Propose a method to authorize the users to SELECT from HR.EMPLOYEES table in the Oracle 18C database for only records within the same department as the user. Suppose the user's login name corresponds to the email field in the HR.EMPLOYEES table. For instance, the user DOCONNEL has DEPARTMENT_ID=50 and so he can only SELECT employee records in the same department. Your proposed method should work with any local user in the PDB. Describe the steps you take to test and verify that the access control is properly enforced. Provide relevant screenshots of the output of the SQL statements involved.

Solved in 2 steps
- Implement the following clauses on a database of your choice and produce results. (Writequery and add screen shot of your implementation)iv) Viewv) Group Byvi) Order Byvii) Like kindly answer the all parts i already posted 2 times this one question but there are are total 7 parts so kindly solve 4 prts.ignore the Answer:frequenceWrite a PL/SQL program with an IMPLICIT cursor that goes through the table KUCERA and measures the length of each word. Then it should insert every word into the correct table. So a word of length 3 letters, such as SHE would go into the table THREEL. All words with more than 5 letters go into the table MORETHANFIVEL.
- To test the text-provided implementations of min(), max(), floor(), ceiling(), select(), rank(), deleteMin(), deleteMax(), and keys(), create a test client called TestBinarySearch.java. Start by using the default indexing client. Add code to accept extra command-line arguments as needed.Consider the following command: UPDATE customerSET customer_id = customer_id --1; What happens if we run this command in MySQL? The customer_id in the customer table for all records is incremented by 1. The customer table has every customer_id set to the same value as it previously had. An error is thrown due to the --. The customer_id in the customer table for all records is decremented by 1.Try switching the joins pthread_join(tid2, NULL); pthread_join(tid1, NULL); Do you see any difference? Please report if and why you do or do not see any difference in terms of the randomness in the result of the shared resource. In the inc_dec_resource() function, implement mutual exclusion (pthread_mutex_lock) to ensure that the result becomes 0 every time when you execute your program. Put your updated code in the report (highlighted) and show your screenshot of the execution by running the script three time using $ time ./shared_resource_mutex. Hint: Your loop is incrementing/decrementing the resource which should be protected by each thread while it is executing that portion. #include <stdio.h> #include <pthread.h> #define iterations 300000000 long long shared_resource = 0; pthread_mutex_t mutex = PTHREAD_MUTEX_INITIALIZER; // Thread function to modify shared resource void* inc_dec_resource(void* arg){ //get the pointer from main thread and dereference it…
