SQL运算符

例子

实际查询条件

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（默认）

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（异或）

xor

两个输入中只有一个是true时，结果为true，否则为false，例子略。

1 xor 1 = 0

exp

综合表达式

$map[‘id‘] = array(‘exp‘,‘in(1,3,8)‘);

$map[‘id‘] = array(‘in‘,‘1,3,8‘);
