  What I need to do...

  1 auto join to match EI for each partition ID

  2. THAT the date must be less than or equal to the date of the AE and when there is more then a line corresponding to this criterion has chosen the date of closest EI of the date of the ACE.

  3. it must be a full outer join because I want to show all lines, even if it is not a match.  There is a beginning, but not record end end gold but no record of departure

  4. If there is an AE line for many AS lines (the SA date is less then equals the date of EI) then join this AE line to all 3 rows of ACE

  5. the same rules for BS and BE.

  result should look like this.

  ID, date, code 1, id_1 code2, date_1, code1_1, code2_1

  Thanks for posting the CREATE TABLE and INSERT.  I know it can be a lot of trouble.  You want to get answers that work, not you?  Make sure that the statements you post too much work.  Test (and, if necessary, attach) your statements before committing.  You said code1 be VARCHAR2, but all the instructions insertion have values of 3 characters for code1.

  You are on the right track, with an analytical function, but ROW_NUMBER solves this problem.  1 "THAT line" could correspond to the 1st, 2nd, 3rd or any other line 'AE' and vice versa.  Try to use the analytical MIN function instead or ROW_NUMBER, like this:

  WITH got_next_e_date AS

  (

  SELECT id, eff_date, code1, code2

  MIN (CASE

  WHEN SUBSTR (code2, 2) = 'E '.

  THEN eff_date

  END

  ) OVER (PARTITION BY ID.

  , SUBSTR (code2, 1, 1)

  ORDER BY eff_date DESC

  ) AS next_e_date

  OF tab1

  )

  s AS

  (

  SELECT *.

  OF got_next_e_date

  "WHERE SUBSTR (code2, 2) s ="

  )

  e

  (

  SELECT *.

  OF got_next_e_date

  WHERE SUBSTR (code2, 2) = 'E '.

  )

  SELECT s.id

  s.eff_date

  s.code1

  s.code2

  e.id AS id_1

  e.eff_date AS eff_date_1

  e.code1 AS code1_1

  e.code2 AS code2_1

  S

  FULL OUTER JOIN e ON s.id = e.id

  AND s.next_e_date = e.eff_date

  AND SUBSTR (s.code2, 1, 1) = SUBSTR (e.code2, 1, 1)

  ORDER OF NVL (s.id, e.id)

  , NVL (SUBSTR (s.code2, 1, 1)

  , SUBSTR (e.code2, 1, 1)

  )

  s.eff_date

  ;

  Out (as you asked):

  ID EFF_DATE CODE1, CODE2 ID_1 EFF_DATE_1 CODE1_1 CODE2_1

  I guess code2 is always 2 characters, and the 2nd character is always ' or 'E '.

  I assume that the combination [id, eff_date, code2] is unique.

  If these assumptions are wrong, you need a few minor changes, but nothing big.

• [8i] need help with full outer join combined with a cross join...

  I can't understand how to combine a full outer join with a different type of join... is it possible?
  
  Here are some create table and insert for examples of database:

  Hello

  The query I posted yesterday is a little more complex that it should be.
  My_tab2.workstation is unique, there is no reason to make a separate subquery as mt1. We can join my_tab1 to my_tab2 and get the SUM in a subquery.

  SELECT       foj.workstation
  ,       foj.sum_my_value
  ,       foj.wkstn_name
  ,       mt3.my_nbr1
  ,       mt3.my_nbr2
  FROM       (     -- Begin in-line view foj for full outer join
            SELECT        mt1.workstation
            ,        SUM (mt1.my_value)     AS sum_my_value
            ,        mt2.wkstn_name
            FROM        my_tab1   mt1
            ,        my_tab2   mt2
            WHERE        mt1.workstation     = mt2.workstation (+)
            GROUP BY   mt1.workstation
            ,        mt2.wkstn_name
                          --
                  UNION ALL
                          --
            SELECT      workstation
            ,      0      AS sum_my_value
            ,      wkstn_name
            FROM      my_tab2
            WHERE      workstation     NOT IN (     -- Begin NOT IN sub-query
                                             SELECT      workstation
                                     FROM      my_tab1
                                     WHERE      workstation     IS NOT NULL

  She, exactly!
  The trickiest part is when and how get SUM (my_value). You could address the question of exactly what my_tab3 must be attached to a cross that's exactly what should look like the result set of the full outer join between my_tab1 and my_tab2 to. To do this, take your desired results, remove columns that do not come from the outer join complete and delete duplicate rows. You will get:

  workstation     sum(my_value)     wkstn_name
  -----------     -------------   ----------
  ABCD          30          WKSTN 1
  A123          35          WKSTN 2
  B456          0          WKSTN 3
  ????          5          NULL          
  

  So the heart of the problem is how to get these results of my_tab1 and my_tab2, which is done in the subquery FOJ above.

  I tried to use auto-documenté in my code names. I hope you can understand.
  I could spend hours explaining the different parts of this query more in detail, but I don't know that I would lose some of that time, explain things that you already understand. If you want an explanation of the specific element (s), let me know.

  Hello

  When you perform a JOIN EXTERNAL COMPLETE multi - build that way, whenever you add a new table, you can just join the previous table because this table could be all NULL values for a given row. You can reach each new table to the first table, either, for the same reason. You must enclose each new table with all previous tables, like this:

  FULL OUTER JOIN COL2 ON  COL2.ORG_ID     =           COL1.ORG_ID
                 AND COL2.CURRENT_DT =           COL1.CURRENT_DT

• Need help with Sql Tunning

  Under Update taking 2 h complete 3000 sets.

  I added more some condition where to reduce cost and its working fine. But I need to rise more than performance on SQL.

  Please help with SQL.

  I do not see the number of 3000 lines in the plan - so I guess that the optimizer does not compute with the correct numbers. Could generate the plan with dbms_xplan.display_cursor? This could tell us something about filter predicates and access.

  In the given situation, I would check:

  • is the access to the index in step 1 (filtered by the relevant conditions: this could be BATCH_ID = 26219) return actually 248 entries (or something similar)?
  • Access table in step 2 returning 204 lines (or something similar) after applying the filters given? If the number of lines is much bigger then a Nested Loops is perhaps not a good idea.

  To make this much simpler check, you could create a plan with statistics of content (RowSource) given that the plan containing the real and the number of estimated rows.

  If the estimated cardinalities are not plausible the next question would be if the statistics are strong and up to date.

• Diff "full outer join" is going. "(+)" SELECT syntax?

  As far as I know there are two ways to set an outer join:
  
  Select... from tab1 external t1 full join tab2 t2 on t1.id = t2.id;
  or:
  SELECT... from tab1 tab2 t2, t1 where t1.id = t2.id (+)
  
  They are absolutely equivialent?
  
  Who are the most common one?
  
  Who serve as well on other databases (DB2, MySQL)?
  
  Can I put an additional WHERE clause at the end of the first statement:
  
  SELECT... from tab1 t1 outer join t2 on t1.id = t2.id tab2 complete WHOSE...;

  Select... from tab1 external t1 full join tab2 t2 on t1.id = t2.id;

  It's FULL OUTER JOIN

  SELECT... from tab1 tab2 t2, t1 where t1.id = t2.id (+)

  It's LEFT OUTER JOIN.

  They are quite different.

  FULL OUTER JOIN - retrieves all the rows from tab1 and tab2

  LEFT OUTER JOIN - gets all the tab1 and lines than the line that matches the join condition of tab2.

  Here is a simple test.

  create table tab1(id integer)
  /
  create table tab2(id integer)
  /
  begin
    insert into tab1 values(1);
    insert into tab1 values(2);
    insert into tab1 values(3);
  end;
  /
  begin
    insert into tab2 values(3);
    insert into tab2 values(4);
    insert into tab2 values(5);
  end;
  /
  Select t1.id, t2.id
    from tab1 t1 full outer join tab2 t2
      on t1.id =t2.id
  /
  Select t1.id, t2.id
    from tab1 t1, tab2 t2
   where t1.id = t2.id(+)
  /
  

  Run it and see the result.

  I'm trying to get blogID, blogTitle, blogBody and the number of comments for each blog entry.  But, since I'm on to_char() for date and COUNT (commID) for the total number of comments, I am not "a group by expression.

  Here is an example of pseudo-SQL of what I'm trying.

  SELECT a.blogID, a.blogTitle, a.blogBody, to_char(a.dateEntered,'YYYY-MM-DD HH24:MI:SS') as dateEntered, COUNT(c.commID) as total
  FROM tableA a LEFT OUTER JOIN tableB b ON b.blog_ID = a.blog_ID

  WHERE a.blogID = '1'
  GROUP BY blogID, blogTitle, blogBody
  ORDER BY to_date(dateEntered,'MM-DD-YYYY HH24:MI:SS') desc
  

  I'm sure it's something simple, but I just DO NOT see it.  Can you help me?

  V/r,

  ^_^

  Try:

  GROUP BY a.blogID, a.blogTitle, a.blogBody, to_char(a.dateEntered,'YYYY-MM-DD HH24:MI:SS')

  SELECT DATE '' 2014-11-04 + LEVEL

  , TO_NUMBER (TO_CHAR (DATE '' 2014-11-04 + LEVEL, "YYYY"))

  OF the double

  CONNECT BY LEVEL<= date="" '2025-12-314="" -="" date="">

  ((mais je ne comprends pas pourquoi nous créons une telle table "année" et "period_label" peuvent être calculé à partir de startperiod))

• Help with SQL Query (Subselects)

  Hello community,
  
  IAM a new Member in this forum. The first excuse my English, my native language is German.
  In my workplace, we have a great Orcle Database 11 g with 30 different tables for production control issues.
  I try to get a couple of different information from the database, so I started with SQL of the query, but for this problem, I wasn't able to write a query to work.
  
  In this case, I have 2 tables:
  Table 1:
  ID; ORDER_NR; DESCRIPTION; CREATE_DATE
  1; A500236; CLEAN HOUSE; 20/02/2012
  2; A623555; REPAIR CAR; 10/01/2012
  3; A866944; MAINTAIN EQUIPMENT; 11/02/2012
  
  Table 2:
  ID; ORDER_NR; WO_STEP; STEP_DATE; EMPLOYEE
  1; A500236; A; 21/02/2012; W0010
  2; A500239; F; 21/02/2012; W0010
  3; A500239; S; 22/02/2012; W0027
  4; A500239; R; 23/02/2012; H0034
  5; A500239; U; 25/02/2012; L0099
  6; A263555; A; 15/01/2012; G0009
  7; A263555; C; 17/01/2012; S0039
  5 V A263555; R; 18/01/2012; K0059
  9; A263555; U; 19/01/2012; A0048
  10; A866944; A; 13/02/2012; H0034
  11; A866944; B; 13/02/2012; L0035
  12; A866944; G; 17/02/2012; D0084
  13; A866944; U; 23/02/2012; S0039
  
  And the result of my query should look like this:
  ORDER_NR; DESCRIPTION; CREATE_DATE; A_STAT_AGE; R_STAT_AGE; U_STAT_AGE
  A500236; OWN HOME; 20/02/2012; 5; 3; 1
  A623555; REPAIR CAR; 01/10/2012; 42; 39; 38
  A866944; MAINTAIN EQUIPMENT; 11/02/2012; 15; 4; 3
  
  The age of my query result should be calculated from the date of the creation of the order.
  I would like to know 2 things, one is how old was the order when they reached this status, R and U.
  The second, that is, how long did you order remaining on A stat, R and U (and if possible all the others too)
  It can happen that not every order reaches every State, so he ca go directly from A you in this case I want to display a generic character in this row/column
  
  I hope you all know what I mean and what result to expect.
  
  Thanks for your help.

  Hi Frank,.

  I thank you for your professional response and excuse my non-professional way to clarify my question.
  I have now already read and understand how to ask good questions, but is there an easy an inexpensive way to run a database on my computer at home?

  You can download the Oracle database from this site. The Express edition is easier to install. It lacks a few features that the Enterprise edition (for example, partitioning table and safety of level line), but most of the things work in all editions of Oracle.
  All editions are free if you do not use them for Production applications. Of course, at this price (or lack thereof), you get Oracle support.

  I have already noticed that the syntax SQL for Oracle differ from other DBMSS.

  Yes and some features are different in different products.

  Your query works perfectly, thank you.

  Now I want to refine my (your) query, is there a way to display a range of day within 1 day? As 0.5 day to half a day between two State timestamp.

  Of course, you can do it. After the exact output desired of the sample data that I posted. If the sample data do not show what you need to do, then after a few different examples of data that makes.

  My table contains the Date and time in a row, I forgot to mention that.

  After a CREATE TABLE statement. I was guessing a lot of things that may be important. For example, I assumed you were using a DATE for date and time column. So it is only reasonable to do so, but maybe it's not what looks like at your table.

  I tried something like this:

  SYSDATE - MIN ( CASE
                      WHEN  t2.wo_step = 'A'
                THEN  t2.step_date
            END
             ) AS Age_A
  

  But it gives me an error of arithmetic overflow and not die difference in the Date and time or days with decimal friction.

  There are only about 5.4 million possible days with DATEs of Oracle. Is only 7 digits and Oracle can treat approximately 39 numbers without overflow errors, so I don't see how this can happen if t2.step_date is really a DATE. This is an example of why you need to publish a CREATE TABLE statement.

• Join with conditions of outer join statement

  Hello
  The following was extracted from the 11 GR 2 document guide performance, which I am not quite understand.
  Can anyone provide some examples to clearly explain this. Thank you
  
  For join instructions examples with outer join conditions, the table with the outer join operator must come after the other table in the condition in the join order. The optimizer does not consider join orders that violate this rule. Similarly, when a subquery was transformed into an antijoin or a semi-join, arrays of the subquery must come after these tables in the outer query to which they were connected or block in correlation. However, semijoins and antijoins of hash are override this order condition in certain circumstances
