Exercises on usage of INSERT, UPDATE, DELETE, and MERGE statements
Here you can practice in solving exercises on data modification (which in combination with SELECT statement present Data Manipulation Language - SQL DML). These tasks are included in the first certification stage, however, they are unaccessible without registration because of calculating time spent on solving each exercise in the same manner as it has been done for the second testing stage on SELECT statement.
