Question

对于这样的事情正确的查询是什么:

UPDATE table SET field1 WHERE field2 = val and field3 = val AND val AND val;

The SQL IN condition (sometimes called the IN operator) allows you to easily test if an expression matches any value in a list of values. It is used to help reduce the need for multiple OR conditions in a SELECT, INSERT, UPDATE, or DELETE statement.

UPDATE table SET field1=newVal WHERE field2 = val and field3 In (val1, val2, val3);
