  In forms functions/procedures and forms triggers, you cannot use the SQL commands that did not exist in the 8.0 database.

  Oracle Forms (and reports) has a full PL/SQL engine and (only) the SQL parser.

  However, form (and reports) PL/SQL engine / SQL parser is at a level that was in the Oracle 8.0 database.

  With your version of Oracle and high-volumes of data through the analytical function, it is likely that this blog note applies. You may need a patch upgrade or special. http://jonathanlewis.WordPress.com/2009/09/07/analytic-agony/

• Which analytical function to use?

  
  Hi gurus,

  DB - Oracle 11 g 2

  I followed the examples of data in the table test_a.

  col1 col2 col3

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

  x                 y                   y

  p                 q                  y

  a                b                   y

  p                q                   y

  t                 r                    y

  p                q                   y

  The col3 column is always 'y '. But here's the data p, q, there is repeated 3 times (duplicate) and if this is the case I want to update only the first recordings like "n" col3 it is to say p, q, n. rest will be as it is.

  I am able to get the row_number() for it but not able to do this.

  Select col1, clo2, clo3 row_number() over (partition by col2) arrested by col1 as test_a r_num

  Would it be possible directly by any analytic function?

  Thank you

  Understand the logic and simply change SELECT a query to UPDATE...

  Analytical functions, such as the COUNTY and MIN, many global versions, in addition, it can give the same results.  Use the analytical versions when each row of output corresponds to exactly 1 row of input and the aggregate and GROUP BY version when each line of output corresponds to a group of lines 1 or more input.  In this issue, each line of output appears to be a group of input lines having the same group_id, part_type_id, and part_desc_id (I'm guessing just, this only has never stated), so I used GROUP BY to get 1 row of output for every input lines.

• Analytical functions: FIRST vs FIRST_VALUE

  Hello

  Can someone please help me understand the difference between PRIME and FIRST_VALUE in Anaytic functions.

  I tried below 2 queries, but I see the same output. The only difference I see is that the field of the SAL is ordered FIRST_VALUE, but not the FIRST.

  Hello

  Here is an example of when you can use the FIRST analytic function.

  Say you want the average sal for each Department, but only for the first year (taken from the hiredate column) in the Department (i.e., the column called f in the query below).

  WITH got_hireyear AS

  (

  SELECT deptno and ename, sal, hiredate

  EXTRACT (YEAR FROM hiredate) AS hireyear

  FROM scott.emp

  )

  SELECT deptno, hireyear, hiredate, ename, sal

  AVG (sal) DUNGEON (DENSE_RANK FIRST ORDER BY hireyear)

  COURSES (PARTITION BY deptno

  ) In the FORM f

  FIRST_VALUE (sal) over (PARTITION BY deptno

  ORDER BY hireyear

  ) AS fv

  AVG (sal) over (PARTITION BY deptno

  hireyear

  ), A

  OF got_hireyear

  ORDER BY deptno

  hireyear

  ename

  ;

  The analytical FIRST_VALUE function can do (except in the very special case where only 1 row has the lowest hireyear, as in deptno = 20).  AVG analysis can do (except in the very special case that all lines have the same hireyear as in deptno = 30).

  Normally, your developers are older than your software.

  You should be able to do what you want with a self-join on t2; a copy (d) should be displayed, and the other copy (c) contains all related values you need for comparison.

  SELECT t2d.id

  DECODE (t2d.place

  MAX (t2c.place)

  t1.description

  ) AS description

  t2d.place

  t2d.info

  FROM t1

• Analytical function?

  Hello

  I have two tables b rates and transactions (b).

  For each b.FS, I want to know new amount (b.amt time a.rate to the corresponding line of FS b and if a.na is valid based on the flag of the exclusion and the interval defined in the table's).

  It is much easier to explain with an example.

  So here we go...

  Exclude_flag = E (exclude): for b.fs = 433638, b.na = 80000. I have 2 lines in the table for this fs.  Both have E exclude_flag (exclude).  I want to go on all the lines in this FS in the table in a query and I return only one row in the result, if and only if b.na falls out of scope of a.na_min_value and a.na_max_values.  In this example, it falls outside the range excluded for both lines (first two lines of the table a).

  Similarly, exclude_flag = I (Include). for b.fs = 432828, b.na = 17200. I have 2 lines in the table for this fs.  Both have an exclude_flag of I (include).  I want to go on all the lines in this FS in the table in a query and I return only one row in the result, if and only if b.na is between a.na_min_value and a.na_max_values.  In this example, it falls in the range of both the range include for the two lines (line 6 and 7 of the table a).

  The following query gives me two lines for each b.fs.  It is possible to get what I'm looking for simply using sql (possibly write the analytical function?) or I have to write the pl/sql routine for this?

  @OP,

  For this kind of problems, we get the number of rows that satisfy the required conditions or who do not meet the required conditions. And then eliminate the line that should be eliminated.

  As below, I calculate four counts (number of join lines)

  EOBCNT - excluded and Out of Bound

  EIBCNT - excluded and in the limit

  IOBCNT - included and Out of Bound

  IIBCNT - included and within the limits

  Once those are calculated, simply return the lines that have EIBCNT and IOBCNT are zero.

  And here it is. "Acct_repres" subquery returns more than 300 lines when it is run separately. But when it is used in CTE sometimes (depending on the execution plan) she seems to have that one line - the value in the column col4 is '1 ',.

  While the value of col3 is NULL for most of the cases.

  It looks like the the dense_rank function and the State 'where odr = 1' are evaluated at the end.

  When I use the hint to MATERIALIZE the result was the same.

  But when I put the result of account_repres in the dedicated table and use this table instead of CTE output is correct.

  What is a bug? Or I do something wrong?

  PS: my version of db is 11 GR 1 material (11.1.0.7).

  some unorganized comments:

  -analytical functions are evaluated towards the end of the execution ("' the last set of operations performed in a query with the exception of the final ORDER BY clause"- http://docs.oracle.com/cd/E11882_01/server.112/e26088/functions004.htm")

  -but still the result of a SQL query must be deterministic, so I think that your results are not an expected behavior

  -the CBO has some problems with common table expressions (http://jonathanlewis.wordpress.com/2012/05/24/subquery-factoring-7/) if they are of great assistance in the structuring of complex queries. In these cases, you can avoid problems by using inline views

  -Your query uses the common table expressions in scalar subqueries and scalar subqueries are also likely to confuse the CBO. In addition, they are executed once for each row in your result set (or at least for each different correlation value) and can have a negative impact on the performance of the queries in many cases. Often, they can be replaced by outer joins.

  -you say that the suspicion of materialization brings you an erroneous result: the indicator object (online) gives you the correct results?

• Return one row of an analytic function

  Hello

  I pulled the following query:

  Select ID_STORNO, first_value (COD_CONTATTO) ON (Partition of COD_CONTATTO

  order of COD_PRIORITY asc, desc FT_DAT_OPEN_CNT

  rows between unbounded preceding and following unbounded)

  as COD_CONTATTO_LAST

  of WT_STR_ESG_CONTATTO;

  The result is:

  2160603	C1-H83J1N
  2160603	C8-9FOHXJS

  2258072

  C1-H83J1N

  But I just need to take the following lines

  2160603

  C8-9FOHXJS

  2258072

  C1-H83J1N

  Because for the same value of ID_STORNO, I just need to get a value of COD_CONTATTO (to select the best value using COD_PRIORITY and FT_DAT_OPEN_CNT). What is wrong inside the query? I just use 2 or 3 times the oracle analytic functions.

  Best regards

  As SomeoneElse... you need a where clause clause in order to choose the ones you want.

  To do this, the typical is to select a column that you use for this reason, such as:

  "I want to just the first record in each group..."

  Select id_storno, cod_contatto_last from)

  Select ID_STORNO, first_value (COD_CONTATTO) ON (Partition of COD_CONTATTO

  order of COD_PRIORITY asc, desc FT_DAT_OPEN_CNT

  rows between unbounded preceding and following unbounded)

  as COD_CONTATTO_LAST,

  ROW_NUMBER() OVER (Partition of COD_CONTATTO

  order of COD_PRIORITY asc, desc FT_DAT_OPEN_CNT

  rows between unbounded preceding and following unbounded)

  as rnum

  of WT_STR_ESG_CONTATTO

  )

  where rnum = 1

  /

  I prefer to use rownumber in this case, so I always have a rnum = 1...

  Usually, you must use the same partition/command by as your other folders (it is usually a good idea... maybe not, depending on your needs, however)

• Max date in analytic function

  I have records that a load dates repeat.
  I would like to return records with the maximum load_dates.

  It returns all the lines for some reason any.
  
  Any help or advice is much appreciated
  PJ

  max(load_dt) over (partition by load_dt) as mx_dt
  

  should be

  max(load_dt) over () as mx_dt
  

  If you want the maximum all the records, otherwise your was just the maximum per load_dt partition (think of partitions as being groups of data)

• Purpose of the ORDER BY clause in the analytic function Min Max

  I was always using analytical functions like Min Max without ORDER BY clause. But today I used with the ORDER BY clause. The results are very different. I would like to know the purpose of the ORDER BY clause in Min, Max and analogues of analytical functions.

  It is a good point that many developers are not so aware. As far as I understand it the way it works.

  Some analytical functions do not need an order by or windowing clause (SUM, COUNT, MIN, etc.). If there is no specified window, then the full score is the window.
  As soon as you add a command also add you a windowing clause. This window has the default value of 'rank ofrows between unbounded preceding and current_row. So as soon as you add an order by clause, you get a sliding window.

  Documentation: http://docs.oracle.com/cd/B19306_01/server.102/b14200/functions001.htm

  windowing_clause
  ...
  You cannot specify this clause unless you specified the order_by_clause. Window limits defined by the clause RANGE you can not specify only a single expression to the > order_by_clause. Please refer to 'Restrictions on the ORDER BY Clause'.

  example of

  with testdata as (select 10 numval, level lv from dual connect by level < 10)
  select lv, numval, sum(numval) over () sum1, sum(numval) over (order by lv) sum2
  from testdata;
  
  LV NUMVAL SUM1 SUM2

  Hey, Rod,

  My guess is that you want:

  , dense_rank () over (order by  tmstp  desc)  AS rn 
  

  RANK means you'll jump numbers when there is a link. For example, if all 3 rows have the exact same last tmstp, all 3 rows would be assigned number 1, GRADE would assign 4 to the next line, but DENSE_RANK attributes 2.

  "PARTITION x" means that you are looking for a separate series of numbers (starting with 1) for each value of x. If you want just a series of numbers for the entire result set, then do not use a PARTITION BY clause at all. (PARTITION BY is never required.)
  Maybe you want to PARTITIONNER IN cd. I can't do it without some examples of data, as well as an explanation of why you want the results of these data.
  You certainly don't want to PARTITION you BY the same expression ORDER BY; It simply means that all the lines are tied for #1.

  I hope that answers your question.
  If not, post a small example data (CREATE TABLE and only relevant columns, INSERT statements) for all of the tables involved and also publish outcomes from these data.
  Explain, using specific examples, how you get these results from these data.
  Simplify the problem as much as possible.
  Always tell what version of Oracle you are using.
  See the FAQ forum {message identifier: = 9360002}

  Why? What is the problem with the analytical functions? You have Oracle 11.2. Use it. Do not act as you have Oracle 8.0.

  One way to do that is a scalar subquery:

  SELECT    id
  ,       sal
  ,       (
            SELECT  1 + COUNT (*)
            FROM    table_x
            WHERE   id          = x.id
            AND     sal     < x.sal
         )     AS rnk
  FROM      table_x  x
  ORDER BY  id
  ,            rnk
  ;
  

  But it is extremely inefficient. This is an example of textbood (perhaps literally) why RANK is so useful.
