Question

我在mysql SELECT TIMESTAMPDIFF(YEAR,birthdate,CURDATE()) AS age FROM employe where month(birthdate)=month(NOW())中的查询

获取该月的生日以及您的生日（从出生日期算起）。

在laravel中：

public function index()

{

    {


     $bird = DB::table('employe')

    ->whereraw('TIMESTAMPDIFF(YEAR,birthdate,CURDATE()) AS age FROM employe where month(birthdate)=month(NOW())') 

    ->select('employe.*')

    ->get();
    return response()->json(
        $bird->toArray()
    );

但是它会产生我错误

SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'AS edad FROM employe where month(birthdate)=month(NOW())' at line 1 (SQL: select `employe`.* from `employe` where TIMESTAMPDIFF(YEAR,birthdate,CURDATE()) AS age FROM employe where month(birthdate)=month(NOW()))

Answer 1

由于您拥有$bird = DB::table('employe')，查询生成器已经知道要选择FROM的表，这就是为什么您不需要FROM employe和->select('employe.*')
< / li> 查询的

TIMESTAMPDIFF(YEAR,birthdate,CURDATE()) AS age与WHERE子句无关。我们需要将其移至查询的SELECT部分。

$bird = DB::table('employe')
    ->select(DB::raw('*, TIMESTAMPDIFF(YEAR,birthdate,CURDATE()) AS age') 
    ->whereraw('MONTH(birthdate)=MONTH(NOW())')
    ->get();

如何将查询从mysql传递到laravel？
