如何在 laravel 中的 mysql 查询生成器中转换为标题大小写

Question

I just want to ask how to convert the data I'm getting from database in Title case, its giving me an error:

Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use

I'm just using UCASE and LEFT, here's my code,

DB::raw('GROUP_CONCAT(DISTINCT " " ,
    CONCAT(UCASE(LEFT(ru.firstname, " ", ru.lastname, 1)))) AS relates_to')

The output I want for example is "user name" into "User Name", oh and I'm using the latest MySQL Workbench just to inform you

Hope you can help me and notice me, thank you so much in advance.

The LEFT function only takes two parameters, so this alone would cause your current code to fail. You may try reworking it as follows:

DB::raw("GROUP_CONCAT(DISTINCT ' ' , LEFT(UCASE(CONCAT(ru.firstname, ' ', ru.lastname)), 1)) AS relates_to")

I don't know what your logic is exactly trying to achieve, but the above should at least run without error.
