• any case when and the sql clause

  Hello:
  What follows is my sql clause:
  SELECT T.*, b.name
  OF dbtest1 t
  LEFT OUTER JOIN dbtest b ON t.NO = b.empno
  WHERE t.ChineseName like '% "| : ChineseName | ' %' AND b.name like "%" | : name | » %'
  ORDER BY t.ChineseName
  
  The main problem is that I want to check the b.name if it is null, it can be passed as function NVL, so I try using case when, but it does not work.
  When there are the b.name in where clause, the columns of result will not include data without b.name (or implies the b.name is NULL); And that
  the result data are not entirely accurate.
  is it possible to use the case when it is implemented in the following code snippet:
  
  -case when b.name is not NULL then b.name like "%" | : name | » %'
  Else b.name = NULL (b.name = b.name does not seem to work on the analysis of data zero)
  end
  
  Thank you very much.

• These SQL clauses are equivalent?

  Hi, previously I was working in a SQL statement that returns potentially 1 million rows. The 'order by' clause contributes significantly the cost when I checked its plan to explain.
  

  select ...
  from ...
  order by field1, field2, field3;

  Then I found another way to make the order of who has much lower costs to explain the plan.

  select ...
  , dense_rank() over (order by field1, field2, field3) overall_order 
  from ...
  order by overall_order;

  Both queries took a long time to run if I didn't not wait until this one is over. The question I have is the above two methods will return the same result in the same order? I know dense_rank() returns the same number of ranking if two values are the same, but do not know what 'order by' will do in the same situation.
  
  I found that when the result set is small (say, a few hundred lines), the analytic function actually result in a higher cost to explain plan. Please let know us if it is OK to use the second method to achieve the effect of "order by" for the large result set.
  
  If you have better alternatives, please suggest as well. Thank you.

  Hello

  Two of these methods do the same thing.

  Both are for an indefinite period as to what happens when two or more rows have the same values for the three variables.
  Say the lines A, B and C all have exactly the same values for field1, field2, and field3.
  Say, you are running the version with ' ORDER BY Field1, Field2, formees3 ' and the output, in order, is A, B, C.
  If you run one version, then there is no guarantee that you will again get the same order (A, B, C). You can get the same order, or you might not.

  I'd be surprised if "ORDER BY overall_order" was faster than ' ORDER BY Field1, firld2, field3.

• The USE of dynamic SQL clause

  Hi Valerie,

  To add to what Peter, said

  "Binding" values in a query is done for a specific purpose, and this purpose is so that the optimizer can use the same query as the previous execution plan runs the query, which prevent it from having to analyze the hard the query each time. A query execution plan is based on the tables and columns are presented in the query, but with respect to the actual "values" of these columns, they are unlikely to change the execution plan. So, to keep the same execution plan, the query must seem identical (in terms of a query string) like the previous series, so if you want the same query, but just with different values, they can be replaced with bind variables (these things have a ': ' character) and then the values passed in the query, when it is run.

  Now, if Oracle were to allow you to link in the names of objects, such as tables, this means that it could not use the previous execution plans, because he doesn't know until run time what tables will be consulted. Therefore, it would be useless link in the values of the query and it would be just as quick to implement your query string by concatenating all the values inside rather than link them. Considering that a query is parsed first and then the values in it, then it cannot be analyzed if the tables are not known everything first. (Take a look at how queries are formed and variables when you use the DBMS_SQL package).

  So the key thing to remember is that, when it comes to bind variables, you can bind only the 'values', not 'objects '.

• JOIN the SQL clause

  Hello
  
  I have a small question:
  
  INNER JOIN can be written with just the keyword JOIN?
  
  For example,.
  
  INNER JOIN table_b b ON a.col = b.col
  
  OR
  
  JOIN table_b b ON a.col = b.col
  
  Thank you

  Yes it is JOIN table_b b WE a.col = b.col or INNER JOIN table_b b ON a.col = b.col

• Setting of outsourcing work is not for a SQL Where clause

  Im trying to outsource the WHERE SQL clause of a snapshot data (connecting to Siebel DB) and specify where clause in the run profile that does not work.

  Snapshot of research: Select the name of siebel.s_org_ext

  Parameter of outsourcing: where_clause_sql

  Run the content of the profile:
  

  phase. Phase1.snapshot.clt.where_clause_sql = name = "ABC0009".

  #phase. Phase1.snapshot.clt.snapshot_sql = select name from siebel.s_org_ext where name = 'ABC0009 '.

  The above parameter retrieves all the records in the table. Below the profile execution retrieves just this record that seems to work fine.

  
  

  Run the content of the profile:
  

  phase. Phase1.snapshot.clt.snapshot_sql = select name from siebel.s_org_ext where name = 'ABC0009 '.

  
  

  I want to outsource only where clause as there are many SQL and they are huge to maintain in the run profile.

  I have attached a doco with screenshots that will help to understand more.

  Hello

  You must BE

  -Choose "Select table or view" in the table of the snapshot Wizard selection page

  &

  -Use outsourced where clause

  OR

  -Choose "SQL" in the snapshot table selection wizard page.

  &

  -Outsourced use SQL snapshot

  You can't mix and match options.

• How to close the popup window after executing PL/SQL?

  Hello

  To see a junior question: we use APEX 5.0.2

  On a page of the modal dialog (of an interactive report), for the button create, I created a dynamic action that runs the specific code from PL/SQL to insert a new item.  Then behind the insert clause, I have the code to close the pop-up window, so that it executes successfully the insert clause without closing the window.  Please let me know what I can do.  Thank you.

  HTP.p ("< script > '");

  HTP.p ('window.opener.Location.Reload ();) Window.Close ();') ;

  HTP.p ("< /script >" ");

  Kind regards

  Jian

  OK, thanks for all your help and ideas. Finally, I gave up running JavaScript, instead, I created another dynamic action that closes the dialog box with a later sequence (for example, it runs after the PL/SQL code).  Now, it closes the windows properly after running pl/sql clause.  Although I still wonder how to run JavaScript because it doesn't do anything, even when I create a process to run javascript directly.

• 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.

• There is no possibility of ambiguity in the SELECT clause because any identifier in the SELECT clause must be a database column name

  Hello

  Doc Oracle says the following on the identifiers in the SELECT in PL/SQL clause: there is no possibility of ambiguity in the SELECT clause because any identifier in the SELECT clause must be a database column name.

  If we assume that only valid column identifier are allowed in the SELECT clause.

  But I tried the following:

  DECLARE
  toto NUMBER := 10;
  tata NUMBER := 0;
  BEGIN
  SELECT toto INTO tata FROM employees WHERE employee_id = 101;
  DBMS_OUTPUT.PUT_LINE(tata);
  END;
  /
  

  And there is no error telling me that toto is not a column in the employees table and the result is the same as: toto: = aunt;

  Won't the doc or did I just miss something?

  You're right that toto is an identifier, but this isn't a column name.  (Of a subquery) column alias are not database of the names of columns either, nor are the names of the user-defined function.

  Also, there is a possibility for ambiguity even if all the names are the database column names.

  Won't the doc or did I just miss something?

  I can't say until I see the doc you're talking about.

  Oracle documentation is sometimes misleading and sometimes just plain wrong.  For each mistake outright example that I saw in the docs of Oracle, there might be 20 cases where the meaning is unclear or misleading and maybe 200 where I just read it wrong.

• Conditional SQL

  Oracle 11g.

  In General to know where sql clause, such as: where account_id = p_acct_id means that for a specific account_id.  Now, I want to build provided that is a flag setting s = p_flag ' use

  where ID_compte = p_acct_id, otherwise account_id will be ignored.

  For example:

  If using mutiple instruction is like this

  If (p_flag = the of ') then

  Select in...

  where account_id = p_acct_id and p_oth_id = other_id

  on the other

  Select in...

  where other_id = p_oth_id

  end if;

  But, how can I write it in a where clause?

  
  

  
  

  Thank you

  Hello

  Here's another way:

  WHERE (account_id = p_acct_id

  OR NVL (p_flag, 'OK'). = s "

  )

  AND other_id = p_oth_id

  This will work even if p_flag and/or account_id is NULL.

  CASE expressions are really practical in the SELECT and ORDER BY clauses, because they allow you to do an if-then-else logic in these places.

  WHEN the clauses have their own way of doing if-then-else logic, so the CASE expressions are not necessary much in WHERE clauses.

• Decimal separator in the SELECT Clause

  Hello
  
  I have the following parameters of decimal number:
  
  SQL > select value
  2 from v$ nls_parameters
  3 where parameter = "NLS_NUMERIC_CHARACTERS;
  
  VALUE
  ----------------------------------------------------------------
  ,.
  
  If I show a decimal number, I get a comma as decimal separator
  SQL > select 10/100 double;
  
  10/100
  ----------
  1
  
  But if I use a decimal separator in the SELECT clause, I get:
  
  SQL > select 100 * 1.1 double;
  
  100 * 1 1
  ---------- ----------
  1 100
  
  It does not work. But the use of a period as the decimal separator works:
  
  SQL > select 1.1 * 100 double;
  
  1.1 * 100
  ----------
  110
  
  Maybe it's something that I never had to deal with before, but I thought that the number format applied to results of sql, as well as the numbers you have used sql clauses.

  Hi, Nestor,

  user594312 wrote:
  ... I thought that the number format applied to results of sql, as well as the numbers you have used sql clauses.

  No.; it applies to the results and it can affect implicit conversions, but it does not apply to the SQL code.
  The period (or dot, '.') is the decimal separator in literals always digital. There is no way to change this.

  Think how confusing it would be if it applied to the SQL code. For example:

  WHERE   num_col  IN (1,2)
  

  We compare num_col values 1 or 2? He comes in, what happens if we wanted to do the opposite?

  If you really want to use the comma as the decimal separator, you may have to use strings, not numbers, and it could be much less effective.
  For example:

  SELECT  100 * TO_NUMBER ('1,1')    -- This assumes your NLS settings are correct
  FROM    dual;
  

  Of course, the effectiveness will not be a problem when you select 1 row of double.

• Pivot control, can the IN clause be dynamic instead of hard-coded values?

  I want to have a number of statements that use the PIVOT command can run dynamically without having to hardcode the values I want to be selected within the 'IN' of sql clause. Here's a simple example.
  
  REGION_ID COLUMNS SALES_MONTH NUM_SALES
  
  1 02/01/2010 12
  2010-01-03 1, 11
  1 04/01/2010 10
  02/01/2010 2, 22
  03/01/2010 2, 21
  2 04/01/2010 20
  
  The PIVOT command, I used is the following:
  
  Select * from
  (select * from sales)
  PIVOT
  (
  Sum (num_sales)
  for columns sales_month in (February 1, 2010", March 1, 2010", 1 April 2010 "))
  
  This works very well for now, but as new months are created, I don't want to have to redo all my sql monthly statements. Any suggestions on how I can do this?

  No, unless you use swivel XML:

  select  *
    from  (
           select  job,
                   deptno,
                   sal
             from  emp
          ) pivot xml(sum(sal) for job in (select distinct job from emp))

• SQL update does not

  Hello

  I'm trying to update my database with the following code, but although the code runs without a doubt because he can't seem to echo on the line before the update, the database is not updated.

  If ($totalRows_rsportsale > '0') {}
  $_POST ['dpaid'] = 1;
  $_POST ['listedby'] = $row_rsportid ["listedid"];
  echo ' dpaid is: '. $_POST ['dpaid']. ' < br / > ';
  echo ' listedby is: '. $_POST ['listedby"]. ' < br / > ';
  $updateSQL = sprintf ("UPDATE detailstable SET dpaid = WHERE listedby %s is %s",
  GetSQLValueString ($_POST ['listedby'], "int").
  GetSQLValueString ($_POST ['dpaid'], "int"));

  @mysql_select_db ($database_connUpdate, $connUpdate);
  $Result1 = mysql_query ($updateSQL, $connUpdate) or die (mysql_error ());
  }

  I want to update the database values actually echo right before the update script, so the values are correct for dpaid and listedby, I entered the ILO code was updated in the SQL myphp admin and that updates the database. The connection to the database connUpdate is correct. The two fields are of type "int" in the database and are not primary or unique keys. Any suggestions as to why this update does not work would be very appreciated.

  Thank you in advance.

  No, I don't mean the order of SQL clauses, I mean the order of the two settings that you use.

  $updateSQL = sprintf ("UPDATE detailstable SET dpaid = WHERE listedby %s is %s",
  GetSQLValueString ($_POST ['listedby'], "int").
  GetSQLValueString ($_POST ['dpaid'], "int"));

  As I said, I don't know PHP or sprintf command, but I guess that it replaces the parameters (%s) in the order that they appear. Your (listedby and dpaid) SQL statement parameters are in reverse order. Try to change them.

  $updateSQL = sprintf ("UPDATE detailstable SET dpaid = WHERE listedby %s is %s",
  GetSQLValueString ($_POST ['dpaid'], "int")).

  GetSQLValueString ($_POST ['listedby'], "int");

  It works very well on our test database (10.2.0.1.0), but when I try to run it on our production database (10.2.0.4.0), it gives the following error:
  ORA-00904: "KON". "" KONTAKT_IK ": invalid identifier
  
  The nested select works fine when I run it separately (without where clause of course, because then it does not really anywhere point) on two databases, but for some reason, the full update only fails on the production system. Any ideas on what could cause this?
  
  Kind regards

  You can run it without selecting it nesting.

  Like this

  update f_kontakti kon
  set ikaluokka=
   (
    select ikaluokka_gen(1,ai2.pvm,ai.pvm) as ikal
    from f_kontakti k
    join d_asiakas a on (k.asiakas_ik=a.asiakas_ik)
    join d_aika ai on (a.synt_aika_ik=ai.aika_ik)
    join d_aika ai2 on (k.aika_ik=ai2.aika_ik)
    where k.kontakt_ik=kon.kontakt_ik
  );
  

  or even shorter

  update f_kontakti kon
  set ikaluokka=
   (
    select ikaluokka_gen(1,ai2.pvm,ai.pvm) as ikal

• First value in ORDER MIN different BY

  Hello

  According to the docu NLS_SORT must determine the order of sort ORDER BY and MIN/MAX

  Oracle Database 11 g Enterprise Edition Release 11.2.0.2.0 - 64 bit Production

  SELECT *. OF nls_session_parameters Setting WHERE = "NLS_SORT. OR a parameter = "NLS_COMP; VALUE OF THE PARAMETER ----------- ------- NLS_SORT GERMAN BINARY NLS_COMP

  I therefore expect that I get the same first / min and last/max values of the following

  Oracle Database 11 g Enterprise Edition Release 11.2.0.2.0 - 64 bit Production

  WITH testdata as) SELECT 'A' double UNION ALL c SELECT 'B' c IN double UNION ALL SELECT '0' c TO double UNION ALL SELECT '1' c double UNION ALL SELECT FROM c '2' double ) SELECT MAX (c) MIN (c) OF testdata. MAX (C) MIN (C) ------ ------ B 0 WITH testdata as) SELECT 'A' double UNION ALL c SELECT 'B' c IN double UNION ALL SELECT '0' c TO double UNION ALL SELECT '1' c double UNION ALL SELECT FROM c '2' double ) C SELECT ASCII (c) OF testdata ORDER BY c; C ASCII (C) - ---------- A 65 B 66 0 48 1 49 2 50

  So I read on the sort

  Oracle Database 11 g Enterprise Edition Release 11.2.0.2.0 - 64 bit Production

  ALTER SESSION SET NLS_SORT = "BINARY"; C ASCII (C) - ---------- 0 48 1 49 2 50 A 65

  
  B 66

  Now, I get the expected results, but I can't always explain why a linguistic sort order letters before numbers and why it's different to ORDER BY and MAX/MIN.

  Concerning

  Marcus

  According to the docu NLS_SORT must determine the order of sort ORDER BY and MIN/MAX

  OK, but you overlooked that part:

  Accurate operators and the query clauses that obey to the NLS_SORT parameter depends on the value of the NLS_COMP parameter. If a clause or an operator does not comply to the NLS_SORT value, as determined by NLS_COMP , the collation used is BINARY .

  In your example, MIN and MAX always use BINARY collation, unless NLS_SORT is set to a specific language and NLS_COMP is LINGUISTICS.

  On the contrary, ORDER BY, always obeys the NLS_SORT setting regardless of the NLS_COMP parameter.

  This summarizes what operator and SQL clause obeys what parameter:

  Linguistic sorting and string search
