Using 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;
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.
I need to trap user input by checking if the node in my tree is selected (higlighted) or not. When I test using SYSTEM.TRIGGER_NODE_SELECTED, whether I click the node to select (the node is highlighted) OR I click the plus (+) sign to expand the node, the function both retunrs TRUE.
I don't the user to add node when the current node is not selected and highlighted.
I 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?
I 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 .
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
One 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.
It 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> alter table t1 shrink space; Table altered. SQL> create index i1 on t1(c2); Index created.
SQL> alter table t1 shrink space; alter table t1 shrink space
ERROR at line 1: ORA-10631: SHRINK clause should not be specified for this object.
I'm trying to create bold and normal text in the same paragraph with the library PL/PDF, but I can't. This is a small example:, this is an example to the library PL/SQL, adding text in bold and normal text." This text should be justified on the margins I can set.
I have noticed a very questionable phrase on an article updated in 2011: "Oracle SE may allow you to create a function-based index, but you must pay for an EE license to use FBI's." [URL] Is this true? I have tested a FBI on my SE and works just fine.

I have a requirement where the user input values will be passed as comma separated string to backend, which is queried against the table using instr. But the index present on the table is not using the index , due to the instr function.How can I create a index in such a way that The instr function uses it.
The below query is going for full table scan due to this.
select * from test_idx where (INSTR (','||'E10000'||',', ',' || ccn || ',') <> 0 OR 'E10000' = 'DEFAULT') and mod='90396' and rpt_flag='O' and smp_identifier=2
how to recreate the above index so that these queries uses this index.
I 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

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.

Want to take the Start_Date for that year, CREATE A NEW COLUMN and place that START_DATE (which is row 1 for the year (min)) in it. So for ID 1 TERM is 1201 and 1202 BUT we want the top start date (earliest start date) and CREATE a clumn (NEW_START_DATE) and place that date in there wherever year is 2012.

i want to create a bitmap index,but getting the error shown below..i created primary key on column dname of dept and unique constraint on empno of emp.
SQL> create bitmap index bindx on dept d(d.dname) from emp e,dept d where e.deptno=d.deptno; create bitmap index bindx on dept d(d.dname) from emp e,dept d where e.deptno=d.deptno * ERROR at line 1: ORA-25954: missing primary key or unique constraint on dimension
CREATE TABLE test1 (strt_num NUMBER , end_num NUMBER , des VARCHAR2(5), CONSTRAINT pk_strt_num PRIMARY KEY (strt_num) ); INSERT INTO test1 VALUES (5, 8, 'GC'); INSERT INTO test1 VALUES (10, 25, 'AB'); INSERT INTO test1 VALUES (12, 35, 'PC'); INSERT INTO test1 VALUES (22, 65, 'LJ');
SELECT * FROM test1
STRT_NUM END_NUM DES -------------- ------------ ------------- 5 8 GC 10 25 AB 12 35 PC 22 65 LJ
The requirement is the records should be split based on below conditions
1. Split only those records WHERE (end_num - strt_num) > 10 2. If TRUNC((end_num - strt_num)/10) = n, then n + 1 number of rows should be created for that record 3. While splitting the records, -> For first record , START_NUM = Original STRT_NUM and END_NUM = START_NUM + 10 -> Second record , STRT_NUM = previous END_NUM + 1 and END_NUM = previous END_NUM + 10 And this should continue for all records except the last record -> For last record, STRT_NUM = previous END_NUM + 1 AND END_NUM = Original END_NUM
This table has 5 million records. Only for 2000 records (end_num - strt_num) > 10.
Expected Output.
STRT_NUM END_NUM DES ------------- -------- --------- 5 8 GC -- No chage, END_NUM - STRT_NUM < 10
difference between the ways we create Reverse Key Index on the table.The two ways are as below:
1) CREATE INDEX <Index_Name> ON <Table_Name>(<Column_Name) REVERSE ; 2) CREATE INDEX <Index_Name> ON<Table_Name>(REVERSE(<Column_Name>)) ;
Which one is the appropraite one. Are both going to act in the same way.
I created index in both ways one by one on the table.But when I fire the select statement against the same table, The explain plan doesn't show any cost and it shows the full table scan in both ways.The select statement used is as below...I want to compare the column with string RBO(i.e('RBO%') at the start.
SELECT * FROM <Table_Name> WHERE REVERSE (<Column_Name>) LIKE '%OBR' ;
The select statement is giving me the correct result. Only the explain plan is showing Full Table Scan.can we use this reverse with IN operator also in the same way by reversing the values.
I use Oracle 10.0.2.0.1.If I create a table with constraint key; after that I create an unique index key, I got an error. Does it mean when I create a table with constraint the unique index are automatically created and I could not create index key as I did as below?
create table test_const(ename varchar2(50) not null, key_num number not null, descr varchar2(100), constraint constraint_test_const unique (ename, key_num)); create unique index test_const_idx on test_const ( "ENAME","KEY_NUM" ) tablespace tmp_data;

This unselective index scan on step 36 of the explain is returning 14 rows but optimizer is selecting 3064 K rows from the table .
I tried creating combined index on all 3 columns mentioned in the predicates for 35th step , but that is not utilized .
how to index this whole expression ::--
(ACCNT_FLG<>'N' AND (INT_ORG_FLG<>'Y' OR PRTNR_FLG<>'N'))
Something like CREATE INDEX XYZ on table((ACCNT_FLG<>'N' AND (INT_ORG_FLG<>'Y' OR PRTNR_FLG<>'N')) compute statistics ;
Is it a possible to create table using clause below together with index ?
create table the_table as select col1, col2 from table2
I got procedure which create a table in the schema B. The procedure is called from schema A. But when I write into procedure query for create index then I got a error:
ORA-01031: insufficient privileges when ...executing
Therefore I think about to create table together with index.
