Aug 17, 2010I am trying one simple operation on Oracle9i DB. I am exporting a table data and trying to import it back. The triggers associated with the insert operation for this table are not being fired during import. Here is the commandline i am using to achieve the same.
1) Exporting the table data.
$ORACLE_HOME/bin/exp SMS_60/SMS_60 file=callfwd.dmp tables=callFwd_customerList TRIGGERS=Y
2) Importing the same data.
$ORACLE_HOME/bin/imp SMS_60/SMS_60 file=callfwd.dmp tables=callFwd_customerList ignore=Y
Import ends with success with all the rows imported in the table but the triggers associated to this "insert" operation.

Jul 1, 2011I have 2 sets of phone number ranges and need to find the ranges that intersect.
create table rng1
(
rng_start varchar2(10),
rng_end varchar2(10)
);
[code]....
When I try to find the ranges matching (intersecting) a certain range (e.g. '21112'-'2111299999'), optimizer does a FULL TABLE SCAN, which is not opimal in my opinion. I use the hint to force the optimizer use the indexes.
select /*+ index_combine(rng2 x_rng2_start, x_rng2_end) */ *
from rng2
where
rng2.rng_start <= '2111999999'
and rng2.rng_end >= '2111';
Plan
SELECT STATEMENT ALL_ROWSCost: 60 Bytes: 17,344 Cardinality: 1,084
7 TABLE ACCESS BY INDEX ROWID TABLE LUMAMIPA.RNG2 Cost: 60 Bytes: 17,344 Cardinality: 1,084
6 BITMAP CONVERSION TO ROWIDS
5 BITMAP AND
2 BITMAP MERGE
1 BITMAP INDEX RANGE SCAN INDEX (BITMAP) LUMAMIPA.X_RNG2_START
4 BITMAP MERGE
3 BITMAP INDEX RANGE SCAN INDEX (BITMAP) LUMAMIPA.X_RNG2_END
However, when I try to join the 2 sets of ranges by matching the intersecting ranges, then the range scan and "BITMAP AND" of the 2 indexes is not done, even though the hint is specified:
select /*+ index_combine(rng2 x_rng2_start, x_rng2_end) */
count(*) cnt
from rng1
join rng2 on
rng1.rng_start <= rng2.rng_end
and rng1.rng_end >= rng2.rng_start;
[code]...
How to make the optimizer use the range scan of both indexes? Is there a better way to match the ranges?
Bitmap Index Not Getting Used
Oct 20, 2012I am using ORACLE 11gR1.
I was running a test on a huge table with a bitmap index on one of the columns. But bitmap index is not getting used. Below are the test details.
create table test (col1 number, col2 number);
begin
for i in 1..1000000
loop
if mod(i,2) = 0 then
insert into test values(i, 'Y');
else
insert into test values(i, 'N');
end if;
end loop;
end;
COMMIT;
The intention here is to have only two distinct values in the entire table. Based on these values I will not build BITMAP index on col2.
CREATE BITMAP INDEX BITMAP_TEST on TEST(col2) COMPUTE STATISTICS;
Now when I run the below query, it doesn't uses BITMAP index. Instead the explain plan shows a full table scan.
select * from test where col2 = 'Y';
Now when I force ORACLE to use index through hint, the cost is too high while using the bitmap index(probably why the ORACLE chose not to use the index at the first stage).
I have read somewhere, that BITMAP index is useful when we have more than 1 or 2 bitmap indexes on other columns of the same table as well And the query should be like
select * from table where col1 = 'Y' and sex = 'F';
In this case oracle will use BITMAP but not in the case where there is only one column that has BITMAP index.
Considering all the factors stated above, is there any way I can fine tune my original query?
select * from test where col2 = 'Y';
SQL & PL/SQL :: Bitmap Or B-Tree Index?
Apr 9, 2010I was executing following query and it was taking about 20 sec's to execute before i decided to create B-Tree(Normal) index on column DeliVery.
Select
DeliVery,Code,Sum(Units),Sum(Loads),Count(units),
Count(Loads)
Where
[code]...
After creating B-Tree index on Column Delivery the execution time has been reduced to one second ,thats what i wanted. But If i create Bitmap index on the same column then execution time is not getting reduced and is still same around 20 sec.I think theoratically "Delivery" column is the right candidate for Bitmap index? whether should i create bitmap index or stick with B-Tree index?

SQL & PL/SQL :: Which Constraint For Bitmap Join Indexes
Jul 18, 2013I have a few dimension tables with surrogate keys and a fact table with foreign keys on columns referring to the dimension table. I want to create primary keys on the dimension tables and foreign keys on the fact table, but with minimal overhead of constraint validation when loading the data.
Other than bitmap indexes on the FK columns on the fact table, I also want to create a bitmap join index on the fact table joined to the dimension table on a handful of dimension columns.
Which is the best suited constraint definition? Only RELY, or RELY + DISABLE, or RELY + DISABLE + NOVALIDATE, or RELY + NOVALIDATE, or any other?

PL/SQL Release 11.1.0.6.0 - Production

I have a procedure that is run weekly to load the data, for which it calls another procedure. This weekly procedure, disables the index, load the data, and rebuilds the index. During rebuilding of index, its giving ORA-00054: resource busy and acquire with NOWAIT error. I dont have privileges to look for session id, and kill the session. How to avoid this error.
create or replace

As you can see, after the procedure wc_upload, COMMIT is issued, and then the rebuilding of the index is starting. So dont know what is causing the table to lock.

Select Statement Gives Different Results Using Bitmap Or Normal Index
Jan 10, 2012we have a strange symptom in a database Oracle 11.2.0.2 EE. Following question comes from our application developers.
The following SQL statement:
SELECT
v.reporting_month,
sum(v.f_s) "REV_S",
sum(v.f_f) "REV_F",
sum(v.f_c) "REV_C",
[code].......
gives different result when we exchange the index ksr_valid_until_i on table kreditkarten_sets_rs. For some reasons we changed the index from bitmap to normal and are getting different results. Switching back gives us the same results as before. When we avoid the usage of this index in the statement than we are getting the same results as when we are using the normal index.

Forms :: Distribute Master Block Total Amount In Detail Block Line Wise
May 5, 2012i have a master detail form, In Master block we have one field cheque amount and in Detail block we have field receiveable amount invoice wise. if company paid us a cheque amount we will enter this amount in Master block field Cheque amount and in detail block there will be invoice wise receivable amounts. i want to distribute the cheque amount in detail block invoice wise for example
Cheque amount in master block = 291
Invoice wise receiveable amount is as follows
Invoice No , receivable amount , Received amount
10, 196 , 0
20 , 95 , 0
30 , 54 , 0
Result should be as follows:
Invoice No , receivable amount , Received amount
10, 196, 196
20 , 95 , 95
30 , 54, 0
Received amount field should be distributed according to the receivable amount when recevied amount = cheque amount then remaining will be 0.

PL/SQL :: Bitmap Index On Number Column X Char Column?
Jul 23, 2013is there some performance/access difference between a bitmap index on a number column and char(1) column? Both columns are not null with a default value.My application has a querie like this:
select ass.column20, ass.column30from table_a pucinner join table_b asson ass.column1 = puc.column1where pc.column_char = 'S'and ass.column_char02 = 'P'
If I create a bitmap index on column "column_char", the access plan is not changed. But changing the column datatype to number(1) and obviously the values, the index is accessed and the cost decreases.This table has 4.000.000 rows. Oracle 11.2.0.2SO
