• Report using Bind Variables

  Hey everybody,
  
  I have a little trouble to create a report. I need the FROM part of the code in order to use bind variables. I came up with this piece of code below, but im getting the following error:

  AHA, but when you have changed the source, have you also changed the Type (from "SQL query" to "SQL Query-PL/SQL function return SQL Query")?
  And clicked on "use generic names (analysis of query runtime only) column" option below the source code?

• Estimate of poor cardinality using Bind Variables

  Hi I'm using the 11.2.0.4.0 Oracle version. I have a query that is underway for the plan of the poor execution by the estimate of poor cardinality for two tables (I've extracted and published this part only) as I mentioned below, the individual conditions for which the estimate goes bad and moving entire query execution path.

  These are for two tables and currently we use BIND variable for them in our code, and I notice, its best estimate gives with literals. I need to know how to handle this scenario that I need this query to execute for all types of volumes. Is there something I can do without changing the code, as it works well for most of the execution? In the current scenario of the main query that uses those below tables providing a plan (index + nested loop) that works very well for small volume, but running for 10 hr + for large volume as ideally its going to the same regime.
  And Yes, most time that this request will be hit for small volume, but killing some appearance of large volume presents the performance of the queries.

  
  Here are the values of the variable binding.

  B1 VARIABLE VARCHAR2 (32);

  B4 VARIABLE VARCHAR2 (32);

  In fact for literals, I did not find any section of the predicate after running the sql code with activation "set autotrace traceonly explain."

  The main problem is with another large query whose cardinality is underestimated due to the presence of these table (table1, table2) with the above mentioned clause, and the query is for the analysis of index + nested with values of Bind loops and take 10 hr +, whereas with literals, its completion in ~ 8minutes with FTS + Hash Join.

  Your real problem is that you try to have just a single SQL query handle all POSSIBLE thanks to the use of embedded FILTERS ' either / or ' filters in the WHERE clause.  You want only a select this OPTION to run whatever filters have been selected at run time by the user or the application using it.  And it would never work.  You really need to SELECT different queries for different combinations of filter conditions.

  Why?  Think for a minute.  How Oracle works internally?  A SQL SELECT query gets analyzed and an execution plan is produced which is stored in the library cache and gets REUSED on all subsequent executions of this query - except in certain cases where there may exist several plans run through several cursors of the child.  So with only SELECT a query you only AN execution plan in the library cache, to be used by all THE executions of this query, regardless of the value of your run-time binding variables.

  Lets put another way - each library cache execution plan is associated with a SQL statement.  If you want a DIFFERENT execution plan then you need run a DIFFERENT SQL statement.  That's how you get a different execution plan - by running a different SQL statement.  Running the SAME SQL query generally you will get the SAME execution plan every time.

  In addition, because of the "either / or" filters that you use you will end up generally with a full Table Scan on each of the referenced tables.  Why?  Given that the optimizer must produce an implementation plan that manages all possible contingencies for all values of possible bind variables in the SELECT.  If the optimizer should choose to use any index based on one of these "either / or" filters then it would only help performance when real value was provided, but it would be really bad if a NULL value was supplied.  If the optimizer ends up ignoring the index because they are not always optimal for all possible input values and instead chose a plan that is "good enough" for all input values possible.  That means that it will use a scanning Table full.

  I hope you can see that it is precisely what is happening for you with your query.  You select this OPTION to manage the different combinations of filter, which leads to the execution plan only one, which leads to scans full Table on the referenced tables in these ' either / or ' filters.

  The solution?  Build queries SELECT DIFFERENT when input values are NULL.  How you do that?  Read this article to ask Tom that tells you:

  http://www.Oracle.com/technetwork/issue-archive/2009/09-Jul/o49asktom-090487.html

  To sum up - when you have real value for a bind variable 'bind_var1' add the following filter to your CHOICE:

  AND column_name1 =: bind_var1

  When the binding variable is NULL, add the filter according to your CHOICE:

  AND (1 = 1 OR: bind_var1 IS NULL)

  Now, you'll have 2 queries SELECT must be performed, which have exactly the same number of variables in the same order bind, which is important.  When you then run one of these variations, Oracle can analyze and optimize each one SEPARATELY, with a single execution by the SELECT query plan.

  When you provide a real value, the filter is a normal 'column = value' that the optimizer can use all indexes on this column, because NULL values are not referenced.

  When there is no real value, the optimizer will analyze the '1 = 1 GOLD' and realize that "1 = 1" is set to TRUE and GOLD, it is quite TRUE regardless because the binding variable is null or not.  This means that the optimizer will actually REMOVE this filter, because it filters nothing because it is always TRUE.  You will end up with an operating plan based on the other filters in the query, which is what you want because you have no filter on this column.

  What is it - producing distinct SELECT queries to determine if you have a real value to filter or not you end up with DIFFERENT execution plans for each of them, and each of them is OPTIMAL for this particular set of filters.  Now you get good performance for each variation of the performance of the SELECTION, rather than sometimes good and sometimes very bad when using SELECT only one.  It is impossible to try to get multiple shots of execution 'optimal' out of a SELECT query.  That's why you get mediocre performance under different bound the values of the variables.

• problem with bind variables in the SQL query view object

  Hi all

  I use JDev 11.1.2.4.0.

  I have a problem with bind variables in the SQL query view object.

  This is my original SQL

  SELECT sum(t.TIME) , t.legertype_id
  FROM LEDGER t
  WHERE t.nctuser_id = '20022' 
        AND to_char(t.insertdate,'YYYYMMDD') in ('20130930','20130929')
  group by t.legertype_id
  

  In my view .xml object query tab, I am writing this

  SELECT sum(t.TIME) , t.legertype_id
  FROM LEDGER t
  WHERE   t.nctuser_id = '20022'
      AND to_char(t.insertdate,'YYYYMMDD') in :dddd
  group by t.legertype_id
  

  Davis here is a variable of Type liaison: String, updatable and necessary.

  I try to deal with Davis as ('20130930 ', ' 20130929') hoping the view object, run as my original SQL.

  But failed. The view object retrieves 0 line after that I run.

  Why?

  Thank you! ('2original SQL0130930', '20130929') ('20130930 ', ' 20130929')

  A variable binding cannot be used as this is why you must use years table. Check decompilation binary ADF: using oracle.jbo.domain.Array with ViewCriteria to see a solution.

• Problems with Bind Variables

  SELECT co.ref_num, co.forename, co.surname, co.dob, a.address, a.postcode,
         co.ni_num
    FROM address a, contact co
   WHERE co.ref_num = a.ref_num
     AND (:1 IS NULL OR co.forename = :2)
     AND (:3 IS NULL OR co.surname = :4)
     AND (:5 IS NULL OR a.postcode = :6)
     AND (:7 IS NULL OR a.address = :8)
     AND (:9 IS NULL OR co.dob = :10)
     AND (:11 IS NULL OR co.ni_num = :12)

  With a jdbc connection, we use a web front end for a new management system. The SQL above runs since a search screen. We meet a few serious problems with bind variable and execution plans. When the above query is sent by the database 'AND' clauses could evaluate as follows:
  

  AND ('Tim' IS NULL OR co.forename = 'Tim')
     AND ('Clarke' IS NULL OR co.surname = 'Clarke')
     AND ('' IS NULL OR a.postcode = '')
     AND ('' IS NULL OR a.address = '')
     AND ('25051981' IS NULL OR co.dob = '25051981')
     AND ('' IS NULL OR co.ni_num = '')

  We cannot dynamically assign 'AND' conditions so they are sent through to the database. This translates FTS 99% of the time as the execution plan never prescribed any of the available indices.
  
  Someone has suggestions on how to better 'control' bind variables?

  Hello

  Don't you think that 'OR' Conditions are necessary to check for Null, where the binding variable is NULL or not.

  I think that rather than running the query from the front to FB, try to convey the values of some MS and run this query in the procedure, the extraction from the point of view Design coding application. Never fire the query of the frontal part.

  To come to the problem.

  SELECT co.ref_num, co.forename, co.surname, co.dob, a.address, a.postcode,
  Co.ni_num
  ADDRESS, contact co
  WHERE co.ref_num = a.ref_num
  AND (: 1 co.forename IS NULL or =: 2)
  AND (: 3 co.surname IS NULL or =: 4)
  AND (: 5 a.postcode IS NULL or =: 6)
  AND (: 7 a.address IS NULL or =: 8)
  AND (: 9 co.dob IS NULL or =: 10)
  AND (: 11 co.ni_num IS NULL or =: 12)

  Use the procedure.

  Fact exits of the indexes on the tables and stats are updated...?
  Try to predict explain it. ??

• Correct way to use Bind variables when you use an interface to MS SQL Server

  Hey,.
  I have some difficulty to find how to use bind variables in a view, when you use an interface to MS SQL Server. For some reason when I use an ApplicationModule who has a library of MS SQL Server JDBC loaded and I try to click on OK when you change the following query:
  
  SELECT kit_status, component_id
  OF numbered_inv
  WHERE trialname =: 1
  
  I get an error stating that ' SQL Query Error Message incorrect syntax near ':'. JDeveloper is compatible with SQL server for bind variable as this query works fine if I replace the: 1 with a Word to say "Test test".

  You have made a typo. bind variables are preceded by two points, while you put a colon in front of the equality operator that he listens to it in the PL/SQL assignment operator. Change:

  WHERE io.orderlocation : = 1

  TO

  IO.orderlocation WHERE =:1

  Change:

  WHERE ITEMLOCATION : = 2

  TO:

  WHERE ITEMLOCATION =:2

  Change

  AND itemname : = 3

  TO:

  AND itemname =:3

• Using Bind Variable in a SELECT statement

  Hello
  
  I am trying to build my SQL query running using bind variables and in Oracle® Fusion Middleware Fusion developer Guide for Oracle Application Development Framework 11 g Release 1 (11.1.1) it is said that ' after you define bind variables, the next step is to reference them in the SQL statement. While SQL syntax allows you to bind variables to appear in the SELECT list and in the WHERE clause, you'll generally use them in this context, as part of your WHERE clause. ».
  
  However, when I try to use bind variables in my SELECT list because I had set a type to the string of the variable variable is inserted with quotes each side for example SELECT TestTable FROM 'Service '. Is it possible to use bind variables to insert a value in my list of selection without the quotes around it?
  
  Thanks in advance,
  Tom

  Hi Robinst,

  I think you want to set up column name of the table that is not possible using bind variables. With the help of the bind variables you can send a value to the SQL. The String value is therefore always with inverted commas.

  Kind regards

• printing problem in pdf and csv using bind variables

  Hello

  How are set the bind variable? If there are topics evaluated by default on the elements of the page, so is not necessarily enough to ensure that the exports are their values. To set values, I tend to use calculations, conditional that the element is null, what works "Before Header". In this way, the value is stored in the session and is available for export. I think the defaults to be those that are defined when the page is submitted and are not available until now.

• DATACOPY function problem using several variables quick

  Hello

  I have problem when I use more variables and then a quick calculation with DATACOPY function. When I put a prompt variable in function DATACOPY it works but when I add one or more it gives me error Essbasse (I can see it in the Essbase Administration journal not in the syntax checking process):

  Not valid [Calc Script syntax

  -Essbase put FY14 because it is rapidly Variable in this error above.

  I try datacopy function with this:

  DATACOPY Q1020-> Dec-> "FY14 '... It works

  DATACOPY Q1200-> Dec-> {YearPrompt}... It works

  DATACOPY Q1200-> Dec-> {YearPrompt}-> {ScenarioPrompt} it doesn't it break on variable ScenarioPrompt.

  Thank you

  Finally, I solved my problem. That was the problem Essbasse how to understand the spaces between the dimensions. I didn't not use quotes for members and I put space between the arrows. It gave me an error I think because he did not understand space as the space. Now, when I use quotes and remove the space between the arrows cross dimensions it works.

• Problem with Bind variable cannot be changed.

  Hi all
  I use Jdev 11.1.2.3.0. In my VO, I created a Bind Variable and set it NOT UPDATABLE. Then, I created a display with some other Variables Bind criterion.
  I use this criterion to display on a search page, but when running, I see also an inpunt for the defined variable NOT UPDATABLE text and I can't change its value.
  Of course, if I try to change the value, and I do research, I get an error.

• How to get SQL that do not use bind variables

  Hello
  
  I am trying to identify the SQL code which should benefit from the use of bind variables.
  First of all, I tried to get the common signature of all the sql calls, using:
  

  select * from (
  select  force_matching_signature, count(1) from v$sql where force_matching_signature<>0 group by force_matching_signature order by 2 desc
  ) where rownum < 50;

  Then I copied these values to the Clipboard and run:

  select sql_text from v$sql where force_matching_signature=<<<copied_signature_value>>>;

  Now, I want to make it automatically and get only 1 occurrence of each SQL that resembles others by using a query.
  
  I tried this:
  

  select sql_text from
  (
  select sql_text, force_matching_signature, row_number() over (partition by force_matching_signature order by sql_text desc)rn from v$sql where force_matching_signature <>0
  )where rn <2 and rownum < 10 order by force_matching_signature desc

  But it is not returning results by showing up at the count (1) from the first query, I've used. How can I change this if I get the results in order of "importance"?
  
  
  
  
  Thank you

  And I said. First use the command by then use rownum. I did not mention row_number. Also, there should be no need to add more columns.
  Have you tried it? Why it did not work?

  example not tested

  select * from (
     select sql_text from (select sql_text, force_matching_signature, row_number() over (partition by force_matching_signature order by sql_text desc) rn from v$sql where force_matching_signature != 0)
     where rn = 1
     order by force_matching_signature desc /* add any ordering you like here */
     )
  where rownum < 10  /* then filter on the first 10 results */
  

  If you want to order that the statement that found most of the time comes first, say so. However, I don't see how to group in your case.
  Maybe like this

  example of tested

  select * from (
     select cnt, sql_text
     from (select sql_text, force_matching_signature, row_number() over (partition by force_matching_signature order by sql_text desc) rn , count(*) over (partition by force_matching_signature) cnt
           from v$sql
           where force_matching_signature != 0)
     where rn = 1
     order by cnt desc, force_matching_signature desc /* add any ordering you like here */
     )
  where rownum < 10  /* then filter on the first 10 results */
  ;

• Can OBIEE use Bind Variables?

  I doubt that it would be used for warehouse queries, but I'm the question arises. Has anyone used in OBIEE?
  
  [Here is a brief summary about them. | http://www.akadia.com/services/ora_bind_variables.html]

  I checked with the support of Oracle and it's official - OBIEE does not support the bind variable.

• Bind variables in SPARQL WLS jena queries

  Hi all

  We read about the possibilities of support of jena to bind the variables in the documentation (http://docs.oracle.com/cd/E11882_01/appdev.112/e25609/sem_jena.htm#RDFRM248). The problem has been addressed in the next section on 14 June 2014 (Bind Variables in SPARQL queries). However, we are facing other problems.

  We use:

  * WLS 12.1.3.0.0

  * adapter jena 2.11.1.

  * Joseki 3.4.4.

  * ARQ 2.9.2.

  We try to run the following query on the stop of joseki.

  PREFIX foaf: http://xmlns.com/FOAF/0.1/ >

  PREFIX vcard: http://www.w3.org/2001/vCard-RDF/3.0# >

  PREFIX ORACLE_SEM_FS_NS: http://Oracle.com/Semtech#no_fall_back, ODS = 6, ALLOW_DUP = T, s2s >

  PREFIX ORACLE_SEM_HT_NS: http://Oracle.com/Semtech#monitor >

  PREFIX ORACLE_SEM_UEAP_NS: http://Oracle.com/Semtech#f$ RDFVID % 20 to (?) >

  PREFIX ORACLE_SEM_UEPJ_NS: http://Oracle.com/Semtech#f $RDFVID >

  PREFIX ORACLE_SEM_UEBV_NS: http://Oracle.com/Semtech#1264839720472151591 >

  SELECT? f? g

  WHERE

  {graph? g {? vcard:N p? vn.}}

  ? VN vcard:Family? f.

  ? FOAF:title p 'Sen'.}

  }

  However, the result that we get back does not use the variable binding. It returns the entire list without UEAP/UEPJ/UEBV.

  Is there something that I missed in the documentation or should I define some variables for the use of bind variables?

  Kind regards

  Max

  Hi Max,.

  Can you please define the following JVM property to the WLS and restart the middle range?

  -Doracle.spatial.rdf.client.jena.allowAP = true

  This configuration is only necessary when running a variable binding based SPARQL query from a web service endpoint.

  Let me know if this can help,

• Problem with the selection list dynamic LOV using bind variables

  I have the following SQL to fill a selection list:
  
  Select d, ch from
  (
  Select ft. FAMT_NAME d, pi. R FAM_ID_T of FAMILY_TRA ft
  Join the ck list
  on ck.family = ft.famt_name and ck.newseq in (: NEWSEQ_QUERY_SQL)
  )
  
  Where NEWSEQ_QUERY_SQL is a part of the application that is defined by a calculation of page and essentially returns a list of values NEWSEQ based on some parameters of the user query. For example:
  
  Select distinct (ck.newseq) in the ck list where rownum < 20
  
  The query above works fine with SQL Developer and returns two columns needed (display_value, return_value)
  
  However, it returns no line, when it is used to fill the LOV to a selection list.
  
  If I replace the: NEWSEQ_QUERY_SQL with a list of NEWSEQ hard-coded, it works:
  
  Select d, ch from to)
  Select ft. FAMT_NAME d, pi. FAM_ID_T r
  of FAMILY_TRA ft join checklist ck on (ck.family = ft.famt_name and ck.newseq in ('K0242900', 'K0217200'))
  ) ;
  
  I can even replace: NEWSEQ_QUERY_SQL with hard-coded SQL and it works:
  
  Select d, ch from
  (
  Select ft. FAMT_NAME d, pi. R FAM_ID_T of FAMILY_TRA ft
  Join the ck list
  on (ck.family = ft.famt_name and ck.newseq in (select ck.newseq from the list ck where rownum < 20))
  )
  
  But if there is a connection variable (: NEWSEQ_QUERY_SQL), it doesn't.
  
  Selection lists are driving me crazy! They seem incredibly capricious.

  Hello:

  You cannot link a "sql statement" that bind the value you're trying to do.
  P2_FAMILY_LIST must be the SQL statement you executed for the LOV. Something like

  select d, r from
  (
  select ft.FAMT_NAME d, ft.FAM_ID_T r from FAMILY_TRA ft
  join checklist ck
  on (ck.family = ft.famt_name and ck.newseq in (select ck.newseq from checklist ck where rownum < 20))
  )
