  Do you want user input in the command of the COIL, or want you she in the query?

  the colsep value,-separate the columns with a comma

  What are the data type gen_date of the oif?
  If it is a string, it is a big mistake. Information about the dates in the DATE columns belongs.
  If it's a DATE, so don't try to compare strings, such as "2012-11-01 00:00:00:00000'."

  spool off;

  The reason is to give the opportunity to the user so that he can enter any beach without changing the code of the script.

  Can someone help me please.

  One way to do that is with substitution variables:

  ...
  SET     VERIFY  OFF
  
  ACCEPT  start_gen_date     PROMPT "Starting date (e.g., 2013-02-18 23:00:00.00000): "
  ACCEPT  end_gen_date     PROMPT "Ending date   (e.g., 2013-02-18 23:59:59.99999): "
  
  SPOOL  spool_results.csv
  
  SELECT    *
  FROM        gui_site_journal
  WHERE        gen_date  BETWEEN '&start_gen_date'
                  AND     '&end_gen_date'
  ORDER BY  gen_date;
  
  SPOOL  OFF
  

  There are security considerations. Variables substitution to the devious users the power to issue a SQL, such as DROP TABLE command. Users with SQL * Plus access already have this power, anyway.

• 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.

• Ensure this soft analysis the use of Bind variables

  Hi Experts,
  
  I have a request when the query is prepared dynamically in Java code and if I take the query and run it from SQL Navigator, it takes a long time to prepare the statement and then execute it quickly. I think we can use dynamic SQL statements and bind variable to improve performance here. However, I tried to do a PDS to check my understanding. I created 2 procedures
  
  1. mode of operation

  CREATE OR REPLACE PROCEDURE sp_static
  (id IN NUMBER, 
   name in VARCHAR2)
  IS 
  TYPE r_curs_type is REF CURSOR;
  C1 r_curs_type;
  BEGIN
  
  OPEN C1
  FOR
  SELECT * FROM TABLE WHERE columname = id
  
  CLOSE C1;
  
  END;

  2. mode of operation

  CREATE PROCEDURE sp_dyanmic
  (id IN NUMBER, 
   name in VARCHAR2)
  IS 
  TYPE r_curs_type is REF CURSOR;
  C1 r_curs_type;
  BEGIN
  
  OPEN C1 FOR 'SELECT * FROM TABLE WHERE columnanme = :U1' 
  USING ID;
  
  CLOSE C1;
  END;

  To my amazement, there is no difference in the duration of execution of these procedures when I ran the with multiple entries.
  
  Please note-
  1. I have not access to trace files :-(
  2. I want to just make sure there will be improved performance before starting the real work, given that some efforts provided by moving the logic of all its activities inside and the use of bind variables.
  
  If you can suggest a strategy to ensure performance gains, it will be extremely useful...
  
  Thanks in advance!
  Concerning

  Hello

  (1) it's true, procedure 1 also uses a variable binding
  (2) you seem to be confused about the very basic concepts here

  Dynamic SQL is something like this:

  create or replace FUNCTION f (l_table_name VARCHAR2) RETURN NUMBER
  IS
    l_result NUMBER;
  BEGIN
    EXECUTE IMMEDIATE 'SELECT COUNT(*) FROM ' || l_table_name  INTO l_result;
    return l_result;
  END;
  

  In this example, since you do not know the name of the table to the execution table, everything you can
  is dynamic SQL. As you can see, neither of your two procedures is like that.

  Dynamic SQL is used when you do not know what columns you want to select, or who
  etc. to the execution table. You can also use dynamic SQL statements to force analysis. You can not use
  to avoid parsing, binding or not binding.

• Functions defined by the user with several parameters

  I set features three following user using "Define."

  UF1 takes a single patameter;

  UF2 takes two parameters;

  and UFX takes two parameters - with the second is 'X' in the definition.

  

  Œuvres F1.  F2 is the EVAL of F1 version and it works too.  User functions only seem to work fine.

  F3, a function of two user settings, produces a graph of NaN.

  F4 is the EVAL of F3 version.  Note that 'B 'is not replaced by 1'.  Also produces a NaN chart.

  F5 produces a graph of NaN.

  F6 is EVAL of F5.  The 'X' is not replaced (even with the ' B' above), and even if it looks like 'X * X', it also produces a graph of NaN.

  

  Is it possible to get defined by the user, with several parameters, features work by tracing the curve?

  Hi!, Fortin:

  If you download and install the ultimate Firmware with the version of the software: 2015 6 17 (8151), with the number of Version: 1.1.2 - 11, you can trace your examples of definition of the function, with curves and values, without NaN.

  I have a big script with multiple INSERT and DELETE statements. I have been asked by DBA to use bind variables rather than direct assignment parameter values in which the condition.

  Impossible.

  Use of variable bind from a client means:
  (1) customer create a unique SQL cursor with bind variable, for example INSERT INTO FOOTABLE VALUES (: 1,: 2: 3)
  (2) customer from a loop of data read
  2.1) reading the customer data (from file, network, device, whatever)
  customer liaison variables 2.2) cursor (assigning values to 1 to 3 SQL cursor variables)
  2.3) client running the cursor
  line insertions 2.4) database
  loop repetitions of 2.5) client for all data
  (3) customer closed the SQL cursor

  This can be done using a SQL script - as a SQL script is not a loop where a single insertion cursor is used. It's a unique script with 100 or 1000 of SQL insert statements. Where each insert statement will result in a cursor SQL must be created.

  SQL * also does not support the approach of customer liaison above variable. It is a command line interface very PRIMITIVE and unsuitable for running scripts from loading/data entry.

  In your case - the right approach would be to have the data into a CSV file, and then load this file using SQL * Loader... where this software will use customer approach above (in fact he still does better because it uses in bulk link and link not row as described above).

• 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 (: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.

  Hello
  The best practice would be to create the file in My Documents for the user currently logged in windows.

  Unfortunately, you did not mention your version of forms. In an older version like 6.x it is function in the library of d2kwutil called Read_Registry in the win_api_environment section, and in the more recent versions the same availble function in the library webutil to client_ name.

  So, you can read the registry database for the current logged in user using the function mentioned above of the location next to the register.
  My Computer\HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell folders

  There is an entry named personal. Read the path of this entry when running while generating / record file to the customer's location and save the file in this path.

  David

  Hi David,

  The reason why I proposed to do this is to display date CREATED_ON as you want in the report. If you do not do this, the date can be displayed in a format that you don't like. You don't have to do this bit, if you do not want.

  For example, if you do not set the size, the date may appear as:

  6 NOVEMBER 08

  But, if you set the format, you can get:

  2008-06-11 12:13:15

  It is up to you.

• Relationship between the objects in view with bind variable executed by program

  Hello

  I am trying to create a view link between two objects in view that are query based something like this:

  firstVO

  1. Select P1 in XXX_Table where P2 =: BindVariable1 and

  P3 =: BindVariable2;

  secondVO

  2. Select B1, B2, B3, B4, 1 m env in YYY_Table where B5 =: BindVariable1 and

  B6 =: BindVariable2 and

  B7 =: BindVariable3;

  concatenation of a string of the query above in AMImpl as 'and B8 in ('P1.a', 'P1.b', 'P3.c')' in the AMImpl

  I will execute queries above, based on the variable bind entered by the user in the AMImpl.

  I need to create a link to firstVO.P1 and secondVO.P1 with a 1-based view to * cardinality.

  the problem is when I try to drop the secondVO which is an accessor to the firstVO as a master-child relationship with master table form and as a child, I don't see the details of the child when I iterate the master shape.

  I got my problem solved, the problem was that the master and the children were not in the sink, we can define the child VO by substituting preparerowsetforquery... explained clearly in the post below.

  Binary: Defining the value of variable binding for the destination View object in the link display

• JDev 11.1.2.1 method Execute (with bind variable) before the page is displayed

  Hi all
  
  I have a view object with a query that uses a variable binding. I drag the data on my .jsf page control to create a table. I create a query method on a bean in sight. The query method uses the content of one of the attributes of the bean to set the link for the query variable:
  
  vo.setNamedWhereClauseParam ("CraIdBindVar", sessionBean.getCraId ());
  
  I put a button on the page that calls the method of the request and it fills the table. That's fine, but I don't want the user to have to click the "query" button when browsing this page. I found forums dealing with create an AMImpl.jave method, create a link on the page, create an executable file for the link. It works that the method is executed until the page appears. However, the AMImpl method cannot call sessionBean.getCraid () to obtain the data required to complete the binding variable.
  
  Is it possible to run my method of view range bean before the page is displayed? Or maybe a way for the AMImpl.java method to access the range of view variable?
  
  Thank you, Steve

  Steve,
  You can drag a call method on the workflow activity. Select the new method call activity, and open the property inspector. Here you choose your bean method in the method property. Now, first of all, you go to this activity of method call, then the page.

• The use of bind variables (in & out) with sql dynamic

  I have a table that contains code snippets to make postings on a set of pl/sql database. what the code does is basically receives an ID and returns a number of errors found.
  To run the code, I use dynamic sql with two bind variables.
  
  When codes consists of a simpel query, it works like a charm, for example with this code:
  

  BEGIN
     SELECT COUNT (1)
     INTO :1
     FROM articles atl
     WHERE ATL.CSE_ID = :2 AND cgp_id IS NULL;
  END;

  However when I get to post more complexes that must perform calculations or run several queries I run into trouble.
  I have boiled down the problem into that:
  

  DECLARE
     counter   NUMBER;
     my_id     NUMBER := 61;
  BEGIN
     EXECUTE IMMEDIATE ('
        declare 
           some_var number;
        begin
        
        select 1 into some_var from dual
        where :2 = 61; 
        
        :1 := :2;
        end;
  ')
        USING OUT counter, IN my_id;
  
     DBMS_OUTPUT.put_line (counter || '-' || my_id);
  END;

  This code is not really make sense, but it's just to show you what is the problem. When I run this code, I get the error
  ORA-6537 ON bind variable linked to a position IN
  
  The error doesn't seem wise,: 2 is the only one IN bind variable and it is only used in a where clause clause.
  As soon as I remove this where clause, the code works again (giving me 61-61, in case you want to know).
  
  Any idea what goes wrong? I just use bind variables in a way that you're not supposed to use it?
  
  I'm using Oracle Database 11 g Enterprise Edition Release 11.2.0.3.0 - 64 bit

  Correction. With immediate execution , the binding is in position, but binds do not need to be repeated. My statement above is incorrect...

  You must link only once - but bind by position. And the connection must correspond to the use of the variable binding.

  If the connection never variable assigns a value in the code, link by in.

  If the binding variable assigns a value in the code, link as OUTPUT.

  If the binding variable assigns a value and is used a variable in another statement in the code, link as IN OUT.

  For example

  SQL> create or replace procedure FooProc is
    2          cnt     number;
    3          id      number := 61;
