It was originally a Functional programming language with unique text list-handling features inspired by Ray Ozzie's prior use of Icon and Lisp. The Formula language engine was rewritten by Damien Katz for Notes and Domino 6. [1] New features were added to the language, such as looping and dynamic execution, and performance was improved. [2]
DELETE requires a shared table lock; Triggers fire; DELETE can be used in the case of: database link; DELETE returns the number of records deleted; Transaction log - DELETE needs to read records, check constraints, update block, update indexes, and generate redo / undo. All of this takes time, hence it takes time much longer than with TRUNCATE
In 493 AD, Victorius of Aquitaine wrote a 98-column multiplication table which gave (in Roman numerals) the product of every number from 2 to 50 times and the rows were "a list of numbers starting with one thousand, descending by hundreds to one hundred, then descending by tens to ten, then by ones to one, and then the fractions down to 1/144 ...
An identity column differs from a primary key in that its values are managed by the server and usually cannot be modified. In many cases an identity column is used as a primary key; however, this is not always the case. It is a common misconception that an identity column will enforce uniqueness; however, this is not the case. If you want to ...
In an analogous way, one can obtain finite difference approximations to higher order derivatives and differential operators. For example, by using the above central difference formula for f ′(x + h / 2 ) and f ′(x − h / 2 ) and applying a central difference formula for the derivative of f ′ at x, we obtain the central difference approximation of the second derivative of f:
History: Fiction or Science? Chronology volumes 1–7. The new chronology is a pseudohistorical theory proposed by Anatoly Fomenko who argues that events of antiquity generally attributed to the ancient civilizations of Rome, Greece and Egypt actually occurred during the Middle Ages, more than a thousand years later.
The first Phantom air-to-air victory of the war took place on 9 April 1965 when an F-4B from VF-96 Fighting Falcons piloted by Lieutenant (junior grade) Terence M. Murphy and his RIO, Ensign Ronald Fegan, shot down a Chinese MiG-17. The Phantom was then shot down, probably by an AIM-7 Sparrow from one of its wingmen. [24]
In calculus, the Leibniz integral rule for differentiation under the integral sign, named after Gottfried Wilhelm Leibniz, states that for an integral of the form () (,), where < (), < and the integrands are functions dependent on , the derivative of this integral is expressible as (() (,)) = (, ()) (, ()) + () (,) where the partial derivative indicates that inside the integral, only the ...
