Question of WHERE Clause.

• 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 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.

• WHERE clause order ox performance question

  I do not understand order of execution of a WHERE clause, the use of a complex database
  
  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
       )

• 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".

  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.

• Small design on the points of view and a Where Clause Board...

  Hi all...  I just want to check Im doing things right, and he is not a better way to do this...

  Running APEX 4.2.5 and XE 11.2

  Ive built my application around a community of users who have access to certain groups of data...  Ive designed so that there are views and then transparent filter the data of a given user. for example, the view below seamlessly that users can see the filters depending on which application they use, they can see more specifically, what are the features and finally, what group they are actually in.

  Create view ENTITIES like)

  Select * from t_entities t

  where exists (select 1

  of application_groups ag

  where ag.object_name = 'ENTITIES '.

  and ag.object_id = t.entity_id

  and ag.group_name = 'CASH FLOW')

  and exists (select 1 from entity_users EU

  where eu.username = nvl (v ('APP_USER'), USER) / * APEX APPLICATION USER * /.

  and eu.entity_id = t.entity_id)

  and it exists (select 1 from entity_group_members for example

  where eg.entity_group = v('G_ENTITY_GRP_ID') / * ENTITY_GROUP * /.

  and eg.entity_id = t.entity_id)

  )

  The overall costs when I run the explain command is very low (23 or almost), so I think that its an effective way of filtering... However, out of 300 entities or greater, the vast majority of users (75%) can see 75% of data...  Also, I need to create another view to filter another set of data with 2000 records. one with the view in place, 95% of the staff will see 95% of the data and only 10% of the staff see the other 10%...

  I note that its faster when a member of a group brings back only a tiny part of the data compared to the other way around... This is why Im asking before implementing another view of the same type.

  So, on my question. Is there a better way to do this, or the query should be on there head with a WHERE clause does NOT EXIST (xxxxx! = yyyyy)) or soemthing else ther is quite that Ive missed...

  The only other comment is that Im using the upper table "APPLICATION_GROUPS" for more than one type of object (i.e. entities and entity accounts banking..) y at - it no merit in separaitng the two into two tables?

  Thank you very much

  Richard

  Hi Richard,

  Miss me a lot of information but:

  I think that your design could be allowed. It seems a little too mat, maybe, but I think this could work.

  It is important to have the good indexing and use compression of index:

  On application_groups (object_name, the GroupName, groupname) compresses

  IT compresses to entity_users (username, entity_id)

  On the entity_group_members (entity_group, entity_id) compress

  I think v as v ('G_ENTITY_GRP_ID') is a user-defined function? If so, if possible, set the deterministic and uses result_cache.

  Consider partitioning application_groups type (= object_name?)

• [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.

• Order columns (which make up the primary key constraint) matter in where clause of DML query for use of indexing mechanism to operate.

  Version of DB: database Oracle 11 g Enterprise Edition Release 11.2.0.3.0 - 64 bit Production

  
  I have a table my_table as below:

  Primary_key here's a composite key that contains columns 1 (my_code) and 2 (my_id).
  Is there that a difference in the way below queries is executed in terms of performance (use of indexing in the extraction).

  (a) select * from my_table where my_code = '123' and my_id = "456";
  (b) select * from my_table where my_id = '456' and my_code = '123';

  
  The understanding I have the order of the column in the where clause should be identical to the sequence in
  What primary key draws for indexing to be used by oracle in oracle other DML queries ignores indexing
  However when I used explain plain both show the same query cost with single scan with index rowid.

  Your question is answered in the Performance Tuning Guide

  Using indexes and clusters

  14.1.4 choosing composite indexes

  A composite index contains several key columns. Composite indexes can provide additional benefits compared to the index to single column:

  • Improved selectivity

    Sometimes the two or more columns or expressions, each with a low selectivity can be combined to form a composite with a high selectivity.

  • Reduced IO

    If all columns selected by a query are a composite index, then Oracle may return these values in the index without access to the table.

  A SQL statement can use a path on a composite index if the statement contains constructions that use a main part of the index.

  Note:

  This is no longer the case with the skip index scans. See "Index Skip Scans".

  A main part of an index is a set of one or more columns that have been specified first and consecutively in the list of columns in the CREATE INDEX statement that created the index.

• 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.

• 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!

  Thank you for the reply.

  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.

• alias in where clause

  Hello
  
  It is a question of OCA certification.
  
  1. SQL > SELECT prod_name, prod_list_price, prod_list_price-(prod_list_price*.25) "DISCOUNTED_PRICE".
  PRODUCTS
  WHERE the discounted_price < 10;
  
  The query generates an error.
  What is the reason for generating fault?
  A. the parentheses should be added to frame the entire expression
  B. the quotes should be removed from the column alias
  C. column aliases must be replaced by the expression in the WHERE clause
  D. column aliases must be capitalized and closed double quotes in the WHERE clause
  
  Answer: D
  
  
  My question is how we can use aliases ("DISCOUNTED_PRICE") in where clause (WHERE "DISCOUNTED_PRICE" < 10)?
  
  Please specify.

  Hello

  C. response (and I think, you not write review at this time)

  You cannot use alias name in the WHERE clause.

  And if you want to continue to use DISCOUNTED_PRICE in the WHERE clause, you can use view inline.

  SELECT *
  FROM (SELECT prod_name,prod_list_price,prod_list_price-(prod_list_price*.25) "DISCOUNTED_PRICE"
  FROM products
  )

  SELECT POVs.vendor_site_code site, pov.vendor_id
  OF po_vendors pov, povs po_vendor_sites_all
  WHERE pov.vendor_id = povs.vendor_id
  AND TRUNC (povs.inactive_date) IS NULL
  
  
  PO NUMBER LOV QUERY VO
  
  
  SELECT DISTINCT ai.invoice_num, ai.vendor_id, ai.invoice_date, poh.segment1
  AI ap_invoices_all,.
  help ap_invoice_distributions_all,
  po_headers_all poh,
  po_distributions_all pda,
  Al ap_lookup_codes
  WHERE aid.po_distribution_id = pda.po_distribution_id
  AND ai.invoice_id = aid.invoice_id
  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");
  if(vo!=null)
  {
  vo.clearCache ();
  VO. Reset();
  System.out.println ("inside IN. VO:" + vendor_id1);
  vo.setWhereClause (null);
  vo.setWhereClause ("vendor_id =: 1");
  vo.setWhereClauseParams (null);
  vo.setWhereClauseParam(0,vendor_id1);
  vo.setOrderByClause ("invoice_date DESC");
  String INVQRY = vo.getQuery ();
  System.out.println ("INVQRY:" + INVQRY);
  vo.executeQuery ();
  VO. First();
  System.out.println ("after the query appear" + vo.getRowCount ());
  }
  
  OAViewObjectImpl sitevo1 = (OAViewObjectImpl) am.findViewObject ("SUPPLIER_SITE_VO1");
  if(sitevo1!=null)
  {
  sitevo1.clearcache ();
  sitevo1. Reset();
  System.out.println ("Interior site:" + vendor_id1);
  sitevo1.setWhereClause (null);
  sitevo1.setWhereClause ("vendor_id =: 1");
  sitevo1.setWhereClauseParams (null);
  sitevo1.setWhereClauseParam(0,vendor_id1);
  String SITEQRY = sitevo1.getQuery ();
  System.out.println ("SITEQRY:" + SITEQRY);
  sitevo1. ExecuteQuery();
  sitevo1. First();
  System.out.println ("after the query appear" + sitevo1.getRowCount ());
  }
  
  
  
  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
