Using Insert query you can insert records in table

query for update column value

UPDATE Student SET City = 'xyz' WHERE StudentId = 1

Answer 2

When you work with a database, you typically use an editor program or IDE which can connect to the database, then it will inform you about the execution of your statements. You can run each statement separately, or together in batch (as a script). Good IDE programs will also let you browse the tables in a GUI, and view and even directly modify data. Not every editor supports every type of database, and some of them cost money. There are many free / open source ones also, for example DBeaver that has wide range of support for different databases.
