| SQL運(yùn)算符 | 例子 | 實(shí)際查詢條件 | |
|---|---|---|---|
| eq | = | $map['id'] = array('eq',100); | 等效于：$map['id'] = 100; |
| neq | != | $map['id'] = array('neq',100); | id != 100 |
| gt | > | $map['id'] = array('gt',100); | id > 100 |
| egt | >= | $map['id'] = array('egt',100); | id >= 100 |
| lt | < | $map['id'] = array('lt',100); | id < 100 |
| elt | <= | $map['id'] = array('elt',100); | id <= 100 |
| like | like | $map<'username'> = array('like','Admin%'); | username like 'Admin%' |
| between | between and | $map['id'] = array('between','1,8'); | id BETWEEN 1 AND 8 |
| not between | not between and | $map['id'] = array('not between','1,8'); | id NOT BETWEEN 1 AND 8 |
| in | in | $map['id'] = array('in','1,5,8'); | id in(1,5,8) |
| not in | not in | $map['id'] = array('not in','1,5,8'); | id not in(1,5,8) |
| and（默認(rèn)） | and | $map['id'] = array(array('gt',1),array('lt',10)); | (id > 1) AND (id < 10) |
| or | or | $map['id'] = array(array('gt',3),array('lt',10), 'or'); | (id > 3) OR (id < 10) |
| xor（異或） | xor | 兩個(gè)輸入中只有一個(gè)是true時(shí)，結(jié)果為true，否則為false，例子略。 | 1 xor 1 = 0 |
| exp | 綜合表達(dá)式 | $map['id'] = array('exp','in(1,3,8)'); | $map['id'] = array('in','1,3,8'); |
exp 不是一個(gè)運(yùn)算符，而是一個(gè)綜合表達(dá)式以支持更復(fù)雜的條件設(shè)置。exp 的操作條件不會(huì)被當(dāng)成字符串，可以使用任何 SQL 支持的語(yǔ)法，包括使用函數(shù)和字段名稱。
