• bind the parameter, Q1

  Hello everyone,
  We do great for user input parameters. We used the report wizard and changed the data by adding: where table.date BETWEEN: Enter_Start AND: Enter_End
  
  We received the message, "Note: the query"Q - 1 "has created the parameters bind"Date_Start","Date_End"."
  We didn't pay attention couples suite:
  1. ' Q - 1'
  2 bind the parameter (s)
  
  We just clicked OK, then, then buttons only. We were happy labels: Enter Start and End.
  
  Nothing is simple!
  We have some challenges when it comes to change: Enter_Start AND: Enter_End to: First_Date AND: Second_Date.
  
  where table.date BETWEEN: First_Date AND: Second_Date
  
  Now we have 4 labels: begin to enter, enter end, Date of the first and second Date. We want only 2 labels and 2 input parameters.
  
  If you have experience on the topic, please share with us.
  
  Thanks in advance,

  Yes. Note that the ID parameter for valid column transmitted by the user name.

  I suppose that space must be in 'ORDER BY ' | : ID. What I mean like that...

  :order_by_clause := 'ORDER BY '|| :ID
  

• The USE of dynamic SQL clause

  Hi all
  I'm moving a table as a variable in dynamic SQl but with no result. Suppose that I it running on HR diagram example:

  declare
  sql_state varchar(100);
  hire_date date;
  temp_table varchar(9):='employees';
  
  begin
  sql_state:= 'select hire_date from :1 where employee_id=206';
  
  execute immediate sql_state into hire_date using temp_table;
  dbms_output.put_line('hire_date is '||hire_date);
  end; 
  
  declare
  *
  ERROR at line 1:
  ORA-00903: invalid table name
  ORA-06512: at line 9

  I get this error of invalid table name without knowing what was read for the variable. Any advice?

  Hi Valerie,

  To add to what Peter, said

  "Binding" values in a query is done for a specific purpose, and this purpose is so that the optimizer can use the same query as the previous execution plan runs the query, which prevent it from having to analyze the hard the query each time. A query execution plan is based on the tables and columns are presented in the query, but with respect to the actual "values" of these columns, they are unlikely to change the execution plan. So, to keep the same execution plan, the query must seem identical (in terms of a query string) like the previous series, so if you want the same query, but just with different values, they can be replaced with bind variables (these things have a ': ' character) and then the values passed in the query, when it is run.

  Now, if Oracle were to allow you to link in the names of objects, such as tables, this means that it could not use the previous execution plans, because he doesn't know until run time what tables will be consulted. Therefore, it would be useless link in the values of the query and it would be just as quick to implement your query string by concatenating all the values inside rather than link them. Considering that a query is parsed first and then the values in it, then it cannot be analyzed if the tables are not known everything first. (Take a look at how queries are formed and variables when you use the DBMS_SQL package).

  So the key thing to remember is that, when it comes to bind variables, you can bind only the 'values', not 'objects '.

• pass the parameter in pl/sql block

  Hello
  
  I have to call anonymous pl/block block with the shell script parameter. It works fine as indicated below, the problem is - generated email after the creation of the table in step contains

  Detaching Frank, however, and echoing my previous comment, let them down and to re-create the tables makes no sense. It is logical to truncate a table if you test a load. If you build a data warehouse, it makes sense to delete and re-create a partition if you rerun a load for a particular date and that you have daily partitions. Deletion and recreation of a table in a stored procedure is not a reasonable way to test a system (nor is there a reasonable way to approach change control issues that will inevitably produce when you need to change the structure of a table).

• Dynamic SQL in APEX

  Hey everyone, I'm trying to understand how to use dynamic sql statements in Application Express. Specifically, I'm trying to write a query using substitution/bind variables. I don't know if you need a description of the application or not, but here's the query that will run in sqlplus:
  

  ACCEPT     file_id     PROMPT     "Enter the file_id (a number, e.g. 3): "
   
  -- Preliminary Query, to set table_name
   
  COLUMN     reference_id_col     NEW_VALUE     reference_id
  COLUMN     table_name_col     NEW_VALUE     table_name
   
  SELECT  f.reference_id          AS reference_id_col
  ,           t.reference_table       AS table_name_col
  FROM      aa_files     f
  JOIN     aa_type     t     ON     f.file_type     = t.type_id
  WHERE     f.file_id     = &file_id
  ;
   
  --     Main Query
   
  SELECT  * 
  FROM     &table_name
  WHERE      reference_id     = &reference_id
  ;

  There are three substitution variables, reference_id & file_id and & table_name. My basic setup is that I have a table full of table names, so I ask her to get a table name in a variable, then query this table for my data.
  
  I work inside the window of SQL commands to try to find the proper syntax to make this work in the APEX. I'm pretty sure that APEX does not allow the use of substitution variables, because they are one thing on the side of client SQL more right?
  
  I'm still a student, so I'm not known and Oracle Application Express, but reading the documentation of the APEX and the Googling, I tell myself that bind variable should be able to do this for me, but I don't know how. I searched for some examples or documentation on the use of dynamic SQL statements in the APEX, but I could not find anything. I'm sure I could do this using a PL/SQL block, but I'd rather do it in pure SQL if possible.
  
  So if someone could help me or giving me an example of syntax I would have to use to write a query that is running in Application Express, or could direct me to the literature on the use of dynamic sql statements in Application Express, it would be greatly appreciated!
  
  If you need more information on my application, I can post my create table statements and some inserts sample data, if that would be helpful.
  
  Thank you!

  OK, so one of the great things about SQL is your ability to choose what columns you want to include in your result set. You don't have to use all of them. You can do this in two ways: with dynamic SQL or individual areas for each type of file. This will depend on your use as to how many types different files will be added each day on which you want to go with.

  If you go with dynamic SQL (and because you don't know until run time what columns you want to use, it is an appropriate use), you will need to build your query based on the file type. Something like this:

  declare
    qry_type  VARCHAR2(10);
    sql_qry    VARCHAR2(4000);
    qry_select  VARCHAR2(500);
    qry_from   VARCHAR2(100);
    qry_where  VARCHAR2(400);
    qry_order   VARCHAR2(100);
  begin
    qry_type  :=  :PX_QRY_TYPE;
    --Build the SELECT clause
    qry_select   := 'select a.FILE_NAME, a.FILE_NAME, a.FILE_TYPE, a.LOCATION';
    CASE qry_type
       WHEN 'PDF' THEN qry_select   := qry_select || ', pdf.DATE_MODIFIED, pdf.SUMMARY, pdf.AUTHOR';
       WHEN 'XLS' THEN qry_select   := qry_select || ', xls.DATE_MODIFIED, xls.SUMMARY, xls.TOTAL_VALUE';
       ...
    END CASE;
    --Build the FROM clause
    qry_from    := ' from AA_FILE a, AA_FILETYPE_PDF pdf, AA_FILETYPE_XLS xls, AA_FILETYPE_PHOTO p';
    --Build the WHERE clause
    qry_where  := ' where a.FILE_ID = pdf.FILE_ID (+)';
    qry_where  := qry_where || ' and a.FILE_ID = xls.FILE_ID (+)';
    qry_where  := qry_where || ' and a.FILE_ID = p.FILE_ID (+)';
    --Build the ORDER BY clause
    qry_order  := '';
    --Put it all together
    sql_qry   := qry_select || qry_from || qry_where || qry_order;
    EXECUTE IMMEDIATE sql_qry;
    ...
  end;
  

  Now this does not cover the addition of new file types. I still think you're going to be better off planning for as much as you can and handle manually creating additional tables, but this is going to be to you. I know you are trying to generate code to do everything for you, but when it comes to databases, I found that the creation of objects can quickly become uncontrolled if you're not very careful. These are going to be permanent, not temporary memory built database objects. Just a word of warning.

  If you decide to go with a region and by file type, it does not require nearly as much work. Simply create a report region based on the view and set the conditional display based on your file type.

    select * from V_FILES_PHOTO
     where FILE_ID = :PX_FILE_ID;
  
  condition:  FILE_TYPE = 'PDF'
  

  While you will need to add a region again every time that you add a new file type, once again, the question that arises is: file types how are you really going to have to worry? If you're talking about a dozen, I would like to do things manually. If you're talking about a hundred, it's maybe worth trying to find a method of programming. It is your call to make.

• Dynamic SQL code generation

  I'm having a problem with the generation of dynamic SQL code.

  Specifically when I use single quotes in my SQL statements, they end by showing as quotes when the query is run.

  Any ideas on how I can remdey it?

  When I view my dynamic SQL code, it looks and works fine if I run it

  AND (External_Group_Members LIKE ' % 1% ' OR External_Group_Members LIKE ' %, 3, %'))

  but when these data are transmitted to the SQL, it looks at and I get an error

  SELECT * FROM External_Groups WHERE 1 = 1 AND (External_Group_Members LIKE '% 1% ' OR External_Group_Members LIKE "%, 3, %'') ORDER BY External_Group_Name)

  PreserveSingleQuotes().

• 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;
    4  begin
    5          execute immediate
    6  'declare

• 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.

• Change the parameter [] strings in a sub - bound dynamically VI

  I'm in a situation where I need to use the sub-panels to dynamically bind subVIs for data entry. I also like having the calling VI to change the [] parameter strings several enumerations in the Subvi, but this doesn't seem to be possible, as the Subvi is not in edit mode. Does anyone know of a way around this?

  I read data from a file to initialize the enums, so that I can have the Sub - VI read the file instead, but I was hoping to do it once in the main VI and send strings to the subVIs to speed up execution.

  Thank you!

  It's impossible.  Enums are set in stone at run time.  Oh wait, you try to use the script running.  Sorry, it does not work.  Note that the property for the [Strings] node for the enum is blue?  That tells you it is a script node and is useful for mounting screws over time edit.

  As RavensFan said, you use a ring.  Their data type is a real number.

• How the date can be filled with timestamp in dynamic sql

  EXECUTE IMMEDIATE v_stmt;

  After you run the above SQL last date of update in MTH_EQUIPMENST_EXT_B is filled with sysdate but timestamp is not its always 00:00:00. Can we have timestamp also populated through dynamic sql in the last update date

  Kind regards
