Genetics and Tuberculosis: Novartis Foundation Symposium 217
Genetics and Tuberculosis Chairman: Douglas younger 1998 extra humans die every year from tuberculosis than from the other infectious disorder, the once a year loss of life toll being virtually 3 million (over ninety five% of that are in constructing nations) with 8 million new instances being clinically determined each year. it really is expected that one-third of the world's inhabitants - approximately billion humans - is now contaminated, of which 5-10% will boost the illness.

Sample text
That is, normal execution stops and control transfers to the exception-handling part of your PL/SQL block or subprogram. To handle raised exceptions, you write separate routines called exception handlers. Predefined exceptions are raised implicitly by the runtime system. For example, if you try to divide a number by zero, PL/SQL raises the predefined exception ZERO_ DIVIDE automatically. You must raise user-defined exceptions explicitly with the RAISE statement. You can define exceptions of your own in the declarative part of any PL/SQL block or subprogram.
In the last example, the implicit decimal point shifted three places to the right. 005 As the following example shows, if the value of a numeric literal falls outside the range 1E-130 .. 10E125, you get a compilation error: DECLARE n NUMBER; BEGIN n := 10E127; -- causes a ’numeric overflow or underflow’ error Character Literals A character literal is an individual character enclosed by single quotes (apostrophes). Character literals include all the printable characters in the PL/SQL character set: letters, numerals, spaces, and special symbols.
Higher Productivity PL/SQL adds functionality to non-procedural tools such as Oracle Forms and Oracle Reports. With PL/SQL in these tools, you can use familiar procedural constructs to build applications. For example, you can use an entire PL/SQL block in an Oracle Forms trigger. You need not use multiple trigger steps, macros, or user exits. Thus, PL/SQL increases productivity by putting better tools in your hands. Moreover, PL/SQL is the same in all environments. As soon as you master PL/SQL with one Oracle tool, you can transfer your knowledge to other tools, and so multiply the productivity gains.
