ThinkPHP联表查询

1、table 方法

  

  原生sql方法

  原生sql语法:select 表1.字段,表2.字段 from 表1as 别名1,表名2 as 别名 2 where 表1.字段 = 表2.字段;

  select t1.*,t2.name as deptname from sp_user as t1,sp_dept as t2 where t1.dept_id = t2.id;

  $model -> table(‘表名1[as 别名1],表名2[as 别名2]……‘);

  $result = $model -> field(‘t1.*,t2.name as deptname‘) -> table(‘sp_user as t1,sp_dept as t2‘) -> where(‘t1.dept_id = t2.id‘) -> select();

2 、join方法

  select 表1.字段,表2.字段 from 表1 as 别名[inner/left/right] join 表2 as 别名 on 表1.字段 = 表2.字段;

  原生的sql:select t1.*,t2.name as deptname from sp_dept as t1 left join sp_dept as t2 on t1.pid;
