数据库_查询条件

参考example_index.php

//查找主键为1(默认为id)
$temp=\db\User::find(1);
dd($temp);

//查找id>1
$temp=\db\User::select(
[
	'id'=>[db_gt,1]
]);
dd($temp);

//查找id in 1,2
$temp=\db\User::select(
[
	'id'=>[db_in,[1,2]]
]);
dd($temp);

部分查询条件预定义,参考lp.core.php

const db_eq			='<>db_eq.1';		//等于
const db_neq			='<>db_neq.2';		//不等于

const db_gt			='<>db_gt.3';		//大于
const db_egt			='<>db_egt.4';		//大于等于

const db_lt			='<>db_lt.5';		//小于
const db_elt			='<>db_elt.6';		//小于等于

const db_like			='<>db_like.7';		//like
const db_notlike		='<>db_notlike.8';		//not like

const db_in			='<>db_in.9';		//in
const db_notin		='<>db_notin.10';		//not in

const db_isnull		='<>db_isnull.11';		//is null
const db_isnotnull		='<>db_isnotnull.12';		//is not null

const db_findinset		='<>db_findinset.13';		//find_in_set

const db_logic		='<>db_logic.100';		//where条件逻辑控制,and,or,xor等
const db_exp			='<>db_exp.101';		//表达式,特殊情况下使用
const db_null			='<>db_null.102';		//表示null,硬性约定
