Description
| Operator | Description |
|---|---|
| AND | True if <condition1> and <condition2> conditions are both true, otherwise False |
| NOT | True if the <condition> is false, otherwise False |
| OR | True if <condition1> or <condition2> is true or if both conditions are true, otherwise False |
| XOR | True if <condition1> or <condition2> is true but not both, otherwise False |
Example
// AND SELECT name, address, balance, cost*1.15; FROM accounts; WHERE paid_date < date() AND ord_value > 10000; ORDER BY name, paid_date // NOT SELECT name, address, balance, cost*1.15; FROM accounts; WHERE paid_date < date() AND NOT ord_value BETWEEN 0 AND 10000; ORDER BY name, paid_date // OR SELECT name, address, balance, cost*1.15; FROM accounts; WHERE paid_date < date() OR ord_value > 10000; ORDER BY name, paid_date // XOR SELECT name, address, balance, cost*1.15; FROM accounts; WHERE paid_date < date() OR ord_value > 10000; ORDER BY name, paid_date
