I have a requirement where i need to replicate the for loop functionality through sql query.In pl/sql i can achieve this through cursors or for loop but is there any way to do or replicate the same functionality in sql queries . For example i want to repeat the operation for set of records or iterate through set of records and fire query accordingly .Is it possible through sql query

i am trying to do something the following .. but I can't get the syntax correctly for the select statement inside the secondary_loop ...

i have query which scores a customer details on some factors and gives it a rank/I have a table called agents which holds the agents details.
This is how i get the rank:
select *
from (
select customer_name ,agent_number
[code]....
The agents table has agent_number and agent_Name....By the above query i check various score against all available agents and assign customers to agents who have highest score or rank is 1
But my problem is who to loop through the process.. i mean after the intial customers are assinged with agents it should run again for remaining customers and for agents who are free(and rank for them is 1) should be checked for assignment Once all agents are assigned but still more customers are available then agents even thoug they are already assigned they can be assigned now since no agent is free..
I'm joinging two tables event_types and tmp_acc tables.
event_types contains 2 Billion records
tmp_acc contains 20,000 records.
Resulting rows are about 300,000 records in event_types table end_t and account_obj_id0 are joined indexed
no indexs in tmp_acc.
When I run below query with nexted loop it takes 6 hrs to complete. But when I run with hash join even after 4 days it was still running. what is wrong with hash join here. Why it takes so long. I'm joining only 20000 rows. So I think there should be a way to get result rows quickly.

View 3 Replies View RelatedI told about Oracle multi master replication below.
Can I replicate some objects of "X" schema at A server to "Y" schema at B server using MM replication?
The document says "Propagators are also useful for distributing replication loads in configurations that involve a master database that must replicate to a large number of subscribers".
Link [URL]........
My question is how do we define this " large number ". Is 5 a large number or 10 a large number ? I've a bidirectional legacy replication scheme wherein a node replicates to 10 other nodes. Should i introduce Propagator between these nodes.
I thought that you are not supposed to be able to assign the value of an out parameter to a variable (Feuerstein, 5th ed) and yet I was just
able to do this without any compilation error messages. Is Feuerstein wrong or am I missing something? Has the functionality changed?

I am having performance issues on a query in a production environment that I cannot replicate in our test environment. Our test environment is an import of production. Version information is:

Misses in library cache during parse: 1
Optimizer mode: ALL_ROWSThis performance problem started a few weeks ago and the problem seems to be in the high number of consistent reads during fetch. The DBA tried restarting the instance and gathering fresh stats on the tables but that has not made a difference. Now he wants to export the tables, drop the schema and re-import.
Earlier I am using oracle 10g (10.2.0.4) and now we are planning to use 11gR2 (11.2.0.1).we are using oracle stream functionality in 10g. I just want to know is there any new feautre available in 11g which replace the stream functionality? we dont want to use stream (in 11g) any more.

View 11 Replies View RelatedI would like to use the below decode in DBMS_OUTPUT in place of cur_rec.data_type. Could I know how can I achieve this.
The DBMS_OUTPUT is inside a loop and output is shown below as an example.
NOT NULL -- EMP_ID NUMBER
,NOT NULL -- EMP_NAME NUMBER
,NOT NULL -- HIRE_DT DATE
,NOT NULL -- SALARY NUMBER
DBMS_OUTPUT STMT:
Dbms_Output.Put_Line(nullable ||CHR(9)||CHR(9)||' -- ' ||upper(cur_rec.column_name)||CHR(9)||CHR(9)||cur_rec.data_type);
STMT to use in place of cur_rec.data_type:
substr(decode( data_type, 'NUMBER', decode( data_precision, NULL, NULL,'('||data_precision||','||data_scale||')' ),data_length),1,11)
Also I am not able to align the output using CHR(9).
