How to loop through the results of a select statement in a process flow?
Hello
I use Warehouse Builder 10 g R2.
I'm trying to implement a loop in a process stream that runs through the results of a select statement.
In pl/sql, it would be implemented as a for loop by using a slider, but I simply doesn't work how to do this using the loops in the process flow.
Someone at - it ideas?
Thank you

DDL lock on the object in a SELECT statement?
Environment:
Oracle 11.2.0.4 EE on Solaris
My client called me when she was trying to create a new index on a table and the process was just hanging. Also, she was not able to DELETE an existing index on the same table, which deal with hang them as well.
After reviewing the advice DBA_DDL_LOCKS, I found a DDL lock on the target of the index table.
The DDL lock is held by a process doing a SELECT on the table and this process worked for several hours.
There was no entry in V$ LOCKED_OBJECTS for the table.
I don't know, yet, what other operations prior to the SELECT statement in the offending process, I have not heard of the user yet.
I realize a DDL lock is placed on objects to prevent changes while specific operations are directed against this object, i.e. the DROP, UPDATE, compile the PACKAGE, etc.
Question: Is a select also place a DDL lock on a table at a level that would avoid a new index is created or an existing index having fallen?
Thank you very much for your comments!
Any reference to the resolution is greatly appreciated.
I searched some Concepts Developers Guide, SQL, even Google reference Guide.

> My question is now, this lock persists for the duration of the running query?
Easy enough to show that it is not.
Session1:
SQL> create table foo(bar number); Table created. SQL> insert into foo values(1); 1 row created. SQL> commit; Commit complete. SQL> variable x refcursor SQL> variable a number SQL> begin 2 open :X for select bar from foo; 3 end; 4 / PL/SQL procedure successfully completed.
Session 2:
SQL> drop table foo; Table dropped.
Note that I was able to remove the table even if select is still 'in progress' - the cursor is open.
If you really want to blow your mind, go back to the session 1:
SQL> begin 2 fetch :X into :a; 3 end; 4 / PL/SQL procedure successfully completed. SQL> print a A ---------- 1The picture has gone, but I can always look for him. However, try again:
SQL> / begin * ERROR at line 1: ORA-00604: error occurred at recursive SQL level 1 ORA-00942: table or view does not exist
Note that the forum software is stupid. is: followed by x. seems it's really important to have a smiley to lovey eyes in a technical forum.
Edit - and when you format the SQL code, it is removed completely and render invisible... silly.
I edited my code to use: X and the problem disappeared...

normalize the schema of the table in a select statement (without view)
Hello
I have a table storing a physical value, mean temperature for different locations every minute. The table schema is as following: timestamp (datetime), rental (string), value (number).
Do you know a way to have a select statement, return of lines with the following data: timestamp, the value at location1, value of place.2 guests, etc.
This will help me to create time series in he same diagram in my reporting tool.
This may be possible with a view, but I don't have access to the database, the best I can do is set my a data source such as a select statement.
Thank you!

What you're asking about is called pivoting. The ahs Forum FAQ page devoted to this topic: Re: 4. How can I convert rows to columns?
Since you're using Oracle 10, you cannot use the SELECT... Function PIVOT; You can use GROUP BY and CASE instead.
Do ' t worry not about creating views. What you can do with views, you can also do it using a WITH clause in your query.
If you get stuck, please post some sample data (CREATE TABLE and only relevant columns, INSERT statements) for all of the tables involved and also to publish the results you want from this data, as well as your best attempt to query a specific question.
Explain, using specific examples, how you get the results desired from data provided.

can I get an exact part of the data in a select statement
Hi... good afternoon...
I want to extract the records from a table by the select statement. but I don't want to go as it's the folder. I want to go look for a particular part of the eacg folder in this column.
for example...
table_name = tab1
column_name = col1
the col1 contains datas as * 'customer research-cs', 'get client-gc', 'customer delete-cd' * etc etc...
now, while writing the select query, I want to get the descriptive result as get the customer, customer, customer search remove... .that is I don't want the symbols...
is it possible to achieve this?
PLSS suggest...You mean like these ways to do...

It's like with a knife like a spoon to eat porridge. Of course, it can work in a way. But why? A knife was never designed to be a spoon - and while it may work of porridge to eat, you'll have a hell of a time trying to use it to eat the soup. So, use the right tool.
In other words, a function is the wrong tool for the job. Use a procedure.

How to add an imaginary line in the result of the value of a SELECT statement.
Hello all-
I have requirment to add an imaginary line in the result set of a SELECT statement.
For example lets say it is a pay table having the following columns:
Number of Payment_id
status varchar2 (10)
number amount
date of payment_date
so here's the data: -.
Payment_id status amount payment_date
applied 1 100 12/07/2008
2 Reversed 200 01 / 06/2009
Applied 3 300 01 / 07/2009
Here is my SQL
Select * form payment where payment_date > = 01/01/2009
The output will be
2 Reversed 200 01 / 06/2009
Applied 3 300 01 / 07/2009
My desired output is less than
2 Reversed 200 01 / 06/2009
Applied 3 300 01 / 07/2009
reversed-200 2, 01 / 06/2009-(Dummy Row)
Third line here is the imaginary line that I add when the status is "reversed".
I would be very grateful for any help on this...
Thank you

NB. You may need to mess around with the order if that is not in the order you want. You did not mention what the rules were for all orders expected, so I composed my own * {;-)Also, I added a (cust_id) identifier to differentiate different types of payments, as is usually the case. Remove unless it is not applicable to your case.

the combination of two select statements to increase the maintainability and performance
Hi SQL Experts,
I use the Version of Oracle 11g DB and got both of the statements below.
My mind can´t get his head around it how and if these two can be combined.
They look like they could, but I can't figure out how... and I don't mean with a UNION ALL operation
My main goal is a gain in performance and maintainability.
SELECT *.
OF T_TEMP_42 T1 WHERE T1. MATRIX_2 IS NULL AND
(T1. BL_CODE | T1. YASSINE | T1. MATRIX_1 | T1. FIRMTYPE)
PO NO
(
SELECT BL_CODE. YASSINE | MATRIX_1 | FIRMTYPE
OF T_TEMP_41, WHERE MATRIX_2 IS NULL).
------------------------------------------------------------------------------------
SELECT *.
OF T_TEMP_42 T1 WHERE T1. MATRIX_2 IS NOT NULL AND
(T1. BL_CODE | T1. YASSINE | T1. MATRIX_1 | T1. MATRIX_2 | T1. FIRMTYPE)
PO NO
(
SELECT BL_CODE. YASSINE | MATRIX_1 | MATRIX_2 | FIRMTYPE
OF T_TEMP_41, WHERE MATRIX_2 IS NOT NULL
);
Thanks for your suggestions.
Try this
SELECT *.
OF T_TEMP_42 T1
WHERE (BL_CODE, YASSINE, MATRIX_1, FIRMTYPE, MATRIX_2) NOT IN (SELECT BL_CODE, YASSINE, MATRIX_1, FIRMTYPE, T_TEMP_41 MATRIX_2)
It came off really simple... maybe too simple

The execution plan changes for the same query.
Hi all
This issue was raised before also, but still not able to find the real cause of this.
Thread1:
Thread2:
It comes, sometimes hammers server 100% CPU utilization with free latch and buffer busy wait events.
We found a single query consumes high CPU usage that is run by different sessions.
This query have two types of execution plans, where one is accurate and is not (its primary key hit index index no appropriate means present on the table)
Because its primary key index hit repeatedly at various sessions, some sessions are powerful db file sequential read and a few sessions waiting buffer busy waits for event. Also during this time a few sessions waiting for latch free event.
My doubt is how to sql even with different literal values execution plan changes and causes a prob.

Hard analysis includes the re-evaluation of the best path.
Literal value is included in the assessment of the selectivity for the scan interval (log_seq >...)See

more the book of Jonathan Lewis which other threads, I believe that you already have.You must lower your CPU.
Previous discussions, if the situation is still the same, it sounded like hard analysis particularly with this SELECTION against the NEWSPAPER plays an important role in that.How to avoid this... why its different execution plan using (I mean bad index PK)
The points raised in the previous discussion remain valid.
-Do you have access to this SQL to change?
for example using bind variable or trick it if necessary due to problems caused by data as discussed in the previous thread.
- Or you could it repoint the view to a view and a hint?
-If a particular user makes this sql, could affect you cursor_sharing just for this user. If not, you should consider implementing pan-Canadian database.Oracle 8.1.6 still?

Sense of the GOAL: < text > in the execution plan
Hello
Could you please help me understand the following in the execution plan (Oracle10gR2)?
++++++++++++++
GOAL: HINT
OBJECTIVE: ANALYZE
++++++++++++++
For example, the following plan:
My question is: what do I do ' GOAL: HINT ' and ' GOAL: ANALYSIS "means? Not specifically for the plan above, just a question about how they mean when they show up in the plan of execution like the one above.Rows Execution Plan ------- --------------------------------------------------- 0 SELECT STATEMENT GOAL: HINT: FIRST_ROWS 301 HASH JOIN 200 TABLE ACCESS GOAL: ANALYZED (FULL) OF 'EP1' 303 NESTED LOOPS 304 TABLE ACCESS GOAL: ANALYZED (BY INDEX ROWID) OF 'EP3' 304 BITMAP CONVERSION (TO ROWIDS) 2 BITMAP OR 2 BITMAP INDEX (SINGLE VALUE) OF 'EP3_BI1' 2 BITMAP INDEX (SINGLE VALUE) OF 'EP3_BI2' 303 TABLE ACCESS GOAL: ANALYZED (BY INDEX ROWID) OF 'EP2' 606 INDEX GOAL: ANALYZED (UNIQUE SCAN) OF 'EP2_PK' (UNIQUE)
Thank you!

Error PLS-00428: an INTO clause in this SELECT statement
Dear Experts,
I'm new to PL/SQL programming
I try to run the following query, I get the error message.
Please help me solve the error.
declare
var_cd number (20);
Start
If: P1_TYP_CAT is not null then
SELECT max (CAT_cd + 1) as var_cd from IM_AST_CAT by CAT_cd;
insert into IM_AST_CAT (CAT_NM, CAT_CD) values ((upper (:P1_TYP_CAT)),(:var_cd));
on the other
RAISE_APPLICATION_ERROR ('-20001,' both Department and location must be provided ");
end if;
end;
In PL/SQL, must be used IN the clause when using SELECT statements.
SELECT max (CAT_cd + 1) as var_cd
in variable - it is missing in your code
from IM_AST_CAT by CAT_cd;
Your code should be
declare
var_cd number (20);
Start
If: P1_TYP_CAT is not null then
SELECT max (CAT_cd + 1).
in var_cd
of IM_AST_CAT
order of CAT_cd;insert into IM_AST_CAT (CAT_NM, CAT_CD) values (upper(:P1_TYP_CAT), var_cd);
on the other
RAISE_APPLICATION_ERROR ('-20001,' both Department and location must be provided ");
end if;
end;
For example:
DECLARE
l_first_name varchar2 (100);
BEGIN
Select first_name
in l_first_name
employees
where employee_id = 100;
END;
