SQL语句更新列

Question

How I can add a column in a sql parameter on laravel 5.3?

I have a table with: id,name,zipcode,nearag1 and a variable named agent

I want a SQL statement for laravel 5.3 like this:

*UPDATE items set near_ag1=ABS(zipcode-$agent)* traslate to laravel 5.3 

I made a SQL raw statement like this:

$Agzc1= $request2->input('Agzc1');

Item::raw("UPDATE items set near_ag1=ABS(zipcode-?)",[$Agzc1]); 

This SQL produces no errors but the column near_ag1 is saving 0 values.

有一种用于绑定的方法，您不应该完全生硬，因此：

Item::update(['near_ag1' => DB::raw('ABS(zipcode-?)'))->setBindings([$Agzc1]);
