1. difference between v$sql and dba_hist_sqlstat?
2. as of i have understood, dba_hist_sqlstat gets refreshed from v$sql.
if i run this below query i get different outputs.. how?
by using v$sql table
WITH t AS
(SELECT force_matching_signature ,
SUM(executions_delta) executions,
COUNT(*) cnt ,
parsing_schema_name ,
MIN(MODILE1) MODULE1
[code].......
Detail table will look like below:
Product_id issue_date action_date Force_date
1 10/10/2012 10/10/2012 10/10/2012
2 10/10/2012 10/10/2012 10/10/2012
3 10/10/2012 13/10/2012 15/10/2012
[code]....
Need the data like
Issue_date count_action_date count_Force_date (diff(action_date,force_date) 1 2 3 4 5 6(days since over)
10/10/2012 3 4 1 4 2 1 0 0
How to get the data like this? automatically how to get 123.... and how to calculate the difference by which day the count of difference is going?
How do I get the max difference where each value can look at only the next value(ordered by date asc) on any particular day
example first row on 20090902 is 501.25 (earliest date)
756.2 - 501.25
4735.83 - 501.25
35.83 - 501.25
[code]....
How one can get date difference in days between two dates in Oracle reports ?

I encountered this problem when we recently migrated to 10g. The table nametab has two columns roll(number datatype) and name(varchar2(10) datatype).Following are the queries used and I have deliberately not given space between the "select" clause and the "from" clause.
In 9i
SELECT name,1FROM nametab where rownum < 2
NAME 1
---------- ----------
Bharath 1
Same query in 10g
SELECT name,1FROM nametab where rownum < 2
ORA-00923: FROM keyword not found where expected
Here, I have interchanged the select columns.
In 9i
SELECT 1,nameFROM nametab where rownum < 2
ORA-00923: FROM keyword not found where expected
In 10g
SELECT 1,nameFROM nametab where rownum < 2
ORA-00923: FROM keyword not found where expected
what are difference in between oracle 9i and 10g regarding with Sql queries?
View 1 Replies View RelatedI am looking for an explanation for having the following query:
SELECT PK_SERIAL_NUMBER FROM TABLE1 MINUS (SELECT FK_SERIAL_NUMBER FROM TABLE2);
Which normally returns the values of SERIAL_NUMBER that are not passed to the child table TABLE2
and the query:
SELECT PK_SERIAL_NUMBER FROM TABLE1 WHERE PK_SERIAL_NUMBER
NOT IN
(
SELECT FK_SERIAL_NUMBER FROM TABLE2
);
which returns 0 rows!
I listen that there is a big diff B/W indexing in oracle 8i and oracle 11g.
what way the indexing is different B/W 8i and 11g.

AS_ON_DT DATE not null,
EXP_ID NUMBER(10) not null,
BO_REF_ID VARCHAR2(30),
FO_REF_ID VARCHAR2(30),

BK_INV_TYPE_ID VARCHAR2(20),

When I use this sql: CREATE USER testuser IDENTIFIED BY "welcome1 " to create user in Oracle DB 11.2.0.1.0. I can login with testuser/welcome1, please notice the welcome1 is not end of black space in login.
But when I do the same thing in Oracle DB 11.2.0.3.0. I can't use this user login with any password. I tried welcome1, "welcome1 " but all failed.
Why there are this difference between 11.2.0.1.0 and 11.2.0.3.0, and since in 11.2.0.3.0 the create sql are success, what password is correct when login?

i want to know is there any difference between upgradation of SID and database. while upgrading my database from oracle 11.2.0.2 to 11.2.0.3 in DBUA it shows my SID is upgrading (ORCL) but i have few other databases ex (test and prod).
is it enough if we upgrade the SID or we must perform any other actions..

View 2 Replies View RelatedI know difference between procedure and function.if we want a return value from procedure, we can have OUT parameter. Similarly with function, in addition to returning a value from function, it can also send an OUT parameter value as a return value. That means, in one or the other way we are able to get a return value from both program units. Normally, I would fill a OUT variable with error message when an exception occurs. I use this varaible,after procedure call, to detect if an exception occurred or not. Similar task can be performed by a function, it returns a true/false and a value thru OUT variables.
both program units return values in the form of OUT parameters. Where exactly should we use a function, where exactly should we use a procedure?
Calculating the difference between the two rows of same columns? Example of my Scenario is as follows
I have a table as shown below, there are checks thats has been issued per week (to tell how its been issued per week ,if you see the week number ,there is a change in week no for period of 7 days i.e. what i have to show on my results tables based on week no and probably we may need to take into account for check no too.)
wekno ! checkno ! end date
------ ! ------ ! ------
1 ! 1 ! 1/7/2012
1 ! 2 ! 1/8/2012
1 ! 3 !1/9/2012
2 ! 1 ! 1/14/2012
2 ! 2 ! 1/15/2012
3 ! 1 ! 1/21/2012
result table and date range i picked up was 1/1/2012-1/31/2012
wekno ! checkno ! end date ! previous period ! Daysin period
------ ! ------ ! ------ ! ------------- ! ------------
1 ! 1 ! 1/7/2012 ! null (as previous period is 2011 and so prvs year i dont count) ! 7 this because we see change in wkno per 7 days
1 ! 2 ! 1/8/2012 !null becoz this one falls same week and therefore previous peroid would be the same as above ! 7 above reason
1 ! 3 ! 1/9/2012 ! null becoz this one falls same week and therefore previous peroid would be the same as above ! 7 above reason
2 ! 1 ! 1/14/2012 ! 1/7/2012 becoz this a second week as you see the change in wekno and therefore its previosu period is 1/7/2012 ! 7 above reason
2 ! 2 ! 1/15/2012 ! 1/7/2012 becoz this check falls on the same second week so previosu would be 1/7/2012 ! 7 above reason
3 ! 1 ! 1/21/2012 ! 1/14/2012 as a new week no starts this gonn be 1/4/2012 ! 7 above reason
