laravel5 中的日期数据类型更新

Question

i am updating data posted from form. one of the column is of datatime datatype in mysql.

All the data is updating except the Datetime column.

My code is as below

DB::table('CANDIDATE')
->where('CANDIDATEID',$ID)
->update(
        [
        'fname'=>$fname
        ,'mname'=>$mname
        ,'lname'=>$lname
        ,'genderid'=>$GENDERID
        ,'dob'=>$dob
        ,'address'=>$address
        ,'city'=>$city
        ,'pinno'=>$pinno
        ,'statesid'=>$STATESID
        ,'countryid'=>$COUNTRYID
        ,'contactno'=>$contactno
        ,'industryprtid'=>$INDUSTRYPRTID
        ,'cur_prof_titl'=>$cur_prof_titl
        ,'skills'=>$skills
        ,'certificate'=>$certificate
        ,'emp_typeid'=>$EMPTYPEID
        ,'experienceid'=>$EXPERIENCEID
        ,'educationid'=>$EDUCATIONID
        ,'edu_major'=>$edu_major
        ,'other_detail'=>$other_detail
        ,'mainobj'=>$mainobj
        ,'relocate'=>$relocate
        ,'sal_rngid'=>$sal_rngid
        ]

);

What is wrong in the code.

Answer 1

Laravel does not set the timestamps when you're using the fluent builder instead of using Eloquent. So you'll need a model for this.

Fluent builder will not set timestamps

DB::table('CANDIDATE')
    ->where('CANDIDATEID', $ID)
    ->update(
    // ...

Eloquent model will:

<?php namespace App\Namespace;

use Illuminate\Database\Eloquent\Model;

class Candidate extends Model
{
    // Model foo here
}

And then use:

App\Namespace\Candidate::where('CANDIDATEID, $ID)
    ->update(
    // ...

Given that you do have the default laravel timestamp columns available in your table. (created_at, updated_at).

Unrelated, but worth mentioning:

If/when possible, check your naming convention, it will be easier to follow the Laravel naming convention for table and column names (eg use candidates as table name and candidate_id for column names.)
