, (SELECT PAY.PAYMENTCODE FROM M_ECS_PAYMENT_MODE PAY WHERE TO_CHAR(PAY.ID) = BANK.ECS_FACTORING_HOUSE) AS
[code].....
i have used composite index below column which used in the tbl_bank_statement table.like column name tbl_bank_ statement (policy_ no,ecs_ micr_code,ecs_factoring_house,ecs_mandate_status)

Let's consider such table that all rows fit into single block:
SQL> create table test as select rownum id, '$'||rownum name from dual connect by level <= 530;
Table created.
SQL> create index i_test on test(id);
Index created.
SQL>
SQL> begin
[code].....
why does approach with full scan take longer even if table occupies only one data block? PS. 11gR2

I want to get clear with one thing yesterday i installed oracle9i and dev 2000 to my client.
when they run one report they got stuck with pl/sql compilation errorrep-1247
when i checked that report in the report builder, in the query they are using some other table which is not belongs to that schema,then I give that schema.tablename and compiled, but this is coming for other reports also, then only i came to know that they are acceessin other schema also, how can i sort this out.
can i fix this by givin full access privilige or what privilige can i give to get full access of other schema table.
how can i check in the old database what are all the roles and privileges given to this user,

I�m Using Oracle 11.I have a table with 16 million rows and an index (let's call it the employee table with an index on department). I need to select all the employees whose departments are located in the uk. I achieve this by selecting all the department numbers from departments where location = 'UK' in a sub select then plug this into the main query as follows:
SELECT *
FROM employees
WHERE department IN (SELECT department from departments where location = 'UK');
It takes ages, 25 seconds or more, the explain plan shows its doing a full table scan on emplyees. I need it to use the index. The sub query is instant and returns only 5 rows. If I explicitly put the 5 numbers in the IN clause the query uses the index and executes in 0.04 seconds. See below:
SELECT *
FROM employees
WHERE department IN (1,2,3,4,5);
I need it to use the subquery once and then use the index on the main table.

We have an old full export .dmp file from a 10g db and there are 451 records in one specific table that we need to export. Is it possible to IMP just the one specific table from a full dump? Or, another option, can we extract the records from the one table in the .dmp file into an xml file?

We have a large table of equally sized data blobs in our Oracle system and we'd like to select the whole table once into the memory. The corresponding tablespace is stored in SSD fast disks and is managed by ASM. However the achievable select speed (reading data into memory) of Oracle is not satisfactory. When we store the data in SSD disk using custom methods (e.g. in SQLite DB files) and load then into memory by multithreading (8 thread) techniques, the speed is more than 15 times that of Oracle.
Is there any way to optimize the oracle and ASM for increased full table select in our case. We tried FULL TABLE SCAN and PARALLEL hints and DB_FILE_MULTIBLOCK_READ_COUNT too, but with no success.
FYI:Our data blob is about 4.2kB and each DB_BLOCK_SIZE is 8kB. The ASM segment is configured for AUTO-ALLOCATE. The table is partitioned by HASH. Our oracle system is not RAC.

I am doing an export using the following parfile information:
userid=/
directory=datapump_nightly_export
dumpfile=test_expdp.dmp
logfile=test_expdp.log
full=y
content=all
However when I run this I do not see the sys.aud$ in the log file. I know I can do a seperate export to specifically get the sys.aud$ table but is there any way to include it in with my full export?

Below query is degrading the performance of database. As we know that, without where clause, query do full table scan.Now, it is written to generate the sequence no.

When I invoke SOAP Web-Service using APEX_WEB_SERVICE.MAKE_REQUEST, then I'm able to get response from web-service. However all German character are replaced by JUNK data. However data is coming fine when I test web-services using SOAP UI.
I tried to invoke web-service using UTL_HTTP. However when I use UTL_HTTP, then I'm getting following error.
ORA-24247: network access denied by access control list
<li> Why German characters are replaced by Junk data while invoking web-service from APEX, while it's working fine from SOAP UI

I am using Oracle9i Enterprise Edition Release 9.2.0.6.0 - 64bit Production.I have a table D_GEOGRAPHY_25729 in RDS schema and I have created a role ACC_D_TABLES logging as ADMIN.
Now I have given GRANT SELECT access for table D_GEOGRAPHY_25729 to role ACC_D_TABLES.
There is another schema TRANS in the same database which has the role ACC_D_TABLES. But after logging in this schema, I am not able to query directly from table D_GEOGRAPHY_25729. I need to use like below to access the table.
select * from RDS.D_GEOGRAPHY_25729 Having the correct role ACC_D_TABLES to TRANS schema, why should I use RDS.D_GEOGRAPHY_25729 ? Is it not possible without prefixing the RDS schema name?
It is possible when I create a public synonym for D_GEOGRAPHY_25729 in RDS schema, but if i do so everyone can access this table.

But TEST2 is used by an application which requires to read view metadata and then sync with application afterwords start reading. Is there any special permission to grant to access metadata of the view / table.

I am trying to access and modify data of a table of another schema which contains 80,000-90,000 records. My procedure is taking near about 30 mins to complete the operation. faster access and updation of table data.
Details:
I have two schema: TEST and PROD
I am running the below code from TEST Schema.
/* CODE START HERE*/
DECLARE
exc_bulk_errors EXCEPTION;
PRAGMA EXCEPTION_INIT (exc_bulk_errors, -24381);
v_block_count NUMBER := 1000;
[Code]....
The above code is taking near about 30mins to process.
I have also tried another approch: Creating a procedure in PROD schema to update COMPONENT_MASTER table and by calling the procedure from above code by passing component code.
/* PROCEDURE CALL FROM ABOCE CODE INTEST SCHEMA*/
PROD.PROCEDURE_TO_UPDATE(v_comp_code);
But still it is taking same time.

Following are 2 queries, which return same results as far as the input parameter is NOT NULL
select /*+ gather_plan_statistics */ * from PX_CJQ where decode(:x,null,1,object_id) = NVL(:x,object_id);
select /*+ gather_plan_statistics */ * from PX_CJQ where object_id = NVL(:x,object_id);
However the execution plan differs a lot The FTS cost or rows accessed count also varies what could be the reason? The PX_CJQ is simply select * from dba_objects and has index on object_id which anyway is not being used in this case

I have a Database that has a frontend in MS Access and a backend in Oracle. When I try to open the Oracle Table/s in the MS Access Frontend, it gives me this error message:
Reserved error (-7711); there is no message for this error.
There is some stuff on the internet about this error but none of it fixes my issue. It seems to be an MS Access error rather than an Oracle error. Only thing is this issue is only on Machines that are running on XP. I have no problem on mine which is Windows 7.
