将varchar字符串转换为日期格式查询Laravel

Question

I'm having a trouble on how can I convert my filename into date time format. The format of my filename is varchar and The problem is the last part of the name file is not formatted as a date it should be formatted in hour , minutes and AM/PM see my sample image below. do you have any idea of this? change from 33250400 to 01-47 PM. It would be great if anybody could figure out, thank you so much in advance..

Expected output

2021-03-30-01-47 PM.csv

What I've tried

 ->select(['table.*',DB::raw(' DATE_FORMAT(table.file_name, "%Y-%m-%d-%h:%i %p") AS final_date')

Answer 1

You are passing filename to DATE_FORMAT function which contains.csv extension that is why you are not getting your expected output but if you still want date time format of filename then you can select records from database and you can remove.csv extension from each filename record string and then use date function to get your desired output
