Updating an access file using c Totally free private live sex chat
Therefore, this article gives you an idea how you can perform CRUD operations on JSON files and use JSON files as a database.Implementation For this demonstration, we will use the following JSON format.As you can see from the code, I called the Find method to find the row and called the Delete method of the Data Row.After that I called the Data Adapter's Update method to save the changes to the database table.
To access the nested data points, we need to iterate on JObject or JArray.The way the architecture works with the Data Adapter is that you can make any changes you want to the filled Data Set, and it won't affect the database until you call the Update method.When Update is called, the Data Adapter will attempt to execute each query (UPDATE, INSERT, DELETE) on every row of the Data Set that has been updated, inserted, and deleted.The Find method returns the row with Customer Id = Tst ID.After that I assign values of the row and call the Data Adapter's Update method. Updating data using the Data Adapter's Update method sender, System. Listing 5-50 deletes the row with the value Tst ID.
