SQL & PL/SQL :: Generate Range Based On Start And End Number Dynamically?
Jul 14, 2011
I have following requirement. Let say i have to generate a range based on "start number" and "end number" dynamically.Some kind of hash buckets.
e.g Start Number : 1 and End Number : 1001.
Also i want to divide that range based on some dynamic value like for above example 10 ranges of 100 each. and both 1 and 1001 should be included only once and the next row start number cannot be same as previous row end number.
Means
Range 1 1 -101
Range 2 102-200
Range 3 201-300
...
Range 10 901-1001
Is there any way of doing it automatically. I tried with Model clause. it works fine for even cases but for odd i have issues also when i take small start and end number i get an error.
SELECT case when ranges=1 then ranges else ranges+1 end Start_Id, ranges+round((1001-1)/10) End_Id
from
(
[Code].....
I want this to be generic for any values here 1 is Start Number 1001 is end number and 10 is the bucket. I need these parameters dynamic and want's the same kind of results for any values.
formatting the data.I want to group the below table data based on the Grade column for a header_data with start_time and end_time displayed in range. I was trying with group by, partitions etc but no luck. I use version 10gr2.
My requirement is to concatenate two column values and place them in a new column.I have done it using self join but it limits the purpose,meaning when I have more than 2 values for grouped columns then it won't work.How to make this dynamic,so that for any number of columns grouped,I can concatenate.
SELECT a.co_nm, a.mnfst_nr, a.mnfst_qty, a.mnfst_nr || ':' || a.mnfst_qty || ';' || b.mnfst_nr || ':' || b.mnfst_qty FROM vw_acao_critical a JOIN vw_acao_critical b ON a.co_nm = b.co_nm AND a.mnfst_nr = b.mnfst_nr [code]......
What will be the case when I need to concatenate for more number of values.
like when co_nm has three bahs and manfst_nr and manfst_qty has 3 values for each for bah.and if three are having same_mnfst nr then I should use something dynamic.how to achieve this.
I have a table called 'orders' and having date and time of order placed in the field timeplaced. I need to generate a report which is having hourly based number of orders placed . If no order is placed in an hour then it should show 0 for that hour in the result .
How do you specify the value in START WITH dynamically during runtime. For example consider the bewlo scenario:
CREATE TABLE ISCT ( ITEM_NO VARCHAR2(15 CHAR) NOT NULL, ITEM_TYPE VARCHAR2(3 CHAR) NOT NULL, ITEM_TYPE_SCO VARCHAR2(3 CHAR) NOT NULL,
[Code].....
Now if you create a view:
create or replace view test_v (ITEM_NO, ITEM_TYPE, ITEM_NO_SCO,ITEM_TYPE_SCO) as SELECT T.ITEM_NO, T.ITEM_TYPE, CONNECT_BY_ROOT T.ITEM_NO_SCO,T.ITEM_TYPE_SCO FROM [Code] .......
Then run the below query:
select * from test_v where item_no_sco = '00245905' --
the output is got within a second. but the real scenario is that both table icont and isct have millions of rows. In that case even this small query of the view takes 10minutes as there a FULL TABLE JOIN.
How do I give the START WITH in the view to make it faster i.e. even with millions of rows the output of this comes in seconds:
write the query for the following requirement.I need to generate the records for the range (Difference between From_val & to_val) ) for each ID
create table test_base(id varchar2(20) , from_val number , to_val number);
insert all into test_base values ('A', 6,10) into test_base values ('B', 22,30) into test_base values ('C', 123,130) into test_base values ('D', 852,860) into test_base values ('E', 30 ,30) select * from dual ; [code]....
No need to generate any thing for E as the difference is equal to Zero
I am using PL/SQL Developer.I have two tables: A and BTable A contains serial_from and serial_to values.This is used to define the serial numbers issued to customers (i.e. the start and end range of serial numbers issued).Shown here for a client:
Table B contains the individual numbers, B.serial (within the serial_from and serial_to range) along with other data, and is only created when the serial is used by the client.
I would like to create a list of records for individual clients containing serial numbers issued but not used. i.e. they are in between the serial_from and serial_to values in Table A, but not in Table B.
How can I create a list of numbers issued, but not yet used? Because Table A contains only two values (to and from) no record exists for them, so how do I generate a list and check against it?
Is there any way to generate columns dynamically by depending on the rows in a table in 11G .
Ex: If the deptno in DEPT table is not constant,then how to generate the N numbers of columns based on the deptno. Below query is working when we hard coded the deptno (10,20,30,40).What else if we more number of departments and we don't know the departments also.
Connected to Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 Connected as dbo
SQL> SELECT * FROM (SELECT deptno, job, sum(sal) sal FROM SCOTT.emp GROUP BY job, deptno) PIVOT(sum(sal) FOR deptno IN(10, 20, 30, 40));
I need to pick a value based on range like if the range is as below
[code] if value =2000 then its 2000 elsif value >=2001 and value <=2499 it should be 2000 elsif value =2500 then 2500 elsif value >=2501 and value <=2999 it should be 2500 elsif value = 3000 then it should be 3000 [code]
Like this i need to pick a value by hardcoding this range and this look cumbersome in my program , is there a simple way to substitute this entire thing by passing one single value and getting one single value using a command or builtin.
I have the following select query that works perfectly fine. Returns 25 rows based on the descending order of the price.But, I want add one more expression to this list of columns in this query (apart from customer_id).
the expression should look like Cust-01 for the first customer from the below query all the way to Cust-25 for the last customer.But how can I can generate 01 to 25 in oracle?
select customer_id from (select customer_id from capitalPLAN where member_status = 'MEMBER' AND customer_id NOT in ('156','201','1385','2125','3906','165') order by price desc ) where rownum <= 25
Our term (strm) is dictated by the term_begin_dt and term_end_dt dates but I want to keep selecting that term until 1 week before the next term opens and then switch to that term.
Basically, I don't want any gaps between a term.
Output:
select strm when sysdate is between term_begin_dt and term_end_dt (strm would equal 3943) select strm until 1 week before the start of the next term (4027) (strm would equal 3943) select strm when 1 week before term_begin_dt (strm would equal 4027)
Repeat for the next term and so on 12/16/2011 select strm from term where trunc(sysdate) between trunc(term_begin_dt) and trunc(term_end_dt)
Output: 3943 12/17/2011 - 01/01/2012
select strm from term where ?
Output: 3943
01/02/2012 - 5/4/2012 select strm from term where ?
Output: 4027
Repeat.
Test Case:
CREATE TABLE TERM ( STRM VARCHAR2(4 BYTE), DESCR VARCHAR2(20 BYTE), TERM_BEGIN_DT DATE, TERM_END_DT DATE )
Insert into TERM (STRM, DESCR, TERM_BEGIN_DT, TERM_END_DT) Values ('3943', '2011 Fall Semester', TO_DATE('08/22/2011 00:00:00', 'MM/DD/YYYY HH24:MI:SS'), TO_DATE('12/16/2011 00:00:00', 'MM/DD/YYYY HH24:MI:SS')); Insert into TERM [code].....
I am new to PL/SQL, worked mostly on SQL server, I have to change the table name dynamically based on the parameter.and used a ref_cursor to display the results in a report. when I execute it throws me an error.
create or replace procedure test1 ( p_eod_date IN VARCHAR2, p_link IN NUMBER, c_rec IN OUT SYS_REFCURSOR) [code]....
I have a table in some db called retailer. I want to generate an email based trigger. What i want to achieve is as follows
I want to generate an email based trigger. What i want to do is that i should store the current retailer id which is until this point and then on each further insertions in retailer id i want that some trigger or script is running in background which is storing the retailer id. When the retailer id advances by 45 then a trigger should be generated saying that retailer id has advanced to 45 numbers from this date.
We have certain records like SQL, PL/SQL, Reports, Forms, OAF etc in a table. We wanted to capture rating for each of these criteria. So we want a form to be displayed dynamically..
I want to pass Number of columns dynamically to a query. I got success in SQL.
SQL> select &column_list from emp; Enter value for column_list: empno,ename,sal
EMPNO ENAME SAL ---------- ---------- ---------- 7369 SMITH 800 7499 ALLEN 1600 7521 WARD 1250 7566 JONES 2975 7654 MARTIN 1250 7698 BLAKE 2850 7782 CLARK 2450 7788 SCOTT 3000 7839 KING 5000 7844 TURNER 1500 7876 ADAMS 1100 7900 JAMES 950 7902 FORD 3000 7934 MILLER 1300
14 rows selected.
But the same i need to achieve in pl/sql. I try with the Ref cursor, but not succeeded.
I have a query that seems to repeatedly call an index scan on a table for reasons I'm not sure about. Why it would be doing the index scan on totaldwellingarea in the dimensions table (DIMEN_PID_TDWELLAREA) repeatedly? This only seems to happen when I put on the range clause d.totaldwellingarea between scr.lowvalue and scr.highvalue.
I am using Oracle version 9.2.0.3.
select d.propertyid,d.totaldwellingarea, e.size_, scr.size_ from eqid e, dimensions d, brt_eval.size_code_ranges scr where e.style not in ('1','A','G','L') and e.size_ = '0' and d.propertyid = e.propertyid and e.style = scr.style and d.totaldwellingarea between scr.lowvalue and scr.highvalue;

[Code]....
As per my knowledge, RANGE is better suited for DATE or NUMBER. and INTERVAL partition is possible on DATE or NUMBEr . Column PROFILEIts is of VARCHAR2 datatype. I know still I can partition as Oracle internally convert varchar2 to number while inserting data. But INTERVAL is not possible. How to RANGE partition on PROFILE ? Column CREATED_ON :It is of NUMBER with decimal
how do you generate serial numbers? i have an invoice where i have to add items, so i want the numbering to start from 1 everytime i start a new form and increment by 1 as i i enter a new record. For this i have put my code in when-new-record-instance but problem is if i delete a record and enter a new one, the serial number starts from the nex number.
For ex. if i have 4 items with serial numbers 1, 2, 3, 4 and i delete the item at no. 3 and add a new item , the serial number comes as 5.
I need generate an unique number without sequence. I am using Oracle 11.2, here is the details. The column idSeq is unique withing one specific idType. I don't want a sequence for each idType.
