Hi Raj,
Do you have the HA300 CourseFiles for all exercises? I mean that folder named "Student" which includes some SQL script for HA300 exercises, for instance, 001_Preparation.sql, 002_CREATE_TABLE.sql, 003_INSERT_VALUES.sql, 004_SELECT_STATEMENT.sql, 005_SS##_PUPS_BOOKS.sql, they are mentioned in the course book page 56.
You said you have done practice with all the exercises available in HA300, then I suppose you should have it, would you pls kindly share it with me? Very very thank for your help. brianroe85@gamil.com
