Performance Tuning :: OWB Mapping - Cube Load
Apr 27, 2012I have a OWB mapping which takes input from a staging table and add those row to the Cube. The underlying table behind cube is a relational fact table joined with the dimensions using foreign keys. Explain plan behind the query has a rather high cost and the mapping runs for 30 minutes. If you see below, in step 17, the cost goes up to 1,396,573 which is also where nested loops start to appear. Query plan is also attached in the image format.

SQL & PL/SQL :: Rollup And Sorting
Jul 2, 2012I have the following query
SQL>
SQL> SELECT DECODE(act.statement_flag, NULL, 'Total',act.statement_flag) "Monthly Statement?",
2 COUNT(account_id) "Count",
3 ROUND(((COUNT(account_id)/
(SELECT COUNT(account_id) FROM accounts
WHERE account_status_id = consts$.acct_sts_active))* 100),2) || '%' "Percent of Active Accounts"
4 FROM accounts act
5 WHERE act.account_status_id = consts$.ACCT_STS_active
6 GROUP BY ROLLUP(act.statement_flag)
SQL> /
Monthly Statement? Count Percent of Active Accounts
------------------ ---------- -----------------------------------------
N 1892 98.08%
Y 37 1.92%
Total 1929 100%
I want the output to be in the following fashion:
Monthly Statement? Count Percent of Active Accounts
------------------ ---------- -----------------------------------------
Y 37 1.92%
N 1892 98.08%
Total 1929
And I would also like to know is there another way to find the Percent of Active accounts in the query.
PL/SQL :: Rollup Grand Total?
Aug 8, 2013I am trying to use rollup for a total, but it doesn't work because what I'm totaling is too conditional. I even tried adding on the totals to the end using a union and a specialized function, but for some reason, the order by stops working when I do the union (all field aliases and types are the same).I know the structure of the query itself probably isn't the best, how I can get the grand total, The subtotals from the rollup work fine, though.
The order by query runs fine against both parts of the union when they are run individually, but once I make it part of the union - the first part of the order by is an unknown field and the second is not a SELECTed list expression. I've commented out the union here. The statement works fine without it except for the grand total being all 0s. I kind of understand why it's all 0s, but not how to get around that.This is running in Oracle 10g2. I am trying to get totals for decisions by each of the four component values: ex_land, ex_imp,tx_land,tx_imp and then subtotals for each component values.
That works for the following query, but I cannot get a grand total through the rollup.
CREATE TABLE "FL_APP" ( "APP_ID" NUMBER(*,0), "FL_STAT_CODE" VARCHAR2(20 BYTE), CONSTRAINT "FL_APP PK" PRIMARY KEY ("APP_ID") ENABLE, CONSTRAINT "FL_APP_FL_STAT_DIM_FK1" FOREIGN KEY ("FL_STAT_CODE") REFERENCES "FL"."FL_STAT_DIM" ("FL_STAT_CODE") ON DELETE CASCADE ENABLE ) ;CREATE TABLE "FL_APP_PROP" ( "APP_ID" NUMBER(*,0), "FL_DECISION_CODE" VARCHAR2(10

SQL & PL/SQL :: Using Decode Function With Group By Rollup?
Oct 18, 2010I am trying to use decode funtion with GROUP BY ROLLUP.
MY query is working fine when i use this two queris individually
SELECT SUM(SAL),DEPTNO,JOB FROM EMP GROUP BY ROLLUP ((DEPTNO),(DEPTNO,JOB));
SELECT SUM(SAL),DEPTNO,JOB FROM EMP GROUP BY ROLLUP((JOB),(DEPTNO,JOB));
But when i use Decode funtion so that i can combine above two scenarios it is not working
SELECT SUM(SAL),DEPTNO,JOB FROM EMP GROUP BY ROLLUP ( DECODE(:A,'S',((DEPTNO),(DEPTNO,JOB) ),((JOB),(DEPTNO,JOB) ) ) )

SQL & PL/SQL :: ORA-00923 - Difference Between 9i And 10g
Aug 25, 2010I 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

ORA-00923: FROM keyword not found where expected
In 10g
SELECT 1,nameFROM nametab where rownum < 2

PL/SQL :: Difference Between Oracle DB 11.2.0.1.0 And 11.2.0.3.0?
Dec 18, 2012When 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?

View 2 Replies View RelatedSQL & PL/SQL :: Difference Between Procedure And Function
May 22, 2010I 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?
SQL & PL/SQL :: How To Get Difference Between Two Rows Of Same Column
Aug 3, 2013Calculating 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
