• dynamic query for package does not work

  Dear members,
  
  I have problems with a package in the creation and analysis of a dynamic query in the WHERE clause. Here is an example of what I'm trying to do:
  
  PROCEDURE test_status_proc)
  wtd_cursor ON cur_type
  date_1 IN date
  date_2 IN DATE
  status in VARCHAR2,
  flag in VARCHAR2)
  
  IS
  
  status_sql VARCHAR2 (250): = NULL;
  flag_sql Varchar2 (100): = NULL;
  
  BEGIN
  
  
  Status of the IF = 'A' THEN
  lv_status_sql: = 'A ';
  lv_flag_sql: = 'Y ';
  END IF;
  Status of the 'I' = IF THEN
  lv_status_sql: = 'A ';
  lv_flag_sql: = 'n';
  END IF;
  
  Status of the 'R' = IF THEN
  lv_status_sql: = "R";
  lv_flag_sql: ='* ';
  END IF;
  
  Status of the IF = n THEN
  lv_status_sql: = 'n';
  lv_flag_sql: ='* ';
  END IF;
  
  IF status_code = 'IRN' THEN
  "lv_status_sql: = '('' N'','' R'');
  lv_status_sql: = lv_status_sql | ' OR (s.status = s.flag = "A" AND "N")';
  lv_usecalc_sql: ='* ';
  END IF;
  
  Status of the = IF'* ' THEN
  lv_status_sql: ='* ';
  lv_flag_sql: ='* ';
  END IF;
  
  OPEN FOR Test_cursor
  
  SELECT * from test_status s
  WHERE
  s.Daytime BETWEEN date_1 AND date_2
  S.status AND decode (lv_status_sql,'* ', s.status, lv_status_sql)
  S.flag AND decode (lv_flag_sql,'* ', s.flag, lv_flag_sql);
  
  The problem I have is especially with the condition 'IRN '. The suite WHERE the part of the clause looks like the following in the lv_status_sql, but the query returns all the values:
  
  -(', 'R') OR (s.status = 'A' AND s.flag =' only)
  
  Any help would be much appreciated.
  
  Kind regards

  Thanks for your reply and I completely understand your frustration. The problem is sometimes it is very difficult to describe all of the problem due to several reasons. Please take a look at my last post to see if that makes sense.

  If you really need SQL dynamic - true dynamic SQL which includes dealing with dynamic number of bind variables - then DBMS_SQL are an excellent interface to use.

  You can generate the dynamic SQL statement based on the question of whether the filter criteria is null (do not use) or not null (use as a predicate). For example

  if someParam10 is not null then
    // someParam10 needs to be used as a filter predicate
    dynamicSQL := dynamicSQL || ' and some_col_10 = :someParam10 ';
  end if;
  

  This statement can then be analyzed using the DBMS_SQL interface. The binding of values uses the same logic that was used to create predicates. For example

  if someParam10 is not null then
    // someParam10 is used and needs to be bound
    DBMS_SQL.Bind( myCursor, 'someParam10', someParam10 );
  end if;
  

  So, with this approach simplistic, you can easily create a dynamic SQL with variable predicates, dynamically bind these and run the slider.

  Bind variables are used in the dynamic SQL statements, as there are very few threats of SQL injection. And the basic principles observed for shareable SQL creation - the same set of parameters not null to filter, will result in the same SQL statement, which allows the cursor within the Pool shared for this SQL statement to be reused.

  So, technically, dynamic SQL is not a major problem (if used correctly). The major problem is that if really necessary to address the requirements of the business at hand.

  The problem I have with many comments here want to use dynamic SQL statements, is that it is used as one would use a file i/o interface.

  For file IO you want standard Open(), Read(), Write() and Close() calls. And you, the appellant, simply pass the name of the file and the data to write or to receive the data read.

  Similarly, these posters want to use SQL to open a table and read and write the data column - and do it by calling simply (and dynamically) by specifying the name of the table and column. Approaches to dynamic SQL based on one such concept is wrong. And shows that much of the ignorance of what a RDBMS is and how to use an RDBMS.

• Query to Excel

  I have a page that displays the results of a search query. I want to give users an option to export the results they see in Excel format by clicking on an icon.
  How can I do?
  
  I have a UDF that convert the query to Excel and takes the query as an argument. In any case I call after the page rendering?
  Any suggestion is welcome.
  
  Thank you

  What you are looking for in this case, some form of Ajax features. There is a pile of resources out there on Ajax that you find with a little research on Google.

  You could also accomplish this type of functionality using frames and 1 (or more) images invisible by setting their height 0. You can then direct action to the frame hidden - it keeps the current page visible while the hidden frame generates your excel.

  Cheers.

  I'm trying to get the value of the collection through the dynamic query but I am facing some problem please let me know that I hurt.

  Created a function like below to run the dynamic query to select statement

  create or replace FUNCTION rfunGetColumnValue (

  As I've suggested before:

  To get the name of the table the column

  and as others have:

  Type global temporary Tables vs. table

  If you give more context, more information about the bigger picture, more information about what you're trying to do and why you're going down the road you go down, you can return more useful information. But you seem reluctant to do.

  For the moment, your recent posts seem to just raise the same type of question - why are you doing this?

  The normal way to return data to a client is a refcursor.

  It is the most effective way.

  Not through collections that you seem to be put on the must-do approach.

• dynamic query problem

  Hello

  I am trying to understand the procedure and on the inside, I have a dynamic query with where clause:

  "Select."

  tables

  where 1 = 1

  and instr (decode (nvl (' | nvl(pCATEG,'') |))) (("*"), "*", pb.categ, upper (' | nvl(pCATEG,'') |), pb.categ) > 0'

  || NVL(pEMP_GROUP_CODE,'') |

  "and p.emp_group_code = g.emp_group_code';"

  For it, clause make sense (parameter pEMP_GROUP_CODE is not connected to any condition, or I missed something)?

  The procedure is works and connected to the application.

  Please notify

  Thank you

  Daniel

  Has been confused by "p.emp_group_code".

  What you see is probably a lexical parameter, for example the value passed on s pEMP_GROUP_CODE a condition itself as 'and table.column = 'constant', which can be zero, so if you have a value, it adds a condition, otherwise just empty space and the condition is spared.

• Unit test: is there a way to make the dynamic query of the value of running after the boot process?

  I wonder why the dynamic value query is executed before the boot process? Logically, it makes sense to run after them.

  For example, I test a stored procedure that is supposed to delete a record, and I'd like to create this test report should be deleted as part of the startup process before execution of the stored procedure call to delete this test record. Apparently the dynamic query of value not returns not the test report in as long as the query parameter to call the stored procedure under test, which makes me think that is executed before the startup process of design...

  Please advise...

  Thank you

• Sort on dynamic query problem!

  Hello
  
  I have a dynamic query written in pl/sql, when I check "Sort" for each field in the report attribute, error message resurrected as "ORA-01785: ORDER BY item must include the number of an expression in the SELECT list.
  If I do not check sort, it works very well. In my applications, I need all the fields sorted by user, how do I solve this problem?
  
  My query as below:
  
  declare
  Ask varchar2 (2000): = "select";
  s_class varchar2 (1000);
  cursor c1 is select * from demo_preference;
  Start
  for c1_val looping c1
  If c1_val.login is not null then
  query: query = | » ' || 'login ' | ',';
  end if;
  If c1_val.id is not null then
  query: query = | » ' || 'id ' | ',';
  end if;
  .......
  end loop;
  query: = SUBSTR (query, 1, length (query)-1);
  
  s_class: = ' (NVL (: P2_class, "%" |)) ''null%'') = ''%'' || "zero percent" OR
  EXISTS (SELECT 1 FROM apex_collections WHERE collection_name = "P2CLASSCOL" AND class = c001))';
  
  query: query = | » ' || ' from ming.reg_report_view1 where '.
  || ' ' || s_class;
  Return (Query);
  end;

  Maybe the internal column used when you clicked the sort is not indicated in the report. Try to use aliases when you build the query string, it might help apex internally to identify a column even if its order is changed to another user. After all, the order of the columns in the code is dynamic and I assume that even the number of displayed columns can vary that could sort on a column that is identified by a number not valid.

  How about somewhere, displaying the report query so that you know what is the exact query processing, it could give you the best information on the problem.

  If the problem persists, use a collection that is extracted these record using the same query string, then replace the report to view the collection and then set the sort column on. This way Summit could get confused about which columns are being sorted and it would just sort on a c001... C050 column as if it were a string (Yes problems with the number of sort columns when you do this).

• 30EA2 - UNIT TESTING - value dynamic query truncating dates time.

  So I use the installation of SQL Developer Unit Testing (very nice by the by) for a bit now and just recently upgraded to the latest beta version (3.0.02.83). Looks like a bug has been introduced by which the dynamic query of value are truncate all time of all DATE data type information.
  
  This causes sadness serious for my current test cases and for me since I have to go back to the previous beta version :)

  I noticed that, in the new 30EA2 parameter:

  AddVMOption - Doracle.jdbc.mapDateToTimestamp = false

  has been introduced by default in

  [SQLDEveloper_install_dir]/sqldeveloper/bin/sqldeveloper.conf

  Perhaps it has something to do with the behavior of incorrect date, try to remove the parameter and check again.

• Help needed dynamic query

  Hai I want dynamic query for framing

  If you do not need dynamic query to perform the update:

  See the code below:

  DECLARE
  p_cor VARCHAR2(10) := 'O';
  BEGIN
  UPDATE PI4 SET PI4.COR =p_cor WHERE PI4.DEP IN ('A01','A02','A03') OR (PI4. dep IN ('DAC','FTS','G12') AND PI4.COD_RC = '5L'));
