问题描述

我要实现不区分大小写的搜索 以下是我的搜索代码

I want to implement case insensitive search following is my code for search

/*get the title to search*/
$newsTitle=Input::get('srach_newsTitle')?Input::get('srach_newsTitle'):'';
$query = DB::table('news');
if( strlen($newsTitle) )
    {
        $query->whereRaw('LOWERCASE(`newsTitle`) LIKE ? ',[trim(strtolower($newsTitle)).'%']);
    }

但提示错误信息"LOWERCASE"未在我的项目"中定义

but its says function LOWERCASE is not Defined in My projects following is the error message

QueryException: SQLSTATE [42000]:语法错误或访问冲突:1305功能cpr-laravel.LOWERCASE不存在(SQL:从news中选择count(*)作为聚合，其中LOWERCASE(newsTitle)喜欢测试％)

QueryException in Connection.php line 729: SQLSTATE[42000]: Syntax error or access violation: 1305 FUNCTION cpr-laravel.LOWERCASE does not exist (SQL: select count(*) as aggregate from news where LOWERCASE(newsTitle) LIKE test%)

我在做什么错?请帮忙

使用LOWER()

$query->whereRaw('LOWER(`newsTitle`) LIKE ? ',[trim(strtolower($newsTitle)).'%']);
