PL/SQL Logical Operators evaluate whole function

Question

I know in C like languages logical operators are evaluated one at a time so:

false && really_expensive_function()

is doesn't result in the function being called (I can't remember the CS name for this). Does the same happen in PL/SQL or do I need to break the IF parts out to separate blocks?

Answer 1

The CS name is short-circuiting (wikipedia entry on short-circuit evaluation) and yes, plsql does exactly that.

Answer 2

I think the term you are looking for is "lazy evaluation". You may want to look at this question.
