PL/SQL :: To Create Function Based Index For Group Function Columns
Jun 15, 2012Is anyway to create function based index for group function columns.
For example
select max(timestamp),min(age),averge(sal).... ... .. from tab;

Create A Function Based Index On Bold Highlighted
Jul 2, 2010Using oracle 10g R2 on sun-solaris 10 (sparc-64) Well in the MIS system we have lot of ad-hoc queries coming up. We have proper indexing. Say an example which runs very slow;
SELECT GLKCO, GLDCT, GLDOC, GLDGJ, GLJELN, GLEXTL, GLPOST, GLICU, GLICUT, GLDICJ, GLDSYJ,
GLTICU, GLCO, GLANI, GLAM, GLAID, GLMCU, GLOBJ, GLSUB, GLSBL, GLSBLT, GLLT, GLPN, GLCTRY, GLFY, GLFQ,GLCRCD, GLCRR, GLHCRR, GLHDGJ, GLAA, GLU, GLUM, GLGLC, GLRE, GLEXA, GLEXR, GLUPMJ, GLUPMT, GLBCRC, GLCRRM, GLACR, GLAN8
FROM "PRODDTA"."F0911"
WHERE GLUPMJ <> 0
AND TO_DATE('1 JAN' || (19+substr( GLUPMJ , 1, 1)) || substr( GLUPMJ ,2,2)) + substr( GLUPMJ , 4, 3 ) -1 BETWEEN SYSDATE - 365 AND SYSDATE
[code]....
Here GLUPMJ already indexed so the second query returing an index scan but the first query does a FTS naturally.Now even if I plan to create a function based index on 'the bold highlighted' but how.
create index glupmj_idx on f0911(TO_DATE('1 JAN' || (19+substr( GLUPMJ , 1, 1)) || substr( GLUPMJ ,2,2)) + substr( GLUPMJ , 4, 3 ));..Error If I don't use a FBI my query will result in FTS.
1> how to create a FBI here in this case
2> In MIS systems where 'n' no of ad-hoc queries can come up, how to avoid FTS.
Unique Function Based Index
Jun 27, 2011I have a table which sees a lot of use for queries
CREATE TABLE CASE_STAGE
(
ID NUMBER(9) NOT NULL,
STAGE_ID NUMBER(9) NOT NULL,
CASE_PHASE_ID NUMBER(9) NOT NULL,
"CURRENT" NUMBER(1) NOT NULL,
--and other columns
)
ID is a primary key
CASE_PHASE_ID is a foreign key
"CURRENT" should only ever have values of 0 or 1. When it has a value of 1 it is unique for that CASE_PHASE_ID
What I have tried that doesn't work is
create unique index case_stage_F_IDX1 on case_stage("CURRENT", case_Phase_id) which gives me
ORA-01452: cannot CREATE UNIQUE INDEX; duplicate keys found
What is the correct syntax, something like ("CURRENT"=1,case_phase_id) seems right but fails with an error about a missing bracket. Do I need to use a CASE statement here?
Function Based Index With Trim
Jun 22, 2011I have created a function based index(FBI) with trim(header_date), but when i query the table by passing the hardcoded date, it is not working and i have to manually apply trim to get the result?
my query after applying FBI is
select * from abc where header_date = '21-JUN-11', no results are returned and when i apply trim to header_date it works fine .
Performance Tuning :: Function Based Index Is Not Being Used
Feb 22, 2012I have a table which has 4M records
This table has a query where one of the condition is
AND STATUS <> 'C'
Now the data is as following
select count(*) record_count, status from new_business group by status;
record_countstatus
4298025C
15N
13Q
122S
I want to know if following index would be useful in this case while the condition in where clause is
"AND STATUS <> 'C'"
create index nb_index_1 on new_business(case when status in('N','Q','S') then 1 else NULL end);
Or
create index nb_index_1 on new_business(case when status ='N' then 'N' when status='Q' then 'Q' when status='S' then 'S' else NULL end);
I tried it on a sample table but the index is simply not picked up even when hinted following are the db level settings
query_rewrite_enabled string TRUE
query_rewrite_integrity string enforced
I tried it 'query_rewrite_integrity' with 'trusted' as well .
Query Not Picking Function Based Index
Apr 3, 2012One of our query is not using function based index, the required priv is granted to the user executing the query and also tables stats are gathered? what could be the reason for the query to not to pick the FBIndx? the table is a huge one having million of records, is it that CBO thinks that not picking FB indx is the best execution plan? let me know how can we make the query use the FB indx, also there is a restriction that we cannot force it using hints.

Server Administration :: Possible To Run SHRINK SPACE Against Table With Function Based Index
Jun 27, 2013It is not possible to run SHRINK SPACE against a table with a function based index. This is documented, and I've tested on the current release. I've reverse engineered it a bit, and the issue is in fact that you cannot SHRINK SPACE if there is an index on a virtual column:SQL> SQL> create table t1(c1 number, c2 as (c1*2)) segment creation immediate;
Table created.
SQL> alter table t1 enable row movement;
Table altered.

SQL & PL/SQL :: Analytic Function To Get Count Based On Special Criteria?
Nov 4, 2010I have the following query with analytic function but wrong results on the last column COUNT.
1)I am getting the output order by b.sequence_no column . This is a must.
2)COUNT Column :
I don't want the total count based on thor column hence there is no point in grouping by that column. The actual requirement to achieve COUNT is:
2a -If in the next row, if either the THOR and LOC combination changes to a new value, then COUNT=1
(In other words, if it is different from the following row)
2b-If the values of THOR and LOC repeats in the following row, then the count should be the total of all those same value rows until the rows become different.
(In this case 2b-WHERE THE ROWS ARE SAME- also I only want to show these same rows only once. This is shown in the "MY REQUIRED OUTPUT) .
My present query:
select r.name REGION ,
p.name PT,
do.name DELOFF,
ro.name ROUTE,
[code]...
My incorrect output[PART OF DATA]:Quote:
REGIONPT DELOFF ROUTE THOR LOC SEQ COUNT
NAASNAAS MAYNOOTHMAYNOOTHR010 DUBLINRD CEL 1 1
NAASNAAS MAYNOOTHMAYNOOTHR010 NEWTOWNRD CEL 2 1
[code]...
My required output[PART OF DATA]-:Quote:
REGIONPT DELOFF ROUTE THOR LOC COUNT
NAASNAAS MAYNOOTHMAYNOOTHR010 DUBLINRD CEL 1
NAASNAAS MAYNOOTHMAYNOOTHR010 NEWTOWNRD CEL 1
NAASNAAS MAYNOOTHMAYNOOTHR010 PRIMHILL CEL 1
[code]...
NOTE :Count as 1 is correctly coming.But where there is same rows and I want to take the total count on them, I am not getting.

Apr 15, 2010i have a project that needs to have a identity number in the table.this is the table:
create global temporary table BOOK_INFO
( row_id number(5),
BOOK_TITLE char(20),
BOOK_AUTHOR char(15)
) on commit preserve rows;
i dont know how can i generate row_id, in sybase i can only set the datatype of row_id in IDENTITY and it will automatically generates number and as the transaction ended the row_id will automatically back to 1.
in oracle i tried to create sequence but it didnt back to 1 when the transaction/procedure ended.. Like for example if the procedure ended and the last row_id inserted in the table is 300 the next run of the procedure will start in 301. but i need to start in 1 in every run of the procedure.
Also, i tried to set the variable v_row_id to 0 and it increment by 1 as it insert in the table, but the problem is there are times that in 1 book_title there is more than 1 author. so the v_row_id of the book_title with more than 1 author is all the same.Here is my query:
insert into BOOK_INFO
(select v_row_id, BOOK_TITLE, BOOK_AUTHOR from LIBRARY);
The result is:
ROW_ID BOOK_TITLE BOOK_AUTHOR
1 BOOK_1 AUTHOR_1
1 BOOK_1 AUTHOR_2
1 BOOK_1 AUTHOR_3
1 BOOK_1 AUTHOR_4
2 BOOK_2 AUTHOR_5
SQL & PL/SQL :: Create A Function Which Can Be Used In A Select Query?
Jun 11, 2008I have a table structure like :-
Create table test(A varchar2(50),B NUMBER);
The data in that table is like that:-
A B
----------------------
2*3
2*4*5
4*5
column B contain no data.
I want to create a function which can be used in a select query,and the output should come like that :-
A B
----------------------
2*3 6
2*4*5 40
4*5 20
Means column B contains the resultant value of column A.And the above output should come through a select statement.You can use any function inside the select statement.
