Source sentences:
text: When you get a single TRUE result, the whole predicate is TRUE .
text: But most people have lots of trouble seeing why the ALL predicate is TRUE .
text: If our predicate is TRUE, then the element will be selected.
text: all rows for which the predicate in the WHERE clause is True are affected (or returned) by the SQL DML statement or query.
text: Informally, a predicate is a statement that may be true or false depending on the values of its variables.
text: Thus, a predicate P(x) will be true or false, depending on whether x belongs to a set.
text: There are two key types of legal expressions: terms, which intuitively represent objects, and formulas, which intuitively express predicates that can be true or false.
text: Intuitively, a first-order formula is a statement about these objects; for example, ∃ x P ( x ) {\displaystyle \exists xP(x)} states the existence of an object x such that the predicate P is true where referred to it.
text: E.g. filter is a function in many languages which takes a predicate and a list as arguments, and returns the items in the list for which the predicate is true.
text: We say that a predicate is true when it returns a non- nil value, and is false when it returns nil ; that is, it is true or false according to whether the condition being tested is true or false.
text: The basic idea is that each instruction is associated with a predicate (the word here used similarly to its usage in predicate logic) and that the instruction will only be executed if the predicate is true.
text: Informally, a predicate is a statement that may be true or false depending on the values of its variables.
text: Thus, a predicate P(x) will be true or false, depending on whether x belongs to a set.
text: At the time of evaluation of the composed predicate, If this Predicate is true then other predicate is not even evaluated.
text: Alternatively, a notation is used (in the model theory, which should be odd to a "pure" model theorist) to stand for these kinds of predicates: $(\forall x)P(x)$ is read as "for all ex capital pee of ex" and asserts (in model theory) that the predicate $P(x)$ is true for any argument which is an individual in the domain, $(\exists x)P(x)$ is read "there exists an ex such that capital pee of ex" and asserts that the predicate $P(x)$ is true for at least one argument which is an individual in the domain.

text: For example, most functional languages have some kind of find function that operates on sequences, or lists that returns the first element, for which the predicate is true .
