I have been trying to find out how to write the following query:
Suppose the following table:
ID seq
24 1
24 2
24 3
67 1
67 2
67 3
67 4
67 5
13 1
13 2
I would like to retrieve the rows for every different ID with its max value. For one ID that would be:
select * from TABLE where seq in(
select max(seq) from TABLE where id=24)
How can i do this for all the rows??
To count the number of rows to the below table entries with certain conditions
my table
col1(varchar2(4000)) col2(varchar2(10))
3-1808116101 3-Standard
3-1808312141 3-Standard
3-1808312061 3-Standard
3-1807714441 2-Significant
3-1808284201 2-Significant
3-1808278361 2-Significant
3-1808284111 3-Standard
3-1807714261 3-Standard
3-1807128371 3-Standard
3-1807128351 3-Standard
3-1808301721 2-Significant
3-1808301701 3-Standard
3-1808322501 2-Significant
where conditions:
1)need to take the count of rows(col1).where col2 value is 3 or 2 .
2)value 3 or 2 is extracted and conditioned in the query
I am asking about the best way in SQL for the following case:
CREATE TABLE TRY_A (A NUMBER, B NUMBER);
INSERT ALL
INTO TRY_A VALUES (1,0)
INTO TRY_A VALUES (1,1)
INTO TRY_A VALUES (1,2)
INTO TRY_A VALUES (2,0)
[code].......
I need to learn the best way to select all A values where B is never 0. So if the needed result for the above example is:
A
--------------
3
5
As column B was never 0 with column A = 3 or 5.
Based on same salary i need to retrieve data like below whose hire date should be within a week (7days). The table may have 200000 records.
empno Hiredate salary

I have to write a query which will get records only if all the rows satisfies the condition.
Output should retrieve only 'A' because all the values are '1' Where as for 'B' only two rows having value '1'.
create table table1(field1 varchar2(100), field2 varchar2(10));
insert into table1(field1,field2)values('A','1');
insert into table1(field1,field2)values('A','1');
insert into table1(field1,field2)values('A','1');
insert into table1(field1,field2)values('B','2');
insert into table1(field1,field2)values('B','2');
insert into table1(field1,field2)values('B','1');
insert into table1(field1,field2)values('B','1');
SELECT field1
FROM table1
WHERE field2=all(select '1' from dual)
FIELD1
A
A

There are 4 rows in table with stat_flag 'Updated Record' and stat_date with todays date.
stat date has date & time both, for that reason just trying to format with yyyy.mm.dd
I am getting zero rows as result.
where STAT_FLAG = 'Updated Record' and to_date(stat_date,'yyyy.mm.dd') = to_date(sysdate(),'yyyy.mm.dd')
My requirement if id, join_date, join_time, result of table1 is matched with table2 at least one time then if repeating rows associated with the id should not come.Here is the test case.
create table table1
( id number , join_date varchar2(8), join_time varchar2(6), status varchar2(10));
create table table2
( id number , join_date varchar2(8), join_time varchar2(6), status varchar2(10));
insert into table1 values (01, '20010101', '0500', 'PASS');
insert into table1 values (01, '20010102', '0501', 'FAIL');
insert into table1 values (02, '20010103', '0502', 'PASS');
insert into table1 values (03, '20010104', '0503', 'FAIL');
insert into table1 values (04, '20010105', '0504', 'PASS');
insert into table1 values (05, '20010106', '0505', 'FAIL');

I have tried the below mentioned query, whether any better query is there than this because in real-time data have 2 millions of record in table 1 and 60 thousand in table2.
select distinct a.id, a.join_date, a.join_time, a.status
from table1 a, table2 b
where a.id = b.id
and (a.id, a.join_date, a.join_time, a.status) not in (select b.id, b.join_date, b.join_time, b.status
from table2 b)
and a.id = (
select distinct a.id

I got a requirement to check if a particular range of values are present , if few values missing then have to add null for the values. This has to be a SQL statement.
table 1 :
fiscal_month_id, value1, value2
2010100028482848
2010110025712709.5
2010120027452721.3
2011010026052692.25
2011020026382681.4
2011030030992751
2011040027662753.14
2011050029732780.625
This is the table. the fiscal month id denotes that the values is from month Oct(20101000) to May (20110500). The fiscal year cycle for me is from OCT to SEP. Hence when we select this table, the select should retreive the below data
fiscal_month_id, value1, value2
2010100028482848
2010110025712709.5
2010120027452721.3
2011010026052692.25
[code].....
How to do this in a select statement ?
This fiscal_month_ID is actual from another table where all time level information are kept.
For one example table t1 as below, I want to find the maximum 5 biggest size, but there should not be more than 2 name from the same position.
Name Position Size
N1 P1
N2 P2 50
N3 P3 500
N4 P1 6
N5 P2 60
N6 P3 600
N7 P1 7
N8 P2 70
N9 P3 700
I have a table that partitioned into six partitions. each partitions placed in different table space and every two table space placed it on a different hardisk
when I will do query select with the non-partition keys condition, how the search process ? whether the sequence (scan sequentially from partition 1 to partition 6) or partition in a hardisk is accessed at the same time with other partition in other hardisk. ( in the image, partition 1,4 accessed at the same time with partition 2,5 and 3,6)
in my sql we can use limit to select first 4 rows in the table then next 4 rows ,can oracle do that ?

I am trying to find records in table A that don't have any corresponding records in table B
select a.ID,a.templatenames from cbe a where not exists (select 1 from cbe_child b where a.ID=b.cbe_id)

I would like to know how to increase the result set of a 'Select' statement? I did a 'Select' that should have returned 36,000 rows and got only 5000 rows. What access level do I need to change this and what do I need to change? I am trying to do a migration of data from a delimited file to a table in Oracle. Yet, the data has to be filtered out prior to loading to the table?
SQLSELECT MIN(major_zipcode)
FROM TEMP WHERE MAJOR_CITIES IN (select distinct major_cities from temp);
My table has the follwoing 3 columns (in addition to others)
Col Name = active ; type=number ; values=1 (true) or 0 (false)
col name start_date ; type=date; format=dd-mmm-yy
col name end_date ; type=date; format=dd-mmm-yy
I need to select all rows where all active=1, start_date=<today and end_date=>today
my sql is: SELECT id, start_date, end_date FROM offers WHERE (active='1' AND start_date<='14-SEP-09' AND end_date>='14-SEP-09');
However the results are not right. Example, the first row returned is: Offer5000312 01-JAN-09 11-DEC-08
This is not correct. Due to the end_date this row should not be part of the results.
In sql plus How do I get the number of distinct rows of a certain value?
for example
select group_number from records group by group_number
How would I query for the total number of group_numbers in this query?
There are two tables like I posted below.I want a SQL query which selects all the rows from TABLE A which are not present in TABLE B. Also the select statement should pick all those rows which has updated value of COL_A2 in TABLE A.
TABLE A
COL_A1COL_A2
AAAMOBILE
BBBTABLET
CCCDESKTOP
DDDUNKNOWN
TABLE B
COL_B1COL_B2
AAAMOBILE
BBBUNKNOWN
CCCDESKTOP
The select statement should return following rows from TABLE A
COL_A1COL_A2
BBBTABLET
DDDUNKNOWN

I want to form a query that regardless of the total returned records, I will be able to specify how many of each "kind" of players I want returned. There are several good reasons that it has to be one query and not many.

We were trying to insert approx 76 million records worth of approx 4 GB in a table when the insert operation failed with the archive log error.
The database was hanged, we re-started the database and currently there are no records in the table but when we are firing a select
select count(*)
from table
It's taking approx 2 mins to come out with the result.
We checked and found that there are no locks on the table currently.

The above code is just to describe the sample table and the desired result set. Please note that Mary is not on the result set since she has no city assigned to her. Also Julia is not on the result set since she only has one city assigned to her. The others are there because they had at least 2 cities assigned to them.
I need the sql syntax that would return this result set.
