• Setting in the WHERE clause of the query

  Hi all
  
  I have 2 tables.
  
  TABLE_A contains 10 million documents.
  TABLE_B contains 100 records.
  
  I associate myself with these 2 tables
  
  Here's a.ID left

  SELECT A.*, B.*
  FROM TABLE_A a, TABLE_B b
  WHERE a.ID = b.ID;

  Here's b.ID left

  SELECT A.*, B.*
  FROM TABLE_A a, TABLE_B b
  WHERE b.ID = a.ID;

  My question is what query will give better performance? I thought that, if we put the column in the table with a lower number of lines on the left, then it will be faster than the other.

  In current versions of Oracle, it does not matter in what order you sum-up your predicates in the WHERE clause of a query: they will be optimized/executed in a way even.

• Difference in WHERE clause VO and java class!

  Hello!
  
  I have VO:
  

  SELECT ADokumenti.A_DOKUMENTI_PK, 
         ADokumenti.APRAKSTS, 
         ADokumenti.DOKUMENTA_TIPS, 
         ADokumenti.DOKUMENTS, 
         ADokumenti.FAILA_VARDS, 
         ADokumenti.PASES_DATI_ID,

  WHERE ADokumenti.DOKUMENTA_TIPS = 'image/jpeg' or ADokumenti.DOKUMENTA_TIPS = 'image/gif' or ADokumenti.DOKUMENTA_TIPS = 'image/png'

  When I put the value of VO in java class

   vo.setWhereClause("A_DOKUMENTI_PK="+imageId); 

  WHAT result would be? Only java put where clause, or both?
  
  If one clause of java, and then how to add this: «A_DOKUMENTI_PK = "+ imageId vo?»
  
  Best regards, Debuger!

  Debuger,

  That's why I suggested that you create a view named criteria (with a variable binding) at design time. At runtime, you set the value of the variable binding and apply the criteria to view. The first link in the documentation I gave explains you quite well.

  You must use bind variables for five reasons:

  (1) performance
  (2) performance
  (3) performance
  (4) performance
  and
  (5) performance.

  Oh and

  (6) avoid errors of insufficient memory in the shared the database pool.

• Need help with CASE When statement in a Where Clause

  So I have a SQL (simplified for this forum)
  
  Select t1.*
  from table1, table2 t2 t1
  where t1.field1 = t2.field1
  and when t1.field2 is null then trunc (sysdate) < = trunc (t1.date1 + 17)
  of another trunc (sydate) > = end of trunc (t2.date2 + t2.date3)
  
  I end up getting an error ORA-00905: lack of keyword
  
  I'm sure that I just got something here involved.

  You can not make the comparison within the statement underlying case like this. Assuming you have appropriate data types, something like this should work

  Select t1.*
  from table1 t1, table2 t2
  where t1.field1 = t2.field1
    and ((t1.field2 is null and
          trunc(sysdate) <= trunc(t1.date1 + 17)) or
         trunc(sydate) > = trunc(t2.date2 + t2.date3))

• using case when statement or decode unfavorable in where clause

  Hi the gems...
  
  I have a problem in the following query...
  I try to use when case statement in where clause of a select query.
  
  
  Select cr.customer_name. ' - ' || CR.customer_number as cust_name,
  CR. Salary salary
  of customer_details cr
  where (case when ' > ' = ' > ' then ' cr.salary > 5000')
  When ' > ' = ' < ' then ' cr.salary < 5000'
  When ' > ' = '=' and then 'cr.salary = 5000'
  Another null
  (end);
  
  
  the expression in the when clause of the statement of the case, when comes from HQ and according to the choice I have to make the where clause.
  That is why, for the execution of the query, I put ' > ' in this place.
  
  If the original query will look like this (for reference):
  
  Select cr.customer_name. ' - ' || CR.customer_number as cust_name,
  CR. Salary salary
  of customer_details cr
  where (case when variable = ' > ' then ' cr.salary > 5000')
  When the variable = ' < ' then ' cr.salary < 5000'
  When the variable = '=' and then 'cr.salary = 5000'
  Another null
  (end);
  
  
  so, in a real case, if the user selects ' > ' then the filter will be ' where cr.salary > 5000.
  If the user selects ' < ' then the filter will be ' where cr.salary < 5000.
  If the user selects '=', then the filter will be 'where cr.salary = 5000 '.
  
  but I get the error "ORA 00920:invalid relational operator.
  
  Help, please... Thanks in advance...

  Hello

• Where clause in the "default_where" of get_block_property is not cancelled...

  Hello

  I developed a form with two blocks.

  The first - block of non - database contains the criteria.

  Database of the other - block-displays the records according to the inserted.

  Also, there is a button that executes the query criteria.

  The code of the BUTTON WHEN PRESSED is as follows:

  declare

  v_where varchar2 (3000);

  Start

  v_where: = null;

  go_block ('EKKREMOTHTES_AIT_TSG');

  clear_block (no_validate);

  v_where: = get_block_property ('EKKREMOTHTES_AIT_TSG', default_where);

  If: blk_criteria.site_id is not null then

  v_where: = v_where |' and site_id = "'|: blk_criteria.site_id | ''';

  end if;

  If: blk_criteria.yphr_klimakio is not null then

  v_where: = v_where |' and yphr_klimakio = "'|: blk_criteria.yphr_klimakio | ''';

  end if;

  If: blk_criteria.send_date_from is not null and: blk_criteria.send_date_to is not null then

  v_where: = v_where |' and send_date between to_date('''|| to_char(:blk_criteria.send_date_from,'dd/mm/yyyy')||''',''dd/mm/yyyy'') and

  to_date('''|| to_char(:blk_criteria.send_date_to,'dd/mm/yyyy') | " (', "dd/mm/yyyy)";

  end if;

  If: blk_criteria.eq_group1 is not null then

  v_where: = v_where |' and eq_group1 = "' | : blk_criteria.eq_group1 | " ' ;

  end if;

  If: blk_criteria.eq_type1 is not null then

  v_where: = v_where |' and eq_type1 = "' | : blk_criteria.eq_type1 | " ' ;

  end if;

  If: blk_criteria.eq_group2 is not null then

  v_where: = v_where |' and eq_group2 = "' | : blk_criteria.eq_group2 | " ' ;

  end if;

  If: blk_criteria.eq_type2 is not null then

  v_where: = v_where |' and eq_type2 = "' | : blk_criteria.eq_type2 | " ' ;

  end if;

  blk_def_where ('EKKREMOTHTES_AIT_TSG', v_where);                                    / * a form routine that makes the set_block_property(<block>,default_where) * /.

  do_key ('execute_query');

  end;

  The above code works when the user inserts the criteria for the first time. Later when the user deletes certain criteria - clear criteria in the block of criteria-

  and he pushed the button of the query results are exactly the same...

  After have debugged the problem, clause v_where is not nullied (do not get the value zero) in order to get the new criteria.

  Can you identify the error?

  Note: I use Oracle Forms 10 g Db 11 g v.2

  Thank you very much

  SIM

  SIM,

  The procedure "blk_def_where" sets the block where clause by using the DEFAULT_WHERE or the ONETIME_WHERE constanct?  Gets it to the user that the same results as the DEFAULT_WHERE sets the property WHERE permanently so the second time through, the 'v_where' is NOT null.  Check your BLK_DEF_WHERE procedure and if it does not use the ONETIME_WHERE constanct, change isn't.  The alternative would be to put DEFAULT_WHERE = NULL after the call to the built-in EXECUTE_QUERY.

• By using a WHERE clause in the tree APEX

  Hi all -

  I have a hierarchical SQL query that I display as a tree of the APEX.

  Here is my sample application:

  https://Apex.Oracle.com/pls/Apex/f?p=32581:29

  Login: guest

  PW: app_1000

  workspace: leppard

  I try to add a WHERE clause so that only nodes with the lowest-level children are displayed, i.e. something like "WHERE connect_by_isleaf = 0 OR level = 5'"

  The tree of query with where clause works very well in the SQL command window, but when I add the WHERE clause to my tree apex page no longer displays anything. Is this a problem with APEX or y at - it another way to filter my results?

  Thanks in advance for your suggestions,

  John

  Connect occurs in the first place, the where the provision is applied to these results, effectively cutting in the hierarchical structure. Since the apex has build a hierarchical structure of the query, it relies on the virtual level, which is butchered by applying the where clause. It's a miracle that you're not even receive errors because I expect almost an incorrect json array was built. With no top-level from and only level 5 or end nodes, there is no structure to present: the two apex cannot set a correct representation and not jstree neither. In your request, you will see your "root nodes", but it is not representable.

  I don't know why you want to present it in a tree? Levels both connect_by_is_leaf = 5 will give you everything just a list of nodes without any hierarchical structure.

  The best thing to do is to use a subquery to limit first your dataset and then use it for the basic tree query, this way you violate one of these vital columns.

  For example if you want only nodes and their immediate parent, you can opt for something like this (fast on some testdata model):

  with dataset as (
  select node_id, parent_id
     from treedata
    where connect_by_isleaf = 0
  connect by prior node_id = parent_id
    start with parent_id = 0
  ),
  dataset2 as (
  select node_id, parent_id
    from dataset
  union all
  select node_id, null parent_id
    from treedata
  where node_id in (select parent_id from dataset)
  )
  select level, node_id
     from dataset2
  connect by prior node_id = parent_id
    start with parent_id is null

• ViewObject where Clause SET based on logged in user roles

  Hello Experts

  I have a view object based on a custom query to get distinct values from a table. My requirement is to display the results as a listview. The listview is is filled without any problem. But I need to add a where clause clause the object view based on the user roles.

  I have a method that generates the where clause and returns one string something like "COUNTRIES ('USA', 'UK').

  I created a class of the view object Impl and put WhereClause as below: but where clause is not applied when I run the page. I see everywhere instead of just USA & UK.

  Can you let me know at what time should I set the where the clause?

  SerializableAttribute public class CountriesVOImpl extends ViewObjectImpl {}

  /**

  * This is the default constructor (do not remove).

  */

  public CountriesVOImpl () {}

  this.setWhereClause (getCountries ());

  }

  public String getCountries() {}

  return '('USA', 'UK') COUNTRIES. "

  }

  }

  In class ViewImpl try to replace "executeQueryForCollection" and setWhereClause in this function as:

      protected void executeQueryForCollection(Object object, Object[] object2, int i)
      {
          setWhereClause("COUNTRY in ('USA','UK')");
          super.executeQueryForCollection(object, object2, i);
      }
  

• Cannot run a «BUSINESS...» WHEN ' with a date in a WHERE CLAUSE condition

  Hello

  I need to check for a condition and date according to the date, he would check a set of host names or the other game... so I thought I could write something like this in the WHERE clause:

  AND HOST_NAME IN

  (

  CASE

  WHEN TO_DATE (: StopDate, 'MON-DD-YYYY') > = TO_DATE ('22 - DEC - 2015 "," DD-MON-YYYY ') THEN

  ('SERVERNAMEA', 'SERVERNAMEB', 'SERVERNAMEC') ON THE OTHER

  ("SERVERNAME1", "NAMESERVER2", "SERVERNAME3")

  END

  )

  I get the following:

  ORA-00907: lack of right parenthesis

  00907 00000 - "lack the right parenthesis.

  But there is no missing parentheses!

  If I take the case... when... end, and run the host_name in ('SERVERNAMEA', 'SERVERNAMEB', 'SERVERNAMEC') (separately, they run fine)...

  I also tried:

  AND

  (

  CASE

  WHEN TO_DATE (: StopDate, 'MON-DD-YYYY') > = TO_DATE ('22 - DEC - 2015 "," DD-MON-YYYY ') THEN

  HOST_NAME IN ('SERVERNAMEA', 'SERVERNAMEB', 'SERVERNAMEC') ELSE

  HOST_NAME IN ('SERVERNAME1","NAMESERVER2","SERVERNAME3")

  END

  )

  the error I get is:

  ORA-00905: lack of keyword

  00905 00000 - 'lack the key word'

  What keyword miss me?

  It was a typo when transferred to the Oracle forum... the version of Oracle is: PL/SQL version 10.2.0.3.0 (10 G)

  I also used IF the statement and that has not worked (in error "missing parenthesis") which I'm sure is a matter of "syntax"... I did not know that the CASE statement returns the value single only, so it's probably the problem.  Is it possible to re - write this?

  ...

  IF only works in PL/SQL.  It does not in SQL, even if that SQL is embedded in PL/SQL.

  There are many ways to re - write the condition.  And here's one:

  AND ((host_name IN ('SERVERNAMEA', 'SERVERNAMEB', 'SERVERNAMEC')

  AND TO_DATE (: StopDate, "MON-DD-YYYY") > = TO_DATE ('22-DEC-2015', "MON-DD-YYYY")

  OR (host_name IN ('servername1","Nameserver2","SERVERNAME3")

  AND TO_DATE (: StopDate, "MON-DD-YYYY")<  to_date="" ('dec-22-2015', ="">

  )

  )

  If: StopDate can be NULL, it must be a bit more complicated.

  You can also use nested, such as CASE expressions

  AND THE CASE

  WHEN TO_DATE (: StopDate, "MON-DD-YYYY") > = TO_DATE ('22-DEC-2015', "MON-DD-YYYY")

  WHILE CASE

  WHEN host_name IN ('SERVERNAMEA', 'SERVERNAMEB', 'SERVERNAMEC')

  AND THEN 'OK '.

  END

  OTHER CASES

  WHEN host_name IN ('servername1","Nameserver2","SERVERNAME3")

  AND THEN 'OK '.

  END

  END = 'OK '.

  I wonder if this in your application is the best way, however.  If SERVERNAMEA was put into service on December 22, maybe that that fact should be recorded in a table.  If you have a table with 1 row per server, you can consider adding 2 columns DATE to show when the server was first and last used.  Then, rather than use a WHERE clause to test servers appropriate, you could do an inner join.

• 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

  This will always be value true - similar to WHERE 1 = 1.

  You typed it wrong or is the same as the variable column name? If they are the same test rename one of them.

• 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,

  Hello

  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.

• [ADF, JDev12.1.3] How to set a variable to bind a VO (where clause) in a managed bean?

  Hallo,

  I have a request based on VO.

  The query contains a where clause clause and a bindi variable.

  In a managed bean I would like to access the iterator of VO setting the value of the bind variable and read the result.

  I found this code it is good start, but I do not know how to set the variable binding.

  BindingContext bctx = BindingContext.getCurrent();
  BindingContainer bindings = bctx.getCurrentBindingsEntry();
  DCIteratorBinding iter = (DCIteratorBinding ) bindings.get("MyVO1Iterator");
  iter.execute();
  
  
  

  You kindly help me?

  Also, I would like to know if it is generally advisable to use VO directly in controlled beans or whether it would be best to create in the AppModuleImpl methods that do this and return the result.

  In my case for example of the VO will return max 1 plug so I'm in doubt, if the creation of a method in the AM that returns a custom class, which attributes contain values of the line of VO.

  Sorry if these questions may seem artificial, but I am a beginner, I have many doubts and so I would be happy to receive some tips regarding best practices.

  Thank you

  Federico

  You can use:

  iter.getViewObject().setNamedWhereClauseParam("yourBindVar", value);
  

  Note that this approach is used if you have bind variable in the where clause.

  To set variables bind to ViewCriteria, you must use VarableValueManager.

  This post may be useful for you: binary: how to set the Bind variable values at run time?

  Also, I would like to know if it is generally advisable to use VO directly in controlled beans or whether it would be best to create in the AppModuleImpl methods that do this and return the result.

  You must set "use VO directly.

  For example, from the point of architecture, is probably best to use the method in the model project which will set the bind variable and execute the query.

  Or you can use the ExecuteWithParams operation in your the view layer.

  In my case for example of the VO will return max 1 plug so I'm in doubt, if the creation of a method in the AM that returns a custom class, which attributes contain values of the line of VO.

  Not to complicate your life

  All VO lines are represented as ViewRowImpl class if you already have "custom class".

  Finally, you can generate your own ViewRowImpl class if it is necessary for this.
