• Dynamics, where the form of Clause - Oracle 10g

  Hi all

  The scenario is we provide an interface (via form 10g) to execute different queries. These requests have set the columns and tables (for example, we have same SELECT and FROM clauses for each request). However, WHERE clause is unique for each request. So, I'm writing a dynamic cursor, but DYNAMIC CURSORS are not clear for me. I post my code for taking advice from experts in the forum.

  Just so that I understand what you're trying, you are not display the results in your form, you simply run a dynamic query that you export the results to a file.  Is this correct?

  So, what happens when you run your code?  Are you an error (If Yes, what is the full error)?

  One suggestion that I have after reviewing your code example is that you don't have a space after your FROM clause before you concatenate your WHERE Clause in your sql string variable.

  Your example Code:

  ...
  FROM
  inproving_result_remarks,MTR_RET_CRD'||:WHERE_CLAUSE;
  

  There should be a space after MTR_RET_CRD.  For example:

  ...
  FROM
  inproving_result_remarks,MTR_RET_CRD '||:WHERE_CLAUSE;
  

  Without the space your SQL will not scan properly.

  Another suggestion that I have is that you move your code from collection to a stored procedure (procedure or function) in your database of data and your stored procedure returns a collection.  This will eliminate the constant travel to the database for each line of the recording because your stored procedure will return the record complete game.  In addition, your stored procedure allows you to use dynamic SQL Native (Execute Immediate) will allow instead of using dynamic SQL from forms (EXEC_SQL) package. Native dynamic SQL is much more efficient and a lot less code.  In order to use native dynamic SQL, you must have on the Oracle Database 9i or higher.

  Without a doubt.

  There are only two lines in your table and then just a Select will do the job. (I'm kidding ;-))

  If you have a hierarchical data in your tables, it might be possible:

• Where the conditional, or PL/SQL block as a source for an interactive report?

  I have this situation: my app's main screen displays a list of documents. For now, there must be a quick way to 'security' integrated, so that administrators can see all documents, but only other users can see what documents, they created (connection of the creator is stored in the table of documents). In the future we will use probably VPD to enforce certain rules, but for the moment we need a quick solution.
  
  So I stored administrators in a separate table. Now I want the interactive Act report on the homepage as follows:
  -If an admin is connected, it must have this query: select field 1, 2, 3 area in documents
  -For all other users: select the field 1, 2, area 3 documents where creator =: app_user
  
  Is this possible in a single interactive report? I could do two reports with different queries, and make conditional depending on who is connected, but this gives me two interactive reports to maintain. Is it possible to use a PL/SQL block as a source for the report? I tried, but I get a syntax error. Is it possible to do where proviso on somehow?

• Query on calculated field where deletes conditions of the clause

  Hi gurus,
  
  Under a new requirement, we have created a new field calculated in Contact before JC, which removes the condition from which to extract the clause and made full table.
  
  Requirement:
  
  We have a field in the user interface, that has data like "J1234" or "K44335". Customer won't see the first character of the alphabet of these data.
  
  Solution, we have developed:
  
  (1) create a new calculated field 'ABC person UId Calc' as follows.
  
  Name: ABC person UId Calc
  Calculated: true
  Computed value: right ([nobody UId], Len([Person UId]) - 1).
  
  (2) exposed this field in the user interface.
  
  Question:
  
  When the user queries in the applet for this field, the generated SQL code has no condition in a Where Clause to the query on PERSON_UID.
  
  SQL has earlier been something like...
  
  (T25. EMP_FLG = 'N') AND (T25. PERSON_UID LIKE: 3)
  
  But after you make this change, the current SQL is trimmed of the just
  
  (T25. EMP_FLG = 'N')
  
  This means that this isn't question with PERSON_UID, resulting in an impact huge performance.
  
  If someone could suggest on this issue, to the difficulty.
  
  Concerning

  Oh sorry, I guess I missed something.

  I guess the simplest solution is to store the values of redundantly (A, B the value of the value and the value of A + B) and stop using a calculated field.

  You could script something in the PreQuery event, but I think it's an ugly hack.

• Problem with the case where the clause

  Hello

  I want to use cases in which clause. I wrote a very simple query to test how it works. However, I always got an error message. Here's what I did.

  Select eid, firstname, lastname from employee where eid = 1 works fine

  Select eid, name, name of the employee

  where

  cases where 1 = 1 then eid = 1

  When 1! = 1 then eid = 2

  end

  I ORA-00905: lack of keyword.

  Did I miss something?

  Thank you

  Hi, Jennifer.

  Why do you want to use BOX in a WHERE clause?  The wonderful thing about the CASE is that it allows you to do IF-THEN-ELSE logic.  In a SELECT clause, or an ORDER BY clause, this is really useful, but the WHERE clause already allows you to use the IF-THEN-ELSE logic.

  However, if you use the BOX in a WHERE clause, it is as it does nowhere else.  Always BARGAIN instead of a single expression in a SQL data types.  All the clauses THEN (and ELSE, if there is one) must return a single expression, such as the NUMBER.  (There is no BOOLEAN data type in SQL).  So, you can use a CASE statement like this:

  ...

  CASES WHERE

  WHEN 1 = 1 THEN 1

  WHEN 1! = 1 THEN 2

  END = eid

  Here, the CASE expression takes the place of a NUMBER.

  However, if I was not sure if 1 = 1 or not, I would write the condition in this way, without a CASE expression:

  WHERE (1 = 1 AND eid = 1)

  OR (1! = 1 AND eid = 2).

• A clumsy behavior of the place where the clause on joins

  I have a problem to join tables querying. If i:
  
  (1) join two tables
  (2) then filter a few lines with 'where '.
  (3) then filter the result with another 'where '.
  
  It seems oracle swaps two filtering. It seems wrong for two 'where' clauses cannot be expected.
  
  How to reproduce:
  

  create table table_a(
    n_a Number);
    
  create table table_b(
    n_b Number);
    
  insert into table_a (n_a) values(1);
  insert into table_a (n_a) values(2);
  insert into table_b (n_b) values(1);
  commit;
  
  create or replace function func(p_n in Number)
    return Number
  as begin
    if p_n = 1 then
      raise_application_error(-20100, 'Redwood City, we have a problem');
    end if;
    
    return p_n;
  end;
  /

  The fact that the following query works:
  

  select *
    from table_a
    left join table_b
      on table_a.n_a = table_b.n_b
   where n_b is null;

  and it didn't 'has value 1 ='. But
  

  with t as (
    select *
      from table_a
      left join table_b
        on table_a.n_a = table_b.n_b
     where n_b is null)
  select * from t
   where func(n_a) = 2

  fails, although "func" throws the exception only on the value "1", which I assume to be absent in 't', I have filtered it earlier. The question is exposed both in oracle 10 and 11.
  
  Is this a bug or expected behaviour? In any case, how could avoid dealing with 'where' oracle as commutative?
  
  UPD
  Even easier way to reproduce without a user-defined function:

  with t as (
    select *
      from table_a
      left join table_b
        on table_a.n_a = table_b.n_b
     where n_b is null)
  select * from t
   where 1/(n_a-1) = 2

  It will trigger the divide by zero exception.

  Hello

  The optimizer may choose to evaluate the conditions in an order; He can choose to evaluate the conditions of the main query WHERE clause before it evaluates the conditions in the WHERE clause of the query-sub.
  You can force it to evaluate the subquery all first by adding ROWNUM to its result set:

  with t as (
    select table_a.*, table_b.*, ROWNUM AS r_num     -- *****  CHANGED  *****
      from table_a
      left join table_b
        on table_a.n_a = table_b.n_b
     where n_b is null)
  select * from t
   where func(n_a) = 2

  If I need to write the condition in triggering elemt itsel... How to proceed?

  for example, I want to write the condition as cost of Tota > = 100000, it must follow a path and if fails to another path.

  The conditions of triggers are specified in the workflow settings.  After you have created a new configuration, open it and click on the settings tab.  You will see a tree structure of the workflow with conditional branches.  Click a conditional branch to set the parameters for the trigger for this route condition.
