  You wrote trigger on the table of the student. So in the trigger, only the columns of this table must be offered for example: NEW.zip.

  Since zip_id is not part of this table, the: NEW.zip_id must always generate the error.

  insert into student_v (zip) values('111');

  In the above statement, you can only provide the value for the column zip but not zip_id. Therefore, the: NEW.zip_id is not available in the trigger. Must extract this value in the sequence after it is created.

  for example

  create the test of the order;

  INSERT INTO postal code

  (zip,

  zip_ID,

  created_by,

  CREATED_DATE,

  Modified_By,

  MODIFIED_DATE)

  VALUES (: NEW.zip,)

  You do not specify bind variables by a colon ': ' prefix in PL/SQL.

  The stored procedure generates a query using the string concatenation. If you remove your name from the variable of the colon you still don't use bind variables.

  If you want to use bind variables you should consider the following:

  1. use the DBMS_SQL package.
  2. use EXECUTE IMMEDIATE with the USING clause.
  3. use OPEN TO with the USING clause.

  Each has different advantages/disadvantages.

  If looks as if you want to pass in a dynamic list. If you are using bind variables, it will effectively address the entire list as a value surrounded by single quotes. If you really want a dynamic IN the list, you need to investigate another method.

  Tom Kyte contains information about the lists into dynamic here: [how to make a variable in the list? | http://asktom.oracle.com/pls/asktom/f?p=100:11:0:P11_QUESTION_ID:210612357425]

  The view was created with quotes around column names, so that they are case-sensitive. You need to either modify your trigger double quote column names, or rebuild the view without the quotes. Personally, I'd go with changing the display.

  If your DB is 11g, you can try this

  CREATE OR REPLACE TRIGGER  "TAKEOVER_USERS_T1"
  BEFORE
  insert on "TAKEOVER_USERS"
  for each row
  begin
  :NEW.TAKEOVER_UID:=TAKEOVER_UID.nextval;

  If 10g or more...

  CREATE OR REPLACE TRIGGER  "TAKEOVER_USERS_T1"
  BEFORE
  insert on "TAKEOVER_USERS"
  for each ROW
  BEGIN
  SELECT TAKEOVER_UID.NEXTVAL INTO :NEW.TAKEOVER_UID FROM dual;

  WEBUTIL also contains javabean. I don't know why you have this restriction, I would say that you do not succeed without any java bean.

• So, what new features actually exist in the first CC vs CS6?

  Nothing new to this point? I know that a comparison function will be difficult over time since the features will be released regularly, but I'm curious. I struggle, I can upgrade CS5 to CS6 for $525 now and be good for the next few years, or at least until I see what new features are coming that miss me. Basically, CS6 upgrade is cheaper than CC's of 18 months so that one would expect to be missed on?

• reading data from a variable, separated by "|" and insert into the table

  Hi experts,
  
  I have a file on FTP and I read the file. Now what I have to do is to separate the data and insert them into a table. I have already created the table with the required fields.
  
  How can I get data from str?
  
  code below
  
  declare
  File1 UTL_FILE. TYPE_DE_FICHIER;
  VARCHAR2 (1000) filename: = "GTECHFILES";
  Long str;
  Start
  File1: = UTL_FILE. FOPEN (filename, 'agent_dump_csv.rep', 'r', 32767);
  loop
  UTL_FILE. GET_LINE (File1, str);
  -dbms_output.put_line (' value is :'|| to_char (STR));
  end loop;
  UTL_FILE. FCLOSE (file1);
  exception
  When no_data_found then
  dbms_output.put_line ("END OF FILE");
  UTL_FILE. FCLOSE (file1);
  while others then
  UTL_FILE. FCLOSE (file1);
  dbms_output.put_line (' ERROR: ' |) SQLCODE |': ' | SQLERRM);
  end;

  You must use ' \ [^ |] +' like regexp:

• 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

  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.

• Interactive report Bind variable not working do not?

  Hello
  
  I'm new to APEX and try to find how to use APEX of interactive reports with bind variables. So, I created one with the following query:
  
  SELECT i1.if_bic_code, b.bicname, count (*) NTC
  OF IF_DATA i1, bic b
  WHERE i1.if_bic_code = b.biccode (+)
  AND i1.insert_date BETWEEN: P40_X1 AND: P40_X2
  I1.if_bic_code GROUP, b.bicname
  
  The report is supposed to show a number of comments by the bic_code (= bicname) of the IF_DATA table for the specified period.
  
  These 2 bind variables are actually 2 Articles in the same region, with the help of a DatePicker for them. They have no initial values. Thus, the report displays initially no record. After either by using the date picker or manually enter values in these 2 points and pressing go button doesn't always display no line. Am I missing something here? It seems that the query again to the database, or the bind variables do not take the values entered for them.
  
  TIA

  Hello

  If you are the Go button that appears on the interactive report action bar, you must add in page elements names that must be saved when you do this, as the page itself is not subject to (which is the normal action that saves your dates).

  To do this, change the attributes of the report and go to the bottom of the page. You should see a section attributes advanced with a parameter "Page to go". In this, enter:

  P40_X1,P40_X2
  

  -C' is a list separated by commas to names of page elements that you saved when you click the Go button

• Bad connection variable? I'm doing a host variable.

  Okay, so I said a global variable:
  
  VARIABLE g_total NUMBER
  
  and I want to use this variable to store the results of a stored procedure (I reduced my code to focus on the problem area):
  
  CREATE OR REPLACE PROCEDURE my_procedure
  (p_price IN m_movies.price%TYPE
  p_quantity IN m_cart.quantity%TYPE)
  IS
  BEGIN
  : g_total: = p_price * p_quantity;
  DBMS_OUTPUT. Put_line ("the order total is: ' |: g_total");
  END;
  /
  
  
  After all this, I get an error "bad bind variable g_total ' for the two lines I use it inside the procedure. What the heck is a variable binding? I use a host variable. (I think). If this has nothing to do with the fact that I can only give a very generic NUMBER data type to the host variable? Help, please!

  It's not the way it will work. You cannot create choice with lie (as you saw).
  You had rather code like this:

  SQL> VARIABLE g_total NUMBER
  
  SQL> create or replace procedure my_procedure (p_price      in     number,
                                            p_quantity   in     integer,

  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.

  Fact exits of the indexes on the tables and stats are updated...?
  Try to predict explain it. ??

• See criteria and bind variables

  Greetings experts,

  I use JDev, version: 11.1.2.3.0

  Recently, I came across this situation. I created a variable binding (in VO), which is used inside a criterion for the VO even. This criterion to display is called within a method that is declared within a class of java of implementation of AppModule (which is exposed on the Client Instance), and through a managed bean I supply the parameter required to initialize the variable binding (and then get the results). This works fine, and the page that uses the domain controller for this appmodule runs without error.

  The point is that I have the same VO, used inside an another appModule (and another page uses, it's DC). I need to use this variable binding in this case, but if I click edit on this VO second, inside the second presentation of appModule interface, I can see that the criteria for the view, is in the "Available" tab, but in the section 'Setting bind' it shows the binding variable said first.

  I am as a matter of fact, receiving and error on this second page if I do some operations, saying this:

  Caused by: java.sql.SQLException: try to set a parameter name that does not intervene in the SQL: partyNum

  at oracle.jdbc.driver.OraclePreparedStatement.setNullAtName(OraclePreparedStatement.java:5384)

  at oracle.jdbc.driver.OraclePreparedStatementWrapper.setNullAtName(OraclePreparedStatementWrapper.java:1451)

  at oracle.jbo.server.OracleSQLBuilderImpl.bindParamValue(OracleSQLBuilderImpl.java:4695)

  at oracle.jbo.server.BaseSQLBuilderImpl.bindParametersForStmt(BaseSQLBuilderImpl.java:3673)

  at oracle.jbo.server.ViewObjectImpl.bindParametersForCollection(ViewObjectImpl.java:21459)

  at oracle.jbo.server.QueryCollection.buildResultSet(QueryCollection.java:1197)

  SQL error in the preparation of the statement.  Instruction: SELECT PartiesContracts.CONTRACT_IDCONTRACT, PartiesContracts.PARTY_TYPE, PartiesContracts.PARTY_NUM, PartiesContracts.ROLE PARTIES_CONTRACTS PartiesContracts WHERE PartiesContracts.CONTRACT_IDCONTRACT =: Bind_Idcontract

  (The binding variable is called, partyNum)

  My question is, can I do to avoid using this variable to link on the second page of appModule only? It seems to be called always regardless the fact if I call the appropriate support bean method that triggers the initialization process.

  Thank you for your time.

  Have you defined the binding variable 'partyNum' as requires it? In this case, you need to specify every time. You can set the variable as not mandatory and it might work.

  The solution would be to set another VO with the same base, without the "partyNum" bind variable and VC and use in the other AM.

• Procedure with an unknown name or the amounts of the bind variable.

  Hey gurus,
  
  I hope someone out there can point me in the right direction.
  
  I write a PL/SQL function that receives an unknown number of bind variables in the client.
  I use Apex 1.1 earpiece to set up a model of RESTful resource for a x-www-formulaires-urlencoded body POSITION.
  
  If the client publishes the following body: * "title = M. & fname = John & lname = Smith" * "
  
  My PL/SQL procedure automatically receives the bind variables which is placed by the following:
  : title: = "M";
  : fname: = "John";
  : lname: = 'Smith ';.
  
  Now my limit is that the required design uses the metadata to define the structure of data of the end-user.
  So in reality the body of MESSAGE I get more like this: * "M. = 120 & 121 = John & 122 = Smith" * "
  
  So my PL/SQL procedure receives:
  : 120: = "M";
  : 121: = "John";
  : 122: = 'Smith ';.
  
  I can query the metadata tables to anticipate what bind variables can be present at the execution,
  but this can change depending on the resource ID with the body of the MESSAGE at the time of the request.
  
  My first attempt was to be a loop expected elements and run an EXECUTE IMMEDIATE likes:
  
  for c_record_items in
  (select field_id in the tfields where record_id =: id) loop
  EXECUTE IMMEDIATE ' begin update_item ('|: field_id |', :'|| field_id |'); end;';
  end loop;
  
  But unfortunately the EXECUTE IMMEDIATE fails because the binding variable is not declared; It requires the USING clause.
  Which I can't think I can code the amount or value in...
  
  I started dabbling in the DBMS_SQL package but I still have to think of a way I can fix this problem.
  
  There are experts out there who can direct me in the right direction?
  Very much appreciated.

  I have a lot of procedures where I accumulate the number of bind variables.

  My approach has been to load each variable binding in an associative array and maintain a counter of the number of bind variables.

  Finally, there is a great if then elsif endif block which is actually

  if v_binds = 0
  then
       execute immediate ;
  elsif v_binds = 1
  then
       execute immediate  using bind_array(1);
  elsif v_binds = 2
       execute immediate  using bind_array(1), bind_array(2);
  elsif ...
  end if;

  Re: USING Dynamic Clause?

  Later, I discovered that you could do something like the following:

  Either of these approaches to solve your problem.

• Performance tests: bind variables

  When you write a SQL for the application, I want to do some performance testing of SQL before providing to JAVA developers. I understand that I need to test using bind variables, can someone guide me how do? What are the best tools out there to achieve? Please provide some guidance. Thank you!

  Rinne says:
  I read more about bind variable and I can test the use of bind variables. I understand that testing SQL using bind variables is a closer representation of the real world. Even when queries have large tables, the performance would be similar if I run the query using literals twice (to avoid hard analysis) compared to tests with bind variables? I am trying to understand more thoroughly the need for tests with bind variables. Why we take more time than the other? Thank you!

  The main thing is that the opimizer will / can do if bind variables different optimization techniques are used or not.
  There are two contradictory effects its regarding the binding settings.

  Effect 1: Reuse of cursor
  If the same is done again and again and again. Maybe different sessions. Then using binding settings is essential. Why? Because the same cursor can be reused, which saves a lot of time for analysis. This occurs mainly in OLTP systems. The idea behind this is that to do the same action, just for a different ID (ID in order for example) will result in an identical implementation plan.

  The result: Faster analysis time and less consumption of memory, because the same cursor can be resused between different sessions.

  Effect 2: Correct assumptions

  According to a filter expression, some using the value of the OBC will make an assumption based on statistical data the number of rows is returned because of this expression and the value.
  Speculation between a literal value and a bound value may be different. In many cases exist technical opimization (bind peeking etc.) to the same literal conjecture binded proposal.

  But there are exceptions, for example a condition such as the following will result in different estimates

  column between 10 and 20
  

  column between :P1 and :P2
  

  There are as well other effects.

  Result: The CBO can make assumptions better if literals. But most of the cases the proposal is identical.

  Conclusion: Literal values are useful if you do large queries where the output size depends strongly on the parameters provided, and where you run that very few of these (OLAP) queries.
  Binding settings are usfull when the same execution (OLTP) need a grand plan number of queries.
