Laravel Eloquent Compare Column Values

Question

Eloquent\'s where() seems not working when comparing two column values. How to fix it?

Sample code:

->where(\'table_1.name\', \'=\',          


        

Answer 1

Escaping is unnecessary in this case, you can use whereRaw():

->whereRaw('table_1.name = table_2.name')

Answer 2

I figured it out. 'table_2.name' is interpreted as plain string and not a mysql table column.

Possible solutions:

1. Wrap 'table_2.name'with \DB::raw()

   ->where('table_1.name', '=', \DB::raw('table_2.name'))
   

2. Wrap the entire expression with whereRaw() (based on @limonte's answer)

   ->whereRaw('table_1.name = table_2.name')
   

Answer 3

You can use where column:

->whereColumn('table_1.name', 'table_2.name')
