I need help with dynamic input text

• 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

• Newb needs help with dynamic text

  Hello world
  
  I'm not a newb - but that's how...
  
  I am trying to create a multi-page form that allows uses to register the products.
  The first page asks you name etc., and on the second page, I want to say "Welcome"+ username "!" -This kind of thing...
  The problem is that I can't seem to keep the values of dynamic text through the pages.
  
  I can get it to repeat the entry on the first page with this code:
  
  _root.firstname_txt. OnChanged = function() {}
  _root.firstname_repeat. Text = "Hello"+ _root.firstname_txt.text; "
  };
  
  However when I call on the second page it is not defined:
  
  second_repeat. Text = "Hello"+ _root.firstnamt_txt.text; "
  trace (_root.second_repeat.text);
  
  I'm sure it's something simple and I am just a dunce of programming...
  Any help is appreciated.
  
  your

  If your textfield (_root.firstname_repeat) does not exist on the 2nd frame, its text property will be indefinite.

  to remedy, or extend the existence of your textfield in frameworks or use a variable to store its text property (in your manager onChanged) and use this variable to retrieve the value you need.

  import flash.utils.Timer;

  I should start at 0.  The code works fine then you might need to see if you need to incorporate your policy in the textfield to get it to display.

  Everything by getting rid of aid ';', but the output of the select statement is not displayed?

  When you use a SELECT statement in PL/SQL, you must select the results in variables or arrays.
  Try something like this:

  DECLARE
       CURSOR C1 IS
                     SELECT  TABLE_NAME
              FROM    DB_MGMT.CTRL_TAB_RETENTION

              AND     rownum                  < 2;
  
       min_dt_skey    NUMBER;
       max_dt_skey    NUMBER;
       stmt            VARCHAR2 (100);
  BEGIN
      FOR i IN C1
       LOOP
  
          -- dbms_output.put_line('Table Name: ' || i.TABLE_NAME);
  
          stmt :='SELECT min(DT_SKEY), max(DT_SKEY) FROM DWH_RSRC_PERF.' || i.TABLE_NAME;
  
          dbms_output.put_line(stmt);
  
          EXECUTE IMMEDIATE stmt
           INTO min_dt_skey, max_dt_skey;
       dbms_output.put_line (  min_dt_skey   || ' = MIN (dt_skey), '
                      || max_dt_skey   || ' = MAX (dt_skey) for table '
