Hello,

I am using MindTap in Cengage. I need help with the following problems for my DAT 380 Course:

Problem 16

Create the CUSTOMER table structure illustrated in Figure P8.16. The customer number should store integer values. The CUST_FNAME and CUST_LNAME attributes should support variable length character data up to 30 characters each. CUST_BALANCE should support up to eight digits on the left of the decimal place and two digits to the right of the decimal place. Use CUST_NUM as the primary key.

Problem 17

Create the INVOICE table structure illustrated in Figure P8.16. INV_NUM should store integer values. INV_DATE should store date values. INV_AMOUNT should support up to eight digits to the left of the decimal place and two digits to the right of the decimal place. Use INV_NUM as the primary key. Note that the CUST_NUM is the foreign key to CUSTOMER, so be certain to enforce referential integrity.

Problem 18

Write the set of SQL commands necessary to insert the data into the CUSTOMER table you created in Problem 16, as illustrated in Figure P8.16.

Problem 19

Write the set of SQL commands necessary to insert the data into the INVOICE table you created in Problem 17, as illustrated in Figure P8.16.

Use YYYY-MM-DD format when inserting dates.
