• SQL execution order

  Hi friends,

  Reference post https://community.oracle.com/thread/3520158

  This means SQL executed in different order, or there is some reason to get error in that order?

  Hello

  Kimmy says:

  HI Frank and Baris,

  Is that means there is a defined order for execution of SQL to oracle but compiling the SQL statement has no order defined by the (FROM, WHERE, GROUP BY) clauses and compilation may give error in any order, and which will compile all first does matter?

  Kind regards

  The system can choose to compile an SQL statement in any order.  I have never seen a case where this order is significant to anyone.  (I don't know what is important to you.)

  If your code has compile errors, you will get only 1 error message, and the message can be caused by any line of your code.  If your SQL statement has 10 lines, and you get an error message referring to line 5, there may be other errors as well.  If there is another error, could be on lines 1-4, or it could be on lines 6-10, it could be elsewhere on line 5.

  There is a relationship between the clauses in your code and the order in which the code is run.  For example, the compiled code corresponding to a condition of a FROM clause join will probably run before the compiled code corresponding to the ORDER byclause of this request.  The rules specifying the 'order' can be useful, but should not be taken too literally.

• Oracle SQL execution order issues, I how to solve this problem in OBIEE. My god.

  I create the model of business in administrative tools, the model along with below sql (viewA and viewB both are seen):

• v$ SQL.elapased_time &gt; 0 and v$ sql.executions = 0-&gt; does this mean?

  Hello. all.
  
  that means in the dictionary of v$ sql (10.2.0.4)
  
  v$ SQL.elapased_time > 0
  v$ SQL.executions = 0
  
  Best regards.

  The statement has been analyzed (or it would not have been in v$ sql), but it was never executed.

  Some drivers ODBC and other front end tools seem to require additional analysis.
  You do not provide any other context (as affected for example instruction) a more precise answer is difficult to predict.

• PL/SQL execution error Question

  Hi Experts,
  It's the SQL procedure I remove a set number of order that are closed
  
  CREATE OR REPLACE PROCEDURE closed_test1 (varchar tabname, v_rowcount_int certain NUMBER)

  It's the way you need to call the procedure.

  DECLARE
    v_rowndel   NUMBER;
  BEGIN
    closed_test1 ( 'COST_TRANS_TABLE', v_rowndel);
    DBMS_OUTPUT.PUT_LINE ('v_rowndel = ' || v_rowndel);
  END;
  

  If you use a tool, then turn on dbms_output.
  If execution of sqlplus and then SET SERVEROUPUT on.

• SQL sort order?

  When installing UCCE I use the ICMDBA to create the base of data but get this error:

  "The sorting order of SQL Server on this computer is not binary. You can't go any further.

  Anyone know how you can change the SQL sort order?

  Hello

  To change the SQL Server "Binary order", you will need to reinstall SQL Server and select 'Custom' config Binary order (Latin1_General) for installation.

  Follow the instructions in this link:

• Test suite execution order

  Hi friends,

  I need to run a Suite of 5 tries. I created a Suite with these 5 trials. Trials are appearing in alphabetical order. When I run it, it runs in a random order (not included).

  I want to run it in the order indicated (for example, Test_3, Test_2, Test_4, Test_1, Test_5). How can I achieve this?

  Thanks in advance!

  Hi James,

  Thanks for the clarification.  I could be wrong, but I do not believe there have been complaints on test item out of sequence - that is, there is a SEQUENCE column in the SUITE_ITEM table in order to control the order of execution of test in the suite.  If you run a query similar to the following in a worksheet (or as a user-defined report) against your unit test repository, the execution order corresponds to the order of the sequence columns?

  SELECT UT_SUITE.NAME AS NOM_SUITE,

  UT_TEST.NAME ACE TEST_NAME,

  UT_SUITE_ITEMS. SEQUENCE,

  UT_SUITE_ITEMS. RUN_START,

  UT_SUITE_ITEMS. RUN_TEAR

  OF UT_SUITE_ITEMS

  JOIN INTERNAL UT_SUITE

  ON UT_SUITE_ITEMS. UT_SID = UT_SUITE. UT_SID

  JOIN INTERNAL UT_TEST

  ON UT_TEST. UT_ID = UT_SUITE_ITEMS. UT_ID

  ORDER OF NOM_SUITE, UT_SUITE_ITEMS. SEQUENCE;

  In any case, the point of confusion is perhaps alphabetical list of tests in a suite does not expose the order of creation (sequence).  So if I have...

  1. create 10 tests: test_0, test_2,..., test_9

  2. Add all to suite_1 in ascending order.

  3. run the above query.  It shows the sequence numbers the suffix of test matches

  4. remove the tests with a numbered suffix even.

  5. Add in trials with pairs suffixes, but in descending order.

  6. run the above query.  He then shows the tests, in the order 0,..., 9, as tests_ 1, 3, 5, 7, 9, 8, 6, 4, 2, 0

  Who help me?   I guess listing tests in a suite in the order of creation (sequence) and allowing to make drag & drop reorganization could be more intuitive.

  Kind regards

• SRM + SQL + 3rd party replication and suspend the DB

  Gentlemen

  What can the SRM to ensure customers a SQL VM running on (and replicated by) 3^rd party storage is applied consistently? The HP SRA has code that can invoke the suspension in the virtual machine? Or is there some kind of way scripted as part of SRM, that a quiesce DB in the virtual machine can be triggered in tandem with or just as a LUN replication occurs?

  I know that HP is responsible for the ASR - but in these situations, we sometimes get caught between vendors. Looking for experience "How have any other mission critical SQL resources protected using 3PAR and SRM".

  In other words:

  We are looking for assistance with a DR implementation for a specific application of SQL. The app is on virtual machines running on 3PAR storage. We bought all the necessary "3PAR suite application licenses" and then also have VMware SRM.

  We are more concerned than LUNS replicated DR on-site production (LUN will be virtual computers hosting SQL data storage I assume) will be fully SQL-compliant (i.e. better than crash-consistent), during replication.

  We have some experience with 3PAR replications - but to my knowledge have not yet worked with the application suites.

  Question - anyone can describe what role (if any) suites of applications 3PAR can have in correctly the suspension SQL running on a virtual machine that is on a LUN 3PAR? I don't know we can do this medium - seems that we will have to use RDM (or vVOls if they are compatible SRM) be properly suspended the DB. Is there a HP storage agent that can run on a VM SQL in order to coordinate with the table when the underlying LUN snapshots are performed?

  You are right. Consistency in the application will have to be managed at the level of the array. Some providers of table (I know NetApp specifically) offer the ability to place an agent on the VMS and this agent to use the table to ensure uniformity in the application, I'm not sure of HP.

  Another option that you might look at is vSphere replication. VR offers quiecing VSS (with JEREMIAH) in native mode.

  If you are looking for a specific response to the use of replication 3PAR application suites I suggest you post to a forum of HP. vVOLs are not yet compatible with SRM and I do not see how RDM you will get what you are looking for.

  Finally, how you deal with your post, I would say that you do not assume that only men participate in this forum.

• SQL execution time

  Hello

  I was wondering if anyone could advise on the best way to capture the following in an 11g database.

  Say that we have;

  -a piece of SQL execution by up to 50 times per minute.

  -unique execution times vary.

  Aside from dba_hist_sqlstat and generate a sort of average over a period of 30 min.

  What would be the best way to get the execution time of this piece of SQL in real-time.

  say I want the individual execution time of this last of 100 executions.

  Any help would be appreciated

• Get the SQL execution plan that is currently running in 9i

  Hello
  
  Apologies for the magnitude of this issue, but I was wondering if someone could help me to the more accurate/efficient way to get a piece of running Oracle 9i SQL execution plan.
  
  in 10g and 11g of course dbms_xplan.display_cursor (sql_id) can be used.
  
  How can this be achieved in 9i, currently I am just get the SQL_TEXT and then executing a plan to explain ("EXPLAIN PLAN for.") - I think that this is not neccesserally the same plan to explain that will be used for the sql code that runs if
  
  Any help would be appreciated.
  
  Thank you

  The plan exists after analysis difficult.
  Statistics of actual execution will require a completed.
  That is why sql followed in real time is so great in 11g.
  In 9i, difficult.

• Number of SQL executions

  Hello...
  I know that this is not related to SQL Developer correctly...
  My problem is that a task will take too much time to complete... I want to see if my sql is executed more then once an instance before it is run only once...
  Threre are several reports in sqldev which are useful (especially the Top SQL by...), I wander if this is a way to reset the account for the number of executions as a normal user for a sql id...
  Thank you very much

  No, you can't do it. These counters are the instance to the scale and cannot be "reset". Not even by a SYSDBA.

  You will need to "snapshot" the values just before starting your work, so that you can subtract those values at the end of your work.

  Even the best option would be to sql trace your work and see exactly where the time went and who and how many times, the SQL statements have been executed.

• More than 1 SQL query with checkbox and error invalid number report

  Hi all

  I have two SQL query reports that each has an apex_item.checkbox and two processes for each report.  A report/process works very well.  It gives me an error of invalid number.

  In addition, another query SQL (editable report) gives me the following error when using the Multi line process, delete.

  	ORA-06502: PL/SQL: digital or value error: character number conversion error ORA-06502: PL/SQL: digital or value error: character number conversion error
  Ok

  When I got a report from SQL query (with box and a process) and the query SQL (editable report) everything worked.  It stopped working when I added another SQL query report (with box and a process).

  A SQL query has the following in my query: apex_item.checkbox(3,email_id,'UNCHECKED') ""

  The other SQL query has the following: apex_item.checkbox(2,b.file_id,'UNCHECKED') ""

  Any help will be greatly appreciated,
