Google Web Toolkit Local Storage

Learn how you can implement the local storage using Google web tool kit.

Local storage helps you to keep the data on client machine or end user machine but never use an important data on local storage because local storage is not a secure storage.
Creating an instance using Storage class and also checking whether the browser supports local storage or not using getLocalStorageIfSupported() method.
Storage stockStore = Storage.getLocalStorageIfSupported();
Insert the data using setItem() method , fetch data using getItem() method and clear the local storage data using clear() method.

Solution : Cannot delete or update a parent row: a foreign key constraint fails

Whenever you want to delete a particular row from a parent table, usually a database engine checks whether this parent data primary key value refers to any child table data.

For Example,

Table: user

id login_Id user_Name 1 demo001 Note 2 demo002 Book
Table: userAddress

id user_id Country State 1 1 India Himachal Pradesh 2 2 India Tamil Nadu
Primary Key Foreign Key

Table UserAddress has “user_id” is a foreign key reference from Table User.

So User Table is Parent Table and UserAddress Table is Child Table

If you are try to delete any data in child table then you might be not facing an error but if you try to delete any data in parent table then you will face problem “Cannot delete or update a parent row: a foreign key constraint fails” because parent table data is referencing to child table.
