Laravel merge two columns when querying LIKE

问题

I have a search input ?search=xxxx

I have two columns in my database first_name and last_name. I want the search to work for both of them, for example if my input is John Smith the search should be like CONCAT(first_name, last_name) ILIKE %input%

But laravel doesn't let me do it:

$customers = $customers->selectRaw("CONCAT('first_name', 'last_name') AS fullname")->where("fullname", "ilike", "%" . $text . "%");

Customers is already defined, and is an ORM object, not collection.

And the error i get for this:

SQLSTATE[42703]: Undefined column: 7 ERROR: column "fullname" does not exist LINE 1: ...) AS fullname from "people" where "type" = $1 and "fullname"... ^ (SQL: select CONCAT('first_name', 'last_name') AS fullname from "people" where "type" = customer and "fullname" ilike %fidel% order by "id" asc)

Also tried:

 $customers = $customers->whereRaw("CONCAT('first_name', 'last_name')", "ilike", "%" . $text . "%");

And another error:

SQLSTATE[HY093]: Invalid parameter number: parameter was not defined (SQL: select * from "people" where "type" = customer %fidel% CONCAT('first_name', 'last_name') order by "id" asc)

回答1:

There are multiple problems:

You can't wrap columns in single quotes. Use double quotes (or no quotes at all).
You can't access derived columns like fullname in the WHERE clause.
whereRaw() only has two parameters, the SQL string and an array of bindings.

Use this:

$customers->where(DB::raw('concat("first_name", "last_name")'), 'ilike', '%'.$text.'%');

I'm not sure what it is you are using based on how you are writing your code but if it is sql this might be what you are after...

DECLARE @cust_name VARCHAR(100) = 'john smith'  -- users input
DECLARE @first_name VARCHAR(50) = SUBSTRING(@cust_name, 1, CHARINDEX(' ', @cust_name) - 1)
DECLARE @last_name VARCHAR(50)  = SUBSTRING(@cust_name, CHARINDEX(' ', @cust_name) + 1, 8000) 


SELECT CONCAT(c.FirstName,c.LastName)
FROM 
    customers c
WHERE
    c.FirstName = @first_name
    AND c.LastName = @last_name
