only sets the lock on the @var variable, not on the individual elements of the array Therefore, another call to lock($var[0]) will not block Also, references are only followed to one level, such that an attempt to lock the reference \$var will work, but trying to lock \\$var will not work Once a variable is locked, you can control the unlocking process with three separate functions: cond_wait, cond_signal, and cond_broadcast The cond_wait function is the main one It unlocks the variable and blocks until another thread does a cond_signal or cond_broadcast call for the variable The function therefore enables you to wait until another process indicates (either through the cond_signal or cond_broadcast function) that the thread has finished using the variable Once the cond_wait unblocks, the variable is locked again The cond_wait function takes one argument a locked variable and unblocks a random thread that is waiting for the variable via cond_wait It is not possible to specify which thread is unblocked You can unblock all waiting threads using the cond_broadcast function, which also takes a single (locked) variable as an argument This is a very complicated description of what is basically a simple process of indicators and signals that allow you to control access to a variable Consider that you have two threads, A and B, and they both want to update a variable $var Thread A locks the variable with lock and then starts its update Meanwhile, thread B decides that it needs to update the variable, so it calls cond_wait($var), effectively halting the B thread until A has finished Once A has completed the update, it calls cond_signal($var), indicating to thread B that it has finished with the variable The cond_wait function called from thread B then locks the variables for its own use and continues execution This process of waiting and signaling the status of locked variables allows you to control access to them and prevent the corruption that could occur if two threads were to update the variable at the same time Fortunately, in the example, there are only two threads, and so the locking method is relatively straightforward In a multithreaded process, controlling access to a single variable may be more difficult You may want to try using either the queuing or semaphore methods for divining information about the variables that you want to share among processes.

select department_name from departments where department_name like '%ing';

Since subroutines are just other objects, you can also lock them using the lock function However, unlike locks on variables, a lock on a subroutine is mandatory no one else but the thread with the lock can use that subroutine There are times, however, when you want a subroutine to be locked automatically on execution You can set this behavior using the locked attribute when you define the subroutine For example:

birt ean 13, code 39 barcode microsoft word, birt pdf 417, birt ean 128, birt code 128, birt upc-a

NULL values inevitably find their way into database tables It is sometimes required that only those records that contain a NULL value in a specific column are sought The IS NULL operator selects only the rows where a specific column value is NULL Testing column values for equality to NULL is performed using the IS NULL operator instead of the is equal to operator (=) Consider the following query, which fetches the LAST_NAME column from the EMPLOYEES table for those rows that have NULL values stored in the COMMISSION_ PCT column:

15:

sub process : locked { }

select last_name from employees where commission_pct is null;

Although you can use ordinary variables for exchanging information between running threads, it often requires careful use of the lock function to ensure you are using the right value at the right time If all you want to do is exchange simple information between threads, a better method is to use a simple stack However, you can t use a simple scalar array, since that will exhibit the same (if not more complex) problems regarding locking and access you already know about regarding the lock and other functions Instead, the Perl thread system supports a message queue object This is basically a standard array, except that it is thread compatible and so handles additions and removals from the list safely, without the normal risk to corruption of the variables To create a new queue:

The Execution Environment 6 A Simpler Programming Model 6 Safety and Security 8 Powerful Tools Support 8 Deployment, Packaging, and Support 8 Metadata 9 Assemblies 9 Language Interop 10 Attributes 10.

This WHERE clause reads naturally and retrieves only the records that contain NULL COMMISSION_PCT values

use Thread::Queue; my $queue = new Thread::Queue;

The list operates strictly on a LILO (last in, last out) format, so new entries are added to the end of the list, and entries are removed and returned from the start of list The enqueue method adds a list of values to the end of the queue:

Boolean or logical operators enable multiple conditions to be specified in the WHERE clause of the SELECT statement This facilitates a more refined data extraction capability Consider isolating those employee records with FIRST_NAME values that begin with the letter J and that earn a COMMISSION_PCT greater than 10 percent First, the data in the EMPLOYEES table must be restricted to FIRST_NAME values like J% , and second, the COMMISSION_PCT values for the records must be tested to ascertain if they are larger than 10 percent These two separate conditions may be associated

$thread->enqueue('Martin', 'Brown');

using the Boolean AND operator and are applied consecutively in a WHERE clause A result set conforming to any or all conditions or to the negation of one or more conditions may be specified using the OR, AND, and NOT Boolean operators respectively
