Question

我试图在laravel代码中创建一个临时表，插入值并在前端打印一些内容。但是我的临时表没有创建。

$temEmployee = DB::insert(DB::raw("CREATE TEMPORARY TABLE IF NOT EXISTS tmpEmp(
                tmpid INTEGER NOT NULL AUTO_INCREMENT PRIMARY KEY,
                NIC varchar(100),
                Designation varchar(100),
                WorkPlace varchar(100),
                Initials varchar(100),
                LastName varchar(100),
                DOB DATE,
                Mobile varchar(10),
                FirstAppoinment DATE,
                DutyAssumeDate  DATE
            )"));

我的代码有问题吗？

使用DB::statement();而非DB::insert();执行create table query

$temEmployee = DB::statement("CREATE TEMPORARY TABLE IF NOT EXISTS tmpEmp(
            tmpid INTEGER NOT NULL AUTO_INCREMENT PRIMARY KEY,
            NIC varchar(100),
            Designation varchar(100),
            WorkPlace varchar(100),
            Initials varchar(100),
            LastName varchar(100),
            DOB DATE,
            Mobile varchar(10),
            FirstAppoinment DATE,
            DutyAssumeDate  DATE
        )");
