many need help query step

Hi I met a problem while making this request.

I'm doing the query shows how many customers entered into a table of rental during the set time that I choose.

I am tempted to cross reference it with the amount of customers stored in the original customer table since the beginning of time.

That's what I came with, but I get the error that I have successfully completed my Sql

SELECT * FROM RENTAL WHERE RENTAL_DATE > = 1 January 14 ' AND RENTAL_DATE < = 10 January 14 ',.

COUNT (DISTINCT CUST_ID) AS NUMBEROFCUSTOMERS,

SELECT COUNT (DISTINCT CUST_ID) AS TOTALCUSTOMERS CUSTOMER

The top and the bottom of line work separately from this, but when I add the line in the Middle I have no chance.

Thanks in advance

First of all, ' 01-JAB-14' is not a date - it's a chain. Anyway, you can use an outer join:

SELECT COUNT (DISTINCT C.CUST_ID) DID TOTALCUSTOMERS,

COUNT (DISTINCT R.CUST_ID) AS TOTALRENTERS

CUSTOMER C,.

RENTAL R

WHERE C.CUST_ID = R.CUST_ID (+)

AND R.RENTAL_DATE (+) > = DATE ' 2014-01-01'

AND RENTAL_DATE (+)<= date="">

/

Or:

SELECT COUNT (CUST_ID) AS TOTALCUSTOMERS.

MAX)

(

SELECT COUNT (DISTINCT CUST_ID)

RENTALS

WHERE RENTAL_DATE > = DATE ' 2014-01-01'

AND RENTAL_DATE<= date="">

)

) AS TOTALRENTERS

OF THE CUSTOMER

  • Need help query subquery

    Hey guys,.
    I have a question that I can't wrap my head around. I have a table called traffic, and in this table I have tons of columns... I focus mainly on three pillars, VIOLATIONTYPE, TID, AND guid. When a judgment is made, it receives a uniqueIdm which is the GUID column.
    If more than one ticket is given to the individual, the guid remains the same. I need to write a query to find out how many warnings is emitted by the user who is TID column.
    The problem is, if more than one ticket has been assigned at the time of the stop and these tickets are not only attention, but also a quote, I won't count that stops traffic in my query.
    I just need all the stops that are strictly warnings.
    Of course, I know how to extract the warnings, but if the guid is a warning and reference both, I don't know how to remove the records in the query. Any help would be appreciated. The query below, I wrote is just the initial steps to get * him to stop before I eliminate records where a quote and a caveat had the same GUID...

    Select * from traffic where tid = "1234" and violationtype = "warning" and guid in (select traffic seq_guid b where a.guid = b.guid)

    Consider using a NOT IN or NOT EXISTS a subquery to allow lines with citations, something like (not tested)

    select *
      from traffic a
     where tid='1234'
        and violationtype = 'warning'
        and guid in (select seq_guid from traffic b where a.guid = b.guid)
        and not exists (select 0 from traffic c where c.guid = a.guid and violation_type = 'citation')

  • Need help with query

    Have the rank as below,

    -A2 200

    A3 300

    50 A1

    Need to query to extract the output like this:

    B1                     B2

    A1 + a3 (Sum) A2 (sum)

    Please help me out of this...

    Hello

    It is difficult to understand what you want... A guess based on many assumptions:

    -B1 and B2 are column headers,
    -"A1 + A3" and "A2" in the 'exit' is simply to indicate that you want the sum of the amounts for the first names.

    -Some of the AI have all their amounts > = 0, others have their amounts<=>
    -You want to make the sum of all positive numbers in the first column and all the negatives in the second column

    SELECT SUM (GREATEST (0, t.amount)) b1

    , B2 SUM (LESS (0, t.amount))

    MYTABLE t

    ;

    (I think there is only a bit of luck it's really what you want, but provide a full test case and the output that you really want and why not, try to explain / explicit rules, then we can give better help)

    Sorry, my bad. Without database at hand, I'll try 'baby steps' (borrowed from Frank) so you don't confuse it with errors that I might add (happens far too often already, but at least you won't "swallow" as forum members think is one of the main goals of this fighter - help her learn - providing not only the proverbial fish.)
    Search the Forum - your problem is one of its best sellers. Watching {message identifier: = 10694602} ("split string into" was the key word used in research) you can try something as

    select table_row,
           level clob_row,
           regexp_substr(char_data,'[^' || chr(13) || chr(10) || ']+',1,level) the_line
      from (select to_char(queue_seqnum)||':'||to_char(line_seqnum) table_row,
                   char_data
              from order_details
           )
     connect by regexp_substr(char_data,'[^' || chr(13) || chr(10) || ']+',1,level) is not null
            and prior char_data = char_data
            and prior table_row = table_row
            and prior sys_guid() is not null
    

    to get all the s the_lineall CLOB and after that the use of the example even to get your columns of each the_line.

    For "Created" count of status must be taken Support_issues table, for others it must be taken from table Support_comments.

    Please help me to form a query for this!

    Thank you

    Hello

    Try the following query

    with t1 as
    (
    select to_char(sysdate-level+1,'dd-mm-yyyy') as date_range from dual where level<16 connect by sysdate-16
    

    Cannot test because I did not create, insert commands...

    I need to find the year of greater subsidy for the granting by a period setting.
    Once I found the great year, I need to check the value of the period 14 this grant for the previous year and add it to the amount of the budget for this grant. However if there is an entry in the biggest year for period 00 so I need to ignore the period 14 of the previous year and the current calculation period + (current period - more great year 00)

    hope that makes sense, so in other words, with the new data above. If I asking me a second period of the grant year 11. I'd end up with $800

    because the greatest year is 11 it contains one point 0 with $ 400, so my total should be
    amount of period $2,600
    period $0 400 - period $2 600 = $200

    600 + 200 = $800

    If I have question period 1 grant 360055 I'd end up just with 800 grnt year 10.

    I tried to edit this query you have provided me with no luck. I tried for several embarrassed day but I'm saying I can just do what im trying to do.
    can you please help me.


    Here's the query provided by frank kulash who graciously put it together for me.
    WITH     got_greatest_year     AS
    (
         SELECT     fgl.*     -- or whatever columns are needed
         ,     MAX ( CASE 
                     WHEN  fgl_period = :given_period 
                     THEN  fgl_grnt_year
                    END
                  ) OVER ()     AS greatest_year
         FROM     fgl
    )
    SELECT     SUM (fgl_budget)     AS total_budget     -- or SELECT *

    Hi, Miguel.

    You are waying that when larger year who has: given_period also a period = '00' (or '0', or whatever it is you want to use), then you want to double the budget of the given_period (subtract the '00' budget and do not count '14' year pevious)? If so, add another condition to the CASE statement that decides what you've summarized:

    WITH     got_greatest_year     AS
    (
         SELECT       TO_NUMBER (fgl_grnt_year)     AS grnt_year
         ,       fgl_period
         ,       TO_NUMBER (fgl_budget)     AS budget
         ,       MAX ( CASE
                       WHEN  fgl_period = :given_period
                       THEN  TO_NUMBER (fgl_grnt_year)
                      END
                    ) OVER ()     AS greatest_year
         FROM       fgl
    )

    (
         SELECT     grnt_year
         ,     fgl_period

                       WHEN  grnt_year     = greatest_year
                       AND       fgl_period     = '00'
                       THEN  1
                         END
                    ) OVER ()          AS cnt_00
         FROM    got_greatest_year
    )
    SELECT       SUM ( CASE
                        WHEN  grnt_year     = greatest_year                    -- New
                  AND       fgl_period     = :given_period                    -- New
                  AND       cnt_00     > 0            THEN  budget * 2     -- New
                        WHEN  grnt_year     = greatest_year
                  AND       fgl_period     = :given_period       THEN  budget
                        WHEN  grnt_year     = greatest_year
                  AND       fgl_period     = '00'            THEN -budget
                        WHEN  grnt_year     = greatest_year - 1
                  AND       fgl_period     = '14'
                  AND       cnt_00     = 0            THEN  budget
                    END
               )          AS total_budget
    FROM       got_cnt_00
    ;
    

    You will notice it is the same as the previous query, I posted, with the exception of 3 lines marked 'new '.
