Explanation

Data Manipulation Language (DML) commands allow you to insert or update records and extract information from records for viewing (a query): INSERT INTO TableName - adds a new row in a table in the database. UPDATE TableName - changes the value of one or more table columns. This can be used with a WHERE statement to filter the records that will be updated. If no WHERE statement is specified, the command applies to all the records in the table. DELETE FROM TableName - deletes records from the table. As with UPDATE, this will delete all records unless a WHERE statement is specified. SELECT - enables you to define a query to retrieve data from a database.
