simplify a query

Hi all

on 11.2.0.4 on Windows

The following query works:

SQL > select name, grip, duration, to_number (to_char(adhesion,'yy')) + duration mydate, to_number (to_char (sysdate, 'yy')) members Mr kdate

2 where to_number (to_char (sysdate, 'yy'))-(to_number (to_char(adhesion,'yy')) + length) > = 2;

LENGTH OF NAME MYDATE KDATE GRIP

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

LOMOBO AUGUST 2, 12 1 13 15

I try to write in a simpler way, but does not work:

SQL > select name, grip, duration, to_number (to_char(adhesion,'yy')) + duration mydate, to_number (to_char (sysdate, 'yy')) members Mr kdate

2 where kdate-mydate > = 2;

where kdate-mydate > = 2

*

ERROR on line 2:

ORA-00904: "MANDATE": invalid identifier

Thanks for help.

A select statement with a view online is always a single select statement. But I get your point. You can't refer to an alias specified for a column name in a select statement in a where clause of the statement itself select clause.

Also, your technique of conversion applied to get the year does not look good. You used the AA. Year has 4 numbers if you want to subtract 2099 and 1999 your approach will return 0. If you can tell what you're trying to achieve we can help you to solve it in an appropriate way without going over everything that conversions.

    Here's a DOF from two tables

    1. CREATE TABLE (EMPL)
    NUMBER OF SNO
    ENAME VARCHAR2 (25).
    USE VARCHAR2 (25).
    KEY ELEMENTARY SCHOOL (SNO)
    );

    2. CREATE TABLE EMPL_DET)
    NUMBER OF SNO
    SAL VARCHAR2 (25)
    );


    Here are tables LMD
    INSERT INTO EMPL (SNO, ENAME, JOB) VALUES (1, 'SMITH', 'CLERK');
    INSERT INTO EMPL (SNO, ENAME, JOB) VALUES (2, 'SMITH', 'MANAGER');
    INSERT INTO EMPL (SNO, ENAME, JOB) VALUES (3, 'TOM', 'CLK');

    INSERT INTO EMPL_DET (SNO, SAL) VALUES (1, '1000');
    INSERT INTO EMPL_DET (SNO, SAL) VALUES (2, "10000");
    INSERT INTO EMPL_DET (SNO, SAL) VALUES (3, '900');


    I want to calculate TotalSAL (column: empl_det.) SAL) of each employee (empl.ename) with job-description (empl.job).

    Means I want following the lines of output
    1.(Job,TotalSAL,Ename)-> (CLERK, 11000, SMITH)
    2->.(Job,TotalSAL,Ename) (MANAGER, 11000, SMITH)
    3->.(Job,TotalSAL,Ename) (CLK, 900, TOM)

    I tried to write down to unique ename

    Select JOB, x.sal, ename in empl,
    (
    Select sum (sal) sal empl_det where sno in
    (select sno to empl where ename = 'SMITH')
    ) x
    where ename = 'SMITH '.
    order by ename

    each ename, I draw from this query. How can I make the ename list (TOM SMITH) to this request?
    Or can anyone simplify this query?

    Hello

    in this case, you need to use is analytical functions:

    that is to say:

      SELECT e.job, SUM (d.sal) OVER (PARTITION BY e.ename) AS "TotalSal"
       , e.ename
    FROM empl e, empl_det d
   WHERE d.sno = e.sno AND e.ename IN ('SMITH', 'TOM')
ORDER BY e.ename;

JOB                         TotalSal ENAME
------------------------- ---------- -------------------------
CLERK                          11000 SMITH
MANAGER                        11000 SMITH
CLK                              900 TOM

    Kind regards.

  • How to simplify this query in sql simple select stmt

    Hello

    Please simplify the query

    I want to convert this query in a single select statement. Is this possible?
    If uarserq_choice_ind is not null then

union all
Select max(utvsrvc_ranking) as val

    Without more information, we are unable to combine the two queries in 1 without a union.
    Looks like you select values totally disperate of totally different tables

  • [8i] not to simplify this query?

    In my application, I need to pick up three possible prices for each part number in an array.
    The three possible prices that I need to recover are:
    (1) the price paid on the order more recently closed,
    (2) the price mentioned on the first pending order, and
    (3) the price on the furthest on pending order.

    However, there is a complication in that. Orders include the part number, but may also include a prefix of 4 characters (always the same) on a reference number which should be treated the same as the reference database. For example, "DSB-part1" should be considered "part1", "DSB-part2" should be regarded as 'part 2', etc.

    In addition, it is quite possible for several orders expected or closed on the same day, and I want to only return the price of one of these lines for each of the 3 methods of pricing.

    (Technically, there is another level of complication to this, but if I have problems with it later, I'll create a new job for him...)

    Whenever you want to have a WHERE clause only applies to certain columns, think about a pivot and expression BOX.

    Is there a reason to have raw triling part_no or ord_part_no?

    After this announcement, I saw that Max had posted essentially the same query.
    In general, where the solution of Max seems more simple, I like her way better.
    The only possible exception is tested for "OP" at the derivation of the values first_open and last_open. If none of the lines to an ord_stat part_no = "OP", solution of Max will be used a the lines with another ord_stat. That does not occur in the sample data, and I don't know if this is still possible in your application, but if this is the case, I don't know this isn't what you want.

    Hi gurus

    I have the following data:

    Drop table

    DROP TABLE lb_source;

    DROP TABLE lb;

    Insertion and table creation

    CREATE TABLE lb_source
    (
    source_cd VARCHAR2 (5)

    );


    INSERT INTO lb_source
    (
    SELECT 'a' STARTING from two
    UNION ALL
    SELECT 'b' double

    Select 'l' to double
    );

    CREATE TABLE lb
    (

    source_cd varchar2 (5)
    );

    INSERT INTO lb
    (
    SELECT '100', 'l' FROM dual
    UNION ALL
    SELECT '100', double null

    );

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

    If you see table lb then it contained a line with source_cd = l against 100 and source_cd = Null group against group 100, now I want to create this kind of query, in which all correspondence lines in tables to join both if lb is null, then query join all the source_cd of table lb_source except source_cd = 'l '. So far, I created the following query and its works ok but I want to do all my work in one in where condition...

    Query

    SELECT * FROM

    (

    SELECT s1, s2 b.source_cd A.source_cd

    OF lb_source A

    lb b

    WHERE A.source_cd = nvl (b.source_cd, A.source_cd)

    )

    WHERE s2 IS NULL

    ;

    Result

    s1 s2

    a null value

    b zero

    l null

    Please guide

    Hello

    So, you want something that produces the same accurate results as the query you posted, but does more just; Isn't it?

    Here's one way:

    SELECT ls.source_cd S1

    NULL AS s2

    OF ls lb_source

    JOIN lb l WE l.source_cd IS NULL

    AND ls.source_cd IS NOT NULL;

    I'm curious; What is the business problem that requires this request?  What tables and columns represent, and what tell you the query?

    Thanks for posting the CREATE TABLE and INSERT statements; It's very useful!

  • identifier is too long: expdp filtering using QUERY off TABLES =.

    All,

    I run large expdp work using a .bat file.  An example of one of the lines is the following:

    expdp directory "" / as sysdba "" = IMPORT_DB dumpfile=vismag_brightness%%U.dmp logfile = vismag_brightness.log ALL TABLES = sat_cat_owner.vismag_brightness QUERY = sat_cat_owner.vismag_brightness = compression:'------"where exists (" select visual_magnitude_uuid in the sat_cat_owner.visual_magnitude where sat_cat_owner.visual_magnitude.visual_magnitude_uuid=sat_cat_owner.vismag_brightness.visual_magnitude_uuid)\ "')"

    Present the results of .bat to this:

    OracleExportDataPumpIssues.png

    I then tried to put it in a settings file.  As always, you can see in the picture above, he already gave me an error, but I corrected which and he always gave me the same error.  The application was the same as above, only had no slashes return of evasion.

    Now this is why I am sure that I am right escape.  Now, I just need to find the reason for the identifier is too long.

    Here's a picture showing other odd behavior, trying to simplify the query to see if its because the query is too long.  AND if it is because its too long..how for I can config so it can handle?

    OracleSimpler.png

    The difference in the image above, is that the first test has only \"...while the second is what worked for me before top (if I try without the single quotes, it fails on citing the issue for the important query).  So the second cmd, as I have said, has "\" instead of just \"...and it does not work!"  When he did above for the larger request, but it gives error separated.

    Help, please!  Thank you

    Hello

    Try this instead

    Query ='sat_cat_owner.vismag_brightness: "Where exists (select visual_magnitude_uuid from the sat_cat_owner.visual_magnitude where sat_cat_owner.visual_magnitude.visual_magnitude_uuid = ku$ .visual_magnitude_uuid)" "

    Ku$ is an alias of special for the object currently being extraction - I think that in case you want to use exists, you must use this syntax - give it a try and see what happens.

    Other than that can replace you an IN clause instead?

    See you soon,.

  • A query containing a subquery and Group By all-in-one

    Hi people,
    Any interesting fact but nerve racking situation I have here. I have a question that I have to do counts and amounts and I also need to have a Sub inside query. When I run my application, I get an error like this:

group by to_char(c.start_date,'YYYY'), substr(acc.account_num,1,12)
order by 1;
    If I replace it with the acc.account_num (subquery) with a number that is in the database, then my request works well.

    Hello

    We don't know what you want. It would really help if you posted some examples of data (CREATE TABLE and INSERT statements) and the results desired from these data.

    Are you sure that the scalar subquery will return ever more than one line? If so, you can wrap in a MIN or MAX aggregate function, as I've suggested before:

     select distinct to_char(c.start_date,'YYYY') start_date,
         substr(acc.account_num,1,12) account_number,
   MIN ( ( select acc2.account_desc from student_account  acc2     -- Changed
         where  acc2.account_num = acc.account_num
         and    acc2.account_type = 'A'
       ) ),                                   -- Changed
       COUNT(distinct(s.student_id))
from student s,
       student_account acc,
       course   c
where s.course_id = c.course_id
and     s.account_num = acc.account_num
and    to_char(c.start_date, 'YYYY/MM/DD') between '2004/01/01' and '2009/12/31'
group by to_char(c.start_date,'YYYY'), substr(acc.acct_acc_num,1,12)
order by 1;

    It seems that you could also simplify the query and make more fast, eliminating the scalar subquery. The table there is already part of the main query, you can do something like this:

    SELECT    TO_CHAR (c.start_date, 'YYYY')     AS start_date
,         SUBSTR (acc.account_num, 1, 12)      AS account_number
,       MIN ( CASE
                    WHEN  acc.account_type = 'A'
              THEN  account_desc
                END
           )                         AS a_desc
,         COUNT (DISTINCT s.student_id)          AS student_id_cnt
FROM       student            s
,       student_account     acc
,       course          c
WHERE       s.course_id          = c.course_id
AND       s.account_num          = acc.account_num
AND       c.start_date          BETWEEN DATE '2004-01-01'
                      AND     DATE '2009-12-31'
GROUP BY  TO_CHAR (c.start_date, 'YYYY')
,            SUBSTR (acc.acct_acc_num, 1, 12)
ORDER BY  start_date;

    I guess that course.start_date is a DATE. Instead of converting each start_date to string (so you can see if it is in the right range), it is more efficient and less prone to error, compared to other DATEs, as shown above.

    It is very strange that you

    substr(acc.account_num,1,12)

    in the select clause, but

    substr(acc.acct_acc_num,1,12)

    in the GROUP BY clause. Did you mean having the same column in both places?

    Yet once, without seeing some examples of data (CREATE TABLE and INSERT statements) and the results desired from this data, I can't do much.

    Hello

    Thanks for posting the sample data in a useful form. That really helps.

    So you want a query that produces a line of output for each value in the column state.
    That's exactly what "State GROUP BY" don't:

    SELECT       state
,       COUNT ( CASE
                  WHEN  column_serviceable_a  = 'Y'
                AND   column_color_a         IN ('G', 'A')
                THEN  1
              END
            )
     - COUNT ( CASE
                  WHEN  column_serviceable_b  = 'Y'
                AND   column_color_b         IN ('G', 'A')
                THEN  1
              END
            )     AS cnt
FROM       cust_test
WHERE       area_oo     = 'Y'
AND       area_h     = 'Y'
GROUP BY  state
ORDER BY  state
;

    In fact, this becomes 0 as the county when no line meets the criteria of "has".
    If you prefer that NULL, as you posted, then replace the first indictment by AMOUNT:

    SELECT       state
,       SUM   ( CASE
                  WHEN  column_serviceable_a  = 'Y'
                AND   column_color_a         IN ('G', 'A')
                THEN  1
              END
            )
     - COUNT ( CASE
                  WHEN  column_serviceable_b  = 'Y'
                AND   column_color_b         IN ('G', 'A')
                THEN  1
              END
            )     AS cnt
FROM       cust_test
WHERE       area_oo     = 'Y'
AND       area_h     = 'Y'
GROUP BY  state
ORDER BY  state
;

    Output:

    STATE             CNT
---------- ----------
BANG
CHEN                2
HYD                 1

    Note that we do not need duplicate in this problem. Whenever you are tempted to use double, ask yourself why. See if the information you want to be taken from another table that you use when even.

    This should be much faster than the original request. Instead of making 2 passes through the table for each status value (2 * 15 = 30 past total), just make a pass through the table.

    Select extractvalue (value (x), ' / ns1:attribute / ns2:name ',' xmlns:ns1 is "http://webservices.mysite.com/test", xmlns:ns2 ="http://webservices.mysite.com/test" "" ") as the name

    )

    )

    ) x

    ;

    Namespace URI appear to be the same in your example of XML, if this is really the case, you can simplify the query and use the same namespace by default in any of the query.

  • CONNECT BY giving different results / duplicate records

    I have a hierarchy like this:

    UserTable-> username, treename_code

    username treename_code

    Scott TREE

    Henry TREE

    TREENAMES-> treename_code

    treename_code

    TREE

    subtree-> id, parent_id, treename_code

    ID parent_id treename_code

    1 null TREE

    2 1 TREE

    select case when connect_by_isleaf = 1 then 0
            when level = 1             then 1
            else                           -1
       end as status, 
       level, 
       subtree.id as value, 
       SYS_CONNECT_BY_PATH(subtree.id, '/') Path
  from usertable,
       treenames,
       subtree
  where upper(usertable.username)=upper(:username)
    and treenames.treename_code=usertable.treename_code
    and subtree.treename_code=treenames.treename_code
  start with subtree.parent_id is null
  connect by subtree.parent_id=prior subtree.id;

    Database version: 11.2.0.1.0

    According to the user, the order of results is different: we give values:

    1-2-2 (double on '2')

    gives another

    2 1-2 (always double on '2')

    BUT on another database, same version, it gives:

    1-2 (which is expected)

    Any idea?

    This is essentially because of the what the predicate to filter for the USER name is applied. If you are using an Inline view, you will get the desired result.

    Check this. I just simplified your query by removing just the other columns in the select list. But the CONNECT BY and are of the join of the table intact.

    SQL > select subtree.id
    2 usertable,
    3 treenames,
    subtree 4

    7 and subtree.treename_code = treenames.treename_code

    Here, the filter is applied before CONNECT you IS executed. This is the reason why you get the unexpected result in your query. Use the online mode.

    Hi, im sure that someone probably will this quickly.

    but for some reason any in my dissertation to result the order of the questions are always messed up, is there a way to keep the order of attribute?


    I tried an order around here, but this query is nested in many others. as I said, that basically, I just want to keep the order.

    Thanks BluShadow - but that removed a whole level which I can't do.

    Why? Put a different output?
    In your example, LEVEL1 and LEVEL2 can be combined in a single subquery, this is what BluShadow done to simplify the query and then apply the command without having to go QUESTION_NUMBER to the next level.

    If she asks problem in your real cases, keep the levels they are now and just add the ORDER BY clause if necessary.
    If you choose to do, you go QUESTION_NUMBER level 1 or 2:
