• Case with where clause - ORA-00920: invalid relational operator

  Hi all, when I try to run the following query, I get the following error...

  ORDER OF CONCAT (year, number 'months') / / DESC

  The problem is the number 'month' - you cannot give an "ACE" alias for an expression in a where clause clause.

  You have not really given any condition, that a set of translations of period in a number.

  Also, you didn't say what you're trying to do.

  Maybe you want to:

  SELECT concat (year, period)

  OF DD_ACTUALS_FACT

  WHERE something

  ORDER OF CONCAT (year, period of the CASE

  WHEN 'JAN' THEN '01'

  WHEN 'FEB' THEN '02'

  ERROR at line 1:

  SQL> 
  

  Reason is first selection from the first filters view (find out where clause) out of the non-numeric values and then only apply to_number. When the second select is run optimizer merges the view definition and where would adopt becomes:

  where where code = 'number '.
  and to_number (val) > 100

  Since there is no order of predicate, it happens that to_number (val) > 100 is applied first, and he obviously fails.

• Question about the order of evaluation of the clause WHERE CLAUSE when the Oracle OF the syntax used to join tables

  Hello

  Oracle version: 11.1.0.7.0 - 64 bit

  I read the documentation online at joins. The page is avialable here: joins at

  My question is about the join order of evaluation of the conditions in clause and the conditions of those

  are not the join conditions and are placed in the WHERE clause.

  Consider the following pseudocode

  SELECT

  T1. Col1,

  T2.Col1

  Of

  Table1 t1 LEFT OUTER JOIN table2 t2

  WE

  (condition_expression1)

  WHERE

  (condition_expression2)

  Is it correct to say that if there is no column on the status of join (condition_expression1) in condition_expression2, then condition_expression2 is executed before condition_expression1? In other words, oracle always trying to filter based on the WHERE clause individually each table as much as possible before joining them based on the conditions on the article?

  Thanks in advance,

  The reverse is actually closer to the truth, but we can't really make general statements like that.

  SQL is not a language of the proceedings.  Looking at the code SQL, we could say that the code does, but we cannot say much about how that code it.  In other words, SQL is a language that describes the results you get, not the way to get them.

  The optimizer will do everything what he thinks is faster if it does not change the results.  If any order in which they are applied (in outer joins or CONNECT BY queries, for example), then think of the join is done first, and the value of the WHERE clause is applied to the result of the join.

  Here is a query looks very much like you posted:

  SELECT d.deptno

  e.ename, e.sal

  OF scott.dept d

  LEFT OUTER JOIN scott.emp e ON e.deptno = d.deptno

  WHERE e.sal > = 3000

  ORDER BY d.deptno

  ;

  Output:

  DEPTNO ENAME SAL

  ---------- ---------- ----------

  10 KING 5000

  20 FORD 3000

  20 3000 SCOTT

  The scott.dept table contains deptnos 30 and 40; Why are they not in the result set?  The query behaves as if the outer join is made first (production 15 rows), then the WHERE clause has been applied.  All lines with deptno = 30 had sals down han 3000 and all single line with deptno = 40 was NULL in the sal column, then these lines are excluded (as well as other lines of deptnos 10 and 20), and only 3 lines above are left.

• Question about WHERE Clause

  Hello

  I'm doing a conditional clause where clause displays the lines in a report.

  The desired control is date of two fields (CIC and announcement) must all be virgins or someone not be an 'Admin' (taken from a global variable stored on connection) for her to no display.

  Here's what I have:

  WHERE (DATACOLLECT. ANNOUNCEMENT_OF_DEAL_SIGN IS NOT NULL AND DATACOLLECT. CHANGE_IN_CONTROL IS NOT NULL) OR UPPER(:F19959_USER_ROLE) = "ADMIN".

  During the test of this query, it hides a field with ONE of the two dates being blank and which is not desirable.

  I also tried to write it like this and got an error of analysis for an invalid relational operator:

  WHERE (DATACOLLECT. ANNOUNCEMENT_OF_DEAL_SIGN AND DATACOLLECT. CHANGE_IN_CONTROL IS NOT NULL) OR UPPER(:F19959_USER_ROLE) = "ADMIN".

  Any help would be greatly appreciated. Please let me know if I need to clarify.

  I take what I said back.  Your requirement of "double negative" is odd

  DO NOT SHOW: where (X is null and Y is null)

  translates

  Show: where not (x is null and Y is null)

  WHERE NOT (DATACOLLECT. ANNOUNCEMENT_OF_DEAL_SIGN is null AND DATACOLLECT. CHANGE_IN_CONTROL IS NULL) OR UPPER(:F19959_USER_ROLE) = "ADMIN".

• Question of WHERE Clause.

  All, I was just doing some checking at random and came across the following query

  SELECT * FROM emp WHERE +empno > 0;
  

  My question is that oracle runs the query above without any error. What is the use of such expressions in where clause and why the compiler does not throw error for these?

  I've never met such scenario. Just tried your query and it works. The reason is below.

  Look at what makes this request.

  SELECT - empno FROM emp;

  OUTPUT:

  -EMPNO
  ----------
  -7369
  -7499
  -7521
  -7566
  -7654
  -7698
  -7782
  -7788
  -7839
  -7844
  -7876

  -EMPNO
  ----------
  -7900
  -7902
  -7934

  14 selected lines.

  So you might see if you add a minus sign before the name of the column, it converts only for negative values.

  So, even if you add a sign "+", since these are positive values (> 0), your condition succeeds and gives the result. See what would happen if you used - empno in which your condition.

  SQL > SELECT * FROM emp WHERE empno - > 0;

  OUTPUT:

  no selected line

  Hope you clear how it works.

• WHERE clause order ox performance question

  I want to write a SELECT statement with the following condition
  
  ... WHERE (branch = 'main') AND (type = 1) OR (AND the costs-1 = 2).
  
  My question is
  
  < 1 > yoyu can use parentheses within a WHERE clause
  
  < 2 > how you would write such a clause as above if you cannot use parenthesis
  
  Thank you

  Hello

  Yes, you can have parentheses in a WHERE clause.
  I highly recommend to use when you need to use both AND and or in the same WHERE clause, since

  WHERE  (    x
          AND y
          )
  OR      z
  

  is not the same as

  WHERE   x
  AND     (   y
          OR  z
          )
  

  As others have said:

  ( charge -1 AND charge = 2 )
  

  will cause a compilation error.
  Here's the syntax valid and quite reasonable (although somewhat obscure):

  WHERE     (     branch = 'main'
       AND     type    = 1
       )
  OR          (     charge != -1
          AND     charge !=  2

• Implementation of subqueries in the WHERE clause

  Hi all

  First of all, here are the technical info:

  Oracle JDeveloper 12 c 12.1.3.0.0

  Studio Edition Version 12.1.3.0.0

  Build JDEVADF_12.1.3.0.0_GENERIC_140521.1008.S

  Version of the component

  Oracle IDE 12.1.3.0.41.140521.1008

  Java (TM) Platform 1.7.0_51

  Support versioning 12.1.3.0.41.140521.1008

  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.

• Binds a parameter in WHERE clause throws error (ORA-00920)

  Good day to you all.  Hope everything goes well.

  Ok.  Here's the deal.  I am trying to bind a parameter in a where clause clause, but I continue to get the error invalid relational operator (ORA-00920).  It seems as if Oracle is looking for a correct syntax before you pass the variable (bind value).

  For example:

  SELECT LAST_NAME, FIRST_NAME FROM MYTABLE
  WHERE OBSOLETE IS NULL
  and :P_MY_BIND_VALUE
  

  What is the right way to get around this?

  Thanks for all your help!

  I use simple SQL.  The variable binding will be used in the APEX and an item that is based on a LOV with where condition stored there.  Make sense?

  Logic you want... doesn't have a sense of how you try to do.

  Bind variables are for the passage of the 'values' to a question, only not for the passage of the SQL statements or sections of objects such as the names of tables etc.  It is not a substitution string such as the use of '&' in SQL * more and should not be treated this way.

  If you could provide more details on exactly what you're trying to do (some data would help) then perhaps we could tell how best to go about this.

• NVL selection list does not not on the place where clause in query

  Ok. APEX 4.2...

  Im having problems with my selection lists and NULL values... I see that it has come time and time again...

  I have a tabular presentation, with a query based on a selection list.  The selection list has the ability to '- Show All -'... The value of the selection list is a number, and the display is words...  (for reference the LOV query is: select status, batch from pmt_stat_lookup by 1)

  Initially I had problems with null and invalid numbers like ' display Null = 'Yes' and the problem of null % ', so have used the code in this blog to remove the NULL values... Display Null = & amp; #34; Yes & amp; #34; and the problem of null % | Inside Oracle APEX by Patrick Wolf

  Then in the application of my report, I have a where clause clause that checks the value of the selection list... WHERE batch = nvl(:P11_STATUS_SELECT,STATUS_ID)

  everything works almost fine, and I can choose a status, or I choose - see the All-, but the query will not include the lines where the State is null.

  (I also see that maybe I should be, use the case statement instead of the NVL on where clause, but not sure of the syntax. In addition, NVL was used somewhat in the different reports in the application...)

  For reference, the code of the old blog that I as a process page is:

  BEGIN

  FOR rItem IN

  (SELECT NOM_ELEMENT

  OF APEX_APPLICATION_PAGE_ITEMS

  WHERE APPLICATION_ID = TO_NUMBER(:APP_ID)

  AND PAGE_ID IN (TO_NUMBER(:APP_PAGE_ID), 0)

  AND LOV_DISPLAY_NULL = 'Yes'

  AND LOV_DEFINITION IS NOT NULL

  -change here

  AND LOV_NULL_VALUE = '% null | '%'

  )

  LOOP

  IF V (rItem.ITEM_NAME) = "% null | '%'

  THEN

  Apex_Util.set_session_state (rItem.ITEM_NAME, NULL);

  END IF;

  END LOOP;

  END;

• Very Urgent: Setting dynamic where clause for Popup list VO

  Hello world
  
  
  It is a very urgent requirement please help as soon as possible.
  
  
  I have a custom page in iSupplier. I created two supplier site, number of PO fields.
  
  Site of beg - choice of Message and PO number - Message LOV of entry
  
  
  I have a named VO under xxisupplier.oracle.apps.pos.home.poplist.server for site begging and xxisupplier.oracle.apps.pos.home.lov.server for PO number.
  
  I have joined these two VO AM homepage.

  AND poh.po_header_id = pda.po_header_id
  AND ai.invoice_type_lookup_code = al.lookup_code
  AND al.lookup_type = 'INVOICE TYPE'
  
  
  I am creating where cluase as below in CO
  
  
  
  If (vendor_id1! = null)
  {
  System.out.println ("vendor_id:" + vendor_id1);
  OAViewObjectImpl vo = (OAViewObjectImpl) am.findViewObject ("PO_LOV_VO");

  Here he works for the purchase order number but the where cluase does not work for Supplier Site. Please help as soon as possible.
  
  
  2 and also if supplier site to return multiple values then this field should show as messagechoice. If it returns a single value, then it should be the style text message
  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.

  Thank you

• 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'

• Trouble using a function in the where clause

  Hello
  
  I use a function that is located at ask.tom.oracle.com, which converts a long data type in a character. The function returns an error when it is placed in the where clause. The sql statement, the error message and the function of asking tom are listed below. Does anyone know how to fix this?

  Remove the '_' in the name of the function as below:

  AND OHM_PKG. GETLONG('EMPLOYEE_MEMO', 'FLDDATA', C.ROWID) AS "CDL % YES % '.
