SQL & PL/SQL :: Query To Find Number Of Nulls For Each Record
Aug 18, 2013
We have data as below in the table. I need the to display the records in the order based on number of NULL values and position for each record.
provide a simple query using case in ORDER BY clause.
ID CLASS NAME DIST_ID DIST_NAME
0 NULL KIRAN 0 AP
0 C1213 NULL 0 AP
0 NULL NULL 0 AP
NULL C1234 NULL 0 AP
0 NULL NULL 0 AP
NULL NULL NULL NULL NULL
0 C123 RAJESH 0 AP
NULL C123 RAVI NULL AP
We have to give the rank based on NULL values and NULL value column position.Let us assume column positions as
1 2 3 4 5
ID CLASS NAME DIST_ID DIST_NAME
for the following three records number of NULL values are same. but positions are different.
0 NULL NULL 0 AP
NULL C1234 NULL 0 AP
0 NULL NULL 0 AP
NULL C123 RAVI NULL AP
Based on the column positions the ranks as
2*2+3*3=13
1*1+3*3=10
2*2+3*3=13
1*1+4*4=17
Which is having high rank (greatest number) that record should come last . The record which is having all values that should come first. The record which is having all NULL values should come last. The out put I want as
ID CLASS NAME DIST_ID DIST_NAME
0 C123 RAJESH 0 AP
0 NULL KIRAN 0 AP
0 C1213 NULL 0 AP
NULL C1234 NULL 0 AP
0 NULL NULL 0 AP
0 NULL NULL 0 AP
NULL C123 RAVI NULL AP
NULL NULL NULL NULL NULL
I need to find out that assume i have a table having 2 column
Num Name 1 Adam 2 Akanksha 1 barren 2 bosli 3 Benergee 4 Bhawna 3 anjani
I want a query as if A is there 2 times then there should be 1 then 2 then there is b coming in 4 places then it should be 1 2 3 4 and again there is anjani so 3 should be there as 1 and 2 in first 2 places and the num should be automatically generated number based on the count of the alphabets
We have a requirement where we need to pay allowance for the employees based on their number of working days. Say for example if an employee worked from 03/Mar/2012 to 05/Apr/2012.
We have a fixed value for per month 300 Dirhams. But the Number of Days on March s 31 and Number of days in April is 30. So per day allowance for March day would be 300/31 and April would be 300/30.
We are looking for logic opr query which calculates first eh number of days in each month ( across months) and then calculate as below
Number of Working days in March is 31 - 3 + 1 = 29
Allowance A1 = (300 * 29 )/31
Number of Working days in April is 5 ( this also needs to find logical I am guess ) Allowance A2 = (300 * 5 )/30
Then A1 + A2.
The A(n) would be the total allowance where provided the number of month across.
insert into call values(1,9818764535,9899875643,'IN','24-APR-13 02:10:43',10); insert into call values(1,9818764535,9898324234,'IN','24-APR-13 05:06:78',10); insert into call values(1,9818764535,9215468734,'IN','24-APR-13 15:06:78',10); insert into call values(1,9818764535,9899875643,'OUT','25-APR-13 01:06:78',10); insert into call values(1,9899875643,9899875643,,'OUT','25-APR-13 22:06:78',10);
Query : need to find first and last call of '9818764535' mobile number and of call_date between '24-apr-13' and '25-apr-13';
I need to create a query that returns record by record a field qty_progr with the cumulate qty considering previous records. The result should be the following:
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
I have a table where there is no sequence maintained and there is no time stamp column to track the inserted record.How do I find the latest inserted record in the table.
I have a table which is getting populated from a source. I dont have a time-stamp column in the table. Is there anyway to find the time when a record was inserted into the table?
i have form have one multi record block and sing record block. In multi record block having an item namely Excise_value. I want to find the sum of total Excise_Value for all the record. How to accomplish this.
PS: I want to use the Formula/summary property in forms
Am trying to extract data from oracle onto flatfile(.txt), am using UTL_FILE but, NULLs in oracle tables are getting converted into space and if i try loading into table it is getting loaded as space,
What I want to do is add is this logic: If Predirection is null, then no space between streetno & streetname. Same for postdirection and unitname. (for example, if both postdirection and unitname are null, there are no spaces between streettype and the comma before propertycity)
Also, when unitname is not null, I want to add the string "Unit " prior to the returned value in unitname.
I'm on 11.2.0.3. I want to write a query to get calculate a running total of incidents per day - this query will be used for an APEX line chart.Sample table and data:
create table sales ( id number primary key, time_of_sale date, item varchar2(20)); insert into sales values (1, to_date('02-JAN-2013','DD-MON-YYYY'), 'book'); ....
ct_id and limit_id is match column used for mapping.
now i want the total count of no of records in test_master in which test_master column value not exceed limit master column limit value if any one column exceeds its limit then the same row will be in my count criteria.
and user enters the figure like 13025now i would like to find the closest next value to the number entered by user, which is 713285 .how can i get this result, i have search a lot on Internet and i found some analytic functions can work out. but don't know how ..
I am currently working on a Data Dictionary project where we need to run a few rules against the give data sources to see if they all comply together.
One of the rule is to check if the no. is negative or not. So for that what I tried to do was to check if first the field is number or not and then check on if it is negative or not.
This is the code I am currently trying on and is not looking good.
SELECT 1 FROM DUAL WHERE decode(DECODE( TRANSLATE('-123.45','-0.123456789',''), NULL, 1,0), 1,substr('-123.45',1,1) ,' ' ) = '-'
if there is any inbuilt function or way to find a row in the table that is having value for maximum number of columns.
For example, the table A has 5 columns (c1,c2,c3,c4,c5) and it has 3 records(r1,r2,r3) and r1 has values only for c1,c2 r2 has values only for c1,c2,c3,c4 r3 has values only for c1
so I should get the result as "r3 has values for 4 columns & it is not having value for column c5".
