laravel5+复杂原生sql编写多条件查询定位经纬度距离排序及paginate分页

描述:laravel链式操作虽然方便那是针对普通业务,稍微复杂点的我感觉还是原生sql来的实在
话不多说分享一下一个案例:
多条件查询,定位经纬度计算距离附近排序,分页
$where = request()->input();
if (!isset($where['lng']) || !isset($where['lat'])) {return '未传经纬度';}
try {
$sql = "SELECT
lara_90_cbb_palmlife.id,
lara_90_cbb_palmlife.tid,
lara_90_cbb_palmlife.city,
lara_90_cbb_palmlife.area,
lara_90_cbb_palmlife.business,
lara_90_cbb_palmlife.type_name,
lara_90_cbb_palmlife.img,
lara_90_cbb_palmlife.title,
lara_90_cbb_palmlife.lat,
lara_90_cbb_palmlife.lng,
lara_90_cbb_palmlife.youhui,
round(st_distance_sphere(point(lara_90_cbb_palmlife.lng,lara_90_cbb_palmlife.lat),point({$where['lng']},{$where['lat']}))/1000,2) as space
FROM
`lara_90_cbb_palmlife`
LEFT JOIN `lara_92_cbb_palmlife_coupon_relation` ON `lara_90_cbb_palmlife`.`tid` = `lara_92_cbb_palmlife_coupon_relation`.`palmlife_id`
LEFT JOIN `lara_91_cbb_palmlife_coupon` ON `lara_91_cbb_palmlife_coupon`.`cid` = `lara_92_cbb_palmlife_coupon_relation`.`palmlife_coupon_id`
WHERE ";
if (isset($where['city'])) {
$sql .= "city = '{$where['city']}'";
}
if (isset($where['area'])) {
$sql .= " and area = '{$where['area']}'";
}
if (isset($where['business'])) {
$sql .= " and business = '{$where['business']}'";
}
if (isset($where['type'])) {
$sql .= " and type_name = '{$where['type']}'";
}
if (isset($where['bank'])) {
$sql .= " and lara_90_cbb_palmlife.bank = {$where['bank']}";
}
if (isset($where['bank'])) {//查优惠表
$sql .= " and (lara_91_cbb_palmlife_coupon.bank = {$where['bank']} or lara_91_cbb_palmlife_coupon.bank is NULL)";
}
if (isset($where['week'])) {//查优惠表
$sql .= " and (youhui LIKE '%周一至周日%' OR lara_91_cbb_palmlife_coupon.title LIKE '%{$where['week']}%' )";
}
if (isset($where['kw'])) {
$sql .= " and lara_90_cbb_palmlife.title like '%{$where['kw']}%'";
}
$sql .= "GROUP BY lara_90_cbb_palmlife.tid";
if (isset($where['space'])) {//1000千米内距离排序 根据定位跟经纬度计算距离
$sql .= " HAVING space < {$where['space']} ORDER BY space ASC , lara_90_cbb_palmlife.id" ;
}else{
$sql .= " ORDER BY space ASC , lara_90_cbb_palmlife.id";
}
//$sql .= " LIMIT 100";
//$res = DB::select($sql);
$sql = '('.$sql.') cc';//定义临时表
$res = DB::table(DB::raw($sql))->paginate(10);
return response()->json(array('status' => 200, 'msg' => '成功', 'res' => $res));
} catch (Exception $e) {
return response()->json(array('status' => 201, 'msg' => '失败'));
}
