• How to create a procedure for REF CURSOR output with any WHERE clause?

  I have a requirement like this: I have a huge question that need to reuse in my code over 10 times. This SQL has about 50 lines. Here for these 10 odd times sometimes changes in WHERE clause (columns are the same). So I can't create a view as SQL is not static.
  
  I thought to write a procedure with a para of WHERE_CLAUSE entry. I pulled out a refcursor sys by adding where clause. But I can't do it because you cannot add a clause like this where clause.
  
  i.e.

  PROCEDURE dynamyic_query (p_where_clause IN VARCHAR2, p_out_query OUT SYS_REFCURSOR ) IS
  BEGIN
  
    OPEN p_out_query FOR SELECT ......... FROM table WHERE || ' ' || p_where_clause;
  
  END;

  The foregoing gives an error.
  
  How to handle such a situation? Any help would be greatly appreciated.

  Looks like you can only set column_name =: z, column_name =: values of type y. You can not it seems to replace it with no WHERE CLAUSE?

  A bind variable, such as: it, represents a single value.
  If: is the VARCHAR2 '1 = 1', then

  SELECT tname FROM tab_test WHERE tname LIKE '%ABS_V4%' AND :y
  

  takes the value

  SELECT tname FROM tab_test WHERE tname LIKE '%ABS_V4%' AND '1 = 1'
  

  I think you want something like this:

  CREATE OR REPLACE PROCEDURE FORMS_TEXT_DYN_SQL_TEST

• Need help with dynamic where clause.

  Hello world.  I'm kind of a novice with PL/SQL, so please be patient with me.  I am building a web application using Weblogic Oracle 11 g and Oracle database.

  To make a long story short, I need to generate the complex dynamic WHERE clause.  I don't know what will be the name of the column or the operator of comparison or the value will be until the moment of execution.

  I'm not 100% certain, but I think I need to use dynamic SQL statements.  Unless there is a better way to do it.

  I'm sure that using dynamic SQL opens me up to SQL injection attacks if I use simple string concatenation.  I would like to use bind variable if possible.

  In any case, it seems like trying to build a dynamic where clause does not seem to work as I want it would be...

  bv1 := 'colA = 5 and colB >= 9';
  
  query_str := 'SELECT * FROM view WHERE :bv1';
  
  OPEN CUR FOR query_str USING bv1;
  

  The code above pours out when I try to run it.

  Is there a way to build dynamic where the provisions without the use of concatenation of simple string that leaves me open to attacks by SQL injection?

  Thank you

  Hello.  I have read briefly upward on things, you suggested, but it seems a bit abstract for me since I was a novice.

  Can you give us an explanation or an example of how to use it to accomplish what I need to do?

  Do ypu really plan create a query with a WHERE clause that contains a predicate for all possible columns?

  Variable bind offer performance when the same query is executed several times with different values for bind variables.

  Select * from emp where empno =: v_empno

  After the first run Oracle will always be this query in the library cache. The next running can use the version of the cache even if the bind value is different.

  Select * from emp where empno =: v_empno;

  Select * from emp where ename =: v_ename;

  Select * from emp where sal =: v_sal;

  Each one is a DIFFERENT query. Yes - each of them uses a variable binding, but queries are different.

  So, if your username select EMPNO, an '=', and a value from the first query can be executed. But the next time that the user can select the ENAME column so that 'stored' first request may not be used given that the query does not match.

  The third time your user selects SAL so none of the first two queries can be used in the library cache. The use of bind variables gives performance during the SAME QUERY is used multiple times with DIFFERENT values for the variable binding. Oracle is not to analyze the hard query everything simply because the VALUE is different.

  So bind variables do not help you if most of the queries were completely DIFFERENT sets of predicates. And SYS_CONTEXT will not help either since that simply provides a way to define binds the values of the variables.

  Just for the simple example above, there are at least SIX possible combinations of columns that could choose your user name: empno, ename, sal, empno ename, empno & sal, ename & sal

• XMLTable with a WHERE clause?

  I have a table that looks like this race under Oracle 11.2.0.3.4:

  He played really bad, and then I realized that he returned each row in the table for each iteration of the query. Is XMLExists the only way possible to return a single line, assuming that ISBN_NBR and PROD_ID are unique? Can the clause WHERE cannot be used as a discriminator at all?

  Hello

  Right; the order in which the columns appear in the SELECT clause has nothing to do with the lines that are in the result set.

  In fact, unless you say SELECT DISTINCT , I don't think there's anything (except to trigger an error) you can do in the SELECT clause, which would change the lines are selected.

  Published by: Frank Kulash, November 20, 2009 12:45

  Sorry, I misread the question. You may have about the order of the conditions in the WHERE clause, not the SELECT clause.

  The answer in short is the same:
  Right.

  Unless you mix ANDS and ORs (no one should ever do and that you are not), the order of the conditions will make no difference in the results.

• How to set a null column in a where clause clause involving a statement box

  In oracle APEX, I a (selection list) element called: P32_STATUS. It contains two values of interest (for this discussion): 'Available' and 'checked '. In my report, I have a column called vc_status that contains two values: "Checkbox" and NULL. In my application I want to use a case statement in my where clause similar to the lines of

  where

  .

  .

  .

  AND (vc_status = CASE WHEN: P32_STATUS = "Checkbox" THEN : P32_STATUS )

  WHEN : P32_STATUS = 'Available' THEN NULL END)

  The 'box' filtering works but the filtering to try to vc_status the NULL value does not work. Can someone help me? Thank you!

  (P.S. My intuition says that there because I can not put vc_status = NULL, but I must say that vc_status IS NULL... However, I don't know how to do execution IS ZERO inside a CASE statement)

  Hello

  Your intuition is right...

  In Oracle NULL is a bit special:

  NULL = NULL is false

  NULL <> NULL is false

  Thus, instead of the parameter a NULL value in the CASE WHERE there is just set a value on the other side:

  NVL (vc_statut, 'Available') =: P32_STATUS

  That's all! Simple, clean and functional

• Help with MySQLI WHERE clause

  I am trying to retrieve records from a table of unique composition based on the following criteria:

  -members belong to 2 different associations (coded: Association = 1 or 2)

  -Some members have no postal addresses (coded: adresse_rue) and will not send mail.

  -Some members Association = 1 don't you mail (coded: D or V or W, X or Z)

  -No member of the Association 1 with cur_bal_2 = < gets 10 mail

  -No member of the Association 2 with cur_bal_2 = <-1 get mail

  -cur_bal_2 field is a numeric value in the table.

  I tested

  WHERE (Mbr_Scat = 'P' AND Association = 2 AND adresse_rue <>' ' AND cur_bal_2 > = - 1) by itself results accurate/w

  WHERE (Mbr_Scat <>had ' AND Mbr_Scat <>'V' and 'W' AND Mbr_Scat <>'X' <>Mbr_Scat ' AND cur_bal_2 >-20 AND adresse_rue <>' ") by itself, results also w/accurate

  But-

  When I combine the above to:

  WHERE

  (Mbr_Scat = 'P' AND Association = 2 AND adresse_rue <>' ' AND cur_bal_2 > = - 1).

  OR

• Problem with a Where Clause in report

  Hi all
  
  I have a simple report on the EMP table with a form of parameter to select employees of a particular or all departments.
  It works fine if I'm in one or all the departments in the report. The SQL code for the report is the following:
  
  SELECT
  EMPNO,
  ENAME,
  HIREDATE,
  SAL,
  DEPTNO
  Of
  EMP
  WHERE
  DEPTNO LIKE "%" | : P68_DEPTNO | » %'
  
  Now, I have added another element of setting labeled "category". If you select the category 'OFFICE', she must return employees of departments 10 and 20, if selected from category 'FIELD', he has to return employees to Department 30 and 40. But if you select the category ALL then he must return the employees of all departments.
  
  Anyone would be able to advise me on the correct approach to achieve the above?
