The relational operator determine the relationship that one operand has to the other. Specifically, they determine equality and ordering. Table 4.2 shows relational operators. Table 4.2 Relational Operators The outcome of these operations is a boolean value. The relational operators are most frequently ...
quasi-modal operatorTarski spacesstone spacesIn this work, we study the relational representation of the class of Tarski algebras endowed with a subordination, called subordination Tarski algebras. These structures were introduced in a previous paper as a generalisation of subordination Boolean algebras. ...
<= Checks if the value of left operand is less than or equal to the value of right operand, if yes then condition becomes true. (A <= B) is true. Example of Relational OperatorConsider the following example program to understand all the relational operators available in Scala programming la...
A Case statement contains an Is clause but no comparison operator such as = or >. If a Case statement does not include an operator, = is assumed and Is is not used.Error ID: BC30239To correct this errorRemove the Is keyword or follow it with a comparison operator....

ICs can be written in a modal logic to use a belief operator to express beliefs that the database must satisfy. He explores Levesque’s KFOPCE [Levesque, 1984], an epistemic modal logic, as a suitable framework. Demolombe and Jones [Demolombe and Jones, 1996], view ICs as statements ...
The == operator returns true if its two operands are equal and false otherwise. When == operator is applied on primitive operands, it tests whether the operand values themselves are identical. For operands of reference types, however, it tests whether the operands refer to the same object or...
The shaped query on which the operator is applied. predicate LambdaExpression The predicate supplied in the call. returnType Type The return type of result. returnDefault Boolean A value indicating whether default should be returned or thr...
Granules in a many-to-many entity-relationship system are constructed based on so-called representations, which correspond to Boolean combinations of descriptors over two information systems (Definition 11). An atomic representation is the expression of the form (a : a(x)), where a is an attrib...
ValidateHasResults Opt Boolean that defaults to “false”. If “true” indicates that Insert and Update commands should error at runtime if anything other than exactly one row is returned in the result set of the command. If this is “false”, then if the result set is present there can...
