  What he does (or what I intend to do)
  take the datas of a whole bunch of pictures and put them in the "XX_JK_XB" table and make a log of the tables covered in xx_jk_logxb give just the source table and the status (OK).

  I just can't tell what is the problem here.
  
  clues?

  Seems to me that you are wrong assuming that the binding can be done by name and no position when you use immediate enforcement.

  Example:

  SQL> create table foo_tab( c1 varchar2(10), n1 number );
  
  Table created.
  
  SQL>

    2          for i in 1..10
    3          loop
    4                  execute immediate 'insert into foo_tab values( to_char(:1), :1 )' using i;
    5          end loop;
    6          commit;
    7  end;
    8  /

  As you can see, 1 PL/SQL block attempts to re - use bind variable: 1 new - and only link once.

  Fact does not work like that - you must link it again. Binding is done by bind - 1 position = 1 to the help of var, 2nd = 2nd bind using var, etc.. Name of the connection variable used is irrelevant and not unique.

• Tables created in a stored procedure cannot be used with dynamic SQL? The impact?

  There is a thread on the forum which explains how to create tables within a stored procedure (How to create a table in a stored procedure , however, it does create a table as such, but not how to use it (insert, select, update, etc.) the table in the stored procedure.) Looking around and in the light of the tests, it seems that you need to use dynamic SQL statements to execute ddl in a stored procedure in Oracle DB. In addition, it also seems that you cannot use dynamic SQL statements for reuse (insert, select, update, etc.) the table that was created in the stored procedure? Is this really the case?
  
  If this is the case, I am afraid that if tables cannot be 'created and used"in a stored procedure using the dynamic SQL, as is the case with most of the servers of DB dynamic SQL is not a part of the implementation plan and, therefore, is quite expensive (slow). This is the case with Oracle, and if yes what is the performance impact? (Apparently, with Informix, yield loss is about 3 - 4 times, MS SQL - 4 - 5 times and so on).
  
  In summary, tables created within a stored procedure cannot be 'used' with dynamic SQL, and if so, what is the impact of performance as such?
  
  Thank you and best regards,
  Amedeo.

  Hi, Frank.

  Thank you for your response. I understand that the dynamic SQL is required in this context.

  Unfortunately, I am yet to discover "that seeks to" using temporary tables inside stored procedures. I'm helping a migration from MySQL to Oracle DB, and this was one of the dilemmas encountered. I'll post what is the attempt, when more.

  In Oracle, we use [global temporary Tables | http://www.psoug.org/reference/OLD/gtt.html?PHPSESSID=67b3adaeaf970906c5e037b23ed380c2] aka TWG these tables need only be created once everything like a normal table, but they act differently when they are used. The data inserted in TWG will be visible at the session that inserted data, allowing you to use the table for their own temporary needs while not collide with them of all sessions. The data of the TWG will be automatically deleted (if not deleted programmatically) when a) a commit is issued or b) the session ends according to the parameter that is used during the creation of the TWG. There is no real need in Oracle to create tables dynamically in code.

  I noticed that many people say that the "Creation of the tables within a stored procedure" is not a good idea, but nobody seems necessarily explain why? Think you could elaborate a little bit? Would be appreciated.

  The main reason is that when you come to compile PL/SQL code on the database, all explicit references to tables in the code must correspond to an existing table, otherwise a djab error will occur. This is necessary so that Oracle can validate the columns that are referenced, the data types of those columns etc.. These compilation controls are an important element to ensure that the compiled code is as error free as possible (there is no accounting for the logic of programmers though ;)).

  If you start to create tables dynamically in your PL/SQL code, so any time you want to reference this table you must ensure that you write your SQL queries dynamically too. Once you start doing this, then Oracle will not be able to validate your SQL syntax, check the types of data or SQL logic. This makes your code more difficult to write and harder to debug, because inevitably it contains errors. It also means that for example if you want to write a simple query to get that one out in a variable value (which would take a single line of SQL with static tables), you end up writing a dynamic slider all for her. Very heavy and very messy. You also get the situation in which, if you create tables dynamically in the code, you are also likely to drop tables dynamically in code. If it is a fixed table name, then in an environment multi-user, you get in a mess well when different user sessions are trying to determine if the table exists already or is the last one to use so they can drop etc. What headache! If you create tables with table names, then variable Dynamics not only make you a lot end up creating (and falling) of objects on the database, which can cause an overload on the update of the data dictionary, but how can ensure you that you clean the tables, if your code has an exception any. Indeed, you'll find yourself with redundant tables lying around on your database, may contain sensitive data that should be removed.

  With the TWG, you have none of these issues.

  Also, what is the impact on the performance of the dynamic SQL statements in Oracle? I read some contrasting opinions, some indicating that it is not a lot of difference between static SQL and SQL dynamic in more recent versions of Oracle DB (Re: why dynamic sql is slower than static sql is this true?)

  When the query runs on the database, there will be no difference in performance because it is just a request for enforcement in the SQL engine. Performance problems may occur if your dynamic query is not binding variable in the query correctly (because this would cause difficult analysis of the query rather than sweet), and also the extra time, to dynamically write the query running.

  Another risk of dynamic query is SQL injection which may result in a security risk on the database.

  Good programming will have little need for the tables of dynamically created dynamically or SQL.

• Dynamic SQL with a Ref Cursor

  Hello
  
  I have a package that returns a Ref Cursor, in this procedure, I have a dynamic sql code that is built according to certain values, and the query is a select query, is it possible that I can put that dynamic sql in the ref cursor and return of the procedure.
  
  Or y at - it no alternative better workaround.
  
  Thanks in advance.

  Yes you can.

  Try this...

  create or replace package test_pack is

  procedure just_print(ref_var ref_cur);
  end;
  /
  
  create or replace package body test_pack is
  procedure just_print(ref_var ref_cur) is

• Do not pass the datetime value to store the procedure

  Hello

  I have a stored procedure that will receive the date passmeter and I write it as follows:

  < IsDefined ("form.yy") cfif >

  < cfsqltype cfprocparam = "CF_SQL_TIMESTAMP" value = "#CreateDate (form.yy, form.mm, form.dd) #" >

  < cfelse >

  < cfprocparam cfsqltype = "CF_SQL_TIMESTAMP" value = "null" null = "yes" >

  < / cfif >

  When I do not seized the day, it runs correctly.

  However, it returns me error when I entered the day:

  Conversion failed when converting datetime from character string.

  How can I solve the problem?

  Finally, I find that I can pass the parameter correctly. The problem is the dynamic sql in the stored procedure and already solved using CAST and CONVERT. Thank you.

• Quoted string inside dynamic SQL

  Hello
  My version of db: database Oracle 11 g Enterprise Edition Release 11.2.0.1.0 - 64 bit Production
  
  I run this code in a proc, and it goes to the exception block without running the code below:

  EXECUTE IMMEDIATE
      'SELECT LISTAGG (entitlement, '''','''') WITHIN GROUP (ORDER BY entitlement)
      FROM XMLTABLE (                                 
          ''''/ROWSET/ROW/ENTITLEMENTS/ENTITLEMENT''''

          COLUMNS ENTITLEMENT VARCHAR2(30) PATH ''''.'''')'                                    
      INTO v_str;

  I made a mistake with quoted strings and I have tried different combinations, but anyway his does not work.
  THA real piece of code is below, whick I'm trying to run immediately in a string

  SELECT LISTAGG (entitlement, ',') WITHIN GROUP (ORDER BY entitlement)                              
                                          FROM XMLTABLE (

    <ENTITLEMENT>JCB</ENTITLEMENT>
  </ENTITLEMENTS>
  </ROW>
  </ROWSET>'

  My goal is to get
  v_str = AMEX, JCB
  Please advice.

  Hello

  Use the notation by Q.
  Assuming that the dynamic control does not contain a right brace immediately before a single quote, you can say:

  
  sql_txt := Q'{SELECT LISTAGG (entitlement, ',') WITHIN GROUP (ORDER BY entitlement) ...}';
  dbms_output.put_line (sql_txt || ' = sql_txt');
  -- EXECUTE IMMEDIATE sql_txt;
  

  With Q-rating, you can't excape double, or otherwise single quotes.

  When you write code dynamic SQL, put the full command in a single VARCHAR2 variable (such as the sql_txt above). During the test, display it. If it looks right, then a comment the line where actually run you it.

• Dynamic SQL with dynamic identifiers

  Oracle 10gXE
  
  I have a table that is used to track student attendance. If the student is present on a given day, a record is inserted with the student ID and the date they frequented.
  
  presence of DESC
  Name of Type Null
  --------------- -------- ------
  ID NOT NULL NUMBER
  NUMBER OF STUDENT_ID
  SITE_ID NUMBER
  DATE OF ATTENDANCE_DATE
  
  I want to view a report (in TOP) which shows all students for a given site, the days when school was in session for this month (not Saturday, Sunday) and a X for the student who participated in that day or a null value if they do not have.
  
  ID # FNAME LNAME 3 4 5 6 7 10
  38754636 POE JANE X X X
  81248754 DOE KAYLA X X X X X
  43127409 RAO JOHN X X X X X
  
  In this example, days 3 and 7 of the month are from Monday to Friday and 8-9 have been excluded because they are on Saturday and Sunday.
  
  I am trying to find a way to dynamically generate a query for any month/year and returning to a report. The obstacle is that given that I don't know in advance which days in a month will be excluded, the identifiers in my select statement are not fixed.
  
  I found a query that returns a list of day numbers and dates for a given month. It looks like this:
  
  SELECT LEVEL lv, TO_DATE (TO_CHAR (LEVEL, '09')
  || TO_CHAR (EXTRACT (TO_DATE('01-SEP-11') MONTHS), '09')
  || To_char (EXTRACT (TO_DATE('01-SEP-11') YEAR), ' 9999'), 'dd.mm.yyyy') mon_day
  OF double WHERE ROWNUM < = EXTRACT (DAY OF LAST_DAY (TO_DATE('01-SEP-11')))
  CONNECT BY LEVEL = ROWNUM
  
  I combined this request with another brings my student attendance data and results that pivots in what I need. Then, I created a function that accepts the month and year as parameters and creates the combined request.
  
  SELECT c.ID student_id, c.last_name, c.first_name,.
  MAX (decode (mon_day, ' 01 - SEPT.-11', 'X', NULL)) '1', MAX (decode (mon_day, ' 02 - SEVEN.-11', 'X', NULL)) '2 ',.
  MAX (decode (mon_day, ' 05 - SEPT.-11', 'X', NULL)) '5', MAX (decode (mon_day, ' 06 - SEPT.-11', 'X', NULL)) "6."
  MAX (decode (mon_day, ' 07-SEP-11', 'X', NULL)) '7', MAX (decode (mon_day, ' 08 - SEPT.-11', 'X', NULL)) "8."
  MAX (decode (mon_day, ' 09 - SEPT.-11', 'X', NULL)) '9', MAX (decode (mon_day, 12-SEP-11', 'X', NULL)) "12."
  MAX (decode (mon_day, 13-SEP-11', 'X', NULL)) '13', MAX (decode (mon_day, 14-SEPT-11', 'X', NULL)) "14."
  MAX (decode (mon_day, 15-SEP-11', 'X', NULL)) '15', MAX (decode (mon_day, 16-SEP-11', 'X', NULL)) "16."
  MAX (decode (mon_day, 19-SEP-11', 'X', NULL)) '19', MAX (decode (mon_day, 20-7.-11', 'X', NULL)) "20."
  MAX (decode (mon_day, 21-SEP-11', 'X', NULL)) "21", MAX (decode (mon_day, 22-SEP-11', 'X', NULL)) '22 ',.
  MAX (decode (mon_day, 23-SEP-11', 'X', NULL)) '23', MAX (decode (mon_day, 26-SEP-11', 'X', NULL)) "26."
  MAX (decode (mon_day, 27-SEP-11', 'X', NULL)) '27', MAX (decode (mon_day, 28-SEP-11', 'X', NULL)) "28."
  MAX (decode (mon_day, 29-SEP-11', 'X', NULL)) '29', MAX (decode (mon_day, 30-SEP-11', 'X', NULL)) '30 '.
  (SELECT level lv, TO_DATE (TO_CHAR (LEVEL, '09')
  || TO_CHAR (EXTRACT (TO_DATE('01-SEP-11') MONTHS), '09')
  || To_char (EXTRACT (TO_DATE('01-SEP-11') YEAR), ' 9999'), 'dd.mm.yyyy') mon_day
  OF double WHERE ROWNUM < = EXTRACT (DAY OF LAST_DAY (TO_DATE('01-SEP-11')))
  CONNECTION LEVEL = ROWNUM) a, b of attendance, student c
  WHERE to_char(MON_DAY,'D') NOT IN (1.7)
  AND A.mon_day = b.attendance_date
  AND b.student_id = c.ID
  Group of c.ID, student_id, c.last_name, c.first_name
  
  Now I'm stuck on what I can pass this request in to get my result. What I've read, dynamic SQL method 4 would work if I incorporate Pro/C. I hope this isn't my only option. I have considered to try to do this in a function table in pipeline, but since the columns returned are not known in advance, I can't create a corresponding data type.
  
  I'm starting to wonder if I forgot a simpler method to achieve this.

  Ignoring the actual query and looking at the dynamic SQL part of the question.

  There are 3 ways to run a dynamic select SQL in PL/SQL code.

  immediate execution requires a fixed number of bind variables, linking him in position and translates a single implicit output cursor extraction - requiring the projection of cursor to be known at the time of coding.

  REF CURSOR are essentially the same - the only exception being that it requires an extraction explicit coding process output cursor.

  DBMS_SQL differs in all of these respects. The connection is by name and not position. The connection is dynamic. Projection of the cursor must not be known at the time of coding. It is dynamically determined at runtime and fetch offers of release of the cursor with the projection of unknown SQL - coding time.

  Apex uses DBMS_SQL internally (in fact he uses DBMS_SYS_SQL properly run dynamic and specific patterns of Oracle SQL, as if a session connected as a scheme runs the SQL code). This allows the Apex to take a dynamic SQL that you enter a region (which can contain a variable number of bind variable), run it and make the projection of the cursor as an HTML report.

  Apex supports in turn also dynamic SQL - what you (Apex developer) to provide a dynamic SQL code for a region, instead of you having to provide SQL fixed (with bind variable) for the region in question.

  As Apex creates DBMS_SQL sliders, it doesn't have your SQL as a ref cursor or cursor DBMS_SQL. All they need is the source of the SQL statement. And that's what you create dynamically.

  So in the Apex, dynamic SQL means using a function from PL/SQL to return the source for Apex SQL analyze like a slider DBMS_SQL - instead of coding the source SQL statement in a fixed statement.

  So, using the option of function for an area considered in the Apex, allows you to provide the following in the code that must run to get the SQL statement for the report Apex (Apex running this as a dynamic function that returns a string):

  --// return the dynamic SQL for the report region
  return(
    case
      when :P1_OPTION = 1 then
        'select * from emp'
  
      when :P1_OPTION = 2 then
        'select * from dept where dept_id = :P1_DEPT_ID'
    end
  );
  

  You can also write a PL/SQL function that is stored in the database and call this function so that it can determine what is the dynamic SQL source code statement. For example

  --// calling database function to return the dynamic SQL for the report region
  return(
    GetDynamicReportSQL( page => 1, option => :P1_OPTION )
  );
  

  Dynamic SQL is fully supported by Apex - but does not require that you, the developer, to create the dynamic cursor and treat the dynamic linking and dynamic recovery of this slider.

  All you have to do is to provide the source code of this dynamic SQL (including the bind variable) to the Apex and it will do the whole thing from cursor for you.
