• Why I have two different execution plans for the same query on two different servers

  Hello everyone.

  I need your help to solve the problem quickly.

  In a nutshell, we have two servers that have the same version of Oracle RDBMS (11.2.0.4 EE). One of them for purposes of development and another is a production one.

  We have therefore two different execution plans for the same query executed on both servers. The only case of execution is OK and another is too slow.

  So I have to slow down the work of query using the same scheme to explain that young.

• Error in query of the ordered result query contained CFSCRIPT in CF10

  I came across a very interesting error when you perform a query of a query within a CFSCRIPT tag...

  I get a result in withdrawal of a SQL Server stored procedure.  This is a list of metric names (METRIC_ID) and the metric measures themselves.

  I need to pull the METRIC_ID for this outcome, plans to make a JOIN on another query having display and other attributes of formatting for display in a web page.

  The following code runs without error when the query is not ordered:

  var displayDataQuery = new Query();

  displayDataQuery.setName ("joinedQuery");

  displayDataQuery.setDBType ("query");

  displayDataQuery.setAttributes (qry1 = fullMetricsListQuery);

  displayDataQuery.setAttributes (qry2 = arguments.cubeData);

  displayDataQuery.setSQL ("SELECT METRIC_ID FROM qry2");

  var tempResultSet = displayDataQuery.execute ();

  var cubeMetricIDList = tempResultSet.getResult ();

  When I take the same results of exact query of the same stored procedure, but it is controlled by an ORDER BY clause, this statement;

  var tempResultSet = displayDataQuery.execute ();

  get the following error: "value" cannot be converted to a number.»   It is 2 apostrophes, meaning an empty string between 'value' and 'impossible.'

  
  

  Wait, what?  I want to just a list of names metrics, varchars.  Why is there a conversion error...?

  
  

  The error in the end pprovided back to ColdFusion10\cfusion\CustomTags\com\adobe\coldfusion\base.cfc, line 445

  OK, this is where it takes an interesting twist...

  Starting at line 444, in base.cfc, line 445 bolded in red:

  "< cfif sqlType NEQ" "and arraylen (sqlParams) gt 0 >."

  < cfloop index = "i" = "2" to = "#ArrayLen (sqlArray) #" >

  < arraylen (sqlParams) of lte cfif (i-1) >

  < cfqueryparam attributeCollection = "#sqlParams [i-1] #" / >

  < / cfif >

  #getPreserveSingleQuotes (sqlArray [i]) #.

  < / cfloop >

  < / cfif >

  So if I understand correctly, when I have a query, unordered, copy the following code in base.cfc bed the SQL code in displayDataQuery.setSQL ("SELECT METRIC_ID FROM qry2"), but is not when the query is controlled by METRIC_ID... ?

  Oh, wait... the CFDUMP when using an ordered set of data says something else...

  query
  RESULTSET
  CACHING	fake
  EXECUTIONTIME	4
  SQL	SELECT * FROM qry1 ORDER OF METRIC_ID, LOCATION

  I'm a bit confused why the same data in works set ordered, while an ordered set causes this error.

  All useful suggestions or clues would be greatly appreciated!

  Do you mean that the error has occurred without the order by clause?

  Given that the error only occurs with one unsorted data set, I'm a bit confused why you ask this...?

  I've followed your suggestion:

  Run the same code, but use the cfquery instead of cfscript tag. The error persists there?

  My assumption was that your suggestion is to test it against a set of ordered data because that is what caused the original error.

  Unfortunately, the error occurs in the scenarios the tag and script-based.

  There is absolutely no sense why this happens.  The order of a set of data should have no impact on a query of a query on a column defined as varchar.

  If there are null values in the other columns defined as a type of digital, big deal, the code in question does not seek to assess these columns.  Still more interesting thing is why disorderly orderly vs makes a difference.

• When you perform the query from the query, it assumes that the field is numeric

  I have a query that has 30 some files inside from an AS400 file. Now, when I do a query on the query, he thinks one of the columns is a numeric field, even if it is not. Now I do the same thing with another query (with the same file and fields, just different data) and it works fine.
  
  This is the error I get: the 73 "d" value cannot be converted to a number
  
  This column looks like this for example
  75
  75
  71
  71
  75
  73
  75
  63%
  etc. (the 73D is the only one in this column)
  
  Now in the query of queries I question not even this field (there are about 10 fields in the query, and I want the results of one) and then I get the above error. Any ideas?
  
  Thanks in advance,

  you create the original query? If so, create the AND define the data types:

  newQ = QueryNew ("user, lastLogin, manager", "varChar, time, bit");

  CF will build the query result based on the first line of data (if you are not
  define the data types in the original query), which resembles digital data.

  > 73D

  Thus, when it hits this row it will fail.

  If you do not use the data in that column, and then not put it back. Otherwise, use it.

  Why he behaves differently in oracle? Is there a way I can fix this problem in oracle?
  
  Thank you
  Jigs

  It is NOT a behavior "differently" in Oracle; you did not specify just an order that you expect of your results, so you'll get output in what order the fantasies of the database showing (ie. no guaranteed order). It is an artifact of the way the database chooses to collect the data and databases (or same sets of data within the same database) can and will most likely behave differently.

  Same SQL Server will not be guaranteed to always get your data in an orderly manner if you exclude the order by clause, even if you think that there always display the data in an orderly manner.

  Your solution is to add an order by clause, in the TWO databases, to force the order of the data output.

• How to write this query in the hierarchy

  Hi gurus,

  Really need your help on this query.  Thank you very much in advance.

    t1.key as root_key ,
  (SELECT
        t2.unit_id AS unit_id 
        level-1 AS level ,

        CONNECT BY prior t2.unit_id = t2.parent_unit_id
  
    )
     t1.name as parent_unit_name
  FROM

  I'll write a query of the hierarchy as above, and that EACH line (node, totally more than 10200) is checked as root node to see how many sheets are accessible for her... It must be implemented in a single query.

  I know inline query should NOT return multiple rows or multiple columns, but the inline elements are necessary and can certainly be made in a correct solution.

• How many times can I use a variable binding in a query of the VO?

  Is it possible that I can use a variable binding in a query of VO just once?

  I test a query that keeps throwing the Houston-27122 error by pressing the application module tester. I tried to limit the problem to the simplest possible case, and it seems that the error is caused by the fact that I use the same variable bind two or more times.

  When the query looks like this:

  

  I have run, enter 'x' and it returns me the result.

  When I change to:

  

  I have run, enter the value

  

  and immediately get the error

  

  The same thing in sqlplus runs without problem:

  

  My version of JDev is build JDEVADF_11.1.1.9.0_GENERIC_150314.0718.6673

  Please, advise.

  P. S. where can I find documentation queries are supported in your? In particular, I'm interested if I can use WITH the clause. There seems to be some confusion on this matter (see, for example, Oracle SQL WITH clause support - JDeveloper and ADF)

  Thank you.

  It depends on:

  Open your VO in JDev and go the the query page.

  In the lower part, there is a drop down 'link type', it is usually set to "JDBC-positional. In this case, you will need to provide the bind value for each occurrence of the variable binding separately.

  You could change that to "named" (don't remember the exact name). But beware, this will also affect all relatioships master retail to others your. I think that this is not a good idea to change the style of binding to a single VO.

  Good bye

• Can I get the total number of records that meet the conditions of a query using the Table API?

  Hello

  A < row > TableIterator is returned when I ask operations using the index of tables. If I want to get the total number of records, I count one by one using the returned TableIterator < row >.

  
  

  Can I get the total number of records directly meets the conditions of the query?

  I can get the total number of records directly the request of the meeting of the conditions of CLI using the command Global table - name tableName - count - index index-name-field fieldName - start startValue-end endValue.

  Can I get the same results using the Table API?

  I used MongoDB and NoSQL Oracle for about a year. According to the experience of the use of these dbs, I think mongoDB querying interface is powerful. In the contras, the query interface is relatively simple, which results is a lot of work that is usually a long time in the client side.

  Hello

  Counting records in a database is a tricky thing.  Any system that gives you an accurate count of the records will have a hotspot of concurrency on updates, namely the place where the counting is maintained.  Such a count is a problem of performance in addition to competitive access problem.   The problem is even more difficult in a system widely distributed such a NoSQL database.

  The CLI has overall command that counts, but does so by brutal force - iterate keys that correspond to the parameters of the operation.  This is how you must do this within the API.  There is not a lot of code, but you have to write.  You certainly want to use TableIterator TableAPI.tableKeysIterator (), because a key iteration is significantly faster than the iteration of lines.  Just one iteration and count.

  If you use TableAPI.multiGet () and a key with a touch of brightness full then, in fact, count the results as they are returned in a single piece (a list).

  Kind regards

• [ADF, JDev 12.1.3] To run a query on the fly is always necessary to define a VO? How to get the Id of the last line inserted in a VO...

  Hallo,

  Sometimes, in the code for my application, I need to run smaller queries to retrieve data from the database.

  I wonder if for these queries, it is necessary to define a View object or if I can avoid this for example creation and execution of a VO on the fly.

  In this case I would not define a VO, given that queries will be never used to display data, but only for the internal logic.

  A use case, I want to solve it next.

  I would like to create a function to be used after validation for last inserted record by a user in a TableVO.

  For example

  Select the Id of the Table where UserId =? and Type =?

  The query should be run in a managed bean...

  public String okButton_action() {}

  OperationBinding operationBinding is BindingsUtils.getBindings () .getOperationBinding ("Commit");.

  Object result = operationBinding.execute ();

  If (! operationBinding.getErrors () .isEmpty ()) {}

  Error handling

  return;

  }

  Here, I need to:

  1. run the query to get the Id of the last inserted record

  2 call the setCurrentRowWithKey on the TableVO to update the display

  and get the Id (identity/auto-increment) than the database

  assigned to the field
  

  return "return"; }

  If I can create a function that creates / runs the VO on the fly and return the value ID... It is best to create it in a class of public services or in the implementation class TableVO?

  I need to get the Id of the last line inserted since the ADF is not able to manage MS SQL Server identity fields (it seems that REFRESH AFTER INSERT cannot be used with non - Oracle DB).

  Any notice will be welocome.

  Thank you

  Federico

  The query should be run in a managed bean...

  Much better to execute the query in the template project.

  Example query: http://amit-adf-work.blogspot.com/2013/09/how-to-execute-sql-using-adf-application.html

  If I can create a function that creates / runs the VO on the fly and return the value ID... It is best to create it in a class of public services or in the implementation class TableVO?

  If you have the function that accepts the SQL as a parameter, then this should go to class util.

• Vs. runtime vs. ViewObject ViewObject SQL query in the xml file.

  Hello

  I wonder what is the difference between query SQL in the long term, creating a view object in the duration and the creation of a display with an XML object.

  I'm not trying to have the result set cached just to pick once.

  
  

  My code for a creation of a view in a run-time object:

  HashSet<Integer> allPersonIdThatUserHasAccessTo = new HashSet<Integer>();
              AppModuleImpl am = (AppModuleImpl)ADFUtils.getApplicationModuleForDataControl("AppModuleDataControl");
  
              String sqlStr = "SELECT up.person_id FROM user_person up where up.user_id = " + userId;
              ViewObjectImpl vo = (ViewObjectImpl)am.createViewObjectFromQueryStmt("AllPeopleUserHasAccessToVo", sqlStr);
              vo.executeQuery();
              RowSetIterator rsi = vo.createRowSetIterator(null);
              while (rsi.hasNext()) {
                  Row personRow = rsi.next();
                  Integer personId = ((BigDecimal)personRow.getAttribute(0)).intValue();
                  allPersonIdThatUserHasAccessTo.add(personId);
              }
  
              rsi.closeRowSetIterator();
              vo.remove();
  

  When should I use SQL query, when the view object use at time of execution and time to create the view object to an xml file?

  In general you should not write this code in a managed bean. Access code or in your case creating a VO belongs behind the façade in the module of the application.

  You can create the original Version, but the main difference is that it takes more time. Code everything that the definition of VO created in the data model of the application module would make too and it clears directly after the query only to create the same code again the next time you call the method.

  If the goal is not to keep the data, you can create the hashset class and call executeEmptyRowSet() on the VO (https://blogs.oracle.com/smuenchadf/entry/what_does_executeemptyrowset_d for details). This way you only need a VO that takes a parameter and gets you the same result in less time.

  5.04                         120                          4.2

  To change an existing column in a table, you can use the UPDATE or MERGE, instructions like this:

  UPDATE dgpercentagedatachart

  Percentage of VALUE = 100,00 * totalcecrating

  / lowestfeederrating

  ;

  Noramlly, tables is not redundant columns like this.  If percent can always be calculated from other columns, then it is probably better to calculate at run time and store it in the database, where you will have to be updated each time the columns it depends on change.  You can use a view to avoid having to encode them the calculation.

  If you really don't want a column that can be calculated in the same lines other columns, then use a virtual column (if you use Oracle 11 or higher).

  I hope that answers your question.

  If this isn't the case, please post a small example of data (CREATE TABLE and only relevant columns, INSERT statements) for all of the tables involved and also publish outcomes from these data.

  If you ask on a DML statement, such as UPDATE, the sample data will be the content of the or the tables before the DML, and the results will be the State of the or the tables changed when it's all over.

  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).

  The query you posted should not take more time with or without the HAVING clause.  The right of the comma before 'from' causes a compilation error very quickly anyway.

  If you get no result other than an error message, then this is not the code you are running.  Show the code you actually run, or a simplified version that has the same problem.

  If the problem was really in the HAVING clause, then you can try something like this:

  WITH got_total_cost AS
  (
  SELECT GroupName, Nom_liste
  , SUM ((a_cost/1000) * degradation * quantity * total_count * index) SUCH as total_cost
  FROM MyTable
  GROUP BY GroupName, Nom_liste
  )
  SELECT *.
  OF got_total_cost
  WHERE as total_cost <> 0
  ;

  but it would be very surprising he made all the difference.  I suspect that the problem is not really in the HAVING clause.

• Should I wait until the end of the execution time of the query for the execution plan?

  Hello Experts,

  I want to see the execution plan of the query below. However, it takes more than 3 hours. Should I wait all the time to see the execution plan?

  Note: EXPLAIN PLAN for does not work. (I mean that I do not see the actual line number, etc. with EXPLAIN the PLAN of market)

  You can see the output of the execution plan when I canceled the execution after 1 minute.

  My first question is: what should I do to see the execution plan for queries running out of time time?

  2nd question: when I cancel the query during execution in order to see the execution plan, will I see the specific plan of execution or erroneous values? Because the first execution plan seems inaccurate, what do you think?

  question 3: why EXPLAIN the PLAN for the clause does not work? Also, should I use EXPLAIN the PLAN of the clause to this scenerio? Can I see the result of running for long time without her queries?

  Thnaks for your help.

  It could also be that the plan is no longer in the cursor cache (check v$ sql_plan)

  Randolf,

  I don't understand. What you hear from the above statement that you mean A-lines and E will be incorrect, but the ratio between them remain the same. Therefore, you can deduct the bad things by comparing the differences.

  Thus, A-lines always give a wrong result for cancellation of queries, isn't it?

  Charlie,

  I think that Martin gave a good explanation. Here's another example that hopefully makes more obvious things:

  You say here that I canceled a query after about 5 minutes, and looking at the statistics of content (RowSource) I can already say the following:

  1. the estimation of cardinality of T1 is far - the optimizer estimated 100 lines, but it actually generated more than 57000 lines when the query was cancelled. If this definitely seems like a candidate at the origin of the problems

  2. the query has spent most of the time in search of random table T2

  So while it is true that I don't know final A-lines of this cancelled query information, I can still say a lot of this and begin to deal with the problems identified so far.
