Mysql is not recognized as an internal or external command windows OS

Having XAMPP installed when i try to type mysql in my windows command prompt it would give me the following error:

'mysql' is not recognized as an internal or external command, operable program or batch file.

This simply means that the ‘mysql’ excutable command file (mysql.exe) was not added to your system path therefore the system was unable to locate this file. To add the ‘mysql’ to system path try to locate the ‘mysql’ resident folder. In my case (Windows7) it was

C:\Xampp\mysql\bin

Copy it (to clipboard) and go to Control Panel -> System and Security -> System and paste the copied folder path into Variable value: field of Edit System Variable pop up. Prefix it with a semi-colon (;) to separate it from other existing values (see image below – click to open larger image)

Magento2 showing error Required parameter ‘theme_dir’ was not passed while saving product in admin

This error appears when you remove a template folder, which is still referenced in the database. The simplest way to fix it is, go to database, and in table ‘theme’, find the theme name which does not exist in app/design/frontend/package.
DELETE the reference to the missing theme from the table.
