Instead, the less-than-or-equal operator is simply defined as “not greater than,” and the greater-than-or-equal operator is defined as “not less than.” The one exception occurs when either operand is (or converts to) NaN, in which case all four comparison operators return false....
Expressions with type enum shall not be used as operands to built- in operators other than the subscript operator [ ], the assignment operator =, the equality operators == and !=, the unary & operator, and the relational operators <, <=, >,

Alternatively, the same result could be obtained by using the SQL outer join operator in conjunction with COALESCE, as here: SELECT SNO , COALESCE ( PNO ,'nil') AS PNO FROM ( S NATURAL LEFT OUTER JOIN SP ) AS TEMP Concluding Remarks ...
A long time ago (in a galaxy far, far away….), developers had to know exactly the number of operations they were coding. They knew by heart their algorithms and data structures because they couldn’t afford to waste the CPU and memory of their slow computers. ...
The operands in a logical expression, can be expressions which returns True or False upon evaluation. There are three basic types of logical operators: Logical AND: For AND operation the result is True if and only if both operands are True. The keyword used for this operator is and. ...
Using KeyPaths for types not used elsewhere in the query is a runtime error. In this snippet: table.where(\TestTable1.id > 20) \TestTable1.id is the KeyPath, pointing to the Int id for the object. 20 is the literal operand value. The > operator between them produces a CRUDBoolean...
