• ADF Faces 11, add where clause to the detail view in the master/detail relationship

  Hello
  
  I have two display objects only read connected by a link in a relationship master detail.
  
  They are displayed in a treetable in the form.
  
  I have a method on the java object impl view master class, I use to add custom where claused based on entries different user and then run the query.
  
  Works well, master and detail is interview properly.
  
  But I also want to further filter the detail view (view from destination in the display link). However, as soon as I add whereclause in the detail view against the master
  relationship of detail seems to have disappeared and are no detail record. I also tried to add a view criteria but with the same result.
  
  Your comments will be appreciated.

  You can get the ViewLinkAccessor, then the ViewObject and try to apply the ViewCriteria, followed by executeQuery... what you are already doing.

• Expand the view read-only object where Clause

  Hello
  
  Is there a way I can add another where, condition of the clause to a viewobject unalterable in my bean limit support more query? The view object has a where clause itself clause which I want to thank. However, it is not editable or based on an entity object.

  Hello

  You can use ViewCriteriaRow to add where clause dynamically.

  http://download.Oracle.com/docs/CD/E15051_01/apirefs.1111/e10653/Oracle/JBO/ViewCriteriaRow.html

  In addition, you can also use a variable binding in the where clause and use setWhereClauseParams method before calling executeQuery.

• dynamic where clause ofa

  Dear all,

  I have a problem in the dynamic where clause in the OPS.

  I have a VO query as below:

  SELECT desc, ccuid, containid, XXXTMP conainline

  I'll put whereclause as below:

  VO.setwhereclause ("containid '101' =" + "order by containline desc")

  so the question is request forms as below:

  SELECT desc, ccuid, containid, XXXTMP conainline

  (where containid = '101' containline desc order) -query gives question, adding the command from the inside of the caliper

  Ideally, order by clause should come outside of the Stirrup.

  so, how do I do order by clause order side where clasue or how do I remove the stand before the where clause. So I need the query as below:

  SELECT desc, ccuid, containid, XXXTMP conainline

  (where containid = '101' containline desc order)

  SELECT desc, ccuid, containid, conainline from XXXTMP where containid = '101' containline desc order

  or

  SELECT desc, ccuid, containid, XXXTMP conainline

  (where containid = '101') order by containline desc

  Thank you

  Hello

  Solution 1-

  You can use "setOrderByClause (containline desc);" so that it will get out of Where clause.

  Solution 2-

  Instead of dynamically add Whereclause, you can bind the variable as below-

  Query in VO-

  SELECT desc, ccuid, containid, conainline from XXXTMP where containid =: 1 containline desc order

  
  

  In VOImpl-
  

  public void initQuery (String variable)

  {

  clearCache();

  setMaxFetchSize(-1);

  setWhereClause (null);

  setWhereClauseParams (null);

  setWhereClauseParam (0, variable);

  executeQuery();

  }

  Vall of this VOImpl method, and pass the variable value. It will work according to your requirement.

  Thank you

• Interactive report dynamic where clause

  Hello!
  
  Is it possible that a report interactive sql source can have a where clause clause that is built dynamically?
  
  Marc

  Marc:

  You could empty the record-ID set in a collection of the APEX.
  Change the IR query to add a join for this collection. Something like

  select c1, c2,c3...
  from  main_tab a, apex_collections b
  where b.name='RECORD_IDS'
  and a.pk_col=b.to_number(c001)

• Need help with dynamic where clause.

  Hello world.  I'm kind of a novice with PL/SQL, so please be patient with me.  I am building a web application using Weblogic Oracle 11 g and Oracle database.

  To make a long story short, I need to generate the complex dynamic WHERE clause.  I don't know what will be the name of the column or the operator of comparison or the value will be until the moment of execution.

  I'm not 100% certain, but I think I need to use dynamic SQL statements.  Unless there is a better way to do it.

  I'm sure that using dynamic SQL opens me up to SQL injection attacks if I use simple string concatenation.  I would like to use bind variable if possible.

  In any case, it seems like trying to build a dynamic where clause does not seem to work as I want it would be...

  bv1 := 'colA = 5 and colB >= 9';
  
  query_str := 'SELECT * FROM view WHERE :bv1';
  
  OPEN CUR FOR query_str USING bv1;
  

  The code above pours out when I try to run it.

  Is there a way to build dynamic where the provisions without the use of concatenation of simple string that leaves me open to attacks by SQL injection?

  Thank you

  Hello.  I have read briefly upward on things, you suggested, but it seems a bit abstract for me since I was a novice.

  Can you give us an explanation or an example of how to use it to accomplish what I need to do?

  Do ypu really plan create a query with a WHERE clause that contains a predicate for all possible columns?

  Variable bind offer performance when the same query is executed several times with different values for bind variables.

  Select * from emp where empno =: v_empno

  After the first run Oracle will always be this query in the library cache. The next running can use the version of the cache even if the bind value is different.

  Select * from emp where empno =: v_empno;

  Select * from emp where ename =: v_ename;

  Select * from emp where sal =: v_sal;

  Each one is a DIFFERENT query. Yes - each of them uses a variable binding, but queries are different.

  So, if your username select EMPNO, an '=', and a value from the first query can be executed. But the next time that the user can select the ENAME column so that 'stored' first request may not be used given that the query does not match.

  The third time your user selects SAL so none of the first two queries can be used in the library cache. The use of bind variables gives performance during the SAME QUERY is used multiple times with DIFFERENT values for the variable binding. Oracle is not to analyze the hard query everything simply because the VALUE is different.

  So bind variables do not help you if most of the queries were completely DIFFERENT sets of predicates. And SYS_CONTEXT will not help either since that simply provides a way to define binds the values of the variables.

  Just for the simple example above, there are at least SIX possible combinations of columns that could choose your user name: empno, ename, sal, empno ename, empno & sal, ename & sal

  Here he works for the purchase order number but the where cluase does not work for Supplier Site. Please help as soon as possible.
  
  
  2 and also if supplier site to return multiple values then this field should show as messagechoice. If it returns a single value, then it should be the style text message
  How can I achieve this.
  
  
  
  Thank you
  CSK

  Try

  vo.setWhereClause ("IN vendor_id (" + vendor_id_qry + ")" ");

  vendor_id_qry is the query that retrieves the list of provider IDS. You don't need to put the vendor column id as whereClauseParam unless you want to have IN the clause in your query of VO and pass the list as 1,2,3 values to the parameter.

  Thank you

• Dynamic where clause of user defined reports

  Hello everyone,
  
  Is there a way to make / calculate a where clause clause in a user defined report according to the value of some bind variables?
  I am trying to remove where the terms of my application if the binding variable is not defined.
  previously, I did something as
  AND tab.column = nvl (: colum_bin, tab.column)
  
  but there are problems in implementation plans.

  Sure that you can not, but how about you to rewrite the NVL in

  where: P1_DEPT_LOC IS NULL or dept_loc =: P1_DEPT_LOC

  If dept_loc is not null better would be

• Try adding conditions to clause "and" stored in the table for the where clause, unknown syntax

  I am trying to add additional segments to the 'where' clause, and I don't know exactly how to proceed. I am currently using another table to search for keywords and sometimes there aren't everything. I use this table containing the key words to search the description and associate a symbol with a path.

  The code loops through the keywords with the keywords most associated and try to find links to a symbol then excludes those and search for symbols that correspond to those with less keywords and all. I am able to do this with 6 queries and manually changing the arguments, but I want to loop together so that if the changes need to be made in the future, I won't need to go digging in the code.

  Thanks, but that's ok. I already have a solution for this.
