6. Always log error (and backtrace) before re-raising the exception.
 
02:28
When you re-raise an exception, you will reset the backtrace (the track back to the line on which the error was raised) and might change the error code (if you raise a different exception to propagate the exception "upwards"). So it is extremely important to call you error logging subprogram (see previous Good to Know) before you re-raise an exception.

9. Send app-specific error message with RAISE_APPLICATION_ERROR.
 
02:26
If you execute a SELECT-INTO that does not identify any rows, the PL/SQL runtime engine raises: ORA-01403 and the error message (retrieved via SQLERRM or DBMS_UTILITY.FORMAT_ERROR_STACK) is simply "No data found". That may be exactly what you want your users to see. But there is a very good chance you'd like to offer something more informative, such as "An employee with that ID is not in the system." In this case, you can use RAISE_APPLICATION_ERROR, as in: CREATE OR REPLACE PACKAGE BODY employees_mgr IS FUNCTION onerow (employee_id_in IN hr.employees.employee_id%TYPE) RETURN hr.employees%ROWTYPE RESULT_CACHE IS l_employee hr.employees%ROWTYPE; BEGIN SELECT * INTO l_employee FROM hr.employees WHERE employee_id = employee_id_in; RETURN l_employee; EXCEPTION WHEN NO_DATA_FOUND THEN raise_application_error ( -20000, 'An employee with that ID is not in the system.'); END; END; Related blog post: http://stevenfeuersteinonplsql.blogspot.com/2016/03/nine-good-to-knows-about-plsql-error.html ======================================== Practically Perfect PL/SQL with Steven Feuerstein Copyright © 2015 Oracle and/or its affiliates.

8. Use LOG ERRORS to suppress SQL errors at the row level.
 
06:23
The impact of a non-query DML statement is usually "all or nothing". If my update statement identifies 100 rows to change, then either all 100 rows are changed or none are. And none might be the outcome if, say, an error occurs on just one of the rows (value too large to fit in column, NULL value for non-NULL column, etc.). But if you have a situation in which you would really like to "preserve" as many of those row-level changes as possible, you can add the LOG ERRORS clause to your DML statement. Then, if any row changes raise an error, that information is written to your error log table, and processing continues. IMPORTANT: if you use LOG ERRORS, you must must must check that error log table immediately after the DML statement completes. You should also enhance the default error log table.

About that error: ORA-06502: numeric or value error
 
12:11
"ORA-06502: numeric or value error" is one of the most commonly occurring and irritating errors for PL/SQL developers. Value too big for its "container"? Trying to stuff a non-numeric string value into a number through implicit conversion? [naughty naughty] In this video, Steven takes a close look at ORA-06502, exploring the ways it can be raised and how best to deal with those scenarios. ============================ Practically Perfect PL/SQL with Steven Feuerstein Copyright © 2015 Oracle and/or its affiliates.

4. Outer block unaware of error if not re-raised.
 
03:03
If you do not re-raise an exception in your exception handler, the outer block doesn't know an error has occurred. Just sayin'. You have a subprogram that invokes another subprogram (or nested block). That "inner" subprogram fails with an exception. It contains an exception handler. It logs the error, but then neglects to re-raise that exception (or another). Control passes out to the invoking subprogram, and it continues executing statements, completely unaware that an error occurred in that inner block. Which means, by the way, that a call to SQLCODE will return 0. This may be just what you want, but make sure you do this deliberately.

How NOT to Handle Exceptions - Part 1
 
06:43
In which Steven Feuerstein takes a look at several ways you should never handle an exception in your PL/SQL block. To summarize: 1. Don't swallow up or hide errors. 2. Don't simply display error information on the screen through a call to DBMS_OUTPUT.PUT_LINE. 3. Don't handle and re-raise without adding value (logging or doing *something*).

7. Compile-time warnings help avoid "WHEN OTHERS THEN NULL".
 
03:23
One of Tom Kyte's favorite pet peeves, the following exception sections "swallow up" errors. EXCEPTION WHEN OTHERS THEN NULL; EXCEPTION WHEN OTHERS THEN DBMS_OUTPUT.PUT_LINE (SQLERRM); In fact, any exception handler that does not re-raise the same exception or another, runs the risk of hiding errors from the calling subprogram, your users, and yourself as you debug your code. Generally, you should log the error, then re-raise it. There are certainly some cases in which this advice does not hold (for example: a function that fetches a single row for a primary key. If there is no row for the key, it's not an application error, so just return NULL). In those cases, include a comment so that the person maintaining your code in the distant future knows that you weren't simply ignoring the Wisdom of the Kyte. Example: EXCEPTION WHEN OTHERS THEN /* No company or this ID, let calling subprogram decide what to do */ RETURN NULL; One way to avoid this problem is to turn on compile-time warnings. Then when your program unit is compiled, you will be warned if the compiler has identified an exception handler that does not contain a RAISE statement or a call to RAISE_APPLICATION_ERROR.

How to Debug Queries Using Devel
 
03:43
By: Ivan Zugec http://webwash.net | http://twitter.com/webwashnet Modules: - Devel (https://drupal.org/project/devel) Transcript: In Drupal 7 you can query the database in two ways; using a static query or a dynamic query. A static query is the simplest of the two, all you need to do is pass a query and arguments using the db_query function. Most of your queries should be a static query because they are the fastest and the simplest. Dynamic queries on the other hand allow other modules to modify a query by implementing the hook_query_alter hook. But beware dynamic queries are slower than static queries. Writing and debugging a dynamic query can be tough because you can't easily see the generated SQL string. Using the Devel module you could turn on the "Display query log" setting, but then you'll be bombarded with a lot of queries to sort through. The easiest way to view the generated SQL string is to use the dpq function that comes with Devel. Simply pass the query object through to the dpq function and the SQL string will be displayed in the message region. However, the function only works for dynamic queries that use the "db select" function. Let me now demonstrate how to use the dpq function. Here I have a basic module with a single menu item and a callback function. If I go to ww dash example it'll simply display whatever is returned in this function. Let's paste in a simple dynamic query, all it does is query all nodes which are articles. And then here we pass the query object to the dpq function. Now, if we refresh the page, we should see the SQL string in the message area. You can use this SQL string to query the database directly. The only thing we need to do is remove these curly brackets. They are added by Drupal's database abstraction layer. Let's do that right now, I'll copy the query and open Sequel Pro which is a open source MySQL database manager. If you use a Mac I highly recommend this application. Click on Query and paste in the SQL string, don't forget to remove the curly brackets and then click on "Run Current". We can see our query results in the table below. If you don't want to use Devel to print the SQL string, just print the toString method on the query object. You can use the "print r" or Drupal's debug function. Now let's use the toString method. We'll add it below the dpq function so we can see both of them at the same time. Refresh the page, and now we can see two SQL strings. The first one is printed by dpq and the second is by printing the toString method. The biggest difference between the two is that the dpq function prints actual placeholder variables, in this example it's Article. Whereas, the toString method just prints db_condition_placeholder and that's it. This makes it very difficult to copy the SQL string into phpMyAdmin or Sequel Pro.

Setting up a Network Connection in Linux (Backtrack)
 
05:31
This tutorial demonstrates how to configure a network connection in Linux (Backtrack specifically). Normally a network connection can be automatically established and configured but in some situations this isn't the case. In such instances, an IP, Gateway, Subnet Mask, and DNS must be assigned the the network adapter. This tutorial will also show how to configure a wireless adapter to connect to a desired network. - Commands Used: ifconfig (Shows a listing of recognized network interfaces on the system) sudo ifconfig [INTERFACE] up (Enables the specified network interface) sudo ifconfig [INTERFACE] [IP ADDRESS] netmask [SUBNET MASK] (Assigns an IP Address to the network interface. A LAN IP should begin with 192.168.xxx.xxx [EX: 192.168.0.112]. Netmask will assign a subnet mask to the interface as well which is normally 255.255.255.0) sudo iwconfig [INTERFACE] mode managed (Sets the interface to managed mode) sudo iwconfig [INTERFACE] essid [NAME OF NETWORK] key [ENCRYPTION KEY] (Connects you to the specified secure network) sudo route add default gateway [GATEWAY IP ADDRESS] (Assigns the default gateway to the interface. This will be the IP Address of your router which varies from model to model. Most will be either 192.168.0.1 or 192.168.1.1) sudo sh -c "echo nameserver [DNS IP] [GREATER THAN SYMBOL] /etc/resolv.conf" (This writes the DNS IP to your resolv.conf file. This is needed to resolve domain names to IP addresses. Your DNS will either be assigned by your ISP, your router's IP, or a public DNS can be used) ipconfig /all (This command used within Command Prompt on a Windows OS will display your adapter settings as well as provide all the information needed above)
