dynamic instruction in where clause?

Similar Questions

• Case instructions within a Where clause clause

  Hello group,

  I know this has been asked several times, but I do not enter simply to a tuition assistance box in a WHERE clause.  So I need help:

  My current WHERE the clause reads:

  A16. FULL_DATE between (SELECT (TRUNC (SysDate - 8)) From Dual) and (select (TRUNC (SysDate - 2)) double)

  However, I need to 'automate' a bit, based on the current time/day of the month.  I need my instruction box to say:

  (Case when to_char (sysdate-3, 'mm') <>to_char (sysdate, 'mm')

  then the a16. FULL_DATE (between SELECT (trunc (ADD_MONTHS ((LAST_DAY(SysDate-3)),-1)+1) and (SELECT (add_months (trunc(SysDate-2)-1)) of double)))

  Of another a16. FULL_DATE between (SELECT trunc (ADD_MONTHS ((LAST_DAY (SysDate)),-1)+1) From Dual) and (select (TRUNC (SysDate - 2)) From Dual)

  However, I have an error on "Else".  Can someone explain what is the problem and how to fix it?  I tried both 'then' and 'Else' syntax and both will run individually.  So I'm quite sure that he does not like my CASE statement in general.

  In advance, thank you for your help.

  I can't tell what your business logic, so here's a simple example of an instruction box in the where clause:

  SQL > select *.
  2 double
  3 where dummy = case when extracted (sysdate months) = 9 then 'W '.
  4 Once extracted (sysdate months) = 10 then 'X '.
  When 5 extract (month from sysdate) = 11 then 'Y '.
  6                      else 'Z'
  7                 end
  8;

  How get the desired results of your data depends on the desired results and your data.  What do you do?  (I can't tell just by looking at the aat code that do not do).  After CREATE TABLE and INSERT statements for some sample data and a couple of sets of parameters (variables such as p14_zone) and the exact results that your choices in each set of parameters, given the same sample data.

  Check out the Forum FAQ: Re: 2. How can I ask a question on the forums?

  CASE expressions are generally not useful in a WHERE clause.  CASE expressions are a convenient way to IF-THEN-ELSE logic of the places where you can't do anything other than (the SELECT clause), but WHERE the clauses allow IF-THEN-ELSE logic in any case

  Maybe you want something like

  WHERE MERGE (: p14_zone,: p14_zone_2,: p14_zone_3,: p14_zone_4) IS NULL

  OR IN i.compute_zone (: p14_zone,: p14_zone_2,: p14_zone_3,: p14_zone_4)

  It returns TRUE if all 4 parameters are set to NULL.  If 1 or more of them are not NULL, then it will return TRUE if i.compute_zone is equal to one of them.

• 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

• dynamic where clause ofa

  Dear all,

  I have a problem in the dynamic where clause in the OPS.

  I have a VO query as below:

  SELECT desc, ccuid, containid, XXXTMP conainline

  I'll put whereclause as below:

  VO.setwhereclause ("containid '101' =" + "order by containline desc")

  so the question is request forms as below:

  SELECT desc, ccuid, containid, XXXTMP conainline

  (where containid = '101' containline desc order) -query gives question, adding the command from the inside of the caliper

  Ideally, order by clause should come outside of the Stirrup.

  so, how do I do order by clause order side where clasue or how do I remove the stand before the where clause. So I need the query as below:

  SELECT desc, ccuid, containid, XXXTMP conainline

  (where containid = '101' containline desc order)

  SELECT desc, ccuid, containid, conainline from XXXTMP where containid = '101' containline desc order

  or

  SELECT desc, ccuid, containid, XXXTMP conainline

  (where containid = '101') order by containline desc

  Thank you

  Hello

  Solution 1-

  You can use "setOrderByClause (containline desc);" so that it will get out of Where clause.

  Solution 2-

  Instead of dynamically add Whereclause, you can bind the variable as below-

  Query in VO-

  SELECT desc, ccuid, containid, conainline from XXXTMP where containid =: 1 containline desc order

  
  

  In VOImpl-
  

  public void initQuery (String variable)

  {

  clearCache();

  setMaxFetchSize(-1);

  setWhereClause (null);

  setWhereClauseParams (null);

  setWhereClauseParam (0, variable);

  executeQuery();

  }

  Vall of this VOImpl method, and pass the variable value. It will work according to your requirement.

  Thank you

  How can I achieve this.
  
  
  
  Thank you
  CSK

  Try

  vo.setWhereClause ("IN vendor_id (" + vendor_id_qry + ")" ");

  vendor_id_qry is the query that retrieves the list of provider IDS. You don't need to put the vendor column id as whereClauseParam unless you want to have IN the clause in your query of VO and pass the list as 1,2,3 values to the parameter.

• Interactive report dynamic where clause

  Hello!
  
  Is it possible that a report interactive sql source can have a where clause clause that is built dynamically?
  
  Marc

  Marc:

  You could empty the record-ID set in a collection of the APEX.
  Change the IR query to add a join for this collection. Something like

  select c1, c2,c3...
  from  main_tab a, apex_collections b
  where b.name='RECORD_IDS'
  and a.pk_col=b.to_number(c001)

• Add where clause dynamically

  Hi Experts,

  I have a VO with query like select * ministries dept, emp where dept.dept_id = emp.dept_id group... by order of dept.dept_id employees

  At runtime, I need to add where clause with (and in dept.dept_id (select dept_id from table2))

  I tried to use the vo.setWhereClause () method. But it does not work

  Is there another solution?

  I use Jdeveloper 12.1.3

  Thanks in advance.

  There are various possible solutions for this. You can either use setQuery that defines the entire sql statement. However, you then need to delete where condition adding yourself too.

  Or you use viewCriteria as explained in this blog http://www.ahsanscorner.com/content/2015-11-16-1942-simulating-sql-clause-adf-viewcriteria-api.

  Another approach is described by this blog Jet binary: using bind variable for SQL statements with the paragraph who uses a SQL table to build the in clause.

  Published by: user10941925 on March 4, 2012 22:31

  Hello

  CASE expressions return a single value, for example a VARCHAR2. They do refer to code fragments.

  You usually don't need (or want) an expression BOX in a WHERE clause, or any other condition. I think that you were trying to do the equivalent of:

  AND     (     (:KAPCO = 'KAPCO'          AND cla.CLASS_NAME       LIKE '%KAPCO%')     -- Don't you want UPPER on this line?
       OR     (:KAPCO = 'NON_KAPCO'           AND UPPER(cla.CLASS_NAME) NOT LIKE '%KAPCO%')
       OR     (NVL (:KAPCO, 'ALL') = 'ALL'       AND cla.CLASS_NAME IS NOT NULL)
       )
  

  If you would care to post some sample data (CREATE TABLE and INSERT statements) and the results desired from this data, I was able to test this.

  Is there a way to make / calculate a where clause clause in a user defined report according to the value of some bind variables?
  I am trying to remove where the terms of my application if the binding variable is not defined.
  previously, I did something as

• Using a CASE statement in 'IN' where clause clause

  Hello

  I have a form that users see after they connect with a few items and they type or select values based on the element type. All reports in the application use these values of PAGE 1 in where clause to filter the lines.

  One of these question is "Quarter".  I have a group of radio buttons on the PAGE 1 on the P1_QTR point.

  I need to provide users a way to take the last 4, last 3, last 2 or current quarter and I need to dynamically build a clause WHERE the interactive report based on the selection in the form.

  I am trying to use the CASE as shown below and get the syntax error.

  AND QTR to (when BOX: P1_QTR = 'CURRENT' then ("T4"))

  When: P1_QTR = "LAST" then ("Q3")

  When: P1_QTR = 'LAST TWO' then ('Q3, "Q4")

  When: P1_QTR = 'LAST THREE' then ("Q2", "Q3,' T4 ')

  another ("T1", "T2", "Q3,' T4 ')

  END)

  How can I achieve this?

  Following a simple logic, try

  and QTR to

  (

  Select 'T4' double where: P1_QTR <> 'LAST '.

  Union of all the

  Select 'Q3' to double where: P1_QTR <> "in PROCESS".

  Secondly, the issue I'm facing is I'm trying to implement a query with three sous-sélections them in the (see image below) WHERE clause. I don't know what is the best way to implement something like this.

  I have implemented this by creating a display object and add a view criteria. I put the whole SQL fragment in the view as a literal value criteria. Is there a better (or best?) approach to implement something like this?

  This implementation is a problem is because as well as query tests out fine when I click on explain Plan even recognized that there is no bind variables in subqueries and allows me to.

  When I run this test by the tester of AM, that it fails to recognize and define the binding (projCategory) variable that appears only in subqueries. All your comments and/or help is very appreciated.

  

  Thank you

  Vladimir

  Vladimir, there is something wrong in the view Definition of criteria dialog box. The button "explain plan...". "running the whole statement generated (as a string) and returns the result. The entire statement is valid and returns the correct result. However, the view criteria, when it is running in the application work differently. Here the literal that you entered is not passed as a string, but the framework does something internally with her (it is necessary to do things as in the research of memory and other things). If you run the criteria to view in the app Tester I get

  SQL error in the preparation of the statement.  Instruction: SELECT Employees.EMPLOYEE_ID, Employees.FIRST_NAME, Employees.LAST_NAME, Employees.EMAIL, Employees.PHONE_NUMBER, Employees.HIRE_DATE, Employees.JOB_ID, Employees.SALARY, Employees.COMMISSION_PCT, Employees.MANAGER_ID, Employees.DEPARTMENT_ID from employees WHERE (((Employees.SALARY< :vc_temp_1="" )="" )="" )="" ):="" ora-01722:="" invalid="">

  Accordingly, for the display criteria

  employes.salaire< (select="" max(e2.salary)="" from="" employees="" e2="" where="" e2.department_id="">

  As you can see the literal is passed as: vc_temp_1 and my binding variable is not visible at all. You can open an SR and ask for the support of working on it. I guess that they do not see a bug here as help for the dialog box says:

  Literal

  Select when you want to provide a value for the attribute, or when you want to set a default value for a lookup field specified by the user for a search query-by-example form.

  When the criteria of view defines a search query for the user interface form, you can leave the field blank. In this case, the user will provide the value. Alternatively, you can provide a value that will act as a default value to the field search that the user will be able to substitute. This entry can include wildcards * or %.

  When the attribute is of type Date, specify the value of the date in the format YYYY-MM-DD; for example, to December 16, 2010, enter 2010-12-16.

  Here, it tells you that a value is expected. Your sub query is not interpreted, but is simply converted to the appropriate data type. In my example, I get an invalid number as expected.

  So I guess my suggestion to use a custom sql statement stands.
