PL/SQL :: Developing ETL Instead Of Using Tools
Apr 10, 2013
I've been developing for many years in pl/sql and c-shell scripting (Unix) for managing ETL processes in order to load and perform data into databases and data warehouses.
Even if I've rarely used tools like Pentaho and never used Oracle Warehouse Builder, according to you is it possible to claim that an analyst/programmer has developed ETL processes only by using classic developing (plsql, c-shell, external tables, ...)?
For a forthcoming new project I'd like to work for as a data warehouse analyst/programmer for ETL processes, I'd like to know whether I can claim to be able to write ETL procedures even if I don't use data integration tools.

Am using Oracle 9i and developing stored procedures in SQL Developer. Have a situation where one stored procedure A is calling another B. Stored proc B builds the SQL based on parameters passed in. For one of the parameters i would like to use a bind variable in the SQL that proc B builds. The bind var is passed back to proc A as a part of the SQL string. In proc A, i then try to bind that variable to a parameter(value), however, the bind does not seeem to work.
The SQL string contained in v_SQLStatement defined as VARCHAR(4000) that is passed back to proc A looks like:
SELECT em.event_title AS event_name,
e.start_date AS start_date,
e.end_date AS end_date
FROM d_event_ml em
inner join d_event e
ON em.event_id = e.event_id
WHERE em.language_id = 46
AND e.end_date >= SYSDATE
AND e.stream_id IN ( :v_x1 )
AND e.event_id IN (SELECT event_id
FROM d_events_seas
[code]....
and o_EventList is defined as REF CURSOR. i'm experiencing is that :v_x1 stays as :v_x1 and does not change.This is my first attempt at using bind vars. URL....

I am tasked to develop and application using Apex 4.2.2.00.11 and Oracle Database 10.2.0.4 on a Windows 2003 Server. This application needs to support different time zones. Briefly, a user in timezone A should be able to create a record with a date in timezone B and the users should be able to view the records in their timezones. What is the best method? Should I maintain a Timezone field for each user site or even per transaction, or is using "Automatic Time Zone" feature in Globalization section of Application Properties sufficient? I have developed Apex applications before, but they did not have to have different time zones, so I am not sure how I should build my database schema. Do you guys store everything as UTC and display values based on user's Timezone setting? I am aware of the Timestamp with Local Timezone data type.

which are recommended Tool for load testing (for performance) on Oracle-J2EE, 3 Tier applications?
Is 'Oracle Application Test Suite' the best for such test where we can simulate numbers of users and their various actions?
Does it come with Oracle Database license or we have to buy it separately?

I'm looking for 3 simple things.
1) A reverse engineering tool that I can point to an Oracle schema and get a "baseline" script to re-create that schema from scratch, with decently formatted DDL files (1 per object) neatly organized in a directory tree (by object type) and called in the correct order. Icing on the cake would be an option to pass the tool a list of tables containing static data and get DMLs to populate (insert) those tables as part of the script.
2) a diff tool that I can point to a pair of Oracle instances (source and target) containing a given schema and get a "delta" script to alter the target schema so that it becomes identical to the source schema. If data loss occurs on the target instance (i.e. drop a column) I would like to find a warning comment inserted in the script (e.g. "-- Attention: data migration DML needed here?"). Icing on the cake would be an option to pass the tool a list of tables containing static data and get DMLs to update (delete, update and insert) the data in the target tables to become identical to the contents in the source tables *without* deleting and re-inserting all rows (or dropping, recreating and repopulating the table).
3) I would like the above two tools (that, as you will have recognized, are basic to putting your database design under version control) to be open-source, with a command-line interface and a vibrant community backing them.

I usually work in oracle using the different editors like toad, plsql developer etc. I felt command line is good utility because of various supporting points. I am not sure what kind of command line tools is available/used. I am using pretty straight command line
(run->cmd, then enter username and password).
The best command line tools available. What is generally used command line tools.

2 questions:
I'm fighting with a fairly large set of dynamic queries created by some developer (often SQL is over 2MB) accessing plenty of tables having something like 1000 columns...
Formatting of such query takes ages in Toad while is pretty fast in Oracle SQL Developer... SQL developer is running plenty write operations in local app data directory... moving it onto a ram-drive didn't worked how I could optimize Toad's formatter?
I'm often accessing a small table which has 100 columns of type VARCHAR2(4000).
The problem is that I cannot see the results of such query as Toad is throwing "out of memory" exception. How to deal with that?

I'm a Data Manager recently hired at a small company that uses InForm as our data management tool. We are currently not set up with any type of SQL tool to query the database. Consequently, I feel like I'm trying to clean data with one hand tied behind my back. I have two questions:
1) Is there any sort of built in feature in InForm for using SQL statement to query the data? (I'm not really a fan of the built in Cognos feature.)
2) Any tool that is easy to install/configure?
I'm facing some resistance here, so I'm looking for a really easy/cheap solution. I've used SQL Developer before, and I know that's free, but is it easy to set-up?

Many moons ago, at a previous employer, I had access to the SQL Monitor tool that came with TOAD. I could really use an alternative to this now, as we don't have TOAD here, and it would need to be free. I'm getting a problem with a forms update failing, and I really need to see what's actually being submitted to the database by the form. We're still stuck on Forms 6 by the way

Had some annoying problems with installing TOAD on Windows 7, 64 bit.Got I working now, but anyway I thought I share it here.
1. Toad 10.1(latest) doesn't work with the Oracle 64 bit client. The problem is that this is a limitation of the tool Quest uses to build Toad. So that will not work in a "near" future.
2. Never choose the default suggested installation path which is "C:Program Files(86)",that will mess it up totally. Point to a new or existing directory without brackets.

I have a proc created which dynamically creates scripts to be executed, e.g. using DBMS_OUTPUT.PUT_LINE it creates the following scripts to be executed:
EXEC D_Q_TST1('PARAM1','PARAM2','PARAM3');
EXEC D_Q_TST2('PARAM1','PARAM2','PARAM3');
EXEC D_Q_TST3('PARAM1','PARAM2','PARAM3');
EXEC D_Q_TST4('PARAM1','PARAM2','PARAM3');
EXEC D_Q_TST5('PARAM1','PARAM2','PARAM3','PARAM4','PARAM5');
Now, what I am really looking for is to explore options where we can spool the results into a file and run another proc to execute all of these proc through it.
let me know if my request is not clear.

How I go about writing a query that doesn't see the '&' symbol as a substitution character. The problem I have is:
select replace
( fnd_profile.value( 'XXBPO_URL')
, '&DOCID'
, ai_dfv.bpo__document_link
) document_link
from ap_invoices_all ai
, ap_invoices_all_dfv ai_dfv
where 1=1
-- where clause
The problem above is that instead of replacing the characters &DOCID with the required value, it is prompting for input.
