SQL Bind Variables workshop - Date issues

• Bind variables and dates

  I am writing a process to delete records based on dates.

  Here is the chart:

  Column name	Data type	Nullable	Default	Primary key
  ID	NUMBER	NO.	-	1
  CT_NAME	VARCHAR2 (100)	Yes	-	-
  CT_CATEGORY	VARCHAR2 (100)	Yes	-	-
  BASE_PTS	NUMBER	Yes	-	-
  PROD_PTS	NUMBER	Yes	-	-
  REF_PTS	NUMBER	Yes	-	-
  START_DATE	DATE	Yes	-	-
  END_DATE	DATE	Yes	-	-
  CREATED_ON	DATE	Yes	-	-
  CREATED_BY	VARCHAR2 (50)	Yes	-	-
  UPDATED_ON	DATE	Yes	-	-
  UPDATED_BY	VARCHAR2 (50)	Yes	-	-

  start_date and end_date are the fields of date key.

  The query will remove the dates with specific start and end dates.  The question I have, is that I get a ORA-01858: a non-digit character was found here where was waiting for a digital error while the query is running.

  remove from ct_point_values

  where start_date =: P4_START_DATE_V

  and end_date =: P4_END_DATE_V

  If I run the query in the sql window, no problem:

  remove from ct_point_values

  where start_date =' 01 / 01/2014 '

  and end_date = 31 December 2014"

  Find the query with the works of values hard-coded.  Links to fail.  I tried casting and to_char to_date variations with no luck.

  One thing that I notice, is that when I go to enter my bind variables in the sql workshop, the fields are pre-populated with this:

  1 & amp; #x2F 1 & amp; #x2F; 2014

  12 & amp; #x2F 31 & amp; #x2F; 2014

  01/01/2014 and 31/12/2014.  I found that the only element relates to this suggests that this is a possible bug:

  SQL Bind Variables workshop - Date issues

  Any thoughts on how to address this issue, or is it really a bug?

  I run on Apex 4.2, 11g.

  Thank you!

  Hello

  I guess that these dates come from elements on the page to which the user can select a range of dates.

  These fields have a custom format mask?

  What seems to be the case for me, is that these fields have an explicit format mask (for example: DD/MM/YYYY) but the default database/session format mask is something different (e.g. DD-MON-YYYY).

  I suppose also that the issue in the SQL workshop isn't something related.

• Update MS SQL for APEX pl/sql - Bind variable/field process table

  I created a page APEX that updates a table of linked server sql through the call to a pl/sql process 'submit '.
  The anonymous pl/sql block refers to a hidden field on the page titled "P3_RECORD_ID" in the place where it is clause.
  The pl/sql block, I invoke is:
  
  Start
  commit;
  Update "SRSRATINGS".
  'Status' value = 'PASS '.
  where "Record_ID" =: P3_RECORD_ID;
  commit;
  end;
  
  This is block if I replace it with a literal numeric value for the variable/hidden bind field: P3_RECORD_ID. However, when I use the link variable: P3_RECORD_ID, I get the following error:
  
  ORA-02070: SRS database. MSSQL does not support the TO_NUMBER in this context
  
  He doesn't seem to understand that P3_RECORD_ID is a reference to the primary key on the form field.
  
  Any help is appreciated.

  Hello:

  Try if edit the pl/sql block below work

  declare
  l_num number := :P3_RECORD_ID;
  begin
  commit;
  update "SRSRATINGS"
  set "Status" = 'PASS'
  where "Record_ID" = l_num ;
  commit;

• SQL * more substitution vs bind variable question

  Hi all, I am trying to automate some SQL within SQL codes * more script that is triggered by a script .bat, the only parts that change are Dates...

  example:

  create table blah as

  Select * from table

  WHERE DATE between start_date and END_DAY;

  the DATE is a numeric field, YYYYMMDD

  The script runs always at the beginning of a new week, so a Monday, unless a public holiday, then a Tuesday.

  The END_DAY is * always * last Friday and I realized that:

  variable L_FRIDAY char (15);

  Start

  Select to_char (next_day(sysdate-7,'FRIDAY'), 'YYYYMMDD') as Last_Friday in: double L_FRIDAY;

  end;

  /

  The thing is that I get an error when I try to use the binding variable?

  create table blah as

  Select * from table

  WHERE DATE between start_date and: L_FRIDAY;

  Then once I found the end date, I was going to use add_months(L_FRIDAY,-12) for previous 12 months for the start_date...

  When I tried to use a variable Substitution I could just hard code the date, but I can not or do not know how to set the value of this exec to the variable?

  Help!

  :-)

  Basically my research reveals that - Bind variables are not allowed for operations of data definition, use substutions instead of bind variables

  I need an automated way to find the END_DAY which is last Friday and START_DATE that is 12 months before Friday and refer to those in the SQL without errors.

  Or SQL * more bind variable or variable substitution can be DATEs.  The best you can do is set a different type, as a string, representing a date.  A string as June 19, 2015"represents a date, but so strings like 'SYSDATE' and ' SYSDATE - 7', so you can do something like this:

  SET l_friday = ' NEXT_DAY ((SYSDATE-7), 'FRIDAY').

  DEFINE start_date = "ADD_MONTHS (& l_friday, - 12)"

  SELECT & start_date AS t_n

  , & l_friday AS l_f

  OF the double

  ;

  Output (when executed on 25 June 2015):

  L_F T_N

• How to pass a list as a bind variable in SQL Developer?

  How can I pass a list as a bind variable in SQL Developer?
  
  The following query in SQL Developer so work I put ": prmRegionID = 2.
  
  SELECT COUNTRY_ID,
  COUNTRY_NAME
  OF HUMAN RESOURCES. COUNTRY
  WHERE IN REGION_ID (: prmRegionID);
  
  The problem is that I can't find how to set ": prmRegionID = 2, 3.
  
  I know that I can replace ": prmRegionID" by a proxy '& prmRegionID '. The above query will work well with"& prmRegionID = 2" and with "& prmRegionID = 2, 3". "
  
  But with this solution, I lost all the benefit of the use of bound variables (analysis hard against soft parse, possibility of SQL injection, etc.).
  
  I'm learning how to do this in SQL, as well as the use of UDT in this thread: How to move a list as a bind variable?
  
  But with this solution, I've lost nice SQL Developer user interface. In SQL developer, it is easy to test a query using the standard binding variable. When we start the application, a pop up asking for a value of the variable binding.
  
  With the UDT, the interface request always variable binding standard. You have an idea on how I can get a variable string binding (such as 1, 2, 10) in a set of NUMBER or VARCHAR2? This way I would be able to launch a standard query in SQL Developer to test my application.
  
  
  Can someone tell me what is the best approach to this?
  
  Thank you in advance,

  Hi Blais,

  Thank you for trying the SQL and PL/SQL instance before coming here - it was definitely the right approach, and you've got some very good suggestions there. Your needs for a invite only bind to the value in the clause list, I think I have a possible solution. I'll introduce you to a list of characters, so you'll have to tweak it for other types of data. First, add the following to your schema:

  create or replace
  TYPE bind_tab_typ AS TABLE OF VARCHAR2(4000);
  
  create or replace
  FUNCTION comma_to_table(iv_raw IN VARCHAR2)
  RETURN bind_tab_typ
  PIPELINED
  IS
     ltab_lname dbms_utility.lname_array;
     ln_len     BINARY_INTEGER;
  BEGIN
     dbms_utility.comma_to_table(list   => iv_raw
                                ,tablen => ln_len
                                ,tab    => ltab_lname);
     FOR i IN 1 .. ln_len LOOP
        PIPE ROW (ltab_lname(i));
     END LOOP;
  END;
  

  Now you can write a query, say for scott.dept, as follows, and have executed statement ask the value list in the clause as a single binding variable:

  select *
  from dept
  where dname in (
    select * from table( comma_to_table( :BNDS ))
  );
  

  When you are prompted, provide the list of values separated by a single comma without any extra spaces.

  I don't know if the Varchar2 (4000) really needs to be which is great. I use it because that's what dbms_utility.lname_array uses.

  Kind regards

• bind variables in pl/sql static

  Hello world.
  This feature will be works faster than the function below without binding? (I mean if he calls very often, and execution plan is in cache)

  FUNCTION get_amployee_name (empid INTEGER, empcity VARCHAR2) RETURN VARCHAR2 IS
      TYPE GenericCursor IS REF CURSOR;
      c1 GenericCursor;
      empname VARCHAR2(200);
  BEGIN
      OPEN c1 FOR SELECT ename FROM employees WHERE id = :id AND city = :city USING empid, empcity;
          FETCH c1 INTO empname;
      CLOSE c1;
      RETURN empname;
  END;

  FUNCTION get_amployee_name (empid INTEGER, empcity VARCHAR2) RETURN VARCHAR2 IS
      empname VARCHAR2(200);
  BEGIN
      SELECT ename into empname  FROM employees WHERE id = empid  AND city = empcity;
      RETURN empname;
  END;

  I tried to find info related to the execution of pl/sql query steps, but cannot. Optimizer does use the values of real variables in pl/sql to generate the exec. plan? Or it will be generated only once when the function performed the first time?

  Reference and discusses this in Chapter 1 PL/SQL user's Guide

  http://download.Oracle.com/docs/CD/B19306_01/AppDev.102/b14261/overview.htm#sthref145

  "When you embed an INSERT, UPDATE, DELETE or SELECT SQL statement directly in your PL/SQL code, PL/SQL transforms the variables in the WHERE clauses of the VALUES to automatically bind variables. Oracle can re-use these SQL statement every time the same code is executed. To execute statements similar with different values of variables, you can save the analysis of overhead by calling a stored procedure that accepts parameters, and then issues the declarations with the parameters substituted in the appropriate places. »

• Convert SQL to take advantage of the Bind Variables

  Is it possible to convert the SQL below so I can enjoy variable Bind?  It's just my personal way of followed by the name of the script that I use on a daily basis... the file is passed to a point that its about 2K lines long, and whenever I run this specific file to get a script name, it creates a new SQL in the database pool shared... I tried to change this option to use bind variables , but it doesn't seem to work properly and I wanted what suggestion of the community...

• 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.

• Can I use session variables in data model BI publisher SQL query?

  Hi Experts,
  
  We apply security at the level of the BI Publisher 11g data.

• How to get SQL that do not use bind variables

  Hello
  
  I am trying to identify the SQL code which should benefit from the use of bind variables.
  First of all, I tried to get the common signature of all the sql calls, using:
  

  select * from (
  select  force_matching_signature, count(1) from v$sql where force_matching_signature<>0 group by force_matching_signature order by 2 desc
  ) where rownum < 50;

  Then I copied these values to the Clipboard and run:

  select sql_text from v$sql where force_matching_signature=<<<copied_signature_value>>>;

  Now, I want to make it automatically and get only 1 occurrence of each SQL that resembles others by using a query.
  
  I tried this:
  

  select sql_text from
  (
  select sql_text, force_matching_signature, row_number() over (partition by force_matching_signature order by sql_text desc)rn from v$sql where force_matching_signature <>0
  )where rn <2 and rownum < 10 order by force_matching_signature desc

  But it is not returning results by showing up at the count (1) from the first query, I've used. How can I change this if I get the results in order of "importance"?
  
  
  
  
  Thank you

  And I said. First use the command by then use rownum. I did not mention row_number. Also, there should be no need to add more columns.
  Have you tried it? Why it did not work?

  example not tested

  select * from (
     select sql_text from (select sql_text, force_matching_signature, row_number() over (partition by force_matching_signature order by sql_text desc) rn from v$sql where force_matching_signature != 0)
     where rn = 1
     order by force_matching_signature desc /* add any ordering you like here */
     )
  where rownum < 10  /* then filter on the first 10 results */
  

  If you want to order that the statement that found most of the time comes first, say so. However, I don't see how to group in your case.
  Maybe like this

  example of tested

  select * from (
     select cnt, sql_text
     from (select sql_text, force_matching_signature, row_number() over (partition by force_matching_signature order by sql_text desc) rn , count(*) over (partition by force_matching_signature) cnt
           from v$sql
           where force_matching_signature != 0)
     where rn = 1
     order by cnt desc, force_matching_signature desc /* add any ordering you like here */
     )
  where rownum < 10  /* then filter on the first 10 results */
  ;

• The use of bind variables (in &amp; 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;
    4  begin

    6  'declare
    7          n       number;

• Get the bind variables name string SQL or the cursor

  Hello
  
  Is there way to get of the bind variables name string SQL or the cursor?
  
  Example of

  DECLARE
    l_sql VARCHAR2(2000);
    desctab DBMS_SQL.DESC_TAB;
    curid   PLS_INTEGER;
  BEGIN
  
    l_sql := 'SELECT * FROM emp WHERE mgr = :X and deptno = :Y';
  
    curid := dbms_sql.open_cursor;
    dbms_sql.parse(curid, l_sql, dbms_sql.NATIVE);
    ....
  END;

  What I mean with the SQL string:
  I love to get using some functions from above code variable l_sql all the bind variable.
  In this case the function should return array where is for example: X and: Y
  
  Back to bind the cursor variable names, I mean same but rather string I pass number of cursor.
  
  Y at - it sucks ready function or some may share a code customized for this purpose?
  
  Thanks
  
  Kind regards
  Jari

  I found there are wwv_flow_utilities.get_binds of the function not documented in APEX packages that do what I want.
  Usage example

  set serveroutput on
  DECLARE
    binds DBMS_SQL.varchar2_table;
  BEGIN
    binds := wwv_flow_utilities.get_binds('select :P1_TEST from dual');
    FOR i IN 1 .. binds.count
    LOOP
      dbms_output.put_line(binds(i));
    END LOOP;
  END;
  /
  
  anonymous block completed
  :P1_TEST

  But I would not use these functions without papers as those who can change or there is no future versions APEX.
  Is there a documented function or the custom function that do the same thing as wwv_flow_utilities.get_binds?

  Some old basic example code of my friends. Also the media getting the bind variable of PL/SQL code blocks anon.

  PS. just realize this code is case-sensitive, while variable bind is not. Should throw a upper() or lower() by adding the name of the var to the list - never really a problem for me because I'm pretty tense when it use cases correctly in the code. ;-)

• Correct way to use Bind variables when you use an interface to MS SQL Server

  Hey,.
  I have some difficulty to find how to use bind variables in a view, when you use an interface to MS SQL Server. For some reason when I use an ApplicationModule who has a library of MS SQL Server JDBC loaded and I try to click on OK when you change the following query:
  
  SELECT kit_status, component_id
  OF numbered_inv
  WHERE trialname =: 1
  
  I get an error stating that ' SQL Query Error Message incorrect syntax near ':'. JDeveloper is compatible with SQL server for bind variable as this query works fine if I replace the: 1 with a Word to say "Test test".
  
  Thanks in advance

  Use positional JDBC Style Binding to bind variables
  Try to use? Instead of:
  As shown here:
  http://www.Oracle.com/technetwork/developer-tools/jdev/multidatabaseapp-085183.html

• Query report back "No data found" with bind variables

  I put a simple query in the report query:
  
  Select "bluefish". 'name' as 'name',
  "bluefish". "" primary_flag "as"primary_flag. "
  "bluefish". "" status "than"status. "
  "bluefish". ' ' ID ' as 'ID' of "bluefish" "bluefish" where "bluefish". "" ID "=: P3_XPRINTID
  
  When I test the query, the data is returned. However, when I try to run the query using the "Test report" button, I get an error 01403 no data found. If I replace the link with an explicit value variable, the report runs.
  
  Anyone have any ideas as to what is causing this problem? I use the generic report layout, with different types of output. I'M editting the query and set the binding variable before test report (otherwise, the query is not executed).

  In fact the report would go - unlike other products of Oracle who complain about a missing binding variable, Apex is not complaining but interprets as a null value. So if you hurt typed the name of your variable, you are never alerted to it.

  Check the Session window to make sure that it is a value - the most common questions are that you named the wrong variable in the query or your item has no value in session state again.
