Laravel 5.4 update all records in table without using where clause

Question

I am trying to update all records from table withing single eloquent query in Laravel 5.4

Currency::update(['default'=>0]);

I am expecting that this query will update all the records from a table, but this query isn't working. It is expecting where clause and I don't want to put any conditions using where clause, I just want to update all records in a table.

I am not getting any answer from laravel documentation.

Table Structure

Answer 1

MySQL has a safe update server mode which will not allow an update to happen unless the statement has a WHERE clause involving the primary key. If your MySQL be running in this mode, then one way to spoof it would be to use WHERE id = id , something like this:

DB::table('Currency')
        ->where('id', 'id')
        ->update(['default' => 0]);

Answer 2

If your MySQL server running SQL_SAFE_UPDATES mode you can use "where" like this. Or another "where clause" that includes all results.

Currency::where('id', '>', 0)->update(['default' => 0]);

Answer 3

Product::query()->update(['default' => 0, ]);
