Effect
Formulates a condition 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:
- Comparisons with relational operators
- Interval comparisons using BETWEEN
- Pattern comparisons using LIKE
- Checks on the null value using IS NULL
- Checks on the initial value using IS INITIAL
The Boolean operators work as follows:
- NOT negates the result of the following condition.
- An AND join is true if both joined conditions are true.
- An OR join is true if at least one of the joined conditions is true.
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.
