Question: Please do not spam answer me like other chegg peop...
Please do not spam answer me like other chegg people have. the question is not complicated but does require you to read the SQL table which I have created and supplied to answer the question. (provided below the question) IF you are NOT capable of answering please do not answer it, leave it for someone who can actually help me and not use up 1 of my paid questions.. I really appreciate the last question help from CHEGG EXPERT "Anonymous who has answered 2,421 answers..
********************Question to be answered below using the Table cod which i have provided beneath the question... THANK YOU SO MUCH!! This will help me so much to understand !
4A. Assume today is (July 27, 2017 at 2PM)*. Anita is due to check out today (from Part 1 above). Write an Update Statement to change the status of her Folio to 'CheckedOut. (Be careful to include a WHERE clause so ONLY here folio is updated). Note: This should automatically invoke tr_UpdateFolio above (factoring in the late charge), which automatically invokestr_GenerateBill above, and calls dbo.ProduceBill , and produces a bill.
*To simulate the current time as July 27, 2017 at 2PM, you will need to hard code the date value '7/27/2017 2:00:00 PM'.
4B. Assume today is (July 27, 2017 at 10AM)*. Write an Update Statement to change the status of her Folio to 'CheckedOut. Note: This should automatically invoke tr_UpdateFolio above (NOT factoring in the late charge), which automatically invokes tr_GenerateBill above, and callsdbo.ProduceBill , and produces a bill.
*To simulate the current time as July 27, 2017 at 10AM, you will need to hard code the date value '7/27/2017 10:00:00 AM'.
4C. Assume today is (July 27, 2017 at 6PM)*. Write an Update Statement to change the status of her Folio to 'C'heckedOut.
Note: This should automatically invoke tr_UpdateFolio above (NOT factoring in the late charge), which automatically invokes tr_GenerateBill above, and calls dbo.ProduceBill , and produces a bill.
*To simulate the current time as July 27, 2017 at 6PM, you will need to hard code the date value '7/27/2017 6:00:00 PM'.
4D. Run a SELECT statement on the Billing Table showing your Triggers worked.
