An expression consisting of two numeric operands and a relational (comparison) operator evaluates to True (-1), False (0), or, if either or both of the operands is NULL, to NULL. For a description of the way in which LotusScript® treats the values True (-1) and False (0), see ...
template <class T, class Alloc> bool operator>= (const vector<T,Alloc>& lhs, const vector<T,Alloc>& rhs); Relational operators for vector Performs the appropriate comparison operation between thevectorcontainerslhsandrhs. Theequality comparison(operator==) is performed by first comparingsizes, and...
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....

Each relational operator examines one or more attribute values and evaluates to TRUE, FALSE or UNKNOWN, according to the defined behavior of the operator in the following table. In addition to the TRUE and FALSE values specified for each operator in the table, each relational operator MUST retu...
In other words, while comparing two objects == operator compares two memory locations, and of course, if two references point to a single object then memory location will be the same. Also, you cannot test two distinct strings for equality with this operator. ...
The filter I made an error on was to use an in ([otherquery].[item]) but the mistake was the query name (it was trying to filter based on itself). This generated the invalid relational operator ...the sql was crazy. I corrected it and the NOT filter then worked as expected. MFG...
Of course, relation types are no exception to the rule that the “=” comparison operator must be defined for every type; that is, given two relations r1 and r2 of the same relation type T, we must certainly be able to test whether they’re equal. Here’s a Tutorial D example: S ...
typing a query does not print anything at all, it just adds the created relation to the environment. If the query is inside another query, it does not create a relation per nested query in the environment; as an example of that, the secondprojectcommand used on thedisplayoperator does not...
