Dec 27, 2006I have 3 tables that I want to select all rows from and then order by the timestamp of when the row was inserted.

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);

I am trying to find sum for one record for each partition but while taking that timestamp giving me bit trouble, i have tried to reproduce the table and some little data

,TBL_NAME VARCHAR (4)
,PARTITION_NAME VARCHAR (240) )

I have employees under a supervisor defines as below:
select LOGIN_USER_ID from APPWMS.VIEW_EMP_LATEST_INFO where SPVSR_LOGIN_USER_ID='erbrand' and EMP_STAT_CODE='ACTIVE'
Now I need to determine if all above employees are clocked in , clocked out or not clocked between yesterday and today using following:
select to_char(CLOCK_IN_DATE,'dd-mon-yyyy hh24:mi:ss' ) ClockIn,to_char(CLOCK_OUT_DATE,'dd-mon-yyyy hh24:mi:ss' ) ClockOut ,LOGIN_USER_ID,--CLOCK_IN_DATE,CLOCK_OUT_DATE, CLOCK_OUT_DATE-CLOCK_IN_DATE,trunc(sysdate) , trunc(sysdate-1),
case when CLOCK_OUT_DATE is null then
'Not clocked out'
else
[code]....
The first SQL gives me 66 rows while second gives me 40 rows. For 26 people , no rows are returned which means these people donot have a clock in record between two timestamps.
How can we modify query to show those 26 people as 'Not clocked In'
Due to some business requirements a table field needs to change from date to timestamp in order to handle the millisecs.
1>When i alter the row , for a table with 150 million recs will there be a conversion. Is there a recommended way to convert the field. Mind you this field is used as a part of composite PK.
2> There is a interfacing application which connects and copies the data to its system and is using the date type, will that application be able to continue to work without any changes, if it does not care about the millisecs.
3> Will there be performance impact on an existing application that uses the date field to sort
4> Will DB need more space due to the change
In a query which gets executed first:
Select clause or Order by clause? First the columns specified in the select clause are fetched and then ordered or is it the vice -versa? In a query if a psuedo-column rownum is selected, then if we use order by on the rownum column, what happens?
What would be the output of the following query and why?Which part of the query is first executed, is it select clause or order by clause?
select empno,ename,rownum from emp order by rownum desc;
Here is my query to fetch only 10 records from order by result set.
select *from (select * from EOE_POC.PRODUCT_TEST_REPORT where PRODUCT_CODE='214d' order by CREATE_DATE desc ) where ROWNUM <= 10
I am having problem binding it with java API . how to query this without using sub query ?
I would like to write a select statement on a table and I want the records to be retrieved in the order they were inserted.

CREATE TABLE test_A(member_id NUMBER(2) PRIMARY KEY, MEMBER_name VARCHAR2(20), MEMBER_parent NUMBER(2) DEFAULT NULL);
INSERT ALL
INTO test_A VALUES (1, 'mem1', NULL)
INTO test_A VALUES (2, 'mem2', NULL)

As the actual data is huge, I need to know the best (least expensive) way to select each parent and then all its direct child ordered by member_id the output should look like:
1mem1(null)
4mem41
5mem51
6mem61
2mem2(null)
7mem72
8mem82
10mem102
3mem3(null)
9mem93
11mem113
if when you are querying a table in 11g and you use the order by clause and there is more than one occurrences with the same values in the order by, if the 11g default is different than from 10g.
For instance.
DECLARE MHBulk CURSOR FOR select invoice_nbr, customer_nbr, post_century, post_yymmdd, from CUSTOMERS where customer_nbr = 1234 order by post_century, post_yymmdd;
If you have more than one occurrence of the same customer_nbr, post_century, and post_yymmdd
it looks like the default order for how 11g retrieves the records is a bit different than the 10g default.
currently i m going through some dumps for my OCA-11g prep.I came across one sentence :A view cannot have an ORDER BY clause in the SELECT statement.well this statement is false and the explanation given was :
Query operations containing ORDER BY clause are also permitted, so long as the ORDER BY clause appears outside the parentheses.
The following is an example of what I mean: CREATE VIEW my_view AS (SELECT*FROM emp) ORDER BYempno.
but when i tried running the query like this :CREATE VIEW my_view AS SELECT*FROM emp ORDER BYempno ,it worked w/o giving parentheses.
I Want to make a query to select finished goods product in sales having product code greater than 280 but i have face a problem that order by is not working because products column have character code as well as number. how to sort that column.

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.
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

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??
Which step in the following plan is the first step of execution
I reckon it is "TABLE ACCESS BY INDEX ROWID| BANK_BATCH_STATE"
Is that correct?
In the "Predicate Information (identified by operation id):"
section the predicates - access and filter for the step "TABLE ACCESS FULL | PYMNT_DUES" are displayed first
Isn't there any relation between the order of execution steps and the order in which predicates are displayed?

i want the 10 most recent mission date from mission table . i have tried using rownum but could not get it. TOP does not work
select * from
(select length(code_name) leng from missions
where length(code_name) >7
order by mission_date)
where rownum = 10
;
this does not work ::: no rows are selected and i do rownum = 1 then gives me one record and when i do rownum>=1 gives me all records
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:
FOOTBALL PLAYERS < ID, NAME, ATTRIBUTE>
100-JIM-TALL
101-BOB-STRONG
102-MARK-SMART

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.

I want to remove repeated rows
i have a select query with four table its generating around 650 rows. and i need to update these 650 rows only.
for example
update ps_po_lining b
set y.recv_req = 'N'
where recv_req in
[Code]....
this query runs but its updating 6000 rows. which is not right. we need to update what ever the select query is retrieving.
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
