  You mean > = instead of >, to register the join_dates that are exactly 12:00:00 AM on March 23.  Keep< at="" the="" end;="" you="" don't="" want="" anything="" from="" march="" 24,="" and="" you="" don't="" want="" between="" for="" the="" same="">

  What you posted is the fastest way.  Use DATE instead of TO_DATE literals, it is a bit shorter and just as fast.

  SELECT *.

  WCP

  WHERE join_date > = DATE '' 2005-03-23

  AND join_date<  date="">

  ;

  May be the shortest path (which will be slower):

  SELECT *.

  WCP

  WHERE TRUNC (join_date) = DATE '' 2005-03-23

  ;

  It's slower because we need to call a function for each row in the table, and (potentially much larger) this means that you cannot use an index on join_date.

• What is the right answer, is that this issue is sql?

  Hello.. Please I need a correct answer to this question...

  See the exhibition and examine the structure of the PRODUCTS table.

  Using the PRODUCTS table, you publish the following query to generate names, current list prices, and

  price list for all these products whose list price falls below $10 after that a discount of 25% reduced

  on this subject.

  SQL > SELECT prod_name, prod_list_price,.

  prod_list_price - (prod_list_price *. 25) "DISCOUNTED_PRICE".

  PRODUCTS

  WHERE discounted_price < 10;

  The query generates an error.

  What is the reason of the error?

  Has the parentheses should be added to frame the entire expression.

  B - double quotes should be removed from the column alias.

  Column alias C - replace it with the expression in the WHERE clause.

  Alias column D - The should be capitalized and closed with the double quotes in the WHERE clause.

  Took me 5 seconds to see that in Google: alias in where clause that exactly answers your question.

• Issue of SQL Plan Management

  Hello
  
  I have a question concerning the presence of 'Accepted' indicator (values or NOT) that is displayed by the function dbms_xplan.display_sql_plan_baseline.
  
  It is my understanding of the documentation of Oracle SQL plan does not become part of a plan SQL database until it is accepted by the process of evolution or manual loading in the base line. How is it possible to have a plan to be part of a reference that is not accepted? If the dbms_xplan.display_sql_plan_baseline function is used to display more than plans that are in a reference database and that are only in the story?
  
  
  Thanks for your thoughts on this.
  
  Richard
  
  PS. I use Oracle 11.1.0.7

  Welcome to the forum!

  View code that you use to call the function and the result you get.

  Depending on how you call the function, and what plans are available, you will get different results. For example
  >
  plan_name
  Name of plan. It identifies a specific plan. Value default NULL means that all the plans associated with identified SQL statement are explained and displayed
  >
  You specify this setting? If this isn't the case, then all THE plans could include plans that have not been accepted.

  Section 15.5 display SQL Plan baseline in the Performance Tuning Guide contains an example of this and displays two plans: an accepted and the other not.
  http://docs.Oracle.com/CD/E11882_01/server.112/e16638/optplanmgmt.htm

  It's really the history display that includes all plans.

• Issue of SQL Hieraerchical

  Oracle Enterprise Version 11.2.0,.3

  I need to write a hierarchical query to give me registration with the version of henriq # if the record is a child of a parent. If the folder has no children so I need the parent to save himself.

  {code}

  Employee:

  ID	ParentId	Version #
  1		1
  2		1
  3	2	2
  4	3	3
  5	4	4
  6		1
  7	5	5
  8		1

  For example:

  so I need to show the sheet 1 1 recordID did no parentid

  RecordID 8 has no parentid so I need to see the card 8

  RecordID 2 has 4 levels of children, I need to get the record with max version 5 i.e Recordid 7

  2            1

  3-2-2

  4-3-3

  5-4-4

  7-5-5

  Expected result

  ID Parentid Version

  1            1

  7-5-5

  8            1

  Hello

  Maybe you want something like this:

  SELECT id

  parentid

  version #.

  The EMPLOYEE

  WHERE CONNECT_BY_ISLEAF = 1

  START WITH parentid IS NULL

  CONNECTION BY parentid = PRIOR id

  ;

  The output I get from your sample data is:

  PARENTID EXTRA STRONG VERSION

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

  1                    1

  1                    1

  7          5         5

  6                    1

  8                    1

  Did you mean to have 2 identical rows in the table with id = 1?  If so, but you only you one of them appear in the results, use SELECT DISTINCT.

  Why you don't want to ID = 6 in the output?

  When you talk about "max version" do you mean the highest value, or the deep hierarchy?  In other words, if you have changed the row with id = 4 to be

  INSERT INTO EMPLOYEE (id, parentid, version #)

  VALUES (4, 3, 300) - version # was originally 3

  /

  the version 'max' in the output would still be 5, or would it be 300?

• Issue of SQL, to learn

  Can someone explain to me what / / means?
  
  CASES WHERE 1 = 1 THEN ELSE 0 0 END as the column alias_de_colonne
  
  or
  
  CASES WHERE 1 = 1 THEN 0 1 END as the column alias_de_colonne ELSE
  
  ?
  
  There are 3 tables that join each other and I select a few columns of A, B and C,.
  but then there are over this case and it is not referencing a Table at all, and I'm trying to
  to understand what this does? :-) with that 1 = 1 company, thank you!
  
  Thank you!

  CASE WHEN 1=1 THEN 0 ELSE 1 END as column column_alias
  

  Well, if I ask you "true or false: 1 = 1'? What would you say?

  A condition like '1 = 1' is used when you want to always set to TRUE. Similarly WHEN 1 = 0 will always evaluate to FALSE.

  In the code above "0" will always be returned since 1 'will always be equal to 1'. The ELSE and the rest is just to complete the CASE statement if you do not have a syntax error.
  This query returns a line

  select * from emp where 1=1 and empno = 7369
  
  EMPNO,ENAME,JOB,MGR,HIREDATE,SAL,COMM,DEPTNO
  7369,SMITH,CLERK2,7902,12/17/1980,4567,,20
  

  and it does not work

  select * from emp where 1=0 and empno = 7369
  

• E4x delicate issue of filter?

  Hello
  I Googled it for a day. I have not found answer. I have an xml with inlets tag man node. I want to tag entries based on a filter condition. Here is a sample of my xml data.
  
  
  I want to search all the nodes of the tag with the given string somewhere in the value. For example, I want to find all nodes with 'book' in them. All of the examples of e4x on the net talking about filtering based on the attribute of the current node or child. But not the value of the node it self. I am newbee actionscript. I wonder if there is a way to do it. I know that I can use for the loop and iterate on each node. I'm looking for the e4x expression that made it easily.
  
  var myroot:XML =... / / the XML root, I got to the end
  var tags: XMLList = myroot.tag. (??????????????????????); What is the condition of filter that does
  
  Thank you
  Videoguy

  I thought about a way to do this. Thanks for your example that has a call to text(). That's what I did.

  var tags: XMLList = myroot.tag. (text () .indexof ("book") > = 0);

  It made me what I am looking for.

• I found flaws in all of the calendars and the scientific calculators of Apple products. How can I send you my report pages 20 as a matter of course. Who should I go. This is a real case, and I am willing to work with Apple on this issue.

  Dear Sir/Madam,

  Topic: Default in some Apple products (important issue).

  This is not an unsolicited idea or suggestion (Please read)

  First of all, allow me to introduce myself as a teacher of mathematics, with more than 20 years of experience in the teaching of mathematics in Jordan.

  I take the liberty to write to you on a very delicate issue regarding the above topic. I'll try to be direct and fertilizers to point.

  Eight months ago, I have established contacts with the customer at Apple and succeeded to in explaining my intention to work with Apple on the flaws I found in all the following Apple products:

  -Scientific calculators built into the Apple iPhones and other products like Mack book pro (13 keys/operators applying bad mathematical concepts).

  -Calendars integrated into Apple iPhones and iPads (after a certain date).

  -Most of the calculators downloaded on Apple iPads (application).

  With my main concern during the final user, I already have reports submitted to Apple on the six keys with solid evidence and evidence supported with excerpts from various reliable resources that are no doubt as to the failure of these keys. I also presented copies of the date on which the calendar goes off track.

  Now iPhones for new generation of Apple (6s and 6 s-Plus) have already been launched on the market, keeping the same flaws, I decided to start contacts with Apple once again, hoping to succeed in reaching the right people at Apple to continue my rage in finding that the right to address this issue. I hope that you will respond positively.

  My worries and concern are oriented towards the end user and, in particular, students who take the responses of these calculators for granted when they are wrong and they don't realize.

  I have prepared a 20 page report although detailed on these defects and how to correct function solid evedence of reliable math textbooks. I'm ready to send this report to the person/department concerned, on which they can check and verify my claim with any or all of the following:

  ·       Apple/mathematicians engineers.

  ·       The mathematics books that are published by well known/good reputation

  publishers.

  ·        Calculators Casio or TI as the most reliable calculators in the world.

  ·        Reliable sources of mathematics of the internet.

  ·        Presentations power point math on YouTube.

  .        Math teachers well known working in renowned universities

  ·        American Mathematical Society.

  I reiterate my willingness to cooperate on the question above so that the genetions coming Apple products will be free by all means!

  I look forward to your positive reply,

  Sincerely,

  Nael
