but I have no idea if they could be included as well as some other techniques (if any).

I'd appreciate any advice if this scenario can be coded somehow.

Thank you

You can use something like DBMS_SCHEDULER program each of them as to the work to be performed immediately. Schedules would be started one after the other, but each calendar can be made without waiting for the other end.

There is also the DBMS_PARALLEL_EXECUTE (http://docs.oracle.com/cd/E11882_01/appdev.112/e25788/d_parallel_ex.htm#ARPLS67330) package which is another option.

The execution of multiple instructions after another

Guy Helle!

I was wondering if it is not possible to execute multiple instructions in a line using the Oracle SQL Developer! Impossible to find info on this!

I have the code as the following statements and about 200:

INSERT INTO TBL_MATRIX ("Baumart", "9110", "9110.M", "9110.1", "9110.2", "9110.3", "9110.4", "9111", "9130", "9130.M", "9130.1", "9130.2", "9130.3", "9130.4", "9131", "9140", "9150", "9150.15", "9151", "9152", "9160", "9170", "9180", "9190", "91D0", "91D1", "91D1.3", "91D2", "91D3", "91D4", "91E0", "91E0.A", "91E0.S", "91E0.11", "91E0.12", "91E0.13", "91E0.14", "91E0.15", "91E1", "91E2", "91F0", "91T0", "91U0", "9410", "9410.15", "9420")

Instead of running each query individually, there must be a way to each of them running automatically. Same SQL Server has this feature!

Any advice you can give me?

Kind regards

Hello

You should ask this to the [SQL Developer Forum | http://forums.oracle.com/forums/forum.jspa?forumID=260].

Just a quick thought. I think in SQL Dev, you have two options. 1. performance and 2. Run the Script (near the run iconic button).

Copy all the instructions in the editor and click the iconic run the Script instead of the Run iconic button.

SQL dynamic immediate execution
Hi all

We have a table where we keep the query that will be executed and using bind variables.

But im facing some problems when I try to use it in immediate execution.

guess

function validate is
varaux varchar2 (200);
Start
for r1 in (select query,
using_bind
from table_1) loop
run immediately r1.query in varaux using r1.using_bind;
Return varaux;
end loop;
Returns a null value.
end;

I know that's not the way to do it, but can you give me instructions in the topic...

Thank you
Bruna

No - the problems you are experiencing are because your function uses invalid syntax. The problems have NOTHING to do with 'run immediately '. This works for me and no changes have been made to the dynamic part.
```
create or replace function fn_validate return varchar2 is
varaux varchar2(200);
begin
for r1 in (select 'select ename from emp where empno = :1' query,
7369 using_bind from dual) loop
execute immediate r1.query into varaux using r1.using_bind;
return varaux;
end loop;
return null;
end; 

declare
 myVar varchar2(200);
begin
 myVar := fn_validate();
 dbms_output.put_line(myVar);
end;

Execution of multiple user profiles does not not in Firefox 32.0.3

Hello.

I have several profiles user for work and private use. Today I decided to use Firefox for private use again (currently using Chrome for private use). Because on Chrome, the video is "pixelated" when video quality is superior to 720 p. Also for purposes of stability, if Firefox crashes, which happens frequently, I keep everything.

In any case, I use the Profile Manager for execution of multiple user profiles.

The problem is when I try to open a private profile when you're already running a work profile, it opens a new window of work profile, not a private.

I use this shortcut: "C:\Program Files (x 86) \Mozilla" P - by default - noremote
The "default" profile is the work, I have a different shortcut, which is private:
"C:\Program Files (x 86) \Mozilla ' private Pei - noremote

Any help will be much appreciated. Thank you.

Changing table via the package with immediate execution (problem)

Hello
I have a unusual problem. I have a package that contains the procedure that via execute immediate statement, creates a table on which he performs different actions for example:
-alter table some_owner.dummy_table noparallel
-create index some_owner.idx_name on some_owner.dummy_table (column)...
But I only managed to run move and create synonym table/public via execute immediate statement. Actions as alter table and create index fails with error ORA-01031: insufficient privileges.
Note If call these commands outside the package (a simple script) this all done OK.
I found a way, where I set the AUTHID CURRENT_USER command create package statement. In this way all the actions executed OK.
I wonder why I can't change the table via the package with immediate execution on a table that is in the tablespace "SOME_TABLESPACE" and the title of owner "SOME_OWNER", without putting the AUTHID command on the package.
There must be a problem why a package cannot change the table which is owned by the user 'SOME_OWNER '.
All useful responses would be appreciated.

I have a unusual problem.

No - you don't have. This question has been answered SEVERAL times on this forum and others.

But I only managed to run move and create synonym table/public via execute immediate statement. Actions as alter table and create index fails with error ORA-01031: insufficient privileges.

OK - your username doesn't have privileges to do these operations or only received privileges through roles.

Roles are DISABLED in named PL/SQL blocks that use of the AUTHOR's rights.

Note If call these commands outside the package (a simple script) this all done OK.

I found a way, where I set the AUTHID CURRENT_USER command create package statement. In this way all the actions executed OK.

Of course - the roles are NOT disabled in named PL/SQL blocks that use the rights of the APPELLANT or in anonymous blocks.

I wonder why I can't change the table via the package with immediate execution on a table that is in the tablespace "SOME_TABLESPACE" and the title of owner "SOME_OWNER", without putting the AUTHID command on the package.

Well now you know!

SQL all (and all the anonymous PL/SQL blocks) are analyzed by Oracle as a SQL cursors. These cursor structures are stored in the Shared Pool in the SGA (shared memory area which are essentially the "brain" of the database instance).

Once a cursor was created for a statement SQL, how to use and interface with this SQL cursor on the server (from the point of view of the customer)?

We use on the client side, a calling interface (or API) that allows our code to interact with this SQL cursor on the server. This interface can be ODBC. Or BDE. Or ADO. Or many other 3-4 letters for database interfaces.

PL/SQL is also a language of 'customer' from a SQL perspective. Such as Java and c#, the code PL/SQL will be calls to the SQL engine to analyze and create SQL cursors.

Of course, PL/SQL differs in 2 areas. It runs in the process of the Oracle server. It is the neighbour of the SQL engine.

For this reason, PL/SQL is much more perfectly integrated with the SQL than Java or c#.

But even in spite of this integration, you still need an interface in the client (PL/SQL) to interact with the SQL cursor, that you have created. In PL/SQL, there are a number of such interfaces customer.

There are explicit and implicit cursors. And there are sliders DBMS_SQL and reference. And there are implicit cursors created through immediate enforcement.

The difference between DBMS_SQL and immediate execution is therefore a difference in customer language interface. The SQL cursor on the server (in the shared Pool) doesn't know what customer interface is used. He cares not.

Client side, each of these client interfaces to a SQL cursor has a different function. And determines which one to use.

run immediately , it's fast and easy for dynamic SQL, but it cannot be used to determine the structure (called projection SQL) returned by a cursor to Select . So despite the dynamic SQL code, we must always know the encoding of time, just what this slider will return to consume its production.

DBMS_SQL to 'describe' the cursor SQL projection. So, we can create a dynamic Select SQL cursor. We can question its interface describe in order to determine the number, names and the data types of the columns returned. It can be removed these column values dynamically and consume the cursor.

There are therefore a major difference in the two feature sets. Tools for interfacing with the same SQL cursor.

So the main points to remember are:
-all SQL liquidation as SQL cursors on the server
-you have different interfaces in the language of the client to interact with a SQL cursor

++

Your mission as a programmer, if you choose to accept it, is to determine which of these client interfaces is better suited to meet the requirements in your code.

Procedure failed with ORA-01403, associated with immediate execution, captured

This procedure compiles without error. Its purpose is to copy the sequence of one schema to another object. After it failed with ORA-01403, I added exception code of capture (see the comments in the code).
A few notes:
1. I started the proceedings with exec copy_sequence ('ADDRESS_SEQ', 'SST', 'TEST1');
2. the first sql string is built correctly since I can see in the console output:
Select last_number in the all_sequences where sequence_owner = upper('TSS') and upper('ADDRESS_SEQ') = sequence_name
I can run this SQL command, and returns a real value;
Here is the procedure
SET SERVEROUTPUT ON;
create or replace procedure copy_sequence (seq VARCHAR2, prod_schema VARCHAR2, VARCHAR2 test_schema)
as
Val number (21);
s_sql varchar2 (200);
Start
s_sql: = ' select last_number in the all_sequences where sequence_owner = upper('''|| prod_schema ||'') ') and sequence_name = upper('''||) Seq | " ')';
-immediate' select last_number in the Vale of all_sequences where sequence_owner = upper('''|| prod_schema ||'') ') and sequence_name = upper('''||) Seq | " ')';
Dbms_output.put_line ('sql 1 ' | s_sql);
execute immediate s_sql in val; ---!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! The code does not work here!
Dbms_output.put_line ('val' |) Val);
s_sql: = 'delete the sequence'. test_schema |'. ' || FF.;
Dbms_output.put_line ('sql 2 ' | s_sql);
-execution immediate s_sql;
s_sql: = 'create the sequence'. test_schema |'. ' || Seq |' minvalue maxvalue 1 999999999999999999999 begin by ' | Val | 'increment of 1';
Dbms_output.put_line ('sql 3 ' | s_sql);
-execution immediate s_sql;
-Add the following after procedure thown ORA-01403: no data found
exception when TOO_MANY_ROWS then DBMS_OUTPUT.put_line ('TOO_MANY_ROWS error');
When NO_DATA_FOUND then DBMS_OUTPUT.put_line ('error NO_DATA_FOUND');
While some other then raise_application_error (-20011, "Unknown Exception in this procedure");
end;

??? There is nothing special about SYS or SYSTEM in what concerns them stored procedures. SYS by default is granted directly SELECT ANY SEQUENCE, so it does not work for the owner of MS by SYS. SYSTEM is therefore not:

Parallel execution of multiple scripts
Hi all
I understand that aid of parallels that we can achieve the parallel execution of the queries(insert/update/delete).
Question of my today, I would like to know if parallelism can be achieved for the following scenario.

I have a script with an insert select statement and multiple merge statements and a few updates statements all on the same table.
I have to run this script 12 times on the same table, once for each month of the year.
Currently, we run for Jan (where record_date = '201001') commit, then run for February and so on.

Every 12 months can be executed in parallel. One way I can think is to create 12 different scripts and kicking around the opening 12 sessions SQL more (all on the same table).
Is there a better way to do this?

Note: the data for each month will not affect other other data month.

Kind regards
AJ
Creation of 12 different scripts would be a suboptimal solution and a maintenance nightmare. 1 set script and call 12 times with different settings would be a little better.
1 creating a stored procedure with parameters and execute that procedure in the 12 times Planner would be even better, because everything works on the side server only.

Your description is deliberately vague, so the possibility of blocking cannot be excluded.

In case you need help to use UTL_FILE, then this is.

also, about your mistake, "EXECUTE IMMEDIATE lv_v_stmt INTO lv_v_value; DBMS_METADATA.get_dll returns a CLOB.
