Here is my code looks like
FOR i IN (SELECT table_name, sqlstring
FROM table_list) -- returns maximim 30 tables
loop
execute immediate 'update '||i.table_name||' set status=''done'' ';
end loop;
in this all tables are independent, it is a bit slow as update queries are getting executed sequentially. .
where i can execute update statements in parallel.
Is it possible to have multiple variables in a for loop. For expample:
FOR i AND j in 1..10
I was wanting to increase one of the variable more than the other.
tell me the advantages of using more than one redo log thread? Currently i am setup with 3 logfile groups and 3 members in each group.Ie
logfile group 1 ('/u01/oradata/pri/redo01a.dbf',
'/u02/oradata/pri/redo01b.dbf',
'/u03/oradata/pri/redo01c.dbf') size 30M,
group 2 ('/u01/oradata/pri/redo02a.dbf',
'/u02/oradata/pri/redo02b.dbf',
'/u03/oradata/pri/redo02c.dbf' ) size 30M,
group 3 ('/u01/oradata/pri/redo03a.dbf',
'/u02/oradata/pri/redo03b.dbf',
'/u03/oradata/pri/redo03c.dbf' ) size 30M
i have a procedure which outputs 10 refcursors. It is called called by a .NET utility which then writes the data to 18 different flat files. The proc is of below format
CREATE OR REPLACE PROCEDURE FILE_EXTRACT
(OUTREC1 OUT SYS_REFCURSOR,
OUTREC2 OUT SYS_REFCURSOR,)
AS
BEGIN
OPEN OUTREC1 FOR
SELECT /*+PARALLEL(A,8)*/
COL1,COL2
FROM TABLE A;

I have used parallel hint because all the tables used in the queries a huge tables and this is a nightly batch job. The issue here is that i have expected oracle to use 8 processes for this execution so all my select statements have parallel hint with degree 8 , but unusaully the procedure is erroring out on production databases because of maximum number of connections are being spawned and the database is not able to create any new session. When i debuged and did a quick test proc where i used only one out refcursor it ran only 9 threads . then i ran by adding one more out ref cursor it spawn 17 threads. I think its the way .NET is fetching data from each of these cursors.When i print the first refcursor i do see queries which are running for the second along with the first causing the parallel queries run more than expected. The cause of the problem here is all the refcursors are executed and waiting to return data. SO when .net starts reading first cursor the other queries also run.

I have a list of strings ( like a,b ,c) that I want to loop againts. I will be creating string to execute them as dynamic sql.I could have put the string in a table and loop againt the table but this is a deployment script so I do not want to create any table.I can also do
DECLARE
cursor c is SELECT 'a' FROM dual UNION SELECT 'b' FROM dual ;
BEGIN
for i in c
loop
.......
end loop.
END;
But I have many strings to loop over. What is the best way to achieve it. Can i use collection to achieve this?
I have a table which I will call 'fruit basket' which contains the following data:
basket_ref, fruit, fruit_serial
1, apple, 1
1, banana, 2
1, pear, 3
2, apple, 1
2, lemon, 2
What I want to produce is a table in the following format
basket_ref, all_fruit
1, apple banana pear
2, apple lemon
There could theoretically be any amount of fruit in a given basket, so I will need to set up some kind of loop in order to read each record from the original table. I am not sure how it would be best to do this.
I have a cursor which I am opening and then looping through. Within this loop I am comparing attributes within this cursor with attributes from another loop that this one is within.
you will see in the IF statements (there are several distinct IF statements within the loop) that there is a check which assesses if the attributes are not equal.
If they are NOT, the value of v_mismatch is set to 1
What I need to do instead of setting this to 1, is to go to the next record in the loop. How can I achieve this?

This query that I pasted is working correctly.Let's say a case has 4 owners, it finds me the first owner and show me its address.
However, I want to execute this query for all owners so it should jump the previous owner it found. Lets say for that example that the loop ends at 4.
How may I fix this problem so that the loop do not return always the first owner but it keeps getting 1,2,3,4...also I should increase the sequence value for each situation

I am an experienced SAS programmer jumping into PL/SQL for the first time and have already encountered a problem.Let's assume I have 7 records (shown below). (In reality, I have millions of records, but the concept's the same.) The Value field is only populated when it changes. Therefore, I am forced to "fill in the gaps" as I read the data file. It's fairly straightforward. I carry the value foward one record at a time, using it if the Value field in not populated. The ANSWER I want is also shown.
In reading through a PL/SQL book, I realized that only 2 chapters are relevant to what I do. My guess is this solution involves cursors; probably a Cursor FOR loop,

While Condition
LOOP
BEGIN
Insert into table1 values(......);
[Code]...
EXCEPTION
When OTHERS THEN <capture the error while inserting into an Error table>
END;
END LOOP;

Now I want that If one of the insert statement within the loop fails (say table2) the exception should be captured and next insert statement (table3) should be executed.
How can I do this ? I guess I wont even need a loop

I have a cursor returning some value.
for each value returned by the cursor i need to traverse through 31 rows(1 row per day * no of days in the month).
E.g. if cursor returns service_name as xyz then for xyz there can be 31 rows(service may not be used on some days)
I need to go to all of them and take some values and move them to a flat file. how should that be done?

a project I'm working on. I normally work in SQL Server, so I'm a little stuck on this one.
I have a temp table (tmp_stack) with four columns:
Floor [varchar]
Unit [varchar]
Block [number]
BlockStart [number]
BlockEnd [number]
BlockStart and BlockEnd are currently NULL. What I need to do is loop through the table for each Floor and update BlockStart and BlockEnd for each Unit depending on how many blocks they use and how many have been used by prior units on that floor.
For example:
There are three units on Floor #1: 1A, 1B, and 1C.
1A = 5 blocks
1B = 3 blocks
1C = 2 blocks
For 1A, BlockStart should = 1 and BlockEnd should = 5
For 1B, BlockStart should = 6 and BlockEnd should = 8
For 1C, BlockStart should = 9 and BlockEnd should = 10
And everything should reset back to the beginning on successive floors.
In T-SQL, I would use a cursor, and I assume I need to do the same kind of thing in Oracle, but I can't figure out the syntax.
