Step by step
Solved in 3 steps
- individual characters using their 0-based index. Hint: You will need to do this for checking all the rules. However, when you access a character .In the BOOK_PRICING database, the Category field should be marked as obsolete. Make sure the column has been marked as unavailable.The SERVICE_REQUEST table uses the CHAR data type for the DESCRIPTION and STATUS fields. Is there an alternate data type that could be used to store the values in these fields? Justify your reason for choosing an alternate data type or for leaving the data type as CHAR.
- How do you indicate that a column alias should be used?Save the changes permanently to the database.Create a new table containing the category code and description for the categories of books sold by JustLee Books. The table should be called CATEGORY, and the columns should be CatCode and CatDesc. The CatCode column should store a maximum of 2 characters, and the CatDesc column should store a maximum of 10 characters.

- SQL: Add a table-level PRIMARY KEY constraint to the EMPLOYEE table using the ID column. The constraint should be named at creation. (Which means you'll need to drop the table, then recreate.) Create a PRIMARY KEY constraint on the DEPARTMENT table using the ID column. The constraint should be named at creation. (Which means you'll need to drop the table, then recreate.) Add a foreign key reference on the EMPLOYEE table that will ensure that the employee is not assigned to a nonexistent department. Confirm that the constraints were added by querying USER_CONSTRAINTS. Note the types and names of the constraints and include them in your statement comments. Display the object names and types from the USER_OBJECTS data dictionary view for EMPLOYEE and DEPARTMENT tables. You will want to format the columns for readability. Provide comments that include the new tables and indexes created. Modify the EMPLOYEE table by adding a SALARY column of NUMBER data type, precision 7.
