In this recipe, we will be learning how to remove a row from a database table. We assume that a database called ECommerce
already exists and a table called Users
also exists in the ECommerce
database. The Users
table consists of two columns, EmailAddress
and Password
. Also, we assume that the User
table contains a few rows in it. The user will be prompted to enter their email address and password in the form. The Users
table is searched for the specified email address and password. If any row is found with the specified email address and password in the Users
table, you will be prompted to confirm whether you are sure that you want to delete the row. If you click on the Yes
button, the row will be deleted.
