• Question of SQL statement

  I have this PreExpression at a stage of SQL statement:

  Locals.SQL_LatestResult = "SELECT UUT_RESULT.ID, UUT_RESULT. UUT_SERIAL_NUMBER, UUT_RESULT. START_DATE_TIME UUT_RESULT WHERE (((UUT_RESULT. UUT_SERIAL_NUMBER) =------"' + Locals.serial + ' \ ') AND ((UUT_RESULT." START_DATE_TIME) = (SELECT MAX (UUT_RESULT2. START_DATE_TIME) OF UUT_RESULT AS UUT_RESULT2 WHERE UUT_RESULT. UUT_SERIAL_NUMBER = UUT_RESULT2. UUT_SERIAL_NUMBER))); »

  Locals.SQL_LatestResult has this value after the PreExpression:

  SELECT UUT_RESULT.ID, UUT_RESULT. UUT_SERIAL_NUMBER, UUT_RESULT. START_DATE_TIME UUT_RESULT WHERE (((UUT_RESULT. UUT_SERIAL_NUMBER) = "15514011") AND ((UUT_RESULT. START_DATE_TIME) = (SELECT MAX (UUT_RESULT2. START_DATE_TIME) OF UUT_RESULT AS UUT_RESULT2 WHERE UUT_RESULT. UUT_SERIAL_NUMBER = UUT_RESULT2. UUT_SERIAL_NUMBER)));

  I get the number of records = 0, if I run the sequence.

  If I copy the exact same SQL query in access I get what I want to know a record.

  If I remove that part of the query:

  ((UUT_RESULT. UUT_SERIAL_NUMBER) =------"" + Locals.serial + "\") "

  I get 388 records which is correct and it run directly in access.

  What's not here?

  I was too fast for this post... it's my fault, the database link was wrong, so data were there...

  Statements are very good!

• With the help of a number variable in a SQL statement

  Hello

  I am trying to use a variable in a sql statement, and I ran into problems when the variable is a number. The following line of code works if the variable is a string, but not if it is a number.

  "SELECT PAGE 1 UUT_STATUS OF UNIT_UUT_RESULT WHERE UnitID = '" + Locals.LocalUnitID + "' ORDER BY DESC START_DATE_TIME.

  Is there a difference in the use of single and double quotes and the sign for numbers variables +?

  Thank you

  Stuart

  Jervin is almost correct in the post above.

  While it is correct that numbers in SQL are not enclosed in single quotes ('), we still need the entire expression to a string.  If Locals.LocalUnitID is stored as a number to TestStand, you will need to cast to a string so that the string concatination works properly.

  I believe that the correct form is as follows:

  "SELECT PAGE 1 UUT_STATUS OF UNIT_UUT_RESULT WHERE UnitID ="+ Str (Locals.LocalUnitID) + 'ORDER BY DESC START_DATE_TIME'

• Game of demand does not pick up the good period open to active fixed from the SQL statement

  Hello

  We have a demand that could kick off the simultaneous application of the value: Ixr: list of asset by period and Ixr: reserve book report.

  
  

  ON overall demand, we set the parameter: default period based on a SQL = select period_name from FA_DEPRN_PERIODS where book_type_code = 'PER2011' and period_close_date is null

  
  

  The query runs with the good period, until we open the new period, the game application will still come closed period.

  When I run this script on the database, it gives the correct name of the open period.

  
  

  Why all the demand does not pick up the open period?

  Hello

  When planning, the parameter values that you gave when planning will not change.

  For the test, for a simultaneous program, I create a parameter and has given the value 100 tank and default type sql statement and the value as below.

  Select to_char (sysdate, 'dd-mon-yyyy hh24:mi:ss') of double

  If, at the time of the program, it shows a default value such as the date and time with seconds. Then I planned it for every minute.

  When you check in for each race it is seen the first time only, it does not.

  so in your case, you must plan its new after change of period.

  Hope this will help you...

• What are these SQL statements?

  Hello!

  We are our applications running on Windows Server 2003 where it works fine, using Oracle via OCI 12.1.

  Now, we have the application installed on Windows Server 2012 and it works very slowly.

  When comparing these two environments trace files came a surprise: Oracle generates a lot of SQL statements when run on Windows Server 2012!  By operating on Windows2003 it only executes the SQL from the applicaton instructions.  These additional SQL statements must be the reason for the slowness, but why Oracle it generates them and how could we get arrested?

  An example:

  Thank you all for the reply!  This time, the reason was a problem in network traffic (TCP protocol): a lot of retransmissions for a still unknown reason.  If it had nothing to do with Oracle after all.

  I cried for help here because as a common application programmer, I wasn't familiar with the Interior details of SQL analysis and after seeing it in the trace, I assumed that these strange SQL statements - which, for some reason, is appeared only in W2012-trace - were the reason for the slowness.

  Thank you, I'm a little wiser now - and I hope that many others find this thread before asking the same question!

• How can I pass a condition of the table in the sql statement?

  For example, in the table in the COND Varchar2 column (200) there is the value ' VAR > 10'.

  | COND |

  |' VAR > 10' |

  where VAR is the name of the table column. I would like to make statement CASE WHEN VAR > 10 AND 0... I tried with as subquery

  WHEN BOX (SELECT COND FROM TABLE WHERE...) THEN 0, but it does not work.

  Hello

  You can do this by using dynamic SQL.

  that is to say:

  declare
    v_stm      varchar2(4000);
    v_cond      varchar2(100);
    v_result    integer;
  begin
    select cond
      into v_cond
      from yourtable
    where a=1;
  
    v_stm := 'select case when '||v_cond||' then 0 ...';
  
    -- dynamic sql
    execute immediate v_stm
      into v_result;
  
  end;
  /
  

  Remember that, in general, dynamic SQL has a performance degradation that SQL static and should be avoided when possible.

  Storage condition or the SQL statements in the tables is not a good practice.

  Kind regards.

• Identify the SQL statements that are executed frequently

  I would like to identify SQL statements that are executed may times (e.g., > 1000 times) during an interval AWR.

  I am aware of coloring a SQL_ID with exec ('...') dbms_workload_repository.add_colored_sql; but then the SQL ID must be known.

  Is it also possible to do the same for the (not yet known) SQL statements that are executed > 1000 times? I think that the SQL statements that run very quickly (for example 1 s <) won't be captured automatically in a CWA even if those statements are frequently performed.

  This is not unusual. Another app could analyze for example hard the most often used SQLs in upstairs app - making benefit of further processing (in theory) of sweet analysis when you use these SQLs.

  In fact, I remember reading something to this effect as a performance for some factor or another Oracle document or note?

  So unless you have serious questions of shared pool, why bother with these sliders? What would be the problem?

• Order of execution of SQL statements

  Hello

  I have two SQL statements where the first statement executes on a table with more than 40 million lines, the second statement is running on a table more 6 million lines.  When they are running their own each take about 0.15 seconds to run, but when combined they take 20 minutes to run, (the second SQL statement is inserted in the WHERE clause of the statement of first).  It would seem that after combining these statements, the first statement goes through all 40 million lines before it performs the SELECT in the WHERE clause.  I think that what is necessary is to ensure the SELECT in the WHERE clause is executed first... or something like that!  Anyone has any ideas on how to combine these statements but not suffer from the performance impact?

  The first statement is:

  Select csi.instance_id,

  OEL.ordered_item

  of apps.csi_item_instances csi,.

  Apps.oe_order_lines_all oel

  where csi.instance_id in

  (1718000,3698000,48740202)

  and csi.last_oe_order_line_id = oel.line_id;

  The second statement is:

  Select / * + INDEX (IEA (attribute_id)) * /.

  IEA.instance_id

  apps.csi_iea_values do

  where iea.attribute_id = 10004

  and iea.attribute_value is not null;

  The joint return is:

  Select csi.instance_id,

  OEL.ordered_item

  of apps.csi_item_instances csi,.

  Apps.oe_order_lines_all oel

  where csi.instance_id in

  (select / * + INDEX (IEA (attribute_id)) * /)

  IEA.instance_id

  apps.csi_iea_values do

  where iea.attribute_id = 10004

  and iea.attribute_value is not null)

  and csi.last_oe_order_line_id = oel.line_id;

  Thanks for any help,

  Mike

  Your subquery returns probably just two values that you did originally as constants - but the optimizer thinks that you're going to get 564 K lines.  This is why the indicator for the simple query has a beneficial effect, it forces the Oracle to use an index when it would otherwise make a search.

  When the subquery is incorporated, however, the optimizer uses its cardinality expected to decide whether to use a nested loop join or the hash join to CSI_ITEM_INSTANCES, since the large enough estimate, he uses the hash with a join analysis complete.  That's why I pointed out that the fact to tell the optimizer to how many lines outside the subquery should make a difference.

  Have you tried the "common table expression" approach, rather than approach no_merge, but it would not help because it does not change the optimizer for cardinality estimate.  If you want to repeat the method CTE adding boards / * + materialize cardinality (2) * / to the query in the WITH clause, you should get the desired result.

• Copy SQL statement to another database with the same SQL_ID

  Is there a reliable way to copy a sql statement in a database to another preserving the formatting so it ends with the same SQL_ID.

  I want to copy a statement of the shared pool to a test database to develop a plan to import sql database in production.

  In the past, I just did ' select sql_fulltext from v$ sql "in SQL Developer and pasted the result into a spreadsheet SQL Developer and run it.   The statement is now in the pool shared with the correct sql_id.

  This does not work for instruction, I am currently in train.  It ends with a different id of sql.

  I know it's probably a problem of formatting, but the statement is 1000 characters and a manual check will take forever.

  You could put in a SQL Tuning Set and transfer it.

• error in pseudo-column "DECODE" can be used within an SQL statement

  Hi gurus,

  Your help is grealty appreciated. Please help me.

  
  I'm trying to see if I can use the function decode as below and get the error, here below vPlatformfrom value would be QA or MTS

  
  vDataBase1 :='@'|| Decode (vPlatformfrom, 'STD', 'STD', 'QA', 'QA')

  
  Before we check function NVL to a single platform, but now we need the database based on the platform is here.

  -vDataBase1 :='@'|| NVL (vPlatformto, 'MTS');

  Error:

  PLS-00204: pseudo-column "DECODE" or function may be used within an SQL statement

  > So, here, instead of the decode function, I can use this case as below:

  Well... you can, but why?  In your CASE, you simply return the same value as the variable.

  You might as well use: vDataBase1: = vPlatformfrom;  It would reach exactly the same thing.

  If vPlatformfrom can be a null value, you will need to decide what database to use or an exception.  I think you're original code (NVL) were probably more correct, but I can't decide which.

  (and don't bother selecting double, it is an unnecessary sql statement which must be analysed, etc..)

• Vo SQL statement will not use aliases

  Hello!

  When I tried to enter the following code in the SQL statement in my definition of VO, it gave me an error in column ambiguously defined:

  SELECT a.PERSON_ID,

  a.EFFECTIVE_START_DATE,

  a.EFFECTIVE_END_DATE,

  a.EFFECTIVE_START_DATE,

  a.EFFECTIVE_END_DATE,

  a.EMPLOYEE_NUMBER,

  a.FULL_NAME

  OF PER_ALL_PEOPLE_F one

  I need to put an alias because I need to refer to one of its columns inside the place where the condition. What is supposed to be the right way to set it?

  Thank you.

  whatever the dynamic where clause you add with setwhereclause, it is added on top of the query you mentioned in the original Version, so your alias doesn't work

  Now if you look at the care of error fully you can see you are querying VO got closed in support () and another alias has been given by the framework (OAF) so all adding the whereclause by setwherelcause dynamically delete pls the 'a'., of the Sub statement

  setWhereClause ("a.employee_number =: 1 and a.effective_end_date = (select max (effective_end_date) in the per_all_people_f where employee_number = a.employee_number) '");

  ratther write like

  setWhereClause ("employee_number =: 1 and effective_end_date = (select max (effective_end_date) in the per_all_people_f b where b.employee_number =: 2)" ");

  setWhereClauseParams (null); Always reset

  setWhereClauseParam (0, EmpNumber);

  setWhereClauseParam (1, EmpNumber);

  I hope that is clear, if not please let me know.

• Try to run a SQL statement through the window of OEM 12 c run SQL.  Statement fails

  All,

  I have a 11g database.  When it is initially installed, I installed it in $ORACLE_BASE = / orabin/app/oracle/product and $ORACLE_HOME = $ORACLE_BASE/11gDB_R2.  This is the version 11.2.0.1 to give birth to 11.2.0.3.

  Recently, I installed 11.2.0.4 in $ORACLE_BASE/11.2.0.4.  Then, I upgraded my database at 11.2.0.4.  Everything works fine.

  All my scripts on the linux host logon changed to point my environment at $ORACLE_BASE/11.2.0.4 House and my $PATH when I connect to the linux host is: /orabin/app/oracle/product/11.2.0.4/bin:/orabin/app/oracle/product/11.2.0.4/OPatch:/sbin:/usr/kerberos/bin:/usr/local/bin:/bin:/usr/bin:/home/oracle/bin

  On my OEM Console, the database appears as 11.2.0.4 and me can manage very well.

  However, when I try to use the window of the OEM Console to execute SQL to execute any type of SQL statement, it fails.

  The failure error is:

  Could not launch/orabin/app/oracle/product/11gDB_R2/bin/sqlplus-s/nolog: no such file or directory

  It would be a mistake since the 11gDB_R2 directory tree (the 11.2.0.3 software) has been removed from the host, now that the database is set to level and working as 11.2.0.4.

  I wonder if somewhere in the OEM software, there is always a pointer to the old ORACLE_HOME?  I can't find anything in the .bashrc or other shell scripts that are executed when a Shell session on the host computer which were still the reference to the old directory of 11gDB_R2 so I'm a bit puzzled.

  I have 8 guests, and all have been improved in the same way at 11.2.0.4.  For some databases, the OEM window run SQL is executing the SQL code.

  Someone has some ideas on this?

  Go to the Configuration of the analysis of the database (when you set the password) and update of the Oracle home.   Also do this for all targets listener on this host as well.
