tp5 資料庫Db查詢操作

$data = db::query('select * from tf_action');

$data = db::query('select * from tf_action where id > ? and id < ?',[1,10]);

$sql = db::getlastsql();

刪除，增加，修改，用execute。

$data = db::table('tf_action')->select();

$data = db::name('action')->select();

$data = db('action')->select();

但是又不完全相同。

$data = db('action')->where('id','>',1)->where('id','<',9)->select();

$data = db('action')->where('id','>',20)->whereor('id','<',9)->select();

如果中間的條件是空，就是=的意思。

$where = new where();

$where['name'] = ['like','%戶%'];
$where['id'] = ['>',1];
$data = db('action')->where($where)->select();

$where = ['name','like','%戶%'];

$where = ['id','>',1];
$data = db('action')->where($where)->select();

$where = new where();

$where['name'] = ['like','%戶%'];
$where['id'] = ['>',1];
$data = db('action')->where($where)->limit(2,2)->order('id desc')->select();

$where = new where();

$where['name'] = ['like','%戶%'];
$where['id'] = ['>',1];
$data = db('action')->where($where)->limit(2,2)->order('id desc')->field('id,name')->select();

$where = new where();

$where['name'] = ['like','%戶%'];
$where['id'] = ['>',1];
$data = db('action')->where($where)->limit(2,2)->order('id desc')->field('id aid,name')->select();

$data = db('action')->where($where)->field('count(*) as count')->find();

$data = db('action')->where("name like '%戶%' and id > 1")->select();
