expression 1, expression 2: Expressions with values of any type. If the condition is evaluated to true, the expression 1 will be evaluated. If the condition is evaluated to false, the expression 2 will be evaluated. It should be read as: "If condition is true, assign the value of expression 1 to result.
SQL Server Management Objects (SMO) are .NET objects introduced by Microsoft as of Microsoft SQL Server 2005, designed to allow for easy and simple programmatic management of Microsoft SQL Server. [1] Using SMO, .NET programmers can design applications similar in functionality to Microsoft's SQL Server Management Studio.
The condition system is generalized thus: within the handler of a non-serious condition (a.k.a. continuable exception), it is possible to jump to predefined restart points (a.k.a. restarts) that lie between the signaling expression and the condition handler. Restarts are functions closed over some lexical environment, allowing the programmer to ...
The definition of an exception is based on the observation that each procedure has a precondition, a set of circumstances for which it will terminate "normally". [1] An exception handling mechanism allows the procedure to raise an exception [ 2 ] if this precondition is violated, [ 1 ] for example if the procedure has been called on an abnormal ...
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.
In addition to basic equality and inequality conditions, SQL allows for more complex conditional logic through constructs such as CASE, COALESCE, and NULLIF. The CASE expression, for example, enables SQL to perform conditional branching within queries, providing a mechanism to return different values based on evaluated conditions. This logic ...
C# (/ ˌ s iː ˈ ʃ ɑːr p / see SHARP) [b] is a general-purpose high-level programming language supporting multiple paradigms. C# encompasses static typing, [ 16 ] : 4 strong typing , lexically scoped , imperative , declarative , functional , generic , [ 16 ] : 22 object-oriented ( class -based), and component-oriented programming disciplines.
Predicates, which specify conditions that can be evaluated to SQL three-valued logic (3VL) (true/false/unknown) or Boolean truth values and are used to limit the effects of statements and queries, or to change program flow. Queries, which retrieve the data based on specific criteria. This is an important element of SQL.
