PL/SQL refers to a class as an "Abstract Data Type" (ADT) or "User Defined Type" (UDT), and defines it as an Oracle SQL data-type as opposed to a PL/SQL user-defined type, allowing its use in both the Oracle SQL Engine and the Oracle PL/SQL engine. The constructor and methods of an Abstract Data Type are written in PL/SQL.
List of oracular statements from Delphi. Lycurgus Consulting the Pythia (1835/1845), as imagined by Eugène Delacroix. Pythia was the priestess presiding over the Oracle of Apollo at Delphi. There are more than 500 supposed oracular statements which have survived from various sources referring to the oracle at Delphi.
The detailed semantics of "the" ternary operator as well as its syntax differs significantly from language to language. A top level distinction from one language to another is whether the expressions permit side effects (as in most procedural languages) and whether the language provides short-circuit evaluation semantics, whereby only the selected expression is evaluated (most standard ...
Development of applications commonly takes place in Java (using Oracle JDeveloper) or through PL/SQL (using, for example, Oracle Forms and Oracle Reports/BIPublisher). [ 32 ] [ 33 ] Oracle Corporation has started [ 34 ] a drive toward "wizard"-driven environments with a view to enabling non-programmers to produce simple data-driven applications.
If-then-else flow diagram A nested if–then–else flow diagram. In computer science, conditionals (that is, conditional statements, conditional expressions and conditional constructs) are programming language constructs that perform different computations or actions or return different values depending on the value of a Boolean expression, called a condition.
Comparison of individual. languages. Comparison of Java and .NET platforms. ALGOL 58's influence on ALGOL 60. ALGOL 60: Comparisons with other languages. Comparison of ALGOL 68 and C++. ALGOL 68: Comparisons with other languages. Compatibility of C and C++. Comparison of Pascal and Borland Delphi.
Turing reduction. In computability theory, a Turing reduction from a decision problem to a decision problem is an oracle machine that decides problem given an oracle for (Rogers 1967, Soare 1987). It can be understood as an algorithm that could be used to solve if it had available to it a subroutine for solving .
Dangling else. The dangling else is a problem in programming of parser generators in which an optional else clause in an if–then (–else) statement results in nested conditionals being ambiguous. Formally, the reference context-free grammar of the language is ambiguous, meaning there is more than one correct parse tree.
