Analytical function - County not null record


Hi all

Is it possible to count the column records is not null using anlaytical?

Count (Column = 1) on)

Thank you.

«count (col) over (...)»  counts only non-null values...

Some examples of data with tables to create and insert queries so that we can help you...

See you soon,.

  • FIRST analytical functions returns the null line

    The following query returns a null line when there is no such thing as a line for the predicate. Is it a bug or expected behaviour. If so what is the meaning of the null row, is it not logical?

    Moreover, in my example how I distinguish the case where a line really exists, but the column is null when there is no such thing as a line and the FIRST function returns the same value null? Hopefullly I should be able to do it in a single SQL and know the difference?

    COUNT (*) > 0, but COUNT (col_x) = 0, then there is a line, but col_x happened to be null.

    For example, the following query shows that there is 1 row in the group with the lowest name ("ADAMS"), but the column comm in all ranks of this group is null:

    SELECT     COUNT (*)    KEEP (DENSE_RANK FIRST ORDER BY ename)
                          AS total_cnt
,     COUNT (comm) KEEP (DENSE_RANK FIRST ORDER BY ename)
                          AS comm_cnt
FROM     scott.emp
;

    Output:

     TOTAL_CNT   COMM_CNT
---------- ----------
         1          0

    The employee whose highest name ("WARD") has a number in the comm column.

  • 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;

  • by using the analytical function to get the right output.

    Hello all;

    ... Please note, I'm still learning how to use analytical functions.

    It doesn't matter; analytical functions will not help in this problem. The SUM aggregate function is all you need.
    But what do you need to GROUP BY? What is the value of each row of the result will represent? A placeid? Yes, each line will represent only placedid, but it will be divided further. You want a separate line of the output for each placeid and every week, then you'll want of the week and GROUP BY placeid. You don't want to GROUP BY the raw issuedate; that would put on 3 March and 4 March in separate groups. And you don't want to GROUP BY failures; This would mean that a line with 3 failures could never be in the same group in line with 9 failures.

    This becomes the output you posted from the sample data you posted:

    SELECT       placeid
,             TO_CHAR ( TRUNC (issuedate, 'IW')
              , 'MM/DD/YYYY'
            ) || ' - '|| TO_CHAR ( TRUNC (issuedate, 'IW') + 6
                                         , 'MM/DD/YYY'
                           )     AS issueperiod
,       SUM (failures)                  AS sumfailures
FROM        temp_one
GROUP BY  placeid
,            TRUNC (issuedate, 'IW')
;

    You can use a subquery to calculate TRUNC (issuedate, 'IW') once. The code would be of about as complicated, efficiency probably will not improve substantially and the results would be the same.

  • I want to record with &lt; alt &gt; &lt; s &gt; in the Exact program online. This function does not work. This is the first time I use this program with firefox.

    Question
    I want to record with < alt > < s > in the Exact program online. This function does not work. This is the first time I use this program with firefox.

    edit, escaped mod < s > in order to avoid the line through question

    A web page can be defined a "accesskey" for an item. Unlike IE/Chrome/Safari, who use the Alt key only, Firefox requires pressing Alt and Shift to activate the element. In other words, try

    ALT + SHIFT + S

    and see if it works.

    I don't know of any way to change this so that the change is not necessary. There may be an add-on?

  • ODDM 4.1.1.888 transform script function getProperty() does not return NOT NULL;

    Hello

    In the 4.0.0.833 version the funcion getProperty() returns NULL when the dynamic propertyare not out,

    e.g. VRFDA = table.getProperty ("Text"); -Returns a null value if the dynamic property 'Text' does not exist. The Variable VRFDA is nothing

    I have version 4.1.1.888 and the GetFilter() function returns DO NOT null when the dynamic property does not exist.

    Could you tell me what value returns the GetFilter() function when the dynamic property does NOT exist?


    Thank you

    In version 4.1 the getProperty function will return an empty string if the dynamic property does not exist.

  • Report Builder 6i do not recognize the analytical functions

    Hi all, in an attempt to speed up a slow query, I applied the analytical function to it. I can save the query in the generator without any problem, however, I can't create data between this request and other links. After I have comment on the analytical function, data bindings can be made. My colleague says Report Builder 6i is too old so he can recognize only the ANSI SQL syntax. Since our server DB uses Oracle 10 g 2, is there a way for the generator of reports to identify and compile syntax of Oracle 10 g?

    Thank you very much.

    Hello

    Your colleague is right. Even if the SQL query is executed by the DB server, reports must analyze the SQL query.

    The SQL parser included in reports 6i-based 8.0.6

    You can see this version using the report designer:

    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}

  • Need help to resolve the query by using analytic functions

    Hello

    I need help to solve this problem, I tried an analytical function but could not solve the problem.

    I have three table as illustrated below the table is filled with a flat file. The records are arranged sequentailly based on the name of the file.

    The first record of the game based on EIN goes to TAB_RCE
    the following records then goes to TAB_RCW
    and last save of the game based on EIN goes to the RCT table

    How can I make groups and
    assign a

    EIN * 12345 * line number * 02, 03, 04 * in the table TAB_RCW and * 05 * in the table TAB_RCT
    EIN * 67890 * line number * 07, 08, 09,10 * in the table TAB_RCW and * 11 * in the table TAB_RCT
    and so on...

    Thank you

  • Cannot use analytical functions such as lag/lead in odi components 12 c except in the expression

    Hi I am a beginner of ODI 12 c

    I'm trying to get the last two comments made on the product for a given product id. and load them into a target.

    I have a source table something like

    Product SR_NO comments LAST_UPDATED_TS

    1 good car 2015/05/15 08:30:25

    1 car average 2015/05/15 10:30:25

    Jeep 2 super 2015/05/15 11:30:25

    1 car bad 2015/05/15 11:30:25

    Jeep 2 horrible 2015/05/15 09:30:25

    Jeep 2 excellent 2015/05/15 12:30:25


    I want a target table based on their last timestamp updated as (last two comments)


    SR_NO Comment1 Comment2

    1                             bad                      average

    2 super excellent

    I used the logic below to get records in SQL Developer but in ODI 12 c, I'm not able to do this by mapping a source to the target table by applying analytical functions to the columns in the target table. Can someone help me solve this problem

    SELECT * FROM)

    SELECT SR_NO Comment1, LAG(Comment1,1,) ON Comment2 (SR_NO ORDER BY LAST_UPDATED_TS ASC PARTITION),

    ROW_NUMBER() ON RN (SCORE FROM SR_NO ORDER BY LAST_UPDATED_TS DESC)

    FROM Source_table

    ) M

    WHERE RN = 1

    ;

    UM, I'm afraid that ODI puts the filter too early in the request, if it generates:

    SELECT * FROM)

    SELECT SR_NO Comment1, LAG(Comment1,1,) ON Comment2 (SR_NO ORDER BY LAST_UPDATED_TS ASC PARTITION),

    ROW_NUMBER() ON RN (SCORE FROM SR_NO ORDER BY LAST_UPDATED_TS DESC)

    FROM Source_table

    WHERE RN = 1

    ) M

    ;

    Instead of:

    SELECT * FROM)

    SELECT SR_NO Comment1, LAG(Comment1,1,) ON Comment2 (SR_NO ORDER BY LAST_UPDATED_TS ASC PARTITION),

    ROW_NUMBER() ON RN (SCORE FROM SR_NO ORDER BY LAST_UPDATED_TS DESC)

    FROM Source_table

    ) M

    WHERE RN = 1

    ;

    Even by changing the 'run on Hint"of your component of the expression to get there on the source, the request will stay the same.

    I think the easiest solution for you is to put everything before the filter in a reusable mapping with a signature of output. Then drag this reusable in your mapping as the new source and check the box "subselect enabled."

    Your final mapping should look like this:

    It will be useful.

    Kind regards

    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.

    If you look at the output above, it dates back in the min_dt_from_grp column.

    MY question is if the analytical function calculates for a particular/set group, which is by statute and for what min (date_from) partition is 25-apr-2007 for the GROUP H (Status column), then why I have different values returned by the query above in the min_dt_from_grp column.

    Hello

    Because you have specified an ORDER BY clause for the analytical function. In doing so, you calculate the rows on a window. Since you have not specified a windowing clause, the default applies:

    RANGE BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW

  • 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.

  • Order of evaluation of analytic function

    Hello

    have question quite like this:

    with

    -This query selects a 'representative' acct_id by Group (about 300 lines in total)

    acct_repres as

    (

    Select distinct acct_id, origin_id, acct_parm_id of

    (

    Select a.*

    source_id

    , dense_rank() over (partition by order source_id by nulls first, acct_id acct_nbr origin_id) as odr

    account a join account_parm on (a.parm_id = ap.acct_parm_id) ap

    )

    where odr = 1

    )

    Select col1

    col2

    , (select accct_id from ar acct_repres where ar.acct_parm_id = t2.acct_parm_id) col3

    , col4 (select count (1) of acct_repres)

    of une_table t1

    Join other_table t2 on (...)

    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?

    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:

    2160603C1-H83J1N
    2160603C8-9FOHXJS
    2258072C1-H83J1N

    But I just need to take the following lines

    2160603C8-9FOHXJS
    2258072C1-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)
