how to retrieve a particular row from MySQL database and to use them in react native?
Okay, suppose you get an array of responses from the api call in backend (i.e php) , like [{"id":"1","cus_name":"k","cmpny_name":"k","gst_no":"k","mob_no":"k","user_id":"k","password":"k"}]
So suppose youget response in a variable eg
response = [{"id":"1","cus_name":"k","cmpny_name":"k","gst_no":"k","mob_no":"k","user_id":"k","password":"k"}]
Now to extract id of first element just do ,
response[0]['id'] , and this will give out the value 1. coz id is 1.
Hope it helps. feel free for doubts

I have an ecommerce website, using Laravel and mysql. I need to auto change the currency based on the client country.
I already have the selection based currency change. I need to auto change the currency to the one of the user's country when visiting the website.
We have a laravel package called Torann/laravel-geoip for this purpose.
Add below snippet after finished installing this lib;
$geoData = geoip(request()->ip());
$currency = $geoData['currency'];

What will be the query in rails or mysql to do it for all the data in the database?
You can use simple update query using REPLACE function:
UPDATE `table_name` SET `id_token` = REPLACE(`id_token`, 'ank', 'cus');

I need to display the list of staffs who check into work late in a week. For example the staff checks in at 8.10 when the supposed check in time is at 8.00 AM. I am using datetime for the datetimein and datetimeout field. Can anyone suggest how should I do it?
Well, with no sample tables to work from, it's hard to give a clear answer. But I think what you're looking for is the TIME() function.
This should get you started in the right direction:
SELECT * FROM timeclock_records where TIME(datetimein) > "08:00:00";

Here im going to create a database in phpMyadmin.it shows this is not a number error.Here i have attached the image.When im going to save it shows
This is not a number!
You have to enter length for IsActive as it is of type BIT. In Mysql BIT field requires a length to be assigned.
