An expression in C is defined as 2 or more operands are connected by one operator and which can also be said to a formula to perform any operation. An operand is a function reference, an array element, a variable, or any constant. An operator is symbols like “+”, “-“, “/”, ...
you can use the empty string constant ("") as part of a criterion for a column in a query to evaluate the field values for that column, by entering the following as the criterion:<>"". In this example,<>is an operator and""is a constant. Used...
