• Create a simple query (SQL)

  Hi experts,
  
  I have a table with data as follows:
  
  Database version: 10.2.0.4
  Table name: TRANSACTION_HIST_TAB
  

  TRANS_ID      LOT_NO    PART_NO    QTY    TRANSACTION         LOCATION_NO    ROWVERSION
  ---------     -------   --------   ----   -----------------   ------------   ----------------------
  T00000X1      L001     ABC         10     CHANGE LOCATION     WRH_1          01/01/13 08:00:00 AM
  T00000X2      L001     ABC        10     CHANGE LOCATION     WRH_2          01/02/13 10:00:00 AM
  T00000X3      L002     XYZ        20     CHANGE LOCATION     WRH_3          01/03/13 11:00:00 AM

  and I want to create a single query (SQL) which can get data grouped by LOT_NO and only the first transaction by LOT_NO
  
  Expected results:
  

  TRANS_ID      LOT_NO    PART_NO    QTY    TRANSACTION         LOCATION_NO    ROWVERSION

  Hi, Rob.

  Here's one way:

  WITH     got_r_num     AS
  (
       SELECT     t.*     -- or list columns you want
       ,     ROW_NUMBER () OVER ( PARTITION BY  lot_no
                                 ORDER BY          rowversion
                         )  AS r_num
       FROM    transaction_hist_tab  t
  )
  SELECT       *     -- or list all columns except r_num
  FROM       got_r_num
  WHERE       r_num     = 1
  ;
  

  Depending on your data and your needs, match Sub like Manik suggested, might work. I think that you want to GROUP BY lot_no only, no transid.

  I hope that answers your question.
  If not, post a small example data (CREATE TABLE and only relevant columns, INSERT statements), and the results you want from this data.
  Explain, using specific examples, how you get these results from these data.
  Always say what version of Oracle you are using (for example, 11.2.0.2.0).

• Query SQL statement?

  I'm trying to do a COUNT for each time the word "Suspended" appears in a column.
  
  Use: Oracle 10g
  
  Example:
  

  Name                     Comments          
  
  Tim Johnson   Suspended for 1 game
  Tim Johnson   Suspended for 4 games
  Rob Johnson   Suspended for 3 games

  Output should look like

• Capture the SQL statement before it runs

  Hello world
  
  I have a question about the capture of query sql statement in Oracle before he run? Is it possible to do and can give you the answer to this problem? Enter here means I can catch the declaration of all applications (like SQL, I * sqlplus or another application making the request to the database). I want to do this because my teacher asks me to analyze the request and if it violates any policy = > stop before Oracle run it.
  
  I tried this solution
  [Select trigger for Oracle | http://technology.amis.nl/2005/09/26/select-trigger-in-oracle-database-introducing-fine-grained-auditing/].
  but I think he looks not the answer. Because for the audit of the refined, the event handler is called when the first row is obtained. This is the average Oracle a analyze this quere and run to get the first row.
  
  Please help me with this problem

  Hello
  That's what you ask...

  www.Oracle.com/technetwork/Products/Database-Firewall/index.html

  Some other related things are:

  the database Vault control many things related to this in terms of what time of the day and access where data etc.

  Resource Manager can block statements if they want to use too many resources.

  The standard model of privilege/role/grant prevents access you something, that you are not allowed to see.

  Views can hide columns if necessary.

  DTV and RLS can hide lines

  It depends exactly on the requirement.

  See you soon,.

• 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.

• SQL SQL statement generator

  I see a source code for web site developers to use SQL Builder to build about 300 queries to SQL Server, but it can be done by a stored procedure or a group clause in the SQL statement.

  The performance of the web site seems OK,

  I would like to know ColdFusion runs the SQL Server 300 times or he is smart enough to know and convert it to face once the server only once.

  Is there a performance impact ColdFusion or SQL Server-side?

  Your information and your help is much appreciated,

  Kind regards

  My question is that 300 queries can be simplified as a simple SQL as

  Select MyName, count (MyID) from myTable

  where myname = "Name2".

  Group by MyName

  Select MyName, count (MyID) from myTable

  where myName = 'Name3 '.

  Group by MyName

  Maybe a couple of uses as follows

  Select MyName, count (MyID) from myTable

  Group by MyName

  or save it as a stored procedure that the web server or web page only the database server a hit instead of 300 times.

  I would like to know ColdFusion is smart enough to know the SQL are similar and only execute SQL against dabase server.

  In my view, query-of-a-query is a smart enough solution for the problem. In the following example, ColdFusion visits the database only once!

  Select MyName, count (MyID) from myTable

  Group by MyName

  Select *.

  from myQuery

  where myname = "Name1".

  Select *.

  from myQuery

  where myname = "Name2".

  ...

  ...

  Select *.

  from myQuery

  where myname = "Name300."

• Run the second sql statement only if the first sql statement is set to zero.

  Hey guys I seem to have a mental block here. I have two sql statements. I would like to than the second to run only if the first sql statement is set to zero. I know that I can use PLsql but I would really like to see if I can do this with sql upward. Your answers are very much appreciated.
  This is the first sql

  Any help would be greatly appreciated. I tried to accomplish with the case statement but it dosent everything seems to work for me.
  Thank you

  Miguel,

  the idea is simple: join the two queries (via the union of all) and to change the second part as to return only the rows if the first query returns no rows by changing the NOT EXISTS (first request). Hope I made it clear... ;)

• Using a Bind Variable in the FROM of a SQL statement part?

  Hi all
  
  I have a problem, I am trying to execute a SQL statement. However, I need the FROM part of the SQL statement in a variable binding. This is because the end user will have to choose between 2 views of database.
  
  I tried this:
  Select CON_ID from: P23_DB_NAME where CON_LEGACY_ID =: P23_CONLEG_NO
  
  I had no chance. The error I got was,
  '+ The query cannot be parsed in the generator. If you believe that your request is
  syntactically correct, choose the generic "columns" box below the
  the source of the region without analysis.
  "ORA-00903: invalid table name +".
  What makes sence, but now I'm a little stuck.
  
  Does anyone have ideas for a workaround?
  
  Thanks in advance.
  -N.S.N.O.
  

  The example I gave you is quite simple. You must take some time to study it to see where you need to be very careful what put you where. Now, of course your example does not work becaues you have several errors. It will work for you:

  DECLARE
     x   VARCHAR2 (4000);
  BEGIN
     x := x || 'SELECT CON_ID FROM ';
     x := x || :p23_db_name;
     x := x || ' WHERE CON_LEGACY_ID = ' || :p23_conleg_no;
     RETURN (x);

• 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...

• 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.

  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.

• 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:

  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.
