Effect
Formulates a conditions in a CDS view whose result is true or false. A condition is either a single relational expression, rel_expr, or an expression constructed from the Boolean operators NOT, AND, and OR in which parenthesized full conditions cond_expr using parentheses ( ... ) are possible.
The relational expressions rel_expr from which a condition cond_expr can be constructed are as follows:
The Boolean operators work as follows:
The operator NOT is a stronger binding than AND, which itself is a strong binding than OR. This produces implicit parentheses, which can be overridden by explicit parentheses.
