SQL - Part 24 - concat() MySQL String Function

You teach in very detail, hattsoff to you sir

Concat string function also not working sir

Sir we can concat only within the table or We can use concat with other table column

Sir, it's having an error as 'northwind. employees' doesn't exist.

Sir, please tell me the reason behind why I am getting the "Error 1: could not prepare statement (1 no such function: concat)"
