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)
Both tables have about 100 mil rows. And there is no Parent/Child relationship here, A.ID is a PK column.how can i write this select to perform better.
in my sql we can use limit to select first 4 rows in the table then next 4 rows ,can oracle do that ?
I have fifty rows inside the table
select * from student where rownum between 0 and 4 order by stuid ->it work
select * from student where rownum between 5 and 9 order by stuid -> did not work
what is the correct way to do it ?
Consider the following tables
MANAGERID
101
102
103
104
MANAGERID EMPID
101 ----------------24
101-----------------25
101 ----------------26
104 --------------- 27
write sql query to get the following output without using minus,union,intersect.
MANAGERID EMPID
101 ---------------------------------- 24
101------------------------------------25
101 -----------------------------------26
102 -----------------------------------N/A
103 -----------------------------------N/A

Question
How to select last 10 days rows only (from sysdate)
Error

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??
I have 3 tables that I want to select all rows from and then order by the timestamp of when the row was inserted.

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
select the rows from a table with the same particular field in PL/SQL. Actually I don't want to write two loops one inserted into another.

I have the following table:

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.
what do we need to do to get the performance back

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.
The query below returns 101 rows. If I replace the column list with an asterik the query returns 892 rows. I do not understand why.

I have a table which stores Employees and their Phone numbers. Each employee can have multiple numbers e.g.
Employee, Number
Adam, 123
Adam, 456

I need to get the super set(parent) record from a relational table. Following is the structure of the table,
create table relation (data_field1 number(20),data_field2 number(20),data_field3 number(20),
primary key (data_field1,data_field2,data_field3) );
insert into relation (data_field1, data_field2, data_field3) values (-10,123,334);
insert into relation (data_field1, data_field2, data_field3) values (200,123,334);
insert into relation (data_field1, data_field2, data_field3) values (300,123,334);
insert into relation (data_field1, data_field2, data_field3) values (400,123,334);
[code].....
Here '-10' will be considered as parent(super set) for all other values. If i have records like below,
-10 200 300
100 200 300
123 200 300
521 201 300
Output should only contain two rows. A super set row and other distinct row(second column value is not equivalent to super set).
I want to create a SELECT, that shall give back only a special amount of rows, depending on the sum of one of the selected fields.
At first a code sample of the complete selection:
SELECT DISTINCT mnr, ktxt,
(SELECT Sum(meng_4)FROM reldb d1 WHERE d1.mnr=d.mnr)qty
FROM reldb d
WHERE mnr IN (SELECT mnr FROM relac WHERE Lower(rlnr) NOT LIKE 'platte geprÃĪgt%')
AND saext='M'
ORDER BY qty DESC,ktxt;
This selection produces some lines of output (in my case i.e. like 300). What I want to see is only that much lines that the condition 'sum of all items listed below meng_4<=sum of all items meng_4 of the whole selection * 0.9' is fulfilled.
So, if the whole selection produces a total of 10000 as sum for all items meng_4, I want to see only that amount of rows that sums a total of at least 9000 for all items meng_4.
I hope, this specification is exactly enough to understand my intent.
1. Can I do this in a query?
2. If yes, what would this query look like?
nex lines showing SELECT DISTINCT return different rows when used with ORDER BY.
CREATE TABLE M1( ID_ NUMBER, A NUMBER, B NUMBER);
CREATE TABLE V1 ( A NUMBER, B2 NUMBER);
DELETE FROM M1;
DELETE FROM V1;
INSERT INTO M1 (ID_, A,B) VALUES (107, 5,1);
INSERT INTO M1 (ID_, A,B) VALUES (108, 11,1);

I am facing a problem in bulk insert using SELECT statement.My sql statement is like below.
strQuery :='INSERT INTO TAB3
(SELECT t1.c1,t2.c2
FROM TAB1 t1, TAB2 t2
WHERE t1.c1 = t2.c1
AND t1.c3 between 10 and 15 AND)' ....... some other conditions.
EXECUTE IMMEDIATE strQuery...These SQL statements are inside a procedure. And this procedure is called from C#.The number of rows returned by the "SELECT" query is 70.
On the very first time call of this procedure, the number rows inserted using strQuery is 70. But in the next time call (in the same transaction) of the procedure, the number rows inserted is only 50.And further if we are repeating calling this procedure, it will insert sometimes 70 or 50 etc. It is showing some inconsistency.On my initial analysis it is found that, the default optimizer is "ALL_ROWS". When i changed the optimizer mode to "rule", this issue is not coming.I am using Oracle 10g R2 version.
Our application servers will be running a SELECT which returns zero rows all the time.This SELECT is put into a package and this package will be called by application servers very frequently which is causing unnecessary CPU.
Original query and plan
SQL> SELECT SEGMENT_JOB_ID, SEGMENT_SET_JOB_ID, SEGMENT_ID, TARGET_VERSION
FROM AIMUSER.SEGMENT_JOBS
WHERE SEGMENT_JOB_ID NOT IN
(SELECT SEGMENT_JOB_ID
FROM AIMUSER.SEGMENT_JOBS) 2 3 4 5 ;
[code]....
Which option will be better or do we have other options?They need to pass the column's with zero rows to a ref cursor.
